[02:32:47] <ganzuul> allo
[04:51:24] <XXCoder> heys
[04:54:23] <Contract_Pilot1> Morning
[04:56:33] <Contract_Pilot1> http://www.walmart.com/ip/46945879 Looks like they are out of stock now glad i orderd 4 haha now lets see if they ship hahah
[04:57:46] <Praesmeodymium> they were ou in like 15 minutes on all 4 of the similar deals
[04:57:59] <Praesmeodymium> from when they showed up in here anyway
[04:59:22] <XXCoder> wtf crapmart sells steppers?
[04:59:40] <Wolf_Mill> marketplace
[04:59:49] <XXCoder> ah that seems popular lately.
[05:01:06] <Contract_Pilot1> Yea, market place but your get walmat buyer protection
[05:01:50] <Contract_Pilot1> http://www.walmart.com/ip/46914656
[05:02:01] <Contract_Pilot1> 6.00 for a 48V PS
[05:02:24] <Contract_Pilot1> Prob sell a thousand cheap from a over run or somthing
[05:02:56] <Contract_Pilot1> Or just real china prices
[05:07:42] <XXCoder> lemme see aliexpress prices
[05:07:55] <XXCoder> nema 24??
[05:08:03] <XXCoder> that may be reason why its so cheap lol
[05:09:16] <XXCoder> http://www.aliexpress.com/item/4-MB450A-4-2A-Stepper-Driver-4-Nema-23-Stepper-Motor-112mm-3KG-cm-4-lines/1468146879.html
[05:10:22] <Contract_Pilot1> 57HS5630A4 Motor & MB450A Driver
[05:10:34] <XXCoder> cheapest one I found (no driver) http://www.aliexpress.com/item/0-45N-M-NEMA-23-Stepper-Motor/32365657531.html
[05:11:29] <Contract_Pilot1> https://translate.google.com/translate?sl=zh-CN&tl=en&js=y&prev=_t&hl=en&ie=UTF-8&u=http%3A%2F%2Fsumtorelec.com%2Fproduct.asp%3Fplt%3D10%26Pone%3D1%26Ptwo%3D10%26Pthree%3D0%26Pfour%3D0%23&edit-text=
[05:11:56] <Contract_Pilot1> Ali express inflates the shipping deal on ali direct and get better prices
[05:12:13] <Contract_Pilot1> Just have to know how do biz with china
[05:12:50] <XXCoder> odd, that site has no N.M
[05:12:58] <Contract_Pilot1> Have a customs bond and a freight forwarder.
[05:14:15] <XXCoder> what N.M power is needed to run a large router for exampke
[05:14:17] <XXCoder> 4'x8'
[05:15:20] <Contract_Pilot1> http://www.convertunits.com/from/oz-in/to/N-m
[05:16:59] <XXCoder> weird
[05:17:09] <XXCoder> Xorg restarted
[05:20:14] <XXCoder> anyway conversion dont help when I dont know much power is needed :)
[05:21:52] <Contract_Pilot1> Not sure how much is needed
[05:22:00] <XXCoder> np
[05:22:13] <Contract_Pilot1> Have you searched similar routers
[05:22:14] <XXCoder> I got parallel port today whoohoo
[05:22:25] <XXCoder> so I can finally connect my small cnc router to my pc soon
[05:23:40] <Contract_Pilot1> Another path pilot sucess https://www.youtube.com/watch?v=ZgU57Zdec9I
[05:23:43] <Wolf_Mill> I finally bothered to hook up my relay pack so now I have coolant and auto spindle shutdown :)
[05:25:17] <Contract_Pilot1> Since i will have 3 eatra motors if walmart ships i may build a small router..
[05:25:46] <Contract_Pilot1> I have some eztra acme screw arround
[05:26:02] <XXCoder> since you has 4 you could play around with 4th axis
[05:26:09] <XXCoder> it dont seem to be complex
[05:26:10] <Wolf_Mill> I should have jumped on them walmart motors as well, I could have sold this x1 as a ready to run thing
[05:26:29] <Contract_Pilot1> 'hahaha
[05:27:27] <XXCoder> even at buck each I am not about to order from walmart anytime soon.
[05:28:42] <Contract_Pilot1> Support walmart junkies and retards need a place to work.
[05:29:28] <Contract_Pilot1> Coffee is not doing well this morning
[05:46:13] <MattyMatt> XXCoder, did you get a 2 port one? worth the extra $2 imo
[05:46:44] <XXCoder> 2 port? yeah I wasn't looking for that but it come 2 ports
[05:46:47] <XXCoder> why though?
[05:46:54] <MattyMatt> more pins
[05:47:00] <MattyMatt> more axis
[05:47:20] <XXCoder> nice, it will be useful in future
[05:47:22] <Jymmm> more flavor
[05:47:23] <Wolf_Mill> ^ moar pins are good...
[05:47:26] <Jymmm> more fun
[05:47:29] <malcom2073> Moar axis!
[05:47:29] <XXCoder> right now using el cheapo chinese controller
[05:47:37] <XXCoder> only 3 axis
[05:48:16] <MattyMatt> I got 4 axis, but yeah that fits nicely on one port, but it leaves none for playing with quadrature encoders etc
[05:48:59] <XXCoder> I had a silly idea for cnc
[05:49:15] <Jymmm> XXCoder: rubber bands and silly string?
[05:49:18] <XXCoder> x axis y axis and C
[05:49:36] <XXCoder> actually no
[05:49:51] <XXCoder> an axis (either x or y), Z and C
[05:49:57] <MattyMatt> x+y+c = vinyl cutter
[05:50:13] <MattyMatt> with a Z solenoid too
[05:50:18] <Contract_Pilot1> man Ak parts sales suck this week
[05:50:57] <MattyMatt> AK? 7.62mm?
[05:51:03] <Contract_Pilot1> Yea,
[05:51:30] <MattyMatt> invent AK-48. innovate or die
[05:51:44] <MattyMatt> anyone ever done a twin barrel one?
[05:52:10] <Contract_Pilot1> Not sure what would be the point?
[05:52:48] <MattyMatt> it'd be like a face with a squint
[05:52:52] <Contract_Pilot1> Was at 7-11 somone see my carry piece what is that? Where can i get one? I daid you cant i made it!
[05:52:59] <Contract_Pilot1> ahhh said
[05:53:28] <Jymmm> MattyMatt: https://www.youtube.com/watch?v=tmrggqzwhFc
[05:54:04] <Contract_Pilot> Even AK steel mags at 11.00ea are not selling
[05:54:36] <XXCoder> not enough people hunting wabbits.
[05:54:38] <MattyMatt> start a local insurrection
[05:54:45] <XXCoder> war sells
[05:54:53] <Contract_Pilot> hahaha
[05:54:56] <XXCoder> or new obama taking guns rumor round
[05:55:23] * Jymmm paints bullseyes on MattyMatt car, house, butt, etc
[05:55:57] <MattyMatt> please. I'm sure I have all those things somewhere
[05:56:01] <XXCoder> put bulleye target on bulleye target
[05:56:12] <XXCoder> so guy can hit center and hit center too.
