[03:02:28] <rootB> Hi linuxCnc
[03:02:57] <rootB> I got a CNC-based spindle issue
[03:26:05] <archivist> which is?
[03:46:49] <sivu> the suspense is killing me
[03:47:02] <Deejay> moin
[03:47:05] * archivist died
[03:47:19] <Deejay> RIP
[04:02:00] <Mr_Mayhem> lol
[04:06:53] <toastydeath> I'm really sad there aren't cheaper centerless grinders
[04:07:04] <toastydeath> seems like no matter what size grinder you want to buy they're all about 15k usd
[04:07:26] <toastydeath> would be nice to be able to make pins quickly
[04:10:26] <toastydeath> I get the sense from operators that you can set them up pretty quick for simple shit like that, so it should be competitive with making an accurate pin on a lathe
[05:57:53] <rootB> ???
[06:09:22] <archivist> rootB, we are still in suspenders waiting for any questions
[06:17:52] <jthornton> lol
[06:53:27] <archivist> by the magic of irc I feel a 3d printer problem in my crystal ball
[06:58:20] * skunkworks doesn't know what is going on..
[07:11:27] <Tom_itx> s/spindle/suspense
[07:13:13] <rootB> ok
[07:13:19] <rootB> I busted the acrylic jigsaw of my 3D Printer...
[07:13:23] <rootB> i dont know what to do.
[07:13:27] <rootB> i can't print another jigsaw..
[07:13:32] <rootB> i was thinking on using shapeways
[07:15:08] <Tom_itx> well think on it for a few hours and let us know how it ends
[07:15:15] <rootB> However, i have another problem..
[07:15:18] <rootB> I own a shapeoko you se..
[07:15:24] <rootB> I think you are familiar with the shapeoko..
[07:15:28] <rootB> And im trying to upgrade it
[07:15:46] <rootB> Since the Driver it uses is basicalyl an arduino hooked up to a grbl shield
[07:17:00] * Tom_itx doesn't see anything lcnc related so far
[07:17:17] <rootB> (._. ) isn't this cnc-linuxcnc related?
[07:17:22] <rootB> or is there a CNC only.
[07:36:14] <archivist> rootB,
https://workaround.org/getting-help-on-irc
[08:22:28] <jthornton> added a new one
http://www.gnipsel.com/glade/index.html
[08:29:28] <CaptHindsight> rootB: have you tried the #reprap channel?
[08:30:24] <archivist> has he tried asking a better question
[08:31:02] <CaptHindsight> his questions there would receive countless answers
[08:31:50] <archivist> I dont think so as although he originally mentioned a spindle problem, never gave and info about said spindle problem
[08:31:53] <CaptHindsight> and just as specific as the questions :)
[08:32:22] <archivist> hehe are they that good in there :)
[08:35:56] <eric_unterhause1> grbl replaces lcnc
[08:36:49] <archivist> in idiots dreams
[08:37:25] <archivist> geared axes in grbl?
[08:38:33] <eric_unterhause1> I never quite understood why the idea of something like a grbl was so attractive
[08:39:36] <eric_unterhause1> although if you have a 3 axis router, it should work ok once debugged
[08:41:08] <skunkworks> the mind set (talking to charles at the fest) is the rap-rep people like the idea of a 'pprinter' sind it a file iand it prints it. done
[08:41:28] <skunkworks> send it a file and it prints it.
[08:42:12] <eric_unterhausen> that's ok for a 3d printer, not so great for router
[08:42:31] <Jymmm> That's how my laser works. It just installs as a printer, you select settings, and hit START
[08:42:51] <eric_unterhausen> 3d printer doesn't have to worry about collisions
[08:42:54] <skunkworks> right - like that.
[08:44:02] <archivist> I do realise there is a mental barrier to "install linux" and setup something
[08:47:06] <eric_unterhausen> getting rt to run right is a pita, as my travails over the last week have shown
[08:48:13] <eric_unterhausen> grbl doesn't have to worry about drm in a video driver
[08:48:45] <CaptHindsight> you also chose ubuntu vs linux :)
[08:50:19] <JT-Shop> mental barrier for sure
[08:51:03] <eric_unterhausen> I assume the driver was written by someone on the debian side, ubuntu developers not that smart
[08:52:51] <JT-Shop> wow 5,555 posts on the forum
[08:54:59] <eric_unterhausen> I'm almost tempted to see if there is some obvious way to rt-ize the radeon driver
[09:00:29] <CaptHindsight> eric_unterhausen: which GPU?
[09:00:50] <eric_unterhausen> hd 78xx
[09:01:56] <CaptHindsight> ask memleak in the dev channel
[09:21:12] <cradek> archivist: that getting-help-on-irc document is quite decent
[09:34:22] <archivist> cradek, there are a number, often used in the channel bots for prompting a user to ask better questions
[09:36:24] <archivist> here is one for "ask" in my bot for another chan Don't ask to ask, Don't state: "I have a question", Don't ask: "Is anyone around?" or "Can anyone help?". Just Ask The Question. Also, please read:

[09:58:08] <JT-Shop> how rigid is it?
[09:59:57] <sivu> pretty good even without upper support
[10:00:15] <sivu> i added cross support today
[10:01:30] <sivu> and it took my weight without bending
[10:12:59] <archivist> sivu, adding a web between the two flats? as the cutting forces may bend it
[10:13:26] <sivu> yes
[10:17:59] <CaptHindsight> bits of China?? The whole country is in one time zone :)
[10:27:44] <eric_unterhausen> that must be the worlds widest time zone
[10:33:47] <CaptHindsight> yes, it crosses 4-5
[10:43:35] <IchGuckLive> Happy new year to our chinese cnc freeks
[10:44:20] <IchGuckLive> and all east of the HK boarder that are way in 2014
[10:44:42] <IchGuckLive> im on a devel of a wood mill at 20m/min
[10:44:53] <IchGuckLive> at 0,2mm precision
[10:46:15] <IchGuckLive> vitteng all parts and diameters togeter is quite a challenge to get good performence
[10:50:14] <IchGuckLive> Lucky i am
[10:50:39] <IchGuckLive> metrick rack and pinion as always fits perfect
[10:51:27] <IchGuckLive> T10 Z24 makes me a U of the pinion at 240mm
[10:51:44] <IchGuckLive> and 240mm / 0,2 pricision is 1200 steps
[10:52:02] <IchGuckLive> so 8Nm Steppers in direct mode no gear YEs im in business
[10:52:30] <IchGuckLive> now the price
[10:52:56] <IchGuckLive> 3x 36Eur for the pinion so far
[10:53:43] <IchGuckLive> 3x 130 for 3 rack 2m
[10:54:14] <IchGuckLive> and 2 x 80Eur for the 1m ones
[10:56:10] <IchGuckLive> 3 stepeppers at 100 wuros
[10:57:53] <IchGuckLive> 3 drivers at 110
[10:57:58] <CaptHindsight> IchGuckLive: our bears like German food
https://www.youtube.com/watch?feature=player_embedded&v=f6WWyxK_OaU
[10:58:35] <IchGuckLive> 2 powe supplys at 72 etch
[11:00:36] <IchGuckLive> 150 box for the 2005 in Z
[11:01:27] <eric_unterhausen> bears will eat just about anything, even German food
[11:01:50] <IchGuckLive> rails 2x 2500mm 25mm 240Eur etch
[11:05:08] <IchGuckLive> and 1 flat pair bearings for the Z at 160
[11:05:38] <IchGuckLive> and ofcause a 7i75 plag and play ads 300
[11:05:56] <IchGuckLive> 2500 Euros in total forcast so 3500 in finish mode
[11:06:05] <IchGuckLive> Thats a good price !!!!
