[07:11:20] <fran_becu_> hi! i want to build linuxCNC on ubuntu 14. it is possible?
[07:15:18] <jthornton> why ubuntu 14?
[07:29:12] <jdh> because numerologists have confirmed that 14 is a good number for cnc
[07:29:23] <jthornton> lol
[07:33:07] <Loetmichel> *ha!* it fits like a glove!... but that keyboard is VERY expensinve now... the CNC had taken the better part of 5 hours to mill that aluminium part... ;-)) ->

[07:36:25] * SpeedEvil wonders how to make an entirely optical keyboard cheap
[07:36:41] <SpeedEvil> (apart from a small electronics module with one USB wire to it)
[07:37:11] <malcom2073> SpeedEvil: like beam breaking?
[07:37:18] <SpeedEvil> yes
[07:37:33] <malcom2073> Or this:

[07:37:34] * SpeedEvil wonders about a partially routed PCB, with fibres pressed in
[07:37:42] <SpeedEvil> Those are crap
[07:37:49] <malcom2073> I'd imagine so heh
[07:37:53] <SpeedEvil> no crapper feel than touchscreens of course
[07:37:58] <malcom2073> I can't see how they're easy to use for anything but hunt and peck
[07:38:09] <malcom2073> s/easy/good
[07:39:17] <malcom2073> What about using color? Each key has its own light color, and detect the incoming color as a combonation of colors? Like a resistance based keypad, but optical
[07:39:45] <SpeedEvil> malcom2073: you can
[07:39:54] <SpeedEvil> malcom2073: for example - I can hit ~30wpm on a nexus 7
[07:39:57] <SpeedEvil> without looking
[07:40:07] <malcom2073> Oh I enjoy touchscreen keyboards
[07:40:19] <malcom2073> not as much as a normal one, but they're not bad to use if it's a decent screen
[07:40:21] <SpeedEvil> but - I can hit 40wpm on my n900 - with an actual hardware keyboard and 100% confidence that what I've typed is real, not garbage
[07:40:51] <SpeedEvil> to the point I'd type paragraphs while doing other things
[08:28:25] <fran_becu_> because i have ubuntu 14 in my laptop. i want to use linuxcnc with my desk mill
[08:30:00] <jdh> linuxcnc does not generally play nicely with laptops
[08:33:37] <fran_becu_> i play it from the live CD with good result
[08:33:44] <fran_becu_> sorry for my english..
[08:34:56] <pcw_home> linuxcnc runs on ubuntu 14, but for real time you need to install a RT kernel
[08:36:45] <fran_becu_> ok. Then, you recomend me to use install ubuntu 10 on my lap?
[08:36:59] <jdh> linuxcnc does not generally play nicely with laptops
[08:38:40] <pcw_home> I am running linuxcnc on my Ubuntu 14 desktop, its fine but more work than using the latest ISO
[08:40:22] <fran_becu_> how i can install linuxCNC on ubuntu 14. for some tests
[08:40:48] <pcw_home> I built from source
[08:42:50] <fran_becu_> can you give me the link please?
[08:46:50] <pcw_home> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Installing_LinuxCNC#Installing_to_Ubuntu_10_04_or_8_04_from_source
[08:46:51] <pcw_home> is approximately correct for 14.04
[08:48:35] <fran_becu_> Thank you very much!
[08:49:36] <pcw_home> Another option is to install the precise (ubuntu 12.04) package from the buildbot and then update ubuntu to 14.04
[08:50:22] <pcw_home> There will be some glitches, since this is off the beaten path
[10:10:58] <CaptHindsight> there were a few missing dependencies when trying to use the 12.04 packages on 14.04
[10:12:38] <CaptHindsight> it worked but I forgot what was missing

[11:55:57] <ssi> fabric work is pretty fun
[11:57:51] <Rab> ssi, is this a seat for a light airplane?
[11:58:02] <ssi> yeah
[12:09:44] <ssi> randall munroe's been peeking at my life I think
[12:09:46] <ssi> http://what-if.xkcd.com/imgs/a/119/lasers.png
[12:12:39] <jdh> have you considered that it might have been a message from ghod telling you to buy a sailboat?
[12:13:07] <ssi> might have been! :)
[12:13:11] <ssi> it's not off the table
[12:13:19] <jdh> I'll take a lathe, cheap.
[12:14:43] <ssi> it's for sale, cheap
[12:14:44] <ssi> come get it
[12:16:29] <Rab> "those so called german bearings arent made in germany, german is the name of the company in china/japan that makes the bearings."
[12:16:35] <ssi> hahaha
[12:16:41] <Rab> ^^ from a discussion about chinese CNC spindles
[12:16:45] <ssi> I once read an apocryphal story that there's a town in china named "USA"
[12:16:50] <ssi> so they can mark stuff "Made in USA"
[12:18:11] <LeelooMinai> ...
[12:20:17] <_methods> the candidate lol
[12:23:23] <jdh> except it is country of origin, not city.
