[00:00:03] <zeeshan> duhh
[00:00:03] <zeeshan> film.
[00:00:19] <zeeshan> anything with polymer shuts my brain down
[00:00:42] <CaptHindsight> SLA/DLP 3d printers, UV cured inks and coatings
[00:01:01] <CaptHindsight> printed electronics
[00:01:22] <CaptHindsight> we can print PCB's with just fluids
[00:01:34] <CaptHindsight> the board, conductors, everything
[00:01:45] <zeeshan> wow
[00:01:46] <cathode> crazy
[00:01:52] <cathode> what about the traces?
[00:02:03] <cathode> some sort of copper solution?
[00:02:10] <CaptHindsight> yes, the traces using copper or silver
[00:03:09] <CaptHindsight> there are several approaches, one might be copper nanoparticles coated with a polymer to keep them from oxidizing
[00:03:40] <CaptHindsight> you print the particles then blast them with UV to flash off the polymer and sinter at the same time
[00:04:51] <CaptHindsight> silver is easy, you just print with a silver nanoparticle ink, you can make the silver ink pretty easily
[00:05:20] <CaptHindsight> but silver is expensive
[00:08:37] <WalterN> just make some silver
[00:08:43] <WalterN> no big deal these days, right?
[00:08:50] <WalterN> XD
[00:13:14] <CaptHindsight> http://vimeo.com/93968312 not mine but a slow low res way to do it
[00:13:23] <CaptHindsight> zeeshan: ^^
[00:16:07] <zeeshan> haha
[00:16:11] <zeeshan> that is so cool
[00:16:26] <zeeshan> hopefully a mutant chicken doesnt come out of that egg
[00:17:03] <CaptHindsight> http://www.youtube.com/watch?v=EBlqPS8boLI Make Conductive Silver Ink (complex ion based)
[00:22:35] <CaptHindsight> copper is $3.0785/lb. silver is $258/lb yet the commercial inks sell for hundred or thousands per ounce
[00:25:54] <WalterN> the half hard copper I get is $6/lb
[00:26:51] <CaptHindsight> http://www.nasdaq.com/markets/copper.aspx
[00:29:59] <CaptHindsight> WalterN: do you buy large quantities of it?
[00:30:13] <WalterN> I don't, my customer does
[00:30:50] <WalterN> rather large... possibly the shop that uses the most 1.5" diameter copper rod
[00:31:02] <WalterN> in the northwest USA
[00:31:36] <CaptHindsight> Aluminum is ~$0.90/lb but shapes, sheet and plate always costs a few times more
[00:32:06] <zeeshan> send me free copper!
[00:32:06] <WalterN> sometimes we go though 50 12' bars of copper in a week or so
[00:32:08] <zeeshan> :-
[00:32:12] <zeeshan> i need some heat sinks for weldin
[00:34:08] <WalterN> probably will go though more per week as time moves on
[00:37:04] <WalterN> aluminum scrap right now is something like $0.35/lb
[00:37:23] <WalterN> copper scrap is about $2.3/lb
[00:57:17] <CaptHindsight> my last load of aluminum swarf was like 20 cents per lb
[00:57:33] <XXCoder> you buy swarf and melt em or what
[00:57:43] <XXCoder> or it was sell to someone?
[00:57:52] <CaptHindsight> but i didn't shop around for best buyer
[00:58:08] <CaptHindsight> selling my chips
[00:58:17] <XXCoder> why not melt em down so you has decent slabs
[00:58:24] <XXCoder> kiln isnt that expensive
[00:59:03] <CaptHindsight> yeah, makes sense with how little they offer
[00:59:33] <XXCoder> yeah
[01:03:20] <WalterN> it would be nice to be able to take the shavings and reform it into bars of material so I can use it again... heh
[01:03:39] <XXCoder> you can
[01:03:50] <XXCoder> just try to expose as little air as you can
[01:04:20] <XXCoder> and from what I learned from videos, you need something to purge alum of air.
[01:04:43] <WalterN> I don't really care about aluminum... talking about copper
[01:04:45] <XXCoder> flux I think
[01:04:52] <XXCoder> oh copper I has no idea
[01:05:12] <CaptHindsight> http://www.youtube.com/watch?v=M5gchI6dv-o Briquetting of Aluminium
[01:06:13] <XXCoder> wow that video resolution sucks
[01:07:19] <CaptHindsight> http://www.youtube.com/watch?v=MWVXe_J7onA works for copper
[01:07:45] <zeeshan> why arent chips worth a lot
[01:07:54] <CaptHindsight> heh, only one guy wears a mask
[01:08:06] <XXCoder> lots energy to make slabs from em I guess?
[01:08:26] <zeeshan> versus aluminum wheels and other scrap?
[01:08:32] <zeeshan> id think itd be less
[01:08:35] <XXCoder> really no idea
[01:08:43] <zeeshan> more surface area exposure
[01:08:52] <WalterN> copper has a lot higher melting point, and it conducts heat better
[01:09:11] <XXCoder> capt thats interesting blurry videp
[01:09:20] <zeeshan> http://www.posner.ca/pricelist/autolist_online.pdf
[01:09:37] <zeeshan> .40 for aluminum turnings
[01:09:50] <zeeshan> vs 72 cents for painted al
[01:10:00] <zeeshan> i dont get it :P
[01:10:07] <XXCoder> me either
[01:10:37] <CaptHindsight> it has coolant mixed in but I think it just tradition
[01:10:45] <XXCoder> CaptHindsight: I guess those compacted alum is easier to melt too
[01:10:57] <XXCoder> less air to remove
[01:11:47] <XXCoder> anyway night
[01:12:49] <CaptHindsight> http://www.ars-inc.com/faq-home.aspx#q1 Q: Why are briquettes more valuable than scrap metal chips?
