[00:05:44] <MacGalempsy> anyone know what controls motion.spindle-on?
[00:06:10] <XXCoder> awesome
[00:06:11] <Wolf_> spindle enable?
[00:06:17] <XXCoder> managed to see moon fully eclipsed.
[00:06:26] <MacGalempsy> I try to setp motion.spindle-on and it says it already has writers. does anyone know if the machine has to be homed to get spindle-enable = true?
[00:06:30] <pcw_home> man motion
[00:07:11] <MacGalempsy> ?
[00:07:27] <pcw_home> the motion manual page
[00:07:57] <MacGalempsy> ok
[00:08:20] <pcw_home> motion.spindle-on is the _output_ pin from motion thats designed to control the spindle
[00:08:48] <pcw_home> you cannot setp it since its an output
[00:12:23] <pcw_home> pncconf has 2 spindle related bugs:
[00:12:24] <pcw_home> http://sourceforge.net/p/emc/bugs/433/
[00:14:07] <sector_0> what do you guys think of a machine like this...
[00:14:08] <sector_0> http://www.ebay.com/itm/CNC-Metal-Motorized-Mini-Milling-Machine-DIY-Woodworking-Power-Tools-Machinery-/281436614830?hash=item4186edf0ae
[00:14:49] <Wolf_> lol toy?
[00:15:44] <sector_0> I'm looking for something small and not too expensive
[00:16:24] <sector_0> but the other things that I'm finding are >USD$500
[00:16:28] <XXCoder> sector_0: be sure its workspace is large enough for you
[00:16:35] <XXCoder> that looks... tiny.
[00:16:50] <sector_0> XXCoder, workspace is about 90mmX90mm
[00:17:05] <XXCoder> 3.5 inch approx
[00:17:16] <sector_0> which isn't too bad for me at this point
[00:18:20] <sector_0> I'm more worried about rigidity issues
[00:18:46] <sector_0> you guys might have more experience with machine than I have
[00:19:12] <sector_0> how rigid does it look/
[00:19:12] <sector_0> ?
[00:19:35] <XXCoder> no idea, not much experence too
[00:20:28] <Wolf_> I would rather buy a bunch of taig parts and build something before getting that thing
[00:21:45] <sector_0> Wolf_, taig?
[00:22:30] <Wolf_> http://www.taigtools.com/mmill.html
[00:23:06] <Contract_Pilot> www.ebay.com/itm/401000660423
[00:24:06] <Wolf_> http://www.cartertools.com/catalog.html you can get much of it in parts
[00:24:43] <Contract_Pilot> http://www.stevenrhine.com/wp-content/uploads/2015/09/Lightmachines-Lathe-Mill-.jpg
[00:25:29] <Wolf_> heh, that turning center looks like a fun project
[00:25:40] <Contract_Pilot> Both will be.
[00:26:14] <Contract_Pilot> Mill cleaned up well. http://www.stevenrhine.com/wp-content/uploads/2015/09/Spectralight-LightMachines-Sherline-New-Steppers1.jpg
[00:26:36] <Wolf_> nice
[00:26:56] <Contract_Pilot> I may off the turn center not sure
[00:27:02] <MacGalempsy> pcw_home: right now I am using output-8 to send the 24v to enable the spindle. is it beter to use the SPINENA?
[00:27:27] <Contract_Pilot> I am in to bartering.
[00:28:04] <Contract_Pilot> Love trading some times i score some times the other's score but as long as both walk away happy thats all that matters
[00:30:59] <diginet> does anyone here have any experience with LVDTs?
[00:32:17] <Contract_Pilot> Trying to figure out what all i will need extra for LCNC
[00:33:03] <Contract_Pilot> May order a cheap china bob off ebay use a PS Some drivers and see if I can make a small box for the small mill.
[00:36:43] <diginet> specifically, is it something you could realistically make yourself?
[00:43:07] <Contract_Pilot> hahah soom goof offerd 60.00 for my control arms that wouold barly cover the shipping.
[00:45:14] <Contract_Pilot> http://i.ebayimg.com/00/s/Njg4WDEwMjQ=/z/locAAOSwd0BV48Dr/$_57.JPG
[00:45:35] <Contract_Pilot> Wonder what they db 25 is for the spectralite
[00:46:16] <Wolf_> software dongle
[00:46:56] <Contract_Pilot> Wonder is it allows the LPT to work with the Spectraligh Controller
[00:47:11] <Jymmm> FUCK DONGLES, period.
[00:47:16] <Contract_Pilot> I played for hours to try and get it to work on LPT no luck
[00:47:29] <Wolf_> probably for the cam soft guessing by the name
[00:47:39] <Contract_Pilot> http://www.ebay.com/itm/USED-LIGHT-MACHINES-CNC-LATHE-SPECTRALIGHT-TURNING-CENTER-MACHINE-/331656300520?hash=item4d384187e8
[00:48:08] <XXCoder> thats interesting machinbe
[00:48:45] <XXCoder> http://www.ebay.com/itm/Big-High-Power-Mini-Metal-Lathe-Soft-Metalworking-Woodworking-DIY-Model-Making/252061878808?_trksid=p2047675.c100009.m1982&_trkparms=aid%3D777000%26algo%3DABA.MBE%26ao%3D1%26asc%3D20131227121020%26meid%3Dcfd1aac42ec14e0a83bf0cbf05010772%26pid%3D100009%26rk%3D1%26rkt%3D1%26sd%3D331656300520
[00:48:47] <XXCoder> not bad
[00:49:50] <XXCoder> not too bad http://www.ebay.com/itm/Metal-Mini-Turning-Lathe-Machine-Motorized-Metalworking-DIY-Wood-Tool-Universal/261425835602 enough for tiny jobs lol
[00:51:23] <Contract_Pilot> I have the pair and the original controller but was un sucessfull at getting motor movement
[00:51:33] <Contract_Pilot> Was able to get them to enable.
[00:52:56] <Contract_Pilot> Some peole have had sucess making it work but will not release entire wiring.
[00:54:16] <Contract_Pilot> I listed the controller on ebay just because i done tripped over it 2 times now. http://www.ebay.com/itm/181885662393
[00:56:15] <XXCoder> wow http://www.ebay.com/itm/US-Ship-4-1-Planetary-Gearbox-Nema-23-Stepper-Motor-DIY-CNC-Mill-Lathe-Router-/331603050674?hash=item4d351500b2
[00:56:26] <XXCoder> 4.25 ratio
[00:56:54] <XXCoder> backlash sucks though at less than 1.5degree
[00:57:23] <Contract_Pilot> http://www.stevenrhine.com/wp-content/uploads/2015/09/Lightmachines-Lathe-Mill-.jpg
[00:58:09] <XXCoder> working on it to make it work
[00:58:11] <XXCoder> or selling?
[01:01:04] <Contract_Pilot> I will prob just make my own controller
[01:01:30] <Contract_Pilot> I have a bunch of Drivers and already replaced the steppers on the mill.
[01:01:48] <XXCoder> nice
[01:02:07] <Contract_Pilot> the controller unless i can find the info to make it work from LPT it stays on E-bay.
[01:02:35] <Contract_Pilot> http://www.stevenrhine.com/wp-content/uploads/2014/11/DM8010-Drivers.jpg
[01:02:49] <Contract_Pilot> 24-80V 10A Drivers
[01:03:12] <Contract_Pilot> Have 9 of them total and 2 are in use on my 12X36 lathe
[01:03:25] <Contract_Pilot> 3 will be used for MY G0704 Mill.
[01:03:49] <Contract_Pilot> Possibly 4 for the G0704 as i may add a 4th axis
[01:06:10] <XXCoder> cool :)
[01:06:22] <XXCoder> one of fun stuff I plan to play with is adding 4th axis
[01:06:38] <XXCoder> but basic way - direct connect to nema23
[01:06:54] <XXCoder> just turn around and stuff while parts being cut
[01:18:02] <Wolf_> well thats funny...
[01:18:38] <Wolf_> http://littlemachineshop.com/products/product_view.php?ProductID=1944&category=-269978449 costs less then just the housing + spindle ...
[01:26:45] <Contract_Pilot> Yep. some times
[01:31:10] <archivist> a mere 13lb
[01:40:22] <Contract_Pilot> Did find this page not sure if i want to make the board. http://projects.omahamakergroup.org/index.php?title=MakeryMill
[01:44:27] <archivist> er what, that page mentions grbl, a downgrade!
[01:46:37] <archivist> I would just just use something like http://www.ebay.co.uk/itm/390836898186 to update and use the normal parallel port
[01:47:57] <Contract_Pilot> That is what i was thinking...
[01:48:16] <Contract_Pilot> I have the Power supply 80V 5A and the Drivers
[01:49:01] <Contract_Pilot> Wonder if the PMW on that baord works
[01:49:17] <archivist> that particular variation seems to work well with random drivers unlike some BOBs out there
[01:50:36] <archivist> it works on mine, I added some isolation to it
[01:52:36] <archivist> I added an isolated 12 power supply so the pwm to the VFD would be ok
[01:53:10] <Contract_Pilot> http://www.ebay.com/itm/251307135179
[01:53:23] <Contract_Pilot> Not sure if it would work to make somthing compact.
[01:54:20] <Contract_Pilot> that way i dont have to give up my valuble drivers for these small machines
[01:55:48] <archivist> I love how the wiring diagram misses out the spindle
[01:57:15] <Contract_Pilot> I wonder if they actually use Nichicon VZ caps prob the generic JWCO
[01:57:57] <archivist> some TB series chips die easily, not as robust
[01:58:07] <Contract_Pilot> small steppers
[01:58:20] <Contract_Pilot> Small machines
[01:59:03] <Contract_Pilot> I could prob stuff a PS and a Board in each of the machine cases
[01:59:07] <archivist> its idiots disconnecting motors while switched on that is a common chip killer
[02:00:27] <Contract_Pilot> Amazon had them on for 29.99 the other day should have got one and tried it.
[02:09:27] <Contract_Pilot> or Could try this.. http://cnc4pc.com/product_info.php/c26-output-buffer-board-p-203
[02:09:54] <Contract_Pilot> Right now do not want to invest a lot in to the little machines weather is to nice.
[02:11:27] <Deejay> moin
[02:11:37] <Contract_Pilot> hey DeeJay
[02:11:45] <Deejay> hi there
[02:12:17] <Contract_Pilot> Still debating if i should play more with the spectralight controller
[02:27:02] <archivist> Contract_Pilot, some of the bobs do not drive the optos correctly
[02:27:43] <Contract_Pilot> Yea, what i am reading on the spectralight is LPT must be rock solid 5V
[02:28:08] <Contract_Pilot> They have a diagram for a buffer but if they are 20.00 why not
[02:28:16] <archivist> the one I pointed at has buffer chips
[02:28:36] <Contract_Pilot> Some one said to add 5V to the Opto and then set them active low
[02:29:10] <Contract_Pilot> But never produced a schem or diagram
[02:29:34] <archivist> some of my drivers are high ans some low, that driver works with both on my 5 axis
[02:30:11] <Contract_Pilot> not like i could not figure it out but i do not want to spend the time. http://www.stevenrhine.com/wp-content/uploads/2015/07/Ham-And-PCB-Rework-Bench.jpg
[02:30:40] <Contract_Pilot> Not working with a standard bob here.
[02:31:22] <archivist> I used to throw a ULN200x or some TTL on veroboard at the job
[02:32:08] <archivist> upper left hiding http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_02_03_cnc/P2030019.JPG
[02:32:13] <Contract_Pilot> to boost the parallel port drive current up enough to drive the controller
[02:32:56] <Contract_Pilot> http://projects.omahamakergroup.org/index.php?title=MakeryMill#J1_.27Computer.27_DB-25_Pinout
[02:33:11] <archivist> that bodge has since been replaced with that cheap BOB
[02:35:36] <Contract_Pilot> http://www.cnczone.com/forums/benchtop-machines/112153-engineering-software.html
[03:06:28] <MacGalempsy> Contract_Pilot what kind of machine are you converting
[03:07:12] <Contract_Pilot> I have 4 right now
[03:07:26] <MacGalempsy> any of them done?
[03:07:41] <Contract_Pilot> 12X36 Lathe G0704 Mill and the 2 small Sherlines
[03:07:59] <Contract_Pilot> the 12X36 is up on mach3 but moving to LCNC
[03:08:08] <MacGalempsy> cool
[03:08:25] <Contract_Pilot> Collecting parts for the G0704
[03:08:59] <Contract_Pilot> The table top machines just need to make a controller http://www.stevenrhine.com/wp-content/uploads/2015/09/Lightmachines-Lathe-Mill-.jpg
[03:09:57] <Contract_Pilot> http://www.stevenrhine.com/?p=1181
[03:10:29] <MacGalempsy> nice we have one of those mills in our CNC class. I have the biggest brother of it
[03:20:23] <trentster> anyone know why UI still says "home all" even tho I have homing stuff commented out for Z axis in ini file
[03:20:23] <trentster> I have prox sensors on X and Y with sequence Y=0 then X=1 but UI still is waiting for Z to autohome?
[03:25:41] <trentster> This is what my current ini file looks like yet it still wants to home all - https://gist.github.com/trentster/8546af7059bb92677b58
[03:25:55] <trentster> Any ideas or you think I have found a bug?
[03:26:01] <XXCoder> trentster: someone said something about Z being in file or something
[03:26:14] <XXCoder> think it was archivist
[03:26:32] <trentster> yeah but its commented out if you look at the gist
[03:27:23] <XXCoder> in other fie
[03:27:24] <XXCoder> file
[03:28:00] <trentster> which other file the "hal" file?
[03:28:21] <XXCoder> no idea
[03:40:23] <archivist> http://linuxcnc.org/docs/html/config/ini_homing.html
[03:44:10] <trentster> archivist: i have read that page it does not answer my question - or i missinterpreted something
[03:44:32] <trentster> archivist did you look at my config file?
[03:45:14] <MacGalempsy> dang, I got this talk on the 4th or 5th and just now getting the ppt together....
[03:46:16] <archivist> trentster, yes, the doc says set the sequence to -1 or nothing so try the other
[03:47:24] <trentster> archivist: so even if all homing for an axis is commented out - I still ned to set a sequence - thats a bit odd
[03:47:50] <archivist> I dont know, experiment
[03:48:51] <trentster> yup will do when I am in fron of the machine - thanks for the tip
[03:50:06] <fenn> MacGalempsy: industry standard practice is make the ppt the night before in the hotel room
[03:50:55] <MacGalempsy> heheh,
[03:51:09] <fenn> powerpoint is terrible anyway and should be banned - it caused the columbia disaster after all
[03:51:37] <MacGalempsy> there is some analysis involved. I got all the data from the oil and gas commission, but the surveys have to be entered by hand before I can analyze
[03:52:18] <fenn> are you an underwater welder or something?
[03:55:14] <MacGalempsy> no, geologist
[03:55:30] <MacGalempsy> i do modelling along the lateral of a horizontal well
[03:55:50] <MacGalempsy> so the talk is supposed to be about caviates of interpretation
[03:56:02] <MacGalempsy> using examples....
[04:58:53] <Contract_Pilot> I want to play so i orderd one of them Upgraded 5 Axis CNC Breakout Board
[05:00:09] <XXCoder> nice
[05:01:10] <Contract_Pilot> Hope it acutally ships form USA
[05:01:21] <Contract_Pilot> was about 10.00 others from china 6.00
[05:03:33] <Contract_Pilot> I will cobble somthing togather and handy to have is i want to play with somthing
[05:17:47] <archivist> another two users also have used that BOB and been happy
[05:18:11] <archivist> or three
[05:35:10] <Contract_Pilot> I have this little 5v 6A supply put that use use.
[05:36:18] <Contract_Pilot> Caps popped on it replaced them and it was way more stable
[05:37:47] <Contract_Pilot> 2200 16V replaced with low esr 2200 25V
[06:01:34] <Contract_Pilot> MIC2954-03BS
[06:03:08] <Contract_Pilot> uhhh running low about 140 left.
[06:03:22] <Contract_Pilot> Need a new reel.