[12:24:22] <jdh> I heard that in high school about USA, japan

[12:41:58] <CaptHindsight> same for McDonalds beef, it comes from a company called 100% Beef, so obviously there's nothing dishonest about that
[12:42:28] <malcom2073> http://www.snopes.com/business/genius/usa.asp
[12:42:52] <CaptHindsight> truth or rumor?
[12:44:17] <malcom2073> If you have the intelligence to run a company big enough to provide mcdonalds with beef, you likely have the intelligence enough to know that trouble isn't worth the amusement value
[12:44:32] <malcom2073> But hey, some pretty big companies have done some pretty dumb stuff before, so who knows :)
[13:30:46] <Roguish> hey all. how do i add a symlink or something so I can keep all my configs on a usb thumb drive? been looking and cannot figure it out....
[13:34:58] <_methods> ln -s
[13:36:26] <_methods> see man ln
[13:54:14] <yeahsup> hey, I have question about the power supply of the CNC I am currently building. I've got 4 stepper motors (bipolar, 2.8V, 1,7A). Is a 200W 24V powre supply enough? (I calculated 2phases * 2.8V * 1,7A ~ 10W per motor, with some loss in the driver at worst 20W => 80W total). is my calculation correct?
[13:58:42] <cradek> do your drives limit you to 24v?
[13:59:06] <cradek> I don't know the answer to how much power is enough, but I know you absolutely want as much voltage as possible
[14:12:26] <renesis> feedback is useless without power headroom
[14:13:00] <renesis> well, thats not true i guess least you have fault awareness without the headroom to correct error
[14:47:49] <SpeedEvil> yeahsup: if you actually run 2.8V steppers at 2.8V, you will get very, very slow speeds.
[14:48:11] <SpeedEvil> They typically are run at 1.7A - constant current - from a drive that can do higher voltage
[14:48:28] <yeahsup> sorry for the late response, I've got those motors
http://shop.myhobby-cnc.de/media/pdf/nema17.pdf
[14:48:31] <yeahsup> last one in the list
[14:48:45] <SpeedEvil> if you run them at 28, not 2.8V - current limited to 1.7A - you get 10* theRPM, and the same torque
[14:48:49] <yeahsup> my power supply is a meanwell 200W 24
[14:48:50] <yeahsup> V
[14:49:12] <yeahsup> using big easy drivers
[14:49:27] <SpeedEvil> not familiar with those
[14:50:27] <yeahsup> can take 2,0A per phase and upto 30V
[14:51:38] <yeahsup> so I guess my driver gets 24V and transforms this to 1,7A (whatever current I adjust it to) and the motor takes its 2,8V?
[14:53:58] <ssi> it doesn't transform anything
[14:54:14] <ssi> the coils are inductive, so it takes time to saturate them
[14:54:20] <ssi> the more voltage, the quicker they saturate
[14:55:56] <renesis> motors are magnetic, so their force is proportional to current through them, not voltage across them
[14:56:28] <renesis> so if you want lots of current through a coil quickly, you need lots of voltage
[14:58:14] <yeahsup> hm =/ soooo I still don't get it. 24V/200W power supply, 4 of those motors from the spec set to 1,7A. will this work?
[14:58:47] <renesis> not enough information
[14:59:05] <yeahsup> what is missing?
[14:59:37] <renesis> inductance and resistance of the motor coil i guess
[15:00:43] <renesis> anyway, the driver prob wont regulate the voltage to a lower voltage, its going to chop up the voltage and look at the current
[15:01:24] <yeahsup> according to the spec its 2.8 mH (whatever unit this is) inductance, and 1.65 Ohm / Phase resistance
[15:02:03] <renesis> millihenries
[15:02:53] <renesis> so now you prob want to look in the manual for your driver
[15:03:11] <ssi> 2.8mH wants around 50V iirc
[15:03:13] <renesis> and see what it recommends
[15:03:57] <Tom_itx> sounds about right
[15:03:59] <ssi> 1000 * sqrt(0.0028H)
[15:04:02] <ssi> = 53V
[15:04:30] <Tom_itx> what happens if you exceed that?
[15:04:44] <bnmorgan> you may let the magic smoke out.
[15:04:52] <Tom_itx> maintaining constant current...
[15:05:04] <ssi> I think that's just the voltage where anything higher is diminishing returns
[15:05:20] <ssi> that's the "coil saturates fast enough" voltage
[15:05:21] <Tom_itx> kinda what i thought
[15:05:30] <Tom_itx> yeah
[15:05:42] <ssi> and i think above that voltage you'll get excessive heating
[15:05:53] <Tom_itx> probably
[15:06:02] <Tom_itx> mine run very cool for steppers
[15:06:21] <Shaun413> hi
[15:06:28] <Tom_itx> but i don't have em cranked up all the way either
[15:07:44] <yeahsup> is there any formula I can plug in my numbers to get a matching power supply? (sorry for being too dumb somehow -.- )
[15:08:01] <ssi> yeahsup: I gave it to you above
[15:08:05] <Tom_itx> sure
[15:08:07] <ssi> 53V is the magic number
[15:08:13] <renesis> there are usuallt formulas in the driver manuals, i think there is a general formula on the linuxcnc wiki
[15:08:16] <ssi> but your drivers max at 30V
[15:08:19] <ssi> so 30V is a winner
[15:08:51] <jdh> or maybe 28v
[15:08:59] <ssi> yeah perhaps
[15:09:03] <renesis> what is the 1000 number?