[01:13:10] <Connor> Hmm.. 6 gallon air compressor.. 45 dB(A) $475.00
[01:14:15] <CaptHindsight> thats pretty quiet
[01:14:33] <Connor> http://www.jun-air.com/product_detail.aspx?ProductID=633&ProductTypeID=50
[01:14:43] <Connor> http://knoxville.craigslist.org/tls/4714166132.html
[01:15:28] <CaptHindsight> http://www.industrialnoisecontrol.com/comparative-noise-examples.htm
[01:15:47] <zeeshan> ahh slagg
[01:16:20] <Connor> I HATE my air compressor..
[01:16:51] <Connor> I hate loud noises.. in fact.. I enclosed my shop vac in a 3/4" MDF box and vent it under the house. via 4" Hoses.
[01:17:54] <Connor> Wonder if it would have enough CFM for my draw bar.
[01:19:48] <zeeshan> why is cfm important for an air solenoid
[01:20:09] <Connor> Umm.. It's not. It's the air cylinder.
[01:20:15] <zeeshan> i mean air cylinder
[01:20:23] <zeeshan> i dont know why i said solenoid
[01:20:25] <Connor> Time it takes to operate it.
[01:20:26] <zeeshan> 2:00 am thats why
[01:20:46] <zeeshan> hm?
[01:21:10] <Connor> The amount of time it would take to fill up the air cylinder..
[01:21:57] <Connor> Kinda mute point.. Don't have the $$$ to get it.
[01:22:19] <zeeshan> well the way i think of it is if your cylinder is 1L
[01:22:31] <zeeshan> lets make it simpler
[01:22:32] <zeeshan> 1 feet
[01:22:37] <zeeshan> and your tank provides 5 scfm
[01:22:47] <zeeshan> i'd take 1/5 of a minute to fill it?
[01:23:43] <Connor> My air Cylinder is a 3" Bore, 1" Stroke, triple stack
[01:24:33] <zeeshan> 7.0 cubic inches
[01:24:36] <zeeshan> so 0.004 cubic feet
[01:24:45] <Connor> TRIPPLE STACK
[01:24:48] <zeeshan> times 3
[01:25:04] <Connor> at @100 PSI, it would take 3 seconds
[01:25:12] <zeeshan> big deal
[01:25:12] <zeeshan> lol
[01:25:17] <Connor> and require 1.91 CFM
[01:25:55] <Connor> Not sure what FAD is.. but at max pressure.. 1.31cfm,
[01:26:08] <Connor> FAD @ Max Pressure (60 Hz)1.31 cfm (37 l/min)
[01:26:14] <Connor> Displacement (60 Hz)2.12 cfm (60 l/min)
[01:26:41] <zeeshan> fad ive heard that before
[01:26:50] <zeeshan> free air delivery
[01:27:26] <Connor> You should see it work from my scuba tank setup.
[01:27:42] <Connor> Oh. not sure this makes a diff... but the stroke it moves isn't a full 1"
[01:27:49] <zeeshan> that will make a huge diff
[01:27:53] <zeeshan> less volume
[01:27:58] <Connor> probably more like 1/4 to 1/2
[01:28:10] <zeeshan> so bascially 1/4 or 1/2 of 3 seconds :P
[01:28:28] <Connor> http://www.leinarts.com/aircalc.htm
[01:29:09] <zeeshan> you dnt need a calculator :P
[01:29:29] <zeeshan> volume = 0.25*pi*d^2 * length
[01:29:31] <Connor> zeeshan: Don't start.
[01:29:43] <zeeshan> divide scfm of your compressor w/ that volume.
[01:29:57] <Jymmm> or a chop saw!
[01:30:17] <zeeshan> its just volume of a cylinder / your air flow @ compressor
[01:30:33] <zeeshan> Jymmm: ill chopsaw you!
[01:30:51] <Connor> I wonder what the CFM of a scuba tank is...
[01:30:52] <Jymmm> zeeshan: go play with your calculator!
[01:31:02] <zeeshan> well formulas are important
[01:31:10] <zeeshan> because you can clearly see length is linearly related w/ time
[01:31:19] <zeeshan> so if you halfed your length, you'd half the time
[01:31:28] <zeeshan> but if you halfed the diameter, you'd 1/4 your time
[01:32:37] <zeeshan> im still confused on how to pick a hydraulic power pack for my press
[01:33:22] <zeeshan> the cylinder has a 7.25" stroke, unknown bore
[01:34:43] <zeeshan> i was thinking you just select the psi you need to generate, but connor made me realize time is important too
[01:35:05] <Connor> Your press ?
[01:35:14] <zeeshan> yea the 20 ton hydraulic press
[01:35:17] <zeeshan> it has a manual pump
[01:35:19] <zeeshan> really annoying to use
[01:35:27] <Connor> oh.
[01:35:34] <zeeshan> i was hoping i could somehow put a 1hp motor power pack on it and make it work
[01:35:47] <zeeshan> but im not sure what psi it needs to generate
[01:35:50] <zeeshan> and how it'll be controlled
[01:36:06] <zeeshan> like i dont want to always put 20 tons of pressure on something
[01:36:15] <zeeshan> sometimes i want to be genetle, so how do you control that
[01:36:43] <Connor> no clue. Beyond my knowledge.
[01:38:31] <Connor> http://www.ivdc.com/cnc/mill_10_31_14_01.jpg
[01:38:37] <Connor> I'm liking the looks of this now..
[01:38:49] <Jymmm> zeeshan: hormones
[01:38:59] <zeeshan> Jymmm: haha
[01:39:34] <zeeshan> connor use zip tie mounts to hold that black power wire!