[11:06:40] <IchGuckLive> Mumbai is on the hook to celebrade the New Year Bye ror a wile !!
[11:08:40] <CaptHindsight> they are UTC +05:30 so look for that on the bottom of most of our hours
[11:10:48] <CaptHindsight> China put itself in one time zone instead of four and India chose the middle of two time zones
[11:11:14] <CaptHindsight> kind of misses the point of time zones
[11:20:24] <eric_unterhausen> I kinda liked living in the western part of a timezone
[12:19:29] <CaptHindsight> http://www.3ders.org/articles/20131118-mtu-prof-writes-3d-printing-guide-to-making-your-own-low-cost-lab-equipment.html
[12:21:43] <CaptHindsight> it's difficult to take any guide that references repcrap and other maker garbage seriously
[12:22:33] <archivist> the pricing quoted is a bit out!
[12:23:06] <eric_u_cnc> Capt: do you have 3d printer recommendations?
[12:23:12] <eric_u_cnc> I want to buy one at work
[12:23:14] <archivist> some bs to make you buy the book
[12:23:34] <CaptHindsight> eric_u_cnc: what type? FDM, SLA etc?
[12:23:49] <eric_u_cnc> I dunno what type, blank slate
[12:24:10] <archivist> depends what you are prototyping
[12:24:23] <eric_u_cnc> I probably would be happy with a makerbot
[12:25:17] <CaptHindsight> a nice 3-axis mill that you can change from milling to deposition
[12:25:34] <eric_u_cnc> I have reasons not to get a mill
[12:25:44] <CaptHindsight> FDM head, syringe, laser etc
[12:25:45] <eric_u_cnc> basically not allowed
[12:26:23] <CaptHindsight> same design, just different tool mounted on the Z
[12:26:35] <eric_u_cnc> and our machinist just hit himself in the head with a broken endmill, so I'm worried about the machine shop
[12:27:45] <eric_u_cnc> canonical hid the software sources app
[12:29:11] <CaptHindsight> same 3-axis gantry for milling, SLA, FDM, inkjet etc etc
[12:30:05] <CaptHindsight> if you buy a makerbot or similar it will only extrude thermoplastics their way
[12:30:58] <CaptHindsight> very limited range thermoplastics
[12:31:09] <IchGuckLive> hi all B)
[12:31:25] <IchGuckLive> hapy new year if it has arrived at your location already
[12:35:30] <IchGuckLive> CaptHindsight: i ordert all 3d parts today for external printing 56Euros for all 7 parts
[12:35:35] <CaptHindsight> one of the nice things about Linuxcnc is that it may be used to control all types of 3d printers, not just glue guns
[12:35:45] <IchGuckLive> they charge 33cent for 1cm³
[12:36:12] <IchGuckLive> so no need to print it yourself
[12:36:21] <IchGuckLive> HP color 3D
[12:36:24] <CaptHindsight> IchGuckLive: what material?
[12:37:06] <eric_unterhausen> Capt: one thing I forgot to mention was the fact that I have money but no time
[12:37:10] <IchGuckLive> That is the hint they only fit one color at the da of printing so no guess yet when it will be printed
[12:39:19] <IchGuckLive> CaptHindsight ABS
[12:39:33] <CaptHindsight> ok, so extruded
[12:39:42] <IchGuckLive> never asked on that all on price for scale modelling
[12:39:58] <CaptHindsight> HP is working on a large format SLA machine
[12:40:02] <IchGuckLive> 0.1mm 11 layers per mm
[12:41:28] <IchGuckLive> is there a correction layer in the middle or iin the end someone knows this
[12:41:44] <IchGuckLive> as 0.1 *11 sent 1
[12:41:52] <CaptHindsight> eric_u_cnc: the big corporate players make expensive machines with pricey materials, the rest are mostly riding the FDM bubble
[12:41:59] <IchGuckLive> !=
[12:42:51] <IchGuckLive> i diddent know for long time that the HP offers a full slicing software for free to get code out of it
[12:43:29] <IchGuckLive> this time for the first time i had to print myself and file out the printdata to the printer service
[12:43:36] <IchGuckLive> no more stl acepted
[12:48:44] <CaptHindsight> in a few years all the rapid hybrid 3D print tech will be in China, you won't see it in the west until there is some cooperation on patents
[12:48:55] <CaptHindsight> so not for a long long time
[12:56:02] <CaptHindsight> pcw_home: will there be an FPGA board for the Cubie on the market soon?
[12:56:31] <pcw_home> I have a few if you want to play with one
[12:57:31] <pcw_home> (7I91HD Cubie --> SPI --> FPGA --> 72 I/O)
[12:57:42] <CaptHindsight> how do I order one?
[12:58:07] <pcw_home> needs:
[12:58:09] <pcw_home> Xenomai/Preemt_rt on Cubie
[12:58:10] <pcw_home> SPI HostMot2 driver
[12:58:29] <pcw_home> I can just send you one if you give me your address
[12:59:18] <CaptHindsight> no problem
[12:59:27] <pcw_home> I do have a SPI HostMot2 slave firmware working so that parts done
[12:59:51] <pcw_home> (documented in 7I90 manual)
[13:00:08] <CaptHindsight> we were going to look back at RTAI on the Allwinner as well
[13:00:15] <CaptHindsight> great
[13:01:47] <pcw_home> Neat! have you seen Tom Cubies latest?