[05:56:39] <MattyMatt> pimp my deathstick
[05:58:08] <MattyMatt> AK on a segway
[05:59:12] <XXCoder> new recrusive AK, so you can shoot while you shoot while...
[05:59:13] <Contract_Pilot> I sent a low ball 40.00 they agreed www.ebay.com/itm/271968689926 will make a nice PS for my G0704 conversion.
[06:00:08] <MattyMatt> chunky
[06:00:16] <Contract_Pilot> Mesa money almost gone... have 2.5 more weeks till they instock.
[06:01:05] <MattyMatt> fruit machine psu are about that spec
[06:01:38] <Contract_Pilot> fruit machine?
[06:01:55] <Contract_Pilot> They selling homo's in vending machines now?
[06:01:57] <MattyMatt> coin slot gambling thingy
[06:02:19] <Wolf_Mill> hmm, I might have to get one of them 48v psu as well...
[06:04:53] <Jymmm> Too bad it doesn't have 220V primary
[06:05:24] <malcom2073> Heh, I love make an offer on ebay
[06:05:38] <XXCoder> "I offer you lack of murder for your item"
[06:07:30] <MattyMatt> half my kingdom and my eldest daughter's hand
[06:08:32] <MattyMatt> you can have the half of nowt now, and the rest when I get round to making some
[06:09:22] <Contract_Pilot> http://www.stevenrhine.com/wp-content/uploads/2015/09/PSU-Ebay.jpg
[06:10:04] <Contract_Pilot> 40.00 is a steel cannot make one for that price..
[06:10:11] <Contract_Pilot> and that is shipped.
[06:14:01] <Contract_Pilot> http://www.amazon.com/ELPAC-BFS500-48-125V-AC-48-4V-DC-D506889/dp/B013IQYVKC
[06:15:55] <Contract_Pilot> DB Knock out punches are spendy.
[06:17:40] <Contract_Pilot> http://www.stevenrhine.com/wp-content/uploads/2014/11/driverack-inside.jpg
[06:19:40] <fenn> 3 separate psu's is kinda dumb, as they can't support each other during peak loads
[06:21:55] <Contract_Pilot> Each PSU is for each Driver
[06:22:19] <Contract_Pilot> 5A each driver
[06:22:33] <Contract_Pilot> Only 2 Are in Use.
[06:23:49] <Contract_Pilot> PMDX will be removed and replaced with a 7I76 http://www.stevenrhine.com/wp-content/uploads/2014/11/100_3992-1024x575.jpg
[06:24:51] <Contract_Pilot> I think I will scrap the rack and make my own enclosure
[06:29:23] <fenn> hmm i might get one of those $6 PSU's but won't be surprised if it turns out to be a 12V PSU instead of 48V
[06:36:23] <ganzuul> Bought a cordless screwdriver for 6 euro. New.
[06:39:29] <Contract_Pilot> We will see it may be 4.8V hahaha
[06:39:39] <Contract_Pilot> at .1A
[06:40:06] <Contract_Pilot> Or orders may not get processed!
[06:40:11] <MattyMatt> or 220V at 13A, until the diode blows
[06:40:42] <MattyMatt> hell yeah, just get drivers that are 240V ready
[06:40:57] * MattyMatt looks, they are called vfd
[06:41:53] <fenn> well they probably didn't make up the 1232g shipping weight
[06:42:16] <MattyMatt> vexta do stepper drivers with built in psu. spendy tho
[06:42:34] <fenn> how do you even ship a kilogram from china for $6
[06:43:12] <MattyMatt> by shipping 1m kg for $6m
[06:43:44] <MattyMatt> 1m kg = 30 containers?
[06:45:11] <MattyMatt> presumably those silly container ships can't all be at the 30 ton limit, but you can ship a lot of 1kg on one ship
[06:47:40] <MattyMatt> these pacific atolls should build giant rafts and take the country mobile when the seas rise
[06:48:02] <MattyMatt> donate oil drums here
[06:48:26] <Contract_Pilot> I ahve been to tarawa many many times
[08:16:02] <enleth> ah crap. TIR up to 0.41mm on spindle, the lower bearings must be shot too
[08:21:00] <Sync> wat enleth
[08:24:12] <enleth> that was my reaction too
[08:24:49] <enleth> but it's not the shitty chinese toolholder that I suspected at first
[08:25:40] <enleth> I can feel the wobble when I press a fingernail into the spindle taper wall on low speed
[08:26:17] <enleth> (yep, that's how I check for runout when I can't be arsed to get the indicator)
[08:26:39] <enleth> so I got the indicator and it wasn't pretty
[08:29:27] <enleth> well maybe it's the taper, but I can't see how
[08:30:04] <enleth> I's not wobbling at an angle, the tool points straight down
[08:31:14] <enleth> but its axis is offset from the rotation axis
[08:40:24] <Sync> yeah
[08:40:40] <Sync> it is either the bearings or somebody messed up the spindle big time
[08:42:51] <malcom2073> Damn that sucks
[08:53:06] <Wolf_Mill> http://i.imgur.com/v68lNrg.jpg
[08:55:07] <malcom2073> oooo pretty
[08:55:47] <_methods> damn you got that motor fast
[08:55:52] <_methods> didn't you just order it?
[08:56:13] <Wolf_Mill> yup, shipped from NJ, like 3hrs from here
[08:56:54] <archivist> enleth, if it had had a big crash a bent spindle like in my old horizontal mill
[08:58:10] <archivist> chuck a parallel bar and see if the tir varies with distance
[09:03:12] <Wolf_Mill> ha this should be fun, magnetic halls effect sensor for the speed control
[09:05:32] <archivist> is that an ac servo?
[09:05:59] <malcom2073> Sewing machine? Probably a universal motor and a SCR?
[09:06:06] <anomynous> irssi seems to have users still
[09:06:23] <archivist> because on ac servo the hall effect is also for commutation
[09:06:52] <archivist> cant read the label
[09:09:29] <enleth> archivist: if it does, it's bent. if it doesn't, the bearings are fucked. correct?
[09:10:22] <archivist> you should also feel roughness from bearings, else yes
[09:11:08] <enleth> well the problem is, they feel quite smooth. the upper bearing was rather crunchy but I replaced it.
[09:11:18] <archivist> I did see a cyclic error form a bearing where I assumed is had a large/small roller/ball
[09:12:14] <archivist> that shows up as the tir not being in the same place each rev
[09:12:19] <Wolf_Mill> its a AC servo, 4 wire to the motor and 5 wire hall pickups, and 3 wire to the pedal lever that has a magnet on a stick and a hall in it
[09:14:27] <anomynous> what is the hall effect? It sounds like important and interesting
[09:14:37] <fenn> enleth maybe you didn't preload the bearings correctly and it's just loose
[09:15:33] <archivist> anomynous, a semiconductor that is affected/senses magnetic field
[09:16:31] <anomynous> a sensor called hall something, or its just how that specific type of servos use for position detecting?