[01:39:35] <zeeshan> :p
[01:40:02] <Connor> Eh? Which wire ?
[01:40:09] <zeeshan> the black one
[01:40:14] <zeeshan> it goes from your speed control board i think
[01:40:29] <zeeshan> to the bak slots of the case
[01:40:37] <zeeshan> where pci boards usually stick out from
[01:40:49] <Connor> Yea.. I was zip tied..
[01:41:00] <Connor> still working on it.
[01:41:08] <Connor> have more wires to run and stuff.
[01:41:13] <zeeshan> ah
[01:41:29] <Connor> way more wires to go into the 7i76
[01:41:45] <Connor> need to trim up the wires on the DB9.
[01:42:15] <zeeshan> hey do you know if theres anyway to get more than 6 analog outputs
[01:42:17] <Connor> need to wire in the 12v side of the coolant pump to a jack.
[01:42:22] <zeeshan> than what comes with 7i77
[01:42:47] <Connor> No idea. that's a question for pcw_home
[01:42:54] <Connor> why do you need them ?
[01:43:11] <zeeshan> i was really thinking about putting a 6 axis robot on the lathe
[01:43:23] <zeeshan> and making it do tool changes and load up things in the center
[01:43:26] <zeeshan> and chuck
[01:43:34] <zeeshan> it'd be a cool project :P
[01:43:50] <Connor> what sort of 6-axis robot? DIY or a existing one ?
[01:43:57] <zeeshan> probably an existing one
[01:44:41] <zeeshan> and then i can turn it 180 degree around
[01:44:48] <zeeshan> and make him hold a welding torch to weld stuff for me!
[01:48:45] <Connor> http://www.ebay.com/itm/SCORBOT-ER-III-ROBOT-MECHANICAL-ARM-SER-4070063-NO-CONTROLLER-/361094243342?pt=Educational_Toys_US&hash=item5412e4e40e
[01:48:54] <Connor> I played with one of those when I was in High school
[01:51:18] <zeeshan> how much weight can they handle
[01:51:36] <Connor> I don't really know.. We moved around little wooden balls.
[01:52:27] <Connor> 2.2LB
[01:52:39] <Connor> 1. Do not overload the arm. The workload may not exceed 1 kilo (2.2 lb.). The gripper
[01:52:39] <Connor> should grasp a workload at its center of gravity.
[01:52:44] <Connor> http://www.theoldrobots.com/book45/ER3-Manual.pdf
[01:52:58] <zeeshan> doh
[01:54:32] <Connor> It's probably out of a high school robotics lab.
[01:55:33] <Connor> I almost purchased one with controller for $250.00 + shipping..
[01:56:27] <ReadError> we had one of those is middle school ;)
[01:56:37] <ReadError> had to program it to move a ball and stack blocks
[01:56:48] <Connor> ReadError: Exactly what I did.
[01:57:06] <Connor> move them from a queue to cups.. then.. pick them back up and place them back on the queue rack
[03:18:07] <Deejay> moin
[03:26:26] <WalterN> 1 hour into morning
[04:32:33] <archivist> last steaming of the year today and tomorrow http://www.middleton-leawood.org.uk/leawood/
[07:43:54] <jthornton> have fun archivist
[07:45:36] <Tom_itx> morning
[07:45:55] <Tom_itx> better stoke the fire this morning!
[07:46:45] <Tom_itx> 30F
[07:47:51] <Jymmm> /me hands Tom_itx two gallons of gasoline
[07:48:28] <Jymmm> ...and a road flare
[07:48:54] <Jymmm> Tom_itx: you're on your own after that!
[07:49:50] <jthornton> 30F here too
[07:50:27] <Jymmm> cold here too... 51F
[07:50:27] <jthornton> hmmm linux don't know how to make the degree symbol so Tom_itx must be on a windoze computer
[07:50:44] <Jymmm> 96%
[07:50:56] <Jymmm> jthornton: copy and pasted it probably
[07:51:10] <Tom_itx> shhh
[07:53:27] <jthornton> dang I slept in this morning
[07:55:11] <Tom_itx> happens to the best
[07:55:35] <Tom_itx> they just don't say so
[08:26:47] <jthornton> I can't even blame it on DST
[08:28:08] <Tom_itx> no not yet!
[08:41:12] <jthornton> I can blame it on Remy Martin I assume
[08:42:24] <Tom_itx> that could pass as legit
[10:07:46] <ssi> morn
[10:26:12] <Loetmichel> mornin'
[10:26:18] <ssi> morn
[10:26:22] <PetefromTn_> morning
[10:26:34] <ssi> how's the cleanup going pete?
[10:26:44] <PetefromTn_> scrubbin'!
[10:26:47] <ssi> :)
[10:27:01] <PetefromTn_> it is actually a nice clean lathe under all that crud hehe
[10:27:29] <PetefromTn_> been trying to find some cash to buy some motors and drives etc
[10:28:41] <ssi> you figure out what you need?
[10:29:04] <PetefromTn_> well yeah sorta, The machine has 1-1 heavy timing belt drives on X and Z
[10:29:23] <PetefromTn_> so I can basically put any nema 34 motor I want on there or smaller frame if I want
[10:29:43] <ssi> what's the X motor?
[10:30:03] <PetefromTn_> its apparently an AC servo with resolver 750 watt
[10:30:20] <PetefromTn_> but as you know I have no Z motor
[10:30:23] <ssi> yeah
[10:30:29] <ssi> I'd try to get a 1kw servo or so for Z
[10:30:40] <PetefromTn_> so I was thinking about selling it and getting matched servos and drives
[10:30:52] <ssi> ahh
[10:30:54] <PetefromTn_> I don't think that is necessary really
[10:31:06] <PetefromTn_> 750 watt should be more than enough
[10:31:23] <PetefromTn_> if it is not I can always change the pulley sizes
[10:31:58] <PetefromTn_> I would love to get some cheap drives like you have been getting on ebay for it
[10:32:10] <PetefromTn_> what are they called again?
