Back
[00:01:57] <XXCoder> thanks
[00:02:28] <furrywolf> in fact, you should read ALL the sam's faqs. they cover everything from lasers to microwaves to lawnmowers to dishwashers. :P
[00:02:44] <XXCoder> lol ok
[00:04:54] <furrywolf> too bad a lot of it is outdated... it hasn't been updated since the section on fixing VCRs was useful...
[00:05:22] <XXCoder> I can tell. it contains gripe about animated gifs
[00:06:05] <furrywolf> no, that's still relevant.
[00:06:17] <XXCoder> well yes
[00:06:28] <XXCoder> back then its loading time, now its annoyance factor
[00:06:31] <furrywolf> it's something designers of certain modern OSes should read, too.
[00:06:43] <furrywolf> I do not want my icons to bounce.
[00:09:56] <furrywolf> he has sections on all sorts of random things... how to make scrap x-ray machines functional... audio amp repair... video conversion... lawnmowers... etc.
[00:13:21] <furrywolf> bbl, wolfy bedtime
[00:58:00] <zeeshan> ah so much wiring
[00:58:02] <zeeshan> all i/o is done.
[00:58:10] <zeeshan> only servo wiring left
[00:58:12] <zeeshan> hooray
[01:04:04] <Jymmm> I/O, I/O, It's off to work we go...
[02:24:38] <Deejay> moin
[04:36:31] <bobo_> zeeshan it has been over 3 hours
[04:37:05] <bobo_> is it wired up now ?
[04:37:56] <bobo_> what is the problem ?
[04:43:19] <archivist_herron> past his bedtime!
[04:44:09] <bobo_> kids these days
[08:09:05] <JT-Shop> anyone build a forge to melt brass?
[08:23:05] <cradek> I've done it in a gingery furnace
[08:24:07] * JT-Shop looks that up
[08:25:02] <malcom2073> Does it have a red top?
[08:25:18] <jdh> or a soul?
[08:25:40] * syyl_ws felt of his chair
[08:28:39] <JT-Shop> cradek, you use propane to fire the furnace?
[08:30:53] <archivist_herron> check colour of brass scrap to get a similar mix
[08:33:02] <JT-Shop> you mean red vs yellow brass?
[08:33:35] <JT-Shop> I have about 400lbs of yellow brass scrap and 100lbs of red brass scrap
[08:33:48] <archivist_herron> yes and the pale casting brass (soft)
[08:34:28] <JT-Shop> ok, seperate cast brass from wrought brass
[08:35:00] <archivist_herron> they often die cast the normal yellow
[08:35:38] <archivist_herron> how it files can show a hard v soft
[08:36:17] <JT-Shop> ok, good info to know
[08:39:17] <archivist_herron> and....I want to do it one day
[08:42:58] <JT-Shop> I have a 77 year old friend that used to cast gold and silver and I need a hobby for him and me
[08:43:19] <jdh> how about casting gold and silver?
[08:43:33] <Jymmm> bank robbery of ols stage coaches?
[08:43:38] <Deejay> lol
[08:43:39] <Jymmm> old*
[08:43:50] <Jymmm> Jewlerysmithing
[08:45:07] <Jymmm> you guys can come up with jewlery designs, cnc the molds for lost wax casting
[08:46:57] <jdh> or take up the lost art of strip club patronage
[08:47:07] <Jymmm> belt buckles, vest pins
[08:47:49] <Jymmm> jdh: But thats just looking no touching = prick tease. They should go into pimping and hustling instead.
[08:47:58] <jdh> he's 77
[08:48:08] <Jymmm> viagra?
[08:48:42] <malcom2073> So his pimp cane will be legit
[08:48:45] <Jymmm> JT-Shop: can be the brawn and the 77yo the brains
[08:48:46] <Deejay> lol
[08:48:53] <Jymmm> malcom2073: EXACTLY
[08:49:30] <Jymmm> and since they cast gold, JT-Shop will look natural with gold capped teeth
[08:49:48] <archivist_herron> cnc my ride
[08:49:49] <jdh> mail order grillz
[08:50:04] <Jymmm> There we go!
[08:50:34] <Jymmm> lol @ archivist_herron. you get that show in the UK ?
[08:50:36] <malcom2073> Yo I heard you like cnc's in your cnc so I cnc'ed your cnc!
[08:50:57] <jdh> that's probably too close to accurate to be funny
[08:51:07] <archivist_herron> Jymmm, we did get some
[08:51:17] <Jymmm> archivist_herron: ah
[08:51:20] <malcom2073> I met someone who worked at one of the shops they used, the only redeeming value, is that they thought it was stupid as it actually was
[08:52:05] <Jymmm> JT-Shop: I think if you made custom pins/logos/embelems you might have something.
[08:52:24] <archivist_herron> I did some hanger on for a TV show, stuff for the masses is low quality
[08:53:10] <archivist_herron> hand engrave the resultant brass
[08:53:51] <Jymmm> Man Cave stuff
[08:54:39] <Jymmm> and when ya screw up, just remelt
[08:55:15] <archivist_herron> nah just file down a bit and re engrave
[08:55:54] <archivist_herron> drill out a bad bit and rivet in some new file and engrave to match
[08:55:57] <Jymmm> JT-Shop: Imagine custom made/cast awards, vest pins, MC embems, colors, etc
[08:56:50] <archivist_herron> imagine dial repair
http://www.collection.archivist.info/searchv13.php?searchstr=norfolk+dial
[09:05:36] <cradek> JT-Shop: yeah, just propane from a grill-sized tank
[09:07:13] <JT-Shop> ok, thanks
[09:07:41] <JT-Shop> what size crucible do you use?
[09:08:01] <JT-Shop> I see they are rated by A or B type and sizes
[11:04:27] <zeeshan> bobo i gave up for the night :P
[11:04:49] <jdh> wip
[11:04:51] <jdh> wimp
[11:05:31] <zeeshan> my enclosure is a wiring mess
[11:05:34] <zeeshan> on the i/o side
[11:05:36] <zeeshan> tons of wires
[11:05:36] <malcom2073> Bah! No quitting!
[11:06:34] <zeeshan> question of the day: i spin servo by hand, measure the voltage at the motor leads, i get +v in cw direction -v in ccw direction
[11:06:53] <zeeshan> also meaasure the tachometer leads and get +v cw , -v ccw
[11:07:10] <zeeshan> have i identified the + leads for both the tacho and the motor?