[13:02:01] <pcw_home> radxa rock
[13:02:04] <CaptHindsight> the problem with the BBB is the slow GPU
[13:02:17] <CaptHindsight> no. not yet
[13:02:41] <CaptHindsight> the site is not loading right now
[13:03:01] <pcw_home> quad core 1.5 GHz
[13:03:03] <eric_unterhausen> someone was asking about the cubie yesterday
[13:04:09] <eric_unterhausen> search for cubie, and the 10th link is to urban dictionary. I'm afraid of what that might be
[13:04:23] <CaptHindsight> http://www.hardkernel.com/main/products/prdt_info.php?g_code=G138733896281 $59 1.7GHz Quad-Core processor and 2GByte RAM
[13:04:50] <pcw_home> I'm thinking that for us the EDM format looks like it has the most advantages
[13:04:50] <CaptHindsight> maybe hardkernel is finally getting it, they need an affordable board made in volume
[13:08:49] <pcw_home> (I notice there are at least 10 CPUS is EDM format including some x86's)
[13:09:44] <IchGuckLive> so im off for This year bye till 2014
[13:10:45] <CaptHindsight> http://www.technexion.com/index.php/products/edm
[13:11:56] <CaptHindsight> EDM Compact: 82 x 60 mm (ARM only) EDM Standard: 82 x 95 mm (ARM and x86) EDM Extended: 82 x 145 mm (x86 only)
[13:13:19] <CaptHindsight> pcw_home: are you thinking about an EDM carrier board with FPGA and slot for EDM cpu modules?
[13:14:39] <pcw_home> yes
[13:15:12] <CaptHindsight> pcw_home: will it have a 50 pin anything IO as well? or?
[13:15:29] <pcw_home> probably
[13:15:36] <CaptHindsight> high speed serial?
[13:16:54] <pcw_home> Probably first will use GPMC connection to FPGA, later will migrate to PCIE
[13:19:16] <pcw_home> I Like EDM since it gets us out of chasing the "Hot Dev board of the Month"
[13:19:18] <pcw_home> which is of course completely incompatible with the "Hot Dev board of last Month"
[13:19:55] <CaptHindsight> yeah, little to no cooperation between vendors
[13:20:32] <eric_unterhausen> see also bbw vs. bbb
[13:21:02] <CaptHindsight> often there is little to no intention of the board to be used outside of development, the panda and beagle are examples
[13:21:53] <CaptHindsight> then it gets popular
[13:22:01] <pcw_home> right
[13:24:35] <eric_unterhausen> lots of hate and discontent on bbb over dropping angstrom
[13:24:50] <CaptHindsight> I tried to work with that EOMA-68 spec but the leader of that initiative ended up a bit too kooky and announced that he patented the re-use of the PCMCIA connectors
[13:25:25] <eric_unterhausen> my garage door goes on the internet in 7 days
[13:25:37] <CaptHindsight> http://linuxgizmos.com/beaglebone-black-sbc-surpasses-100000-units/
[13:26:31] <eric_unterhausen> no wonder there are so many stupid questions on the mailing list
[13:26:40] <CaptHindsight> heh
[13:26:51] <eric_unterhausen> I delete 87% after just reading the titles
[13:27:20] <CaptHindsight> isn;t there a user/noob vs dev list?
[13:27:46] <eric_unterhausen> they should stencil something like, "it's just linux" on the board
[13:27:46] <eric_unterhausen> I don't think there is a noob list
[13:27:56] <eric_unterhausen> or rather, the bbb list is the noob list
[13:28:09] <CaptHindsight> maybe reprap will take it on
[13:28:39] <CaptHindsight> but that would just be for cnc
[13:28:46] <eric_unterhausen> the only hate for noob questions was one guy asking about a lady ada product
[13:29:04] <eric_unterhausen> which was actually perfectly fine because it was a generic question
[13:29:35] <eric_unterhausen> otherwise, stupid questions get answered or ignored for the most part
[13:30:31] <eric_unterhausen> oh, cool, someone got matlab running on bbb
[13:30:34] <CaptHindsight> often the docs are missing or skip over details that would be important for noobs
[13:31:28] <eric_unterhausen> well, that would apply in approximately 5% of the questions
[13:31:43] <eric_unterhausen> the others are just linux questions for the most part
[13:31:53] <CaptHindsight> the rest don't read the docs anyway :)
[13:31:56] <eric_unterhausen> and the wiki is pretty good anyway
[13:32:14] <CaptHindsight> why read when you can ask?
[13:32:15] <eric_unterhausen> Gerald spends most of his time providing links into the wiki
[13:33:52] <CaptHindsight> I haven't designed a single CPU board in the last year. I figured that someone would make an ARM board with a decent enough GPU and IO to support an FPGA for CNC
[13:34:13] <eric_unterhausen> I will admit that I had some confusion when first programming for beagleboard
[13:34:13] <eric_unterhausen> but then I realized it was just another linux system
[13:34:44] <eric_unterhausen> apparently the BBB is going into enough commercial products that supply is really tight
[13:34:59] <eric_unterhausen> even though they discourage if you ask
[13:35:51] <eric_unterhausen> every once in a while someone asks for a quantity discount, covered in the wiki
[13:35:51] <CaptHindsight> they never intended for the beagles to be used in products, hence the poor format
[13:36:42] <eric_unterhausen> relative to most commercial products I have dissected, the format is reasonable
[13:37:09] <CaptHindsight> looking back, if I had taken the Sitara AM3359 and made a board intended for mass production, would it have taken off?
[13:37:39] <eric_unterhausen> no, because you're not ti
[13:37:53] <pcw_home> Probably not unless subsidized by TI
[13:38:15] <eric_unterhausen> haven't similar things been offered on kickstarter?
[13:38:16] <CaptHindsight> the Allwinner SOC's are very popular in China for tablets, Mediatek for phones
[13:39:04] <CaptHindsight> wasn't there the Freescale imx6 + Atmel in a duino form factor?
[13:39:36] <pcw_home> Yes, forgot the name though
[13:40:08] <Jymmm> IBM Model 2
[13:40:25] <CaptHindsight> http://www.kickstarter.com/projects/435742530/udoo-android-linux-arduino-in-a-tiny-single-board/posts/456046
[13:41:12] <CaptHindsight> andy was still waiting for his last time I asked
[13:41:22] <eric_unterhausen> I always like the kickstarters that get over-funded by 20x like that
[13:41:27] <eric_unterhausen> and then fail
[13:42:04] <eric_unterhausen> is it the over-funding, or was the original estimate of how much $ were required off by more than 20x?