[10:33:18] <PetefromTn_> by cheap I mean low cost obviously
[10:37:49] <ssi> AMC
[10:37:54] <ssi> they make a ton of different kinds
[10:38:11] <ssi> you can use the brushless drives for brush motors, but you can't use the brush drives for brushless motors
[10:38:39] <ssi> personally unless that X motor is worth a bunch of money, I'd probably keep it, and just try to get a Z motor inexpensively
[10:38:44] <ssi> and a couple appropriate AMC drives
[10:38:58] <Loetmichel> ssi: you CAN use the brush drivers for brushless
[10:39:02] <PetefromTn_> I need to find a matched pair of motors suitable on the bay I guess and then get appropriate drives
[10:39:11] <Loetmichel> 2 of them and a new firmware ;-)
[10:39:20] <ssi> Loetmichel: lol
[10:39:32] <PetefromTn_> well I honestly don't even know if it works or not.
[10:39:48] <PetefromTn_> and since I have no drive for it I have no way to check it out.
[10:40:53] <PetefromTn_> and you know me I don't like screwing with it I would just rather buy new motors and drives if I can. Gotta see how much cash I can scrape up.
[10:42:59] <ssi> well in that case you should save up and get some kits like you did on the vmc
[10:51:11] <PetefromTn_> Hows the house and whatnot coming?
[10:55:35] <ReadError> snow ;(
[10:55:38] <ReadError> its so early
[10:58:14] <PetefromTn_> yeah we got some snow last night too
[11:08:02] <_methods> it's global warming
[11:08:14] <XXCoder> yeah. its making cold votex like lasy year
[11:08:23] <_methods> it got so warm in the arctic the cold moved down here
[11:08:24] <XXCoder> its going to be fucking cold this year again
[11:09:07] <_methods> silliness
[11:10:54] <_methods> i'm about to go release some methane and freon
[11:11:02] <_methods> not really diggin this cold
[11:11:18] <XXCoder> just wait few more years
[11:11:36] <XXCoder> then greenland will run out of ice and oceans warm up faster
[11:11:52] <XXCoder> then... all heat you want! or not want.
[11:12:45] <SpeedEvil> http://www.ebay.co.uk/itm/Reject-Insulation-2400x1200-Various-Sizes-Kingspan-Insulation-Board-Seconds-/141389391991?pt=LH_DefaultDomain_3&var=&hash=item20eb76e877 Just get that
[11:13:19] <XXCoder> or move to venus
[11:13:27] <XXCoder> heard its hottest planet in solar system
[11:13:42] <_methods> sign me up
[11:13:53] <_methods> just don't put me on one of dem exploding rockets
[11:14:14] <XXCoder> recent one exploded because operator hit "explode rocket" button
[11:14:22] <_methods> the other one too
[11:14:28] <XXCoder> its way to save surrounding areas when rocket screws up
[11:14:31] <_methods> virgin 2 lol
[11:14:53] <XXCoder> yeah too bad on that :( we DESPERATELY need more ways to space.
[11:14:56] <_methods> i think it's a stunt to spin up anti russian rocket engine sentiment lol
[11:15:05] <SpeedEvil> The Antares was using _50_ year old russian engines.
[11:15:18] <SpeedEvil> Not the design of - actual ones sitting in a warehouse
[11:15:26] <_methods> i think i still use some 50 y/o mills at work
[11:15:30] <XXCoder> oh talking about space... my nephew managed to land bigass lander with big rover on mun in KSP :)
[11:15:36] <SpeedEvil> _methods: yeah - sure.
[11:15:38] <XXCoder> im so proud, he beat me
[11:15:50] <_methods> hehe
[11:15:55] <XXCoder> he needed help on landing from me but otherwise..
[11:16:02] <SpeedEvil> _methods: But - it's unliekly that forexample all the paperwork on the engine construction is preserved too
[11:16:55] <XXCoder> we need fusion or antimatter in order to throw away toy chemical rockets and finally have real rockets
[11:16:57] <_methods> heheh you don't need paper to launch a rocket
[11:17:11] <_methods> or blow one up
[11:17:11] <XXCoder> you do actually. lots of paper. as in paperwork
[11:17:42] <SpeedEvil> _methods: you need the paper to find that engine #48 is the one Sergei droppd the spanner in and thought he got it out, but had had rather a lot of vodka by then.
[11:17:54] <_methods> heheh
[11:17:58] <_methods> did they document that
[11:18:18] <_methods> sergei drunk again in main engine wearing monkey suit
[11:18:21] <SpeedEvil> Probably not in those terms- but concerns about specific issues with engines will be documented
[11:18:34] <SpeedEvil> Ideally - at least
[11:18:38] <_methods> doing strange things with bananna
[11:19:12] <SpeedEvil> Or records of repairs done by techniques now realised to lead to stress concentrations, or ...
[11:19:20] <_methods> ugh i got my ballscrews for my x2 i should be drawing shit
[11:19:27] <_methods> but i'm drunk already
[11:19:40] <_methods> drinking and drawing is bad
[11:55:49] <zeeshan> PetefromTn_: are your motors DC brush?
