[01:18:09] <tjb1> Its going to "Somewhere, PA"
[01:24:19] <_ink> haha
[01:26:58] <Jymmm> Um, why?

[10:40:41] <r00t4rd3d> adam savage tool box
[10:40:46] <r00t4rd3d> i think i might make one
[10:43:42] <archivist> there is a danger the box will be heavier than the tools
[10:45:40] <r00t4rd3d> seems like it made from very thin metal

[10:50:42] <IchGuckLive> hi all B)
[10:50:52] <JT-Shop> hi
[10:55:52] <IchGuckLive> nice and warm here in germany no rain for weks
[10:58:03] <IchGuckLive> i can not find long full radius (Ball end cutters in the past there where alover for copy cuttings now as the mold systems have changed and HSC is in all minds noone seams to produce this cutters anymore
[11:07:53] <r00t4rd3d> ebay man
[11:11:22] <r00t4rd3d> ball end mill long
[11:11:34] <r00t4rd3d> on ebay give me lots of result for long ball ends
[11:33:40] <taiden> is there any way to make the estop trigger if there is an RTAPI error?
[11:34:18] <taiden> while i wait for my d525 to arrive, my machine has a hilarious tendency to not only fail on the last part, but to also take out previous parts in it's path
[11:34:49] <taiden> (unexpected realtime delay error)
[11:35:14] <r00t4rd3d> you would have to do some coding to make that happen
[11:35:27] <JT-Shop> trigger an external e-stop?
[11:35:53] <r00t4rd3d> just tail dmesg and watch for the error and hit stop manually
[11:36:05] <r00t4rd3d> tail -f /var/log/dmesg
[11:36:15] <r00t4rd3d> in a terminal and watch for the error
[11:36:47] <taiden> yep
[11:36:48] <taiden> alright
[11:36:59] <r00t4rd3d> or hit pause
[11:37:01] <t12> is there a programmatic way to shut down the job
[11:37:10] <taiden> i'm wondering if you can do it automatically
[11:37:13] <taiden> but if not i will just watch the cut
[11:37:52] <JT-Shop> I thought LinuxCNC shut down when a bad enough realtime delay occoured
[11:38:19] <r00t4rd3d> i think thats his problem
[11:38:39] <r00t4rd3d> or part of it
[11:38:56] <r00t4rd3d> using a shitty pc is the main problem :)
[11:39:00] <t12> it wasnt what you determined the other day?
[11:39:07] <t12> about inputting some wrong paramter
[11:39:23] <taiden> nope
[11:39:30] <taiden> this computer is just f**kd
[11:39:34] <taiden> imo
[11:39:37] <t12> checked the disk thing?
[11:39:49] <taiden> d525 is on the way
[11:39:49] <r00t4rd3d> did you order some memory too?
[11:39:50] <t12> it didn't do this previously you said? or has this machine always done that
[11:39:57] <taiden> it just randomly started
[11:40:11] <taiden> i ordered a d525 because i just can't afford for this to happen anymore
[11:40:21] <taiden> but for the next few days i need to keep cutting as best as i can
[11:40:22] <r00t4rd3d> did you reinstall everything?
[11:40:36] <t12> did you check smart for the hard drive?
[11:40:54] <taiden> what is smart?
[11:40:59] <r00t4rd3d> or use nvidia drivers
[11:41:00] <t12> internal hard drive diagnostics/reporting
[11:41:05] <t12> smartctl -a /dev/sda should spit them out
[11:41:09] <t12> in your case
[11:41:38] <taiden> 'smartctrl is currently not installed
[11:41:47] <t12> install it? which distro
[11:41:48] <tjb1> I didn't realize how small the oldham coupler with a 3/8" bore was going to be
[11:41:51] <Jymmm> -r
[11:41:53] <taiden> hardly heron
[11:42:26] <taiden> there isn't a way to set up realtime delay as an estop trigger with ladder logic or w/e it's called?