[06:07:16] <Contract_Pilot> http://airplanemanuals.com/PCB/DM8010/Microkinetics%20DM8010%20Driver%20Repair%20Parts%20Small.jpg
[06:09:24] <Tom_itx> what's that?
[06:13:14] <Jymmm> Tom_itx: http://www.microkinetics.com/index.php?page=motor_drivers/dm8010
[06:15:57] <Jymmm> $298 for a single axis stepper driver?! YEOW
[06:16:18] <Sync> why not
[06:17:26] <Jymmm> Sync: Insert YOUR credit card here --> [ ]
[06:29:18] <Contract_Pilot> Yea, i have 9 of them
[06:29:39] <Contract_Pilot> and have fixed about 20 of them for others.
[06:31:05] <Contract_Pilot> they charge 150-175 to repair them hahaha... I list on e-bay and fic for 75.00
[06:33:58] <Contract_Pilot> Pop the s4010ls2 and it takes out the TL783C Regulator and some times the MIC2954-03BS... The fets generally fail in pairs IRF540 and IRF9540 that generally gives a fault.
[06:34:54] <Contract_Pilot> Current and Idle Current Resistor is a Must and is operating at 5A+ Heatsink and Forced Cooling a Must
[06:40:22] <Tom_itx> those seem rather HUGE
[06:43:03] <Contract_Pilot> http://www.applied-motion.com/products/stepper-drives/7080
[06:45:33] <Contract_Pilot> s4008ls2 SCR on them i got to fix one.
[06:45:39] <Jymmm> http://www.geckodrive.com/geckodrive-step-motor-drives/g213v.html
[06:46:58] <Contract_Pilot> 10A on the DM8010's
[06:47:25] <Contract_Pilot> I myself would not want to push then to 10A
[06:48:06] <Jymmm> Says 7A http://www.applied-motion.com/products/stepper-drives/7080
[06:48:08] <Contract_Pilot> I do need to go to the junk store and find some heat sinks
[06:48:46] <Contract_Pilot> Yea, the 9 I have are 10A http://www.microkinetics.com/index.php?page=motor_drivers/dm8010
[06:49:54] <Contract_Pilot> 2 are in use on my 1236 lathe
[06:52:42] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/cnc/psu/heatsink_bulk.jpg
[06:52:51] <Tom_itx> Contract_Pilot, slice off a piece of that
[06:53:18] <Jymmm> Tom_itx: You call that a heatsink?! Eeeeesh
[06:53:51] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/cnc/psu/driver_wiring.jpg
[06:55:06] <Contract_Pilot> Love to find a chunk of that
[06:55:19] <Tom_itx> scrap yard for alum price
[06:55:38] <Jymmm> Tom_itx: (Ok, the joke don't work when you cna't find the pic of the 5" tall heatsink I used to have)
[06:55:39] <Contract_Pilot> I go to junk store and find a Stereo Receiver with massive heatsink = good and costs 1-2.00
[06:56:07] <Tom_itx> Jymmm, that was ~6-8" x 6'
[06:56:22] <Contract_Pilot> 6' dam
[06:56:48] <Jymmm> Tom_itx: TALL, not wide. And this was cutoff from a 4ft piece
[06:56:58] <Jymmm> it was 6" wide as well
[06:57:18] <Contract_Pilot> You using ms or tefzel wire?
[06:57:59] <Tom_itx> also surplus aircraft wire
[06:58:02] <Tom_itx> not sure
[06:58:08] <Contract_Pilot> Yep aircraft wire
[06:58:21] <Contract_Pilot> White teflon wire
[06:58:49] <Contract_Pilot> I may have my avionics shop pull a few chunks thru the labler
[06:59:40] <Tom_itx> nice fine strand plated wire
[06:59:47] <Contract_Pilot> Yep.
[07:00:04] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/cnc/psu/wire.jpg
[07:00:05] <Contract_Pilot> Use it all the time in my HF aircraft installs
[07:15:03] <MacGalempsy> well guys my shift is over... got some done on the presentation, but also realized I need one or two more examples!
[07:15:13] <MacGalempsy> have good days
[08:07:41] <ganzuul> Aluminium is cheap! \o/
[08:19:41] <fenn> you're at the source
[08:21:20] <ganzuul> ?
[08:22:20] <fenn> nevermind i thought aluminum was smelted in finland
[08:22:55] <ganzuul> oh
[08:23:27] <ganzuul> We have the Free World's (TM) only chromium mine.
[08:25:51] <fenn> https://en.wikipedia.org/wiki/List_of_countries_by_aluminium_production
[08:27:13] <ganzuul> France is shining in its absence.
[08:27:51] <fenn> le creuset kicked them all out
[08:28:07] <ganzuul> wassat?
[08:28:14] <fenn> a cast iron cookware company
[08:28:36] <fenn> just kidding, i have no idea why france isn't making aluminum
[08:29:22] <norias> maybe due to energy requirements
[08:30:32] <ganzuul> France has a lot of nuclear energy and low electricity prices.
[08:32:47] <fenn> local scrap yard wants $2.75/lb for aluminum bars, which while better than buying new, seems like a lot to me, considering i've bought it in the past at $1/lb
[08:35:39] <fenn> 5.4 EUR/kg vs 2 EUR/kg
[08:36:19] <fenn> i guess it's possible the market price has gone up that much since 2008
[08:43:37] <ganzuul> I don't think I paid more than 3e/kg for the alu.
[08:44:34] <fenn> "... the age of electricity and of copper will be short. At the intense rate of production that must come, the copper supply of the world will last hardly a score of years. ... Our civilization based on electrical power will dwindle and die."
[08:44:51] <fenn> - noted geologist and copper-mining expert Ira Joralemon, 1924
[08:45:35] <cradek> be aware: from that, we can conclude that our supply of oil is infinite
[08:45:51] <cradek> because haha experts!
[08:45:52] <cradek> :-)
[08:45:57] <skunkworks> well - we havent run out yet! ;)
[08:46:15] <fenn> sure we can just make more using nuclear reactors
[08:48:38] <fenn> i wonder how many deep sea ecologies will get hoovered up in the upcoming sea floor mining rush
[08:50:17] <skunkworks> http://www.npr.org/sections/thetwo-way/2015/09/28/444115947/shell-oil-abandons-controversial-drilling-off-alaska-s-shore
[08:55:47] <skunkworks> that's pretty cool
[08:55:48] <skunkworks> https://www.youtube.com/watch?v=WizzhG2JrjQ
[09:32:42] <ganzuul> fenn: The law of the sea is the oldest international law there is, dating from, like, the 17th century. Might take another 100 years before the regulatory inertia is overcome for deep sea mining.
[09:33:38] <ganzuul> Hopefully we'll learn a lot more about the abyssal plains in the process though.
[09:34:45] <ganzuul> Also maybe get other commercial interests to interfere with overfishing.
[09:35:34] <ganzuul> Like getting an alternative source of revenue for small fisheries who are basically just pirates.
[09:37:36] <ganzuul> A submersible robot like the one SV seeker is building could be useful for that.
[09:39:27] <MattyMatt> something bigger and autonomous would be more handy
[09:39:47] <ganzuul> Might end up being a gold rush.
[09:40:01] <MattyMatt> there must be some good deposits in valleys
[09:40:14] <ganzuul> Maybe...
[09:40:35] <MattyMatt> so you need something that can go and taste the mud
[09:41:24] <ganzuul> They'r just sitting on the sea floor. Like bog iron.
[09:43:42] <ganzuul> Germany has an accessible claim of abour 230 million tons
[09:44:21] <MattyMatt> a soda can is ~15g. I've got a kg or two

[09:47:37] <ganzuul> o/
[09:49:02] <MattyMatt> cheaper copper will be nice
[09:49:51] <MattyMatt> I've ordered a qctp from china. suspiciously cheap
[09:50:23] <MattyMatt> http://www.ebay.co.uk/itm/Mini-Quick-Change-Tool-Post-Holder-Kit-Set-for-7-x10-12-14-Lathe-Tool-Holder/381406105635
[09:52:54] <fenn> what's with the sandblasting
[09:54:12] <ganzuul> MattyMatt: Looks like an appropriate price for a piston-type if you ask me...
[09:54:14] <MattyMatt> low rent beburring?
[09:58:19] <MattyMatt> the same toolholders will work if I make a tapered dovetail post in the future. This set will get me started
[09:59:20] <MattyMatt> I just gotta make a custom bolt with a whitworth thread, and a handle on top
[10:01:16] <Contract_Pilot> 2000 steps/rev used with a 5 pitch lead screw, you get .0001
[10:01:16] <Contract_Pilot> inches/step right?
[10:02:57] <ssi> yeah
[10:02:59] <archivist> easy too work backwards .2 "=2000 counts, .1 is 1000 so near enough
[10:04:51] <archivist> but be aware if you are using microsteps they wont all be exactly that size
[10:05:44] <archivist> some light reading http://www.micromo.com/microstepping-myths-and-realities
[10:07:42] <ssi> yeah never assume that microstepping is going to give you increased precision
[10:08:07] <archivist> I was using 8 microsteps when testing the hobbing setup, the error was easily visible
[10:08:23] <archivist> and very audible
[10:08:57] <Contract_Pilot> Ok, booked marked for reading
[10:09:27] <archivist> Contract_Pilot, please replicate this when you try it :) http://www.archivist.info/cnc/screw_error/
[10:09:40] <ssi> I got some work done on the pitts this weekend
[10:09:41] <ssi> https://scontent-atl3-1.xx.fbcdn.net/hphotos-xpf1/v/t1.0-9/12043024_10100786356532712_3563634788597680477_n.jpg?oh=524381c5fd8756fff50a65ad2ebfe70e&oe=56A97CD0
[10:10:05] <archivist> what! not working on the filing machine :)
[10:10:09] <ssi> no :/
[10:10:29] <archivist> I was dragging the CMM undercover
[10:10:29] <Contract_Pilot> Cool
[10:10:50] <ssi> dig into it at all?
[10:11:21] <archivist> I got the air connected yesterday and pushed the axes around a bit
[10:11:48] <ganzuul> Aluminium is gummy...
[10:12:09] <fenn> wrong kind of aluminum
[10:12:09] <pcw_home> MacGalempsy: you can use any output signal you want to enable the spindle but in any case,
[10:12:11] <pcw_home> spindle-ena must also be set true when you want the spindle on ( since it enables analog output 5 )
[10:12:15] <archivist> going to shove the servo box under the cmm as the rack takes too much space
[10:12:36] <ganzuul> fenn: It has been machined. Old belt pullies.
[10:13:31] <archivist> ganzuul, lubrication when cutting for that sort of al
[10:14:13] <ganzuul> archivist: Is my normal cuttin'ol good?
[10:14:33] <ganzuul> The off-brand WD-40 type smells weird...
[10:14:35] <ssi> aluminum likes different lubricants
[10:16:30] <ganzuul> Should I get some WD-40?
[10:16:54] <fenn> ganzuul what is your surface speed?
[10:17:08] <ganzuul> Slooow
[10:17:17] <fenn> go faster
[10:17:42] <ganzuul> It has these ribs I'm trying to take off. Makes the machine vibrate.
[10:18:09] <ganzuul> I just added a big chipbreaker, so I have more positive rake.
[10:18:18] <ganzuul> So I suppose higher speeds make sense now...
[10:18:31] <ssi> aluminum cuts better with negative rake
[10:18:32] <ganzuul> And alu chips are sharp!
[10:18:59] <ganzuul> Oh...
[10:19:15] <ganzuul> I thought aluminium did not need to be heated up a lot to be cut.
[10:19:37] <ganzuul> So you shear it off rather than rub it off.
[10:19:43] <ssi> I might have my terminology upside down
[10:19:55] <ssi> aluminum cuts better with a more acute angle
[10:20:07] <fenn> that's positive rake
[10:20:26] <ssi> k
[10:20:45] <ganzuul> \o/
[10:20:51] * ganzuul 's logic works!
[10:21:17] <ssi> also a chipbreaker doesn't increase the rake angle unless it goes right up to the edge
[10:21:58] <ganzuul> It does...
[10:26:12] <ganzuul> http://imgur.com/p4k9m8Y
[10:26:18] <ganzuul> Thusly.
[10:26:37] <ssi> k
[10:27:21] <ssi> well... run the spindle as fast as you can, use WD40 or IPA as lube, and hope for the best
[10:27:24] <ssi> some alloys cut like shit
[10:27:42] <ganzuul> :o
[10:27:51] <ganzuul> Okay. Goan get some WD40.
[10:28:14] <ssi> get some IPA too, I've heard it works really well
[10:28:16] <ssi> never tried it myself
[10:30:36] <ganzuul> Eh, a bit of a way off, to get IPA...
[10:31:13] <ganzuul> But I do need some of that stuff anyway.
[10:49:37] <MrSunshine> hmm, tried melting some more cast iron .. with new nozle on the burner, melted alot faster but poured it to cool :/ Started to see sparks comming out the top of the furnace so thought that was the que .. but i was wrong there? =)
[10:50:12] <ssi> MrSunshine: have any pictures of your furnace?
[10:50:14] <ssi> I'm about to start building one
[10:50:25] <ssi> actually have my cousin out hunting for refractory ingredients today
[11:08:36] <MattyMatt> there was a pretty indoor one on ebay that plumbs into mains gas. nice design to rip off maybe? http://www.ebay.co.uk/itm/HME-Crucible-Furnace-AMF-T12-230V-Automatic-Melting-Tilting-Furnace-/291563204177
[11:09:04] <ssi> whoa neat
[11:10:51] <MattyMatt> £330 seems a lot, but it might not be the most expensive appliance in the kitchen
[11:11:34] <MattyMatt> tell the wife it's a soupmaker and you steal her workspace. paint yours white :)
[11:11:45] <ssi> no wife, and no mains gas :)
[11:12:12] <MattyMatt> ah well, same setup would work on propane
[11:12:52] <ssi> I have some five gal steel drums, I'm gonna make some small furnaces to play around before I make my final one
[11:12:54] <MattyMatt> no wife does diminish the returns of making it pretty I guess
[11:13:41] <MattyMatt> me too. 1x 5 gallon first will be plain cement mixed with rockwool
[11:14:32] <ssi> my cousin found a place that has refractory
[11:14:37] <MattyMatt> if that goes well I'll buy a sack of the expensive castable refractory
[11:14:38] <ssi> he's gonna get me 110lb of econocast 30
[11:14:48] <ssi> plus 100lb of fireclay and 100lb of perlite to make some diy stuff
[11:14:57] <ssi> and some ceramic blanket if they have an open box to sell partials
[11:15:04] <ssi> 50 sqft box is $65; I don't need that much
[11:15:31] <ssi> I have four 5 gal drums to play with
[11:15:34] <MattyMatt> I've heard mixed opinions about perlite in the mix
[11:15:41] <ssi> and two 55 gal drums, but I think those are going to be WAY too big
[11:15:49] <ssi> I'd like to find a 30 gal drum
[11:16:07] <MattyMatt> cut one in half, or is it still too fat?
[11:16:15] <ssi> yeah it's the diameter that kills me
[11:16:21] <ssi> it's 24" diameter
[11:16:41] <ssi> put another way: a 5 gal drum is 0.68 cuft
[11:16:46] <ssi> a 55 gal drum is 7.4 cuft
[11:16:47] <Jymmm> fire bricks are CHEAP
[11:16:59] <ssi> the castable refractory is $65/bag, and a bag is 0.3 cuft
[11:17:01] <ssi> shit is dense
[11:17:24] <ssi> damn cubic functions and their making everything expensive :)
[11:17:53] <MattyMatt> yeah a square furnace made of bricks, all held together with handy angle. that was a neat design too
[11:18:28] <ssi> I figure I'll mix up some diy stuff for the first furnace
[11:18:31] <ssi> I expect it to get trashed
[11:18:45] <ssi> and then once I have some experience, I'll mix some commercial castable for a small furnace
[11:18:51] <ssi> and then later I'll try to build a bigger one
[11:19:27] <Jymmm> MattyMatt: sqaure bricks in a hex/octogon pattern
[11:19:29] <ssi> I'd like to eventually make a waste oil burner
[11:19:39] <ssi> we generate tons of waste oil
[11:19:54] <Jymmm> ssi: use it to fire your furnace
[11:19:57] <ssi> that's the point
[11:20:17] <ssi> I think we have about 130 gallons of waste oil on hand right now
[11:20:43] <ssi> I'll start with propane because it's far easier
[11:21:06] <fenn> i once fired a furnace with stale donuts
[11:21:28] <ssi> they are quite caloric :P
[11:21:47] <MattyMatt> http://www.backyardmetalcasting.com/guest_martin.html
[11:22:01] <ssi> nice
[11:22:14] <ssi> shit where was that really nice scratchbuilt one
[11:22:15] <ssi> lemme find it
[11:22:48] <ssi> model engine guy in the UK
[11:22:52] <ssi> what was his name
[11:23:00] <MattyMatt> myfordboy?