[11:55:52] <zeeshan> or brushless
[11:58:36] <zeeshan> grrrr
[11:58:45] <PetefromTn_> Well at first I was under the impression they were DC brushless but after speaking to their engineer and PCW and looking over the information I received on them it appears they are brushless AC servos
[11:58:50] <zeeshan> i just checked my tracking now and it says attempted delivery for the drives
[11:58:55] <zeeshan> i totally missed them on friday :(
[11:59:02] <zeeshan> now i gotta wait till tuesday to get em
[11:59:20] <zeeshan> PetefromTn_: ooo nice
[11:59:26] <PetefromTn_> or rather IT is a brushless AC servo
[11:59:48] <zeeshan> i always get confuysed
[11:59:55] <PetefromTn_> yeah it would be nice if I had both of the motors here
[12:00:00] <zeeshan> theres brushless AC servos
[12:00:07] <zeeshan> and then brushless DC servos
[12:00:09] <PetefromTn_> but as it is I only have the X motor and no drives at all
[12:00:16] <zeeshan> or are they the same thing
[12:00:40] <zeeshan> or are all DC servos brushed
[12:00:49] <PetefromTn_> I have no idea
[12:01:03] <PetefromTn_> the engineer told me that they were just brushless servos.
[12:01:06] <zeeshan> you can probably get good money off ebay
[12:01:16] <PetefromTn_> PCW said they are AC brushless servos
[12:01:18] <zeeshan> does it have any controls on it?
[12:01:22] <PetefromTn_> no
[12:01:36] <PetefromTn_> which is why I got it so cheap
[12:01:55] <PetefromTn_> I would have gutted it anyways but if it had control I would have tried to sell it all
[12:02:15] <zeeshan> so you're pretty much starting from scratch
[12:02:36] <PetefromTn_> yeah like I said that is how I want it. I did the same thing with the Cincinatti
[12:03:03] <PetefromTn_> it costs a bit more in the long run but all the stuff will be brand new and replaceable if it should fail for reasonable prices
[12:03:17] <zeeshan> thats what pushed me to rip all my controls out and sell em
[12:03:24] <zeeshan> i only kept the glass scales and dc servo motors
[12:03:29] <PetefromTn_> IMNSHO it is the best way
[12:03:37] <zeeshan> cause lets say i blow up a dc servo motor, i can replace it with any other dc servo motor
[12:03:39] <zeeshan> retune it
[12:03:41] <zeeshan> and its good to go
[12:03:57] <PetefromTn_> this machine is belt driven with timing belts 1-1 on both axes
[12:04:09] <PetefromTn_> I can actually run ANY motor with sufficient power on it
[12:04:23] <PetefromTn_> hell I could even run a bigass stepper if I wanted to like you did.
[12:04:53] <zeeshan> does it have any scales on it
[12:04:59] <PetefromTn_> no
[12:06:19] <zeeshan> i have a 2.9hp motor for Z and 1.5 for X and Y and its a 3:1 drive ratio
[12:06:26] <zeeshan> seems a bit excessive
[12:06:40] <PetefromTn_> for what machine?
[12:06:45] <zeeshan> the mill
[12:07:16] <PetefromTn_> AC servos?
[12:07:22] <zeeshan> DC brush motor
[12:07:44] <zeeshan> what do you think you want your lathe to rapid at?
[12:07:46] <PetefromTn_> yeah that seems quite excessive unless the table is massively heavy or the knee or whatever
[12:07:55] <zeeshan> its meant to move 500kg loads
[12:07:58] <zeeshan> apparently
[12:08:08] <zeeshan> er
[12:08:09] <zeeshan> 300kg
[12:08:12] <zeeshan> so about 600lb
[12:08:17] <PetefromTn_> I would probably be happy with a 400 IPM rapid on the lathe I think.
[12:08:26] <zeeshan> then don't do what i did!
[12:08:30] <zeeshan> i'm no where close to that :(
[12:08:44] <zeeshan> i get maximum 180~ rapid without step loss on Z
[12:08:46] <PetefromTn_> it is not really that necessary on a CNC lathe I think
[12:08:53] <zeeshan> and 100 ipm on X
[12:09:04] <PetefromTn_> most of the work is right up against the chuck
[12:09:04] <zeeshan> with the 1200oz-in steppers
[12:09:29] <zeeshan> yea i honestly dont think i'd benefit much by making it go faster
[12:09:43] <PetefromTn_> even when I get the toolchanger the most it will move is about eight to ten inches away and change tools and run back to the work
[12:09:50] <zeeshan> with the current steup i can do a .25" doc in aluminum
[12:10:00] <PetefromTn_> yes we know
[12:10:02] <zeeshan> at .375" doc the motor spit stalls
[12:10:07] <zeeshan> *spindle
[12:10:17] <zeeshan> so i think i coulda gone with smaller steppers like 800oz-in
[12:10:18] <PetefromTn_> the point of a CNC lathe is not really massive DOC
[12:10:31] <zeeshan> and allowed it to rapid more faster
[12:10:44] <zeeshan> why not?
[12:10:55] <PetefromTn_> just fast and proper doc with reasonable feeds
[12:11:10] <zeeshan> if youre using a vnmg 433 insert
[12:11:17] <zeeshan> the minimum doc is like .2"
[12:11:51] <PetefromTn_> yeah if you have the power and speed and rigidity to do it right.