[09:16:57] <Jymmm> anomynous: It's that hall monitor kid in school that would nark you off
[09:17:08] <anomynous> really?
[09:17:23] <archivist> https://en.wikipedia.org/wiki/Hall_effect
[09:17:27] <anomynous> thanks ;)
[09:17:40] <anomynous> i already believed Jymmm. Thanks for correciting
[09:17:44] <Jymmm> https://en.wikipedia.org/wiki/Hall_effect_sensor
[09:18:09] <Jymmm> anomynous: https://www.sparkfun.com/products/9312
[09:18:45] <Wolf_Mill> http://i.imgur.com/CyNObxX.jpg
[09:18:58] <fenn> my sarcasm detector is on the fritz or something
[09:19:18] <anomynous> not sarcasm. Just humour
[09:19:47] <anomynous> well. yes. sarcasm. Not cynical sarcasm ;)
[09:20:05] <Jymmm> anomynous: See, we spammed the internetz just to punk you on hall effect... it really is that damn kid
[09:20:13] <anomynous> got me ;)
[09:20:39] <enleth> fenn: this is a possibility, I did not touch the lower bearings at all but the spindle nose can be screwed all the way in with no gap
[09:22:02] <enleth> fenn: the manual suggests replacing preload spacers if that happens but I wonder if an additional spacer can be added between the nose cap and the lower bearing.
[09:24:08] <enleth> oh, there is one more thing. the bearings had "v" marks lightly scratched on the outer race, pointing towards the other bearing, that looks a bit like witness marks that are supposed to be present on matched bearings
[09:24:25] <enleth> but those marks were not aligned
[09:25:40] <enleth> however, I could not twist the bearings
[09:26:52] <skunkworks> Wolf_Mill, how are they controlling it? some sort of hall also?
[09:28:27] <Wolf_Mill> skunkworks: yup, hall chip in that box in the top of the pic
[09:28:50] <skunkworks> how are you planning on controlling it?
[09:29:10] <skunkworks> This is the ebay sewing machine drive/motor combo?
[09:29:49] <Wolf_Mill> yeah, 750w ac servo motor from ebay
[09:30:33] <enleth> the one that was advertised as quiet when not running?
[09:36:56] <Wolf_Mill> that was a joke sorta, commercial sewing machines either use servo motors or a constant running motor w/ a pedal activated clutch
[09:42:10] <skunkworks> Wolf_Mill, are you milling in the background?
[09:43:12] <CaptHindsight> toy robot arm https://www.kickstarter.com/projects/dobot/dobot-robotic-arm-for-everyone-arduino-and-open-so?ref=category
[09:44:41] <Wolf_Mill> I was, till the damn chips built up andtriggered my limit switch
[09:45:28] <skunkworks> yeck
[09:46:02] <CaptHindsight> toy robot arm for 1/2 the price http://www.ebay.com/itm/DIY-4-Axis-Servos-Control-Palletizing-Robot-Arm-Model-for-Arduino-UNO-MEGA2560-/351150915118
[09:47:12] <malcom2073> CaptHindsight: But that one doens't say Arduino, or kickstarter
[09:47:15] <malcom2073> that's worth at least $100
[09:47:19] <malcom2073> extra
[09:48:21] <CaptHindsight> heh well it actually has Arduino in the description
[09:48:31] <malcom2073> ah true, I missed that
[09:49:18] <CaptHindsight> a 6-axis for less with Arduino in the description http://www.ebay.com/itm/DIY-6-Axis-Servo-Control-Palletizing-Robot-Arm-Model-for-Arduino-UNO-MEGA2560-R3-/121642966422
[09:49:29] <malcom2073> Well, the KS one uses steppers, not hobby servos
[09:49:52] <malcom2073> But tbh, for an arm that small, do you need that much power?
[09:51:08] <CaptHindsight> heh EEG control
[09:51:24] <CaptHindsight> Obey and worship me
[09:52:04] <malcom2073> Heh
[09:52:59] <lair82> pcw_home You around?
[09:53:43] <Wolf_Mill> ok, now that I have the mill back up and running, the speed control. I'm gonna hook the scope up to it and see what the pedal is putting out, then see if I can trick it somehow :)
[09:55:48] <pcw_home> lair82: Yes
[09:56:35] <lair82> Hey pcw, I was going to ask for the link to sserial firmware update, but I just found the files in my thumb drive.
[09:58:04] <pcw_home> there were a few recent fixes to the scripts so you might want to refetch the sserial.zip file from Mesa
[09:58:32] <lair82> I had to rebuild my machine that was the first one to be done 3 years ago, I finally got rid of the faulty HDD and put a new SSD in it, and now I am getting faults that the firmware is out of date on my 7i70, 7i71, and 7i73
[09:58:52] <lair82> Do you have the the link handy?
[09:59:15] <pcw_home> http://www.mesanet.com/software/parallel/sserial.zip
[09:59:31] <lair82> Thank You sir
[09:59:54] <pcw_home> in linuxcnc/utils ( read the README file )
[10:08:03] <Wolf_Mill> pcw_home: the spindleX thing, that should work on this sewing motor box right? got 5v at the hall, 2.2v to start moving, 1.2v wide open...
[10:08:34] <pcw_home> for a spindle?
[10:08:43] <Wolf_Mill> yeah
[10:09:03] <pcw_home> is it reversable somehow?
[10:09:27] <Wolf_Mill> maybe...
[10:10:55] <Wolf_Mill> I might need to contact the seller for that tho... but it says it can do rev via pedal (hall sensor)
[10:12:23] <pcw_home> is the original speed control a variable voltage?
[10:14:37] <Wolf_Mill> ? http://i.imgur.com/CyNObxX.jpg
[10:15:21] <Sync> you could probably use our controller
[10:17:36] <malcom2073> Wolf_Mill: What voltage/current does that need?
[10:18:19] <ganzuul> blargh
[10:18:28] <Wolf_Mill> which part?
[10:18:31] <malcom2073> Wolf_Mill: The motor
[10:18:39] <Wolf_Mill> 110v
[10:18:40] <ganzuul> 10 thou cuts is taking forever to get down to size.
[10:18:46] <Wolf_Mill> 8A
[10:18:47] <malcom2073> Not the controller
[10:19:01] <ganzuul> 9797282
[10:19:02] <malcom2073> Hmm, I have a 80V/8A Elmo controller that may work
[10:19:06] <ganzuul> bleh
[10:19:09] <Wolf_Mill> no idea lol
[10:19:39] <malcom2073> Well, my dad does. They're super cheap though, he may be willing to part with it. Takes all sorts of inputs, step and direction, voltage for rpm, serial,
[10:19:52] <malcom2073> You'd need a 80VDC power supply though
[10:20:26] <automata__> hi pcw_home
[10:21:46] <malcom2073> You using this for your spindle?