[11:23:29] <ssi> might have been but I don't think so?
[11:23:55] <fenn> myfordboy's oil fired furnace http://youtu.be/HJ9YoRMoO5Y
[11:23:57] <ssi> yeah maybe it was
[11:24:12] <MattyMatt> https://www.youtube.com/watch?v=ZbnroanPt4g&list=PLQyl_LP87ZqK5nzJTgDKWWkZsP2z0pfeZ
[11:24:19] <MattyMatt> playlist
[11:24:22] <MattyMatt> :)
[11:24:32] <ssi> yes that's the one
[11:24:40] <ssi> he did a nice job on it
[11:24:50] <ssi> and he's not limited to the barrels he can get his hands on
[11:24:55] <ssi> although rolling all that steel doesn't sound like fun
[11:24:56] <MrSunshine> ssi: hmm ...
[11:25:36] <MrSunshine> i built it with fireproof stones and fire mortar and then mixed perlite with fire mortar for the insulating layer outside .. (can mix with sodium silicate also as binder)
[11:26:16] <ssi> MrSunshine: I have a small tub of fire mortar, I was thinking about for my first one making it with DIY refractory (fireclay, perlite, sand, cement), and hotfacing it with the mortar
[11:27:24] <MrSunshine> ssi: https://photos.google.com/album/AF1QipPjEoVXBSdQi4AIks8ZPKLKN0zucjrh8lEdSDNx if you can view it, there are some of th epictures .. never finnished it fully so
[11:27:41] <ssi> 404. That’s an error.
[11:27:42] <MattyMatt> use packed earth, and remake it every time
[11:27:42] <ssi> The requested URL was not found on this server. That’s all we know.
[11:27:43] <ssi> lol
[11:28:22] <MrSunshine> https://goo.gl/photos/UajH9QAmuRXfwn2D8
[11:28:31] <ssi> that worked
[11:29:32] <MrSunshine> started cracking after i started trying to melt cast iron it it tho . .but nothing can get anywhere until it falls apart totaly =)
[11:29:42] <ssi> heh
[11:29:53] <ssi> I want to be able to eventually do iron but I'm content to stick with aluminum for a little bit
[11:30:02] <fenn> i always thought iron melting furnaces had to be huge tall chimney things, but that one's just a BBQ propane tank
[11:30:12] <MrSunshine> seems i got the heat atleast .. can melt mild steel in it if i stick a bar inside of it .. i just need to learn to be more patient =)
[11:30:21] <ssi> nah iron furnaces just have to get really effin hot without falling apart
[11:31:07] <MrSunshine> fenn: thats a reducer to produce iron from ore you are thinking of =)
[11:32:12] <MrSunshine> was so bright inside the furnace this time after the burner upgrade that i had to have welding googles on to look down there to see how it was doing
[11:32:32] <MrSunshine> melted huge chunks of cast iron in very short while when it had come up to temp =)
[11:32:48] <ssi> I have a teeny little heat treat furnace
[11:32:49] <ssi> https://pbs.twimg.com/media/B4Eb0kYIcAAzwJU.jpg:large
[11:32:58] <JT-Shop> anyone using a touch screen with 2.7 on Debian Wheezy?
[11:33:03] <ssi> electric
[11:34:13] <MrSunshine> hmm making my own transfer punches for holes that i cant poke throught .. i wonder how i should do that :/
[11:34:24] <ssi> huh?
[11:34:26] <MrSunshine> i could make just dowels that fit good down the holes and cut them to length i guess
[11:34:40] <CaptHindsight> JT-Shop: I tried using a panel with multitouch last year with 2.6 and Wheezy
[11:35:39] <MattyMatt> ssi that looks hot enough to melt alu
[11:35:48] <ssi> yeah it is
[11:35:52] <MrSunshine> http://www.victornet.com/productthumbs/622.jpg thats what i need realy
[11:35:54] <ssi> that little oven is 2500F I think
[11:36:01] <ssi> 2500C? I forget
[11:36:17] <MattyMatt> that'd do me, for turning soda cans into machinable stock
[11:36:26] <roycroft> 2500f would be pretty darn hot
[11:36:30] <roycroft> 2500c no way
[11:36:34] <ssi> 2500F
[11:36:42] <ssi> is the max temp on it I think
[11:36:49] <roycroft> ceramic kilns generally don't go that high
[11:36:58] <roycroft> porcelan fuses at around 2300f, iirc
[11:37:21] <fenn> MattyMatt: you don't want to use cans, they're not very machinable
[11:37:27] <roycroft> yeah, cone 10 is 2381f
[11:37:43] <ssi> I think I run steel up to around 2250F and hold it for 30-60m or so
[11:37:44] <MattyMatt> I'll bung in a few 3.5" hdd into the mix
[11:37:55] <roycroft> and most ceramic kilns don't go up to cone 10 - cone 6 (2269f) is commonly the upper limit
[11:38:10] <ssi> unfortunately that little furnace isn't really big enough or shaped appropriately to put a crucible of aluminum in
[11:38:30] <MrSunshine> just weld a square box for the alu ? =)
[11:38:32] <ssi> roycroft: I had a ceramic kiln taht I was GOING to use for this, but I sold it to some friends of mine
[11:38:42] <ssi> MrSunshine: the opening is only 3.5x4"
[11:38:49] <ssi> it's like 7" deep
[11:38:51] <MattyMatt> tip it on its back and fill it :)
[11:38:53] <fenn> also cans have a lot of oxide relative to metal
[11:38:55] <roycroft> i have a ceramic kiln that i used for heat treating a few times
[11:38:57] <ssi> if I turned it up on end it might work ok
[11:39:00] <roycroft> it is a top loader
[11:39:00] <ssi> but I dunno if that's a good idea
[11:39:14] <roycroft> but i ended up getting a front loader kiln for heat treating, and that works out a lot better for me
[11:40:00] <roycroft> if i were making a transfer punch, though, i would not soak the whole think in a furnace
[11:40:06] <roycroft> i would just harden the very tip with a torch
[11:40:33] <ssi> I'd probably rather harden the whole thing, but then draw it from the handle end
[11:40:45] <ssi> so the handle ends up softer
[11:40:46] <MattyMatt> you'd normally harden and quench, then temper everything but the tip
[11:40:58] <roycroft> the problem with that is that the piece would warp a bit in the furnace
[11:41:02] <ssi> draw it from the handle end until the tip is light straw or so
[11:41:18] <roycroft> and if you turn the punch to a tight tolerance you would have to grind it straight after heat treating
[11:41:19] <ssi> roycroft: spin grind it after
[11:42:12] <roycroft> that seems like a lot of work for a transfer punch
[11:42:16] <ssi> yep
[11:43:29] <MattyMatt> if you could get a set of gauge pins, all with a regular bore for a replacable punch, that'd be handy
[11:43:38] <ssi> that's a pretty good idea
[11:44:38] <MattyMatt> less exotic, take the transfer punch next size down, and wrap it in tape
[11:45:06] <Jymmm> fenn: I realy like is furnace "lid" setup
[11:45:11] <Jymmm> his^
[11:45:26] <Jymmm> fenn: what is the 15psi compressed air for?
[11:45:43] <fenn> turning the oil into a mist
[11:45:50] <roycroft> or make a bushing to hold the transfer punch
[11:46:20] <Jymmm> fenn: is the compressed air AFTER the plastic shutoff valve?
[11:46:41] <fenn> yes\
[11:46:53] <fenn> it's a venturi
[11:46:59] <Jymmm> fenn: Ok, I must have missed that.
[11:47:24] <Jymmm> fenn: Lots of hand made tools, he's been doing this for a while =)
[11:47:32] <skunkworks> fenn, http://electronicsam.com/images/KandT/cncworkshop/fennalum.JPG
[11:48:47] <Wolf_> nice… bought a air cylinder on eBay the other night, seller just messaged me that they are refunding me half the cost because it has some surface scratches on it :D
[11:50:02] <Jymmm> pressure gauge on propane tank? I don't see a regulator either
[11:50:52] <Jymmm> Wolf_: who's the seller?
[11:50:58] <CaptHindsight> how many beards does DIY blast furnace require? https://www.youtube.com/watch?v=8Q9LMMLfAag
[11:51:37] <ssi> lololol
[11:51:59] <Wolf_> http://www.ebay.com/usr/excess-tech?_trksid=p2060353.m2749.l2754
[11:52:58] <JT-Shop> CaptHindsight, how did that work out?
[11:53:02] <Wolf_> for this thing http://www.ebay.com/itm/191691397889
[11:55:43] <CaptHindsight> JT-Shop: not too well, even as a simple touch screen it was slow and clumsy, we added a keyboard to the system due to frustration with it
[11:56:52] <JT-Shop> thanks, what GUI did you try?
[11:56:58] <CaptHindsight> JT-Shop: the latest version of ubuntu with gnome3 had system tweaks to support multitouch but we didn't want to use gnome3 or deal with building kernels for ubuntu
[11:57:39] <CaptHindsight> JT-Shop: gnome3 and lxde
[11:57:59] <CaptHindsight> last year multitouch support in Linux was just poor
[11:58:28] <CaptHindsight> the Ubuntu devs had done all sorts of tweaks to sort of make it usable
[11:58:36] <CaptHindsight> haven't tried again yet
[12:00:01] <Jymmm> Wolf_: thanks
[12:00:15] <JT-Shop> is multitouch a special touch screen?
[12:00:53] <Jymmm> CaptHindsight: is that gold extraction?
[12:01:39] <CaptHindsight> JT-Shop: they have the added features (if the drivers support it) of having multi finger gestures like an android phone
[12:01:42] <fenn> "black magnetic sand" sounds like iron
[12:01:45] <ssi> he's putting a lot of work into extracting metals
[12:01:51] <ssi> I wonder what sort of recovery he's getting
[12:02:16] <fenn> it's performance art
[12:02:24] <ssi> lol
[12:02:26] <CaptHindsight> all I remember is 3 beards, was there a furnace in that video as well?
[12:03:58] <fenn> some people play minecraft, others build a compound in the desert
[12:04:06] <fenn> whatever floats yer boat
[12:04:10] <ssi> I'm more of the latter type ;)
[12:04:13] <CaptHindsight> JT-Shop: http://www.newegg.com/Product/Product.aspx?Item=12K-0077-000R2&cm_re=multitouch_panel_acer-_-12K-0077-000R2-_-Product or similar
[12:07:07] <JT-Shop> ok I was wondering about regular touch screens, I use ELO's on ubuntu
[12:07:27] <ganzuul> *cough*
[12:07:31] <ganzuul> yup, it's IPA
[12:07:44] <ganzuul> Wow, I got lucky.
[12:08:24] <ganzuul> Got it even cheaper, from this bottom-of-the-barrel store which was just about to close. The previous manufacturer (Neste) stopped production.
[12:08:39] <ganzuul> Got 2 liters!
[12:09:36] <CaptHindsight> JT-Shop: haven't tried, let us know if you do. I tend to have problems with debian and anything besides 1-2 standard displays
[12:09:51] <ganzuul> Should I mix the WD40 with the IPA, or...?
[12:10:14] <CaptHindsight> most IPA's are bad beers anyway
[12:10:33] <ganzuul> Isopropanol alcohol. :p
[12:11:06] <CaptHindsight> ganzuul: might depend on the type of IPA you use
[12:11:10] <ganzuul> I'm manly, but I'm not WD40 with beer manly.
[12:11:22] <CaptHindsight> 95%, 70%, 50% in water
[12:11:34] <CaptHindsight> the vapor pressure will vary greatly
[12:12:02] <CaptHindsight> so the ~95% stuff is going to evaporate pretty quickly
[12:12:18] <ganzuul> hmm
[12:12:47] <roycroft> the -anol suffix means "alcohol"
[12:12:48] <JT-Shop> yea debian is somewhat a pain, I do have an ELO that I can plug in and test
[12:13:05] <roycroft> saying isopropanol alcohol is essentially saying isopropyl alcohol alcohol
[12:13:15] <roycroft> i.e. the "alcohol" is redundant
[12:13:16] * ganzuul looks up the MSDS
[12:13:21] <Jymmm> Ah, it IS gold extraction... https://www.youtube.com/watch?v=5Um6Z6X9_v8
[12:13:41] <ssi> yea
[12:13:41] <Jymmm> ...and this https://www.youtube.com/watch?v=e_AjDqp9-hA
[12:14:58] <ganzuul> I think it's 95%...
[12:16:22] <CaptHindsight> ganzuul: you can add water yourself to cut it
[12:16:23] <ssi> it never ceases to amaze me how the desert is always full of just bullshit debris and detritus everywhere
[12:16:28] <CaptHindsight> if you need to
[12:16:41] <Jymmm> Well, there are suppose to be diamond and gold in the area, maybe I need to look into a claim
[12:16:48] <ssi> claims are cheap
[12:16:55] <ssi> my cousin's husband was trying to talk me into buying mining claims
[12:16:56] <Jymmm> ssi: Nah, that's brought in =)
[12:17:06] <lair82> pcw_home you around?
[12:17:11] <ssi> Jymmm: well yeah but everyone who lives there just leaves shit lying around everywhere
[12:17:14] <Jymmm> Yeah, it's WORKING the claim that's a bitch =)
[12:17:43] <Jymmm> ssi: Eh, I dont think that guy was just dumping stuff,
[12:18:17] <Jymmm> it's the desert, not going to have nice garages and warehouses with shelving and such
[12:18:37] <ssi> even in residential areas though, there's old washingmachines and boats and rusted out cars and just crap everywhere
[12:18:42] <ganzuul> CaptHindsight: Should it be 50/50 for cutting aluminium?
[12:18:42] <ssi> in peoples' back yards
[12:19:01] <ssi> it'd never fly in greener areas of the country
[12:19:21] <ssi> you know how much I had to fight with the city becaues of a forklift parked in my driveway? :P
[12:20:53] <pcw_home> lair82: yes
[12:21:20] <lair82> Do you know what this might be referring to? http://pastebin.com/FJua4mbQ
[12:21:20] <ganzuul> ah, I'ma just try some mixture...
[12:21:59] <fenn> ganzuul: i think the idea is that it evaporates quickly and leaves a clean part
[12:22:13] <fenn> vs kerosene which doesn't evaporate
[12:22:39] <lair82> I'm fixing the lathe I have that had the faulty HDD, with a new SDD, and the latest Debian wheezy image, running 2.7.0
[12:24:18] <CaptHindsight> ganzuul: by adding water you can control how quickly it evaporates
[12:24:42] <ganzuul> Added just a little water
[12:24:44] <CaptHindsight> it's highly flammable so be aware
[12:24:58] <ganzuul> mmh
[12:25:07] <ganzuul> Using a small container.
[12:25:14] <ganzuul> 10ml maybe
[12:25:59] <pcw_home> lair82: whats your servo thread period?
[12:26:33] <lair82> pcw_home SERVO_PERIOD = 2000000
[12:26:39] <CaptHindsight> ssi: did you have to disguise it as a portable basketball hoop or something?
[12:26:52] <ssi> no I told them to eat a dick
[12:27:02] <ssi> they tried to cite me under abandoned vehicle ordinances
[12:27:10] <ssi> but it's neither a vehicle nor abandoned under their definitions
[12:27:16] <CaptHindsight> heh
[12:27:33] <ssi> and there's a guy in my neighborhood that has a freakin 10x10 5 ton parked in his driveway
[12:28:55] <lair82> pcw_home this was ubuntu 10.04 until about 2 hrs ago when I mounted the new ssd
[12:29:50] <pcw_home> what CPU?