[11:07:20] <zeeshan> as long as they're the same , i should not have "run away"?
[11:08:10] <pcw_home> yes (typically they are subtracted at the summing junction an the drive input)
[11:08:25] <pcw_home> (but this is drive dependent)
[11:09:22] <pcw_home> commanded velocity and tachometer velocity are subtracted I should say
[11:09:41] <zeeshan> "The feedback element must be connected for negative feedback. This will cause a difference between the command signal and the feedback signal, called the error signal."
[11:09:55] <zeeshan> (from manual)
[11:10:40] <pcw_home> well connect tachometer and it will either runaway or not
[11:10:49] <zeeshan> haha im trying to avoid re-wiring it
[11:10:52] <zeeshan> caus eits a pain to swap the leads.
[11:11:21] <zeeshan> i have 2 things left
[11:11:39] <zeeshan> tacho wiring, motor lead wiring, and scale wiring (analog side)
[11:11:41] <zeeshan> i guess 3 things.
[11:11:43] <pcw_home> unless the drive specifies the analog input to output polarity you still have to test
[11:12:02] <zeeshan> the most annoying will be the scale wiring, cause each twisted pair has a shield, and then there is an external shiled around the whole set of twisted pairs
[11:12:48] <zeeshan> well it identies which leads o nthe drive out of motor a b c is motor + and motor -
[11:13:23] <zeeshan> motor a = motor -, and motor b = +
[11:14:37] <zeeshan> it also says tach - = tachomter input, tach+ = signal ground
[11:17:46] <pcw_home> so use their polarities, but expect runaways (dont couple linear motion initially
[11:17:58] <zeeshan> yes theyre off
[11:18:04] <zeeshan> also if i limit the current on the servo drive
[11:18:11] <zeeshan> it shouldnt be an aggressve jump right?
[11:18:15] <zeeshan> cause it wont have as much torque
[11:53:17] <tjtr33> zeeshan: all the old Baldor/Copley drives i used had tacho + connected to gnd, and tacho - connected to opamp input ( some filtering 1st but no inversion ).
[11:53:27] <tjtr33> This just depends on internal err circuit implementation.
[11:53:31] <tjtr33> I suggest connecting per mfctr on a bench, not to machine. use a battery box to verify motor and tacho polarities.
[11:56:23] <tjtr33> http://www.copleycontrols.com/motion/pdf/412.pdf
[12:00:48] <norias> howdy
[12:05:32] <norias> having trouble determining what motherboard to buy
[12:05:36] <norias> any suggestions?
[12:06:24] <jdh> software stepping or hardware?
[12:06:54] <tjtr33> or servo.then onsider isa/pci/ethernet
[12:06:55] <norias> software...
[12:07:03] <norias> so, more complete description
[12:07:14] <norias> i am replacing the controller in a commercial cnc
[12:07:32] <norias> it has brushed dc servos and amplifiers
[12:07:47] <norias> encoders, also
[12:08:03] <norias> planning on using mesa anything i/o boards
[12:09:13] <norias> everything that people have said is a good board for linuxcnc
[12:09:16] <norias> is unavailable
[12:09:21] <norias> (i.e. my info is old)
[12:11:15] <tjtr33> http://www.newegg.com/Product/Product.aspx?Item=N82E16813135339 i have no experience with it, but it has been mentioned as good for Linuxcnc
[12:11:47] <norias> for $60 I'll run with it
[12:11:53] <tjtr33> ECS CDC-I/D2550 v1.0 Intel Atom D2500 Intel NM10 Mini ITX Motherboard/CPU Combo
[12:11:59] <tjtr33> try to read about it
[12:13:40] <norias> i appreciate the suggestion
[12:13:42] <tjtr33> i always balk at single pcu slots, and go back to big old desktops w P4's and lots of slots
[12:13:49] <norias> hmm
[12:13:59] <norias> i don't think i'll need more than one slot
[12:14:01] <tjtr33> ^^ balking
[12:14:04] <zeeshan> lol thats so cheap
[12:14:05] <tjtr33> :)
[12:14:07] <norias> since this will be a single purpose machine
[12:14:17] <norias> i know! computers are so cheap!
[12:14:21] <norias> it's freakish
[12:14:41] <norias> makes me want to build a bunch of little computers
[12:14:47] <norias> special purpose
[12:14:53] <norias> a tv-watching computer
[12:14:54] <tjtr33> big town? friendly recycler? go in with a live cd and run tests
[12:14:56] <zeeshan> maybe i should use that motherboard
[12:14:58] <norias> and a music listening computer
[12:15:09] <zeeshan> there is no gfx card port!
[12:15:21] <zeeshan> i thought on board video caused jitter?
[12:15:32] <tjtr33> some not all
[12:15:44] <tjtr33> (hasnt testde all yet :)
[12:15:48] <norias> heh
[12:15:54] <norias> so... yeah, for $60 though
[12:15:59] <norias> I can give it a try
[12:16:14] <PCW> http://www.newegg.com/Product/Product.aspx?Item=N82E16813157565&cm_re=j1900_asrock-_-13-157-565-_-Product
[12:16:16] <PCW> about 2x faster if you have the space
[12:17:18] <PCW> atom d525s and d2xxxs's are slugs
[12:17:33] <malcom2073> mesa mesa mesa :P
[12:18:40] <malcom2073> oh you were talking about mesa, does having onboard video affect the jitter ina mesa based system?
[12:20:09] <norias> mesa
[12:20:32] <PCW> all jitter has effects (D525s that show <10 usec in latency test have 100 usec or more real latency)
[12:21:08] <tjtr33> thx PCW is there any more info on howto do real latency tests?
[12:21:23] <malcom2073> PCW: I thought the whole idea behind offloading the step clock onto the FPGA was that jitter wouldn't matter?
[12:21:27] <PCW> latency test only shows thread dispatch latency which is fine until you actually try to run code
[12:21:38] <tjtr33> so scope needed?
[12:21:56] <PCW> halscope will do
[12:22:03] <tjtr33> ok thx!
[12:22:18] <PCW> plot read times for example
[12:24:38] <norias> bah
[12:24:46] <zeeshan> http://www.cnczone.com/forums/linuxcnc-formerly-emc2-/155405-hardware-pulse-generation-questions.html
[12:24:47] <zeeshan> lol
[12:24:51] <PCW> malcom2073: in the step generator jitter is still an issue because the stepgen uses feedback
[12:24:51] <zeeshan> i somehow came to this link
[12:24:52] <PCW> (it samples the step generator position at the servo thread rate so it can close a feedback loop)
[12:25:02] <zeeshan> this guy called the 5i25 a fancy gpio board
[12:25:04] <zeeshan> =D
[12:25:32] <tjtr33> hmm, halscope has unit of 1 thread cycle. so run a 'fast' thread and look for regularity between cyclic reads?