[13:42:42] <eric_unterhausen> I know someone that should have gone on kickstarter, he made a really nice iphone case
[13:43:02] <eric_unterhausen> instead, he put it on a website and I can't even find a link to it
[13:43:23] <CaptHindsight> boards like that take me a few weeks from laundry list to final BOM and design files
[13:43:38] <eric_unterhausen> so they just didn't know what they were doing
[13:43:49] <CaptHindsight> you need to have a good supply chain for parts
[13:43:51] <eric_unterhausen> although at my rates, a few weeks would be 27k :)
[13:44:10] <CaptHindsight> not just Digikey, Mouser and Avnet
[13:46:51] <CaptHindsight> http://wandboard.org/index.php?start=10 is also on EDM
[13:48:05] <pcw_home> Wandboard was the first I think
[13:49:36] <CaptHindsight> I can see how to make an EDM module with a shell like a PC-CARD
[13:53:16] <CaptHindsight> to tool up for a connector in China is only a few $K
[13:56:00] <CaptHindsight> I like the idea of a module in a shield/case like a PC-CARD you can swap between gadgets
[13:57:18] <CaptHindsight> the bad side is that it's not good for sales if you can just upgrade a product by swapping modules
[14:01:46] <Jymmm> That's pretty good (slide the top image)
http://www.kickstarter.com/team
[15:50:59] <CaptHindsight> PCW: wow, rockchip posted kernel source on github
[15:51:13] <CaptHindsight> https://github.com/linux-rockchip/rockchip-3.0
[15:51:36] <CaptHindsight> http://wiki.radxa.com/Main_Page interesting
[15:57:04] <PCW> so a low cost RK3188 EDM card would be nice
[15:57:30] <PCW> the RK3188 has a GPMC of some sort
[16:03:47] <CaptHindsight> rockchip used to violate gpl by only releasing kernel source under NDA with an SDK
[16:05:03] <PCW> maybe the are wising-up
[16:05:11] <CaptHindsight> I wonder of the pressure from Alwinner releasing all their source had any effect
[16:05:23] <CaptHindsight> maybe
[16:06:14] <PCW> http://www.youtube.com/watch?v=_goEernujW8
[16:08:20] <CaptHindsight> well voices carry
[16:17:25] <CaptHindsight> http://www.ebay.com/itm/191016483320 $3500 for a plasma table minus the plasma cutter?
[16:24:36] <mozmck> Not real expensive, but looks pretty cheap.
[16:25:34] <mozmck> One advantage is it looks to be all bolt-together so it could be shipped easily.
[17:17:07] <CaptHindsight> anyone ever try using two encoder tapes wrapped around a cylinder and read heads to reduce the cost of using one angle encoder?
[18:00:28] <andypugh> What a marvellous doible-entendre: "but yesterday Chas was reaming his mother's bush for
[18:00:28] <andypugh> a large part of the afternoon, while we looked on and admired his
[18:00:29] <andypugh> style."
[18:11:05] <andypugh> This is what I did with my Christmas. This:

[18:32:09] <Tom_itx> very nice andypugh
[18:32:11] <Tom_itx> so
[18:32:17] <Tom_itx> how you gonna top that for the new year??
[18:32:31] <andypugh> Guess what it is :-)
[18:33:04] <Tom_itx> not a pile of lumber anymore
[18:34:58] <andypugh> http://www.deprecision.com/RivettLathe.com/images/cummins_608l.jpg
[18:35:35] <Tom_itx> copied from that?
[18:35:53] <andypugh> I spent more than twice what the lathe cost plus 10 days of work to make a stand for a lathe I don't need :-)
[18:36:07] <Tom_itx> but
[18:36:14] <Tom_itx> you're making a showpiece out of it
[18:36:38] <andypugh> Yeah, because the only place I have space for it is my front room :-)
[18:36:48] <Tom_itx> heh
[18:37:43] <Tom_itx> did you see how my engraving turned out?
[18:38:28] <andypugh> No, I have been basically offline all Christmas / Andymas.
[18:38:36] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/pendant/pendant2.jpg
[18:38:43] <Tom_itx> i tried a couple different depths
[18:39:02] <Tom_itx> bottom was about .010" top around .035" or so
[18:39:16] <andypugh> The lower ones may be a little too subtle?
[18:39:20] <Tom_itx> not perfect but workable
[18:39:32] <Tom_itx> i may flycut it and try again
[18:39:56] <andypugh> You should be able to rust re-engrave. This is CNC :-)
[18:40:03] <andypugh> (just)
[18:40:10] <Tom_itx> yeah but we're talking about sherline here
[18:40:21] <andypugh> Ah.
[18:40:44] <andypugh> Buy something in the half-ton class. I really don't regret it.
[18:40:48] <Tom_itx> wasn't sure what to expect from the new bits
[18:41:29] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/pendant8.jpg
[18:41:35] <Tom_itx> much better than trying to use a drill bit
[18:43:10] <andypugh> That worked quite well considering.
[18:43:34] <andypugh> Engraving bits seem to have a geometry you would never guess.
[18:48:42] <Tom_itx> we used to use fairly long half round bits for deep hole drilling brass on the old old New Brittans making barb fittings etc
[18:48:48] <Tom_itx> very similar to that
[18:53:39] <andypugh> I have a tobacco tin full of such things, and no idea what they are for. :-)
[19:29:51] <Tom_itx> http://www.mscdirect.com/product/01150127
[19:29:55] <Tom_itx> just like those
[19:31:56] <Jymmm> Tom_itx: At the bare minimum, do atmels need an external osc/crystal?
[19:32:41] <Tom_itx> no
[19:32:52] <Tom_itx> afik they all have internal oscillators
[19:33:03] <Jymmm> thanks
[19:33:06] <Tom_itx> if you want better accuracy you need one
[19:33:17] <Tom_itx> some have internal calibration bits
[19:33:41] <Tom_itx> and default to the lowest denominator
[19:33:45] <Jymmm> Tom_itx: I want to program on an arduino, then pull out the chip and insert another one
[19:33:47] <Tom_itx> ie generally 1Mhz
[19:33:48] <andypugh> Tom_itx: Looks like a gun-drill?