[12:30:24] <pcw_home> those numbers indicate 292 usec of latency
[12:30:31] <Jymmm> Ah, you have to SMASH the glass to get the gold out after seperation from the black sand
[12:31:06] <ganzuul> Speaking of CPUs, I got one of those new bargain OrangePi, RasPi clones.
[12:31:10] <ssi> Jymmm: yea it's interesting seeing that done... I always wondered how it worked
[12:31:36] <Jymmm> ssi: Yeah, i knew that black sand was always a bitch
[12:31:41] <Wolf_> pcw_home: have you heard of anyone using a SPINx1 on a sewing machine servo motor controller?
[12:32:10] <lair82> Another AMD , a A-4 4020 I believe
[12:32:13] <pcw_home> SPINX1 is for spindles (not bidirectional)
[12:32:44] <Wolf_> pcw_home: yeah, I get that, drive motor, not positional
[12:32:55] <lair82> I see where this is going. Might as well go back to ubuntu on this one then...
[12:33:43] <Jymmm> ssi: It's funny/ironc how they use one mineral to extract/seperate another mineral =)
[12:34:20] <fenn> such irony
[12:34:24] <ssi> the flux you mean?
[12:34:33] <Jymmm> yeah
[12:34:51] <lair82> pcw_home, 82381 ns Max jitter on a 1ms thread
[12:35:11] <Wolf_> pcw_home: this kind of thing, uses a optical gradient sensor for the speed control http://www.ebay.com/itm/321878573933
[12:35:29] <CaptHindsight> fenn: no, I think it was Gold :p
[12:36:45] <lair82> This AMD/Asrock combo isn't worth tits on a boar hog in regards to running Debian wheezy
[12:36:51] <pcw_home> Yeah but when actually doing something you had 292 usec latency
[12:36:53] <pcw_home> ( the latency test is rather optimistic since it doesn't _do_ anything )
[12:38:03] <Jymmm> That "Chapman Flux" process is a trip, just smack off the glass and you have gold/silver ball. And it look like it came off easily too
[12:38:04] <ganzuul> It works! :D
[12:38:19] <pcw_home> you might try the AMD on Preemt-RT since its a newer kernel
[12:38:27] <ganzuul> Though how can I finish a part without getting wasted on the fumes?
[12:38:43] <Jymmm> ganzuul: Breath DEEPLY
[12:38:51] <ganzuul> :V
[12:38:56] <Jymmm> ganzuul: then you just won't care =)
[12:39:11] <ganzuul> I haven't had any booze for 2 weeks to afford this new addiction of mine.
[12:39:24] <lair82> pcw_home will that make any difference on my configs?
[12:39:27] <ssi> sweet my minion is getting me 110lb of econocast 30 and 100lb of 20 mesh fireclay
[12:39:29] <Jymmm> lol
[12:39:44] <pcw_home> shouldn't
[12:40:13] <pcw_home> no guarantees its any better though
[12:40:34] <Jymmm> Is a 70ft run of 12ga THHN "too long" for 220V@20A ?
[12:41:10] <Jymmm> (which will be two 110@20A eventually)
[12:41:13] <lair82> I don't know if it's worth it, it is almost an identical combo to what I have to replace on my mills, I was rolling the dice to see if this would work.
[12:41:30] <lair82> I'm just going to rebuild this on ubuntu
[12:41:38] <ssi> Jymmm: that's overloading it by about twice for power transmission as per code
[12:41:44] <ssi> ampacity table says 9.3A for transmission
[12:42:04] <Jymmm> ssi: which table you loking at?
[12:42:19] <ssi> first one googs threw at me :)
[12:42:19] <ssi> http://www.powerstream.com/Wire_Size.htm
[12:42:32] <Wolf_> pcw_home: no idea on that driver question?
[12:42:43] <ssi> 2% voltage drop
[12:44:52] <Jymmm> ssi: Where do you see 2%?
[12:45:00] <ssi> I ran your numbers through their calc at the bottom
[12:47:36] <CaptHindsight> Jymmm: 70ft run of 12ga THHN will be fine
[12:48:08] * ganzuul has made an aluminium rat's nest!
[12:48:18] <ssi> yeah aluminum strings like a bitch
[12:48:20] <ganzuul> Shiny on one side, dull on the other.
[12:48:23] <Jymmm> CaptHindsight: All these charts/calculators are jsut mucking with me, some say "yeah great", others say "oh no, you can't do that" lol
[12:48:31] <ssi> and those strings will slice the hell out of you if you try to pull it off with bare hands :P
[12:49:03] <CaptHindsight> Jymmm: you have to understand the electrical code to make use of the calculators
[12:49:20] <Jymmm> CaptHindsight: I got the breaker in dual pole bonded handles =)
[12:49:42] <ganzuul> ssi: I have dealt with torn beverage cans before...
[12:49:57] <ganzuul> Though I found these cut-proof gloves.
[12:50:14] <ganzuul> Puncture proof, to be exact.
[12:50:35] <ganzuul> Just didn't have my size... Cause I've got little babby hands.
[12:50:36] <Jymmm> CaptHindsight: I had been going off this http://www.cerrowire.com/ampacity-charts, but then was thinkinng 70ft is a long run too, so wasn't sure.
[12:50:52] <Wolf_> best to pull the stuff out with needle nose pliers while machining
[12:51:22] <Wolf_> makes a huge mess if it wraps around the work or chuck
[12:51:33] <Jymmm> ganzuul: Um, I've seen pucture proof and then cut proof, but not both in the same gloves
[12:51:50] <CaptHindsight> Jymmm: max continuous load should only be ~16A
[12:51:54] <ganzuul> At the high speed I ran at and with the apparently insuffiecient gear ratio I didn't have much time to worry about much but disengaging the power feed...
[12:52:10] <CaptHindsight> so you use 16A to factor your voltage drop not 20A
[12:52:28] <enleth> Jymmm: there's no escape from doing the math. The code tells you what thr absolute limit is, the tables are a ballpark hint for when you do the calculations mostly in memory
[12:53:11] <Jymmm> CaptHindsight: Where did you pull ~16A from?
[12:53:28] <ganzuul> Jymmm: ...cut proof. Must have seen puncture proof elsewhere in the same store. HPPE Tsunooga®
[12:53:58] <CaptHindsight> Jymmm: you can't have a continuous load over ~16A on a 20A breaker
[12:54:53] <Jymmm> CaptHindsight: It's mostly motor startup
[12:55:30] <CaptHindsight> Continuous Load. A load where the maximum current is expected to continue for 3 hours or more.
[12:55:56] <enleth> Jymmm: oh, and the voltage drop and the resultant heat that limits sustained loading is only a start. Then you need to account for short circuit loop resistance. It can't be too high or too low. And you measure/calculate it for the full route from the nearest transformer.
[12:58:35] <Jymmm> enleth: Well, beyond the smartassery... nearest xmfr is actually the underground service on the corner of the property =)
[12:59:15] <Jymmm> CaptHindsight: ty btw
[12:59:29] <enleth> Jymmm: that means you can't use oversized wire "just in case"
[13:00:06] <Jymmm> enleth: that's all beyond my paygrade
[13:00:32] <CaptHindsight> Jymmm: it's a confusing but branch circuits that have receptacles on them vs dedicated loads are handled differently
[13:01:03] <CaptHindsight> thats where the confusion might come in when looking at those calculators
[13:01:11] <enleth> Jymmm: if the combined resistance under a short circuit is too low, the short circuit current would be so high for a brief time that breaker contacts could weld together, or the voltage spike created upon opening of the contacts could be higher than the breaker can sustain.
[13:01:13] <Jymmm> CaptHindsight: Why? Resistance in the contacts?
[13:01:35] <enleth> Jymmm: thus, it would fail to disdipate the arc
[13:01:46] <enleth> *dissipate
[13:02:32] <enleth> There's few things worse than a sustained arc through a breaker that tried to open
[13:02:42] <CaptHindsight> Jymmm: wiring size and breaker depend on the type of load and conduit fill and the location it's installed
[13:03:46] <Jymmm> "conduit fill" ?
[13:04:16] <Wolf_> aka air space
[13:04:22] <Jymmm> ah
[13:04:26] <CaptHindsight> number of current carrying conductors in a single raceway
[13:04:32] <enleth> Jymmm: how much stuff is stuffed into the conduit
[13:04:47] <Jymmm> four 12ga thhn in 3/4" PVC
[13:05:01] <CaptHindsight> yeah we cover this last week
[13:05:05] <Jymmm> =)
[13:06:06] <CaptHindsight> Jymmm: the load is just one motor correct? Not a motor and some 120V receptacles.
[13:08:12] <Jymmm> CaptHindsight: It's actually ALL 120V receptacles The main loads are a dust collector, the laser, computer(s), tiny airbrush compressor,
[13:08:13] <CaptHindsight> the NEC might look a goofy at times but it's also based on what's burned down and what didn't over the past 100 years
[13:08:56] <Jymmm> CaptHindsight: Each are 110V and less than 10A (excluding startup)
[13:09:01] <CaptHindsight> Jymmm: then you need another panel on the other end of the 70ft run
[13:09:05] <Wolf_> imo Jymmm, you might be better off doing a sub panel from that 220 run
[13:09:22] <CaptHindsight> not just better off, it's required by code
[13:09:42] <Jymmm> I was actually planning on that.
[13:10:42] <Wolf_> pcw_home: no idea? if not no worries, I’ll just get one of them setups and scope it first
[13:11:01] <CaptHindsight> if he had two single pole breakers in the panel supplying the 2 120V branch circuits then he won't need a second panel
[13:11:59] <Wolf_> if its to a shop/outbuilding I would just put a 50A sub in and be done with it
[13:12:12] <CaptHindsight> but then he can't have a 240V load on those conductors as well
[13:12:30] <Wolf_> me personally I installed a 100A sub panel in my garage
[13:12:44] <CaptHindsight> I think he already had the #12 wires
[13:12:53] <Jymmm> This is the breaker I got http://www.ebay.com/itm/181872562658
[13:12:55] <CaptHindsight> and he's on a budget
[13:13:00] <Wolf_> but that was a 200 foot run...
[13:13:07] <Wolf_> so I had to go big
[13:13:24] <Jymmm> I have the 12# already Wolf_
[13:13:56] <Wolf_> still cheaper to do it right once then do it twice...
[13:14:21] <Jymmm> Wolf_: You're right.
[13:14:30] <CaptHindsight> now all he needs is a panel with main lugs and spaces for a few single or two pole breakers
[13:14:46] <Wolf_> small 4 breaker sub isn’t much
[13:15:52] <Jymmm> http://www.homedepot.com/p/Eaton-125-Amp-12-Space-24-Circuit-Type-BR-Main-Lug-Loadcenter-Value-Pack-Includes-5-Breakers-BR1224L125V1/100557051
[13:16:07] <FinboySlick> Connect it above the meter if you want to save on the electric bill.
[13:16:13] <CaptHindsight> lol
[13:16:19] <Wolf_> heh
[13:16:29] <Jymmm> FinboySlick: Actually, below... (just a sec)...
[13:16:41] <FinboySlick> Ah, comes from the ground?
[13:16:53] <Jymmm> yep
[13:16:54] <Wolf_> I wish I had underground service here, I know how to do y splices on that stuff :D
[13:17:06] <FinboySlick> Dig a tunnel underneath, great-escape style.
[13:17:19] <enleth> Jymmm: one more small point of trivia to remember: typical breakers are not selective during a short circuit. In other words, more than one breaker in series can and often will trip on a short even if their rated amperages are different and in a descending (towards the load) sequence
[13:17:38] <FinboySlick> Only works if you whistle though. Or was that bridge over the river Kwai?
[13:17:43] <enleth> Jymmm: this is usually not a problem because shorts on line voltage should not happen often if ever
[13:18:31] <enleth> Jymmm: but if you expect them and wont't tolerate things turning off all over the place, you have to work around that limitation
[13:18:34] <maxcnc> Hi Q on XHC hb04 IS it posibal to access the lcd entry between MC and Wc direct
[13:18:41] <Jymmm> FinboySlick: http://i.imgur.com/B0qXNaw.jpg?1
[13:19:26] <FinboySlick> Unicorn Industries? They definitely won't mind electricity magically disappearing before the meter.
[13:19:31] <maxcnc> i only can do the stepsize-up to show 1,10,100,1000
[13:19:39] <Jymmm> FinboySlick: haha
[13:20:01] <Jymmm> FinboySlick: But PG&E might =)
[13:20:08] <enleth> Wait, that breaker was $20? Is that a normal US price for a double pole 20A?
[13:20:42] <Jymmm> enleth: That breaker in the stores is $65 - an oddball
[13:20:53] <enleth> what.
[13:21:21] <Jymmm> enleth: 40yo service pole
[13:21:29] <enleth> Is it some special mounting option or something?
[13:21:37] <Wolf_> http://www.ebay.com/itm//262061170546 “Quiet when not running” lmao
[13:21:49] <enleth> I don't recognize this type of rail/whatever it attaches to
[13:22:21] <Jymmm> enleth: It's a "ZINSCO" breaker
[13:22:34] <enleth> Jymmm: is it so expensive because it fits some ancient type of service?
[13:22:35] <roycroft> "zinsco" as in "ancient"
[13:22:38] <enleth> *service pole
[13:22:53] <Jymmm> enleth: pretty much
[13:23:56] <enleth> holy crap
[13:24:23] <justanotheruser> tell me why I shouldn't spend money on building this http://www.shapeoko.com/wiki/
[13:24:37] <JT-Shop> a guy that lived down the street from me shot his meter with a bb gun then stuck a pine needle in to stop the wheel from turning
[13:24:42] <JT-Shop> he finally got caught
[13:24:55] <enleth> You could buy a chinese selective breaker for that price if you looked hard.
[13:25:01] <enleth> I mean, a DIN mount one
[13:25:25] <enleth> and selectives are not cheap, even chinese
[13:25:54] <Jymmm> enleth: Well, this is the breaker I got http://www.ebay.com/itm/181872562658
[13:26:10] <Wolf_> justanotheruser: belt drive? depends on what you plan/expect on cutting with it
[13:26:56] <enleth> > unique design that only fit into load centers (no longer made) that may be labeled Challenger, Sylvaniaor Zinsco
[13:27:05] <enleth> I see
[13:27:22] <justanotheruser> Wolf_: it will vary, but to smart I expect small/precise gears
[13:27:26] <justanotheruser> *start
[13:27:37] <Wolf_> made from what?
[13:28:26] <justanotheruser> likely brass
[13:28:41] <Wolf_> then probably not imo
[13:29:04] <justanotheruser> Not powerful enough? Better off cutting wood and aluminium?
[13:29:24] <Wolf_> better off for engraving/pcb milling probably
[13:29:27] <justanotheruser> also looking into this 8020 http://www.8020cnc.com/cnc%20pics
[13:29:34] <archivist> wrong type of machine for gears
[13:29:35] <justanotheruser> based design
[13:29:40] <CaptHindsight> a unique feature of the ZINSCO was that it would weld itself closed so that it will not trip on overload
[13:30:10] <archivist> justanotheruser, a rigid milling machine not a router
[13:30:14] <justanotheruser> archivist: are you the watch maker from this channel?
[13:30:29] <justanotheruser> I vaguely remember speaking to you before
[13:30:40] <Wolf_> 8020 base might be better, least you can mount THK rails and ball screws on it
[13:31:15] <archivist> justanotheruser, I have been a mainly a clockmaker with some watch parts
[13:31:58] <enleth> justanotheruser: shapeoko would wobble like a damn marshmallow if you try milling gears
[13:32:20] <justanotheruser> what if I made the gears of gold :o
[13:32:33] <enleth> yeah, you could sell them and buy a better machine.
[13:32:44] <enleth> 3. ??? 4. profit!
[13:34:28] <enleth> A CNC'd Proxxon BFW 40E/BFB 2000/KT 150 set is the smallest device I can imagime milling gears, but it's manual OOTB
[13:35:19] <archivist> I would rather use one of the cnc chinese mills than a router design
[13:35:34] <justanotheruser> is brass a "soft metal"
[13:35:51] <enleth> justanotheruser: yeah. It's also slippery and grabby.