[15:09:07] <ssi> if you have a 24V supply, run them at 24V
[15:09:26] <ssi> it's a magic number
[15:09:32] <ssi> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Formulas
[15:09:58] <renesis> so its just a fuckton of headroom
[15:09:58] <jdh> I run my 24v switcher at 28v for my old router.
[15:10:16] <yeahsup> actually have to of those lying around and have been using my router with both (1 for 2 motors), but since none of those generates considerable heat, I guess my calculations about 2 years ago were "kind of" wrong
[15:11:00] <renesis> they should be warm, but def pass the spit test
[15:11:31] <renesis> they should be just about the point where you think maybe its not good to keep holding onto them
[15:11:51] <renesis> this is after being on for like an hour
[15:12:24] <renesis> takes a long time for the heat in the coils to saturate the motor
[15:12:50] <yeahsup> well, my motors get somewhat warm, power supplies not at all. and I have been using my router for a couple of projects now. however, this made me think, the power supplies might be a bit oversized
[15:13:06] <renesis> thats usually a good thing
[15:13:21] <renesis> supplies run at max spec
[15:13:41] <renesis> they just have to not burn your house down at a bit over max spec to be legal
[15:14:05] <renesis> er, *supplies run at max spec break
[15:14:14] <renesis> last word is kinda important
[15:19:53] <Tom_itx> seems an awful lot of reference to burning houses lately...
[15:21:01] <ssi> lot of it going around :P
[15:23:54] <yeahsup> thank you all! at least my house shouldn't burn down as long as I keep my hobby mill running as it is =)
[15:24:05] <_methods> heheh
[15:27:08] <renesis> tom_itx: this is one of the few hard rules in audio r&d
[15:27:33] <renesis> cant burn down houses or venues, because its really hard to sell things without a UL tag
[15:28:13] <renesis> note that this rule is not taken literally in the boutique tube amp part of the business
[15:35:14] <_methods> heh state of emergency in missouri
[15:35:20] <_methods> here we go
[15:36:02] <Tom_itx> earthquake or blizzard?
[15:36:08] <_methods> ummm
[15:36:09] <Tom_itx> we've had both lately...
[15:36:19] <_methods> neither?
[15:36:39] <_methods> race riots
[15:36:40] <_methods> lol
[15:36:47] <_methods> the other natural disaster
[15:37:11] <Tom_itx> oh that.
[15:37:17] <Tom_itx> they just want attention
[15:50:09] <renesis> missouri had earthquakes?
[15:50:23] <JT-Shop> yea
[15:50:43] <JT-Shop> New Madrid fault line
[15:53:36] <renesis> oh damn theres been 8s there
[15:58:18] <Rab> renesis, the Mississippi river was reported to have run backwards.
[16:00:17] <renesis> do not believe
[16:01:38] <CaptHindsight> the Mississippi river changed it course, but not backwards
[16:02:02] <Rab> http://www.showme.net/~fkeller/quake/mississippi_river_ran_backward.htm
[16:02:20] <Jymmm> I've been asked to make them decoder discs that "CLICK" into place when rotated. These will be made out of plastic, any thoughts on the mechanics?
[16:02:35] <CaptHindsight> for a short distance
[16:03:00] <SpeedEvil> Jymmm: little holes in the disk, ball bearing pressed into them, grease
[16:03:13] <Jymmm> SpeedEvil: 8yo child
[16:03:18] <SpeedEvil> Jymmm: how reliable does this need to be?
[16:03:25] <SpeedEvil> ?
[16:03:30] <Jymmm> reliable?
[16:03:58] <Jymmm> it needs to have 26 indents
[16:04:14] <Jymmm> A-Z
[16:04:25] <SpeedEvil> is it going to be used for a couple of hours, then put in the cupboard, or daily for 10 years
[16:05:03] <Jymmm> I need to make 4 of them. Thay are part of a story book that has been written.
[16:05:18] <Connor> spring loaded ball.

[16:17:18] <cpresser> did someone here try to communicate with the "huanyang-vfd" via modbus-rtu?
[16:17:48] <cpresser> i have the "hy_vfd" component, which kind of works. but i wanted to write a better onw
[16:18:11] <cpresser> however, when i try to talk to it with pyserial, i dont get any answer at all
[17:26:31] <jthornton> are you being nice to it?