[19:33:55] <Tom_itx> very much
[19:34:05] <Tom_itx> used mostly for long holes in brass
[19:34:29] <Tom_itx> Jymmm, as long as you don't screw up the fuse bits that works
[19:34:52] <Tom_itx> i made a fixture for attiny2313 but added a redundant crystal to the bottom just in case
[19:35:19] <Jymmm> Tom_itx: It's just to make a bunch of led blinky things
[19:35:47] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/attiny2313/attiny9.jpg
[19:35:57] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/attiny2313/attiny8.jpg
[19:36:01] <Tom_itx> bottom of it
[19:36:23] <Tom_itx> thumb held programming at it's best
[19:36:56] <Jymmm> if I cna help it, I dont even want a PCB
[19:37:35] <Tom_itx> how you gonna attach the power and isp pins?
[19:37:42] <Tom_itx> dip chips?
[19:37:42] <andypugh> ROFL. (well, actually, I smirked silently)
http://en.wikipedia.org/wiki/Gun_drill seems to have some too-literal imperial to metric conversions.
[19:38:09] <Jymmm> Tom_itx: just hard wire it
[19:38:24] <Jymmm> Tom_itx: direct to the DIP chip
[19:38:47] <Tom_itx> andypugh, those aren't quite half round
[19:39:03] <Jymmm> Tom_itx: maybe get a wirewrap socket
[19:39:32] <eric_unterhausen> hoho, even after reinstalling ubuntu, the commands I hosed it with previously are still in my bash history
[19:40:39] <andypugh> I wonder if you could make super-straight rifle-barrels with spark-erosion?
[19:41:01] <eric_unterhausen> how do you keep the sparker from drooping?
[19:41:14] <andypugh> Erode vertically
[19:41:21] <eric_unterhausen> duh
[19:42:14] <andypugh> (sorry)
[19:42:17] <eric_unterhausen> haha
[19:42:25] <eric_unterhausen> i am a little slow
[19:43:28] <eric_unterhausen> looks like vesa and opengl are working after my reinstall
[19:44:43] <CaptHindsight> andypugh: did you ever get your imx6 + arduino board?
[19:45:12] <andypugh> Apparently it has been left next-door (just got home)
[19:49:02] <eric_unterhausen> I bought 3 compact flash to sata converters, the only one I wasn't using was bad
[19:49:06] <eric_unterhausen> too late to send it back
[19:49:38] <Tom_itx> Jymmm, don't forget you need a pullup on reset and all the power pins need connecting
[19:49:56] <eric_unterhausen> input connector visibly crooked
[19:53:15] <eric_unterhausen> CaptHindsight, how do you tell if memleak is on?
[19:55:35] <CaptHindsight> he's gone until tomorrow night
[19:57:18] <eric_unterhausen> linux purists strike again
[19:57:55] <eric_unterhausen> http://pastebin.com/1zamrMwt non-gpl module causes error
[19:59:29] <eric_unterhausen> sometimes it's enough to make you want to use BSD
[20:06:52] <andypugh> eric_unterhausen: I do ue BSD. Well, the OSX flavour.
[20:07:28] <eric_unterhausen> w/linuxcnc?
[20:09:45] <andypugh> No, though it has been done, apparently
[20:10:06] <eric_unterhausen> yeah, plus I have no patience for that anyway
[20:12:10] <eric_unterhausen> curious that it failed referencing fglrx.ko, doesn't seem like that should be part of the rtai kernel
[20:12:32] <eric_unterhausen> maybe that's some cruft on my system
[20:22:43] <eric_unterhausen> would it be fair to say that linux is written by people that benefit monetarily by linux having problems?
[20:23:23] <andypugh> No.
[20:23:43] <eric_unterhausen> because the purist kernel thing doesn't make sense to me otherwise
[20:24:00] <andypugh> I know hardly anyone who benefits from Linux o=monetarily at all
[20:24:04] <eric_unterhausen> torvalds certainly does
[20:24:09] <eric_unterhausen> and it was his decision
[20:24:23] <andypugh> As does my Linux-fellow friend.
[20:25:11] <andypugh> But they do better when it works.
[20:25:25] <eric_unterhausen> it almost works, that's the sweet spot
[20:25:52] <eric_unterhausen> not quite right, works most of the time
[20:26:58] <andypugh> http://lwn.net/Articles/419640/ is a long-time friend. It came as something of a surprise to find that he was a Linux Dude, I think he was equally surprised to find that I dabble too. We are in the same bike club. :-)
[20:27:06] <eric_unterhausen> just annoyed because torvalds doesn't understand that decisions like that hurt the linux user base more than whatever target he was aiming at
[20:27:27] <cradek> eric_unterhausen: are you sure you're mad at the right people?
[20:28:19] <eric_unterhausen> the software is deliberately broken by the linux folks
[20:29:03] <eric_unterhausen> not really angry, not even annoyed
[20:29:07] <eric_unterhausen> just spouting
[20:31:37] <cradek> fglrx is proprietary trade-secret hiding binary blob driver stuff made by a company that keeps secrets in order to protect their ability to profit off of you. torvalds has given decades of work to you under a license that tries to protect your freedoms.
[20:32:08] <eric_unterhausen> I could tolerate it back in the day when it said some module was tainted
[20:32:22] <eric_unterhausen> actually breaking my system is over the line, imho
[20:32:59] <eric_unterhausen> i don't even want fglrx, but since it's on my system, the command fails
[20:33:07] <andypugh> I think this photo nicely sums up the srurdy nature of the cabinet:
https://picasaweb.google.com/lh/photo/7Mx5qLVvlDrTPlJxXtSNN9MTjNZETYmyPJy0liipFm0?feat=directlink
[20:33:09] <eric_unterhausen> is that a bug or what?
[20:33:29] <cradek> well then get rid of it?
[20:34:06] <eric_unterhausen> I was trying to figure out where it came from, but the buggy software didn't exactly give me any hints
[20:34:12] <eric_unterhausen> from what I could see
[20:34:23] <tjtr33> nice work andy
[20:35:56] <RyanS> Interesting concept and somewhat accurate but really, $66
http://www.acmetools.com/tools/STARRETT+18SB+Spacing+Attachment+for+No.+18B
[20:36:06] <andypugh> I have loads of work to come on finishing it. I still need to decide if I shoulf fume it to make ot look the same age as the lathe.
[20:39:38] <eric_unterhausen> fume it
[20:40:28] <andypugh> RyanS: If you do that a lot then $66 is cheap (it would pay back in a day). If you do it rarely, then you have your dividers. If someone offered me £40 to make that, I would politely refuse. I suspect that they haven't set up for volume production of a rarely-required widget.
[20:41:48] <andypugh> eric_unterhausen: I don't like faking. It's brand-new, perhaps it should look new until it isn't?