[10:22:20] <Wolf_Mill> 200v ac
[10:23:06] <malcom2073> Ahh, nevermind
[10:23:30] <Wolf_Mill> yeah spindle :)
[10:25:11] <malcom2073> Maybe just get a VFD
[10:26:21] <Wolf_Mill> well, i only need rev if i'm tapping right?
[10:26:50] <malcom2073> Correct, and you'll be able to set rev close enough for normal machining ops with a VFD
[10:27:14] <malcom2073> Infact, you can probably just slap an encoder on the motor if you want to do rigid tapping with it
[10:28:05] <Wolf_Mill> or encoder on the spindle?
[10:28:14] <malcom2073> Or that if it's easier
[10:29:15] <Wolf_Mill> ordered the hightorque head, so I have a big empty box with the spindle inthe middle, no gears :)
[10:29:25] <malcom2073> Nice
[10:29:34] <Sync> you will also need the low end torque in the motor
[10:30:12] <_methods> https://www.kickstarter.com/projects/skarp/the-skarp-laser-razor-21st-century-shaving
[10:30:19] <_methods> kickstarter you make me lol so hard
[10:30:33] <_methods> 10,000 morons
[10:30:40] <_methods> and $2mil
[10:30:45] <Sync> well, at least kickstarter makes money
[10:30:53] <chris_99> someone mentioned in another channel you could use a laser galvanometer for super fast shaving ;)
[10:31:03] <chris_99> *mirror galvo
[10:31:29] <_methods> a glowin hot metal pan will work too
[10:31:34] <chris_99> heh
[10:31:39] <_methods> might leave some residual burning/scarring
[10:50:08] <ganzuul> \o/
[10:50:27] * ganzuul found a good way to get lots of stock removal on the 7x lathe!
[10:51:03] <pcw_home> Leave the chuck too loose?
[10:51:35] <ganzuul> Turn the tool upside down, dig straight in with the crossfeed. I'm using the parting tool for this to chip away just less than half its width at a time.
[10:51:48] <ganzuul> Oh, and of course run the lathe in reverse.
[10:52:44] <ganzuul> Need earplugs though. It make a very loud whistling noise.
[10:53:51] <ganzuul> It leaves a very rough cut, but it's fast.
[10:54:09] <ganzuul> And no issue with self-feeding or danger of running into the jaws.
[10:57:17] <CaptHindsight> mount this on the robot arm for "laser face milling" https://www.kickstarter.com/projects/skarp/the-skarp-laser-razor-21st-century-shaving?ref=category
[10:57:35] <ganzuul> I should get this cordelss screwdriver to actuate the crossfeed somehow... Would leave me a hand free to apply coolant.
[10:58:15] <ganzuul> "No razor burn"
[10:58:18] <ganzuul> ahhuh...
[10:58:33] <CaptHindsight> laser burn
[11:04:20] <Tom_itx> Wolf_Mill, you got that thing hacked yet? i see you already voided the warranty....
[11:05:27] <Wolf_Mill> basic spin is easy
[11:05:39] <Wolf_Mill> getting it to rev, might be little harder
[11:09:54] <Wolf_Mill> yay moar parts http://i.imgur.com/IyFTeVm.jpg
[11:10:32] <ganzuul> \o/ x2
[11:10:39] <ganzuul> Ghetto power feed works!
[11:11:26] <ganzuul> Even has a feedstop. Handle bolt comes loose.
[11:12:20] <Tom_itx> Wolf_, is that the motor?
[11:13:08] <enleth> ganzuul: isn't a whistling noise on a lathe just a sign that your stock is rubbing over a flat on the cutter?
[11:14:45] <archivist> whistle is tool chatter
[11:16:11] <archivist> as distinct to the lower groan when the stock and chuck vibrate
[11:19:43] <Wolf_Mill> Tom_itx: nope, thats a big ass air cylinder
[11:20:09] <Tom_itx> oh for tool changer?
[11:20:22] <Wolf_Mill> yup, 3" w/ 3/4" stroke
[11:22:47] <ganzuul> It's a very high pitch noise...
[11:23:32] <ganzuul> The tool is only approximately centered, so that could be a reason.
[11:26:46] <ganzuul> Otherwise this method is very undramatic. Just very fast stock removal. Enen faster with the screwdriver turning the handle.
[11:29:35] <ganzuul> Oh, and IPA evaporating quickly the mess is just clean chips.
[11:49:27] <ganzuul> Huh.
[11:49:38] <ganzuul> Coolant isn't keeping up.
[11:50:19] <ganzuul> I got this garden mister/sprayer that SpeedEvil suggested. But I suspect spraying IPA with it is asking for trouble.
[11:52:28] <SpeedEvil> gwaaaan.
[11:52:36] <SpeedEvil> More sanely.
[11:52:47] <SpeedEvil> If you cut it with water, then it is lots less flammable
[11:53:20] <SpeedEvil> If you arrange it so it is just squirting out a little stream - not a spray - as it does under low pressure too
[11:53:22] <ganzuul> I'm sure I can find a way to set water on fire.
[11:53:43] <ganzuul> I'll try!
[11:55:40] <SpeedEvil> cut lithium.
[11:57:27] <ganzuul> Might need a smaller diam nozzle...
[11:58:35] <ganzuul> Then again my shop vac does handle wet stuff too...
[12:25:08] <tiwake> herm
[12:25:15] <tiwake> I need to figure out what inserts I have
[12:25:33] <tiwake> also, I cant find the box of extra inserts for this
[12:25:35] <tiwake> bah
[12:31:51] <tiwake> ah here they are
[12:34:37] <tiwake> http://www.ebay.com/itm/10-x-KOMET-W29-34010-047930-BK-7930-NEU-/160894177317
[12:34:48] <tiwake> thats the inserts I have, looking for a bigger radius
[12:39:51] <CaptHindsight> ganzuul: you just need the right tap water https://www.youtube.com/watch?v=4LBjSXWQRV8
[12:54:24] <tiwake> so I can make a smaller hole
[12:54:55] <tiwake> (with an insert drill)
[12:57:06] <anomynous> hand up who likes to mill or drill dry rather than use coolant
[12:57:43] <archivist> depends what you are drilling/milling, brass is always dry
[12:57:48] <anomynous> steel
[12:58:09] <anomynous> or anything you can do dry, really ;D
[12:58:22] <archivist> and also for some metals depends on cutter material
[12:58:41] <tiwake> if you go slow enough you dont need coolant
[12:58:48] <tiwake> except for titanium :-x
[12:59:01] <anomynous> or if you go fast enough you break your inserts with coolant
[12:59:05] <archivist> eg you can crack your carbide tools with poor cooling, it is better dry then
[12:59:10] <ganzuul> SpeedEvil: Not sure if water is the best coolant on cast iron... I WD40ed the lathe from the toolpost down now.