[17:39:25] <Shaun413> no
[17:39:30] <Shaun413> im never nice to IT
[17:42:40] <Tom_itx> Jymmm, ask Fisher Price how to do it
[17:43:57] <Shaun413> to do what
[17:46:44] <Tom_itx> jthornton is your swamp slushy?
[17:47:42] <ssi> the wind is howling throuch here tonight
[17:47:47] <Tom_itx> supposed to be 9 or 10 tonight...
[17:47:58] <ssi> I think we're supposed to be 16
[17:50:32] <Shaun413> 23 here
[17:50:57] <Shaun413> 19 tom, single dig wind chill tho
[17:51:13] <Shaun413> come on, it was 5o today!
[17:51:14] <Shaun413> why
[17:51:18] <Shaun413> 50*
[17:54:23] <jdh> 77f here
[17:55:34] <Shaun413> where!
[17:55:38] <Shaun413> TAKE ME WITH YOU
[17:55:57] <CaptHindsight> 13F (-11C) here already
[17:57:46] <Tom_itx> another ice age is coming...
[17:59:09] <_methods> no it's not
[17:59:13] <_methods> global warming man
[17:59:16] <_methods> it's getting hotter
[17:59:23] <_methods> can't you tell

[18:45:37] <LeelooMinai> Quite an achivement to have wikipedia entry like that
[18:45:46] <_methods> yeah he's quite special
[18:46:04] <PetefromTn_> it's nauseating that he is given such notariety
[18:47:04] <_methods> i'm sure he made his wiki entry himself
[18:47:43] <shaun413> wait
[18:47:52] <shaun413> why would he make a wiki????
[18:48:15] <_methods> Jymmm: you wanna swing that banhammer again lol
[18:48:38] <shaun413> ...
[18:48:45] <Jymmm> _methods: You asking me to ban you?
[18:48:51] <_methods> heheh
[18:48:52] <_methods> no
[18:48:55] <Jymmm> Ok, since you asked...
[18:48:58] <PetefromTn_> is that what that Chanserv mode change means?
[18:49:00] <CaptHindsight> oh you kids today with your intertubes, trolls and rap music
[18:49:22] * Jymmm sets mode: +dumbass _methods*!*@*
[18:49:30] <_methods> hahah
[18:49:34] <_methods> that was already enabled
[18:49:42] <Jymmm> lol
[18:49:52] <zeeshan> you guys didnt like the story?
[18:49:55] <zeeshan> i thought it was interesting
[18:50:04] <zeeshan> its how a mach 3 user thinks
[18:50:07] <zeeshan> :D
[18:50:31] <Jymmm> Should these leak between the brass and compression parts?

[18:50:55] <Jymmm> The threads are 90% engaged to the fitting. Defect?
[18:51:19] <LeelooMinai> I wanted to ask something, but now forgot
[18:51:22] <Jymmm> err I meant crimped not compression
[18:51:25] * LeelooMinai thinks
[18:51:36] <Jymmm> LeelooMinai: goto the room you last thought it
[18:51:44] <shaun413> hm
[18:52:09] <Jymmm> LeelooMinai: goto the room you last thought the question that is.
[18:52:29] <LeelooMinai> I know - is there some tool for cutting machine screws so that they still work nicely? Like bolt-cutter, but non-thread destructive. If I need I do that with a hacksaw and vise, but seems a bit lame way to do that:)
[18:52:50] <_methods> angle grinder with cutoff wheel
[18:52:51] <CaptHindsight> Jymmm: nope
[18:52:55] <_methods> or a lathe
[18:53:00] <Jymmm> LeelooMinai: Thread two nuts on it before cutting.
[18:53:09] <zeeshan> LeelooMinai: meet me!
[18:53:13] <zeeshan> im going to kitchener
[18:53:16] <zeeshan> in 5 mins
[18:53:22] <zeeshan> :D
[18:53:31] <LeelooMinai> zeeshan: I don't live in Kitchener...
[18:53:34] <Jymmm> CaptHindsight: no on leaking, or no on being defective?
[18:53:35] <zeeshan> whoops :p
[18:53:43] <LeelooMinai> O wait, I do
[18:53:45] <zeeshan> im going there to pick up some tires
[18:53:53] <zeeshan> im kidding about meeting
[18:53:57] <LeelooMinai> But I could live on Antarctica and it would be the same - if I had internet that is
[18:53:57] <zeeshan> you dont wanna meet me
[18:53:59] <zeeshan> im mean
[18:53:59] <Jymmm> no your not
[18:54:01] <CaptHindsight> Jymmm: they should be leaking from that
[18:54:15] <CaptHindsight> Jymmm: should not be, sorry
[18:54:28] <Jymmm> CaptHindsight: ok, so more than liely a defective hose?
[18:54:44] <LeelooMinai> Angle grinder kind of makes me nervous. I used it quite a lot of times, but if I can I would rather avoid it:)
[18:54:58] <CaptHindsight> Jymmm: maybe or a bad crimp
[18:54:59] <Jymmm> LeelooMinai: hacksaw, dremel
[18:55:09] <LeelooMinai> Right, so hacksaw is the best I guess.