[12:25:55] <tjtr33> like read of a hardware pin
[12:25:56] <malcom2073> Hmm, I guess I'll have to look into it a bit more, I misunderstood what the mesaboard could do for me I think heh
[12:26:01] <PCW> no, plot the read time (for example)
[12:27:24] <Tom_itx> zeeshan, it is pretty fancy
[12:27:32] <zeeshan> i know :P
[12:27:38] <zeeshan> but he was saying it in a "putting down" sense
[12:27:39] <tjtr33> the time stamps of reads? not understanding 'read time'
[12:27:42] <PCW> you can generate MHz steprates with the stepgen and there are ways to mitigate jitter (if you are running 2.6 or later you can remove most jitter with the DPLL module)
[12:28:43] <PCW> with the DPLL module its possible to get sampling jitter < 500 ns with real jitter in the 100s of usec region
[12:31:16] <PCW> normally this is not needed unless:
[12:31:18] <PCW> 1. You have a CPU with lousy jitter specs
[12:31:20] <PCW> 2. you are running Preemt-RT (like with hm2_eth)
[12:31:21] <PCW> 3. you have a very high performance step/dir system (100IPS or so) and have a small error budget
[12:33:28] <PCW> tjtr33: all hal functions have parameters for the time they take to run, and the maximum time, plotting these can be interesting
[12:33:45] <tjtr33> thx will look into that
[12:34:37] <PCW> you will find that the time to run major functions has much more jitter than indicated in the latency test...
[12:35:14] <PCW> (note that these times are in CPU clocks)
[12:35:38] <tjtr33> :) good soemthing that is invariate :)
[12:35:49] <tjtr33> cpu clock
[12:39:05] <PCW> well you _hope_ the CPU clock is invariant :-)
[12:41:23] <norias> oops
[12:41:27] <norias> missed all that
[12:42:54] <norias> so, sounds like PCW is expert here
[12:46:44] <norias> incidentally
[12:46:52] <norias> on these anything i/o mesa cards
[12:46:58] <norias> what lives on the fpga?
[12:48:17] <norias> i think i'm going with 7i33ta for my daughter card
[12:51:56] <tjtr33> got ttl encoders/scales?
[12:52:56] <norias> no idea
[12:53:01] <norias> not sure how to tell
[12:53:03] <norias> maybe
[12:53:14] <norias> time to learn about encoders
[12:53:24] <norias> oh! thats what ttl means!
[12:53:27] <norias> Time To Learn!
[12:53:54] <norias> bbiaf looking for part numbers on encoders
[12:54:02] <tjtr33> transistor to transistor logic aka 5V sqr wave
[12:56:22] <tjtr33> bbl back to remodeling
[13:00:40] <norias> half the companies that made parts for this machine
[13:00:49] <norias> have been acquired by other companies
[13:01:00] <norias> and almost every part is no longer manufactured / supported
[13:05:55] <gambakufu> anu reason why debian is the preferred dist for 2.6 over ubuntu?
[13:06:30] <norias> people who like cnc don't like stuff that looks pretty :)
[13:16:13] <PCW> probably unity pushed it over the edge
[13:17:17] <norias> so, crap
[13:17:25] <norias> how do i know if my encoder is ttl?
[13:17:48] <PCW> number of wires
[13:18:09] <PCW> rotary encoder?
[13:18:46] <PCW> (lots of older linear encoders are sine/cosine)
[13:19:00] <norias> rotary
[13:19:14] <norias> has ... a+ a- b+ b- z ...
[13:19:28] <PCW> differential then
[13:19:39] <norias> ahh, ok
[13:19:42] <norias> hmm
[13:19:53] <PCW> so 8 wires maybe with a shield
[13:20:04] <norias> so, what lives on the fpga in the mesa anything i/o cards?
[13:20:14] <norias> and mesa 7i33ta
[13:20:16] <PCW> depends :-)
[13:20:22] <norias> works with this kind of encoder?
[13:21:22] <PCW> thats an interface issue not a logic issue bu yes most of our enccoder interfaces can work with TTL or differential
[13:22:23] <PCW> you might look at the 7I77/5I25 combo, newer and cheaper than a 7I33TA/50 pin FPGA card/isolated IO card
[13:22:59] <norias> "our" ?
[13:23:03] <norias> do you work at mesa?
[13:23:08] <PCW> yes
[13:23:17] <norias> good deal. nice products
[13:23:20] <PCW> I'm the mesa shill
[13:23:22] <norias> from what i can tell
[13:23:37] <norias> so... what lives on the fpga?
[13:25:23] <PCW> well again it depends on the configuration, might bwe PWM gens and encoder counters or stepgens or serial interfaces or absolute encoder interface
[13:25:25] <PCW> plus a bus interface for the host connection
[13:25:52] <norias> so, i have to load the fpga
[13:25:58] <norias> or it comes with code on it?
[13:26:15] <PCW> bus interface might be localbus, PCI, SPI , Serial, Ethernet etc
[13:26:40] <norias> incidentally, what is your role at mesa?
[13:26:54] <norias> ( i know, i have lots of questions)
[13:27:03] <PCW> depends on card, some use on card flash, others are programmed when linuxcnc starts
[13:27:22] <PCW> Chief bottlewasher
[13:27:44] <JT-Shop> and sheep protector
[13:27:50] <norias> bbiaf
[13:27:53] <norias> boss calling
[13:45:38] <norias> back
[14:23:41] <norias> documentation is hard
[16:07:16] <Deejay> gn8
[17:04:36] <Computer_Barf> do you guys know of any company that makes all in one driver / steppers like these that offer a 570 oz in option?
[17:04:39] <Computer_Barf> http://motion.schneider-electric.com/products/mdrive/mdrive_plus_motion_control.php?nema=23
[17:06:53] <malcom2073> Computer_Barf: nema34 not an option?
[17:07:15] <malcom2073> Also, why?
