[00:04:06] <zeeshan|2> :P
[00:04:46] <zeeshan|2> that my friend is an machinetoolswarehouse cnc machine
[00:04:50] <zeeshan|2> ih clone
[00:05:33] <[cube]> hmm nice
[00:05:33] <zeeshan|2> how much
[00:05:34] <[cube]> good call!
[00:05:46] <[cube]> worth a grand?
[00:05:48] <XXCoder> 1200
[00:05:51] <zeeshan|2> lol
[00:05:53] <zeeshan|2> thats cheap for that
[00:06:04] <zeeshan|2> cube
[00:06:09] <zeeshan|2> do you know what size table is on it?
[00:06:13] <zeeshan|2> that'll tell me if its a rf45
[00:06:16] <zeeshan|2> or ih
[00:06:35] <zeeshan|2> https://www.machinetoolswarehouse.com/xcart/catalog/MD001-IH-Clone-p-16133.html
[00:06:37] <zeeshan|2> compare it to that
[00:06:40] <[cube]> no idea, 0 info other than photo
[00:06:48] <zeeshan|2> it looks very much like that
[00:06:55] <XXCoder> blue
[00:06:55] <zeeshan|2> its 2500 + tax new
[00:06:58] <XXCoder> pic its all black
[00:07:00] <zeeshan|2> i know.
[00:07:00] <[cube]> yeah it does
[00:07:03] <zeeshan|2> you dcan get it in different colors
[00:07:09] <[cube]> R8
[00:07:38] <[cube]> the control panel reminds me of craftex/grizzly
[00:07:39] <zeeshan|2> you can do damage with that machine
[00:07:51] <zeeshan|2> https://www.youtube.com/watch?v=fD14mxH4xjI
[00:08:03] <zeeshan|2> its pretty much what tormach uses
[00:08:06] <zeeshan|2> and builds around
[00:08:09] <[cube]> 1000 lbs yikes
[00:08:16] <zeeshan|2> thats good :D
[00:08:31] <[cube]> i guess i'll need more than a minivan :)
[00:08:39] <XXCoder> nahhh
[00:08:46] <zeeshan|2> is that seriously up for 1000 bux
[00:08:47] <zeeshan|2> ?

[00:09:00] <[cube]> i dont think it'll last long
[00:09:01] <zeeshan|2> before someoenf inds out what it is
[00:09:06] <[cube]> well
[00:09:12] <[cube]> the post he's selling a 'press'
[00:09:17] <[cube]> 80 ton shop press
[00:09:23] <[cube]> and its liek a secondary listing

[00:10:01] <[cube]> sec
[00:10:17] <XXCoder> I found and bought it
[00:10:19] <XXCoder> sorry
[00:10:21] <XXCoder> JK lol
[00:10:26] <[cube]> haha
[00:10:28] <zeeshan|2> XXCoder: hows your work going
[00:10:34] <zeeshan|2> wow
[00:10:36] <zeeshan|2> thats a sexy pres
[00:10:42] <XXCoder> great! was tiring though
[00:10:50] <XXCoder> dunno why was simple jobs today
[00:10:56] <zeeshan|2> cube
[00:10:57] <XXCoder> anyway time sleep laters
[00:10:59] <zeeshan|2> rape his phone number
[00:11:02] <zeeshan|2> !
[00:11:06] <zeeshan|2> gnite XXCoder
[00:11:24] <XXCoder> I leave you guys with this https://en.wikipedia.org/wiki/Cube_%28film_series%29
[00:11:28] <XXCoder> expecially you [cube]
[00:11:31] <zeeshan|2> i cant believ he was selling both those
[00:11:34] <zeeshan|2> for 2k
[00:11:35] <zeeshan|2> LOL
[00:11:39] <[cube]> must need cash
[00:11:41] <zeeshan|2> XXCoder: that movie awesome
[00:11:46] <[cube]> I 've seen that whole series :P
[00:11:57] <[cube]> even the one with felix from road to avon lea :P
[00:12:07] <zeeshan|2> have yuou watched the movie

[00:12:33] <zeeshan|2> i mean the movie
[00:12:34] <zeeshan|2> :-)
[00:12:38] <[cube]> tremors is a great classic

[00:15:47] <[cube]> hes good in this one movie i saw recently...
[00:15:49] <[cube]> Death Sentence
[00:17:09] <zeeshan|2> hm
[00:17:11] <zeeshan|2> havent seen that one
[00:17:14] <zeeshan|2> must watch :D
[00:24:57] <LeelooMinai> How do you call hexagonal inserts threded on inside, like that? http://i.imgur.com/m0q21tF.png
[00:26:14] <[cube]> looks like a spacer
[00:26:44] <[cube]> http://uk.rs-online.com/web/p/threaded-hex-spacers/1057372/
[00:27:03] <LeelooMinai> O, ok, spacer then
[00:29:24] <LeelooMinai> Not sure if this is metalworking terminology though. Maybe spacer/standoff is more for pcbs, etc.
[00:29:55] <[cube]> ya that sounds right as well
[00:30:13] <LeelooMinai> I searched KBC for spacer and could not really find it
[01:06:48] <roycroft> i've heard of them referred to a spacers/standoffs, primarily in electronics work and couplers in general machinery/mechanical work
[01:08:27] <roycroft> http://www.portlandbolt.com/products/nuts/hexcouplingnut.html
[01:17:21] <Connor> standoff
[01:17:49] <Connor> LeelooMinai: We call them standoff's
[01:29:00] * Jymmm calls em a failure to communicate protest!
[01:30:10] <Jymmm> oh, nylon standoffs
[01:30:24] <Jymmm> or aluminum standoffs
[01:48:08] <Jymmm> LeelooMinai: Metalurgical geometric lifter upper thingymabobs
[02:14:06] <Deejay> moin
[03:40:54] <Loetmichel> mornin'
[03:45:25] <Tom_itx> http://www.digikey.com/product-detail/en/4808/4808K-ND/255345
[03:47:13] <archivist> they should state metal or spastic
[03:47:36] <Tom_itx> http://www.digikey.com/product-detail/en/8405/8405K-ND/255372
[03:47:58] <Tom_itx> they do
[03:48:01] * archivist demands brass
[03:48:09] <Tom_itx> pfft
[03:49:26] <Tom_itx> http://www.digikey.com/product-detail/en/R30-3002002/952-1510-ND/2264491
[04:56:05] <kengu> ideas on spindle for 70mm mount for fireball v90?
[04:57:32] <kengu> or some other dimension spindle as mounts are available http://www.probotix.com/spindles_and_mounts/
[05:12:24] <MarkusBec> where can i find a how to for building a modified FW for the mesa FPGA cards?
[06:38:51] <alex_joni> Jymmm: what kind of RF?
[06:39:44] <alex_joni> here are some for wifi connectors: http://www.wifimarket.ro/default-14-Cabluri_Pigtailuri_Mufe.html
[07:08:35] <Tom_itx> MarkusBec, http://tom-itx.ddns01.com:81/~webpage/emc/xilinx/xilinx14_install_index.php
[07:08:50] <jdh> there are lots of chinese 65mm and 80mm spindles (re: v90)
[07:09:06] <Tom_itx> MarkusBec, unless you meant the FPGA firmware itself
[07:38:42] <MarkusBec> Tom_itx: ok thanks
[07:39:12] <MarkusBec> that is what I am looking for
[07:39:39] <Tom_itx> i just added a couple pointers to the page so if you had it open you may wanna refresh
[07:53:00] <Jymmm> ##hamradio
[07:55:41] <archivist> Jymmm, how many hams would want http://www.collection.archivist.info/searchv13.php?searchstr=ring+nut
[07:58:33] <Jymmm> archivist: Most of the time its the radio / ,ic's pinout that's needed
[07:58:47] <Jymmm> mic's*
[07:59:27] <Jymmm> oh, you mean the tool?
[07:59:36] <archivist> yes
[08:00:42] <Jymmm> Hams are cheap bastards alot of the time. Unless one is into restorations, I think they would look for an alternative tool.
[08:01:09] <Jymmm> ...instead of a speciality one-time use one
[08:01:18] <archivist> I spent ages googling, so has the person who asked me to make that one
[08:02:05] <archivist> but I do know the cheap bastards problem
[08:02:16] <_methods> what dia is that spanner nut driver?
[08:02:38] <archivist> 19mm od
[08:02:54] <Jymmm> archivist: Could try http://www.eham.net/classifieds/?view=all
[08:03:23] <jthornton> cd emc-degarr
[08:03:25] <jthornton> opps
[08:03:44] <_methods> heheh
[08:05:16] <_methods> ugh gotta go to customer site
[08:05:30] <_methods> i kinda like going to this place though
[08:05:45] <_methods> they make like giant cable for undersea lines
[08:05:45] <Jymmm> _methods: strip club?
[08:05:48] <_methods> hahah
[08:05:49] <_methods> i wish
[08:05:56] <_methods> nexans built a new plant here
[08:06:25] <_methods> the sheating that goes on the outside of the cable has this crazy smoothing contraption
[08:06:39] <XXCoder> sheating is that shitty heating? ;)
[08:06:40] <Jymmm> _methods: I avoid strip clubs, it's like a giant tease, you can look but no touch.
[08:06:47] <_methods> hehe indeed
[08:07:59] <Jymmm> archivist: Can you make a order page for it?
[08:08:21] <Jymmm> archivist: BUY NOW payapl thingy
[08:08:32] * jthornton forgets how to checkout a branch :(
[08:08:41] <archivist> chaisaw
[08:08:48] <archivist> chainsaw
[08:09:00] <Jymmm> Got Hatchet?
[08:10:27] <Jymmm> archivist: Honestly, if I needed a tool, I'd have gotten a piece of tubing and filed back till I got the profile
[08:10:32] <jthornton> in this example on the wiki I don't understand the syntax git checkout -b v2.5_branch origin/v2.5_branch
[08:11:05] <jthornton> what does origin/v2.5_branch do?
[08:11:25] <archivist> a url for git to go look at methinks
[08:11:37] <Jymmm> git checkout -b|-B <new_branch> [<start point>]
[08:11:46] <jthornton> thanks
[08:12:11] <Jymmm> http://git-scm.com/docs/git-checkout
[08:12:17] <archivist> but dont listen to me as never used git
[08:13:05] <jthornton> hey that worked
[08:13:07] <Jymmm> Specifying -b causes a new branch to be created as if git-branch[1] were called and then checked out. In this case you can use the --track or --no-track options, which will be passed to git branch. As a convenience, --track without -b implies branch creation; see the description of --track below.
[08:13:07] <Jymmm> If -B is given, <new_branch> is created if it doesn’t exist; otherwise, it is reset. This is the transactional equivalent of
[08:13:07] <Jymmm> $ git branch -f <branch> [<start point>]
[08:13:08] <Jymmm> $ git checkout <branch>
[08:13:10] <Jymmm> that is to say, the branch is not reset/created unless "git checkout" is successful.
[08:18:41] <Jymmm> archivist: I would have used a right-angle tips of a snap ring pliers http://www.northerntool.com/images/product/2000x2000/909/9094251_2000x2000.jpg
[08:19:34] <Jymmm> https://ff3d8e6495061f28a832-a7869bbdcfcea96a643a5d6aa79482f7.ssl.cf1.rackcdn.com/enlarged/08-0279.jpg
[08:21:29] <archivist> they may not fit in the recess, but I am wondering what percentage are not cheap barstards and need the spanner...1, 10, 100(profit)
[08:22:49] <Jymmm> archivist: How much (apx) ?
[08:24:07] <archivist> 10-15$ or 10-15£
[08:24:27] <Jymmm> plus another $8 for shipping?
[08:24:41] <archivist> I suppose
[08:27:04] <Jymmm> I don't know even if *I* would pay $20 for it. I mean it's literally a one-time use tool. The rarity of having to replace a mic jack is really high up there. That takes a full disassembly of the radios' chassis, adn that in itself is a big clusterfuck. So unless I had to do it multiple times, rapair depot or someone who does restorations is where it seems useful
[08:28:27] <Jymmm> And most mic nuts today are hex
[08:29:59] <Loetmichel> ouch... i just sneezed 3 times so hard the co-worker 3 doors away on the shitter nearly fell of it... and now my ribs hurt each draw of breath.
[08:29:59] <Loetmichel> ... co-worker called via wireless( FROM THE toilet) "BLESS YOU, here are the windwos still shaking" ;-)
[08:30:00] <archivist> I think one maker used that form, the rest used hex from the rear
[08:30:01] <Jymmm> But then again, some like to boast about having specialty tools like that , or are part of a club and willing to loan it out too
[08:31:35] <Jymmm> archivist: The thing I would do is find out which rigs use that style, and include that wiht any ads for it
[08:32:05] <archivist> trio kenwood did
[08:32:39] <Jymmm> archivist: There are the big three... Kenwood, Icom, and Yaesu. But which model rigs
[08:33:31] <Jymmm> http://www.universal-radio.com/catalog/hamhf/730lrg.jpg
[08:35:27] <Jymmm> archivist: That's the rig I have and it uses it (sorta), but it's recessed even more so that I would have to take off the face plate to get to the nut
[08:35:57] <Jymmm> and that's a old rig too
[08:36:14] <archivist> mine is recessed like that and that driver fits it :)
[08:38:11] <Jymmm> archivist: Many of these bastards will spend thousands on a rig, but only $0.99 on a DVM to adjust that rig.
[08:38:44] <archivist> yup, met the type
[08:39:00] <archivist> model engineers are similar
[08:39:06] <Jymmm> archivist: But like I said, there are those that like having specialty tools just for bragging rights too
[08:39:31] <Jymmm> archivist: be sure to include a url and model number on it =)
[08:39:36] <Jymmm> for reorders
[08:40:12] <Jymmm> I dont know how many times Ive seen somethign very useful and the person can't remember where they got it from, and no markings on it
[08:42:11] <Jymmm> archivist: Call it a "rig wrench" or something unique enough to make ppl curious enough to just find out what it is =)
[08:43:37] <Jymmm> archivist: Or instead of a 1/4" hex on the back side, make it flippable and dual purpose
[08:43:58] <archivist> needs a sensible drive method
[08:44:14] <Jymmm> http://www.thunderboltrc.com/images/SparkPlug-Wrench.jpg
[08:44:17] <Jymmm> like that =)
[08:45:04] <archivist> that is mass produced and done hot
[08:45:20] <Jymmm> Do you think they care?
[08:45:22] <Jymmm> http://img1.wfrcdn.com/lf/49/hash/9013/3491556/1/Spark+Plug+Socket+Wrench.jpg
[08:45:55] <Jymmm> Spanner one end, hex on the other would be good
[08:46:23] <Jymmm> let them use theri own philips screwdrver for the "handle"
[08:46:36] <Jymmm> you supply the hole for it to fit into =)
[08:48:33] <Jymmm> http://www.1977mopeds.com/media/catalog/product/1/9/1977_moped_parts_Spark-plug-Tool-123.jpg
[08:49:50] <Jymmm> archivist: A lot of today's rigs use RJ-45's now.
[08:50:35] <Jymmm> archivist: http://www.universal-radio.com/catalog/hamhf/3991lrg.jpg
[08:52:12] <archivist> yuk
[08:52:22] <Jymmm> yuk?
[08:52:45] <Jymmm> 897 is almost 15 years old, just discontinued http://www.eham.net/data/classifieds/images/359564.jpg
[08:56:17] <archivist> using rj 45 for any non stationary application
[08:56:17] <Jymmm> archivist: Also, if that's aluminum, wouldn't it start rounding over the nibs? I think it would have to be hardened steel
[08:56:57] <archivist> it is steel, the nuts are probably brass, the socket itself is zinc
[08:57:25] <Jymmm> ah ok. looks aluminum in the pics
[08:59:47] <Jymmm> the mic jacks I have are pot metal nuts (magnetic), but the bodies are non-magnetic
[09:06:45] <Jymmm> alex_joni: Thanks
[09:32:08] <Jymmm> 38F/3C FUCK A DUCK!!!
[09:32:14] <Jymmm> 89% Humidity
[09:32:36] <Jymmm> and not a cloud in the sky
[09:42:11] <Deejay> re
[09:42:33] <Jymmm> Deejay: er
[09:43:08] <Deejay> hoi jymmm
[09:43:14] <Jymmm> =)
[09:58:35] <FinboySlick> If you need to replace a bga chip on a board nowadays, is it still: "You're pretty much screwed." ?
[09:58:48] <SpeedEvil> no
[09:59:04] <SpeedEvil> Preheat the board to ~80C.
[09:59:12] <SpeedEvil> Mask off area round BGA
[09:59:20] <SpeedEvil> Use hot-air rework station to remove BGA
[09:59:35] <SpeedEvil> add lots of flux, and use wick and stuff to clean off the board.
[09:59:47] <SpeedEvil> Alcohol to clean off flux remnants
[10:00:09] <SpeedEvil> Now, stencil on some fresh solder-paste, and reflow the BGA
[10:00:27] <skunkworks> easy peasie
[10:00:34] <skunkworks> ;)
[10:01:03] <FinboySlick> Heh, well *I*'m probably still screwed then.