[11:42:28] <t12> or is linuxcnc distributed ad its own thing
[11:42:47] <taiden> fresh install from 8.04 linuxcnc live cd
[11:42:58] <taiden> with update to firefox and linuxcnc only
[11:43:03] <taiden> everything else is totally untouched
[11:43:13] <taiden> was using nv drivers and it worked fine, then a few days ago it started diong this
[11:43:20] <Jymmm> taiden: do you care if the pc is shut down itf it happens?
[11:43:50] <taiden> switched to vesa as a last ditch effort, dropped the latency spikes about 1/2 but still apparently high enough to make me miss 3 inches worth of steps
[11:43:54] <taiden> that's fine
[11:46:29] <t12> if its on net, just install the smartmontools package
[11:46:34] <t12> that will incldue smartctl
[11:46:47] <t12> do disabled smartd if it tries to start it at boot
[11:47:02] <t12> i dont know if that will interfere with the rt stuff or not at runtime
[11:47:55] <t12> and can you put the outputs of cat /proc/interrupts and lspci -v somewhere?
[11:50:54] <Jymmm> taiden: You can use denyhosts to monitor dmesg then send a command to shutdown linuxcnc
http://denyhosts.sourceforge.net/index.html
[11:51:57] <r00t4rd3d> it will probably be too late by the time that happens
[11:52:45] <r00t4rd3d> in 10 seconds lots of shit can be messed up
[11:56:11] <joe9> what is a reasonable value for 'step down" for a pcb FR4 material?
[11:56:27] <joe9> djdelorie: any thoughts, please?
[11:56:44] <joe9> i remember that you used to use 0.04 for some materials.
[11:56:55] <djdelorie> "step down" ?
[11:56:56] <joe9> not sure what would be good/ideal for FR4 pcb material.
[11:57:08] <joe9> i mean in the "pocket operation" for
[11:57:11] <joe9> gcode
[11:57:45] <djdelorie> I haven't milled fr4 yet, that was for drilling
[11:57:51] <djdelorie> 40 mil sounds right though
[11:57:59] <joe9> even for FR4?
[12:14:52] <jdh> tail -f ,grep,expect, halcmd?
[12:21:16] <djdelorie> joe9: checked my scripts, I use G81 with F40 for drilling FR4 but I don't recall if that's the "works" case or if it's one of the "eventually breaks drills" case. I suspect F20 or F30 is safer
[12:21:54] <djdelorie> last time I did it, I was still testing and benchmarking, not doing production
[12:26:12] <joe9> djdelorie: thanks a lot.
[12:26:38] <joe9> I use a Feed rate of 6
[12:28:15] <jdh> I like 5)
[12:31:07] <joe9> jdh: any particular reason?
[12:31:25] <IchGuckLive> tool efecience
[12:31:40] <IchGuckLive> less is more
[12:31:49] <joe9> jdh: oh, really?
[12:31:54] <joe9> so, 3 is better than 6?
[12:32:02] <joe9> I thought Feed rate is inches per minute
[12:32:11] <joe9> and the more it is, the faster work gets done.
[12:32:12] <IchGuckLive> no 3 is to low
[12:32:22] <jdh> I like 5. and 10
[12:32:28] <IchGuckLive> calculate on teeth and material
[12:32:43] <IchGuckLive> chip not scrap
[12:33:08] <IchGuckLive> chip thick at 0.02mm
[12:33:14] <IchGuckLive> min
[12:35:46] <joe9> alex4nder: ReadError_ : what feed rate are you using?
[12:38:32] <archivist> joe9, there are plenty of online calculators, depends on chip per tooth, material and spindle rpm, number of cutting edges on tool
[12:39:29] <jdh> and fondness for round numbers
[12:39:30] <archivist> and is your machine and work piece up to the limits given by those calculations
[12:40:33] <archivist> and .....does one take into account the lesser cut towards the middle of the tool :)
[12:41:53] <archivist> too much bite on a long tool and you will have bending and grabbing
[12:43:51] <Loetmichel> re @ home
[13:08:47] <taiden> what do you d525 guys use for a distro
[13:08:50] <taiden> 10 or 8?