[13:00:15] <anomynous> not just poor cooling, but just flood cooling and thermal shock
[13:00:59] <anomynous> well... thermal shock isnt an issue in manual mill i think ;D usually... but id hate to get water sprayed all over
[13:01:00] <anomynous> :(
[13:03:32] <ganzuul> Might be very effective with a smaller nozzle. Shouldn't be too hard to do that.
[13:03:35] <anomynous> i dont know why i brought this up but sandvik altogether recommends against using coolant in roughing :€ And picking up a dry part is just so much nicer
[13:04:39] <archivist> carbide can handle heat but not rapid cooling
[13:05:44] <tiwake> herm
[13:06:28] <tiwake> how to measure how deep a (really) bad surface is
[13:07:14] <archivist> a surface roughness meter
[13:07:17] <tiwake> need something pointy
[13:07:34] <archivist> it has a diamond stylus
[13:07:50] <tiwake> archivist: using an insert drill, its digging into the surface of the hole a fair amount in some places
[13:08:31] <tiwake> I dont think its too much, but I need to know if 0.007" will cover it
[13:08:40] <anomynous> archivist, youre right. Carbide can take heat ;D https://www.youtube.com/watch?v=V-nX4iky9oQ
[13:08:44] <tiwake> cause after the drilling we ream the hole
[13:08:53] <tiwake> the ream needs to clean it up
[13:09:19] <tiwake> I dont have a surface roughness tester
[13:10:18] <archivist> I might drill in more stages to get closer to a reaming size
[13:11:12] <tiwake> its a production job, doing 600 of these in an order, maybe 6 or so orders a year
[13:12:04] <tiwake> 4-6
[13:12:06] <tiwake> hmm
[13:12:08] <archivist> I can understand wanting to go from roughing to ream but I think you may be pushing your luck
[13:12:22] <tiwake> enh
[13:12:42] <tiwake> the hole diameter is +-0.002"
[13:13:00] <tiwake> so its not really critical
[13:14:10] <tiwake> for a reamer anyway
[13:14:21] <tiwake> 1.502" +-0.002"
[13:15:29] <maxcnc> hi is it posibel to grep in a UserDefind Mcode the axis.0.pos-relativ
[13:17:21] <maxcnc> i woudt like to make a pyvcp button that set the G10 L20 P1 X half
[13:17:55] <maxcnc> half the amount the pos-relativ showes
[13:19:47] <Loetmichel> carbide tools can take heat up to the temperature where the sinter "glue" metal melts (IIRC usually nickel)
[13:20:14] <Loetmichel> i used 1/8" shank mill bits pretty much to red hot
[13:20:23] <Loetmichel> without any dullness afterwards
[13:20:33] <Loetmichel> tungsten carbide of course
[13:21:50] <Loetmichel> and i managed to weld one of the carbide shafts to a cast steel vice once...
[13:21:52] <anomynous> cbn turning is fun to watch ;D
[13:22:09] <anomynous> how did you do that
[13:23:08] <Loetmichel> at 24krpm moving the shaft sideways into the vice is bad. and the steppers simply stopped, exerting pressure but not breaking it... took longer to press esc than the mill bot to be white hot
[13:23:22] <Loetmichel> and then after esc weld to the vice as it cools down ;)
[13:23:42] <tiwake> heh
[13:23:45] <anomynous> did you leave it for decoration?
[13:23:56] <tiwake> the hall of fame shelf
[13:24:01] <Loetmichel> sadly the vice dont exist anymore
[13:24:09] <Loetmichel> but i would have kept it
[13:24:09] <tiwake> I should do that
[13:24:28] <tiwake> set up a shelf for a hall of fame crashes
[13:24:46] <Loetmichel> it even embedded itseld a good 2mm deep in the side of the vice
[13:25:21] <Loetmichel> not "cutting" the steel but "welding" its way thru ;)
[13:27:16] <anomynous> i mismeasured a toroid mill and slow-rapided into vice. Boss ordered another one of the mills, but another one took the tool and borked it right after :(
[13:27:59] <Loetmichel> hrhr
[13:28:14] <tiwake> Loetmichel: where I used to work, somebody managed to friction weld a drill collet to the collet of the lathe
[13:28:24] <Loetmichel> ouch
[13:28:41] <tiwake> it was a pretty good weld too... heh
[13:28:48] <Loetmichel> that was an expensive error, wasnt it?`
[13:28:55] <tiwake> uh
[13:29:35] <Loetmichel> to be honest i was surprised that you could friction weld a TC bit to cast steel at all.
[13:29:52] <Loetmichel> with arc or autogen welding thats NOT possible...
[13:29:54] <tiwake> I think they used a sledge hammer to knock it off, and massaged it into usable condition
[13:30:09] <Loetmichel> tiwake: really?
[13:30:19] <Loetmichel> what do you do there? precision micron parts?
[13:30:34] <tiwake> cut the face of the collet back
[13:31:08] <tiwake> Loetmichel: no, it was this place http://www.bigskyprecision.com/
[13:31:42] <Loetmichel> ahm yeah
[13:32:05] <Loetmichel> hopefully i never fly a plane that was build with these "precision" parts then
[13:32:19] <tiwake> the parts are pretty good really
[13:32:41] <Loetmichel> hitting anything thats mounted on the main spindle of a "standard size" lathe with a sledgehammer is a nono
[13:32:51] <Loetmichel> if you dont want to buy a new main shaft afterwards
[13:33:06] <tiwake> oh, no... they took the collet out of the machine before sledgehammer
[13:33:07] <tiwake> heh
[13:33:12] <Loetmichel> ah, ok
[13:33:22] <tiwake> yeah, that would have been even dumber
[13:33:52] <tiwake> my lathe on the other hand
[13:33:57] <tiwake> I dont think it would blink
[13:34:23] <tiwake> its a big beefy lathe, it would take a lot to screw with how its set
[13:35:02] <Loetmichel> i met a lathe worker once that made new "diazed 63A" fuse inserts for his main motor out of steel on his lathe because "the ceramic ones blow all the time!"
[13:35:20] <Loetmichel> ... the lathe was a 4 meters diameter vertical one
[13:35:47] <Loetmichel> <- had to replace the 192kW motor afterwars
[13:35:50] <Loetmichel> +d
[13:36:17] <Loetmichel> i think that is right in the "precision work" department for that monster ;)
[13:36:43] <Loetmichel> THERE you could and would use a sledgehammer to tighten and loosen some mounting screws
[13:37:03] <Loetmichel> but on any reasonable sized lather i wouldnt use a hammer at all
[13:37:21] <tiwake> my machine weighs something like 13-14,000lbs
[13:37:27] <Loetmichel> other than a copper/lead one to push workpieces gently into positoion
[13:38:09] <Loetmichel> thats on the big side of "reasonably sized" but still in it in my book ;)
[13:38:45] <Loetmichel> thats only about 6-7 metric tons, isnt it?