[20:42:07] <eric_unterhausen> fuming was done when the lathe was made :)
[20:42:28] <eric_unterhausen> if you said you were going to stain it, that's a different matter
[20:46:20] <RyanS> true
[20:47:41] <andypugh> All the oak here (except for one 500 year old original beam) has just been ignored for 10 years. It doesn't take that long to get a natural patina.
https://picasaweb.google.com/lh/photo/UbuI899a2pJFu8778cuNCNMTjNZETYmyPJy0liipFm0?feat=directlink
[20:47:53] <eric_unterhausen> then again, if you just shellac it, it starts looking fairly old right away
[20:48:48] <eric_unterhausen> I've never fumed anything, but to get patina you would want to use a very dilute solution or it turns black
[20:48:48] <RyanS> And would take a fair bit of fiddling around to make. I guess
[20:49:32] <andypugh> You don't use a solution, you build a tent and put a suceer of ammonia in it
[20:49:45] <eric_unterhausen> evil amd guys promised me an uninstall script, it's not there
[20:49:52] <eric_unterhausen> bastages
[20:52:52] <RyanS> Speaking of turning stuff black.anyone tried cold black oxide treatment for steel?
[20:53:03] <eric_unterhausen> bluing?
[20:53:16] <Tom_itx> not bluing
[20:53:20] <Tom_itx> it's different
[20:53:25] <Tom_itx> and no i haven't tried it
[20:53:33] <RyanS> yeh . It's sort of
[20:53:35] <eric_unterhausen> I'm going to blue one of my bike frames
[20:53:49] <Tom_itx> proper bluing is done with heat
[20:53:53] <RyanS> There is cold and hot methods
[20:53:55] <Tom_itx> this is chemical
[20:54:06] <eric_unterhausen> that's why I'm going to have it powder coated after I blue it
[20:54:17] <andypugh> The Wiki page is informative.
http://en.wikipedia.org/wiki/Bluing_(steel)
[20:54:44] <RyanS> hot is better but apparently quite dangerous in a home workshop
[20:54:55] <RyanS> Toxic chemicals
[20:55:14] <eric_unterhausen> I'm going to guess that the cold methods use chemicals you don't want to drink
[20:55:36] <RyanS> That's true, but fumes
[20:55:51] <RyanS> brb
[20:56:52] <andypugh> You can polish and blue with no chemicals. But it is anyones guess what you would do to the tube heat-tratment. But then if they are alloyed to survive lug-brazing, it is probably no concern.
[20:59:38] <eric_unterhausen> so you can fume your oak with the same stuff as they fume guns with
[20:59:51] <andypugh> Try just polishing and a blow-torch if it is 531 or similar brazable steel, they don't really care what you do, that's their raison d'etre
[21:02:41] <eric_unterhausen> that's funny, speedvagen did that a while back to put the heat affected zone on before powder coating
[21:02:49] <eric_unterhausen> I think it would be tricky to make it uniform
[21:03:22] <eric_unterhausen> you usually get some black
[21:05:31] <somenewguy> huh, regardless of where the error is, it keeps claming its on the last line....
[21:05:32] <andypugh> You can try again as many times as it takes
[21:06:27] <eric_unterhausen> I usually use heat treated tubes, so I'd rather not mess with it when I can get a can of blue for a few bucks
[21:07:32] <somenewguy> ...nvm I continue to be an idiot
[21:18:02] <somenewguy> also sprunge is the coolest thing ever btw
[21:19:21] <andypugh> eric_unterhausen: How do you join the tubes?
[21:25:39] <RyanS> So black oxide bolts are usually made so during heat treatment. I guess
[21:31:43] <eric_u_cnc> andypugh, I either use lugs or fillet braze
[21:31:51] <eric_u_cnc> never learned how to tig
[21:32:18] <andypugh> So, the lugs get far hotter than blueing temp.
[21:32:29] <eric_u_cnc> fillet is hotter yet
[21:33:01] <eric_u_cnc> I forget my color chart
[21:33:39] <eric_u_cnc> but I'm pretty sure it would be hard to get a consistent color
[21:33:50] <eric_u_cnc> the blue doesn't show up until it cools
[21:34:10] <andypugh> The "special trick" of 531 is that is is cold-drawn to high strength and retains that strength through brazing. I am pretty sure you can hot-braze it safely
[21:34:49] <andypugh> (sorry, I meant hot-blue it)
[21:34:58] <eric_u_cnc> none of the heat treated tubing loses any significant strength through brazing
[21:35:18] <eric_u_cnc> I don't know if anyone around here does that
[21:35:54] <andypugh> The dark blue is easy. The lighhter colours less so.
[21:36:22] <andypugh> A bit of a spectrum thing might actually look rarther nice
[21:36:39] <andypugh> it only costs time to try it.
[21:36:56] <eric_u_cnc> i have occasionally wondered why reynolds doesn't make 531 anymore
[21:37:00] <eric_u_cnc> they have moved on
[21:37:22] <andypugh> Competition.
[21:37:42] <RyanS> hmm not sure I see the difference between hot black oxide and hot blueing
[21:37:42] <eric_u_cnc> pretty sure they would sell enough to make it worthwhile
[21:37:46] <andypugh> The new stuff is probably TIG-able etc.
[21:38:01] <RyanS> Cold black oxide seems pretty pointless. However
[21:38:11] <eric_u_cnc> they have a fairly extensive product line, some of it very 531-like
[21:39:35] <eric_u_cnc> columbus sells something called "sl" that is nothing like the old stuff, it's marketing
[21:42:10] <andypugh> 953 is basically twice as strong, and it is stainless too.
[21:43:03] <eric_unterhausen> too much money for me
[21:43:10] <RyanS> TIG looks like it would be fun to learn. can braze dissimilar metals as well as well as only requiring 1 type of gas
[21:43:35] <andypugh> Full list here:
http://en.wikipedia.org/wiki/Reynolds_Cycle_Technology
[21:44:32] <RyanS> A lot more versatile but slower than any other welding process. It seems
[21:45:40] <eric_unterhausen> I think I could pick up tig pretty fast, but I don't feel like spending $3kusd on it
[21:46:00] <RyanS> You don't need to spend that much
[21:46:06] <andypugh> You don't need to.