[17:07:20] <Computer_Barf> not the best size for the x / y of the g0704
[17:09:16] <Computer_Barf> well I like that they are hybrid's with encoders, and I like the driver on the stepper rather than in a box
[17:12:26] <Computer_Barf> forgoing the three drivers in the electronics enclosure would save some space, and I like the idea of possibly adding water cooled heatsinks to their coolant enclosures
[17:12:52] <Computer_Barf> not to mention that coolant flying all over the place would likely wash over those enclosures
[17:13:05] <malcom2073> Wow that operating temp heh
[17:14:40] <Computer_Barf> oh well I don't know how hot they will get , it just seemed like putting something in a box that might get hot could be handled some other way
[17:15:53] <Computer_Barf> The Z axis is going to be nema 34
[17:16:20] <Computer_Barf> but its my understanding that they are too big for the x and y
[17:17:25] <PCW> Integrated drives have never been very popular (bad environment for electronics: heat, vibration, contamination very expensive if something goes wrong)
[17:18:12] <Computer_Barf> arnt you already risking that with the stepper?
[17:18:22] <PCW> nope
[17:18:49] <Computer_Barf> i mean, with flood all over the place Im already running the assumption that I need to enclose and seal it off
[17:18:54] <furrywolf> steppers are much less picky than electronics, especially about heat. steppers put out a lot of heat and don't mind being hot, while electronics fail very quickly at the temperature a stepper runs at...
[17:20:06] <PCW> on the other hand hybrid steppers should not run very hot, but there are reasons why integrated drives are rare
[17:20:37] <furrywolf> of course they should run hot. if they're not running hot, your drive current and/or voltage should be upped more. :)
[17:20:44] <norias> heh
[17:20:45] <malcom2073> lol
[17:20:52] <norias> my irc says "People are talking."
[17:20:55] <norias> I saw it as
[17:21:01] <norias> "People are attacking!"
[17:21:16] <Computer_Barf> you won't get the warning when that happens.
[17:21:19] <PCW> hybrid (with encoder) step motor dont run hot
[17:21:25] <norias> hmm
[17:21:33] <norias> you usually hear the rounds hitting stuff around you
[17:21:37] <PCW> (because they are full servos)
[17:21:48] <furrywolf> ah
[17:22:01] <furrywolf> I figured you meant hybrid, as in, hybrid permanent magnet and variable reluctance...
[17:22:10] <furrywolf> which is what most steppers these days are.
[17:22:24] <malcom2073> That actually reminds me a bit of SmartMotors
[17:22:26] <Computer_Barf> cool problem solved , where can I get 570 oz version. lol.
[17:22:33] <malcom2073> the mdrive
[17:25:21] <furrywolf> what's wrong with drivers in a box like everyone else?
[17:25:47] <norias> just be like everyone else!
[17:25:50] <norias> conform!
[17:26:04] <furrywolf> yes!
[17:26:40] <furrywolf> (says the furry kinky redneck commie hippie...)
[17:42:18] <JT-Shop> damn van won't start, battery is good... starter overhauled and new solenoid last month...
[17:43:20] <Computer_Barf> is it a white van?
[17:43:51] <JT-Shop> no
[17:44:10] <Computer_Barf> humm. I was thinking it maybe hasn't done enough raping lately
[17:45:05] <Tom_itx> take the mule instead
[17:45:19] <Computer_Barf> what about selling stolen goods out of the back of it
[17:45:23] <Computer_Barf> have you tried that?
[17:47:18] <Computer_Barf> there has to be more van stereotypes
[17:47:51] <Computer_Barf> are you just a working class kinda guy that needs his van working ready for work tomorrow?
[17:52:54] <zeeshan> JT-Shop: is it cranking at all
[17:54:27] <JT-Shop> no, just a click and the headlights don't dim but the dash lights dim when I try and start it
[17:54:52] <zeeshan> whats the battery voltage at
[17:54:54] <zeeshan> without cranking
[17:54:57] <JT-Shop> cleared the memory and tried both keys
[17:55:00] <JT-Shop> 12.8
[17:55:22] <JT-Shop> battery is new and load checked today
[17:55:33] <zeeshan> im thinking you have a bad ground somewhere
[17:55:41] <zeeshan> did you try wiggling the ground at the battery
[17:55:44] <zeeshan> to make sure its not loose
[17:56:05] <JT-Shop> headlights don't dim...
[17:56:39] <zeeshan> headlight ground takes a diff path
[17:56:42] <JT-Shop> I think a rat chewed some critical wire somewhere
[17:56:54] <zeeshan> starter ground share engine ground
[17:57:03] <zeeshan> id measure the resistance between starter body and negative battery temrinal
[17:57:13] <zeeshan> if that reads some ohms
[17:57:21] <zeeshan> its prolly the solenoid remote work
[17:57:22] <zeeshan> *wire
[17:57:25] <JT-Shop> LOL, I can't even find the starter on that damn sidways V6
[17:57:45] <zeeshan> transversely mounted?
[17:58:22] <JT-Shop> yes it is front wheel drive V6
[17:58:46] <zeeshan> if you cant see it, its prolly on the back side of the motor
[17:58:51] <zeeshan> near firewall towarsd the bottom
[17:59:03] <zeeshan> :/
[17:59:22] <JT-Shop> I'll have to jack it up after the sun comes back up and see if I can spot it
[17:59:26] <zeeshan> if it was easier to access, you could disconnect the remote solenoid wire
[17:59:37] <zeeshan> put voltmeter between that and battery ground
[17:59:40] <zeeshan> and see if it goes to 12v when you crank
[17:59:52] <zeeshan> if it doesnt, then at least you can isolate what is wrong
[18:00:01] <JT-Shop> what is a "remote" solenoid wire?
[18:00:35] <zeeshan> starter has 3 terminals, 2 big ones. big wire comes directly from battery (usually unfused), and ground
[18:00:51] <zeeshan> there is a smaller terminal, like about 10 gauge or 12 gauge wire that activates the solenoid
[18:00:57] <zeeshan> when you crank
[18:01:06] <JT-Shop> yea, I'm familiar with most starters
[18:01:52] <zeeshan> http://www.2carpros.com/forum/automotive_pictures/266999_starter_3.jpg
[18:01:53] <JT-Shop> I thought you meant something like a "remote" starter
[18:01:53] <zeeshan> term s
[18:01:57] <zeeshan> nahh
[18:02:13] <JT-Shop> yea, I know what a starter solenoid looks like
[18:02:19] <zeeshan> i know!
[18:02:22] <zeeshan> but im a visual person :P
[18:02:51] <JT-Shop> I just don't see this one from the top even with a bunch of stuff taken off
[18:03:07] <zeeshan> is it a GM?