[13:38:57] <tiwake> enh, could be, it would depend on length, which in my case is shortish
[13:39:41] <tiwake> its about 16" of travel to the font of the collet from home position
[13:40:00] <ganzuul> My machine weights 43,000 grams...
[13:41:13] <anomynous> ganzuul, psst. Use mg to get a bigger number. They lose.
[13:41:25] <Loetmichel> i was talking about these: http://hellwig-gmbh.de/wp-content/uploads/2010/02/K-5002.jpg
[13:41:54] <tiwake> Loetmichel: thats cheating, its not a lathe
[13:41:54] <anomynous> thats a big lathe
[13:42:10] <Loetmichel> tiwake: it is
[13:42:24] <tiwake> its one of those turn table milling things
[13:42:28] <Loetmichel> the lower person is standing ont the "chuck"
[13:42:33] <Loetmichel> yeah
[13:42:44] <Loetmichel> but not milling
[13:42:46] <Loetmichel> tunrning
[13:42:57] <tiwake> hmm
[13:43:21] <tiwake> I'll settle with a hybrid :-x
[13:43:36] <Loetmichel> https://www.youtube.com/watch?v=5ZnpgEdJbrU
[13:43:38] <Loetmichel> like this
[13:44:07] <Loetmichel> its a pure pathe
[13:44:09] <Loetmichel> lathe
[13:44:49] <tiwake> meh, fine
[13:44:54] <Loetmichel> ganzuul: my small one only weights 13000 gramm ;)
[13:45:00] <Loetmichel> (C0)
[13:45:45] <Loetmichel> and my mill is even lighter ;)
[14:08:04] <MattyMatt> the one the girlfriend was tied to in Deja Vu just had a toolpost. no active tooling gantry
[14:14:41] <MattyMatt> was it Face Off? I can't find the scene in Deja Vu
[14:25:00] <ganzuul> Loetmichel: I'm upgrading my SC3. Getting a 1 inch wider saddle and a 5 inch indepenedent 4 jaw chuck. Next, an oversized QCTP and a mod to lower it, so I can use 16mm toolbits.
[14:25:26] <ganzuul> That way, when I move on to the next size lathe I'll be able to bring a lot of my old tooling with me.
[14:27:55] <tiwake> alright, got some inserts ordered
[14:49:37] <_methods> VTL
[14:49:48] <_methods> big VTL
[14:50:19] <archivist> where?
[14:50:23] <archivist> gimme
[14:50:31] <_methods> Loetmichel pic earlier
[14:50:52] <_methods> http://hellwig-gmbh.de/wp-content/uploads/2010/02/K-5002.jpg
[14:52:05] <archivist> I walked by one about that size some years ago at a factory that made tunnel boring machines
[14:52:20] <archivist> all gone now
[14:52:30] <_methods> http://www.camcomachine.com/images/MORANDO1_VTL.JPG
[14:53:23] <archivist> got the CMM a bit further today, got it to calibrate the probe
[14:53:36] <_methods> ah nice you got it to get past the homing error
[14:53:42] <archivist> pc dmis is junk though
[14:53:43] <_methods> what was causing it to not home out
[14:54:00] <_methods> well unfortunately the cmm world is full of bad software
[14:54:03] <archivist> the probe has to be in contact first!
[14:54:11] <_methods> ahhh
[14:54:22] <_methods> contact with what?
[14:54:38] <archivist> its contacts seem a bit iffy
[14:54:54] <_methods> it just has to have a probe in the probe head?
[14:55:46] <archivist> just a simple contact type probe so if its contacts are open the software refuses to home
[14:56:30] <archivist> wiggle the probe stylus end and it came to life
[14:56:42] <renesis> archivist: this is the 'free probe?
[14:56:44] <_methods> weird so it won't home until it thinks it's hit something lol
[14:56:49] <renesis> *'free'
[14:56:53] <archivist> renesis, yes
[14:57:06] <renesis> that sucks
[14:57:19] <archivist> _methods, no, it has to be shorted (not hitting)
[14:57:20] <renesis> tho makes sense
[14:57:28] <_methods> oh well that makes more sense
[14:57:33] <archivist> dirty contacts
[14:57:47] <_methods> ok that's much more better
[14:58:11] <archivist> might dismember the probe and clean inside soon
[14:59:24] <archivist> improvised a datum sphere today and made a right angle stylus adapter to get it something to calibrate onto
[15:08:45] <archivist> my other option is to make an adapter and fit the other probe I have
[15:59:43] <MrSunshine> hmm any diff in how much a countersunk screw can take compared to a cap head screw ?
[16:00:11] <ganzuul> How much torque?
[16:00:16] <Jymmm> MrSunshine: how much your toquring it down to?
[16:00:52] <MrSunshine> or something .. i need to fasten a chuck on the lathe, easier to make a deep coutner sink compared to making a hole for a cap head
[16:00:56] <ganzuul> hmmm... Sharp corners are stressy-points, right?
[16:01:30] <ganzuul> Fracture points... What's it called?
[16:02:35] <Jymmm> Is it common to smell "something" in a wood stove when the fire is almost dead? This is the stove I have http://www.homedepot.com/p/US-Stove-2-000-sq-ft-EPA-Certified-Wood-Burning-Stove-2000/202815104
[16:03:14] <Jymmm> I dont see any smoke, but I DO smell something like how a campfire smells when it's just smoldering.
[16:03:39] <MrSunshine> if the fire is almost dead i guess it will still smell
[16:03:47] <ganzuul> Might need to get your chimney de-sooted.
[16:03:51] <MrSunshine> as long as something is burning
[16:04:15] <Jymmm> It was so strong at a point that I got a headache and re-opened the windows/doors
[16:04:51] <Jymmm> ganzuul: is that a guess?
[16:04:59] <Jymmm> ganzuul: or personal experiance?
[16:05:31] <Jymmm> There is a gasket around the door, and I don't smell anythign when the fire was hot.
[16:05:56] <ganzuul> Educated guess. Limited experience from growing up in a house which saw a lot of wood stove heating in the winters. - The walls of the chimney should be still hot, causing an updraft. Soot buildup will constrain airflow and refract heat.
[16:06:26] <ganzuul> Also, the soot can catch fire and release carbon monoxide.
[16:06:27] <Jymmm> ganzuul: Right, I am aware of needing a hot stove pipe
[16:06:46] <Wolf_Mill> or lack of heat is letting air draft back down
[16:06:48] <ganzuul> Carbon monoxide, AFAIK, causes headaches.
[16:06:54] <ganzuul> And death.