[10:02:07] <FinboySlick> I don't even know which of the chips it is :P
[10:08:19] <SpeedEvil> why do you think you need to replace it
[10:13:08] <jdh> did you try plugging in the power?
[10:13:53] <archivist> diagnosis beats guessing
[10:22:38] <jdh> swap out chips until it works.
[10:23:33] <archivist> I remember an idiot engineer that did that, his work always looked a mess
[10:25:57] <Jymmm> heh
[10:26:36] <archivist> scatter gun method of repair
[10:26:39] <Jymmm> Hell, even doctors dont do diagnostics anymore. Just write a script to deal with the effects.
[10:30:49] <Jymmm> They don't call it a Medical PRACTICE for nothing =)
[10:58:19] <FinboySlick> SpeedEvil: One of the RAM chips on a way-too-expensive video card went bad. There's about 2GB and I only get errors around 1800GB so I know it's probably 'the last one'. I'm just not sure which one that means on the layout.
[10:58:38] <SpeedEvil> ah
[10:58:52] <SpeedEvil> you might try heating/cooling
[10:59:04] <SpeedEvil> that may remove the fault or make it worse andthenyoucan tellwhich
[10:59:20] <SpeedEvil> Itcould also be that simply reflowing it will help
[11:08:27] <renesis> heh, careful
[11:08:53] <renesis> gpu usually have lots of inductors, connectors, parts both sides
[11:09:18] <renesis> those things are prob a pain to reflow in production lab environments
[11:19:34] <SpeedEvil> yeah - hence masking
[11:33:45] <renesis> i would just hot air around the chip pins
[11:34:20] <renesis> low heat, low pressure
[11:35:32] <jdh> interleaved mem?
[11:35:58] <LeelooMinai> If not interleaved one could just find it watching temperature on them
[11:36:22] <LeelooMinai> But if interleaved - probably not:)
[11:37:07] <jdh> newegg
[11:37:32] <renesis> i cant afford a newegg
[11:38:16] <renesis> this egg needs more rams but its ddr2 i dont want to spend
[11:38:24] <jdh> I actually despise newegg
[11:38:30] <renesis> rly?
[12:14:26] <bobo_> bobo is now known as bobo
[12:14:31] <_methods> is there a "better" connector to use than the GX (aviation) connectors for control boxes?
[12:15:49] <Jymmm> wire nuts or duct tape
[12:16:05] <Jymmm> CONUCTIVE duct tape
[12:21:46] <_methods> heheh
[12:24:05] <jthornton> tig welding
[12:24:59] <renesis> hey wire nuts are the shit
[12:25:18] <renesis> id take a wire nut over some IDC bullshit
[12:25:56] <jthornton> 3m makes the best wire nuts
[12:26:17] <jthornton> I tossed all the other brands in the trash after getting them
[12:46:41] <malcom2073> Twist the wires together, over-current them to weld.
[12:46:45] <malcom2073> done
[12:46:49] <malcom2073> :P
[12:50:06] <_methods> heheh that's how i connect all my wires silly
[12:50:41] <_methods> gx connectors are so 80's
[12:50:53] <_methods> i was hopin someone had a line on some sexier connectors
[12:51:16] <_methods> some hot pink hello kitty bulk head fittings or something
[12:59:13] <jthornton> what are you trying to connect?
[12:59:31] <_methods> steppers, power
[12:59:35] <_methods> you know stuff
[12:59:56] <jthornton> well terminal blocks does come to mind then
[13:00:26] <_methods> i just got some gx connectors
[13:00:36] <jthornton> if I was connecting a stepper to a drive I'd run the cable right to the drive
[13:00:43] <jthornton> what's a gx connector?
[13:00:52] <_methods> chassis mount connectors
[13:01:02] <_methods> or "aviation" connectors
[13:01:08] <jthornton> got a link?
[13:01:48] <roycroft> i'm using gx connectors for the float switches on my brew system
[13:01:49] <_methods> https://encrypted-tbn3.gstatic.com/images?q=tbn:ANd9GcSdu-eJgxMe-Br6siUaiMCU2mKHr4mAEaPw08pc6uls0LUMTOBi
[13:01:55] <roycroft> they were cheap
[13:02:05] <_methods> yeah they are cheap
[13:02:14] <_methods> i was looking for something "different"
[13:02:20] <jthornton> oh your looking for a plug and socket for the cabinet
[13:02:21] <roycroft> they are also different
[13:02:25] <_methods> yeah
[13:02:35] <roycroft> i'm using different types of connectors for each type of probe/switch/whatever
[13:02:40] <jthornton> do you plan on moving it around a lot where you need to unplug them?
[13:03:06] <_methods> nah i just like to have a clean connection
[13:03:13] <roycroft> i'm using xlr connectors for the electric valves
[13:04:01] <jthornton> the cleanest (electrical) connection is a cord grip
[13:04:33] <_methods> cord grip?
[13:04:36] <jthornton> I use multi cord cord grips http://www.mcmaster.com/#standard-cord-grips/=ur1mfk
[13:04:40] <_methods> like a cable gland?
[13:04:47] <jthornton> might be
[13:05:11] <_methods> yeah
[13:05:34] <_methods> well that just gets the cable through the chassis/bulkhead
[13:05:59] <roycroft> xlr are pretty clean
[13:06:25] <_methods> yeah
[13:07:24] <_methods> get some crazy milspec connectors
[13:08:11] <_methods> nm i don't have that much money lol
[13:08:29] <_methods> http://www.mcmaster.com/#circular-power/control-connectors/=ur1o4j
[13:08:58] <_methods> no wonder tanks cost so much
[13:10:50] <roycroft> they cost so much because they're manly
[13:11:16] <roycroft> converting testosterone into steel is an expensive industrial process
[13:17:10] <_methods> fo sho
[13:38:03] <JT-Shop> I need a 17mm ball cammed up for the lathe... anyone bored
[14:02:14] * JT-Shop wonders how he can trick his cam to create an XZ path for the lathe
[14:02:55] <cradek> heh for a while I did that with realize
[14:03:06] <cradek> I might've just changed Y to Z in the output - not sure
[14:03:23] <cradek> and hand- tweaked it of course
[14:03:43] <JT-Shop> realize?
[14:04:01] <cradek> uh http://timeguy.com/cradek/autocad
[14:04:11] <cradek> but even I don't use it anymore
[14:04:26] <cradek> somewhere along the line I quit being able to get qemu to run freedos
[14:04:54] <anonimasu> Hello,
[14:05:00] <anonimasu> pcw_home: are you around=
[14:05:01] <anonimasu> ?
[14:28:44] <_methods> heh wooden watches
[14:28:46] <_methods> http://www.springbreakwatches.com/
[14:34:17] <PetefromTn_> jeez....why?
[14:34:22] <_methods> no idea
[14:35:07] <PetefromTn_> there are a lot of materials I can think of to make a cool watch out of.....wood is not really one of them.
[14:35:32] <_methods> maybe because they don't have shop class in school anymore?
[14:35:50] <PetefromTn_> I weep for the future
[14:36:20] <_methods> i can't wait to watch it all
[14:36:45] <PetefromTn_> my wife and kids are off all the rest of the week so this is gonna be a nice Thanksgiving break I think.
[14:36:57] <_methods> i'm off after today
[14:36:59] <_methods> 1 hour left
[14:37:27] <PetefromTn_> any CNC mill work you don't get to send it my way I will do it while you are chilling out LOL
[14:37:45] <_methods> hehe we actually are really busy right now
[14:38:02] <_methods> 3 months ago i wasn't sure if i'd have a job this time
[14:38:16] <PetefromTn_> man thats nice
[14:38:20] <_methods> i was pretty sure it was gonna be an ugly xmas
[14:38:28] <_methods> but now we have an 8month backlog
[14:38:36] <_methods> so it's all giggles for now
[14:39:27] <PetefromTn_> I'm kinda worried about Christmas here.... work has been REAL slow lately.
[14:39:44] <_methods> yeah that was me a couple months ago
[14:40:10] <PetefromTn_> I just bid a neat job for a fellow machinist
[14:40:13] <_methods> buwhahahahhahahahhah check this out
[14:40:15] <_methods> http://www.ebay.com/itm/Zuo-Era-Modern-Pastelite-Table-Lamp-Pipe-Blue-Glass-Industrial-Steampunk/131296036264
[14:40:23] <_methods> $249 lol
[14:40:28] <PetefromTn_> it is for some steel plate work.
[14:40:43] <_methods> someon has been hittin the "pipe"
[14:41:28] <renesis> someone will pay that\
[14:41:28] <PetefromTn_> sad news is they will probably sell a million of em..
[14:41:36] <renesis> i wonder if the valve turns it on and off
[14:41:40] <_methods> hahah
[14:41:44] <_methods> i hope so for that price
[14:42:11] <renesis> ikr
[14:42:45] <JT-Shop> change Y to Z and J to K and done deal
[14:42:50] <renesis> that would by far be the most challenging part of the project
[14:43:07] <renesis> jt-shop is rappin
[14:43:31] * JT-Shop is changing a mill path to a lathe path
[14:43:52] <renesis> wut
[14:44:33] <PetefromTn_> you trying to do some turning in a vertical mill?
[14:45:33] <JT-Shop> no, my cam program only outputs mill cam and I'm turning a ball on the lathe
[14:46:42] <PetefromTn_> You don't have a lathe cam package?
[14:47:19] <JT-Shop> no, I do 95% of my lathe work using ngcgui
[14:48:17] <PetefromTn_> I am anxious to see how I get on with a CNC lathe
[14:48:31] <PetefromTn_> I will undoubtedly do my lathe work in CAM as much as possible
[14:48:43] <PetefromTn_> but I am curious about the NGCGUI setup for quick stuff
[14:50:29] <JT-Shop> ngcgui will do anything other than profiles faster than you can cam it up
[14:50:48] <PetefromTn_> profiles? How so.
[14:50:50] <JT-Shop> you can even take a profile path and keep offsetting it if you like
[14:51:53] <JT-Shop> lathe ops like facing, chamfering, OD turning, drilling, tapping, boring can be programed in seconds
[14:52:44] <PetefromTn_> that sounds great.
[14:53:07] <PetefromTn_> are they kinda one at a time things or can you put together a comprehensive program using them and then run the whole thing again?
[14:53:39] <JT-Shop> yea, you can concatenate all the ops to one in the order you want
[14:53:50] <PetefromTn_> sounds sweet.
[14:54:10] <PetefromTn_> I cannot wait to have a CNC lathe running in here. There are so many things I want to do with it.
[14:54:30] <JT-Shop> what I usually do for more than one part is to program each op and run it then when all ops are programmed I concatenate them to one and start firing parts off
[14:54:36] <PetefromTn_> This machine should be awesome once it is functional.
[14:54:49] <PetefromTn_> yes exactly how I would want to work.
[14:55:06] <PetefromTn_> I used to basically do everything like that before I got more comfortable with programming.
[14:55:22] <PetefromTn_> Even with CAM I do that sometimes when I am not sure how things will go.
[14:55:29] <PetefromTn_> One tool and one op at a time
[14:55:36] <PetefromTn_> until I get a completed program and part.
[14:55:51] <PetefromTn_> Then the next one is just post the whole code and run thru after making any adjustments.
[14:56:38] <PetefromTn_> who made the NGCGUI?
[14:58:27] <JT-Shop> Dewey Garrett
[15:04:11] <PetefromTn_> cool
[15:05:46] <LeelooMinai> I will ask again my yesterday's question, since I went to sleep:) Could I but hexagonal threaded pieces like this in a matal shop like KBC? I don't know if they have some specific name (searched for spacers, bit no hit): http://i.imgur.com/m0q21tF.png
[15:05:52] <LeelooMinai> but=buy
[15:06:13] <LeelooMinai> I mean a bigger ones, say with M5 ot M6 thread
[15:06:26] <PetefromTn_> that is a threaded coupler
[15:06:34] <PetefromTn_> they sell them in lots of different sizes
[15:06:42] <PetefromTn_> try Mcmaster carr
[15:06:43] <LeelooMinai> Coupler, ok, let me see
[15:09:51] <LeelooMinai> I found something close under "coupling nut": http://www.homedepot.ca/product/1-8-hex-coupling-nut/955827
[15:10:25] <LeelooMinai> I guess this would embed nicely in my epoxy granite table
[15:10:36] <LeelooMinai> And would not rotate
[15:12:38] <SpeedEvil> Rotation is irrelevant
[15:12:53] <SpeedEvil> In that the tension will pull it out first
[15:12:59] <_methods> ^^
[15:13:07] <JT-Shop> heh
[15:13:46] <_methods> i'd use kingserts if i was going to do something like that
[15:13:46] <LeelooMinai> Well, it depends on the construction - in my case they will be screwed from bottom, so good luck with that:)
[15:13:54] <_methods> they're all knurled
[15:14:18] <JT-Shop> you didn't say that...
[15:14:43] <LeelooMinai> I also did not say they will be not attached from the bottom:)
[15:15:09] <JT-Shop> one never assumes
[15:15:09] <LeelooMinai> Are kinserts those to rework threads?
[15:15:26] <LeelooMinai> Or kingserts
[15:15:29] * JT-Shop having produced zero today goes to take the dog for a walk
[15:15:30] <_methods> nm what i said
[15:15:55] <_methods> you don't need kingserts if you're screwing them into something below
[15:15:55] <SpeedEvil> JT-Shop: take a bag, in case the dog produces something
[15:16:56] <_methods> you just need threaded standoffs
[15:18:27] <Tom_itx> JT-Shop, you need gcode for a ball?
[15:19:27] <_methods> bah all this time i thought it was kingsert and it's actually keensert
[15:20:44] <_methods> ez-locks would also probably work too if you weren't fastening them to some substructure
[15:22:44] <LeelooMinai> Right, I will see what's available in stores near me
[15:38:53] <JT-Shop> Tom_itx, I converted an XY to XZ
[15:39:03] <Tom_itx> what tool are you using?
[15:39:22] <JT-Shop> 0.250 round insert
[15:39:26] <Tom_itx> and are the tools on the back side?
[15:39:55] <Tom_itx> do you know the sanvik number for it?
[15:40:00] <Tom_itx> ie CNMG etc
[15:40:16] <JT-Shop> no, my tools are front
[15:40:29] <JT-Shop> I don't use sanvik tools
[15:40:30] <Tom_itx> just opposite andys
[15:40:41] <Tom_itx> well it's industry standard naming
[15:40:54] <Tom_itx> i haven't done enough lathe to remember
[15:41:21] <JT-Shop> it's a round insert as in totally round
[15:41:35] <Tom_itx> ok
[15:41:48] <Tom_itx> material diameter?
[15:42:05] <JT-Shop> I've already converted a mill path to the lathe
[15:42:10] <Tom_itx> i know
[15:42:15] <Tom_itx> it's just an exercise
[15:42:16] <JT-Shop> 1"
[15:42:27] <JT-Shop> want a dxf?
[15:42:50] <Tom_itx> ok
[15:42:59] <Tom_itx> i about got it though
[15:43:13] <Tom_itx> except i don't know the profile on the end of it
[15:43:55] <JT-Shop> on the Z- side it is a 7/16 cylinder that sticks out 3/16"
[15:46:49] <Tom_itx> .250 fillet where they join?
[15:47:01] <JT-Shop> yea
[15:47:34] <Tom_itx> how are you doing the cutoff on the ball end?
[15:48:46] <JT-Shop> I'm threading and facing the back side then mounting that on a threaded thing
[15:48:47] <_methods> i need to check the fusion 360 and see if it will do lathe tool paths
[15:49:15] <Tom_itx> oh the nub gets threads?
[15:50:06] <JT-Shop> internal threads yea
[15:51:26] <Tom_itx> you should use 3/4" bar
[15:51:42] <JT-Shop> ?
[15:52:02] <Tom_itx> save material
[15:52:16] <Tom_itx> 17mm is .6693
[15:52:25] <JT-Shop> ah, yes... wonder if I have any 3/4 bar
[15:52:56] <LeelooMinai> Hmm, I should put some construction inside the table, like they do with concrete, right? Something cheap - threaded rods maybe or just rebar (but they are 10mm in diameter - kind of brutal)?
[15:52:57] <Tom_itx> gotta watch the bottom line ya know!
[15:53:32] <JT-Shop> gotta use drops lol
[15:53:36] <Tom_itx> i really should set up a tool table for lathe like i did for mill
[15:55:13] <JT-Shop> I do have a bit of 3/4"
[15:55:24] <Tom_itx> SS ?
[15:56:22] <JT-Shop> 6061
[15:57:06] <Tom_itx> fewer passes too... less machine time
[16:04:40] <Connor> OKay.. Got my replacement Pendant - HB04 unit... this one is working correctly.. no loosing which direction the MPG is turning.
[16:10:23] <JT-Shop> best get off my butt and make one to see
[16:11:49] <Tom_itx> how deep of cuts are you taking?
[16:19:38] <LeelooMinai> http://i.imgur.com/ag8aYMU.png <- why would they copper plate it?
[16:20:01] <roycroft> so the weld spatter does not stick
[16:20:13] <roycroft> those clamps are made for welding
[16:20:15] <LeelooMinai> weld what? :)
[16:20:40] <LeelooMinai> A, some molten metal flying?