[21:46:13] <RyanS> Especially if you don't need to aluminium
[21:46:16] <eric_unterhausen> it adds up pretty fast
[21:47:11] <RyanS> its aluminium that requires AC and more expensive equipment,
[21:47:17] <eric_unterhausen> if I went with tig, it would be for Ti
[21:47:32] <eric_unterhausen> there is no reason for me to tig a steel frame
[21:47:37] <RyanS> I think you can do that with DC
[21:48:06] <andypugh> This has HF start and is $300. (or suggests so)
[21:48:07] <andypugh> http://www.ebay.com/itm/2-in-1-TIG-DC-PULSE-FREQUENCY-HF-WELDER-200-AMP-MOSFET-INVERTER-MMA-ARC-STICK-/321245302013?pt=BI_Welders&hash=item4acbb64cfd
[21:48:15] <eric_unterhausen> I asked a friend why he didn't build aluminum, he told me that you can get a reasonably good frame from Tiawan for $25
[21:48:57] <RyanS> am not sure, however, but titanium is a bitch to weld
[21:49:17] <eric_unterhausen> all the people I know that want me to build them a frame want Ti
[21:49:37] <andypugh> Though you might as well go for a HF / AC set like
http://www.ebay.com/itm/Power-I-TIG-200T-TIG-WELDER-/171137324069?pt=BI_Welders&hash=item27d8945425 so that you can do Aluminium too.
[21:49:41] <eric_unterhausen> just when the bicycle Ti tube makers have quit making tubes
[21:50:03] <eric_unterhausen> I've heard the everlast welders are pretty good
[21:50:19] <RyanS> I think you have to back purge everything with titanium
[21:50:28] <eric_unterhausen> yeah, purge is expensive
[21:50:30] <andypugh> If I wanted to make a Ti frame I would use glue and machined lugs.
[21:51:00] <eric_unterhausen> if I wanted to make a Ti frame, I would buy some stainless :)
[21:51:03] <andypugh> Sleep time
[21:51:07] <Tom_itx> aww
[21:51:09] <Tom_itx> it's the new year
[21:51:14] <Tom_itx> stay up and party!
[21:51:30] <Tom_itx> guess he didn't fall for it
[21:51:30] <eric_unterhausen> isn't it 4am there?
[21:51:38] <Tom_itx> something like that
[21:51:55] <eric_unterhausen> if I go to bed after 3, I might as well skip it
[21:52:23] <RyanS> AC and high-frequency start would seem like the best features, but I don't know if you need things like ac balance , up/down slope. I think post gas is pretty important
[21:53:19] <eric_unterhausen> there was a big kerfluffle recently because one of the high-end frame companies wasn't using enough gas
[21:53:34] <eric_unterhausen> and their welds were a nice blue color
[21:53:50] <eric_unterhausen> which is unacceptable for just about anyone that cares about weld longevity
[21:54:20] <jdh> you have to use helium with Ti?
[21:54:58] <eric_unterhausen> helium is in short supply, everyone uses argon unless it's really high value piece
[21:55:37] <jdh> short supply where?
[21:55:40] <eric_unterhausen> helium used to be produced by the U.S. gvmnt, they tried to get private industry to make it but it didn't happen
[21:55:51] <jdh> stockpiled
[21:55:56] <RyanS> helium I think is for a higher current really thick stuff
[21:56:15] <eric_unterhausen> yeah, but we've been drawing down the stockpile for a while
[21:56:37] <RyanS> Also, argon is heavier than air so it stays where you want it apparently
[21:57:10] <eric_unterhausen> it's just not as good
[21:57:35] <eric_unterhausen> BITD, they called TIG "heliarc"
[21:57:47] <eric_unterhausen> not argoarc
[21:57:59] <RyanS> eric_unterhausen
http://lostgarage.com/blogs/news/8182739-tig-welders-compared-miller-dynasty-200dx-vs-everlast-powertig-200dx . This is a good review
[21:58:30] <RyanS> But I don't think anyone really uses helium unless it some special reason
[21:59:05] <eric_unterhausen> the bike guys imply that argon is a bit expensive because they use so much
[21:59:14] <eric_unterhausen> 1 frame = a tank
[22:00:05] <eric_unterhausen> when I first looked, the Dynasty cost $1700, price has been going up precipitously since then
[22:00:05] <RyanS> Surely not 8lpm -10 is usually the amount
[22:00:30] <eric_unterhausen> I dunno, this is what I read
[22:00:32] <RyanS> $5000 machine
[22:00:38] <eric_unterhausen> they also back-purge
[22:00:54] <RyanS> That could be why
[22:00:59] <eric_unterhausen> I haven't figured out what Miller was up to
[22:01:14] <eric_unterhausen> I somehow doubt their costs have doubled
[22:01:58] <RyanS> I think it's more like duty cycle... You pay more for that if you are going to welding all day long
[22:02:17] <eric_unterhausen> Dynasty doesn't have a great reputation
[22:02:22] <eric_unterhausen> people want synchrowaves
[22:03:04] <jdh> I pay $89 for 300ft^3 of HP-Helium
[22:03:09] <jdh> used to be $59
[22:03:28] <eric_unterhausen> don't they pay you to take argon?
[22:03:42] <RyanS> How thick is the tube for bike frames?
[22:04:04] <eric_unterhausen> not sure about Ti, steel is .7 mm
[22:04:09] <eric_unterhausen> in the welded areas
[22:04:31] <RyanS> Don't think need much amps for that
[22:04:40] <eric_unterhausen> no, the lowest setting
[22:05:14] <eric_unterhausen> it's like the old welders that would cut a coke can in half and weld it back together
[22:08:02] <eric_unterhausen> at the end of the miller/everlast comparo, they talk about getting good helmets
[22:08:19] <eric_unterhausen> apparently a lot of welders like the $50 HF auto-darkening helmet
[22:08:46] <eric_unterhausen> surprised me, I figured everything in HF was worse than trash
[22:08:59] <RyanS> I think I'd be a bit worried when dealing with my eyeballs
[22:09:08] <RyanS> Think I'd rather spend the extra cash
[22:09:20] <RyanS> http://www.everlastgenerators.com/Power-I-Tig-200-348-pd.html this can do everything but aluminium
[22:09:33] <eric_unterhausen> that's the thing, they say it's no worse than the high-price spread
[22:09:48] <eric_unterhausen> you will get flashed with a auto-darkening helmet from what I hear
[22:11:19] <RyanS> yeh also apparently the better ones react to the electromagnetic 'signature' of tig
[22:11:41] <RyanS> So they react before the ARC even strikes
[22:12:09] <eric_unterhausen> the guys I know use gold plated lenses on their helmets
[22:12:24] <RyanS> Interesting
[22:12:26] <eric_unterhausen> I have enough eye problems I'm not sure I would bother with auto-darkening
[22:12:38] <eric_unterhausen> the fixed lenses are reasonably priced
[22:13:16] <RyanS> yeh u can just get into the habit of flipping it down
[22:13:48] <eric_unterhausen> it always drove me crazy to see the guys on tv weld with their eyes shut
[22:14:03] <eric_unterhausen> jessie james, for example
[22:14:11] <RyanS> someone said you can use a flashlight, but I can't see how that would give any visibility
[22:14:57] <RyanS> In the US you can also purchase a gas bottle? You don't have to do a lease?