[12:11:51] <CaptHindsight> http://www.shars.com/products/gallery/20207/202-2002-3E.jpg/ http://www.shars.com/products/gallery/20207/202-2002-3J.jpg/
[12:12:00] <zeeshan> which i do
[12:12:01] <CaptHindsight> PetefromTn_: http://www.shars.com/products/view/418/6quot_Standard_HorizontalVertical_Indexing_Spacer_and_Rotary_Index
[12:12:02] <zeeshan> cause it leaves a ncie finish
[12:12:24] <zeeshan> i was doing that .25" doc cut to get an idea how deep i can go in steel
[12:12:31] <zeeshan> and i think the answer is .100"
[12:12:40] <CaptHindsight> http://www.shars.com/products/view/418/6quot_Standard_HorizontalVertical_Indexing_Spacer_and_Rotary_Index Maximum individual division spacing error: 25 seconds
[12:12:49] <zeeshan> which is really needed for the vnmg331 and 332 inserts im running
[12:12:51] <PetefromTn_> CaptHindsight I used to have a Yuasa Super Accra Dex indexing spacer like that
[12:13:11] <PetefromTn_> it was an eight inch chuck
[12:13:27] <CaptHindsight> this looks pretty easy to motorize and automate
[12:13:42] <zeeshan> i'll motorize you CaptHindsight
[12:13:43] <PetefromTn_> yeah probably
[12:13:59] <PetefromTn_> they are certainly heavy duty little monsters
[12:14:07] <PetefromTn_> the Yuasa I had was real nice
[12:14:11] <PetefromTn_> I should have never sold it
[12:14:26] <PetefromTn_> I thought I did not need it anymore when I got the CNC and needed the money for other things.
[12:14:34] <PetefromTn_> Now I kick myself in the ass for letting it go.
[12:14:41] <zeeshan> rotary tables are so expensive
[12:14:47] <zeeshan> i scour for them on kijiji
[12:14:52] <zeeshan> theyre all in the 300-800 range
[12:14:58] <PetefromTn_> I got the one I had for like $200.00 used
[12:15:01] <zeeshan> and theyre HUGE!
[12:15:14] <zeeshan> i dont know where people use these 20" rotary tables
[12:15:25] <CaptHindsight> 25 arcseconds =0.00694444444 degrees,
[12:15:41] <zeeshan> CaptHindsight: what about backlash in that style of rotary tables
[12:15:46] <PetefromTn_> My shop is full of crap right now I got that new Air conditioning unit in there which makes it even worse
[12:16:07] <zeeshan> clean her up!
[12:16:13] <PetefromTn_> I cannot even try to install the AC unit now since it is snowing outisde
[12:16:21] <zeeshan> its snowing?
[12:16:26] <PetefromTn_> I need to pour the slab for the new unit and cannot do that in the freezing cold
[12:16:29] <PetefromTn_> yeah
[12:16:33] <zeeshan> wow
[12:16:38] <zeeshan> it's not even snowing up here
[12:16:46] <CaptHindsight> snow missed us
[12:16:56] <Tom_itx> the cold didn't
[12:16:57] <zeeshan> i thought tn was a warmer climate?
[12:16:57] <PetefromTn_> we got a couple inches last night but it is mostly melted now
[12:17:04] <PetefromTn_> but it is cold today.
[12:17:11] <PetefromTn_> Not supposed to warm up til mid week
[12:17:22] <PetefromTn_> when I can pour the slab and try to get this thing installed.
[12:17:26] <zeeshan> does it snow there enough
[12:17:28] <zeeshan> to need salt trucks?
[12:17:35] <PetefromTn_> sometimes
[12:18:08] <PetefromTn_> we get about four to five snow good days of snow a year here usually. This is unusual to get it this early tho.
[12:18:29] <CaptHindsight> oh I guess we did officially did get 0.1"of snow yesterday
[12:18:55] <PetefromTn_> CaptHindsight the nice thing about that super spacer is it has a nice wide base that would be easier to bolt down to the cross slide
[12:21:46] <zeeshan> so much crap to do
[12:22:00] <zeeshan> need to put winters on :/
[12:22:07] <zeeshan> oil change
[12:22:16] <zeeshan> since mr asshole rx7 takes the garage
[12:22:24] <zeeshan> i have to freeze my ass outside and do the service on the wrx
[12:22:37] <PetefromTn_> funny it does not mention the worm gear ratio or does it even have one..
[12:24:12] <CaptHindsight> http://www.shars.com/products/view/417/Super_Rotary_Index_6quot this versions is 1:90
[12:25:00] <CaptHindsight> same for the 8" http://www.shars.com/products/view/415/Super_Rotary_Index_8quot 1:90
[12:25:20] <PetefromTn_> I like where the handle is the motor would be up and out of the way for mounting.
[12:25:27] <PetefromTn_> Looks like a stout little bastard.
[12:25:55] <PetefromTn_> I could drill that base flange in the Cincinatti and put a bunch of hold down screws into it.
[12:26:32] <CaptHindsight> there might be better or more to choose from but that what I noticed from Shars
[12:27:09] <PetefromTn_> yeah there are a lot of them out there.
[12:27:32] <PetefromTn_> I don't know what mechanisms are in the super spacer that would make or break using it in this fashion
[12:27:43] <PetefromTn_> I never took my yuasa apart for anything.
[12:27:52] <PetefromTn_> I know it came with masking plates
[12:28:04] <PetefromTn_> and had the quick handle to index based on the plates.
[12:28:22] <PetefromTn_> I would just use the worm drive and motor most likely.
[12:28:50] <PetefromTn_> I have been looking at videos and photos of these homebuilt turret indexers and I am even considering making one from scratch.
[12:29:10] <PetefromTn_> I would probably make it from steel plate and tig weld it together and then finish it in the Cinci.
[12:29:37] <PetefromTn_> Again this is all pie in the sky I still have the get the basic machine working before I worry about it.
[12:30:18] <PetefromTn_> Definitely want something like that for an automatic toolchanger setup on it eventually tho.
[12:30:41] <PetefromTn_> Well I am gonna heat up the shop and try to get more work done cleaning the shop and the new lathe.
[12:40:24] <PetefromTn_> http://www.artofmanliness.com/2011/10/30/the-3-characteristics-of-an-educated-man/ interesting..