[13:09:04] <pcw_home> 10
[13:09:49] <IchGuckLive> 10
[13:10:12] <IchGuckLive> taiden: did it work today
[13:10:25] <IchGuckLive> 17+ hr
[13:10:39] <taiden> IchGuckLive: nope
[13:10:47] <taiden> IchGuckLive: I ordered a d525
[13:10:48] <IchGuckLive> not good
[13:10:57] <taiden> IchGuckLive: I can only assume it's old PC hardware getting older
[13:11:12] <IchGuckLive> you solved the smi problem on your P4 SNI at 10.04
[13:11:12] <taiden> IchGuckLive: I just need something that works and so I decided to go with the d525
[13:11:28] <taiden> i have tried 10.04 on this computer and it was worse :(
[13:11:54] <IchGuckLive> so you are on hardy
[13:12:20] <IchGuckLive> then all is worse go d525 and start over
[13:12:32] <taiden> yep
[13:12:41] <taiden> hopefully it will all arrive before the weekend!
[13:12:47] <taiden> and then I can be ready for Monday
[13:15:06] <IchGuckLive> taiden: what modues are loaded in your "rtapi.conf "
[13:15:45] <IchGuckLive> is it a standard 3Axis router
[13:15:45] <taiden> i dont know how to check
[13:16:09] <IchGuckLive> open terminal and find the file
[13:16:36] <IchGuckLive> lsmod | grep rtai <- on the Hardy PC
[13:17:11] <taiden> it doesn't show directory
[13:17:53] <L84Supper> taiden: what exactly is not working with your d525? Just wondering since I heard that many here use them.
[13:17:59] <IchGuckLive> to find the file "sudo find / -iname 'rtapi.conf'"
[13:18:25] <IchGuckLive> L84Supper: he has none yet
[13:18:40] <IchGuckLive> D525 is the board of choice
[13:18:50] <L84Supper> oh, ok, it's not working on his old hardware
[13:19:05] <IchGuckLive> no he has orderd one
[13:19:16] <IchGuckLive> did not arive yet
[13:19:28] <IchGuckLive> he is on hardy at P4
[13:20:18] <L84Supper> IchGuckLive, I haven't used anything Intel with LinuxCNC
[13:20:31] <IchGuckLive> i agree no intell
[13:21:26] <Jymmm> Has anyone made or dealt with dies/shoes for a punch press by chance?
[13:22:01] <IchGuckLive> punch press is SPS
[13:22:08] <IchGuckLive> no linuxcnc
[13:22:08] <Jymmm> ?
[13:22:32] <Jymmm> IchGuckLive: ?
[13:22:45] <IchGuckLive> punch press control on linuxcnc i am wright
[13:22:54] <IchGuckLive> why
[13:23:17] <Loetmichel> IchGuckLive: so what?
[13:23:21] <IchGuckLive> Neumatic and SPS control ARduino if you like
[13:23:53] <IchGuckLive> Loetmichel: servus
[13:23:58] <Jymmm> wth are you babbling about?
[13:24:23] <Loetmichel> and if you have no phantasy to imageine a modified punch pres to a CNC nibbler...
[13:24:29] <Loetmichel> ;-)
[13:24:29] <IchGuckLive> i think i missunderstand your question for my bad english
[13:24:53] <Jymmm> there are cnc punch presses btw
[13:25:03] <taiden> Jymmm: no I haven't, but I really need to make a 1.750 punch press
[13:25:07] <taiden> manually operated
[13:25:14] <taiden> so if you learn anything please let me know
[13:25:26] <Jymmm> 1.75 what, bannanas?
[13:25:33] <taiden> yes
[13:25:36] <taiden> smoots really
[13:25:40] <Jymmm> O_o
[13:25:40] <taiden> i punch out 1.750" holes in stainless mesh
[13:25:55] <taiden> local place wants to charge me $1.70 per punch
[13:25:55] <Loetmichel> taiden: how fine a mehs?
[13:25:56] <Jymmm> wire mesh?