[18:55:10] <Jymmm> CaptHindsight: Ok, thanks. these are pre-made home depot.
[18:55:16] <_methods> only ways i know are lathe, grinder, dremel, or hacksaw
[18:55:16] <PetefromTn_> die grinder with ziss cutoff wheel and a couple nuts
[18:55:34] <_methods> or bench grinder
[18:55:40] <zeeshan> LeelooMinai: any good food places in kitchener?
[18:55:48] <zeeshan> gf is comin with me too
[18:55:51] <zeeshan> i take her for a treat
[18:55:51] <_methods> grab the bole with some vise grips and grind away
[18:56:05] <_methods> s/bole/bolt
[18:56:06] <LeelooMinai> zeeshan: I don't leave my house almost ever - so no idea:)
[18:56:50] <PetefromTn_> LOL yeah because she.......is WEEV!!
[18:57:00] <LeelooMinai> I guess dremel + one of those ceramic little disks would do the job too
[18:57:37] <PetefromTn_> I hate those damn things... they break and explode at the blink of an eye
[18:57:38] <CaptHindsight> Jymmm:
http://ibin.co/1hbjOgxlRckr is this where it leaking from?
[18:57:54] <shaun413> anyone know how to clean up metal on old tools?
[18:58:01] <LeelooMinai> Yes, or you leave the rotary tool with them attached, step on it and boom - no disk
[18:58:04] <shaun413> I have some miller falls stuff
[18:58:09] <shaun413> I want to refurb
[18:58:17] <shaun413> rust stains galore
[18:58:28] <PetefromTn_> get the abrasive fiber disks they are better and cut faster
[18:58:43] <_methods> electrolysis
[18:58:48] <CaptHindsight> https://www.youtube.com/watch?v=y4yYF8gSHdA Rust removal by Electrolysis
[18:58:50] <LeelooMinai> I have whole box of cutting disks for angle grinder
[18:58:52] <shaun413> hmm really?
[18:58:59] <shaun413> what kindof battery?
[18:59:05] <LeelooMinai> But angle grinder is a tool of death and destruction
[18:59:15] <PetefromTn_> http://blueroofdesigns.files.wordpress.com/2009/07/dremel-fiberglass-cutting-wheel.jpg
[18:59:20] <_methods> angle grinder should be renamed to skill grinder
[18:59:23] <_methods> much like skill saw
[18:59:37] <PetefromTn_> maybe try clamping your angle grinder with disk in a vise with some leather jaws?
[18:59:48] <LeelooMinai> Also:
https://www.youtube.com/watch?v=_PgkDp0E1io
[19:00:24] <PetefromTn_> what an azzhole..
[19:00:24] <zeeshan> LeelooMinai: why dont you leave your house
[19:00:24] <shaun413> what if its got wood on it?
[19:00:27] <LeelooMinai> Free hair cut:)
[19:00:28] <shaun413> cant electrolisis that
[19:01:24] <zeeshan> today i had an explosion on the bill
[19:01:26] <zeeshan> *mill
[19:01:31] <CaptHindsight> cnc machine of the day
https://www.buildyourcnc.com/jacobr.aspx
[19:01:32] <LeelooMinai> both? :)
[19:01:33] <zeeshan> one of the students
[19:02:00] <zeeshan> crashed a 3/4" end mill at 50 ipm along its full length
[19:02:02] <zeeshan> into the vise
[19:02:10] <_methods> sweet jesus is that a cardboard box on his z
[19:02:27] <_methods> oh nm it's just behind his cnc
[19:02:30] <PetefromTn_> where do you find these monstrosities?
[19:02:34] <zeeshan> that one
[19:02:38] <zeeshan> is a lot better than yesterdays
[19:02:38] <zeeshan> haha
[19:02:50] <LeelooMinai> Yesterday was dried bubble-gum style
[19:03:02] <_methods> you can tell he uses it alot by all the wear on the table
[19:03:32] <LeelooMinai> What is that metal wheel with holes there for?
[19:03:50] <shaun413> elecrolysis wont damage the metal?
[19:03:55] <CaptHindsight> oh no!
https://www.buildyourcnc.com/Item/cnc-machine-blacktooth-laser-cutter-engraver-40w#prettyPhoto
[19:03:55] <_methods> is that a computerless cnc router
[19:03:59] <LeelooMinai> Rotary encoder? P:)
[19:04:01] <_methods> i think he's missing the cnc part
[19:04:05] <_methods> it's just a router
[19:04:13] <CaptHindsight> laser cutter with wooden enclosure and frame
[19:04:21] <zeeshan> http://cdn.instructables.com/FIY/545C/GUS75B8D/FIY545CGUS75B8D.MEDIUM.jpg
[19:04:22] <zeeshan> ROFL
[19:04:25] <_methods> it's a wireless cnc router
[19:04:28] <zeeshan> i love these drawer slide cncs
[19:04:37] <LeelooMinai> Drawer slides!