[18:03:31] <JT-Shop> chevy yea
[18:03:33] <JT-Shop> uplander
[18:03:36] <JT-Shop> POS
[18:03:37] <zeeshan> year?
[18:03:38] <zeeshan> haha
[18:03:46] <JT-Shop> 2007
[18:03:47] <zeeshan> i have manuals till 2006
[18:03:49] <zeeshan> AW
[18:03:50] <zeeshan> damn
[18:03:55] <zeeshan> 2006
[18:04:01] <zeeshan> 2006 is prolly similar
[18:04:14] <JT-Shop> yea, I'd guess it is the same
[18:04:22] <zeeshan> http://ww2.justanswer.com/uploads/tracker40/2011-10-22_165848_1.gif
[18:04:31] <zeeshan> haha they placed it under the exhaust manifold
[18:04:42] <zeeshan> is your exhaust mani towards firewall
[18:04:43] <zeeshan> or rad
[18:04:49] <JT-Shop> which one the front or back one
[18:05:04] <zeeshan> er v6.
[18:05:12] <zeeshan> where is the serpentine
[18:05:13] <zeeshan> driver or passenger
[18:05:19] <JT-Shop> ok, I know where it is now
[18:05:33] <JT-Shop> on the front
[18:05:36] <zeeshan> nice!!
[18:05:38] <JT-Shop> thanks for that link
[18:05:41] <zeeshan> you can prolly access it from the top
[18:05:49] * zeeshan hates getting under cars
[18:06:06] <malcom2073> zeeshan: Don't you have a project car in your garage?
[18:06:11] <JT-Shop> I might be able to see it with a mirror
[18:06:13] <zeeshan> yes malcom2073
[18:06:15] <malcom2073> I seem to recall a car that looked half disassembled from a pic of your mill
[18:06:31] <zeeshan> oh its pretty disassembled haha
[18:06:50] * JT-Shop doesn't need any more projects LOL
[18:06:53] <malcom2073> heh
[18:06:55] <zeeshan> me either man
[18:06:59] <zeeshan> i wanted to build a 3d printer
[18:07:05] <zeeshan> making my fiance do it.
[18:07:30] <JT-Shop> lol
[18:09:23] <JT-Shop> if it wasn't so close to lazy time I'd get suited up and go look for the damn starter
[18:11:25] <malcom2073> lol
[18:11:42] <malcom2073> I don't think I could convince my wife to build a 3d printer
[18:12:05] <malcom2073> She tolerates my hobbies, even encourages them, but stays far from partaking in them :P
[18:12:51] <JT-Shop> zeeshan, that photo just makes my day! thanks again
[18:17:24] * JT-Shop wanders inside to make some jambalaya
[18:21:56] <malcom2073> yum
[18:24:09] <_methods> jymmbalaya?
[18:36:07] <furrywolf> you have a fiance that can build things? *jealous*
[18:45:46] <furrywolf> bbl, errands
[18:49:19] <XXCoder> yay home
[18:49:26] <XXCoder> working while still sick SUCKS
[18:49:35] <XXCoder> I can add gross stuff after "sucks"
[18:49:48] <XXCoder> lots

[20:23:21] <_methods> damn we ran pete off
[20:56:18] <malcom2073> Man just doesn't know how to handle a good jymmmbalaya
[20:57:51] <XXCoder> jy mmmm
[20:59:58] <zeeshan> man i have a little bit of wiring left
[21:00:10] <zeeshan> anyone who wires HEIDENHAIN gas scales before
[21:00:20] <zeeshan> glass scales. holy cow theyre a PAIN
[21:00:47] <zeeshan> just the 3 scales and its ready to be powered up
[21:01:38] <zeeshan> http://c1.staticflickr.com/9/8682/16242463226_90f574cd37_h.jpg http://c4.staticflickr.com/8/7480/16082519967_8e2e4ad967_h.jpg http://c4.staticflickr.com/8/7471/16081023790_ea7e9061b0_h.jpg
[21:01:42] <CaptHindsight> zeeshan: HEIDENHAIN "gas" scales? Are you measuring pressure or flow rate?
[21:01:51] <zeeshan> CaptHindsight: typo
[21:01:56] <CaptHindsight> :)
[21:02:00] <zeeshan> i stopped caring about my wiring
[21:02:29] <malcom2073> Damn heh
[21:02:31] <malcom2073> lotta stuff
[21:02:37] <CaptHindsight> you can clean it up after it's all working
[21:03:12] <zeeshan> i think the only thing i dont like so far without firing this thing up
[21:03:18] <zeeshan> is there a 3 AWG wire running right next to my modbus wires.
[21:03:20] <malcom2073> Then spend another two days getting it working after the cleanup :)
[21:03:25] <zeeshan> haha malcom2073
[21:03:30] <zeeshan> if it works, it can stay messy!
[21:03:40] <zeeshan> the main place its a messis at the +24vdc distribution block
[21:03:42] <zeeshan> -24vdc
[21:03:57] <CaptHindsight> what motherboard is that?
[21:04:05] <zeeshan> asus k7v400
[21:04:27] <zeeshan> er
[21:04:30] <zeeshan> a7v400mx
[21:05:01] <zeeshan> i stopped using it because the ethernet port died on it
[21:05:07] * zeeshan is using wireless
[21:05:18] <zeeshan> i might replace it wit hthat celeron one pcw posted if it gives me issues inthe future
[21:10:26] <zeeshan> its quiet here tonight
[21:10:43] <zeeshan> np jt!
[21:34:51] <Sairon> oi
[22:21:38] <RyanS> anyone know a bit about propane burners? i built this
http://i210.photobucket.com/albums/bb176/Mingzhus/venturi_zpsb4108e8f.jpg test fired it. the flame is huge. not sure what effect various shape nozzles have
[22:23:59] * furrywolf is still waiting for it to load. hasn't even started the image yet.
[22:24:45] <furrywolf> I hate photobucket.
[22:26:12] <Rab> furrywolf, you might like this browser extension:
https://github.com/Owyn/HandyImage
[22:26:34] <furrywolf> yay, after five minutes of loading javascript and bloat, five seconds to download a simple lineart image.
[22:26:35] <furrywolf> I hate photobucket.
[22:26:35] <Rab> I don't see any PB/Flickr/etc garbage any more, it just displays the image at full res.
[22:27:06] <furrywolf> rab: or I can just stick to my rule of ignoring everyone who pastes links to those services.