[16:20:45] <roycroft> whenever you see clamps with copper plated screws they're designed for welding
[16:21:10] <LeelooMinai> I see, ok - I thought it was weird someone would copper plate a screw
[16:21:33] <roycroft> there is always a reason to add a process to manufacuring
[16:21:35] <Tom_itx> ok i get something like RNMG230 for an insert
[16:21:36] <roycroft> manufacturing
[16:21:51] <Tom_itx> not sure about the '0' designation
[16:22:52] <renesis> guys you ever take plates of delrin and smack your head with it because it makes a funny thump because so light and rigid?
[16:23:17] <LeelooMinai> No, I use surface plate for that:p
[16:24:10] <renesis> =(
[16:24:15] <renesis> thats not ok
[16:24:23] <renesis> for your head or the surface plate
[16:24:57] <LeelooMinai> Is derlin some kind of nicely machinable desnse plastic?
[16:25:26] <renesis> its acetyl, harder than nylon
[16:25:28] <LeelooMinai> I think I read once about it, but found it too be expensive
[16:27:22] <LeelooMinai> Is building my table to work with this a good idea? Would such a system cover most of the clamping needs? http://i.imgur.com/mhRGrWv.png
[16:28:01] <LeelooMinai> Seems to be not very expensive
[16:28:09] <Deejay> gn8
[16:28:16] <renesis> get pretty far with that
[16:28:44] <LeelooMinai> Not sure what are all the parts for - like the "studs"
[16:29:16] <LeelooMinai> O, I know - they go through those slots there
[16:29:26] <ve7it> LeelooMinai, I use a set like that.... it would sometimes be handy to have 2 sets to clamp bigger/odd shaped objects
[16:30:01] <Jymmm> LeelooMinai: https://d2t1xqejof9utc.cloudfront.net/screenshots/pics/3d9e6206fe2e85d23dee76d8effaa889/medium.JPG
[16:30:14] <Connor> That's a standard clamp set.. studs thread into the T nuts that go into the table..
[16:30:24] <LeelooMinai> Hmm, I see. What size would be good for a cnc table?
[16:30:27] <Connor> clamps go over stud..
[16:30:36] <Connor> Size is based on the T-Slot size.
[16:30:43] <Jymmm> http://halfbakedmaker.org/wp-content/uploads/2010/03/IMG_0272.jpg
[16:31:05] <LeelooMinai> Right, I did not decide yet what size to make the slots - seems there are many sizes and no standard ones?
[16:31:14] <JT-Shop> Tom_itx, 0.025 deep
[16:31:43] <LeelooMinai> There are 6 clamps there - I guess I could always buy another set, but for starters one should do.
[16:32:08] <Connor> 7/16" probably good for a little router.
[16:32:44] <Jymmm> LeelooMinai: http://www.rockler.com/48-universal-t-track-with-hold-down-clamps
[16:32:59] <LeelooMinai> Doesn't have to be tiny. My table is 21 by 21 inches. I would rather have something oversized but standard.
[16:33:24] <LeelooMinai> That seems like some woodworking system
[16:33:46] <Jymmm> and?
[16:33:46] <LeelooMinai> I want to clamp aluminum piecesa
[16:33:56] <Jymmm> ok
[16:34:02] <LeelooMinai> I don't know - seems flimsy to me
[16:34:06] <Connor> 1/2 probably next size up would be your best bet.
[16:34:21] <Connor> That's what the G0704 uses.
[16:34:37] <LeelooMinai> And what if Gxxxx?
[16:34:39] <LeelooMinai> is*
[16:34:46] <roycroft> i would recommend getting standard t-slots such as are used on milling machines and the like
[16:34:55] <Connor> G0704 is model # of my Mill
[16:34:57] <roycroft> and using machinists clamps
[16:35:01] <Connor> http://www.grizzly.com/products/Drill-Mill-with-Stand/G0704
[16:35:12] <LeelooMinai> roycroft: Yes, thats what I am trying to find out - what is that standard:)
[16:35:30] <LeelooMinai> Is the shape standardized or dimensions?
[16:35:31] <roycroft> like this:
[16:35:33] <roycroft> http://www.amazon.com/Anytime-Tools-Slot-CLAMP-CLAMPING/dp/B007DMLBZ6
[16:35:33] <Connor> LeelooMinai: No STANDARD. Depends on the size and class of the machine and T-SLot sizes.
[16:36:09] <LeelooMinai> roycroft: That seems like what I linked from KBC
[16:36:12] <roycroft> you can get those in larger sizes, but with your machine being rather small and lightweight, the 3/8" kit will probably be fine
[16:36:19] <roycroft> i didn't see you link anythign
[16:36:20] <LeelooMinai> roycroft: http://i.imgur.com/mhRGrWv.png
[16:36:35] <roycroft> i have more things to do than watch this channel, so i miss a lot
[16:36:54] <LeelooMinai> Yes, well, that's what I was shooting for
[16:37:00] <JT-Shop> buying tooling before you have the machine done...
[16:37:20] <LeelooMinai> JT-Shop: Don't do that - build the machine first:)
[16:37:37] <roycroft> jt-shop: in this case, as leeloominai doesn't know what he's doing, it makes sense to talk about the clamping system before finishing the machine
[16:37:45] <roycroft> that will help him design proper t-slots for the machine
[16:37:52] <LeelooMinai> I am not buying anything - I am researching sizes so I build the table right
[16:38:01] <JT-Shop> that makes sense
[16:38:09] <LeelooMinai> And I am "she" not he
[16:38:12] <roycroft> sorry
[16:38:14] <Connor> LeelooMinai: 7/16 or 1/2 to slots
[16:38:16] <roycroft> a poor assumption to make
[16:38:23] <Connor> would be good for your size of machine.
[16:38:35] <LeelooMinai> Right, I think I will just decide on 1/2
[16:39:01] <roycroft> i use a 1/2" set when i'm working on a bridgeport-style mill
[16:39:04] <Connor> how much Z travel you have ?
[16:39:04] <LeelooMinai> Non-metric, but it seems being in Canada I am doomed with imperial:)
[16:39:07] <roycroft> and 3/8" on my little s3 clone
[16:39:27] <LeelooMinai> I measured travel 2 days ago, let me see
[16:40:05] <roycroft> so yes, that 1/2" set from kbc would be fine
[16:40:08] <roycroft> that uses 3/8" studs
[16:40:18] <roycroft> and is probably quite appropriate for your machine
[16:40:52] <roycroft> you can order the t-slot nuts in almost any size
[16:41:07] <roycroft> i make my own, as i think most machinsts do
[16:41:37] <LeelooMinai> 33cm X 29cm Y and 14.6cm Z
[16:41:46] <roycroft> although you're not going to be able to do that on the machine you're building
[16:41:55] <LeelooMinai> SO Z is 7.5"
[16:41:57] <Connor> 5.7" okay.. not bad.. mine has 4.5"
[16:42:16] <LeelooMinai> E, right
[16:42:45] <LeelooMinai> I made gantries taller, because I knew I will have to make some DIY table and may end up with something tall
[16:43:07] <Connor> I have 6" clearance.
[16:43:34] <roycroft> at the sacrifice of stability
[16:45:28] <LeelooMinai> When they write "stud size" 3/8-16 is that inner thread?
[16:46:00] <LeelooMinai> SO the nut is 1/2" wide and has this thread inside it?
[16:46:06] <roycroft> yes
[16:46:20] <Connor> 3/8 stud
[16:46:34] <JT-Shop> they should list the dimensions of the tee nut
[16:46:40] <roycroft> you might order the clamping kit so you can measure the t-slot nuts and make sure they fit the table you're designing
[16:46:45] <roycroft> they may
[16:47:05] <roycroft> certainly when you order t-slot nuts standalone the dimensions are stipulated
[16:47:07] <LeelooMinai> How about the thickness of the slot "flanges" - does it matter?
[16:47:45] <roycroft> at the very least they should be thick enough so that the t-slot nuts do not stick up above the surface of the table
[16:48:08] <LeelooMinai> Hmm, right
[16:48:34] <roycroft> the thicker they are the stronger they will be
[16:48:54] <roycroft> it depends in part on how hard you rank down on the clamping nuts
[16:49:05] <roycroft> btw, when the time comes, get yourself a set or two of 1-2-3 blocks
[16:49:15] <LeelooMinai> I have those
[16:49:19] <roycroft> you'll find them quite handy for supporting material on the table
[16:49:22] <LeelooMinai> BOught them once from KBC on sale
[16:49:38] <roycroft> thick parallels are also useful
[16:49:43] <LeelooMinai> Was using them when building the frame for CNC
[16:49:49] <roycroft> and an angle block or two
[16:50:02] <LeelooMinai> Parallels are those two triangles that slide?
[16:50:14] <roycroft> those are adjustable parallels
[16:50:24] <roycroft> i'm talking about the regular ones that come in pairs
[16:50:37] <roycroft> you can get them in varying thicknesses - get a nice thick set like 1/4" or more
[16:50:44] <roycroft> and you can use them to support things on the table
[16:51:40] <roycroft> although since this is going to be a cnc machine, for most things you can just put a piece of sacrificial wood/sheet metal under your work and machine a few thousandths deep
[16:52:05] <LeelooMinai> Hmm, what are they used for normally? They just look like rectangular pieces of metal to me:)
[16:52:20] <roycroft> you stick them in a milling vice to support your work
[16:52:32] <roycroft> vise, even
[16:52:36] <roycroft> although milling can be a vice
[16:53:14] <LeelooMinai> I see, like that: http://www.mini-lathe.org.uk/images/use_engineering_parallels.jpg
[16:53:33] <LeelooMinai> So they have basically very parallel sides and that's all
[16:53:59] <roycroft> yes
[16:55:25] <LeelooMinai> OK, will buy them with the clamping set after I build the table
[16:56:21] <JT-Shop> you use parallels with your vise to raise the material up
[16:57:02] <LeelooMinai> I don't really have a vise for such precise work - I just have a drill press and cheap 2-way vise
[16:57:16] <roycroft> when working on a milling machine you generally want your work to be above the top of the vise jaws
[16:57:27] <roycroft> so that you can surface it, etc. without damaging the jaws
[16:57:33] <roycroft> parallels support the work so that you can do that
[16:57:40] <LeelooMinai> Right
[16:57:48] <roycroft> which is why they generally come in sets of pairs, at different heights per pair
[16:57:56] <rob_h> just dont forget them when you drill through ;)
[16:58:05] <JT-Shop> http://www.physics.wisc.edu/ishop/images/defimages/parallels.gif
[16:58:10] <roycroft> that's why there are thin paralles and wavy parallels
[16:58:21] <JT-Shop> lol shoot the parallel out the side when you drill too close
[16:58:32] <rob_h> or just make vise jaws :)
[16:59:03] <roycroft> if you have a precision vise you can usually remove the paralles once the work is clamped in the vise
[16:59:19] <roycroft> if you have a $1000 chinese vise you had best leave the parallels installed
[16:59:26] <roycroft> er, $100
[16:59:28] <JT-Shop> dang if my drill bit jumped off center when it started in the hole, now I have to make a new one
[16:59:44] <roycroft> making drill bits is a lot of work
[17:00:49] <JT-Shop> lol
[17:01:28] * JT-Shop guesses he should have used a spotting bit first
[17:01:41] <rob_h> or a 3 flute drill and drill on any surface ;)
[17:02:04] <JT-Shop> wish I had a crib full of them but I don't even have one
[17:02:12] <roycroft> i usually start a hole with a center drill even when using a hand drill
[17:02:18] <JT-Shop> I have a few parabolic bits
[17:02:31] <tjtr33> if you didnt drill too depp, you can 'box' it back into center using punch
[17:02:39] <JT-Shop> I was told not to use a center drill to spot drill with
[17:02:49] <JT-Shop> wrong angle or something like that
[17:03:03] <rob_h> it can be for carbide drills as most are newer angle points
[17:03:05] <roycroft> i was trained to use one
[17:03:13] <rob_h> so just use the correct C/d
[17:03:53] <roycroft> center punch -> center drill -> undersize twist drill -> reamer for the perfect semi-precise hole
[17:04:20] <roycroft> replace reamer with boring bar for the perfect precise hole
[17:04:23] <ssi> spotting drills are the jam
[17:04:59] <roycroft> or just get out the cutting torch and blast a hole through the metal for the fast hole
[17:05:18] <LeelooMinai> Or shoot at it with a gun
[17:05:32] <JT-Shop> I see the keyless chuck is not centered anymore so I need to indicate it... wonder how it got off
[17:07:38] <PetefromTn_> center drills suck for predrilling drill bit holes..
[17:08:12] <_methods> nine
[17:08:17] <_methods> everede nine
[17:08:49] <_methods> http://everede.net/nine9_2013_ncsd_n9mt05t1.html
[17:08:57] <PetefromTn_> nice stuff...
[17:09:03] <_methods> i love them things
[17:09:04] <Rab> PetefromTn_, why is that?
[17:09:12] <PetefromTn_> I just use a simple spot drill
[17:09:17] <_methods> tool #1 in every machine
[17:09:22] <PetefromTn_> yeah
[17:09:26] <PetefromTn_> why is what?
[17:09:47] <_methods> cause everyone in the shop knows tool1 is everede
[17:09:56] <_methods> we put all the same tools in all the same holders
[17:10:01] <_methods> so everyone knows
[17:10:06] <_methods> all the same pots
[17:10:11] <_methods> 1/2-13 tap
[17:10:13] <_methods> m6 tap
[17:10:16] <PetefromTn_> hm
[17:10:16] <_methods> m12 tap
[17:10:19] <_methods> all tap drills
[17:10:31] <_methods> that way when you program something it will go between any machine
[17:10:32] <Rab> PetefromTn_, was just confused. I didn't realize spot and center drills were different things.
[17:10:37] <PetefromTn_> you must do a lot of the same stuff.
[17:10:38] <_methods> you don't have to change too many tool #'s
[17:10:40] <tjtr33> "boxing a drill" https://www.youtube.com/watch?v=ESWzx3YBo3g
[17:10:58] <tjtr33> very old school
[17:11:00] <PetefromTn_> yeah a center drill is mostly for drilling a location point for a lathe center.
[17:11:09] <_methods> well you'd be suprised at how often you use all th same tools
[17:11:10] <PetefromTn_> the angles are correct for it,
[17:11:17] <_methods> taps, drills, end mills
[17:11:28] <PetefromTn_> spot drills are for starting drills etc.
[17:11:37] <PetefromTn_> Oh I agree
[17:11:55] <PetefromTn_> I use the same six tools for MOST stuff and then change drill bits and taps etc for the job at hand,
[17:11:56] <roycroft> well a spotting drill is usually 90 degrees, and a standard twist drill is ground to 118 degrees, so there's already an angle mismatch there
[17:12:13] <PetefromTn_> But I do not have that many holders
[17:12:27] <_methods> yeah oh i'm not sayin it's for everyone
[17:12:28] <PetefromTn_> Spotting drills are available in many different flavors
[17:12:52] <_methods> but those everedes are worth every penny
[17:12:57] <_methods> you can use them to spot and chamfer
[17:13:10] <roycroft> oh, yes, i see some 118 degree ones now
[17:13:13] <PetefromTn_> I know you told us about them before I think..
[17:13:19] <_methods> yeah sorry
[17:13:21] <_methods> heheh
[17:13:22] <roycroft> i've never seen them in a shop, but the enco catalog has them
[17:13:27] <_methods> i ramble on about them
[17:13:34] <PetefromTn_> don't be sorry not everyone may have been listening
[17:13:52] <PetefromTn_> has what?
[17:13:54] <_methods> i need to pick a couple up for me at the house now
[17:14:17] <roycroft> and they're not really that expensive
[17:14:31] <roycroft> i'll order some next time i buy tooling and see what i think
[17:15:15] <_methods> they're great for production cause you can just swap out the insert and the operator can get back to pressin that big fat green button
[17:15:47] <_methods> and you get 4 sides out of the 90deg inserts
[17:16:20] <PetefromTn_> do they work for tiny drills?
[17:16:28] <_methods> probably not
[17:16:34] <PetefromTn_> IE what size do you recommend?
[17:16:50] <_methods> there's a radius on the tip so i'd stay over that
[17:17:11] <_methods> radii depends on the insert
[17:17:21] <_methods> but that one i linked has a .016" rad
[17:17:57] <PetefromTn_> their pictures suck on that website.
[17:18:03] <PetefromTn_> Can't blow them up either it seems
[17:18:23] <_methods> i think they have a big pdf you can download
[17:19:53] <_methods> yeah under comprehensive list of literature they have pdf's for all their stuff
[17:20:09] <_methods> i've never used any of their other stuff
[17:20:27] <PetefromTn_> hm
[17:20:33] <PetefromTn_> just downloaded it.