[13:36:23] <justanotheruser> What is grabby
[13:36:28] <enleth> When descriptions of shit milling routers mention "soft metals", they probably mean garden variety aluminum.
[13:36:40] <enleth> justanotheruser: it grabs drills
[13:36:43] <archivist> needs little to no rake
[13:36:57] <justanotheruser> ah
[13:37:03] <justanotheruser> the description states "CNC machine must be capable of machining wood (all sorts), plastics and soft metals (aluminum, brass etc). "
[13:37:04] <enleth> I imagine it could grab and pull an end mill under wrong circumstances too.
[13:37:23] <McBride36> so what would you recommend for milling soft metals then
[13:37:25] <archivist> stone your drill to to "brass" them
[13:38:02] <archivist> enleth, not as bad with endmills
[13:38:06] <enleth> McBride36: Sieg KX1 if you want a turnkey purchase
[13:39:19] <justanotheruser> $2000 on alibaba
[13:39:24] <enleth> Its chineseness is within reasonable limits.
[13:39:34] <Jymmm> enleth: FWIW... I'm just duplicating the 220V@20A circuit that is in the front service pole going to a water pump, and replicating it on the rear service pole to feed the garage two 110V@20A circuits
[13:39:46] <justanotheruser> lol
[13:40:03] <McBride36> enleth, what if i wanted the experience of DIY. Assume i have all the tools except for a mill
[13:40:23] <Wolf_> build up a X2 imo
[13:40:26] <enleth> McBride36: then get a Sieg X1/X2 and retrofit it, I guess.
[13:40:41] <Wolf_> X1 sucks, head has too much play
[13:40:45] <enleth> McBride36: a retrofitted X2 could be cheaper than a KX1 if you do it right
[13:41:03] <Jymmm> Is 12ga+12ga=10ga THHN legit/legal to do, beneficial?
[13:41:33] <enleth> Jymmm: you mean pushing a single phase through two conductors?
[13:41:56] <justanotheruser> enleth: /win 53
[13:41:58] <Jymmm> enleth: Basically , yes. I have lots of 12ga thhn
[13:41:58] <justanotheruser> oops
[13:42:12] <enleth> It's legal where I live if you follow certain guidelines and clearly mark it as such, dunno about the US NEC
[13:42:41] <justanotheruser> enleth: any comment on buying these plans for $25? http://www.8020cnc.com/cnc%20pics
[13:42:45] <enleth> But it's not recommended because a partial failure could still go unnoticed for some time
[13:43:24] <Jymmm> ah
[13:43:25] <archivist> justanotheruser, wrong machine for gears
[13:43:52] <McBride36> archivist, what would that machine be for then?
[13:44:00] <archivist> justanotheruser, I am not against home building though
[13:44:06] <justanotheruser> archivist: it is a mill with high precision? http://www.8020cnc.com/images/panel3_large.jpg
[13:44:45] <Wolf_> McBride36: http://littlemachineshop.com/products/product_view.php?ProductID=4962&category=1387807683 makes a ok base for a CNC conversion IMO
[13:44:45] <enleth> archivist: I cringe from just looking at it. In my mind, I see it twisting almost beyond the limits of euclidean geometry under any significant loads.
[13:44:55] <archivist> it is a gantry router
[13:44:59] <enleth> bleh
[13:45:12] <enleth> justanotheruser: ^ I cringe from just looking at it. In my mind, I see it twisting almost beyond the limits of euclidean geometry under any significant loads.
[13:45:34] <justanotheruser> well if I could see non-euclidean geometry irl that would be pretty cool
[13:46:23] <McBride36> enleth, archivist Wolf_ what do you think of this setup http://i.imgur.com/8hsCieH.jpg
[13:46:39] <justanotheruser> archivist: so it is incorrect that it calls itself a milling machine?
[13:46:39] <archivist> justanotheruser, if you are sticking to gears think about a hobbing machine, google gear milling too
[13:46:51] <justanotheruser> archivist: I'd prefer it be able to do more than gears
[13:47:31] <Wolf_> McBride36: not sure wtf that is lol
[13:47:33] <archivist> a lot of the extrusion designs are plain flexible
[13:47:38] <enleth> McBride36: the column looks nice and stout, whatever that is for
[13:47:47] <McBride36> cnc machine believe it or not
[13:47:56] <justanotheruser> The end goal would be to have all the stuff I need for a fab lab
[13:48:06] <justanotheruser> but for now I just want to make gears
[13:48:18] <Wolf_> I can see that, just can see whats used for ways and whatnot
[13:48:20] <justanotheruser> for the first month I own it that is
[13:48:32] <archivist> McBride36, that column has torsional problems
[13:48:48] <McBride36> Wolf_, making tiny injection molds for a medical device manufacturing company
[13:49:00] <archivist> justanotheruser, you need a rotary
[13:49:34] <aventtini> hello guys
[13:49:40] <justanotheruser> There should be a flow chart for figuring out what to buy
[13:49:43] <aventtini> any one on the channel?
[13:49:52] <Wolf_> nope
[13:49:56] <aventtini> :))
[13:50:12] <archivist> aventtini, no all down the pub ask your real question and a bot will answer
[13:50:13] <enleth> McBride36: but the strutrs that connect the vertical plate thing, are there only two of them on the top?
[13:50:23] <aventtini> :))
[13:50:26] <enleth> *struts
[13:50:39] <McBride36> it's a bracket
[13:50:43] <enleth> McBride36: add more along the height of the column or something
[13:50:46] <McBride36> and the plate is bolted at the bottom
[13:50:47] <aventtini> i have a problem joint 2 following error
[13:51:02] <Wolf_> the column looks like a afterthought build on that thing McBride36
[13:51:19] <McBride36> probably is
[13:51:25] <McBride36> i wasn't the one who built it
[13:51:41] <aventtini> i have got the siganl out of the liniar encoders from sin to ttl
[13:52:02] <archivist> McBride36, I first had a column to flexible but made a square/tube to strengthen
[13:52:08] <aventtini> and now i have the drive BOSCH TR15 that has tachos
[13:52:13] <aventtini> on them
[13:52:31] <aventtini> i have corected the speed and f error but still same thing
[13:52:37] <justanotheruser> archivist: could you elaborate on why I need one?
[13:52:48] <archivist> gears are round
[13:53:13] <aventtini> This bosch TR15 old stuff has 2 sw one whit 5 v and one whit 10v
[13:53:17] <justanotheruser> yes, but a mill can cut round shapes, no?
[13:53:29] <archivist> rotate a gear tooth pitch, mill slot, rinse repeat
[13:54:06] <archivist> justanotheruser, the shape has a rectangular root form
[13:54:15] <aventtini> there is by any chance im conected to the 5v sw and the signal is to fast for the drives ?
[13:54:42] <justanotheruser> so I cannot get the precision I need when is rectangle based?
[13:55:24] <archivist> look at the bottom of gear slots http://gears.archivist.info/gears/IMG_1214_hires.JPG
[13:55:48] <archivist> now show me a small enough endmill
[13:56:38] <Wolf_> really its not even square root to most gears right?
[13:56:59] <archivist> use the correct gear form cutter or learn how gears can be generated, I dont count the wooden gear designs as applicable for metal
[13:57:24] <justanotheruser> archivist: why can't I just make a spur
[13:57:36] <aventtini> man thas smalll
[13:58:07] <aventtini> smallest end mill i have used is 0,5mm
[13:58:24] <aventtini> thats made whit a engraving mill
[13:58:29] <archivist> justanotheruser, you normally use a gear cutter and a rotary to make spurs
[13:58:42] <justanotheruser> but I can make spurs with a mill, can't I?
[13:58:56] <archivist> a mill?
[13:59:03] <justanotheruser> milling machine
[13:59:17] <archivist> milling machine with a rotary table
[13:59:26] <justanotheruser> heh
[13:59:34] <justanotheruser> why can't I just cut out the figure with the milling machine
[13:59:48] <Wolf_> the roots will all be rounded
[13:59:55] <archivist> http://www.archivist.info/cnc/target.php
[14:00:01] <aventtini> EDM will be perfect
[14:00:11] <aventtini> on some of them
[14:00:30] <archivist> I cannot imagine edm on a helical
[14:01:36] <aventtini> wire edm
[14:01:41] <enleth> justanotheruser: you can. But it will work badly.
[14:02:06] <archivist> justanotheruser, http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_02_28_cnc/P2210002.JPG
[14:02:08] <aventtini> helical on normal edm electrode made on grafit

[14:04:36] <archivist> manual 5th axis in that
[14:09:44] <archivist> justanotheruser, this is the sort of cutter for normal spur gears http://www.ebay.co.uk/itm/RDGTOOLS-INVOLUTE-VARIOUS-DP-GEAR-CUTTERS-ALL-VARIATIONS-SIZES-TO-CUT-ALL-TEETH-/370710110759
[14:10:07] <archivist> that has a 1" bore for a horizontal mill
[14:10:49] <archivist> just at a few hundred rpm not 20k like a kress on a router
[14:10:59] <Wolf_> here more info then you will ever need about gear cutting https://www.youtube.com/watch?v=JMhYuXx35Ik
[14:12:07] <Wolf_> with a cnc you can swap out the dividing head for a 4th axis (rotating)
[14:13:58] <archivist> hehe he is plain wrong on helical, you can make at home
[14:14:18] <Wolf_> hehe yeah
[14:15:40] <archivist> you can use linuxcnc to hob gears at home too
[14:24:52] <ganzuul> My cutoff tool just chatters...
[14:25:42] <archivist> needs to be sharp, use the slowest speed you can
[14:26:12] <archivist> and lubricate
[14:26:33] <ganzuul> ooh
[14:26:40] <ganzuul> huh
[14:26:49] <Wolf_> archivist: opinion, getting the x2 head in pieces, AC or taper roller bearings?
[14:27:05] <Wolf_> for the r8 spindle...
[14:27:15] <archivist> is that two questions :)
[14:27:27] <ganzuul> Thought it was the same as with cutting the OD on 6061. High speed.
[14:27:52] <archivist> not on a tiny lathe
[14:28:03] <Wolf_> just one, picking bearings
[14:28:54] <archivist> tapers are good for load, the others for high speed, a choice
[14:30:07] <Wolf_> use both? lol taper at the nose end, angular contact at the drive end? lol
[14:30:14] <Sync> I suppose angular contact will be fine
[14:30:45] <Sync> Wolf_: matched pair at the nose and a single one at the drive end
[14:31:02] <archivist> think of you main use, then choose
[14:31:43] <Wolf_> alum and some steel, engraving not often…
[14:32:09] <Sync> also think about your drive
[14:32:09] <archivist> a low speed slab milling cutter, taper roller, high speed al ac
[14:32:21] <Sync> if you use a belt you might exceed radial loads
[14:32:56] <Wolf_> yeah, its going to be a belt drive
[14:34:26] <Wolf_> and the spindle uses 6007RS (35x62x14mm) nose, 6206RS (30x62x16mm) drive end
[14:34:36] <Wolf_> so I don’t think I can stack 2 of anything
[14:34:47] <Sync> probably not without machining the case
[14:35:12] <Wolf_> case is hollow, I don’t think machining is going to work
[14:35:48] <Sync> machine the case completely hollow and glue in a bearing cartridge
[14:37:50] <justanotheruser> archivist: Alright, I'm a bit disappointed that I will need a separate machine, but is there one you would recommend?
[14:38:20] <Wolf_> http://damonjurkiewicz.com/frankenmill-phase-1/ has some good pics of the x2 spindle head
[14:39:46] <archivist> justanotheruser, I would recommend retrofitting an industrial mill for best, depends on gears sizes you want to make
[14:40:26] <archivist> sometimes easier to buy ready made gears
[14:40:43] <archivist> then you need a lathe to adapt them
[14:41:05] <archivist> you need a lathe to make blanks anyway
[14:41:16] <justanotheruser> Why would I retrofit a mill? Should I have a rotary that the mill machine reduces from?
[14:41:40] <archivist> reduces?
[14:42:00] <justanotheruser> cuts from
[14:42:17] <ganzuul> Meh.
[14:42:25] <ganzuul> I can't experiment at this hour.
[14:42:33] <archivist> noise :)
[14:42:49] <ganzuul> Yeah. Steel and brass are really quiet.
[14:43:08] <archivist> justanotheruser, I think you are confused about normal gear cutting processes
[14:43:14] <justanotheruser> probably
[14:43:23] <justanotheruser> maybe I should read into it more and come back
[14:43:38] <archivist> I had to stop playing with the CMM as the compressor is noisey
[14:43:46] <Wolf_> justanotheruser: https://www.youtube.com/watch?v=JMhYuXx35Ik
[14:43:51] <Sync> get a co2 bottle archivist
[14:44:07] <justanotheruser> this is the tutorial I saw https://www.youtube.com/watch?v=_Y-_13eYwBQ
[14:45:24] <ganzuul> Funny though, when the tool bites into the aluminium the chuck stops, then the motor starts adding up power until it frees the tool, getting a rather nice chip. I'm maybe running at at too slow a speed, or need an even sharper tool.
[14:45:25] <CaptHindsight> fill the t-slot column with epoxy granite and attached if more firmly to the Z positioner
[14:46:02] <CaptHindsight> http://i.imgur.com/8hsCieH.jpg ^^
[14:46:47] <archivist> Sync, that would explode all the pipes in it
[14:46:47] <CaptHindsight> archivist: how rapidly does the CMM move?
[14:47:07] <archivist> CaptHindsight, not at all yet, effin crap software
[14:47:26] <archivist> flashes an error so fast I cannot read it
[14:47:43] <CaptHindsight> archivist: is there a manual mode?
[14:47:57] <archivist> cant get past the himing
[14:48:05] <archivist> homing
[14:48:12] <CaptHindsight> screw driven?
[14:48:41] <archivist> no it has servos driving by friction onto rods
[14:49:04] <Sync> there are regulators for them archivist
[14:49:25] <archivist> the servos lock it on all 3 axes on start
[14:49:57] <Wolf_> hmm, i might go taper bearing, especially with the air cylinder draw bar setup
[14:50:05] <archivist> so I think it is more a software issue (licence ?)
[14:50:23] <archivist> it has its dongle
[14:52:29] <CaptHindsight> http://www.ebay.com/itm/Mikron-A-2-1-0-Hob-Gear-Cutter-hobbing-machine-/231701056064 $1300 or best
[14:53:20] <archivist> Sync, too costly I think, needs about 2,5 cfm
[14:56:04] <archivist> £185+VAT at 20% for 262 minutes of use!
[14:56:45] <kanzure> justanotheruser: there are many better things to make rather than shapeoko things
[14:58:31] <Sync> the filling is much cheaper archivist
[14:58:47] <Sync> I pay like 12€/10kg at my local gas dealer
[14:59:39] <ganzuul> How do I know if a random drill-rod like bit of steel is actually drill rod?
[15:01:06] <Sync> XRD
[15:01:59] <ganzuul> ...Oh poop. This has already been hardened.
[15:03:26] <ganzuul> ...man this stuff is hard.
[15:04:33] <archivist> Sync, I would need 60 kg a day
[15:04:49] <Sync> if you use it solely
[15:05:04] <Sync> but to supplement a compressor it works nicely
[15:05:16] <Sync> I have a bottle around for situations like that
[15:05:43] <ganzuul> You can get HPA in scuba tanks.
[15:06:19] <ganzuul> Mind you those tanks are not a joke.
[15:06:55] <ganzuul> Knock the valve off and you got yourself a rocket.
[15:07:09] <Sync> you don't
[15:07:17] <Sync> as all legal tanks have a blow off valve
[15:08:02] <ganzuul> Archivist strikes me as the kind of guy who is legal when it suits him.