[12:45:23] <WalterN> PetefromTn_: enh, weather happens, and its always surprising and throws all the farmers off
[12:45:51] <PetefromTn_> yes indeed
[12:48:46] <WalterN> been a couple weeks since I had a saturday off of work... I should do something
[12:50:12] <WalterN> I kind of want an AMD ARM system for my personal server
[12:50:25] <WalterN> but its not released quite yet
[17:18:39] <Deejay> gn8
[19:03:26] <zee-Lathe> yay
[19:03:29] <zee-Lathe> lathe has internet
[19:04:05] <XXCoder> lol
[19:06:23] <zee-Lathe> its freezing in here
[19:06:42] <XXCoder> 67.6f here
[19:06:52] <XXCoder> gonna love my heat meter gun
[19:07:23] <XXCoder> window is 62f
[19:07:38] <XXCoder> not surpised, it sucks on seal
[19:07:40] <zee-Lathe> eheheh
[19:09:17] <XXCoder> I just bought it, it's really useful for certain uses
[19:09:37] <XXCoder> I found couple major cold air leaks so far. door to garage is freakin 43f
[19:09:45] <XXCoder> older than outside
[19:11:27] <XXCoder> er colder
[19:14:15] <zee-Lathe> lol
[19:14:22] <zee-Lathe> its 15.5 C in the garage
[19:14:25] <zee-Lathe> according to the computer
[19:14:38] <zee-Lathe> cores are at 36c
[19:18:56] <XXCoder> cool. or warm rather lol
[19:20:45] <ssi> hi
[19:21:53] <PetefromTn_> hey
[19:22:15] <XXCoder> heys
[19:22:22] <ssi> what's happening
[19:22:47] <PetefromTn_> I swear I have the best wife EVA!!
[19:22:53] <ssi> yeah?
[19:22:57] <PetefromTn_> Oh yeah
[19:23:04] <Tom_itx> no i do
[19:23:08] <PetefromTn_> the shop has been a disaster area lately
[19:23:13] <PetefromTn_> nope LOL
[19:23:28] <Tom_itx> perspective
[19:23:36] <PetefromTn_> and I just got the new Air conditioner delivered so it got even more of a disaster
[19:23:59] <PetefromTn_> today my wife helped me clean and organize the entire freakin' shop....!!!!
[19:24:13] <PetefromTn_> I mean it has NEVER been this clean and organized before.
[19:24:37] <PetefromTn_> We found room and space and things that were lost seemingly forever that I could not even believe
[19:25:33] <PetefromTn_> We got the lathe moved around even better position and I tore down my engine crane and got it put up in the attick again.
[19:26:59] <PetefromTn_> We got all the sheetmetal for it moved to where I can work on it and it is not all over the floor.
[19:27:43] <PetefromTn_> we even got all my metal stock organized and put in one place.
[19:28:00] <PetefromTn_> Now maybe I can freakin' get something done in there LOL
[19:28:41] <ssi> nice!
[19:29:06] <PetefromTn_> hows things going with your house and your hangar?
[19:29:31] <ssi> going ok... I got the swap done today with the guy in A2
[19:29:37] <ssi> so he's in A4 now and I have 1 2 3 in a row
[19:29:43] <ssi> and I took the wall down between 1 and 2
[19:29:48] <PetefromTn_> man that is some serious space
[19:29:52] <ssi> https://pbs.twimg.com/media/B1ZSGTJIUAMXZxo.jpg:large
[19:29:55] <ssi> it's AWESOME
[19:30:14] <PetefromTn_> Hey that looks just like my bandsaw
[19:30:23] <ssi> yeah pretty much
[19:30:26] <ssi> it's the grizzly 7x12
[19:30:45] <ssi> when I went up to get the hardinge, we went through harrisburg and detoured up to the grizzly showroom, and I impulse-bought a bandsaw
[19:30:50] <ssi> already had a trailer, so why not? :D
[19:31:05] <PetefromTn_> I got mine for $250.00 from a guy locally
[19:31:15] <ssi> I paid like $750 for it brand new
[19:31:27] <PetefromTn_> Its a pretty damn nice little saw really
[19:31:40] <PetefromTn_> I want to make some additions to it to be able to cut stuff easier
[19:31:54] <PetefromTn_> I made similar mods to the 4x6 I had and it worked great
[19:32:06] <zee-Lathe> ssi looks bad ass
[19:32:25] <zee-Lathe> what size is that saw
[19:32:32] <PetefromTn_> whats the shit in front of the CNC?
[19:32:47] <ssi> old control parts
[19:32:53] <ssi> and lots of the contents of my house
[19:32:53] <ssi> heh
[19:32:53] <PetefromTn_> oh okay
[19:33:02] <ssi> zee-Lathe: 7x12
[19:33:08] <zee-Lathe> ah same one i has
[19:33:25] <ssi> i like it
[19:33:26] <zee-Lathe> its just blue!
[19:33:31] <zee-Lathe> hmm
[19:33:31] <ssi> had a junky 4x6 before
[19:33:34] <ssi> 7x12 is MUCH better
[19:33:39] <zee-Lathe> im trying to hook up a webcam to my lathe computer
[19:33:39] <PetefromTn_> mines like a dark green/gray color
[19:33:44] <zee-Lathe> i wonder if it will lag things
[19:33:56] <PetefromTn_> agreed the 7x12 it ten times the saw the 4x6 is
[19:34:05] <zee-Lathe> yea the 4x6 is a pos
[19:34:13] <zee-Lathe> i sold that nonsense asap i could
[19:34:29] <PetefromTn_> I did have my 4x6 on a custom welded heavy stand I built and it was nice to not have to bend over tho.