[17:21:05] <PetefromTn_> I think for what I am doing while it would be nice to have an insert bit I have never actually dulled or broken my spotting drill
[17:21:24] <PetefromTn_> That thing cuts beautiful and is pretty cheap to replace
[17:22:39] <_methods> yeah it's probably not worth the money unless you got "operators" lol
[17:23:01] <_methods> inserts just make things so much easier when you're dealing with the lowest common denominator lol
[17:24:17] <PetefromTn_> well like I said I would probably make better use of a dedicated champfer tool over that even tho you said it can do champfers. I do a lot of champfering on my parts. Good surface finish is most important.
[17:24:50] <_methods> yeah i love it cause i can do my spotting and chamfering without having to do a tool change
[17:25:03] <_methods> but for a heavy chamfer i'll still go to a real chamfer tool like a umax
[17:27:26] <PetefromTn_> The Champfer I do on my Steyr Rail is 6061 aluminum about 3/8 face so not heavy but it is done on the loading port area and needs to look good. I could probably get a better finish with a dedicated champfer tool over the makeshift one I currently use. I often have to make due with less than ideal stuff. unfortunately
[17:27:41] <Tom_itx> JT-Shop how'd your part come out?
[17:27:46] <LeelooMinai> Any recommendations on the distance between t-slots on a table?
[17:27:57] <_methods> i consider a 3/8 chamfer to be heavy
[17:27:58] <Tom_itx> 3"
[17:28:00] <LeelooMinai> 1/2 t-slots that is
[17:28:02] <_methods> that's a decent chamfer
[17:28:13] <Tom_itx> 2"?
[17:28:19] <_methods> you couldnt do that in one pass with the everede
[17:28:28] <_methods> i don't think at least
[17:28:37] <PetefromTn_> LeelooMinai Honestly for a machine like yours I would look to getting a tooling plate with a pattern of tapped holes instead of tee slots.
[17:28:57] <PetefromTn_> LOL I do it in one pass with my SPECIAL tool
[17:29:09] <_methods> heheh
[17:29:09] <PetefromTn_> about 6k RPM and 14 IPM
[17:29:25] <PetefromTn_> well actually thats not true
[17:29:37] <PetefromTn_> first there is a smaller champfer made all around the top edge of the part
[17:29:39] <LeelooMinai> PetefromTn_: T-slots seem easier for me to do for cheap. Also, aren't they nicer because you can slide the nuts in them into any position?
[17:30:02] <PetefromTn_> then I make the deeper champfer pass
[17:30:10] <PetefromTn_> so it is not full blown depth
[17:30:19] <_methods> yeah 3/8" chamfer is pretty beefy chamfer
[17:30:34] <PetefromTn_> LeelooMinai Honestly while it seems that way I always find that the damn slots are never where they need to be
[17:30:35] <_methods> plus you need a cosmetic chamfer
[17:30:42] <JT-Shop> Tom_itx, the keyless chuck offset was borked somehow so it got trashed... still making the fixture lol
[17:31:06] <Tom_itx> i just got back to the cad.. had to feed first
[17:31:07] <LeelooMinai> PetefromTn_: Wouldn't it be even worse for just threaded holes? :)
[17:31:19] <Tom_itx> JT-Shop, how deep a cut are you taking?
[17:31:23] <PetefromTn_> http://i.imgur.com/6TCytja.jpg you can see the champfer in this picture in the center of the part
[17:31:50] <PetefromTn_> LeelooMinai Well not if you make enough holes..
[17:32:01] <PetefromTn_> Most tooling plates have a BUNCH of holes everywhere around the plate.
[17:32:03] <JT-Shop> 0.025"
[17:32:10] <LeelooMinai> PetefromTn_: I can also make a lot of t-slots I guess
[17:32:11] <JT-Shop> when I get that far
[17:32:11] <Tom_itx> i figured .020
[17:32:14] <Tom_itx> pretty close
[17:32:27] <PetefromTn_> the hold down allow you to swivel your position somewhat
[17:32:31] <JT-Shop> yea 20 or 25 what ever it takes
[17:32:33] <Tom_itx> i have the paths pretty well done
[17:32:40] <Tom_itx> if it's the right machine
[17:33:20] <_methods> yeah that's a good chamfer even in alum
[17:33:40] <Tom_itx> i don't like the lathe package as good as the mill because i can't edit the tooling from within the cad
[17:34:22] <_methods> that is a beautiful rail
[17:34:35] <PetefromTn_> LeelooMinai It is difficult to make a flat plate with that many tee slots I think. Plus you weaken it. I know there are LOTS of CNC machines that came with Tee slot tables that are covered with cast tooling plates with tapped hole patterns so there must be a reason for that.
[17:34:52] <PetefromTn_> thanks man
[17:34:57] <PetefromTn_> I am kinda proud of it
[17:35:03] <_methods> you should be
[17:35:07] <PetefromTn_> I am right this minute making a new version
[17:35:13] <_methods> have you anodized any yet?
[17:35:15] <PetefromTn_> this one has picatinny rails on it.
[17:35:22] <PetefromTn_> no I do not have that ability yet
[17:35:50] <_methods> do some of that cool "paint splatter" anodize
[17:35:56] <PetefromTn_> I really need to invest in it I could really make the parts pop then.
[17:36:02] <PetefromTn_> How is that done?
[17:36:06] <PetefromTn_> I love that look
[17:36:10] <_methods> i have no idea
[17:36:15] <PetefromTn_> probably a beotch
[17:36:15] <_methods> but paintball guys all got it
[17:36:25] <_methods> i think you can do it in your garage
[17:36:36] <_methods> but i honestly don't know
[17:36:41] <PetefromTn_> I guess at some point after you anodize it then it has that matte look and you can just splash color onto it before you seal it.
[17:36:51] <_methods> i hate painting, coating, finishing
[17:37:07] <_methods> i sub that part out lol
[17:37:15] <PetefromTn_> yeah I do too so far.
[17:37:22] <_methods> too much headache
[17:37:33] <PetefromTn_> most guys do not get it tho just a brushed or bead blasted finish and they are happy.
[17:37:53] <PetefromTn_> I am excited to see this same rail with the picatinny profile on it.
[17:37:54] <_methods> yeah that paintball crowd loves flashy colors
[17:38:02] <PetefromTn_> Should have these done by tomorrow.
[17:38:54] <PetefromTn_> Jeez man I HATE talking dog movies...
[17:39:11] <PetefromTn_> my kids LOVE watching these things and they just seem to get dumber as time goes on.
[17:39:34] <_methods> hahaha
[17:39:38] <PetefromTn_> right now I am enduring a santa pups marathon while I do my CAM work.
[17:39:46] <LeelooMinai> lol, I guess with those tables there is never a problem with positioning clamps:) http://www.t-slotblock.com/TSB%20VMC.html
[17:40:38] <_methods> wow.......
[17:40:40] <_methods> wtf
[17:40:49] <PetefromTn_> that is actually pretty cool
[17:41:03] <LeelooMinai> Mut be pita to keep clean though...
[17:41:12] <_methods> and to lock em all down
[17:41:20] <PetefromTn_> but I don't really see the difference between that and a myriad of tapped holes.
[17:41:52] <PetefromTn_> one nice thing about a tapped hole table is you can put setscrews in the holes you are not using and keep it KINDA clean..
[17:41:53] <_methods> that thing could pull up all over
[17:42:06] <_methods> and be uneven
[17:42:15] <_methods> i'd rather have a monolithic sub plate
[17:42:16] <PetefromTn_> says it is for VMC's
[17:42:35] <LeelooMinai> PetefromTn_: I saw some t-slot "covers" from aluminum too - same idea, to keep them clean if not used
[17:42:47] <PetefromTn_> sure
[17:43:34] <PetefromTn_> I guess what I am saying is that if it were MY machine.....I would just make an aluminum table with a myriad of tapped holes that accept the hold down clamps stud sizes and be done with it.
[17:44:13] <LeelooMinai> Yes, but I cannot make myriad tapped holes easily
[17:44:44] <PetefromTn_> its' too bad you are so far away I would do it for you on my VMC if you were closer
[17:44:58] <PetefromTn_> something like that would not take long at all and is simple to program.
[17:45:14] <LeelooMinai> I have to optimize everything for easy of making for now:)
[17:45:17] <PetefromTn_> besides if you can drill and screw down the plate you use the machine itself to drill the holes.
[17:45:54] <PetefromTn_> only downside of that is that you cannot add holes outside of the machining envelope which is often where you will want your clamps to go.
[17:46:01] <LeelooMinai> Yes, eventually, when I get the spindle or whatever it will be setup
[17:46:18] <LeelooMinai> I don't have this part yet
[17:54:01] <zeeshan|2> wow
[17:54:03] <zeeshan|2> 4 days
[17:54:05] <zeeshan|2> of talking about a table
[17:54:09] <zeeshan|2> :P
[17:54:52] <LeelooMinai> Sorry - I have to research everything - cannot afford to make a mistake:)
[17:54:56] <zeeshan|2> PetefromTn_: i totally agree with you
[17:55:00] <zeeshan|2> slots are pretty useless :p
[17:55:43] <zeeshan|2> for cnc machining that is
[17:58:08] <PetefromTn_> well yeah for instance my Cincinatti has large tee slots
[17:58:15] <PetefromTn_> but they are quite far apart
[17:58:20] * JT-Shop suspects an issue with the X axis home prox on the CHNC :( all the X offsets were off
[17:58:35] <zeeshan|2> almost always on jobshops where they are doing different stuff all the time
[17:58:38] <PetefromTn_> and I often have to screw around for awhile until I can figure out the best way to hold something on the table.
[17:58:42] <zeeshan|2> i see thoose huge steel tables
[17:58:46] <JT-Shop> none of my machines have the T slots in the right place lol
[17:58:47] <zeeshan|2> with a shitload of threaded holes in em
[17:59:16] <PetefromTn_> yeah they never seem to be exactly where you need them
[17:59:37] <PetefromTn_> whereas a nice table shot full of holes leaves you a bit more flexible.
[17:59:49] <zeeshan|2> who needs bolts right
[17:59:51] <PetefromTn_> that is if done correctly
[17:59:53] <zeeshan|2> just glue it onto the table!
[18:00:04] <PetefromTn_> carpet tape
[18:00:13] <PetefromTn_> done that several times
[18:00:14] <zeeshan|2> :)
[18:00:23] <PetefromTn_> works fine for light small flat plates
[18:01:48] <PetefromTn_> seems the same guy who I never heard of before today designed and built the NGCGUI as well as the latest attempt at a jog while paused feature for linuxCNC....
[18:02:09] <PetefromTn_> Dewey Garrett
[18:02:15] <Tom_itx> JT-Shop, gimme a bit and i'll have something for you to try
[18:03:49] * JT-Shop throws the towel into the ring
[18:04:13] <Tom_itx> just trying to get rid of the air cuts
[18:04:28] <JT-Shop> don't get much thread when you grab the clearance drill from the tap/drill rack
[18:04:39] <Tom_itx> heh
[18:05:50] <_methods> hehe loose fit
[18:08:44] <JT-Shop> yea pretty loose threads for sue
[18:08:47] <JT-Shop> sure
[18:09:08] <PetefromTn_> https://www.youtube.com/watch?v=InvVjA2k3fA interesting...
[18:09:11] <Rab> zeeshan|2, http://i.imgur.com/Y1x6XV0.jpg
[18:09:42] <Rab> zeeshan|2, I think the nut literally wasn't assembled correctly by whoever put the table together. It seems fine.
[18:09:43] <andypugh> Have a look at Dewey’s web site, he makes lovely things from wood.
[18:10:18] <Rab> I'll find out tonight.
[18:10:37] <zeeshan|2> nice
[18:10:40] <PetefromTn_> link?
[18:10:43] <zeeshan|2> such a high helix "D
[18:10:44] <zeeshan|2> :D
[18:12:14] <Rab> zeeshan|2, I cleaned off the nut and screw with alcohol as best as I could. Going to try to use white lithium grease. Worried about compatibility, but I have no idea what the old grease was. Looks like axle grease. :P
[18:12:18] <andypugh> PetefromTn_: Err.. http://www.deweygarrett.com
[18:13:15] <PetefromTn_> nice
[18:13:17] <Rab> The nut is some kind of plastic, but it's really pretty hard.
[18:13:21] <PetefromTn_> is that all CNC made?
[18:13:56] <andypugh> I don’t know.
[18:14:18] <zeeshan|2> rab for high velocity applications
[18:14:20] <zeeshan|2> they recommend oils
[18:14:29] <zeeshan|2> wait
[18:14:31] <zeeshan|2> i might have that backwards.
[18:14:48] <PetefromTn_> are you sure this is the same Dewey Garrett?
[18:15:08] <andypugh> Yes, very sure.
[18:15:09] <zeeshan|2> i take that back
[18:15:10] <zeeshan|2> it could be either.
[18:15:11] <zeeshan|2> :P
[18:15:24] <zeeshan|2> Now this is where problems can occur. In most cases, the grease used in electric motor bearings has a polyurea thickener. If a multiservice grease is being used in fan bearings, it will typically have a lithium-complex thickener. Mixing polyurea and lithium complex-based greases may cause bearing failures because some of these thickeners are incompatible.
[18:16:02] <PetefromTn_> https://www.youtube.com/watch?v=n2BBjQopArE Same guy
[18:16:30] <andypugh> PetefromTn_: If you scroll right down to the bottom of his home-page there is a video of linuxCNC in action.
[18:16:58] <Rab> zeeshan|2, those are very fast applications, though.
[18:17:01] <PetefromTn_> the one I just posted?
[18:18:21] <andypugh> PetefromTn_: As it happens, yes.
[18:18:51] <PetefromTn_> Creative and clever fellow it seems
[18:18:56] <PetefromTn_> beautiful work
[18:19:15] <PetefromTn_> I like that fourth axis machine he made
[18:19:28] <Rab> zeeshan|2, http://media.noria.com/sites/archive_images/Articles_200902_grease-compatibility-chart.gif
[18:19:30] <_methods> yeah does he have a build log for that?
[18:19:50] <zeeshan|2> what does i c b mean
[18:19:50] <Rab> zeeshan|2, I give up, just gonna slather on some lithium grease and call it good.
[18:19:59] <zeeshan|2> lithium grease works good in general :P
[18:20:11] <Rab> Incompatible/Compatible/Borderline
[18:20:19] <PetefromTn_> I like how he setup a copper strip and probed the side shape of that vase in it.
[18:20:29] <PetefromTn_> pretty inventive
[18:20:52] <PetefromTn_> from the looks of the video of the cutting apparently the depth worked very well.
[18:22:04] <PetefromTn_> https://www.youtube.com/watch?v=9A_YlKrPDuc&list=UUKND5TJ5n3EmG8qEIizLE9Q at 1:04 you can see the program setup. WOW that is impressive work
[18:22:31] <_Sync_> PetefromTn_: using a strip of shim stock is an old trick
[18:22:41] <PetefromTn_> yeah it is
[18:22:56] <PetefromTn_> but I never saw anyone use it to probe a curved surface like that
[18:22:57] <Rab> Copper tape might give you an even better profile.
[18:23:36] <PetefromTn_> I wonder how he was able to bend the contour picture around the waist of that curved shape so that it ends where it begins
[18:23:48] <andypugh> I am pretty sure that at 1:40 (ish) he is using the self-adhesive copper tape that is sold for tiffany-style stained glass work.
[18:24:10] <_Sync_> he probably just calculates it after the shape is measured
[18:24:20] <_Sync_> the plasma is not terribly difficult to generate
[18:25:03] <PetefromTn_> very interesting.
[18:25:15] <PetefromTn_> Altho at the end of the video you can see the whole finished part
[18:25:22] <PetefromTn_> while it is exceedingly beautiful
[18:25:35] <PetefromTn_> it is also much smaller than it appeared in the video to me
[18:26:04] <LeelooMinai> Do you have any MacGyver idea od cutting, say, 3/4 inch aluminum rod into segments with perfect parallel sides?
[18:26:40] <Rab> Looks like he uses a Foredom for the spindle, wonder how long that holds up.
[18:27:12] <_Sync_> does it really have to have really perfectly paralell sides?
[18:27:35] <LeelooMinai> As good as possible, yes
[18:27:44] <_Sync_> what for?
[18:28:04] <LeelooMinai> A kind of standoffs for my table
[18:28:17] <_Sync_> then it doesn't have to be as good as possible
[18:28:24] <_Sync_> just use a hacksaw
[18:28:26] <andypugh> I would part them off on a lathe.
[18:28:28] <LeelooMinai> 45 deg will not work:)
[18:28:51] <LeelooMinai> Yes, no, I am not doing it with a hacksaw
[18:29:05] <_Sync_> why not? that will be plenty good for a table leg
[18:29:16] <andypugh> But you ought to be able to square-off hacksawed sections with a counterboring bit.
[18:29:27] <Rab> LeelooMinai, use a mitre saw? The cut may not be precisely straight, but it should be reproducible from face to face.
[18:29:28] <LeelooMinai> _Sync_: cnc table, not coffee table...
[18:29:58] <_methods> cut it with a hacksaw and get out a file and make it square
[18:30:04] <_methods> first thing you learn
[18:30:10] <_methods> you can do a lot with a file
[18:30:22] <LeelooMinai> That sounds like a pretty bad plan... all that work
[18:30:31] <_methods> yes
[18:30:32] <_Sync_> then just use a lathe
[18:30:34] <PetefromTn_> take it to a friend with a decent lathe.