[15:08:38] <justanotheruser> kanzure: yeah, I am wondering why a hobbing machine isn't in your fablab kit
[15:09:40] <Sync> oh that is a teeny tiny machine CaptHindsight
[15:09:56] <kanzure> justanotheruser: because literally nobody has reviewed that list
[15:10:01] <archivist> justanotheruser, https://www.youtube.com/watch?v=PFTHY5U8v-U
[15:10:50] <CaptHindsight> Sync: http://www.ebay.com/itm/BARBER-COLEMAN-14-15-GEAR-HOBBER-HOBBING-MACHINE-/281662834610 this more like it?
[15:11:23] <justanotheruser> archivist: do I still want a hobbing machine if my gears are going to be 1-2mm thick?
[15:11:32] <archivist> that is a large lump buy it for me
[15:11:50] <CaptHindsight> will you cover the shipping?
[15:12:08] <archivist> justanotheruser, it is the fastest way to make gears
[15:12:28] <Sync> yup CaptHindsight
[15:12:28] <archivist> CaptHindsight, erm...cannot afford the shipping either
[15:12:42] <Sync> shipping probably is not expensive
[15:13:49] <archivist> I dont have full time employment
[15:15:18] <ganzuul> To answer my own question: I can find out how it anneals...
[15:15:23] <archivist> barber colman and mikron were the two main hobbing machine makers
[15:16:09] <archivist> my baby barber colman is damned heavy
[15:16:27] <Sync> I'm thinking about getting a pfauter
[15:16:59] <ganzuul> http://www.spaco.org/Blacksmithing/Anneal/AshBucketAnneal.htm
[15:18:55] <CaptHindsight> https://www.youtube.com/watch?v=G66YH2EGbDA look at how rigid the cutter is on this
[15:19:08] <CaptHindsight> Hofler HF 4000 Gear Hobbing Machine ^^
[15:21:05] <archivist> that looked like it has its own gashing
[15:24:04] <Sync> in the end gear hobbing is not hard but you want a dedicated machine for it
[15:24:33] <CaptHindsight> lathe with live tooling
[15:24:56] <Sync> I also want a gear grinder, or rather a diaform to shape the discs
[15:25:04] <archivist> Sync, you can now do it on a normal mill if it has spindle encoder
[15:25:24] <norias> i think being a machinist has me...
[15:25:26] <norias> spoiled
[15:25:36] <norias> if i send a resume and i don't hear back in 3 days
[15:25:41] <norias> i'm a little miffed
[15:25:56] <archivist> with modern software gearing you can use more hardware for hobbing
[15:26:21] <CaptHindsight> https://www.youtube.com/watch?v=NsN72k5Ne9c hobbing on CNC lathes without B-axis
[15:26:43] <skunkworks_> https://www.youtube.com/watch?v=ZhICrb0Tbn4
[15:29:47] <Sync> sure, but I'd rather have a dedicated machine
[15:31:16] <archivist> I can only get about 1" diameter on mine
[15:32:05] <archivist> was really a production watch gear machine
[16:01:57] <MacGalempsy> good afternoon all

[16:35:25] <Sync> yes
[16:35:46] <XXCoder> you didnt see guide: how to shave with HSS drills?
[16:37:55] <Loetmichel2> ganzuul: a small HSS blade certainly
[16:38:20] <Loetmichel2> a drill or similar simply has not a small enough angle of attack
[16:39:19] <Loetmichel2> my HSS wood chisesls and plane blades certainly can be used as a razor
[16:39:21] <Loetmichel2> with ease
[16:41:50] <ganzuul> ooh
[16:43:41] <ganzuul> Tryina get this HSS parting tool as sharp as possible on the underside of a cup.
[16:44:27] <Loetmichel2> <- uses the diamond file on his leatherman wave for this kind of thing
[16:44:44] <Loetmichel2> and up to 2000grit sandpaper glued to a glass plate
[16:48:01] <ganzuul> The raised edge lets me get into the chip breaker.
[16:51:28] <ganzuul> eeh, good enough. Bites into aluminium at the right angle.
[17:03:36] <JT-Shop> I know I have two pocket hole jigs but can't find either of them... I guess I'm about to own a third one
[17:12:10] <_methods> kreg?
[17:12:18] <_methods> always good to have a few of those around
[17:12:44] <roycroft> i have one, and i've had it for about 20 years
[17:12:53] <roycroft> it lives in a drawer labeled "kreg jig"
[17:13:28] <_methods> mine is attached to the side of my chopsaw table
[17:13:53] <roycroft> so if you lose your chopsaw table you're sol
[17:13:58] <_methods> yep
[17:14:05] <_methods> no chopsaw and no kreg jig lol
[17:14:18] <_methods> fubar'd
[17:14:58] <JT-Shop> yea kreg
[17:15:18] <_methods> i have an old aluminum one somewhere
[17:15:34] <_methods> not sure where that one is hiding though
[17:15:50] <_methods> i was determined to keep the blue plastic one from disappearing
[17:16:06] <_methods> made it a special home on the chopsaw stand
[17:16:10] <JT-Shop> I have the mini ones http://www.amazon.com/Kreg-MKJKIT-Mini-Jig-Kit/dp/B00065WPP2/ref=sr_1_3?ie=UTF8&qid=1443477099&sr=8-3&keywords=kreg+pocket+hole+jig
[17:16:34] <_methods> yeah one of those came in my kit
[17:16:47] <_methods> that's the emergency one hehe
[17:17:55] <roycroft> mine is the original one
[17:17:57] <roycroft> single hole
[17:24:52] <MacGalempsy> ganzuul: I bet razorblades are no more than hdd
[17:39:25] <JT-Shop> mmm Dakgangjeong for dinner tonight
[17:39:57] <_methods> bless you
[17:40:40] <_methods> ahh fried chicken
[17:40:48] <_methods> had to look that one up
[17:44:58] <JT-Shop> very good too
[17:55:07] <_methods> yeah that looks tasteeee
[18:54:36] <McBride36> anyone ever built a bartending bot in here?
[18:55:16] <SpeedEvil> Aren't some lathes basically bartending robots?
[18:56:00] <McBride36> i've only turned bowls on mine so...IDK?
[19:01:17] <MacGalempsy> JT-Shop: what exactly is Dakgangjeong? Vietnamese?

[20:02:01] <zeeshan-mill> theres gotta be a safer way
[20:02:05] <zeeshan-mill> to not hit ok on that dialog box
[20:02:07] <malcom2073> Yes, a second computer for that :P
[20:02:20] <zeeshan-mill> not in garage :(
[20:02:25] <malcom2073> Yes in garage
[20:02:29] <malcom2073> Or a tablet
[20:03:08] <malcom2073> I'ma laugh when you have a tool crash, because a flash player in the background locks up the system for a moment
[20:03:54] <zeeshan-mill> lol
[20:03:59] <zeeshan-mill> i dont surf websites
[20:03:59] <zeeshan-mill> just pdf
[20:04:13] <zeeshan-mill> still got e-stop :D
[20:05:36] <malcom2073> Heh
[20:33:18] <PetefromTn_> I use my laptop or smartphone
[20:36:59] <zeeshan-mill> hehe
[20:37:06] <zeeshan-mill> PetefromTn_, that company that asked me to bid
[20:37:11] <zeeshan-mill> asked me to prototype those pieces for them
[20:37:18] <zeeshan-mill> it seems like the other comapny fell through
[20:37:22] <zeeshan-mill> we might still get it.
[20:37:28] <PetefromTn_> HOLY SHIT
[20:37:34] <zeeshan-mill> don;t hold your breath though!!
[20:37:37] <zeeshan-mill> these guys are cheapies
[20:37:43] <PetefromTn_> aw
[20:37:49] <zeeshan-mill> they might be using me for prototype only
[20:37:52] <PetefromTn_> I actually have some work going on here now
[20:38:09] <PetefromTn_> but yeah if they want me to make em I can DO IT
[20:38:25] <PetefromTn_> ya know its funny I told my wife about that job
[20:38:29] <zeeshan-mill> good to know you got my back
[20:38:33] <PetefromTn_> and the number of parts
[20:38:41] <PetefromTn_> and she was like WOAH
[20:39:05] <PetefromTn_> How in the hell are you going to make all those parts LOL
[20:39:21] <PetefromTn_> and I had to say ......Hell I don't know hehehe
[20:39:33] <PetefromTn_> just kidding
[20:40:38] <PetefromTn_> trying to buy another Fiero GT here because I am weird and have some sorta psychological problem
[20:41:56] <zeeshan-mill> hahaha
[20:42:00] <zeeshan-mill> dude i was asking my wifey
[20:42:06] <zeeshan-mill> if she could run the machines too
[20:42:10] <zeeshan-mill> *machine
[20:42:16] <PetefromTn_> LOL I do the same thing..
[20:42:29] <PetefromTn_> She's like I don't know how to do that....
[20:42:43] <zeeshan-mill> easy
[20:42:46] <zeeshan-mill> press a button
[20:42:46] <zeeshan-mill> load a tool!
[20:42:47] <PetefromTn_> I told her I would only let her run them once I have a TOTALLY PROVEN PROGRAM
[20:42:55] <PetefromTn_> I think she can do it
[20:43:00] <zeeshan-mill> i think you gotta let her see what sounds wrong
[20:43:03] <zeeshan-mill> and what sounds normal
[20:43:09] <zeeshan-mill> and if the tool is loaded correctly
[20:43:10] <PetefromTn_> but I need to have a CNC lathe to run to get away with it ;)
[20:43:17] <zeeshan-mill> haha
[20:43:31] <PetefromTn_> ya know what is really funny
[20:43:43] <PetefromTn_> last two weeks I had a BUNCH of rail sales
[20:43:51] <PetefromTn_> and I almost have them all done now
[20:44:01] <PetefromTn_> and I told her how much we made on them
[20:44:22] <PetefromTn_> she was like YOU GOTTA BE KIDDING ME that is more than she makes working overtime LOL
[20:44:41] <PetefromTn_> I only wish I had that many orders all the time
[20:44:42] <malcom2073> How many parts you looking at?
[20:44:56] <PetefromTn_> I would be working in the shop and not for anyone else
[20:45:04] <zeeshan-mill> PetefromTn_, very nice man
[20:45:07] <zeeshan-mill> its nice when the orders are coming
[20:45:23] <PetefromTn_> yeah I need to design some more cool rails for other guns here
[20:45:32] <malcom2073> If you got the guns, why not
[20:45:39] <PetefromTn_> That is my problem
[20:45:45] <PetefromTn_> I can't afford the damn guns LOL
[20:45:53] <PetefromTn_> freaking things are expensive
[20:45:58] <malcom2073> Find a friend with the gun, and offer them a free rail for letting you borrow it? :P
[20:46:10] <PetefromTn_> that Steyr alone is like $3600.00
[20:46:14] <zeeshan-mill> malcom2073, how dare you say if you had the guns
[20:46:16] <zeeshan-mill> have you not seen his servos
[20:46:20] <malcom2073> Lol
[20:46:21] <zeeshan-mill> they're BAWS!!!
[20:46:22] <PetefromTn_> well that is actually kinda what I do
[20:46:43] <PetefromTn_> yeah baby ;)
[20:46:46] <malcom2073> Haha
[20:46:53] <malcom2073> I have tiny steppers, I have no room to talk about motors :P
[20:46:57] <zeeshan-mill> haha osrry man
[20:47:00] <zeeshan-mill> i love picking on you about that
[20:47:12] <PetefromTn_> I remember when I ordered the new servos for the Cinci
[20:47:22] <PetefromTn_> I got them here and was like WOW these are HUGE LOL
[20:47:27] <zeeshan-mill> the wallet drained!
[20:47:29] <PetefromTn_> and in reality they are actually small ones
[20:47:47] <malcom2073> zeeshan-mill: I promise someday I'll go back to servos
[20:48:01] <malcom2073> maybe I'll make enough money on my mill to be able to pay for it heh
[20:48:04] <zeeshan-mill> malcom2073, a machine is better than no machine
[20:48:09] <zeeshan-mill> whether is stepper or servo..
[20:48:14] <zeeshan-mill> both will get the job done
[20:53:11] <zeeshan-mill> PetefromTn_, you got all new servos for x y z?
[20:53:13] <zeeshan-mill> $$$$
[20:53:31] <PetefromTn_> yeah
[20:56:49] <MacGalempsy> I like the idea of putting wives to work in the CNC shop
[20:58:08] <zeeshan-mill> lol
[20:58:23] <zeeshan-mill> i love my wifey
[20:58:26] <zeeshan-mill> she does everything for me
[20:58:27] <zeeshan-mill> shes the best
[20:58:30] <zeeshan-mill> best partner ever :D
[20:58:38] <zeeshan-mill> she helped move the mill
[20:59:18] <zeeshan-mill> "key to zeeshans heart -- move his machines"
[21:00:13] <Wolf_> 0.o what I miss...
[21:03:59] <Wolf_> not very much…
[21:04:33] <zeeshan-mill> lol
[21:06:05] <Wolf_> going to order one of them sewing machine drive motors
[21:06:18] <skunkworks> any spindle synced motion videos?
[21:06:20] <skunkworks> http://www.cnczone.com/forums/linuxcnc-formerly-emc2-/283236-cnc.html
[21:06:38] <malcom2073> andy has a couple
[21:07:19] <skunkworks> I think I have most of his
[21:09:19] <MacGalempsy> as long as its a qualified workpiece =)
[21:11:17] * furrywolf flops over exhausted
[21:17:42] <zeeshan-mill> so quiet here!!
[21:17:44] <zeeshan-mill> entertain me!
[21:18:02] <PetefromTn_> I work on race cars...
[21:18:10] <malcom2073> Me too!
[21:18:11] <PetefromTn_> ;)
[21:18:18] <malcom2073> Except mine don't go very fast, since they're always broken
[21:18:31] <furrywolf> got your lump done? ready for him to place an order of 1000? :P
[21:18:38] <os1r1s> PetefromTn_: malcom2073 What do you think of the tesla p85d?
[21:18:51] <PetefromTn_> you guys ever heard the jerky boys?
[21:19:37] <malcom2073> os1r1s: Not really my kind of race car heh
[21:19:51] <PetefromTn_> os1r1s Don't know much about it. I know I like Tesla and the Model S hauls major ass LOL
[21:19:54] <zeeshan-mill> furrywolf, soon :P
[21:19:58] <zeeshan-mill> im working on other jobs tonight
[21:20:11] <os1r1s> malcom2073: I have a 67 mustang and a 06 porsche I race. But the tesla has my eye.
[21:20:33] <malcom2073> Yeah, I don't much care for things beyond my price range heh
[21:20:53] <PetefromTn_> https://www.youtube.com/watch?v=ZXWo6jXmRO8 Some foul language so if that bothers you Don't click LOL
[21:22:14] <furrywolf> teslas are way, way out of my budget.
[21:22:54] <PetefromTn_> I know I would enjoy a Tesla powertrain from the roadster in my Fiero GT hehehe
[21:22:54] <furrywolf> let's spend 6 years' income on a vehicle! ... nope.
[21:23:04] <os1r1s> PetefromTn_: I'm old like you. I remember them.
[21:23:17] <PetefromTn_> Hey screw you man I am NOT OLD!!
[21:23:20] <PetefromTn_> LOL
[21:23:27] <os1r1s> haha
[21:23:31] <PetefromTn_> I am only 45
[21:23:42] <PetefromTn_> Old is like .....55
[21:23:48] <PetefromTn_> hehe
[21:24:01] <furrywolf> old is (my age) + 10? :P
[21:24:12] <zeeshan-mill> PetefromTn_, have you seen the 2015 mustang?
[21:24:14] <zeeshan-mill> its so sexy
[21:24:20] <zeeshan-mill> i rarely like mustangs
[21:24:23] <zeeshan-mill> except the shelbys
[21:24:31] <zeeshan-mill> but boy.. this one is sexy!
[21:24:43] <PetefromTn_> I agree they did a nice job with it
[21:24:50] <PetefromTn_> I like the width and the roofline
[21:24:55] <zeeshan-mill> and youre not old until youre dead!
[21:24:57] <zeeshan-mill> yea
[21:24:58] <PetefromTn_> and the tail lights are sweet
[21:25:00] <zeeshan-mill> the rear fenders!!
[21:25:01] <zeeshan-mill> ad tails
[21:25:02] <zeeshan-mill> wow!
[21:25:11] <PetefromTn_> Did you see the Mazda RX9?