[16:07:11] <Jymmm> ganzuul: There is a CO monitor behind the stove
[16:07:12] <ganzuul> And memory loss.
[16:07:21] <ganzuul> Is it working?
[16:07:22] <Jymmm> ganzuul: huh? whoa r yoou?
[16:07:35] <Jymmm> ganzuul: it blinks green every 90 seconds
[16:08:01] <ganzuul> Does it need regular maintenance?
[16:08:36] <Jymmm> Wolf_Mill: But the stove pipe was hot from the 2hr burn before, you think it would cool down enough that it would down draft?
[16:09:24] <Jymmm> Wolf_Mill: I would think any warm/hot pipe and the residual heat from the firebrick would keep the stovepipe hot enough to prevent that.
[16:09:49] <Wolf_Mill> probably not
[16:10:18] <Jymmm> Wolf_Mill: You have a wood stove?
[16:10:28] <Wolf_Mill> a couple
[16:10:45] <Jymmm> Wolf_Mill: And it never smells at the end of a burn?
[16:11:14] <Jymmm> ...when it's just smoldering
[16:11:22] <Wolf_Mill> mine are about 400lbs of steel plate
[16:11:42] <Jymmm> Wolf_Mill: This is mine http://www.homedepot.com/p/US-Stove-2-000-sq-ft-EPA-Certified-Wood-Burning-Stove-2000/202815104
[16:12:53] <Wolf_Mill> oo 21" log...
[16:13:08] <Deejay> gn8
[16:13:19] * ganzuul tucks Deejay in
[16:13:30] <Wolf_Mill> yeah, they dont hold heat very long, and newer stove pipe really doesnt hold heat
[16:13:34] * Jymmm ducttapes Deejay
[16:13:58] <Deejay> stop that ;)
[16:14:01] <XXCoder> zeeshan|2: you need to caption your videos :)
[16:14:04] <Jymmm> Wolf_Mill: Well, I would think 100F should still hve an updraft
[16:14:11] <XXCoder> I have couple resources if you want to.
[16:14:21] <Wolf_Mill> fire brick is also just to keep you from killing the stove
[16:14:43] <Wolf_Mill> depends on how sealed the house it
[16:14:47] <Wolf_Mill> it/is
[16:14:50] * Deejay falls asleep now. cya tomorrow, gents
[16:15:01] <Jymmm> Wolf_Mill: And it never smells at the end of a burn; when it's just smoldering
[16:15:05] <Jymmm> ??
[16:15:10] <Jymmm> Wolf_Mill: yours that is
[16:15:21] <Wolf_Mill> sometimes
[16:15:24] <XXCoder> zeeshan|2: autocaptions of you speaking seems.. qyite accurate at times so edit should be pretty fast.
[16:15:54] <Jymmm> Wolf_Mill: How long does it last for (ballpark) ?
[16:15:58] <Jymmm> the smell
[16:16:16] <Wolf_Mill> but mine is in a one level garage thats sealed tight as a screen door
[16:16:59] <Jymmm> lol
[16:17:14] <Wolf_Mill> other is at my moms house, it will smoke the house up if you let it get too far down
[16:17:37] <Jymmm> Wolf_Mill: is Moms' stove sealed?
[16:17:37] <Wolf_Mill> due to warm air leaking out of the house, woodstove is in the basement
[16:17:49] <Wolf_Mill> na we dont have that epa BS
[16:17:54] <Jymmm> lol
[16:18:21] <Jymmm> Wolf_Mill: Just a 55gal drum and some reclaimed asbestose pipe?
[16:18:23] <Wolf_Mill> usually just crack the basement door open to get the draft back up in the right direction
[16:18:40] <Wolf_Mill> sierra woodstove
[16:19:50] * Jymmm goes to find a tophat, brush, and ladder
[16:26:39] <Wolf_Mill> air leaks, clothes drier, gas fired water heater all can cause neg pressure in teh house, same thing that caused propane/nat gas tankless hotwater heaters to freeze up in the winter

[17:19:49] <PetefromTn_> sweet
[17:20:06] <PetefromTn_> I managed to finish my PVC anodizing tank aerator
[17:20:31] <PetefromTn_> seems to work good or at least it makes lots of bubbles. If it were not for the acid I would quite enjoy a dip! ;)
[17:24:21] <PetefromTn_> http://imgur.com/zdwrxQh Working on some merge collectors for the big turbo car. What do you guys think so far?
[17:25:44] <Contract_Pilot> Walmart stepper/drivers still processing....
[17:29:56] <[cube]> looks great pete
[17:30:17] <PetefromTn_> you think so? I am trying to get this down man LOL
[17:30:38] <[cube]> welds are nice
[17:30:47] <[cube]> afraid i dont know much about custom headers tho
[17:31:02] <[cube]> zeeshan would know more
[17:31:08] <PetefromTn_> heh probably
[17:31:15] <PetefromTn_> I am still learning myself.
[17:35:19] <Contract_Pilot> http://www.stevenrhine.com/wp-content/uploads/2015/09/Walmart-Steppers-and-Drivers-1024x498.jpg
[17:36:02] <JT-Shop> looking good PetefromTn_
[17:36:36] <Contract_Pilot> the only diffreance is say items about to ship.
[17:37:30] <Contract_Pilot> But whonder what will be in the box for the price.
[17:38:08] <PetefromTn_> JT-Shop Thanks man. I am not where I want to be with it yet but I am getting better every day I work there I think..
[17:39:38] <andypugh> PetefromTn_: You are clearly a man who likes a challenge, how about this 4:1 in titanium? https://picasaweb.google.com/lh/photo/CMJx1MDjG_qDzzfPuPIFLCE34QWor4gUzfw_1O9qsPw?feat=directlink
[17:40:07] <PetefromTn_> nice andy did you make that?
[17:40:14] <andypugh> It’s not mine
[17:40:29] <PetefromTn_> looks THIN!
[17:40:41] <andypugh> A loony of my acquantance is trying to make it for his little V10 engine.
[17:41:00] <Sync> PetefromTn_: realistically you don't need more than 1.5mm
[17:41:05] <andypugh> it is also very small
[17:41:13] <PetefromTn_> LOL just noticed you can see my PRECISION CHINESE POS CNC vise in my picture
[17:41:28] <PetefromTn_> Sync on what?
[17:41:37] <Sync> headers
[17:42:51] <PetefromTn_> actually these things are very heavy duty because this thing will completely support a VERY large and heavy turbo charger
[17:42:55] <andypugh> Actually, that’s a 5:1 collector. And the tubes are probably 3/8” diameter :-)
[17:43:20] <PetefromTn_> and the heat generated here is substantial so typical thin tube will usually crack and fail quickly
[17:43:29] <Sync> you should mount the turbocharger not through the header
[17:43:39] <Sync> so that the tube is not stressed
[17:43:40] <andypugh> He is making them by a method which I suggested, 3D-printing a core and nickel-plating onto that.