[19:34:30] <ssi> i brought it down to the airport a couple years ago
[19:34:36] <ssi> and the casting where the hinge is broke enroute
[19:34:38] <ssi> I need to throw it away
[19:34:46] <zee-Lathe> its weird that yours doesnt have front wheels
[19:34:49] <zee-Lathe> mine has 4 wheels
[19:35:01] <PetefromTn_> I kinda wish mine only had 2
[19:35:02] <roycroft> i had a 4x6 for years
[19:35:24] <PetefromTn_> it rolls around while I am trying to cut sometimes and I have to chock the wheels.
[19:35:26] <roycroft> besides capacity and power issues, i had the hardest time getting the blade to both track right and cut straight
[19:35:42] <roycroft> i finally got a 7x12 and i agree, it's ten times the saw that a 4x6 is
[19:35:44] <roycroft> at least
[19:35:54] <PetefromTn_> yeah it takes some fiddling with it but once you get it tracking it works okay.
[19:35:57] <ssi> yyeah definitely
[19:36:09] <roycroft> i got the 7x12 from hf
[19:36:12] <zee-Lathe> fuck
[19:36:14] <roycroft> for $225
[19:36:17] <zee-Lathe> this lathe macros wont work
[19:36:21] <roycroft> it was missing the table
[19:36:26] <roycroft> and the wheels
[19:36:31] <roycroft> and the coolant pump
[19:36:34] <zee-Lathe> sorry to complain but stuff with no instructions drives me insane
[19:36:34] <zee-Lathe> :{
[19:36:41] <roycroft> i sold the 4x6 for $125
[19:36:42] <PetefromTn_> I want to make a nice wide vertical table for mine that locks onto the machine casting somehow
[19:36:54] <roycroft> and used some wheels and a pump that i had laying around
[19:37:01] <roycroft> i've never gotten around to making a table for it
[19:37:09] <roycroft> but when i do it will be a lot nicer than what comes with it
[19:37:36] <PetefromTn_> I actually am using a plywood table I made real quick when I bought it and it sucks a bit.
[19:37:57] <PetefromTn_> I need to tig weld up something nice and sturdy that burrs and chips won't catch on like the wood.
[19:38:18] <zee-Lathe> ssi
[19:38:19] <PetefromTn_> It is actually decent when cutting vertically
[19:38:23] <zee-Lathe> guess what i spent 100 bux on today
[19:38:29] <ssi> PetefromTn_: my shop down here is going to be freaking amazing when I get it set up
[19:38:31] <roycroft> i just use the end of the blade guide for now when i use it vertically
[19:38:33] <ssi> zee-Lathe: wat
[19:38:35] <roycroft> it's about 1.5" square
[19:38:37] <zee-Lathe> 20lb fire extinguisher
[19:38:38] <zee-Lathe> finally!
[19:38:41] <ssi> good plan
[19:38:45] <roycroft> plenty of surface to support the work :P
[19:38:45] <ssi> i'm going to buy a couple myself :P
[19:38:47] <zee-Lathe> 10 year warranty on discharging
[19:38:59] <zee-Lathe> unlike that other pos
[19:39:07] <zee-Lathe> and rechargeable
[19:41:01] <PetefromTn_> Yeah man I am sure it would be.
[19:41:45] <PetefromTn_> Honestly I am jealous you have that much space. The only thing I can say for my shop tho is despite its size I can heat and cool it and make it quite comfortable in there while I am working
[19:42:03] <ssi> yeah
[19:42:10] <ssi> I have more trouble with that
[19:42:33] <PetefromTn_> We worked out there all day long today cleaning and even when we opened the doors to blow out a couple years worth of dust I was comfortable despite it being pretty cold outside.
[19:43:11] <PetefromTn_> Usually during the winter months I will go out there and turn on that forced air heater and let it run for like a half hour or so or at least until the thermostat shuts it off.
[19:43:29] <PetefromTn_> Then I take my electric 220v heater and plug it in to maintain the heat.
[19:43:43] <zeeshan> man
[19:43:48] <zeeshan> how the hell do i find this solenoids polarity
[19:43:48] <PetefromTn_> It stays pretty comfy out there to the point I can wear a tee shirt even when it is super cold outside
[19:43:50] <zeeshan> without guessing
[19:44:07] <zeeshan> i mean if its like an injector
[19:44:11] <zeeshan> that polarity shouldnt pattern
[19:44:14] <zeeshan> just like a relay
[19:45:19] <PetefromTn_> Been sorting thru the sheetmetal for the CNC lathe and trying to figure out how it goes together and what pieces I am missing.
[19:45:27] <PetefromTn_> It's like a freakin' puzzle.
[19:45:32] <zeeshan> hahaha
[19:45:39] <zeeshan> was it all apart when you got it?
[19:45:48] <zeeshan> some of mine were out
[19:45:50] <PetefromTn_> the sheetmetal for the top enclosure was
[19:45:53] <zeeshan> and i have no clue where they go
[19:46:02] <PetefromTn_> I know for a fact that the back guard is missing
[19:46:15] <PetefromTn_> and I am not entirely sure how the whole rear part goes together
[19:47:05] <PetefromTn_> the parts I do have look to be in great shape tho with no apparent damage anywhere
[19:47:42] <PetefromTn_> I need to run down and get some maybe 4" diameter steel tubing to make the pendant arm assembly
[21:05:13] <PetefromTn_> http://knoxville.craigslist.org/tls/4710391736.html Speaking of 7x12 bandsaws. I just saw this one on craigslist and noticed the add on jaws for the original jaws that extend right up to the blade. Not a bad idea really
[21:09:12] <PetefromTn_> another good idea I saw and did on my 4x6 was to drill and tap the side of the movable jaw away from the blade for like an acme screw or allthread rod. This way you can clamp up short pieces without having to shim up or put a block in the other end to keep the jaw from twisting. I have not done that yet on my 7x12 but I plan to soon.