[22:15:09] <eric_unterhausen> just small ones
[22:15:20] <eric_unterhausen> I own my own oxygen/acetylene tanks
[22:15:35] <eric_unterhausen> I am thinking about getting an oxygen concentrator and using propane
[22:16:08] <RyanS> Can't even purchase in Australia. You have to rent because the gas suppliers won't refill
[22:16:21] <eric_unterhausen> in a lot of places you aren't supposed to have acetylene in a house or attached garage, and they can't deliver to a residential address
[22:16:56] <eric_unterhausen> I bought my tanks from my gas supplier
[22:17:02] <RyanS> I don't even think it's regulation. I think it's monopolistic gas companies who make a great deal out of rental
[22:17:27] <eric_unterhausen> when I first started buying gas, they just gave you the bottles
[22:17:43] <eric_unterhausen> gave == lent
[22:18:08] <eric_unterhausen> so it's funny to see someone selling grandpa's bottles, because they probably belong to the gas company
[22:18:20] <eric_unterhausen> they always want top dollar too
[22:18:33] <RyanS> hmm, is Oxy fuel welding anything like an alternative to tig?
[22:18:46] <RyanS> As far as versatility?
[22:18:59] <eric_unterhausen> you can't do non-ferrous metals
[22:19:14] <RyanS> Except in Australia. That means renting and two bottles rather than just argon
[22:19:27] <RyanS> You can't weld aluminium?
[22:19:50] <eric_unterhausen> there are ways of doing it, but it's not great
[22:19:56] <RyanS> Maybe they just braze
[22:20:16] <eric_unterhausen> yeah, I think there is aluminum brazing rod
[22:20:24] <eric_unterhausen> but it is not particularly strong
[22:21:10] <eric_unterhausen> for making bikes and glasswork, an oxygen concentrator and propane makes sense
[22:21:36] <eric_unterhausen> I assume you can still use a gas grill in Australia?
[22:22:17] <eric_unterhausen> and there is a constant supply of oxygen concentrators because the medical supply companies make more money selling new ones
[22:22:23] <RyanS> You can own barbecue bottles, no problem, just not industrial gas
[22:22:47] <eric_unterhausen> which is funny because propane is heavier than air, so more likely to blow up your house
[22:23:33] <RyanS> does a good air propane torch have enough ooomph for annealing or really you need oxygen?
[22:24:05] <eric_unterhausen> I don't think you would be happy with it
[22:24:20] <eric_unterhausen> they do make better air-propane torches, I have no experience with them
[22:24:47] <eric_unterhausen> playing tricks with heat bricks is probably in order
[22:26:00] <RyanS> http://www.weldmart.com.au/img/products/Turbo%20200.jpg you can use these but the problem is the fuel will last a couple of hours . However, the oxygen less than 30 minutes If you're lucky
[22:29:36] <RyanS> I suppose plenty of people build a little gas forge
[22:31:25] <eric_unterhausen> yeah, you want to use a tank for a grill and an oxygen concentrator
[22:31:45] <eric_unterhausen> in the u.s., the oxygen concentrators go for $300-500
[22:32:21] <eric_unterhausen> Austrailians are healthier, so they cost more due to lack of supply
[22:32:37] <RyanS> yeh, I think you can also use forced air
[22:33:01] <RyanS> Not sure aren't we supposed to drink a lot
[22:33:16] <eric_unterhausen> I believe so
[22:33:34] <RyanS> I don't even like beer. It's horrible
[22:33:58] <eric_unterhausen> ok, I'm surprised you aren't off floating on an iceburg with that comment
[22:34:18] <RyanS> An iceberg?
[22:34:35] <eric_unterhausen> banished
[22:34:40] <RyanS> I'm into good spirits
[22:34:54] <eric_unterhausen> no, I mean involuntarily
[22:35:17] <eric_unterhausen> although having friends that won't drink your beer can be a good thing
[22:35:21] <RyanS> As in hard liquor
[22:35:46] <RyanS> Cocktails..
[22:36:28] <RyanS> I don't do wine or beer
[22:40:40] <eric_unterhausen> now I'm learning more than I want to about dkms
[22:41:53] <RyanS> dkms?
[22:42:12] <eric_unterhausen> dynamic kernel module system
[22:42:26] <eric_unterhausen> it builds kernel modules if you install a new kernel
[22:42:39] <eric_unterhausen> keeping me from installing the rtai-headers
[22:43:22] <RyanS> I know nothing about linux :P I'm just here to talk about metal work
[22:43:46] <eric_unterhausen> I'm fond of metalworking myself
[22:44:57] <eric_unterhausen> although most recently I've been grinding glass
[22:46:04] <RyanS> urgh building your own propane burner sounds a bit risky
[22:46:45] <eric_unterhausen> it's usually pretty cheap to buy
[22:47:07] <eric_unterhausen> libfglrx_ip.a is apparently the evil binary blob
[22:48:58] <eric_unterhausen> ok, taking bets on if i'm about to hose my system
[22:49:57] <RyanS> http://www.youtube.com/watch?feature=player_detailpage&v=jBVa2bw3r_k#t=164 . I like this idea, but using a propane torch with a barbecue bottle
[22:51:15] <eric_unterhausen> ya, heat bricks
[22:52:09] <eric_unterhausen> yay, no hosed system
[22:52:30] <eric_unterhausen> too bad I have to go to the basement to reboot the computer
[22:53:34] <eric_unterhausen> I had an electric oven that would heat treat, but the last thing I needed was another project so I gave up on it
[22:53:43] <eric_unterhausen> gave it to a starving artist
[22:54:32] <eric_unterhausen> I have successfully heat treated O2 steel with an acetylene torch, so having an oven was surplus anyway
[23:07:56] <RyanS> We have all this steel, stainless and aluminium engineering stock at home but who knows specifically what type.. Some of them still have text like 316 stainless etc but the rest is just a guess
[23:11:03] <RyanS> My old man purchased two cabinets from a Kodak insolvency sale I guess business still had in-house machine shops for repairs and replacement parts
[23:11:31] <RyanS> Lots of stock metal
[23:58:22] <rootB> hey linuxcnc
[23:58:30] <rootB> Do you got experience using a proxon spindle?