[22:28:09] <furrywolf> ryans: so you're asking how to make it focused, like a torch? I think they have cylindrical rather than tapered designs...
[22:28:23] <furrywolf> or maybe even tapering the other direction
[22:30:45] <RyanS> well its for a forge and it seems pretty much any shape would work ok, but idk
[22:31:11] <furrywolf> then a huge flame sounds just fine. :)
[22:31:26] <SpeedEvil> RyanS: are you mixing air with it ?
[22:31:38] <SpeedEvil> RyanS: or is it just a massive propane nozzle
[22:31:45] <furrywolf> yes, it's a venturi design.
[22:32:03] <furrywolf> doesn't mean he has the orifice size, pressure, etc right, of course...
[22:32:12] <SpeedEvil> Orifice size is important.
[22:32:33] <furrywolf> tell me about it! some toys are too small, some too large...
[22:33:01] <RyanS> i just copied these dimensions
http://www.duncanshearer.co.nz/kilnplans/burners/venturi/venturi%20burner-01.jpg
[22:33:32] <RyanS> orrifice is an 0.8mm mig tip
[22:33:37] <SpeedEvil> Does the flame properly retain at the flame retention hole?
[22:33:53] <SpeedEvil> I need to make my boosted propane burner.
[22:33:56] <furrywolf> is it a nice blue flame with yellow tips, or a big orange flame?
[22:34:12] <SpeedEvil> With a ~1000C or so electric pre-heater
[22:34:34] <furrywolf> why electric? heh
[22:34:55] <RyanS> ive only tested with no nozzle but the flames blue
[22:35:24] <SpeedEvil> furrywolf: gas in principle would work too - but then you need to seperate out the flows and have a heat exchanger
[22:35:38] <SpeedEvil> What do you mea by 'with no nozzle'
[22:36:02] <furrywolf> use a regenerative design... you pass the incoming mixture around the outside of the flame.
[22:36:13] <furrywolf> the simplest is a coiled copper tube the flame aims through
[22:37:00] <SpeedEvil> furrywolf: copper may have obvious issues
[22:37:16] <furrywolf> I've seen copper, but stainless might be better if you're going for really hot.
[22:37:32] <RyanS> hmm it doesn't have a flame retention nozzle right now
[22:37:36] <SpeedEvil> For a small - ~8kW or so burner - electric seems easier
[22:38:05] <SpeedEvil> RyanS: you need it - the flame retention device acts as an orifice to make the output gas go lots faster
[22:39:10] <furrywolf> http://i203.photobucket.com/albums/aa124/rangerssteamtoys/IMG_1012.jpg like that, but less kludgey. :P
[22:39:14] <RyanS> this design perhaps?
http://www.selas.com/product?id=76
[22:40:08] <SpeedEvil> RyanS: your design had one already
[22:40:10] <SpeedEvil> just make ti
[22:40:12] <SpeedEvil> it
[22:43:15] <RyanS> this nozzle seems ok
https://www.youtube.com/watch?feature=player_detailpage&v=qtCkIf8TZhU#t=47
[22:45:03] <RyanS> brb
[22:45:19] <furrywolf> http://www.alloyavenue.com/vb/showthread.php?2468-Newbie-with-a-moya-burner that looks... safe
[22:49:22] <furrywolf> fun, at least. :P
[22:51:34] <unfy> bought aluminum to make gantry, re-looked at the auto band saw cutter thing here at work.... yeah, i'll be cutting things by hand
[22:51:47] * unfy is always amazed at how this building can fuck up tools ._.
[22:52:22] <XXCoder> fun
[22:52:26] <furrywolf> lol
[22:52:37] * furrywolf somehow doubts it's the building fucking up the tools
[22:53:06] <unfy> heh
[22:53:29] <unfy> i did once take a bunch of pics and pasted them online once, but realized that such things may cause problems so i deleted them
[22:53:33] <unfy> many folks weeped with me
[22:53:45] <RyanS> mines unnecessarily over-engineered. ill post a pic of it burning in a min
[22:55:10] <furrywolf> there's no kill like overkill.
[22:55:31] <[cube]> i'll be building one of those pretty soon
[22:55:36] <[cube]> for a little forge
[22:55:57] <RyanS> i looove over engineers
[22:56:08] <RyanS> engineering
[22:56:16] <[cube]> going to have a hook up for forced air from compressor, with regulator
[22:56:19] <[cube]> just for added boost
[22:56:23] <[cube]> mostly when getting it up to temp
[22:57:17] <RyanS> hmm i dont think forced air is nescessary
[22:58:38] <[cube]> it definitely isnt :)
[22:58:47] <[cube]> but i just think it'll be fun to build it in
[22:59:06] <[cube]> i'll probably go a different route than aboe
[22:59:09] <RyanS> why not i say
[22:59:20] <[cube]> and have a separate inlet for the air
[22:59:39] <[cube]> maybe spiral it up the forge column
[22:59:54] <[cube]> to enhance that cyclonish effect
[23:01:36] <RyanS> i don't even know what to do with a forge, I just thought it was a cool thing to build
[23:01:49] <RyanS> or hot :p
[23:03:20] <[cube]> hehe
[23:03:28] <[cube]> i plan tot just cast aluminum parts
[23:03:32] <[cube]> and clean up on mill
[23:03:41] <[cube]> maybe try some copper
[23:03:53] <furrywolf> I'd like to try casting someday, but I have way more projects than time or money.
[23:03:58] <[cube]> got all the materials, just need a weekend to set asaide
[23:04:12] <[cube]> hard in winter
[23:04:23] <furrywolf> you can cast copper with no furnace... just make copper thermite. :P
[23:04:57] <[cube]> lol
[23:06:45] <RyanS> http://picpaste.com/pics/venturi_burner-OJg5dQvk.1421124345.JPG
[23:08:28] <furrywolf> shiny
[23:08:38] <RyanS> http://picpaste.com/pics/venturi_burner2-fi7Rqeo5.1421124474.JPG
[23:09:43] <furrywolf> turn up your input pressure. :)
[23:10:27] <RyanS> yeah i think thats 15psi
[23:12:38] <RyanS> do you think centre hole area needs the angle? that'd be a pain to machine
http://www.selas.com/product?id=76
[23:12:47] <Computer_Barf> what are you going to use the propane burner for?