[13:25:59] <taiden> yes
[13:26:03] <Jymmm> buy em
[13:26:06] <taiden> it's 0.028" 8x8 (smoots)
[13:26:13] <Loetmichel> ouch
[13:26:15] <Jymmm> wth is a smooth
[13:26:18] <Jymmm> smoot
[13:26:22] <Loetmichel> that will be not so easy
[13:26:23] <taiden> look it up, it's a hilarious story
[13:26:29] <taiden> i could only find precut ones in fine mesh for filtering
[13:26:29] <Jymmm> no thanks
[13:26:47] <taiden> you're missing out on one of the most well known engineering / units of measurement related stories
[13:26:51] <Jymmm> I found all sizes
[13:26:51] <Loetmichel> the finer the mesh the more precise the punch die must be
[13:26:55] <taiden> shows up in a lot of physics texts
[13:28:16] <IchGuckLive> taiden: here its 20cent per punch not under 10euros
[13:28:29] <Jymmm> taiden: Take your choice...
http://www.twpinc.com/wire-mesh/TWPCAT_12
[13:28:32] <taiden> that is a fair price
[13:29:18] <taiden> buying the mesh isn't the problem
[13:29:28] <taiden> getting it cut to a 1.75" circle is
[13:29:29] <IchGuckLive> im off By
[13:29:57] <Connor> for what?
[13:30:04] <Jymmm> taiden:
http://www.twpinc.com/wire-mesh/DISC_STAINLESS_STEEL/p_008X008S0320W48T_DK
[13:30:08] <taiden> oh wait i just found that
[13:31:18] <Jymmm> s7¢
[13:31:22] <Jymmm> 27¢
[13:31:30] <taiden> where do you find 27 cents?
[13:31:37] <taiden> they want to charge me $6 a piece for a qty 25 order
[13:31:53] <Jymmm> 17¢ for 10000
[13:32:00] <Jymmm> 27¢ for 1000
[13:32:30] <Jymmm> $1.50 for 100
[13:32:44] <taiden> oic
[13:32:58] <taiden> local place is $1.70 for 25 qty
[13:33:04] <taiden> identical mesh
[13:33:09] <taiden> that doesn't seem so bad anymore LOL
[13:33:19] <Connor> taiden: What is this for?
[13:33:53] <taiden> http://vibrolabs.com
[13:34:12] <r00t4rd3d> Canon is really starting to piss me off
[13:34:28] <taiden> forgive the slow loading times
[13:34:38] <taiden> i haven't optimized image sizes yet
[13:35:28] <r00t4rd3d> you make those?
[13:35:31] <taiden> yes
[13:35:35] <Connor> What kind of wood is that ?
[13:35:35] <taiden> this is why i need my cnc to run haha
[13:35:50] <taiden> there are two types of wood pictured, one is honduran mahogany and the other is curly maple
[13:36:08] <Jymmm> taiden: WTF no hawaiian koi?!
[13:36:18] <taiden> i have a chunk here that i am looking into ;)
[13:36:34] <r00t4rd3d> you sell alot of those?
[13:36:53] <Jymmm> taiden: No cocobolo?!
[13:37:01] <Jymmm> taiden: you cheap bastard!
[13:37:15] <Jymmm> lol
[13:37:42] <taiden> cheap?
[13:37:49] <taiden> this honduran mahogany is $15 a board foot
[13:38:01] <Jymmm> Like I said, cheap bastard!
[13:38:08] <taiden> hahaha
[13:38:28] <Jymmm> cocobolo is $40 BF
[13:38:29] <taiden> i've thrown away ~ a board foot today in failed attempts to cnc
[13:38:44] <taiden> that makes no sense because amboyna burls are about $20 a bf
[13:38:49] <taiden> $20-30
[13:39:03] <taiden> if you buy cocobolo at rockler it's probably $80 a bf though haha
[13:39:20] <Jymmm> and hawaiian koi is just obscene
[13:39:38] <taiden> i have this awesome piece of koa
[13:39:48] <taiden> it's not especially curly but
[13:39:55] <taiden> it's an offcut from a limb
[13:40:03] <taiden> has about 1.5" wide heartwood
[13:40:11] <taiden> and a 1" sapwood surruonding it
[13:40:18] <taiden> idk how it's going to come out but im interested to find out
[13:42:23] <Jymmm> taiden: And no Kauri either,
[13:42:50] <taiden> hey Jymmm
[13:43:06] <taiden> name all the woods you want and i'll list them but min qty 5 and you have to pay up frnot
[13:43:33] <Jymmm> taiden: You need to stop buying this cheap ass < $20 BF crap you got from walmart, m'kay!