[19:04:55] <CaptHindsight> features sturdy 2x4 framing
[19:05:04] <_methods> that won't catch on fire
[19:05:07] <zeeshan> wow
[19:05:10] <zeeshan> this is the most ghetto metal one
[19:05:11] <zeeshan> http://henriksplace.se/cnc/cnc_photos/pcbdrillold.jpg
[19:05:12] <zeeshan> rofl
[19:05:20] <_methods> is that the pipe guy?
[19:05:21] <zeeshan> does anyone else see a problem with that one
[19:05:22] <zeeshan> LOL
[19:05:35] <PetefromTn_> priceless an MDF laser CNC machine...
[19:06:16] <_methods> my favorite is still the pipe cnc guy
[19:06:30] <zeeshan> http://cdn.instructables.com/FFX/1MAM/F54HJ7SI/FFX1MAMF54HJ7SI.LARGE.jpg
[19:06:32] <zeeshan> this guy?
[19:06:50] <LeelooMinai> Well, at least pipe will not change shape with humidity
[19:06:52] <_methods> i kept waiting for sean connery and the other league of extraordinary gentlemen to show up
[19:07:28] <LeelooMinai> It looks ridiculous, but I think I would rather have frame from those pipes than wood:)
[19:07:42] <_methods> no the real pipe guy
[19:08:12] <_methods> https://www.youtube.com/watch?v=8PSG2al1Sus
[19:08:14] <_methods> that one
[19:08:38] <shaun413> what can I use for power in electrolysis?
[19:08:43] <_methods> i don't know where CaptHindsight finds these guys
[19:08:52] <LeelooMinai> "it's going to be 3d printer" ...
[19:08:57] <_methods> humans attached to a matrix
[19:09:04] <shaun413> ll
[19:09:04] <_methods> they can power your electrolysis
[19:09:05] <CaptHindsight> pipe guy made this as well
https://www.youtube.com/watch?v=0nGL8S4CmZs&list=UUXgE1q8JCCK7KbdDl4INrbA
[19:09:05] <shaun413> lol
[19:09:10] <shaun413> be srs
[19:09:13] <PetefromTn_> https://www.youtube.com/watch?v=v0KWimmYCzY The only CNC router homebuilt worth building....
[19:09:54] <_methods> peg board bed
[19:09:58] <_methods> why didn't i think of that
[19:10:09] <_methods> i'm suprised the 3dprintards haven't moved to that
[19:10:24] <LeelooMinai> It would be fun if after those closups of it engraving, the camera would zoom out and it would be a guy doing it by hand.
[19:11:18] <shaun413> _methods, why would we?
[19:11:21] <shaun413> peg board?
[19:11:23] <shaun413> what for
[19:12:23] <zeeshan> i like how we're calling hi mthe pipe guy
[19:12:24] <zeeshan> hahaha
[19:12:35] <_methods> he is the pipe guy
[19:12:35] <zeeshan> guy is serious business
[19:12:45] <Tom_itx> Jymmm's a little rusty with the ops
[19:12:55] <CaptHindsight> https://www.youtube.com/watch?v=nh4U4Bam-8s designed using SolidWorks
[19:13:05] <_methods> he was ready to ban me pretty quick lol
[19:13:18] <CaptHindsight> http://cockrum.net/cnc_mechanical.html
[19:13:35] <LeelooMinai> Hmm, those air cooling attachments - are they much less effective that liquid cooling setups? At what point one would need liquid cooling?
[19:13:53] <LeelooMinai> I mean cutter cooling, not spindle
[19:14:04] <shaun413> so..
[19:14:07] <shaun413> electrolysis?
[19:14:20] <PetefromTn_> https://www.youtube.com/watch?v=IGcQ-d2ymz8
[19:14:38] <PetefromTn_> that plywood is actually pretty stout looking...
[19:14:47] <Jymmm> Tom_itx: ?
[19:14:54] <CaptHindsight> shaun413:
http://www.rickswoodshopcreations.com/miscellaneous/rust_removal.htm
[19:15:05] <_methods> LeelooMinai: depends on your spindle rpm
[19:15:16] <_methods> and spindle time
[19:15:17] <shaun413> I want to resotre the toola
[19:15:21] <shaun413> and not damage it
[19:15:43] <CaptHindsight> shaun413: can you save the wood?
[19:15:52] <LeelooMinai> I am asking because liquid versions seems to be major pita... One would need some kind of full enclosure for it.
[19:15:57] <shaun413> its attached with riveted collets
[19:16:02] <shaun413> idk if I can remove them
[19:16:26] <_methods> liquid cooling is superior for sure
[19:16:43] <LeelooMinai> Whereas air cooling seems doable to me - I would just need to run compressor house from the basement to my room:)
[19:16:53] <LeelooMinai> hose*
[19:17:12] <shaun413> so phosphoric acid vs electrolysis?