[18:30:35] <LeelooMinai> I will probably need a lot of them
[18:30:38] <_methods> it's called skill
[18:30:45] <_Sync_> why would you stand the table off
[18:31:24] <LeelooMinai> I am not standing the table off - I have a steel thin plate and the standoffs will be on it to support t-slot parts
[18:32:09] <LeelooMinai> And screwed from the bottom - so they better be flat
[18:32:17] <LeelooMinai> And parallel
[18:32:41] <_Sync_> that doesn't sound like a serious fixturing job
[18:32:55] <Rab> LeelooMinai, why round stock instead of square?
[18:33:17] <LeelooMinai> Well, can be square - I guess that does not matter, but same problem.
[18:33:40] <_Sync_> well, henn-egg-problem
[18:33:43] <Rab> Only if you try to use the ends, instead of orienting the chunks on their sides. ^_^
[18:33:45] <LeelooMinai> _Sync_: No idea what you mean by that? :)
[18:34:09] <_Sync_> I don't know why you would use round standoffs to fixture anything to a mill
[18:34:11] <LeelooMinai> Rab: Hey, that's a good idea:)
[18:34:23] <_Sync_> that doesn't sound like it would be a very rigid setup
[18:34:41] <LeelooMinai> _Sync_: It will be poured with epoxy granite
[18:35:09] <LeelooMinai> Rab: I dont know why I did not think about it
[18:35:15] <_Sync_> > polymer concrete
[18:35:17] <PetefromTn_> what will be epoxy granite/
[18:35:18] <_Sync_> hipster
[18:35:29] <_Sync_> what's your resin content
[18:35:42] <_Sync_> and your projected E module
[18:35:46] <LeelooMinai> Didn't I talk about it yesterday...
[18:36:06] <PetefromTn_> dunno maybe I missed it
[18:36:09] <LeelooMinai> It's like it's a new channel today suddnely and all those weird questions/ideas:)
[18:36:29] <PetefromTn_> Oh it's wierd alright
[18:36:47] <LeelooMinai> It will be polyester resin and granite pebbles and sand - nothing too involved
[18:36:48] <_Sync_> if you cast them in, be sure to use helicoils, but you usually don't want the parts to index off the cast supports
[18:36:57] <_Sync_> then you might just not do it
[18:37:27] <LeelooMinai> Well, not doing it will be not very productive:)
[18:37:35] <PetefromTn_> you will probably have more money in a table made like that then if you just bought some mic6 plate and had it drilled and tapped heh
[18:37:53] <LeelooMinai> Not according to my calculations
[18:37:55] <_Sync_> because if you don't use proper filler you could just cast it out of resin completely
[18:38:13] <LeelooMinai> I just need 1 litre resin, which is $15 and pebbles and sand, which will be additional $15
[18:38:40] <LeelooMinai> mnic6 plate quoted to me was $888...
[18:38:50] <LeelooMinai> I see some price difference there
[18:38:52] <PetefromTn_> thats insane price
[18:38:54] <_Sync_> cast a test piece and measure the e mod
[18:38:57] <_Sync_> and be amazed
[18:39:09] <_Sync_> I just ordered a granite surface plate after that
[18:39:42] <LeelooMinai> _Sync_: I don;t know what you are talking about - I will have steel plate underneath it, steel reinforcments embedded, and it all will be fine for my cnc
[18:41:16] <LeelooMinai> PetefromTn_: Well, that's the price I got from metalsupermarkets here in my city
[18:41:36] <LeelooMinai> Even half of that is too much
[18:41:38] <_Sync_> if you say so, in my experience if you don't use geometry optimized filler sands it's not worth it
[18:41:54] <Tom_L> JT-Shop you still around?
[18:42:56] <PetefromTn_> Well I dunno what to say that price is ludicrous
[18:43:08] <_Sync_> yeah, that's pretty steep
[18:44:14] <PetefromTn_> http://www.ebay.com/itm/MIC-6-CAST-TOOLING-ALUMINUM-PLATE-3-4-x-24-x-24-/261160112043?pt=LH_DefaultDomain_0&hash=item3cce5b0fab
[18:44:30] <PetefromTn_> that is just a quick ebay search and frankly that price sucks
[18:45:15] <PetefromTn_> how did you get the material to make the rest of the machine? It's all heavy aluminum plate too isn't it?
[18:46:07] <LeelooMinai> PetefromTn_: Yes, that's US prica without shipping - I am in Canada.
[18:46:12] <LeelooMinai> price*
[18:46:22] <PetefromTn_> yup it is
[18:46:32] <PetefromTn_> surely there are suppliers in canuk land too no?
[18:46:48] <LeelooMinai> PetefromTn_: Only some parts are plate, the rest are tubes filled with sand and just wide flat bars for gantry
[18:47:14] <PetefromTn_> ok
[18:47:47] <LeelooMinai> I just used plates for z-be and small xy table bed, because otehrwise they are too expensive
[18:48:36] <PetefromTn_> well I dunno what else to say.. Good luck with whatever you decide to do.
[18:48:45] <_methods> hehe
[18:49:25] <LeelooMinai> ok, if you don't believe me:) http://i.imgur.com/Bd47EL4.png
[18:49:33] <LeelooMinai> That's only half inch and 16 by 16
[18:50:47] <_methods> hahahahhah i need to start selling aluminum in canada
[18:51:11] <PetefromTn_> Nobody said they did not believe you.
[18:51:31] <PetefromTn_> I am certain there are nefarious assholes taking advantage of people even in Canada
[18:51:34] <_methods> 1/2" x 16 x 16 for $900 that's insane
[18:51:52] <_methods> that's like home depot metal prices
[18:52:10] <PetefromTn_> Hell not even HD would try that nonsense
[18:52:42] <SpeedEvil> Maybe precision milled, TiN coated, and signed by beyonce.
[18:52:44] <LeelooMinai> Well, and you wonder why I am so obsessed with making it in some cheap way, even if a bit involved
[18:52:50] <PetefromTn_> sounds like a GO AWAY we don't want to be bothered with your small time parts nonsense to me...
[18:53:28] <LeelooMinai> They are supposed to deal with small orders
[18:53:40] <LeelooMinai> At least they advertise this way too
[18:53:46] <PetefromTn_> holy smokes...
[18:53:55] <_methods> http://www.mcmaster.com/#86825k827/=ur64f7
[18:54:04] <_methods> $124 from mcmaster lol
[18:54:12] <_methods> and that's probably %50 too high
[18:54:21] <PetefromTn_> you could buy a whole sheet for less than that...
[18:54:21] <_methods> sorry $135
[18:54:37] <SpeedEvil> PetefromTn_: whole sheet and a saw
[18:55:00] <_methods> no doubt
[18:55:17] <_methods> and a case of beer to drink while you cut it out
[18:55:29] <PetefromTn_> and pay for a cheerleader
[18:55:35] <PetefromTn_> with huge titties LOL
[18:55:45] <_methods> that taste like vanilla ice cream
[18:55:54] <PetefromTn_> ROFL
[18:55:58] <SpeedEvil> Huge titties mean she can't see where to cut the metal properly
[18:56:16] <PetefromTn_> Oh yeah she needs to be doing the cutting that is perfect!
[18:57:15] <PetefromTn_> but I digress.......the price is high....ahem
[18:58:30] * SpeedEvil wonders again how much shipping a large parcel from china would be.
[19:00:09] * PetefromTn_ didn't even know mcmaster carr sold Mic6 plate and tips his hat to methods for pointing out the obvious...!!
[19:00:31] <zeeshan|2> _methods dont sell to canada
[19:00:35] <zeeshan|2> we get metal cheap here :)
[19:00:48] <zeeshan|2> theres like 3 extruders in my town
[19:00:55] <zeeshan|2> and a couple of foundrys
[19:01:45] <SpeedEvil> yeah - you just dip a ladle into the runoff of 6061 cascading down the street.
[19:01:51] <_methods> yeah mcmaster will sell anything........for a price
[19:01:56] <_methods> not as bad as home depot
[19:01:58] <_methods> but close
[19:02:00] <zeeshan|2> mcmaster doesnt ship to residential addresses in canada
[19:02:05] <zeeshan|2> only universities and businesses
[19:02:26] <zeeshan|2> you can get that mic-6 plate locally 24x24x1/2" for $120 bux
[19:02:38] <_methods> there ya have it
[19:02:39] <PetefromTn_> there ya go...
[19:02:59] <zeeshan|2> LeelooMinai only shops at home depot
[19:03:02] <zeeshan|2> and metal supermarkets
[19:03:04] <_methods> or you can go find some sand and epoxy and make a fu mess lol
[19:03:08] <PetefromTn_> buy some for Leeloo and ship it to her house so we can see this machine running finally LOL
[19:03:14] <_methods> s/fu/fun
[19:04:57] <roycroft> do any of you use outdoor carpet to line the drawers of your toolchests?
[19:05:18] <Tom_itx> no i use rubber mat
[19:05:50] <roycroft> my kennedy uppers have felt liners
[19:06:04] <Tom_itx> mine did too
[19:06:06] <_methods> felt
[19:06:14] <roycroft> i was thinking about doing that for my kennedy roll-away, but then i started thinking about using outdoor carpet
[19:06:21] <_methods> i keep dessicant packs in mine too
[19:06:28] <roycroft> that's a good idea
[19:06:41] <roycroft> dessicant packs and liberal use of tool oil
[19:06:45] <_methods> yeah i just throw a dessicant pack i every drawer
[19:06:54] <_methods> probably overkill
[19:06:59] <PetefromTn_> I had outdoor carpet in my old tall toolbox
[19:07:01] <_methods> but i don't want rust on my mic's
[19:07:29] <SpeedEvil> ~10C of heater will help a _lot_
[19:07:36] <roycroft> any problems with rust with that, petefromtn_?
[19:08:37] <PetefromTn_> no not really but shit and chips does get stuck in the nap
[19:08:51] <roycroft> i close the drawers when i'm operating machinery :P
[19:08:55] <SpeedEvil> I assume that there is some good reason not to use extruded sheet, ground flat?
[19:09:22] <roycroft> i have some of the perforated rubber mat in one of my roll-aways
[19:09:38] <roycroft> and some tools got little diamond shaped rust spots on the lower side one winter
[19:09:46] <roycroft> i did not like that
[19:10:10] <roycroft> i have some cheap rubber liners from hf in the kennedy roll-away right now
[19:10:18] <roycroft> but they're sticky, curling up, and smell chinese
[19:10:20] <roycroft> i want them gone
[19:10:37] <roycroft> i might try outdoor carpet for a season
[19:10:46] <roycroft> not glued in - just cut and set in place
[19:12:10] <_methods> cork sheet is nice too
[19:12:19] <roycroft> i've considered that
[19:12:32] <_methods> i have that in one of my boxes
[19:12:46] <roycroft> i might look at those 12" square cork tiles
[19:12:56] <roycroft> i'm not sure i can source cork sheet locally
[19:12:59] <roycroft> but the tiles are readily available
[19:13:14] <roycroft> would the cork absorb oil though?
[19:14:36] <_methods> bah helps if you have the right board selected when you try to push program to arduino lol
[19:16:10] <SpeedEvil> http://www.ebay.co.uk/itm/All-Polished-Granite-Slabs-Tablets-Surface-plates-/261093511474?pt=UK_Measuring_Tools_Levels&var=&hash=item3cca62d132 Impressive postage.
[19:16:34] <SpeedEvil> 6.99 for a 24*32*2" plate. Of course there is the issue if by 'surface plate' they mean 'we saw other granite called surface plates, and ours looks just like it'
[19:17:12] <roycroft> if i were in the uk i would jump at that
[19:17:28] <roycroft> usually, chinese surface plates cost 2x as much to ship as the purchase price
[19:18:21] <SpeedEvil> yeah - It literally can't be fucked up enough to not be a useful machine base
[19:20:33] <tjtr33> haha i figured it out ICB is I = incompatible C = compatible & B = Both :)
[19:21:30] <SpeedEvil> For some strange reason several feet by several feet cast iron surface plates are cheap :)
[19:21:42] <SpeedEvil> 'please take this away'
[19:26:33] <tjtr33> http://goo.gl/Tm7cRF 13 foot x3 foot
[19:27:35] <PetefromTn_> jeez that must be one heavy bitch
[19:30:32] <XXCoder> SpeedEvil: can cnc cut it lol
[19:30:54] <tjtr33> there was another in Rockford IL for a lot less , and a lot bigger. the weeds growing around it stated something
[19:31:04] <XXCoder> tjtr33: dang. make it into cnc table. really long and biug one lol
[19:31:22] <tjtr33> was off a shaper i think
[19:32:12] <SpeedEvil> that's what - 7 tons?
[19:33:03] <SpeedEvil> Oh - I forgot to subtract the weight saving from the t-slots :)
[19:33:27] <XXCoder> probably saved so much. itt would be 6.9 tons? ;)
[19:37:31] <PetefromTn_> speaking of surface plates..
[19:38:04] <PetefromTn_> How cool would it be to buy an old huge plate and make it into one of those Datron style CNC mills....
[19:39:11] <PetefromTn_> I also see a lot of old used CMM machined that would probably be the perfect platform to build something like that on. At least the base might be.
[19:40:08] <XXCoder> any good site explaining what datron is
[19:40:16] <PetefromTn_> http://asheville.craigslist.org/tld/4714307837.html
[19:40:43] <XXCoder> ahh
[19:40:45] <PetefromTn_> https://www.youtube.com/watch?v=_PC9ezN6cno
[19:41:39] <XXCoder> interesting
[19:41:49] <PetefromTn_> FAST
[19:42:16] <_methods> yeah we made a shop floor inspectio plate from an old dead cmm
[19:42:32] <PetefromTn_> you can sometimes get them pretty damn cheap
[19:42:58] <XXCoder> so it figures where stock is then make part?
[19:43:05] <PetefromTn_> If you were willing to drill and epoxy inserts into it you could probably add some linear guideways and build something really cool
[19:45:05] <_methods> https://www.youtube.com/watch?v=gr3RM8yCfUg
[19:47:48] <_methods> i'd love to have an applications job so i could do that all day lol
[19:49:04] <_methods> make silly parts to show off machines all day
[19:49:17] <XXCoder> heh fun
[19:49:22] <PetefromTn_> jeez that is sexy
[19:49:33] <XXCoder> tmio
[19:49:41] <XXCoder> heh
[19:50:13] <_methods> no place i've ever worked at could afford an okuma
[19:50:19] <_methods> one day i'll get to have sex with one
[19:50:38] <XXCoder> lol
[19:51:14] <_methods> this VTM is crazy
[19:51:15] <PetefromTn_> and to think I would be happy with my VMC and my little CNC lathe here
[19:51:16] <_methods> https://www.youtube.com/watch?v=Ro6T04qNsVo
[19:51:28] <XXCoder> funny thing
[19:51:40] <XXCoder> its far from most riciously expensive cnc video I ever seen
[19:51:54] <XXCoder> no, that honor fgoes to one that made all alum bicycle helmet
[19:53:50] <XXCoder> https://www.youtube.com/watch?v=PbdgUBwKcsg
[19:54:57] <LeelooMinai> Not very practical helmet:)
[19:55:04] <XXCoder> yeah
[19:55:13] <XXCoder> but damn look at that cnc go
[20:11:25] <_methods> hehe dasfasdf
[20:19:33] <_methods> wow laptop went bonkers
[20:21:07] <_methods> xmas lights almost set up just need to get the wifi and web app done and a couple more 5m strips
[20:21:10] <_methods> https://www.dropbox.com/s/3xg64dg8r37dliy/2014-11-26%2001.50.38.mp4?dl=0
[20:21:44] <_methods> gotta make the enclosure and the pcb for it all too
[20:21:53] <_methods> running out of time before tree time
[20:22:14] <PetefromTn_> Hey man that is freakin cool!
[20:22:27] <_methods> yeah they are great fun
[20:23:04] <_methods> i need to make some more patterns
[20:23:49] <PetefromTn_> how are you controlling that?
[20:23:54] <_methods> arduino
[20:24:12] <_methods> i was using a mega for that but i'm gonna use a mini for the final thing
[20:24:59] <PetefromTn_> can you inline many 5m strips or is there load problems?
[20:25:29] <_methods> you might need to drop power supplies in there
[20:25:46] <_methods> that was 1 5m strip running off a 5v 5a power supply
[20:25:53] <_methods> 300 leds
[20:26:25] <PetefromTn_> neat
[20:27:09] <_methods> yeah you can get a 5m strip for like $50 or so
[20:27:45] <PetefromTn_> I know just bought that kit
[20:27:57] <PetefromTn_> should be here by the 29th or so apparently
[20:28:16] <_methods> they're cool
[20:28:33] <_methods> i was never much of a blinkie light person
[20:28:45] <_methods> but those things kinda got me interested
[20:31:39] <jfigie> Is there an easy way to change the direction of an axis? Instead of x+ moving the table to the left I want X+ to move the table to the right.
[20:32:16] <_methods> yeah change the x in your settings
[20:32:22] <cradek> sure but you don't really want that. x+ moves the TOOL right (table left)
[20:32:38] <pfred1> hey cradek!