[21:25:14] <zeeshan-mill> no
[21:25:24] <PetefromTn_> It is a disappointment I am afriad
[21:25:30] <PetefromTn_> its a damn four door car
[21:25:42] <PetefromTn_> its a pretty good looking four door car
[21:25:53] <PetefromTn_> but Where the hell did the RX7 get four doors from?
[21:26:08] * furrywolf likes station wagons
[21:27:34] <PetefromTn_> there is a guy who lives down the road from me who just bought a classic Volvo P1800 and it is pretty sweet
[21:27:55] <zeeshan-mill> four door!
[21:27:56] <zeeshan-mill> wtf!
[21:28:40] <PetefromTn_> I know right
[21:28:45] <PetefromTn_> WTH?
[21:29:07] <zeeshan-mill> mazda really doesnt make any cool cars anymore..
[21:29:36] <PetefromTn_> the new Miata is kinda cool but yeah generally not
[21:29:48] <zeeshan-mill> yes thats theo nly thing they got going for em
[21:29:53] <zeeshan-mill> rwd sports car
[21:29:56] <zeeshan-mill> but its slow oem
[21:30:02] <zeeshan-mill> its not like the fc rx7 or fd rx7
[21:30:05] <zeeshan-mill> that were quick from facotyr
[21:30:13] <zeeshan-mill> and had everything else (good handling, looks etc)
[21:30:35] <PetefromTn_> agreed
[21:30:50] <furrywolf> I don't think anyone makes a cool car anymore... teslas are shiny, but the price makes them uncool.
[21:30:52] <PetefromTn_> they just got a SICK SWEET Toyota Supra in the shop today
[21:31:05] <PetefromTn_> its all black
[21:31:12] <PetefromTn_> very clean
[21:31:17] <PetefromTn_> big turbo
[21:31:25] <PetefromTn_> hard not to like those cars
[21:31:41] <PetefromTn_> they now have three different ones they are building in the shop
[21:32:08] * furrywolf has very different tastes in cars, apparantly. :P
[21:32:12] <PetefromTn_> the badass RX7 that I worked on the motor for they put in the car the other day
[21:32:37] <PetefromTn_> and they got this awesome high flow cast dual fuel injector bank intake for it
[21:32:46] <PetefromTn_> and when they put it all in the car
[21:32:54] <PetefromTn_> the HUGE turbo would not fit where it was before
[21:33:06] <PetefromTn_> so now I am making a whole new turbo manifold for the car
[21:33:12] <furrywolf> zee has that problem too.
[21:33:25] <PetefromTn_> it has to move the turbo forward and down quite a bit to clear
[21:33:38] <furrywolf> he stuck his up high
[21:34:14] <PetefromTn_> that is a BIG ass turbo man... I don't remember what model or size but it barely fits in the engine bay
[21:34:32] <furrywolf> I think he has two of them. :)
[21:34:41] <zeeshan-mill> theres lots of room in a rotary
[21:34:44] * furrywolf has never owned anything with a turbo
[21:35:08] <zeeshan-mill> but rotaries also like big ass turbos
[21:35:16] <furrywolf> when you're a redneck, rather than turbos, you add useful accessories like lift kits, swampers, locking differentials, gun racks, etc. :P
[21:35:19] <Wolf_> 2 out of 4 i have right now have turbos...
[21:35:26] <zeeshan-mill> Wolf_, diesels dont count!!!
[21:35:26] <zeeshan-mill> :P
[21:35:28] <zeeshan-mill> jk
[21:35:44] <Wolf_> I was about to say they are missing spark plugs :P
[21:35:51] <zeeshan-mill> hehe
[21:37:42] <Wolf_> ok, sewing machine brushless ordered, that should be fun to figure out when it gets here ;)
[21:38:42] <PetefromTn_> http://imgur.com/FVdvj2g BIG TURBO
[21:39:25] <CaptHindsight> with nitrous?
[21:39:53] <malcom2073> CaptHindsight: It's called nawz
[21:40:04] <PetefromTn_> no nitrous
[21:40:25] <CaptHindsight> washing machine
[21:40:36] <PetefromTn_> Hair dryer ;)
[21:41:59] <PetefromTn_> Can't wait to see that car fire up
[21:42:03] <CaptHindsight> are they scared of blowers or something?
[21:42:08] <PetefromTn_> it is pretty awesome
[21:42:22] <PetefromTn_> blowers are parasitic....turbos are not
[21:42:37] <CaptHindsight> don't they want any power at lower rpm's?
[21:42:49] <PetefromTn_> but we just put a brand new Ecotec blown motor in a cobalt SS if that counts LOL
[21:42:53] <malcom2073> You don't race at low rpm
[21:43:10] <CaptHindsight> kids these days
[21:43:35] * furrywolf likes low-end power
[21:43:50] <PetefromTn_> the rotary motor actually makes reasonable power down low and a lot of it depends on the turbo setup how quickly it spools etc...
[21:44:04] <zeeshan-mill> nawwwwwwwwwwwwz
[21:44:05] <zeeshan-mill> !!!!!!!!!!11
[21:44:12] <zeeshan-mill> yea malcom you know the terms
[21:44:12] <zeeshan-mill> :D
[21:44:14] <PetefromTn_> I can tell you I got a ride in a 500 HP RX7 the other day....
[21:44:24] <PetefromTn_> there was NO problem with any of that LOL
[21:45:01] <PetefromTn_> that car really hauls ass man...I mean like plant you in the seat and keep you there kinda hauling ass....
[21:45:42] <PetefromTn_> I can't imagine what one with around 1k HP will be like
[21:46:05] <furrywolf> my subaru really pulls... I used it and a few heavy chains to drag a chevy truck with flat tires up steep ramps onto a high trailer... :P
[21:46:12] <PetefromTn_> apparenlty some jamaican guys just built a 2 rotor motor that made 1200 HP this past week
[21:47:10] <CaptHindsight> I think that gap between '74 and the early 90's caused a complete change in car culture
[21:47:16] <CaptHindsight> the smog years
[21:48:10] <PetefromTn_> https://www.youtube.com/watch?v=7YPyU1v1Woc MONSTER ROTARY
[21:48:23] * furrywolf likes vehicles that pull! ... just a different definition of pull that people here seem to use.
[21:50:11] <PetefromTn_> https://www.youtube.com/watch?v=67q7uanP4fU
[21:51:47] <Wolf_> this count as pulling? http://i1139.photobucket.com/albums/n541/wolfmetalfab/Ranger/467F63FE-E29B-4479-8B50-40BE12E06D62-7566-000007957887C647.jpg
[21:56:11] <PetefromTn_> heh
[21:56:29] <PetefromTn_> I guess I am turning into a turbo junkie working over there LOL
[21:56:38] <Wolf_> lol
[21:59:33] <CaptHindsight> ouch, leaf spring mount go boom
[22:00:02] <Wolf_> heh yup, there is a hole in the bed from it too
[22:00:13] <CaptHindsight> Wolf_: the floor pan looks good yet the mount has completely disintegrated
[22:01:11] <CaptHindsight> good thing you had just stocked up on 6 months of supplies :)
[22:01:24] <Wolf_> that truck ended up getting new upper/lower control arms, new shackles and mounts, new exhaust, new tie rod ends…
[22:07:33] <zeeshan-mill> god im a moron
[22:07:40] <zeeshan-mill> i dropped a 246 block on my foot
[22:07:45] <zeeshan-mill> and i was wearing sandles
[22:07:48] <zeeshan-mill> serves me right.
[22:07:59] <CaptHindsight> you should try to avoid that
[22:08:00] <[cube]> ouch!
[22:08:03] <zeeshan-mill> have to go to the er cause i broke my toe
[22:08:09] <[cube]> geeez
[22:08:22] <[cube]> good luck dude
[22:08:22] <zeeshan-mill> i used two stablized wood sticks
[22:08:30] <zeeshan-mill> and zip ties
[22:08:35] <zeeshan-mill> to keep the toe straight
[22:08:35] <zeeshan-mill> lol
[22:08:43] <[cube]> damn
[22:08:52] <CaptHindsight> driving yourself?
[22:08:59] <zeeshan-mill> CaptHindsight, yes
[22:09:02] <zeeshan-mill> still got the other foot
[22:09:09] <zeeshan-mill> gonna take automatic car
[22:09:34] <zeeshan-mill> plz guys dont wear sandles and shorts inyour shop
[22:09:40] <zeeshan-mill> learn from a moron like me
[22:10:11] * furrywolf wears steeltoes all day, milling or not. just a good idea.
[22:10:52] <furrywolf> I keep them next to the bed, put them on when I get up, and take them off when I get into bed at night. hopefully nothing happens to my feet in bed...
[22:10:59] <[cube]> lol
[22:11:33] <SpeedEvil> stabilised wood sticks?
[22:11:39] <CaptHindsight> the argument against steel toes is that if it's heavy enough it keeps the metal crushed on your toes
[22:11:43] <SpeedEvil> concerned about humidity?
[22:11:51] <CaptHindsight> vs bounces off
[22:11:56] <SpeedEvil> CaptHindsight: that seems like an argument against seatbelts too
[22:12:16] <Praesmeodymium> plastic caps were my answer, but thats because they do not make steel caps in y width
[22:12:17] <[cube]> i got some 'steel toe' boots from walmart, altho i'm pretty sure they're just hard resin i'd bet
[22:12:19] <furrywolf> CaptHindsight: I think the tests have shown that if it's heavy enough to do that, rather than bouncing, it'll crush your toes flat.
[22:12:23] <Praesmeodymium> *my
[22:12:29] <SpeedEvil> furrywolf: ''
[22:12:48] <Praesmeodymium> 7e width makes shoes hard to fit
[22:12:52] <CaptHindsight> I only use marine plywood for my splints
[22:13:14] <SpeedEvil> Praesmeodymium: considered clogs? Titanium with lightening holes.
[22:13:27] <SpeedEvil> Milled from a solid billet
[22:13:41] <CaptHindsight> hmm, steel toed shop sandals
[22:14:09] <CaptHindsight> I could make a fortune in warm machine climates
[22:14:11] <Praesmeodymium> my steel toed tevas would makeme the envy of every hipster as I kick the shit outta em
[22:14:19] <furrywolf> the guy I got my mill from does custom shoe inserts... first step is a 3d scan of the person's feet. I bet he could make milled-to-perfectly-fit-foot titanium clogs too.
[22:14:43] * SpeedEvil imagines articulated plate-armour for feet.
[22:14:52] <CaptHindsight> flip flops with toe guards
[22:14:52] <[cube]> titanium is too soft! and hard to machine
[22:14:58] <furrywolf> SpeedEvil: I have both imagined and started designing such a thing.
[22:15:08] <SpeedEvil> furrywolf: you are a very silly wolf in the best ways.
[22:15:13] <furrywolf> SpeedEvil: mostly for nail puncture protection on jobsites.
[22:15:36] <furrywolf> you have to have completely interlocking plates or nails will find a way through, which is hard.
[22:15:41] <CaptHindsight> this is even better than my snow sandals idea!
[22:16:13] <Wolf_> nails in foot suck
[22:16:34] <SpeedEvil> steel belted tyres are quite nail resistant
[22:16:55] <SpeedEvil> I guess the question is how hard to you want to be able to stamp on a nail
[22:16:56] <furrywolf> ... and yet I seem to get nails in them quite regularly.
[22:17:19] <SpeedEvil> furrywolf: you don't weigh 1200 pounds and run at 50MPH
[22:17:22] <SpeedEvil> ... I hope
[22:17:45] <PetefromTn_> jeez did he really break his toe?
[22:17:54] <furrywolf> no, I'm a lot lighter than that. :P
[22:17:57] <CaptHindsight> think so
[22:18:19] <PetefromTn_> damn a 246 block is kinda heavy tho
[22:18:32] <furrywolf> and did he really IRC about it before seeking medical attention? that might be bashworthy.
[22:18:41] <SpeedEvil> My machinist-fu is weak.
[22:18:52] <SpeedEvil> Is that a 2"*4"*6" block of steel?
[22:19:08] <Wolf_> yeah, setup block
[22:19:09] <SpeedEvil> With nice sharp corners?
[22:19:13] <[cube]> Item Weight: 20 pounds
[22:19:18] <furrywolf> very, very sharp corners.
[22:19:30] <Wolf_> and hardened
[22:19:37] <[cube]> yeah that'll make a dent
[22:19:38] <SpeedEvil> There aren't many good ways to catch that on your foot
[22:19:59] <[cube]> maybe in one of the holes
[22:20:08] <[cube]> on the way down
[22:20:10] <furrywolf> best way is with your steeltoed boots like you should be wearing around heavy things. :P
[22:20:31] <SpeedEvil> at that shape, it'll fuck up your legs too
[22:20:43] <SpeedEvil> but feet are more likely victims
[22:21:02] <CaptHindsight> it's best to just keep them off and away from feet
[22:21:10] <PetefromTn_> no sharp corners
[22:21:35] <PetefromTn_> just like 123 blocks only larger
[22:21:53] <PetefromTn_> usually have champfered corners to allow stacking without locking chips in corners etc.
[22:22:27] <furrywolf> hrmm, the 123 blocks I had had ground sharp corners... the kind you get when you grind the sides and do nothing to the corners.
[22:22:35] <CaptHindsight> http://www.shars.com/246-precision-block
[22:22:45] <CaptHindsight> Chinese versions
[22:22:56] <Valen> CaptHindsight: myth busted, if you press down hard enough to deform the metal its already cut your toes off
[22:23:24] <[cube]> i'd perfer a clean cut to a bone-crushing smash
[22:23:34] <CaptHindsight> Valen: sure it depends on the design of the metal toe
[22:24:00] <CaptHindsight> steel foil vs 1/2" plate
[22:24:14] <SpeedEvil> [cube]: yeah - but the number of times you're going to get an actual nice edge cutting your toes off in a manner to easily reattach...
[22:24:17] <PetefromTn_> well gotta get some work done out here...
[22:24:20] <PetefromTn_> BBL
[22:24:26] <Valen> http://mythbustersresults.com/episode42
[22:24:30] <[cube]> haha true
[22:24:46] <Valen> they are (hopefully) designed to a spec ;-P
[22:25:13] <furrywolf> mine come with some tag about the specs they meet
[22:25:13] <SpeedEvil> Valen: It sounded a hell of a lot like one of those 'safety equipment facts' that people make up so as to not wear safety gear.
[22:25:24] <SpeedEvil> 'safety belts will trap you in a burning car'
[22:26:04] <furrywolf> I'm all for letting people not wear safety gear, as long as they're willing to accept the consequences of their decisions, not be a parasite, and if they have kids, have life insurance...
[22:26:40] <furrywolf> I wear my seatbelt. I don't think it should be a law. If it were not a law, I'd still wear it, however.
[22:26:51] <CaptHindsight> https://www.onlinemetals.com/prodimg/pichrret.jpg maybe something like this for toe protection
[22:26:51] <SpeedEvil> As well as insurance for people who see the consequences
[22:27:21] <furrywolf> I'm all for letting the stupid people remove themselves from the gene pool. :P
[22:27:34] <SpeedEvil> CaptHindsight: if you don't care about height - you absolutely don't want steel
[22:27:40] <SpeedEvil> aluminium is enormously better
[22:27:57] <SpeedEvil> - for the same weight
[22:28:11] <CaptHindsight> but I want to get a good workout while I'm machining
[22:28:19] <CaptHindsight> maybe lead inserts
[22:29:17] <CaptHindsight> maybe a polycarbonite shell with a layer of sand
[22:29:38] <SpeedEvil> reactive footwear
[22:31:02] <Valen> just get these CaptHindsight http://www.blundstone.com/au/work-safety-boots/smelter-boots/style-971
[22:32:18] <MacGalempsy> os1r1s: lets see some pics of your pcar
[22:32:47] <CaptHindsight> just think of how many childrens toes would be saved if they were required to wear those
[22:33:24] <SpeedEvil> Now I want to know what a pass for 'Dip tested to 960°C in molten aluminium & 1520°C in molten steel' is like
[22:33:56] <MacGalempsy> so guys, I am torn in a decission on the ATC
[22:34:07] <CaptHindsight> 10 second immersion with no pain
[22:34:30] <MacGalempsy> the chucks are too $$$ to buy 20 of them, so I went with the DARKON chucks that are made for the Tormach
[22:35:07] <MacGalempsy> so the question is, do I precission grind the chucks to fit the aluminum tool holders, or do I make new aluminum tool holders to fit the chucks?