[13:45:04] <taiden> hahaha
[13:45:18] <taiden> I use honduran mahogany because it's very good and easy to work with
[13:45:31] <Jymmm> cheap AND lazy bastard I see
[13:45:37] <taiden> and i dont have the time to handle many variations
[13:45:54] <taiden> the Limiteds will include some of the woods you listed
[13:46:00] <taiden> and be priced to match LOL
[13:46:06] <Jymmm> taiden:
http://www.ancientwood.com/catalog/small-blocks/block-0017
[13:46:22] <Jymmm> cracked though
[13:46:52] <Jymmm> taiden: But not bad to play with for 10,000+ year old wood =)
[13:47:07] <taiden> what the hell is that?
[13:47:17] <taiden> is that petrified?
[13:47:18] <Jymmm> taiden: Ancient Kauri
[13:47:23] <Jymmm> no
[13:47:33] <taiden> it's a good size
[13:47:41] <taiden> my blanks are 3x3x1.5
[13:47:49] <taiden> i could fit quite a few in that chunk
[13:48:04] <Jymmm> taiden:
http://en.wikipedia.org/wiki/Ancient_Kauri
[13:48:25] <Jymmm> ok 2 to 50 thousand yo
[13:49:29] <taiden> is there any way to call the home function
[13:49:35] <taiden> from ngc
[13:49:37] <taiden> ?
[13:50:53] <taiden> i'd like to be able to call it when cutting multiple parts on a fixture
[13:54:46] <taiden> i want ancient kuri now
[13:54:56] <taiden> any other notable woods?
[13:55:27] <Jymmm> taiden: You are too cheap and lazy bastard to even think of offering it!
[13:55:39] <Jymmm> ;)
[13:55:45] <taiden> it would be perfect for a Limited!
[13:55:53] <Jymmm> taiden: go back to wallyworld where you came from!
[13:56:04] <taiden> haha
[13:56:15] <taiden> expletiveing Jymmm!
[13:56:23] <taiden> $15 bd ft is not trivial!
[13:57:13] <taiden> i think that i would like to figure out how to add estop on latency error
[13:57:22] <taiden> and then commit it to development version of linuxcnc
[14:16:10] <Jymmm> taiden: maybe a python script that hooks into cl
[14:16:40] <taiden> that's what i was thining
[14:17:03] <Jymmm> or a wrapper script that starts emc from a terminal
[14:17:07] <taiden> any thoughts on calling the homing function?
[14:17:19] <Jymmm> nope
[14:17:19] <cradek> pretty sure motion has a last-period-took-this-long hal output
[14:17:33] <Jymmm> there ya go!
[14:17:34] <cradek> thresholding that would be utterly trivial
[14:17:45] <cradek> if it's a param you'd have to change it to a pin
[14:17:46] <taiden> cradek where would i start to look into that
[14:17:52] <taiden> im totally unfamiliar with hal and cl
[14:18:06] <Jymmm> (and wood too)
[14:18:06] <cradek> brb
[14:18:14] <taiden> jokes
[14:18:19] <taiden> Jymmm's got them
[14:18:23] <Jymmm> nuh uh
[14:18:49] <taiden> as long as I knwo more than my customers I'm good to go right? haha
[14:19:08] <Jymmm> next thing you know you'll try to use ss wire mesh for shields. eeeesh
[14:19:18] <taiden> shields?
[14:19:30] <Jymmm> protection shields from fat fingers
[14:19:34] <taiden> haha
[14:19:48] <taiden> i actually use it for dust capture
[14:20:05] <taiden> my entire cnc router is contained within a ss wire mesh box
[14:20:05] <Jymmm> O_o
[14:20:16] <taiden> with a shop vac for negative pressure
[14:20:17] <Jymmm> the discs?