[20:32:42] <cradek> assuming you're talking about a normal vertical mill
[20:32:48] <cradek> pfred1: uh-oh
[20:32:59] <pfred1> cradek I'm using your Debian image
[20:33:04] <cradek> yay
[20:33:06] <pfred1> it's all right
[20:33:16] <pfred1> saved me a lot of time setting stuff up
[20:33:25] <pfred1> so thanks for that
[20:33:28] <cradek> welcome
[20:33:51] <pfred1> you even setup some stuff that I wouldn't have like the desktop icon and the menu entries
[20:33:57] <pfred1> they're nice
[20:34:11] <pfred1> though i do have to build a non-pae kernel one of these days
[20:34:14] <cradek> that's just in the linuxcnc package
[20:34:27] <pfred1> hmmm I never got them building from source
[20:34:28] <cradek> why?
[20:34:35] <pfred1> I just don't like pae
[20:34:39] <pfred1> too much overhead
[20:34:49] <cradek> whatevs
[20:34:51] <pfred1> I don't really need that RAM anyways
[20:35:14] <pfred1> but the latency is fine it isn't an issue
[20:35:15] <cradek> I think you'll lose the ability to run the released versions if you do that
[20:35:22] <pfred1> hmm
[20:35:28] <cradek> released packages, I mean
[20:35:42] <pfred1> should just lose RAM past about 3.5GB
[20:35:48] <pfred1> that's all pae does
[20:36:05] <cradek> yeah I know what pae is
[20:36:46] <pfred1> in any event I've bigger fish to fry right now so it is nothing I've plans on doing anytime too soon
[20:37:17] <pfred1> one bizarre thing I've noticed is that PC seems to lose my add on parallel port card from time, to time but I think it is the PC not software doing that
[20:37:53] <jfigie> yes I just want to change the direction of x temporarily. X settings?
[20:38:18] <jfigie> I am not sure what you mean by x settings
[20:38:22] <pfred1> jfigie x is ambigious what x are you referring to?
[20:38:39] <jfigie> x axis on a milling machine
[20:38:55] <jfigie> I want to make it run backwards
[20:38:58] <pfred1> that'd be weird I suggest you just get used to the direction that it goes in now
[20:39:31] <jfigie> I am used to the direction I just want to test my motor because it runs smooth in one direction but not the other
[20:39:51] <pfred1> doesn't sound like softweare to me
[20:39:54] <jfigie> I want to reverse the wires on the motor and tach to see if the direction of the problem changes
[20:40:11] <pfred1> servo?
[20:40:11] <Tom_itx> just change the scale
[20:40:29] <jfigie> is this in the ini file?
[20:40:32] <Tom_itx> + to - or vise versa
[20:41:44] <_methods> invert x direction in the parallel port setup
[20:42:45] <_methods> many ways to do what you want to do
[20:47:18] <jfigie> Ok I think you are telling me to change the sign in the "OUTPUT_SCALE" in the .INI file for AXIS_0, where axis 0 is the x in my case.
[20:47:26] <jfigie> Thanks
[20:48:17] <cradek> it's not a software problem - your test won't change what the hardware does
[20:49:38] <pfred1> I've been having some serious X axis hardware issues here
[20:49:56] <pfred1> I did not make my machine nearly stiff enough there at all
[20:50:09] * pfred1 has been addressing that
[20:50:39] <pfred1> one side stalled and the other kept on going and the whole machine bent up like a diamond on me
[20:50:48] <pfred1> I was like doh!
[20:51:36] <pfred1> I'm going to make some brackets out of heavy weight angle and see if that does the trick
[20:51:54] <pfred1> see if it can bend steel 3/8s of an inch thick
[20:52:10] <_methods> what size steppers?
[20:52:13] * pfred1 is betting it can't
[20:52:19] <pfred1> only 200 ox/in
[20:52:22] <pfred1> oz
[20:52:41] <pfred1> I calculated the force with the threaded rod once and it isn't trivial
[20:52:49] <pfred1> something like 4 tons?
[20:52:57] <_methods> threaded rod?
[20:53:04] <pfred1> my lead screws
[20:53:16] <pfred1> they are 1/2 x 10 TPI acme
[20:53:59] <_methods> over what distance?
[20:54:11] <pfred1> what difference does distance make?
[20:54:13] <cradek> jfigie: sounds like dodgy motor brushes or tach (probably tach)
[20:54:15] <pfred1> it is a pull
[20:54:16] <_methods> alot
[20:54:43] <pfred1> the whole machine is about 3 feet wide in that direction
[20:54:56] <jfigie> ok maybe i need to rethink this. I agree this is a hardware problem so it is either the drive, the motor or the tach. Lets say the motor runs bad in the clockwise dir. If is reverse the motor leads and tach leads and the motor still runs bad clockwise then its the motor or tach otherwise its the drive.
[20:55:20] <cradek> jfigie: I have spun a tach in a drill press and scoped the output to see a dead spot
[20:55:40] <jfigie> I like that idea
[20:55:59] <cradek> you might be able to see the problem with it still in the machine
[20:56:04] <pfred1> yeah without a scope someone might as well be blind working on a lot of electronics
[20:56:08] <tjtr33> jfigie, maybe use a battery box at the drive to simplify the problem ( 2 9V batteries and a pot, the output is +/- 9V )
[20:56:16] <cradek> does it go bang bang bang once a revolution? you can probably measure it in halscope
[20:56:20] <tjtr33> no linuxcnc involved
[20:56:37] <cradek> what's it sound/feel like
[20:56:43] <jfigie> I can see the problem on hal scope looking at the error signal when I move + or -
[20:56:46] <pfred1> make a video@!
[20:56:55] <jfigie> in one direction the signal is flat.
[20:56:56] <cradek> share that pic
[20:57:14] <jfigie> the bad dir the signal has an oscillation
[20:57:20] <pfred1> my camera sucks for making videos i made one of my machine but it looks like a cartoon
[20:57:37] <jfigie> more like a sawtooth shape
[20:59:13] <jfigie> I can share but it will be a while. The machine is out in shop and turned off right now.
[20:59:37] <cradek> ah, no pressure, that leads to anxiety problems
[21:00:14] <_methods> and scrap
[21:24:55] <pfred1> that's what i love about machines they can alqways wait
[21:25:17] <pfred1> I didn't get much done on mine today
[21:25:25] <pfred1> I had other things to do
[21:25:57] <pfred1> maybe by Christmas I'll have it running again?
[21:26:03] <pfred1> ho ho ho!
[21:36:51] * LeelooMinai modified her table idea again
[21:37:41] <Connor_mill> okay pcw_home or anyone else.. what's the command to flash the 5i25? need to load it up with 5i25_7i76x2r.xml file.
[21:37:42] <LeelooMinai> I think I will go full MacGyver on this one:)
[21:37:52] <XXCoder> LeelooMinai: using unobtainable for table? heh
[21:38:11] <pfred1> if there's no baling wire it just isn't DIY CNC
[21:38:19] <XXCoder> duck tape
[21:38:33] <XXCoder> just use wood slab and tape the stock down lol
[21:38:34] <pfred1> I used some gorilla tape does that count?
[21:38:51] <XXCoder> pfred1: I use it often at work because vaccum hold sucks
[21:39:04] <pfred1> I meant to make my machine with
[21:39:14] <LeelooMinai> Well, I calculated cost of matierals for this type of configuration: http://i.imgur.com/ol7aNbx.png
[21:39:14] <XXCoder> oh lol
[21:39:32] <LeelooMinai> That is, for the t-slot type, and decided it's too much work and too much cost
[21:39:48] <pfred1> here's parts of my machine after I repainted it http://i.imgur.com/YjR9k6v.jpg
[21:39:58] <pfred1> and added steel rails
[21:40:23] <pfred1> it is the holey wonder
[21:40:36] <LeelooMinai> So, that leaves me with staggered holes, or just say 3/8 nuts so I can use that machinist clamping set in them, say every 1 inch
[21:40:52] <XXCoder> LeelooMinai: easy
[21:40:58] <XXCoder> use cnc itself to make holes
[21:41:09] <LeelooMinai> However, that would mean I would have to preset some crazy number of holes first
[21:41:23] <LeelooMinai> XXCoder: I am making it, so you know, chicken-egg:)
[21:41:32] <roycroft> for your initial table, get some 1/2" plate, mount it on the machine, and drill/tap 3/8" holes for the clamping system
[21:41:32] <XXCoder> I saw one guide where guy building cnc literally cuts table with nesscary stuff with cnc
[21:41:53] <XXCoder> LeelooMinai: yeah but since table works you can just cut it and stuff with functional cnc
[21:42:22] <LeelooMinai> Then I had this Eureka - I will just buy peg board and use it as the base of my epoxy cast and just bolt the nuts thhrough the pegboard holes:)
[21:42:25] <XXCoder> so table basically is last peice to be complete
[21:42:56] <LeelooMinai> Minimal cost and no drilling necessary
[21:43:16] <LeelooMinai> I will just need a lot of nuts and bolts
[21:43:17] <XXCoder> Yeah but then doing it with cnc also basically mean no drilling manually too
[21:43:29] <LeelooMinai> XXCoder: I don't even have a spindle yet
[21:43:45] <XXCoder> yeah just wait on table till basically everything else is done
[21:44:05] <XXCoder> hell you can even make nut holes for other side
[21:44:13] <XXCoder> then flip it and drill holes for it
[21:44:25] <XXCoder> boom bunch of holes with nuts under all of em
[21:45:09] <LeelooMinai> I want to make table first thoug as I don't know when I will be able to afford spindle, vfd, etc.
[21:45:33] <LeelooMinai> And with the table I can try some other things - like pcb routing with rotary tool
[21:46:08] <XXCoder> ahh hmm guess so
[21:46:19] <XXCoder> Im sure you can do same with rotary tool
[21:46:20] <LeelooMinai> I think it's worth a try - I don't think I can reduce the cost any more
[21:46:24] <XXCoder> I plan to use router for mine
[21:46:39] <XXCoder> one thing that sucks is min rpm 8,000
[21:46:47] <XXCoder> and not computer controlled rpm
[21:47:48] <LeelooMinai> I wonder how they make holes in pegboards - if they drill them individualy on a cnc or they have something that makes them all at once
[21:47:57] <XXCoder> nah
[21:48:01] <XXCoder> press most likely
[21:48:10] <XXCoder> rolling board boom boom booom so on
[21:48:17] <LeelooMinai> But I bet they are pretty precisely spaced
[21:48:26] <XXCoder> yeah single plate for one row
[21:48:28] <LeelooMinai> So if I use them for a template I should get nice frid
[21:48:32] <LeelooMinai> grid*
[21:48:46] <pfred1> I've seen a machine that gang drills the panels for tractor trailers
[21:48:54] <pfred1> lots of pulleys
[21:49:25] <LeelooMinai> XXCoder: So like a roller with pins on it?
[21:49:51] <XXCoder> dont think so
[21:49:56] <XXCoder> more like just press
[21:50:00] <LeelooMinai> I mean like a dough roller with pins
[21:50:25] <XXCoder> HMMMM
[21:50:27] <XXCoder> http://diamondlifegear.com/pegboardsystems.htm?gclid=CPC3p6-ql8ICFUxsfgodg6kAbg
[21:50:28] <LeelooMinai> Press that does the whole grid in both dimensions?
[21:50:38] <XXCoder> metal, plastic and hardboard
[21:50:51] <XXCoder> row a time seems more likely
[21:51:22] <LeelooMinai> I think normal one from mdf will do for me
[21:52:20] <pfred1> my machine is sort of free standing so it sits on any table
[21:52:21] <LeelooMinai> I fill fasten the nuts from one side and put bolts on the other side, so that the nuts cannot be pulled out from the epoxy/granite
[21:52:44] <LeelooMinai> And later I will remove the fastening bolts
[21:52:47] <pfred1> theoretically I guess it could machine a ceiling?
[21:53:27] <pfred1> I designed it to be onmidirectional
[21:53:40] <XXCoder> 3 axis or more?
[21:53:45] <pfred1> just 3
[21:54:12] <pfred1> but the way the linears work and everything it is all symetrical
[21:54:52] <pfred1> the only up down oriented thing is the tool in the Z axis
[21:55:05] <XXCoder> nice
[21:55:13] <XXCoder> dunno who would wanna ceiling mill but cool
[21:55:20] <LeelooMinai> Hmm a 20 by 20 grid is 400 nuts - that's pretty nuts
[21:55:31] <pfred1> well I could stand it on its side to save space
[21:55:41] <LeelooMinai> Maybe I should make the grid more sparse:)
[21:55:53] <pfred1> might make loading and unloading it easier too?
[21:55:55] <XXCoder> design so nuts is movable
[21:56:00] <XXCoder> removable too
[21:56:07] <XXCoder> so you can use just few as needed
[21:56:16] <XXCoder> also makes em replacable in case of screwups
[21:56:27] <LeelooMinai> They will be embeded in the resin - I cannot make them movable
[21:56:48] <pfred1> you'll only end up using like 4 of them
[21:57:01] <pfred1> that is how things like that often go
[21:57:21] <pfred1> but the others will look nice i suppose
[21:57:37] <LeelooMinai> Well, maybe not 4, but a subset, yes, but if I need some in places they should kind of be there
[21:57:59] <LeelooMinai> I cannot predict what and where I will clamp
[21:58:14] <pfred1> maybe not but patterns will emerge
[21:58:43] <pfred1> you'll get in the habit of doingthings a certain way and that'll be that
[21:58:55] <LeelooMinai> I don't mind screwing 400 nuts since the holes in the pegboard are already there, but I wonder if it will not become too costly
[21:59:18] <XXCoder> what kinda stuff you making?
[21:59:39] <LeelooMinai> I am not making yet anything - just finishing my cnc "platform"
[21:59:58] <LeelooMinai> That is table - with very limited budget
[22:00:27] <XXCoder> what size your grid? whats closest distance nut to nut?
[22:00:51] <LeelooMinai> Table is 21 x 21 or so - pegboards seem to have 1 inch grid
[22:01:03] <XXCoder> each one inch hmm
[22:01:15] <XXCoder> wonder if can do 2 in
[22:01:31] <XXCoder> using around 2 inch clamps
[22:01:48] <LeelooMinai> That's an option - or I could do 1 inch in the middle and 2 on the borders
[22:02:07] <XXCoder> thats idea
[22:02:24] <XXCoder> shagger outside "square"
[22:02:30] <XXCoder> so theres always some hole near
[22:02:35] <LeelooMinai> Yes
[22:02:58] <LeelooMinai> I will do test on a small patch, say 4 by 4 inches first - I wonder how it will turn out
[22:04:50] <pfred1> sounds like a grand plan for al imited budget to me
[22:04:54] <jfigie> cradek I think my problem is the motor or tach like you suggested. http://imagebin.ca/v/1iWkM2lwHjly is running at 1440 mm/min = 24mm/sec with 2.5mm / motor rev = 9.6 Hz http://imagebin.ca/v/1iWl0MC0JOgE is 2880 mm/min and the frequency doubles. frequency is the same as the motor shaft.
[22:06:01] <cradek> tach!!
[22:06:38] <jfigie> thanks
[22:06:39] <cradek> scope it, and see if it makes the same voltage at the same speed in both directions
[22:07:10] <pcw_home> dirty tach brushes?
[22:07:13] <cradek> be very careful hooking up your scope - use both probes and difference mode - do not assume you can ground one side of the tach
[22:07:17] <jfigie> http://imagebin.ca/v/1iWlVHF6G4AN is 2880 mm/min in other dir
[22:08:00] <cradek> sometimes you can rotate the base of the tach to adjust it so it's the same in both directions
[22:09:04] <jfigie> ok this is a SEM motor with heidenhain encoder. I will look at it tomorrow. Thanks for your help.
[22:09:23] <cradek> please report back, it's an interesting problem
[22:09:31] <jfigie> will do
[22:10:24] <jfigie> but I think I would also like to get rid of the old bosh drives. they use SCRs !
[22:11:50] <jfigie> I think they are kind of slow having a PWM frequency of 120Hz (I think)
[22:20:05] <pfred1> what is wrong with SCR?
[22:22:11] <tjtr33> both motor and tach have brushes, check the motor brushes ( remove, look for wear, clean rotor, blow out w compressed air etc) for tach, well they can be extremely tiny brushes, same is needed but if it looks to delicate, DONT ) also check connections to brushes ( often female spade )
[22:23:13] <skunkworks> the servos we are using on the K&T were originally run with SCR drives
[22:27:22] <tjtr33> the error was jitter on pid.0.error, and was directional ... is a brush so loose/worn that it cocks? and the end wear shape makes it hop?
[22:28:35] * skunkworks has never had good luck with tach..s
[22:29:17] <pfred1> scrs are usually pretty reliable
[22:29:39] <tjtr33> if its an SEM motor he oughtta be able to find the orig brush info, and check the length
[22:30:52] <tjtr33> and if he can spin the motor at a constant speed, he oughtta get a constant dc tacho voltage, not ripply like his Hal scope pix
[22:31:55] <PetefromTn_> Well I am scratching a line in the sand here guys....LOL
[22:32:13] <tjtr33> fight fight
[22:32:15] <PetefromTn_> I am gonna get the new control panel designed for the Cincinatti over the weekend or bust
[22:32:40] <Tom_itx> designed or built?