[23:13:04] <RyanS> forge
[23:13:41] <Computer_Barf> I always have too many projects but
[23:13:52] <Computer_Barf> i would like to build a multi fuel burner
[23:14:11] <Computer_Barf> and a large aluminum tilft furnace
[23:14:38] <RyanS> its bored in two parts and welded
[23:14:48] <Computer_Barf> and then a plastic pyrolysis / catalytic cracking unit for distilling kerosene from plastic
[23:16:34] <Computer_Barf> so basically waste polyethelene , polyproplene could be used as a feedstock to produce a fuel source for melting aluminum , cast iron, copper alloys.
[23:16:53] <SpeedEvil> Computer_Barf: too much hastle IMO - stripping out the PVC 100% reliably
[23:17:16] <furrywolf> pvc burns just fine?
[23:17:37] <Computer_Barf> you could build a venturi scrubber with a reaction chamber to deal with chlorine
[23:17:40] <SpeedEvil> Yes, and creates really nasty stuff in the output
[23:17:58] <RyanS> big nozzle for short bushy flame?
[23:18:18] <Computer_Barf> furrywolf: yeah incomplete combustion would produce dioxin , and pvc will always create a bunch of chlorine
[23:19:09] <Computer_Barf> but you can bond the chlorine to something to capture it, but you would want to make sure you are doing really complete combustion
[23:19:56] <Computer_Barf> I think for post consumer food containers you could avoid pvc
[23:21:08] <CaptHindsight> http://www.ijacsr.com/IJACSR_Vol.%201,%20NO.%202,%20March%202013/Production%20of%20Aromatic%20Hydrocarbons%20%20Related%20Kerosene%20Fuel%20from%20Polystyrene%20and%20Polypropylene%20Waste%20%20Plastics%20Mixture%20using%20Fractional%20Distillation%20Process.pdf
[23:21:11] <Computer_Barf> SpeedEvil: you were thinking dioxins? or chlorine?
[23:21:39] <SpeedEvil> yes
[23:21:44] <SpeedEvil> chlorine is an irritant
[23:21:54] <Computer_Barf> capture it.
[23:22:01] <SpeedEvil> dioxins very much aren't
[23:22:12] <Computer_Barf> well its irritating to get cancer
[23:22:19] <Computer_Barf> flol
[23:22:54] <CaptHindsight> "In this process polypropylene and polystyrene waste plastic to kerosene production percentage was only 17% "
[23:23:02] <furrywolf> don't you just need to get the dioxins hotter?
[23:23:24] <Computer_Barf> poystyrene would mostly create waxes
[23:23:38] <Computer_Barf> you would have to crack it alot with polystyrene
[23:24:01] <CaptHindsight> http://www.ijmer.com/papers/Vol2_Issue4/BJ2421682173.pdf
[23:24:06] <SpeedEvil> furrywolf: yes - in principle it's doable - the problem is that to actually reliably stop production of nasties, you need process control and involved stuff
[23:24:14] <furrywolf> I remember an article a couple years back about some company that managed to tweak the process to get a high percentage from electric arc pyrolysis..
[23:24:23] <CaptHindsight> Conventional Fuel Generated from Polypropylene (PP) Waste Plastic like Kerosene/Jet/ Aviation Grade with Activated Carbon
[23:24:26] <Computer_Barf> plus just by nature polystyrene is usually a foam.
[23:24:34] <SpeedEvil> Computer_Barf: err - no
[23:24:41] <SpeedEvil> polystyrene is an ordinary polymer
[23:24:44] <Computer_Barf> i mean why bother with polystyrene when you can get hdpe waste by the ton fairly cheap
[23:24:52] <SpeedEvil> it's just it's commonly used in a expanded form
[23:25:16] <CaptHindsight> "production yield percentage are third fraction liquid fuel or aviation/kerosene/jet category fuel yield is
[23:25:16] <CaptHindsight> 30.40%, other fraction fuel percentage was 62.60% light gas 3% and black carbon residue 4%."
[23:25:31] <Sairon> eh, process control
[23:25:35] <Sairon> who cares
[23:25:35] <SpeedEvil> Or actual barrels of crude - $50
[23:25:47] <Computer_Barf> CaptHindsight: its a matter of cracking ,
[23:26:07] <SpeedEvil> Arc pyrolysis is interesting
[23:26:12] <Sairon> fracking cracking
[23:26:16] <Sairon> it's all the same
[23:26:28] <Computer_Barf> its.. actually quite diffrent.
[23:26:34] <Sairon> lol
[23:27:00] <[cube]> just printed a little spindle 'wrench' for my mill
[23:27:01] <[cube]> http://i.imgur.com/AM4TKWZ.jpg
[23:27:04] <[cube]> works great hehe
[23:27:27] * furrywolf prefers wrenches to be metal, preferably drop forged
[23:27:28] <Computer_Barf> cube what mill
[23:27:34] <[cube]> milling machine
[23:27:43] <Computer_Barf> i mean.. what kind
[23:27:48] <[cube]> oh
[23:27:52] <[cube]> its a chinese noname
[23:27:59] <[cube]> somethign you'd find at harbor freight
[23:28:04] <[cube]> but mine's a candian brand
[23:28:07] <Computer_Barf> X2?
[23:28:10] <[cube]> *Canadian
[23:28:25] <[cube]> no its a round column...
[23:28:27] <[cube]> cheaper one
[23:28:28] <Computer_Barf> g0704 here
[23:28:31] <[cube]> lemme find pic
[23:29:19] <Computer_Barf> SpeedEvil: what was the err no in response to?
[23:30:07] <furrywolf> bbl, wolfy bedtime
[23:30:19] <Computer_Barf> Capthindsight: you can find a surprising number of people online who've built their own cracking machines
[23:30:55] <[cube]> Computer_Barf:

[23:30:57] <[cube]> similar to that
[23:31:09] <Computer_Barf> whoever it was with the propane burner, it looks nice, did you turn it on a lathe?
[23:31:24] <CaptHindsight> unfortunately (or fortunately) I'm not looking for any :)
[23:33:46] <RyanS> Computer_Barf in two sections and then welded togther
[23:34:53] <Computer_Barf> add a wvo/kerosene addition to it.
[23:35:01] <Sairon> hmm
[23:35:10] <Sairon> why would people have their own cracking machines?
[23:35:26] <XXCoder> cracking machines?