[22:35:25] <Wolf_> 20 chucks?
[22:35:48] <CaptHindsight> these are also waterproof http://workingperson.com/black-diamond-boots-mens-0912-x2-leather-steel-toe-kevlar-lined-waterproof-firefighter-boot.html
[22:35:53] <MacGalempsy> yeah, each chuck takes up one slot in the ATC
[22:35:58] <MacGalempsy> and holds a collet
[22:36:19] <Wolf_> so collet holders, not chucks
[22:36:44] <MacGalempsy> they call them chucks from the seller, it doesnt matter much
[22:36:58] <MacGalempsy> so here is how my machine is supposed to look changing https://www.youtube.com/watch?v=_qhZFGOKkEk
[22:37:12] <MacGalempsy> Here is the tormach https://www.youtube.com/watch?v=TGQCrPwWb-U
[22:38:10] <MacGalempsy> the collet holders for my machine were going to be like 200-300 each, but the Darkon ones for the the tormach were only $50 each
[22:38:18] <Tom_itx> anybody here familiar with CATIA?
[22:38:31] <Wolf_> hmm, can you find someone with a cnc to make the tool holder arms? :P
[22:38:55] <Tom_itx> the 'real' question is: is there a contour select tool in CATIA like SOLIDWORKS has for extruding solids from geometry?
[22:39:17] <MacGalempsy> one question I have is that on the benchmanXT each collet holder is indexed in the tool holder before going into the machine and the tormach ones are not. will this make a difference?
[22:40:17] <Wolf_> does the spindle have drive ears/dogs whatever
[22:41:00] <MacGalempsy> the only thing in the spindle is a bolt coming down that lines up with the index position. the bolt is removeable
[22:43:01] <MacGalempsy> I figured a M19 would get the spindle to the right spot. once concern I have is any effect of warpage on the collet holder from grinding it down
[22:43:31] <os1r1s> MacGalempsy: http://gallery.mounicou.com/Cars/Cayman-S/i-4fW6DF8/0/L/_MG_5726-L.jpg
[22:43:44] <MacGalempsy> Very nice
[22:44:08] <furrywolf> got my new led headlamp... the orange peel reflector was supposed to give a flood beam, but it's still way too focused.
[22:44:31] <MacGalempsy> os1r1s: https://www.flickr.com/photos/58181938@N03/8764344525/in/datetaken/
[22:44:56] <os1r1s> MacGalempsy: Very nice 996 turbo?
[22:44:59] <MacGalempsy> with the big turbos. just got a Misha911 tail for it today i nthe mail
[22:45:11] <MacGalempsy> 996tt x50 m110
[22:45:21] <os1r1s> Very cool
[22:45:46] <os1r1s> I have a GT3 throttle body, an Quaiffe TBD, and a software flash on mine.
[22:45:54] <os1r1s> Makes for a blast in a NA car
[22:46:23] <MacGalempsy> very fun. Porschepalooza is coming up next month in Eureka Springs, AR supposed to be 250 pcars
[22:48:41] <os1r1s> That's tempting. Not too far from here
[22:49:05] <MacGalempsy> where are u?
[22:50:44] <os1r1s> MacGalempsy: Near memphis
[22:51:07] <MacGalempsy> im sure the pcca club from there will be coming
[22:51:30] <MacGalempsy> I think the oklahoma chapters and little rock are coming. trying to get my buddy from Dallas to come up
[22:52:19] <PetefromTn_> Heh I just went out there to crank up a Picatinny rail program....looked down and realized I was wearing white socks and no shoes ;)
[22:52:32] <Mac-phone> ha.
[22:54:15] <diginet> has anyone here ever bought one of those chinese linear scales??
[22:54:29] <diginet> http://szhxx.en.alibaba.com/product/630270955-217021536/resolution_1_um_50_3000mm_optical_linear_encoder.html
[22:54:39] <PetefromTn_> yeah I call it a digital caliper ;)
[22:54:56] <diginet> supposedly, those are $65 a pop, for 200mm travel/1 micron but it sounds too good to be true
[22:54:57] <CaptHindsight> PetefromTn_: at least you are comfortable
[22:55:16] <PetefromTn_> Oh certainly I am
[22:55:49] <PetefromTn_> I actually TRY to ensure that the shop floor is REALLY clean of chips because my kids are always running out there to see me and ask me questions etc.
[22:56:13] <Mac-phone> the diy edm uses a harbor freight one for a depth gauge
[22:56:24] <CaptHindsight> diginet: yeah, you might get lucky and get a working one
[22:56:57] <CaptHindsight> most likely at least accurate to 10um
[22:57:01] <furrywolf> my living room floor has a pile of chips.
[22:57:22] <Wolf_> i’ve tracked chips all over the place here..
[22:57:32] <Mac-phone> how about a used mitutoyo? $50 all day long
[22:57:45] <PetefromTn_> we have laminate flooring in the house so It is just sweep it up LOL
[22:58:15] <PetefromTn_> speaking of which rumor has it the OAK is out and we are going Walnut here soon GOD I HATE DOING FLOORING WORK!!
[22:58:23] <furrywolf> sweeping involves moving enough crap around to have a space wide enough for a broom.
[22:58:27] <Mac-phone> tool changes THEN shoe changes
[22:58:47] <Wolf_> 3000mm mitutoyo?
[22:58:55] <furrywolf> repair the current flooring instead of replace?
[23:00:01] <CaptHindsight> archivist: http://www.theguardian.com/science/2015/apr/19/clockmaker-john-harrison-vindicated-250-years-absurd-claims
[23:00:40] <PetefromTn_> Oh there is nothing wrong with the current flooring hehe
[23:01:01] <PetefromTn_> I recently installed the walnut flooring in my daughter's house
[23:01:03] <Wolf_> diginet: its a glass scale so should be doable… I think
[23:01:10] <PetefromTn_> and now she has decided she likes it better
[23:03:32] <furrywolf> ... replacing good flooring is wasteful, of both time and money.
[23:03:38] <Wolf_> oh, Mac-phone, thx I knew I saw TTS type holders somewhere, just forgot the name lol
[23:03:40] <CaptHindsight> chip and epoxy flooring
[23:03:50] <CaptHindsight> then you don't have to sweep
[23:04:23] <Wolf_> I’m planning on using the almost cheapest engineered wood flooring I can find in most of my house
[23:05:02] <CaptHindsight> mdf and contact paper
[23:05:32] <Wolf_> lol, noticed I said almost< cheapest…
[23:06:14] <diginet> Wolf_: what do you mean by doable? as in, "might not catch on fire" or "might actually meet given specs"
[23:06:26] <Wolf_> both
[23:06:26] <PetefromTn_> when we first bought our home it needed floors bad downstairs and we also had other repairs and improvements we needed to make so we bought some relatively inexpensive laminate flooring
[23:06:43] <PetefromTn_> it has actually lasted quite well and looks reasonably good almost 9 years later
[23:07:05] <diginet> hmmm
[23:07:12] <PetefromTn_> but I must admit that after seeing the walnut in my daughters house it looked really nice and it would go well in our homes decor
[23:07:16] * diginet is debating on whether to gamble on these
[23:07:16] <CaptHindsight> I prefer either concrete or distressed wood floors
[23:07:40] <PetefromTn_> I like concrete dyed and polished floors that is a neat media
[23:07:45] <Wolf_> I was going to do concrete floor in my kitchen
[23:07:49] <CaptHindsight> I currently have all concrete
[23:08:03] <Wolf_> but… don’t know how to stain it, or finish it
[23:08:11] <PetefromTn_> our home is not on a slab so we have wood subfloors
[23:08:31] <CaptHindsight> the shop floor is sealed with a silicate and it's so smooth I can slide machines around
[23:08:34] <Wolf_> would work great with underfloor hydronic heat tho
[23:08:43] <diginet> also, does "travel length" mean the distance that it measures?
[23:09:04] <Wolf_> one would hope so diginet
[23:09:14] <CaptHindsight> diginet: hope so, but translations are not always accurate
[23:09:25] <diginet> CaptHindsight: yeah...it's a little bit ambiguous
[23:09:26] <CaptHindsight> or honest
[23:09:27] <Wolf_> ask for a print/cad of the scale
[23:09:33] <diginet> Wolf_: good idea
[23:11:53] <PetefromTn_> Still gotta order a ballscrew for the lathe here
[23:12:18] <PetefromTn_> was going to order from Chai on ebay but wondering if there is a better reasonable priced option
[23:13:13] <Wolf_> other then equipment pulls or surplus, not really...
[23:13:42] <Wolf_> I ended up spending extra on my ballscrews to get US ship tho =/
[23:15:50] <diginet> I'm trying to build my own linear motor, lol
[23:15:56] <diginet> insanity...perhaps
[23:16:11] <PetefromTn_> yup
[23:16:14] <Wolf_> maybe...
[23:16:32] <diginet> it's not so bad really. They're somewhat simple, and I don't need anything too high-powered
[23:16:34] <Tom_itx> no cad experts here ehh?
[23:16:40] <diginet> the most difficult part is sourcing the coils
[23:16:55] * Wolf_ can’t say much about the insanity part, I just ordered a sewing machine motor to spin my mill spindle
[23:17:05] <PetefromTn_> I am a complete Expert on......well....basically nothing
[23:17:06] <furrywolf> I still haven't found any working cad software to become an expert at.
[23:17:13] <CaptHindsight> diginet: why not use forcers from ebay?
[23:17:18] <Tom_itx> Wolf_, did you figure a way to hack the speed and direction?
[23:17:21] <diginet> CaptHindsight: too expensive
[23:17:36] <Wolf_> nope, but I will soon lmao
[23:17:37] <CaptHindsight> $50-$100?
[23:17:40] <diginet> CaptHindsight: plus, I don't need anything super high powered, I'm build a positioning stage, no a mill
[23:17:51] <diginet> CaptHindsight: try finding a linear motor for that :P
[23:17:59] <CaptHindsight> I do all the time
[23:18:03] <Tom_itx> PetefromTn_, i found a cool way to extrude multiple features in solidworks but would like to do the same thing in catia
[23:18:31] <diginet> CaptHindsight: working ones??
[23:18:35] <PetefromTn_> I extrude featuers all the time in solidworks just click away LOL
[23:18:47] <Tom_itx> is there a contour select tool in CATIA like SOLIDWORKS has for extruding solids from geometry?
[23:18:55] <Tom_itx> was the earlier question
[23:19:01] <Wolf_> Tom_itx: got this on order http://www.aliexpress.com/item/Energy-Saving-Brushless-Servo-Motor-for-industrial-Sewing-Machine-TS750-1-750W-110V/1776878320.html when it gets here I’ll toss the scope on it
[23:19:13] <diginet> CaptHindsight: a linear motor, not a stepper/servo + ballscrew
[23:20:02] <CaptHindsight> http://www.ebay.com/itm/Aerotech-BLMFS5-142-A-72-7-157-2lb-Steel-Core-Forcer-Coil-Flat-Linear-Motor-/131615113575
[23:20:13] <CaptHindsight> I know, I build them all the time
[23:20:15] <PetefromTn_> No idea can't afford Catia....hell can't afford solidworks LOL.... that is why the only experience I have with it was at the shop I worked in
[23:20:41] <diginet> CaptHindsight: hmm...interesting
[23:20:47] <Tom_itx> i found a 'Multi-Pad Definition' toolbar... maybe that's it
[23:20:52] <Tom_itx> i
[23:20:59] <Tom_itx> i'll try it tomorrow
[23:21:06] <diginet> CaptHindsight: but what about the magnet track? or do you build those yourself?
[23:21:16] <diginet> also, I wanted to play with a tubular design...more compact
[23:21:24] <CaptHindsight> http://www.ebay.com/itm/YASKAWA-Coreless-Linear-Servo-Motor-SGLGM-30216A-/331653045365
[23:21:39] <CaptHindsight> magnet track^^
[23:22:00] <diginet> CaptHindsight: you're good!
[23:22:00] <Tom_L> https://catiamaster.wordpress.com/2012/01/15/3-2-reference-elements-sketch-based-features/
[23:22:13] <Tom_itx> PetefromTn_, near the bottom of that describes the tool
[23:23:11] <Wolf_> http://www.aliexpress.com/store/product/TR-8CB-CIRCUIT-BOARD-W-6-SCREWS-for-TR600-sewing-machine-motor/1088544_1786414158.html looks hackable :D
[23:23:16] <diginet> CaptHindsight: only problem is that I don't know the temp rating on the magnets in the track...I need what high temp neo magnets (the ~150 C max op temp ones)
[23:23:18] <CaptHindsight> forcer and track http://www.ebay.com/itm/Trilogy-Magnetic-Rail-Assembly-Linear-Servo-Motor-w-2x-7-Magnetic-Tracks-/121382811128
[23:24:37] <PetefromTn_> Tom_itx I better not read that or else I will feel the STING of poverty in my inability to afford such grandiose softwares
[23:24:52] <diginet> CaptHindsight: now can you find me a set of scales for that cheap? :P
[23:24:54] <Tom_itx> i'm just trying to figure it out
[23:24:57] <CaptHindsight> diginet: it's the coil/forcer that gets hot, not the magnets
[23:25:01] <Tom_itx> compared to solidworks
[23:25:05] <Tom_itx> it's quite similar
[23:25:26] <Tom_itx> oh, i can't afford it either btw
[23:25:33] <Tom_itx> using a free student copy
[23:25:37] <diginet> CaptHindsight: no, I know. The application I'm wanting this for would be heated to around ~80c
[23:25:51] <Tom_itx> it's free to learn
[23:25:57] <Tom_itx> and you can't take that from me :)
[23:26:10] <PetefromTn_> heh nope
[23:29:58] <CaptHindsight> Catia is pretty nice
[23:30:07] <diginet> what's that?
[23:30:13] <CaptHindsight> almost as nice as NX
[23:31:09] <CaptHindsight> Tom had some scales on ebay for a low price
[23:31:20] <furrywolf> I HATE INSURANCE COMPANIES.
[23:31:31] <furrywolf> Just got their offer for the total loss of my car... $500.
[23:31:45] <furrywolf> So now I have to have my lawyer handle that too.
[23:31:46] <furrywolf> grrrrr.
[23:31:59] <CaptHindsight> yup, blue book value
[23:32:29] <furrywolf> more like bullshit value... comparable cars sell on ebay for $2500-$7500.
[23:32:39] <furrywolf> last one sold for $5000, and it was only 2wd.
[23:33:54] <furrywolf> I have over $2000 into it plus several hundred hours of labor.
[23:34:20] <CaptHindsight> sure, thats why you document it all or they don't care
[23:35:02] <furrywolf> Amazingly, when I was working on my car, I wasn't planning on filing an insurance claim on it.
[23:35:05] <CaptHindsight> take pics of the restoration and keep all the receipts
[23:35:29] <CaptHindsight> yeah, but that's how they work, nice isn't it
[23:35:56] <CaptHindsight> you find out when you get screwed over after you paid all the premiums
[23:41:21] <furrywolf> I have receipts for most of the parts, but that doesn't include the labor to install them. For example, I replaced the cruise control stalk and switch... and you have to take apart a bunch of the steering column to get the stalk out and run the wires.
[23:41:49] <furrywolf> $50 part (purchased online from a specialty dealer, new-old-stock), $300 in labor if I were paying someone to do it.
[23:43:19] <furrywolf> or more if they're not competent in working on old cars.
[23:45:44] <CaptHindsight> I rebuilt my engine for $1k in parts and spent 2 weeks, whats that about $10K?
[23:46:04] <furrywolf> yep
[23:48:44] <CaptHindsight> it's unusual so they don't factor that in
[23:49:24] <CaptHindsight> most people don't get 500k-1M miles from their car over 30 years
[23:51:19] <furrywolf> bbl, wolfy bedtime