[22:32:41] <PetefromTn_> If I don't do it, it's not gonna design itself right.
[22:33:00] <PetefromTn_> well right now designed because I need to figure out what switches and stuff to order etc.
[22:33:26] <PetefromTn_> I have some leftover half inch plate 6061 that I used for a fixture I can do it out of.
[22:34:08] <PetefromTn_> I want to get the rotary selectors like we were discussing for axes selection and step selections
[22:34:14] <cradek> yikes, 1/8 is plenty
[22:34:17] <PetefromTn_> Started drawing it a bit ago.
[22:34:24] <PetefromTn_> Yeah I know but it is all I have
[22:34:26] <tjtr33> 1/2 is bezel not panel
[22:34:40] <PetefromTn_> unless I want to buy something else
[22:34:40] <cradek> and 5052 will stay shiny better
[22:34:58] <PetefromTn_> it's gonna be brushed finished
[22:35:08] <PetefromTn_> might even have it anodized or something
[22:35:25] <PetefromTn_> I should clarify
[22:35:34] <PetefromTn_> the machine already has a panel
[22:36:02] <PetefromTn_> the panel currently has the limited number of buttons I have, the MPG, and the display in it.
[22:36:21] <PetefromTn_> This panel will be JUST for the buttons and MPG and mount to the main panel under the display
[22:37:03] <tjtr33> 19" 4U panel 20$ black anodized
[22:38:13] <tjtr33> http://goo.gl/M57t9U
[22:40:22] <PetefromTn_> http://i150.photobucket.com/albums/s83/matospeter/Cincinatti%20Arrow%20500%20Retrofit/IMG_20130508_225541_zpsd7988425.jpg
[22:40:31] <PetefromTn_> This is what the panel looks like now
[22:40:59] <PetefromTn_> rather that is what It looked like a couple months ago anyways LOL
[22:41:10] <tjtr33> pretty, nice work
[22:41:13] <PetefromTn_> so I am going to make a panel to go under the display
[22:41:33] <PetefromTn_> that occupies the area inside the black bezel
[22:41:36] <PetefromTn_> thanks
[22:41:43] <zeeshan|2> PetefromTn_:
[22:41:45] <PetefromTn_> its not much but it sure works nice
[22:41:46] <zeeshan|2> thank y ou for posting a non shitty pic
[22:41:48] <zeeshan|2> !!! :D
[22:41:53] <zeeshan|2> thats the first time ive seen your machine :D
[22:41:55] <PetefromTn_> what do you mean
[22:42:04] <zeeshan|2> your pics are really blurry usually :{
[22:42:09] <zeeshan|2> and grainey!!
[22:42:22] <zeeshan|2> http://s150.photobucket.com/user/matospeter/media/Cincinatti%20Arrow%20500%20Retrofit/IMG_20130701_171050_zpsb07a216a.jpg.html
[22:42:23] <zeeshan|2> like that
[22:42:23] <zeeshan|2> haha
[22:42:27] <PetefromTn_> that's because all of the other pics I have posted have been from years ago
[22:42:33] <zeeshan|2> oh
[22:42:42] <zeeshan|2> your coolant
[22:42:44] <zeeshan|2> is really blue!
[22:42:47] <PetefromTn_> actually that pic is not that old
[22:43:03] <PetefromTn_> just used my old cellphone to take it which had a shitty camera
[22:43:05] <tjtr33> got 19" ? thats an industry std for control cabinets racks
[22:43:09] <zeeshan|2> PetefromTn_:
[22:43:12] <zeeshan|2> your machine is really CLEAN
[22:43:16] <PetefromTn_> no
[22:43:27] <PetefromTn_> the area I am working with is 9.25x15.5
[22:43:29] <PetefromTn_> inches
[22:43:41] <PetefromTn_> thanks man I spent a LOT of time cleaning that thing
[22:43:45] <PetefromTn_> it was FILTHY
[22:43:52] <PetefromTn_> much like my new CNC lathe
[22:44:06] <tjtr33> cut off 3.5 ;) 20$ is cheaper than your 1/2 plate
[22:44:06] <PetefromTn_> actually the Cincinatti was dirtier than the lathe initially.
[22:44:24] <PetefromTn_> yeah but I already have the plate here LOL
[22:44:29] <PetefromTn_> so it's freeeee
[22:44:46] <PetefromTn_> somebody else already paid for it :D

[22:44:58] <zeeshan|2> i see what you mean about the t-slots now
[22:45:32] <PetefromTn_> yeah they are not the best
[22:45:44] <PetefromTn_> but so far I have made them work for everything somehow
[22:46:07] * zeeshan|2 is going
[22:46:09] <zeeshan|2> through your stuff :p
[22:46:10] <PetefromTn_> I kinda wish I could afford to add a big surface plate
[22:46:19] <PetefromTn_> enjoy man
[22:46:20] <zeeshan|2> why
[22:46:30] <PetefromTn_> tooling plate rather
[22:46:37] <PetefromTn_> I have a surface plate
[22:46:42] <zeeshan|2> just mic 6 it
[22:46:48] <zeeshan|2> and drill a shit load of holes
[22:46:53] <PetefromTn_> yeah I know
[22:46:54] <zeeshan|2> but i guess that size mic6 in 1/2" or 3/4
[22:46:57] <zeeshan|2> will be stupid expensive
[22:47:06] <XXCoder> PetefromTn_: expoy granite
[22:47:07] <XXCoder> ?
[22:47:08] <PetefromTn_> would need to be at LEAST 1
[22:47:13] <PetefromTn_> 1"
[22:47:19] <zeeshan|2> so about 1000 bux
[22:47:21] <zeeshan|2> or more
[22:47:26] <PetefromTn_> yeah something like that.
[22:47:33] <zeeshan|2> XXCoder: dude
[22:47:34] <PetefromTn_> Probably at least 5-600
[22:47:36] <Connor> WooT. We have movement on the Z axis again. 150IPM stalled one time.. NO OIL on the ways or the screw.. no weight either.. was on it's back.. but.. I'll fine tune it.. also, still using the original thrust bearing vs the AC bearing..
[22:47:40] <zeeshan|2> its a cicinnati arrow
[22:47:43] <zeeshan|2> a real cnc machine
[22:47:47] <zeeshan|2> not a home made router build
[22:47:51] <zeeshan|2> theres no room for a granite table on that
[22:47:57] <zeeshan|2> :-)
[22:48:07] <PetefromTn_> LOL
[22:48:08] <zeeshan|2> epoxy granite that is
[22:48:09] <Connor> Using 5i25 + 7i76 too! :)
[22:48:18] <PetefromTn_> Connor Nice man!
[22:48:38] <Connor> I think the screw might be tad bent.. but, it's hard to say.
[22:48:38] <zeeshan|2> PetefromTn_: you have a husky?
[22:48:45] <PetefromTn_> You'll be kickin' David's ass with that thing before you know it.
[22:48:54] <PetefromTn_> yeah his name is Nanuu...
[22:49:01] <zeeshan|2> cool dog
[22:49:01] <zeeshan|2> :)
[22:49:11] <Connor> PetefromTn_: Yea, I dunno about that.. that guy knows his shit.
[22:49:11] <PetefromTn_> yeah he's pretty awesome
[22:49:23] <PetefromTn_> Connor Yeah and so do you..
[22:49:32] <zeeshan|2> http://s150.photobucket.com/user/matospeter/media/IMG_20130514_224255_zps8ee81edc.jpg.html?sort=6&o=20
[22:49:35] <zeeshan|2> is that a gear shifter
[22:49:38] <zeeshan|2> for a mucie transmission?
[22:49:41] <zeeshan|2> er.
[22:49:42] <zeeshan|2> nm
[22:49:47] <zeeshan|2> thats a tool holder haha
[22:49:55] <zeeshan|2> wow i was so off
[22:50:06] <PetefromTn_> we need to design a swingarm toolchanger for your 0704 like he did LOL
[22:50:16] <PetefromTn_> yeah that is when I first made it.
[22:50:23] <zeeshan|2> http://s150.photobucket.com/user/matospeter/media/SAM_05602160x1620_zps030565b4.jpg.html?sort=6&o=8
[22:50:24] <PetefromTn_> It was the very first part I made on the Cincinatti
[22:50:29] <PetefromTn_> and I screwed it up LOL
[22:50:30] <zeeshan|2> thats the infamous calipers ssi and connor were talking about
[22:50:35] <zeeshan|2> carbide jaws
[22:50:36] <PetefromTn_> but it still works good
[22:50:42] <Connor> I LOVE his. Very compact.. it's not swing arm.. it's slide.. but.. it kicks butt.
[22:50:45] <zeeshan|2> are the ip65 coolant proof calipers the only ones with carbide jaws?
[22:50:58] <PetefromTn_> Connor Look again
[22:51:05] <PetefromTn_> he has a swingarm one
[22:51:16] <pfred1> zeeshan|2 this is a gear shift for a muncie http://i.kinja-img.com/gawker-media/image/upload/s--md8QWEMO--/18s43if4efx45jpg.jpg
[22:51:20] <PetefromTn_> I dunno but these are coolant proof and carbide
[22:51:36] <zeeshan|2> pfred ihave a t56
[22:51:41] <PetefromTn_> depends on the muncie
[22:51:42] <zeeshan|2> and holy cow theyre quite different
[22:51:47] <zeeshan|2> the only thing similar ar the syncros
[22:51:50] <zeeshan|2> *are
[22:51:59] <PetefromTn_> you have the T56 in that thing?
[22:52:05] <zeeshan|2> yes
[22:52:22] <zeeshan|2> i was rebuilding it and i learned that it was so similar to older t5 or tko or muncie trans
[22:52:24] <PetefromTn_> We are working on an adapter for them into the rotary
[22:52:32] <zeeshan|2> nice
[22:52:44] <PetefromTn_> six speed from viper right?
[22:52:46] <pfred1> I think i have a borg warner?
[22:52:53] <zeeshan|2> its six speed from a camaro
[22:52:57] <PetefromTn_> aah
[22:52:57] <zeeshan|2> pfred1: what car?
[22:53:04] <PetefromTn_> thats a kickass tranny
[22:53:07] <zeeshan|2> PetefromTn_: i have viper components in it
[22:53:08] <pfred1> a 1966 P1800S
[22:53:15] <PetefromTn_> cryo?
[22:53:23] <zeeshan|2> nahh
[22:53:36] <pfred1> I know i blew the lay shadt in it once
[22:53:46] <zeeshan|2> haha
[22:53:47] <PetefromTn_> Volvo?
[22:53:59] <zeeshan|2> your volve has a muncie?
[22:53:59] <pfred1> I asked the guy at the trans place did I miss the gear? he said, hell no, you sank it!
[22:54:24] <pfred1> no I think it is a borg warner
[22:54:35] <Connor> pete. I did look again.. it's a sider..
[22:54:35] <zeeshan|2> PetefromTn_: if you need any dimensions for the t56
[22:54:38] <zeeshan|2> definitely let me know
[22:54:43] <Connor> EXACTLY what I want to build.
[22:54:44] <PetefromTn_> I have the tranny here now
[22:55:00] <PetefromTn_> actually I have the mount plate from it.
[22:55:09] <zeeshan|2> bell housing?
[22:55:12] <PetefromTn_> already got a drawing going.
[22:55:13] <zeeshan|2> or front plate
[22:55:28] <zeeshan|2> http://i.imgur.com/yYu6bFG.jpg
[22:55:29] <zeeshan|2> which one
[22:55:29] <pfred1> my hot rodding days are over
[22:55:32] <zeeshan|2> aluminum or black one
[22:55:32] <PetefromTn_> well we are not using the viper bellhousing.
[22:55:40] <zeeshan|2> PetefromTn_: yea you cant
[22:55:46] <zeeshan|2> rotary bolt pattern is diff
[22:55:49] <pfred1> it was fun until I drove the thing
[22:55:59] <PetefromTn_> we are using auto bellhousing from RX7
[22:56:08] <zeeshan|2> ahh
[22:56:21] <pfred1> I decided i wanted to keep it under 150 MPH
[22:56:23] <zeeshan|2> so youre making an adapter plate that goes between the bellhousing
[22:56:26] <zeeshan|2> and the trans front plate
[22:56:30] <PetefromTn_> it's kinda on hold while they save their pennies for a prototype.
[22:56:42] <PetefromTn_> yeah something like that.
[22:57:05] <zeeshan|2> just one thing that is important
[22:57:22] <zeeshan|2> the input shaft on the t56 is supported on the trans side with a taper bearing
[22:57:32] <zeeshan|2> the pilot bearing on the engine is the other support
[22:57:32] <PetefromTn_> I could make one easily but they are doing so many different things over there they can't seem to concentrate on one thing LOL
[22:57:44] <zeeshan|2> so if the trans is not concentric with the crankshaft
[22:57:51] <zeeshan|2> it owns the 4th gear
[22:57:58] <zeeshan|2> and input shaft bearing
[22:58:09] <pfred1> my car can lay out 4th
[22:58:10] <zeeshan|2> PetefromTn_: if you can make that adapter plate
[22:58:12] <PetefromTn_> yeah I know. It will be concentric if I have anything to say about it :P
[22:58:14] <zeeshan|2> you dont even need to deal with them..
[22:58:22] <zeeshan|2> you can go on rx7club.com
[22:58:25] <zeeshan|2> and sell em yourself
[22:58:28] <zeeshan|2> they'll sell like hot cakes
[22:58:33] <zeeshan|2> that is a very desired product
[22:58:33] <PetefromTn_> you think so?
[22:58:36] <zeeshan|2> yes
[22:58:44] <zeeshan|2> if you can make them for a reasonable price
[22:58:45] <PetefromTn_> freakin' tranny is expensive.
[22:58:55] <zeeshan|2> well thats their job to source
[22:58:59] <PetefromTn_> did not think too many people would want them.
[22:59:00] <zeeshan|2> you provide the component to adapt :D
[22:59:16] <zeeshan|2> the rotary transmission blows up after ~380ft-lb of torque to the wheels
[22:59:20] <zeeshan|2> you need a t56 after
[22:59:23] <PetefromTn_> it's too bad you are not rotary anymore we could work together on it.
[22:59:33] <PetefromTn_> really?
[22:59:39] <zeeshan|2> and one thing about rotary (FD RX7) crowd is
[22:59:40] <zeeshan|2> they have money
[22:59:47] <PetefromTn_> They have a bunch of cars there with a lot more than that
[22:59:56] <zeeshan|2> i had one guy return a stainless steel product i made
[23:00:01] <zeeshan|2> cause i had a little bit of sugaring on the inside
[23:00:11] <zeeshan|2> he paid for return shipping to me and back
[23:00:16] <zeeshan|2> lol
[23:00:21] <PetefromTn_> I would love to get into this kind of shit. Make some real money...
[23:00:39] <PetefromTn_> I am not a tuner expert tho. I can make about anything tho.
[23:01:05] <zeeshan|2> if you lurk the forums
[23:01:07] <PetefromTn_> how did he see the sugar? Did he scope the freakin thing?
[23:01:08] <zeeshan|2> you might see what people need
[23:01:09] <PetefromTn_> LOL
[23:01:17] <PetefromTn_> got any suggestions?
[23:01:54] <zeeshan|2> hmm
[23:01:56] <PetefromTn_> I know that red car they built is sexy as hell man... Gives me a woodie LOL
[23:02:20] <PetefromTn_> Actually they just got another red car in there it was the very first one they ever built
[23:02:25] <PetefromTn_> looks very similar
[23:02:35] <PetefromTn_> that one makes around 560WHP
[23:02:38] <zeeshan|2> whats the name of the shop?
[23:02:48] <zeeshan|2> its not banzai racing is it
[23:02:52] <PetefromTn_> Addicted Performance
[23:04:00] <zeeshan|2> theyre on rx7club :D
[23:04:04] <pfred1> a guy I knew his uncle holds a worlds record in HP to volume
[23:04:08] <PetefromTn_> yeah they are everywhere
[23:04:28] <pfred1> well his uncle is dead now but as far as I know no one has ever broken the record yet
[23:04:33] <PetefromTn_> just wish they would slow down long enough for us to make some stuff...
[23:05:19] <PetefromTn_> pfred1 nice..
[23:05:30] <pfred1> he built the quad 4 olds
[23:05:39] <zeeshan|2> i was building these for the rx7s
[23:05:44] <zeeshan|2> prolly sold like 300 of em
[23:05:45] <pfred1> 220 MOH out of a 4 cylinder
[23:05:48] <zeeshan|2> http://s130.photobucket.com/user/turbozee84/media/partial_zps9b918c5c.jpg.html?sort=3&o=570
[23:06:00] <zeeshan|2> the factory oil filler neck is made out of plastic
[23:06:02] <zeeshan|2> so it cracks
[23:06:14] <zeeshan|2> and rx7s have a tendency for the oil to come out of the oil filler neck
[23:06:16] <zeeshan|2> under high g corners
[23:06:23] <zeeshan|2> so they were baffled
[23:06:31] <PetefromTn_> LOL he asked me about making something like that.