[14:20:22] <taiden> yes
[14:20:35] <Jymmm> you lined you cnc with 1.75" discs?
[14:20:42] <taiden> doesn't everyone?
[14:20:50] <Jymmm> * WHACK *
[14:21:00] <taiden> you jealous?
[14:21:15] <taiden> my mdf router sucks
[14:21:37] <taiden> formaldehyde based bearings get warm
[14:21:39] <Jymmm> hardly, I have ss screen layered on clear vinyl with grounding points!
[14:21:58] <Jymmm> ground straps
[14:22:05] <taiden> jymmm waht are you running for a cnc machine?
[14:22:31] <Jymmm> toaster and a hf cordless drill
[14:22:38] <taiden> that thing must cook
[14:22:52] <Jymmm> just burns stuff
[14:23:08] <taiden> no but seriously
[14:23:14] <taiden> i need ideas for my next router
[14:23:22] <taiden> i want to start slowly collecting parts to build another
[14:23:24] <taiden> this one is crap
[14:23:25] <Jymmm> 24x24x6 gantry router
[14:23:38] <taiden> did you use plans or self design or purchased?
[14:23:47] <Jymmm> bought frame
[14:23:53] <taiden> cncrouterparts?
[14:23:55] <Jymmm> 8020 based
[14:23:58] <Jymmm> no
[14:24:21] <taiden> you aren't a very forthcoming individual are you?
[14:24:31] <Jymmm> not with it, no.
[14:24:35] <taiden> why not?
[14:24:42] <Jymmm> headaches
[14:24:58] <taiden> my cnc router is responcible for about 30 of mine
[14:25:17] <Jymmm> 4000 of mine
[14:25:21] <taiden> fair enough
[14:25:29] <Jymmm> @ $1/ea
[14:25:33] <taiden> ouch
[14:25:37] <taiden> i have $1300 into mine total
[14:25:41] <Jymmm> NOW you get it
[14:25:50] <taiden> i want a 18x18x4
[14:25:53] <taiden> mine is floppy
[14:25:56] <taiden> thrown together
[14:26:03] <taiden> 12x10.5x3
[14:26:21] <taiden> had about 5 thou backlash on x and y
[14:26:24] <taiden> has*
[14:26:27] <Jymmm> Fine, you can buy mine =)
[14:26:48] <taiden> what are your thoughts on timing belt based motion?
[14:27:05] <Jymmm> replace every 50,000 miles
[14:27:20] <taiden> all mine have been interference engines
[14:27:28] <taiden> so they do about 200,000
[14:27:36] <taiden> and then eventaully i have to call AAA
[14:46:29] <Jymmm> taiden: AAA?! Gawd you really are a cheap lazy bastard. You need one of these... www.youtube.com/watch?v=AuL7cOO6EfY
[14:46:40] <Jymmm> http://www.youtube.com/watch?v=AuL7cOO6EfY
[14:57:50] <Jymmm> taiden: What is this finished with?
[14:57:54] <Jymmm> http://vibrolabs.com/wp-content/uploads/2012/08/limited-002-4.jpg
[14:59:05] <archivist> better be linseed oil for teh purity
[14:59:43] <Jymmm> it doesn't look like a hand rubber oil finish, but I could be mistaken.
[14:59:49] <Jymmm> rubbed
[15:02:14] <taiden> it's boiled linseed
[15:02:20] <taiden> then amber shellac
[15:02:23] <taiden> then lacquer
[15:02:30] <taiden> then polish then beeswax
[15:02:37] <taiden> although next time i will skip the beeswax
[15:02:46] <taiden> the finish didn't come out well on that one so i kept it myself
[15:02:52] <Jymmm> any idea on how I could ghetto together a punch and die for a rectangular slot?
[15:03:04] <Jymmm> taiden: did you take a torch to the wax?