[23:35:30] <Computer_Barf> They have access to waste plastic
[23:35:38] <Computer_Barf> and want free fuel
[23:35:43] <Sairon> oh. ok
[23:35:55] <XXCoder> ah plastic to fuel
[23:36:10] <Sairon> seems wastefull somehow
[23:36:26] <Computer_Barf> to break it back down into the oil it was made from
[23:36:34] <XXCoder> if person goes to dump and grabs em?
[23:36:36] <XXCoder> dunno
[23:36:56] <Computer_Barf> wasteful compared to sealing it in a hermetic landfill ?
[23:37:24] <Computer_Barf> shit some day we'll be mining it anways.
[23:37:41] <XXCoder> yeah once we got perfect recycler
[23:37:49] <XXCoder> or even mass to energy conversion
[23:38:03] <XXCoder> once we also has other way, its perfect anything to anything machine
[23:38:05] <Computer_Barf> well I am talking about a mass to energy conversion.
[23:38:27] <Sairon> we briefly attempted to use recovered plastics
[23:38:31] <Sairon> in a product
[23:39:42] <Computer_Barf> yeah, it seems more realistic to break plastic back down, crack it into ethylene and propene , and then synthesize the plastic over again. Waste plastic can only be recycled so much before the contaminants start wasting batches
[23:40:10] <XXCoder> barf or just don't bother since scientists has direct method to turn algae to oil
[23:40:13] <XXCoder> crude oil even
[23:40:23] <XXCoder> but still havent fgured mass scale
[23:41:01] <Computer_Barf> scientists also have a way to make carbon nanotubes and buckyballs but commercial viability is an entirely diffrent animal
[23:41:18] <Sairon> oh, don't i know that
[23:41:27] <Computer_Barf> Im suggesting small scale, distrubuted reactors for waste plastic energy recovery
[23:41:27] <Sairon> my life for the past five years
[23:41:35] <Sairon> has been moving something from the lab
[23:41:40] <Sairon> to commercially viable
[23:41:44] <Sairon> nightmares
[23:42:28] <Computer_Barf> don't get me wrong, I've got a small filament extruder I've built for my 3d printer, its just recycled feedstocks are limited by practical useability
[23:43:11] <Sairon> hmm
[23:43:19] <Sairon> filament extruder hard to make?
[23:43:43] <Computer_Barf> I probably spent about 200 hours on it
[23:43:58] <Computer_Barf> my biggest limitations was my ability to work metal efficiently
[23:44:05] <Sairon> oh
[23:44:14] <Sairon> i do ok with metal
[23:44:28] <Sairon> and i've got 600 lbs of polypropylene injection molding stock
[23:44:28] <Computer_Barf> I wanted to be able to make a bunch of them , which ment that the way I made the first one wasn't going to happen
[23:44:30] <Sairon> in my basement
[23:44:52] <Sairon> maybe i should be making filament
[23:45:31] <Computer_Barf> I mean, there was stainless steel parts , flanges, nozzel, etc. I got myself a mill and am cncing it
[23:46:08] <Computer_Barf> I'll need to get a lathe or add a 4th axis too
[23:46:09] <Sairon> heat at the nozzel
[23:46:18] <Sairon> or is it heat all through the feed barrel?
[23:46:41] <Computer_Barf> no if you feed the entire feed barrel I't will likely jam
[23:46:49] <Computer_Barf> well , depends on the motor
[23:47:13] <SpeedEvil> Computer_Barf: 'by nature polystyrene is usually a foam' - it's not
[23:47:15] <Sairon> i mean
[23:47:20] <Sairon> where does it get heated?
[23:47:25] <SpeedEvil> It's just a normal polymer - if a bit shitty in its properties.
[23:47:34] <SpeedEvil> So its most common use is as a foam
[23:47:35] <Computer_Barf> its small scale so its not really oriented around how you would normally do injection moulding
[23:47:46] <Sairon> ok
[23:47:50] <Computer_Barf> sairon: it has a heat block right before the nozzel
[23:47:56] <Computer_Barf> here let me see if I have some stuff on this computer
[23:48:34] <Computer_Barf> http://i.imgur.com/dsCR538.png
[23:49:01] <Computer_Barf> that was an early design, much stuff got added for the pulling / cooling / spooling
[23:49:40] <Computer_Barf> http://i.imgur.com/zSEuJDb.png
[23:49:54] <Computer_Barf> that was a bit later but that water bath failed
[23:50:26] <Sairon> so you have to keep that hopper going hardcore
[23:52:01] <Computer_Barf> well my goal is to have something less hefty than russ's filament extruder, but around same performance. You can do a 2.2 kg spool in about 30 something minutes
[23:52:08] <Computer_Barf> so its not THAT fast
[23:52:28] <Computer_Barf> but its not like many of the other ones you see out there where your running all day for a few spools
[23:53:33] <Computer_Barf> what I want next is to build a small hammer mill
[23:54:08] <Computer_Barf> something big enough to load a 2 liter pet bottle into
[23:54:44] <Sairon> oh, hmm
[23:54:55] <Sairon> no one uses PP in 3d printing?
[23:55:16] <Computer_Barf> yes and no
[23:55:31] <Computer_Barf> ive not found ppl selling spools of it
[23:55:56] <Computer_Barf> but ive seen a larger style than normal extruder extruding it in a thick bead to make a large vase
[23:56:23] <Computer_Barf> and I know that the laywood product is a mixture of sawdust in the proper mesh size, mixed with PP
[23:57:00] <Computer_Barf> Locally I've got my hands on abs pellets , and polycarbonate pellets
[23:57:21] <[cube]> what's the best media to work with holding oil?
[23:57:33] <[cube]> for example way oil
[23:57:35] <Computer_Barf> and ive chopped up PET and printed with it , but doing all that work is a pain in the ass, hence the hammer mill idea
[23:57:42] <[cube]> i figured nylon would be ideal
[23:58:18] <Computer_Barf> cube are you asking this in context to what we were talking about or just in general?
[23:58:26] <[cube]> i recently tried printing an 'oil distribution' part out of PLA
[23:58:34] <[cube]> it worked fine...
[23:58:42] <[cube]> but theoild eventual seeped right through
[23:58:52] <Computer_Barf> through the layers?
[23:58:54] <[cube]> yeah
[23:58:57] <[cube]> the integrity of the part is still fine
[23:59:12] <[cube]> just strange to see the oil totally infiltrate and seep throught he pla
[23:59:25] <Computer_Barf> well , pla will melt in the presence of DCM , but its nasty stuff
[23:59:33] <Computer_Barf> diachloromethane
[23:59:55] <Computer_Barf> or chloroform