[19:17:16] <LeelooMinai> And maybe have compressor turn off/on remotely, but that's easy to do.
[19:17:55] <LeelooMinai> But for light aluminum milling, air would do, right?
[19:17:59] <_methods> much easier to have a plastic tub full of water and a pump
[19:18:08] <_methods> right by your machine
[19:18:39] <LeelooMinai> _methods: That does not sounds easier... Sounds like sure way to make terrible mess.
[19:18:59] <shaun413> ^
[19:19:01] <_methods> it's up to you
[19:19:07] <_methods> people do it all the time
[19:19:17] <_methods> probably most people in here use liquid cooling
[19:19:35] <_methods> it's more expensive set up
[19:19:42] <_methods> but you get better performance
[19:19:57] <LeelooMinai> Could be overkill for my purposes
[19:20:00] <CaptHindsight> https://www.youtube.com/watch?v=Gyg9U1YaVk8 Power Tool Drag Racing
[19:20:10] <_methods> you can get a spindle, vfd, and pump package for fairly cheap
[19:20:20] <_methods> still more than an air cooled set up though
[19:20:26] <shaun413> so
[19:20:33] <shaun413> whats less bad for metal
[19:20:37] <shaun413> acid or electrolysis
[19:20:40] <shaun413> for rust remove
[19:20:51] <CaptHindsight> they both remove rust and metal
[19:20:54] <LeelooMinai> Though I plan to enclose top of my machine anyways - in some kind of acrylic or polycarbonate box with light alu frame
[19:21:00] <shaun413> hmm
[19:21:01] <shaun413> ok
[19:21:13] <shaun413> which is cheaper
[19:21:15] <LeelooMinai> So nothing flies off and kills my cat for example
[19:27:21] <LeelooMinai> _methods: That sounds too low for me. Probably would take ages at that current, if you have something that is not tiny.
[19:27:34] <shaun413> its not that badly rusted
[19:27:34] <_methods> yes it takes longer but you can save metal
[19:27:39] <shaun413> I got a lot off already
[19:27:47] <_methods> metal that can be blasted off at higher amps
[19:27:47] <shaun413> just some stains kinda
[19:28:10] <_methods> then use a green scrub pad and some wd-40 you nipplehead
[19:28:20] <shaun413> green scrub?
[19:28:27] <Tom_itx> 3m pad
[19:28:32] <shaun413> heh?
[19:28:59] <Tom_itx> white is finer than green is finer than purple
[19:29:03] <shaun413> like a brillo?
[19:29:12] <shaun413> the blue scrubby thing?
[19:30:16] <Tom_itx> http://www.uline.com/Product/Detail/S-11724/Scouring-Pads-and-Sponges/3M-96-Scouring-Pads?pricode=WY780&gadtype=pla&id=S-11724&gclid=CPPprI38gsICFQmPaQodPKYA5A&gclsrc=aw.ds
[19:30:58] <shaun413> damn thats not cheap
[19:31:01] <shaun413> 20 bucks?
[19:31:18] <Tom_itx> for a boxfull
[19:31:24] <shaun413> oh
[19:31:27] <Tom_itx> http://www.grainger.com/search?gclid=CNuojaL8gsICFYFDMgod10AAtQ&searchQuery=Abrasive+Hand+Pad&cm_mmc=PPC:+Google+Main+4-_-Abrasives%3EHand%20Pads%20And%20Sponges-_-Sanding%20Hand%20Pads%3EAbrasive%20Hand%20Pad%3EBroad-_-Abrasive%20Hand%20Pad&adgrpID=5115315278&kwdID=45530920598&ef_id=VFy5QQAABKswa-dU:20141118011054:s
[19:31:28] <shaun413> is that scotchbrite?
[19:32:40] <Tom_itx> more or less i suppose
[19:32:43] <shaun413> ok
[19:32:48] <shaun413> and that will take rust off?
[19:32:52] <shaun413> or fine stains?
[19:36:53] <CaptHindsight> shaun413: it's an abrasive, it works by removal of the material by rubbing the harder material over the softer material
[19:37:04] <shaun413> ok
[19:37:20] <CaptHindsight> the pads have a mix of polymer and abrasive
[19:37:29] <shaun413> can I put it on a dremel?
[19:37:48] <Tom_itx> not likely
[19:37:51] <shaun413> ok
[19:38:08] <CaptHindsight> there is a bit of common sense and feel involved
[19:38:22] <shaun413> ?
[19:38:24] <Tom_itx> or lack of
[19:39:26] <CaptHindsight> wire brushes (brass and steel) emery cloth, sand paper, scothcbrite pads, pumice (toothpaste) etc etc
[19:39:48] <shaun413> ok
[19:39:50] <shaun413> steel wool?
[19:40:45] <roycroft> there are scotchbrite disks for flexible shaft tools
[19:41:15] <LeelooMinai> shaun413: I would try electrolysis - you will spend a lot of time doing mechanical removal and may scratch the thing too much
[19:41:28] <shaun413> ok..