[15:03:25] <archivist> buy a pair form a punch and die maker
[15:03:30] <archivist> from
[15:04:00] <Jymmm> archivist: is that custom made or off the shelf? All I'm seeing are meant for big presses
[15:04:53] <archivist> forces are high when punching, presses are large
[15:05:45] <Jymmm> I just want a slot in shim stock, so I don't need a 60 ton punch/die
[15:06:16] <t12> lol man
[15:06:17] <Jymmm> 0.050 x 0.625"
[15:06:18] <t12> audiophiles
[15:06:37] <archivist> that is spelled audiophools
[15:06:50] <Jymmm> 2mm x 13mm fwiw
[15:07:33] <Jymmm> in 0.010" ss
[15:07:34] <archivist> define shim
[15:07:50] <Jymmm> 10mil 302-2B
[15:07:54] <archivist> photo etch
[15:08:05] <taiden> audiophiles are a lovely bunch
[15:08:09] <taiden> very appreciative
[15:08:43] <taiden> Jymmm: I did not take a torch to the wax, had considered that.
[15:09:08] <taiden> i did attempt a heat gun though, although i was very careful so it seemed to have no effect
[15:09:27] <Jymmm> s/appreciative/high limit credit cards/
[15:09:52] <taiden> s/high limit credit cards/appreciated with high limit credit cards/
[15:09:56] <taiden> appreciative
[15:10:08] <archivist> Jymmm,
http://www.wisetool.com/formular/formula.htm will give you force needed
[15:11:41] <taiden> alright
[15:11:46] <taiden> made enough parts for today
[15:11:55] <taiden> going to go upstairs and enjoy the sun and spray some poly!
[15:12:07] <taiden> thanks all for the help
[15:14:56] <archivist> if you design the tooling to cut like scissors then the force will be reduced but work holding may will become very important
[15:24:35] <Jymmm> I found this
http://roperwhitney.com/tech/chart4-5.cfm but unlike a hole where I could just use a drill bit to drill into a plate for the "die", then flip the bit over to use as a "punch" in a drill press, I need a "rectangular hole"
[15:26:43] <FinboySlick> rectangular and not square?
[15:26:48] <Jymmm> I just need to do about 100 slots, so the most manual way will be fine for now
[15:27:09] <Jymmm> 0.050" x 0.625" slot
[15:27:13] <archivist> photo etch for the nth time
[15:27:27] <Jymmm> archivist: I cna't use acids.
[15:27:53] <archivist> get a professional to do it!
[15:28:04] <FinboySlick> How thick is the material?
[15:28:13] <Jymmm> 0.010" 302 SS
[15:28:41] <Jymmm> 10mil
[15:28:53] <FinboySlick> Get a Trumph TruPunch 2020
[15:28:59] <Jymmm> lol
[15:29:08] <FinboySlick> Ebay, man.... Ebay.
[15:29:38] <Jymmm> I just need to prototype a few is all
[15:30:01] <Jymmm> I already have waterjet and punch press places for the larger qtys
[15:30:36] <archivist> use them for prototypes too, then you get real prototypes
[15:30:53] <Jymmm> archivist: $123 ea in qty of 10 or less.
[15:31:04] <Jymmm> again, I need to do this in house
[15:31:09] <archivist> real development costs
[15:32:28] <archivist> who is paying my irc time to help you make a profit
[15:33:59] <Jymmm> archivist: You're welcome to ignore me if you like.
[15:47:11] <jdh> so. I ordered another 20lb piece of 1.5" drill rod from amazon since they delivered an empty box last time (price went up $9). Today, I got an empty tube.
[15:47:47] <FinboySlick> jdh: That's pretty bad.
[15:47:48] <cradek> fool you twice, shame on you
[15:48:25] <FinboySlick> jdh: Maybe they cap the box/tube with thin paper and the drill rods fall through? ;)
[15:48:43] <jdh> FinboySlick: yep
[15:49:08] <jdh> last time it was a box though. corner gave out. This time it was a thin piece of paper tape over the bottom of the tube.
[15:53:33] <FinboySlick> jdh: Makes me wonder where the rods fell along the way.