[23:06:36] <zeeshan|2> no one makes them anymore
[23:06:39] <pfred1> I have a windage tray in my car
[23:06:47] <zeeshan|2> http://s130.photobucket.com/user/turbozee84/media/production2_zps5fa7f552.jpg.html?sort=3&o=573
[23:06:52] <zeeshan|2> i was selling them for 160 bux
[23:07:10] <zeeshan|2> it was costing me about 40 bux in materials and about half an hour to weld
[23:07:20] <PetefromTn_> did you machine that base?
[23:07:25] <zeeshan|2> no
[23:07:28] <zeeshan|2> it was cheaper to get it laser cut
[23:07:31] <pfred1> it was there when I bought it
[23:07:44] <zeeshan|2> 20 of them would cost me 100 bux
[23:07:51] <PetefromTn_> nice.
[23:07:53] <zeeshan|2> i machined the o-ring groove in them
[23:08:01] <zeeshan|2> on the lathe
[23:08:10] <pfred1> RTV good enough
[23:08:10] <PetefromTn_> your CNC retro
[23:08:14] <zeeshan|2> no
[23:08:16] <zeeshan|2> manual
[23:08:16] <zeeshan|2> :D
[23:08:19] <zeeshan|2> this was a long time ago
[23:08:20] <PetefromTn_> heh
[23:08:20] <zeeshan|2> like 3 years
[23:08:32] <pfred1> I got a head that leaks unless I RTV it
[23:08:39] <pfred1> it is ported too radically
[23:08:46] <zeeshan|2> also where the filler cap screws in
[23:08:57] <zeeshan|2> the fitting i just took a regular m24 nut
[23:09:01] <pfred1> I fried some pistons with that deal
[23:09:02] <zeeshan|2> and turned it down to a cylinder lol
[23:09:07] <zeeshan|2> it was cheaper and faster to do that then thread em
[23:09:16] <zeeshan|2> *than
[23:09:31] <pfred1> metric hardware makes me want to puke
[23:09:33] <zeeshan|2> pfred1: crankshaft windage tray?
[23:09:41] <pfred1> oil pan what else?
[23:09:43] <zeeshan|2> pfred1: most cars use metric bolts :P
[23:09:53] <zeeshan|2> well you said "my car has a windage tray"
[23:09:53] <pfred1> yeah most cars make me want to puke too
[23:09:55] <zeeshan|2> most cars do ! :P
[23:09:56] <PetefromTn_> I swear I know you did not like the rotary engine but those things when they are built make a sound that makes me piss my pants hehe
[23:10:11] <pfred1> well my oil pan has ears welded to it
[23:10:16] <zeeshan|2> i dont like it because its got too much maintenance
[23:10:22] <zeeshan|2> i loved the performance and sound :)
[23:10:24] <pfred1> so when you slam into a turn the oil can slosh
[23:10:34] <pfred1> most cars don't have that
[23:10:40] <zeeshan|2> oh youre talking about baffle plates
[23:10:47] <PetefromTn_> the sound is amazing really...
[23:10:48] <zeeshan|2> that are hinged
[23:10:52] <pfred1> I call it a windage tray
[23:11:01] <PetefromTn_> I never really heard a built one until I met these guys.
[23:11:01] <zeeshan|2> thats not the right term i think
[23:11:19] <zeeshan|2> http://media.caranddriver.com/images/12q4/482258/2014-chevrolet-corvette-lt1-v-8-vvt-di-oil-pan-and-windage-tray-photo-482282-s-1280x782.jpg
[23:11:22] <zeeshan|2> thats a windage tray
[23:11:23] <PetefromTn_> love the sound..
[23:11:36] <pfred1> one really neat thing my car has is direct steel timing gears
[23:11:45] <pfred1> no belt, or chain
[23:11:56] <zeeshan|2> http://www.importmeet.com/images/project-cars/rx-7/2012/02/25/baffle_lsx-7_06.JPG
[23:11:57] <pfred1> it'll tach 10 grand all day long
[23:11:59] <zeeshan|2> this is an oil pan baffle
[23:12:14] <zeeshan|2> http://www.improvedracing.com/images/products/EGM-1000_4_lg.jpg
[23:12:19] <PetefromTn_> I am surprised at how many fabbers use stainless tube fittings on cars plumbing...
[23:12:23] <pfred1> solid lifters double over springs and moly rods too
[23:12:31] <zeeshan|2> PetefromTn_: stainless and aluminum!
[23:12:31] <zeeshan|2> win :D
[23:12:44] <PetefromTn_> yeah but those stainless fittings are heavy no?
[23:12:52] <zeeshan|2> depends on the fitting
[23:12:53] <PetefromTn_> they are really thick walled
[23:13:06] <zeeshan|2> if its a highly stressed part
[23:13:10] <zeeshan|2> stainless is worth it
[23:13:14] <PetefromTn_> http://i130.photobucket.com/albums/p252/turbozee84/parts-1.jpg
[23:13:15] <pfred1> for what?
[23:13:22] <pfred1> retaining heat
[23:13:30] <zeeshan|2> mechancial strength
[23:13:40] <zeeshan|2> PetefromTn_: youre right i coulda used aluminum
[23:13:41] <PetefromTn_> yeah I love stainless tubing but even my friend in Ohio who does race tuning uses them
[23:13:44] <zeeshan|2> but its much much cheaper to use stainless
[23:13:50] <zeeshan|2> how much do you think one of those bends cos tme?
[23:13:51] <PetefromTn_> really?
[23:13:55] <zeeshan|2> thats a 1.5" sch 10 elbow
[23:13:59] <pfred1> I built a stainless steel exhaust system because I got tored of doing exhaust work
[23:13:59] <zeeshan|2> 1" i mean
[23:14:03] <zeeshan|2> they were 2.50 each
[23:14:07] <zeeshan|2> when bought in a large quantity
[23:14:18] <pfred1> borla
[23:14:20] <PetefromTn_> maybe that is the main reason.
[23:14:25] <PetefromTn_> cost
[23:14:31] <zeeshan|2> stainless fittings are off the shelf
[23:14:33] <pfred1> yeah it cost me a few extra bucks
[23:14:35] <zeeshan|2> aluminum are usually custom made
[23:14:46] <PetefromTn_> you use vee bands?
[23:14:52] <zeeshan|2> for exhaust?
[23:14:52] <zeeshan|2> yea
[23:15:09] <PetefromTn_> what size turbo
[23:15:12] <zeeshan|2> theyre stupid expensive though
[23:15:12] * pfred1 is the exhaust system king!
[23:15:22] <zeeshan|2> pfred1: wanna compete?!!? :D
[23:15:25] <zeeshan|2> ps i hate exhaust work
[23:15:31] <pfred1> you should see the exhaust I built for this guy with a Chevelle
[23:15:33] <zeeshan|2> PetefromTn_: i have two t3/t04e 50 trims
[23:15:42] <PetefromTn_> ok
[23:15:50] <pfred1> with a crossover H pipe and cut outs
[23:16:10] <PetefromTn_> They just got some kinda big turbo for a build there yesterday.
[23:16:13] <pfred1> I insisted on the cross over pipe the cut outs were his idea
[23:16:21] <zeeshan|2> no X pipe? :p
[23:16:23] <PetefromTn_> ball bearing high quality one I cannot remember.
[23:16:29] <zeeshan|2> H pipe sounds so sexy
[23:16:33] <pfred1> a crossover pipe is an X pipe
[23:16:41] <PetefromTn_> not really
[23:16:42] <pfred1> but yeah it is an H not an X
[23:16:56] <zeeshan|2> gt42r?
[23:16:58] <pfred1> let me tell you with a V 8 they make a difference
[23:17:07] <pfred1> a big difference
[23:17:07] <zeeshan|2> pfred1: they make a huge difference
[23:17:13] <zeeshan|2> like 20 whp difference
[23:17:16] <zeeshan|2> on a 6.0L
[23:17:26] <zeeshan|2> hotrod did an article on this too
[23:17:26] <pfred1> yeah that car finally scared him and he got rid of it
[23:17:37] <zeeshan|2> same with header tube thickness
[23:17:41] <pfred1> after I rebuilt his carb and dropped an electronic ignition into it
[23:17:47] <zeeshan|2> 2" vs 1 1/4"
[23:17:48] <zeeshan|2> :p
[23:17:59] <pfred1> yeah he bought these really sweet glass headers for it
[23:18:05] <zeeshan|2> PetefromTn_: seriously i'd look into making parts for rx7
[23:18:05] <pfred1> they cost a fortune
[23:18:32] <pfred1> but we were making big money back then
[23:18:44] <zeeshan|2> http://i.imgur.com/RTwQW8g.jpg
[23:18:47] <zeeshan|2> thats my current setup
[23:18:51] <zeeshan|2> need to move the turbos up higher
[23:18:54] <PetefromTn_> http://i.imgur.com/iMZJd2s.jpg
[23:19:00] <zeeshan|2> PetefromTn_: rofl
[23:19:01] <pfred1> I never liked turbos much
[23:19:08] <pfred1> too low compression
[23:19:10] <zeeshan|2> pfred1: why not
[23:19:20] <PetefromTn_> BOOOOOOSSSSSSTTT!
[23:19:25] <pfred1> turbo lag
[23:19:27] <zeeshan|2> i can make 600 whp at 10 psi with the turbos i have
[23:19:29] <zeeshan|2> its a v8!
[23:19:32] <zeeshan|2> i make full boost at 1800 rpm
[23:19:42] <PetefromTn_> what is full boost?
[23:19:44] <zeeshan|2> turbo lag is on 4 bangers
[23:19:50] <pfred1> my car falls on its face anything under 3,600 RPM
[23:19:57] <zeeshan|2> PetefromTn_: the turbos are like a fan
[23:20:02] <pfred1> dump the clutch up there though and it goes
[23:20:02] <zeeshan|2> you blow exhaust gas on them to make em spool
[23:20:17] <zeeshan|2> you gotta blow a lot of exhaust gas on them before they can actually start compressing air
[23:20:28] <PetefromTn_> No I know what it means I am asking you what full boost pressure is on your setup duh
[23:20:40] <zeeshan|2> oh
[23:20:45] <zeeshan|2> i hit 16 ish
[23:20:49] <PetefromTn_> ah
[23:20:49] <zeeshan|2> on the race track
[23:20:54] <zeeshan|2> street is 10ish
[23:21:12] <zeeshan|2> pfred1: what engine?
[23:21:21] <pfred1> a 1969 B-20B
[23:21:29] <pfred1> bored 122 over
[23:21:31] <PetefromTn_> I keep hinting them I want to take a ride in the 700+hp monster RX7 they built.
[23:21:56] <zeeshan|2> 2.0L
[23:22:09] <zeeshan|2> whats 122 over
[23:22:10] <pfred1> I donno how much HP my car makes I know it is fast though
[23:22:19] <pfred1> 0.122 of an inch in diameter
[23:22:36] <pfred1> you know when peole say 40 over?
[23:22:39] <zeeshan|2> yea
[23:22:43] <zeeshan|2> thats why i asked
[23:22:45] <pfred1> yeah my engine is 122 over
[23:22:48] <zeeshan|2> thats not a common bore over size
[23:22:48] <zeeshan|2> haha
[23:23:07] <pfred1> thick casting oin the 69 blocks
[23:23:08] <zeeshan|2> dude that thing is a tank
[23:23:10] <zeeshan|2> its got a cast iron head
[23:23:11] <zeeshan|2> haha
[23:23:29] <zeeshan|2> the nice thing about cast iron heads is, they are impossible to warp
[23:23:33] <zeeshan|2> when you overheat the car
[23:23:36] <zeeshan|2> *head
[23:23:38] <pfred1> I donno aboutthat
[23:23:45] <zeeshan|2> you warped yours?
[23:23:50] <pfred1> my head is shaved down so much I worry about it
[23:24:11] <PetefromTn_> I would make parts for that car but I don't have one and not sure what they really need. Would be fun tho.
[23:24:35] <PetefromTn_> I need to try to buy one cheap and build it up hehe
[23:24:43] <PetefromTn_> excuse to buy a nice toy.
[23:25:03] <pfred1> meh for a few years I was into hot rodding
[23:25:19] <pfred1> then when I got it on the road I was like this is stupid
[23:25:39] <pfred1> so now it rots in the backyard
[23:28:26] <pfred1> http://i.imgur.com/Hh6FS3j.jpg
[23:28:36] <pfred1> those are real mags
[23:28:45] <pfred1> made out of real magnesium
[23:28:51] <pfred1> they're illegal
[23:32:20] <zeeshan|2> why
[23:32:35] <zeeshan|2> looks like a nice car
[23:32:37] <zeeshan|2> :]
[23:32:39] <zeeshan|2> drive it
[23:34:13] <XXCoder> if it ever gets on fire...
[23:34:16] <XXCoder> major fire
[23:44:21] <XXCoder> zeeshan|2: ever set magnesium on fire?
[23:44:53] <zeeshan|2> ?
[23:44:55] <zeeshan|2> yea
[23:45:01] <zeeshan|2> i work with magnesium in the metal forming lab
[23:45:03] <zeeshan|2> its not illegal
[23:45:15] <zeeshan|2> it already exists in door skins of a car
[23:45:18] <XXCoder> drat always wanted to burn one for fun
[23:45:23] <XXCoder> safely of course
[23:45:49] <zeeshan|2> the alloys im working with arent that spontaneous
[23:45:51] <XXCoder> dunno if law is illegal anywhere in usa but yeah it burns. I never said it was illegal though, pf did
[23:45:54] <zeeshan|2> real mg is supposed to react with water
[23:45:56] <zeeshan|2> this stuff barely does
[23:46:23] <zeeshan|2> o
[23:46:24] <zeeshan|2> ;)
[23:46:28] <zeeshan|2> i thought you were implyingh!
[23:51:22] <pfred1> zeeshan|2 mags tend to explode
[23:51:35] <pfred1> which is why they don't make rims out of it anymore
[23:51:52] <pfred1> magnisum will shatter
[23:51:55] <zeeshan|2> what?
[23:52:02] <zeeshan|2> porsche carrera gt uses mag wheels
[23:52:12] <XXCoder> maybe different alloy?
[23:52:17] <pfred1> mag rims were banned in the 70s
[23:52:25] <XXCoder> pfred1: usa?
[23:52:25] <zeeshan|2> maybe pure mag wheels
[23:52:58] <pfred1> they're so light though
[23:53:04] <pfred1> way lighter than aluminum
[23:53:22] <XXCoder> I can't wait for day when titanium becomes cheap
[23:53:33] <XXCoder> its amazing but hard to make still :(
[23:54:13] <zeeshan|2> 0.098lb/in^3 Mg vs .063lb/in^3 Al
[23:54:27] <zeeshan|2> whoops
[23:54:29] <zeeshan|2> backwards
[23:54:40] <zeeshan|2> not that huge of a difference :P
[23:54:55] <pfred1> all I know is I've never lifted tires lighter than mine and i used to work at a tire place so I've lifted more than my fair share
[23:55:46] <pfred1> including those obnoxious no profile tires
[23:55:58] <XXCoder> alum is 1.5 times approx heavier
[23:56:03] <pfred1> we had french overarm machines for those
[23:56:03] <XXCoder> that makes heck of difference
[23:56:11] <XXCoder> assuming equal volume
[23:56:14] <zeeshan|2> 10 lb vs 15lb
[23:56:15] <zeeshan|2> big deal
[23:56:18] <zeeshan|2> its not like
[23:56:26] <zeeshan|2> steel vs al!
[23:56:28] <pfred1> it is a big deal when it is a dynamic part
[23:56:30] <XXCoder> higher rolling resistance
[23:56:41] <pfred1> spinning, and going up, and down
[23:56:41] <zeeshan|2> i much rather have something that doesnt explode
[23:56:47] <zeeshan|2> on a critical location
[23:56:48] <zeeshan|2> :)
[23:57:00] <pfred1> yeah until they exp;lode they're really nice
[23:57:22] <zeeshan|2> what worries me is we develop so much stuff for GM
[23:57:30] <zeeshan|2> metalforming techniques for magnesium
[23:57:32] <zeeshan|2> so it's making a huge comeback
[23:57:39] <zeeshan|2> so car fires in the future will be scary
[23:57:42] <pfred1> I donno how common them breaking is probably was some isolated incidents and the regulators overreacted
[23:57:44] <zeeshan|2> 2025~
[23:57:50] <pfred1> mine have never exploded on me
[23:58:39] <XXCoder> mg is making a comeback in leasy till we ever figure how to cheaply make titanium like we did with alum
[23:58:49] <XXCoder> did you know alum used to be more expensive than gold?
[23:58:54] <pfred1> I used to go to a motorcycle race and camp out and the crowd was pretty rowdy they'd burn VW engines on fires
[23:58:58] <XXCoder> thats why usa spire has alum cap
[23:59:01] <pfred1> VW engines are magnisum
[23:59:19] <pfred1> it looked ilke ET was landing
[23:59:48] <pfred1> they'd throw pots of water on the blocks while they were burning so they'd explode