[19:41:35] <shaun413> can I use a 12v wall wart?
[19:41:45] <roycroft> use a car battery charger
[19:41:45] <Tom_itx> i doubt it
[19:41:45] <LeelooMinai> You can try, but imho it will be slow
[19:41:54] <shaun413> i dont have a battery carger
[19:42:00] <roycroft> get one
[19:42:10] <shaun413> i wanted to avoid buying anything..
[19:42:11] <roycroft> you can find them inexpensively at harbor freight
[19:42:18] <roycroft> you can use your car battery
[19:42:27] <LeelooMinai> shaun413: You are buying time:)
[19:42:39] <roycroft> a 12v wall wart will take about a year
[19:42:48] <roycroft> and that might not be much of an exaggeration
[19:42:55] <shaun413> lol
[19:43:02] <shaun413> its not bad and tiny parts
[19:43:03] <Tom_itx> i doubt the wallwart is rectified good enough to work
[19:43:11] <roycroft> probably not
[19:43:12] <Tom_itx> probably half wave at best
[19:43:16] <roycroft> but that's easy to fix
[19:43:22] <_methods> old pc power supply
[19:43:26] <roycroft> i would get a car battery charger
[19:43:28] <shaun413> i have that
[19:43:32] <shaun413> atx
[19:43:54] <LeelooMinai> shaun413: Maybe you have old car battery? :)
[19:43:54] <shaun413> nope
[19:43:55] <_methods> old atx will work
[19:43:55] <roycroft> assuming you own an automobile it's something you should have anyway
[19:43:55] <shaun413> to the 12v?
[19:43:57] <_methods> yep
[19:43:57] <_methods> 12v
[19:44:02] <shaun413> hmm
[19:44:05] <_methods> make sure you do it in a well ventilated area
[19:44:10] <shaun413> garage?
[19:44:20] <_methods> on 2nd thought do it in an enclosed space smoking cigars for me
[19:44:27] <shaun413> ..
[19:45:12] <roycroft> do not use stainless steel as the anode
[19:45:15] <_methods> personally i'd do it outside on a gfci outlet
[19:45:33] <shaun413> its raining
[19:46:39] <CaptHindsight> no smoking and don't pop the bubbles with a flame or lit cig
[19:46:47] <_methods> ehhe
[19:46:51] * roycroft removes rust in his garage, but places the electrolysis bucket inside a big plastic tub
[19:46:55] <CaptHindsight> as tempting as it might be
[19:46:56] <_methods> especially with an angle grinder
[19:47:06] <shaun413> aww why not
[19:47:34] <Tom_itx> what is this thing you're restoring?
[19:47:34] <_methods> don't shoot angle grinder sparks at the bucket
[19:47:34] <roycroft> feel free to light up the bong while you're staring at the beautiful derusting operationg
[19:47:34] <CaptHindsight> if you do, be sure to record a video
[19:47:34] <LeelooMinai> Because explosiv gases and minor problems like that
[19:47:46] <shaun413> miller falls hand drill
[19:47:48] <Tom_itx> show us
[19:47:57] <shaun413> erg
[19:48:00] <roycroft> pics or it doesn't exist!
[19:48:00] <shaun413> like a rela pic?
[19:48:00] <_methods> bit and brace?
[19:48:02] <shaun413> real
[19:48:17] <Tom_itx> is it worth 2-3 days discussion about it?
[19:48:19] <roycroft> you need before and after pictures anyway
[19:48:32] <_methods> he still has weeks more of questiosn what are you talkin about
[19:48:32] <shaun413> well I already scrubberd some rust off
[19:48:45] <roycroft> anything is worht a 2-3 day discussion, as long as people discuss it for that long

[19:49:00] <shaun413> hot damn
[19:49:13] <shaun413> oh no
[19:49:34] <roycroft> you're supposed to take the before pictures before you take the after pictures
[19:49:41] <shaun413> not mine
[19:49:49] <roycroft> now you have to go leave it out in the mud for a year and start over
[19:50:00] <shaun413> thats not my pic
[19:50:18] <Tom_itx> but you just posted it!
[19:50:21] <CaptHindsight> spray it with some bleach
[19:50:27] <shaun413> its the same drill
[19:50:46] <Tom_itx> i had one of those once
[19:51:21] <_methods> when you're tanaka dies that's all you got lol
[19:51:44] <roycroft> they come in handy other times as well
[19:52:24] <_methods> one handed
[19:52:42] <shaun413> ..
[19:52:59] <shaun413> want me to take a real pic?
[19:52:59] <_methods> drill through a telephone pole with a bit and brace with one hand
[19:53:01] <roycroft> you can drill holes with a spoon bit that are almost impossible with any other setup
[19:54:01] <_methods> http://www.arkansas-ope.com/TANAKA_TED-262L.jpg
[19:54:18] <_methods> hehe bit and brace upgrade