[15:56:05] <jdh> this one is probably on the first truck it went out on. 36" rod, 38" shipping tube. Single layer of paper tape
[15:56:13] <tjb1> Jymmm: He won't budge on the price of the chiller or shipping
[15:56:25] <Jymmm> tjb1: ?
[15:56:31] <tjb1> The G540 chiller
[15:57:01] <Jymmm> hI would't use one anyway, a slab of al will always work
[15:57:03] <tjb1> Not gonna pay $60 for 2 fans on a circuit board
[15:57:24] <Jymmm> fans fail
[15:57:34] <Jymmm> heatsink failure is RARE
[15:58:25] <jdh> Marris disagrees
[15:58:53] <Jymmm> I mean MELTING of the heatsink as the failure =)
[15:59:02] <tjb1> Jymmm: What do you think of these?
http://www.mcmaster.com/#4146T18
[16:11:18] <jdh> https://docs.google.com/a/hudsons.org/file/d/0Bz5kbenmrw4VN0owSkRsbVRTUFU/edit#
[16:12:41] <tjb1> amazon supply?
[16:12:54] <jdh> that would be a misnomer at best.
[16:17:22] <tjb1> jdh -
http://www.mcmaster.com/#4146T18
[16:17:50] <jdh> err... they are lovel?
[16:17:56] <jdh> lovely? or levely anyway
[16:18:13] <tjb1> Not too expensive either
[16:20:23] <DJ9DJ> gn8
[16:23:30] <tjb1> How much is Epoxy-Granite
[16:23:58] <Jymmm> cultured marble?
[16:24:46] <jdh> depends on what you make it out of, how much epoxy, how much granite
[16:34:06] <tjb1> So its basically just rock, sand and epoxy
[16:35:24] <alex4nder> joe9: feedrates depend a lot on material
[16:35:53] <Jymmm> tjb1: and a heatsink
[16:36:05] <tjb1> heatsink?
[16:41:24] <tjb1> btw, that one you linked is about an inch too long and 2-3 inches too wide
[17:04:31] <tjb1> Jymmm: Whats the tape used for heat sinks
[17:04:41] <tjb1> !seen WillenCMD
[17:04:41] <the_wench> last seen in 2012-08-19 20:29:24GMT 98:23:47 ago, saying Read error: Connection reset by peer
[17:05:14] <JT-Shop> duct tape
[17:06:08] <tjb1> :/
[17:10:08] <tjb1> You don't use duct tape
[17:30:28] <Jymmm> heat sink grease?
[17:31:00] <Jymmm> !seen diety
[17:31:00] <the_wench> Never heard of the entity diety you ask for
[17:33:36] <tjb1> I don't think that is going to hold a sink of that size
[17:34:05] <Jymmm> you NEVER use adhesive to secure a heatsink.
[17:34:26] <Jymmm> you use mechanical fastener f some sort; typically spring loaded
[17:35:07] <Jymmm> coefficient of thermal expansion
[17:35:15] <tjb1> Well that is going to be complicated :)
[17:36:25] <JT-Shop> come on Jymmm use some red duct tape
[17:52:54] <JT-Shop> why does my dell fall asleep and not wake up
[17:53:11] <Tom_itx> you got a lazy one
[17:53:44] <Tom_itx> i dunno, i have 3 laptops sometimes i have to hit the pwr button to wake them
[17:54:10] <Tom_itx> garage door all fixed now
[17:54:18] <JT-Shop> this is a desktop one
[17:54:21] <Tom_itx> had to replace all the pulleys on the springs
[17:54:42] <Tom_itx> not sure
[17:54:46] <jp__> hey all
[17:54:50] <Tom_itx> i'd turn it off in the bios if at all possible
[17:55:31] <jp__> can you do a g31 on a rotary axis?
[17:57:52] <JT-Shop> what is g31?
[17:58:10] <jp__> probe/skip i thought
[17:58:27] <JT-Shop> might want to look that one up in the manual?
[17:59:06] <jp__> yeah never tried but got an app where it would be useful