[17:43:47] <PetefromTn_> that IS the mount
[17:44:08] <PetefromTn_> the turbo bolts directly to the mount that feeds it
[17:44:33] <PetefromTn_> some people add exterior supports but honestly there is not a lot of places on the turbo to connect to anyway
[17:44:39] <andypugh> Every turbo that I have worked on has hung directly from the header. It’s the only way to cope with thermal expansion.
[17:45:15] <PetefromTn_> believe me when I tell you that the manifold is more than up to the task of supporting the turbo
[17:45:25] <PetefromTn_> It could probably hold up my van LOL
[17:45:48] <Sync> yes, thus they are too heavy
[17:46:08] <Sync> andypugh: I've seen external mounts on 80s f1 cars
[17:46:15] <Sync> as they had issues with the headers cracking
[17:46:39] <Tom_itx> my kid gets to 3d print all the parts he's done in catia at school
[17:46:40] <PetefromTn_> yeah they are a little heavy but they serve a purpose and the car is hopefully going to make near 1k HP so I think it is a trade off LOL ;)
[17:47:02] <Tom_itx> i told him that might be nice to have to show what you've done
[17:47:52] <Sync> if they are cracking from heat, you are using the wrong material
[17:47:57] <Sync> http://www.gurneyflap.com/Resources/DSC_7693.jpg
[17:48:06] * ganzuul discovered the machinist's dance today!
[17:48:41] <Tom_itx> get hot chips down your pants?
[17:49:04] <Sync> http://www.gurneyflap.com/Resources/RENAULT%20RE20-296.jpg
[17:49:37] <ganzuul> Tom_itx: Shirt only, thankfully.
[17:50:00] <[cube]> welder's waltz lol
[17:50:11] <Tom_itx> better than getting weld slag in your boot
[17:50:36] <[cube]> got some slag flew in my visor
[17:50:43] <Sync> although I must say welding very thin inconel is annoying
[17:50:46] <[cube]> settle right next to my eye
[17:50:49] <[cube]> got a nice lil scar
[17:51:59] <Sync> andypugh: how about lost wax casting?
[17:52:59] <andypugh> Sync: The teeny headers are cracking when he melts out the plastic print. But he seeems to have solved that now.
[17:53:24] <Sync> hmm
[17:53:26] <andypugh> Sync: He is lost-wax casting some parts, he built a nice super-small scale DLP printer for that.
[17:53:27] <PetefromTn_> Oh that's a BITCH I have had hot chips fly up and land on my forehead, bounce off my glasses and land on the top of my cheekbone and BURN the crap out of me before...NO FUN
[17:53:44] <ganzuul> I need to get muself a cool looking clear visor. Almost got another chip in my mouth.
[17:54:08] <Wolf_Mill> worst ever, weld slag in ear
[17:54:19] <ganzuul> ...ouch
[17:54:25] <Sync> machine from solid andypugh? :D
[17:54:41] <Sync> should be a nice 5 axis excercise
[17:55:37] <andypugh> Sync: It’s this project: http://www.f1-2000.co.uk/index.php?f=conrods
[17:55:53] <PetefromTn_> Wolf_Mill I have been welding under my Wife's Mustang years ago and had some slag fall down.....there. almost knocked it off the jackstands trying to get out from underneath it while enjoying the sizzle LOL
[17:56:49] <PetefromTn_> damn that con rod is gorgeous LOL
[17:57:15] <Sync> neat
[17:57:31] <andypugh> Look at the section on fuel injectors
[17:58:43] <PetefromTn_> heh that damn tiny con rod probably got more machinist love than most of the parts I have ever made
[18:02:12] <ganzuul> ...Is that part a miniature?
[18:02:31] <ganzuul> derp
[18:02:41] <ganzuul> says in the page title.
[18:02:53] <PetefromTn_> hell yeah it is TINY
[18:03:25] <Sync> nice
[18:03:36] <Sync> although the injector is producing droplets
[18:04:02] <ganzuul> Are pneumatic valves still a thing for F1 engines?
[18:05:03] <Sync> yes
[18:06:08] <ganzuul> Those get pretty hot, right? What are they made of?
[18:07:44] <ganzuul> I have ruled out cheese.
[18:09:13] <Sync> high temp alloys
[18:09:21] <Sync> probably inconel with ti stems
[18:09:25] <Sync> or even ceramic
[18:09:40] <ganzuul> hmm
[18:10:53] <andypugh> The same chap has working pneumatic valves
[18:11:18] <andypugh> (not on the out-of-date web site yet)
[18:12:43] <andypugh> This is how he makes tiny valve collets https://www.youtube.com/watch?v=nOPW4-WRRMs
[18:21:56] <ganzuul> what is this an engine for ants
[18:22:21] <andypugh> A bit bigger than ants, but the challenge does seem to be the size.
[18:23:42] <Tom_itx> i wonder if he's keeping track of his man hours building it
[18:26:14] <andypugh> I doubt it
[18:26:28] <andypugh> He basically doesn’t seem to do much else.
[18:26:40] <andypugh> (well, he runs a company too)
[18:26:50] <Tom_itx> i was gonna ask if he was retired
[18:27:08] <andypugh> He spends a lot of money, latest toy is a 4-reservoir dental grit-blasting setup.
[18:27:53] <andypugh> http://www.renfert.com/gbr/en/products/dentist-mini-laboratory/fine-sandblasting-units/basic-quattro.html does not look cheap
[18:29:50] <SpeedEvil> http://www.ebay.co.uk/itm/191423803099?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT - how would you make these?
[18:30:00] <SpeedEvil> They are ~0.8mm or so thick stainless
[18:30:09] <SpeedEvil> Would these simply be spun from flat?
[18:30:24] <Tom_itx> probably
[18:30:27] <Tom_itx> or stamped
[18:30:27] <SpeedEvil> Or welded from the base and a pipe?
[18:30:51] <andypugh> SpeedEvil: https://www.youtube.com/watch?v=WsbeREDUkn0
[18:30:52] <SpeedEvil> I am wondering as one has developed a pinhole 1/4" up the side
[18:31:07] <Tom_itx> if it's annealed when drawn they may run it thru a press
[18:31:25] <Tom_itx> dunno
[18:31:55] <ganzuul> There are thin-bottomed and thick-bottomed cookware.
[18:32:13] <SpeedEvil> yeah - this is much, much, much shittier than that
[18:32:20] <SpeedEvil> the bottom is thin stainless
[18:32:33] <SpeedEvil> the same guage as the walls
[18:33:13] <Tom_itx> https://www.youtube.com/watch?v=8uuFWzkRcAg
[18:33:16] <Tom_itx> SpeedEvil,
[18:33:33] <Tom_itx> those are aluminum though
[18:33:39] <ganzuul> How It's Made has made me believe these would be made through a series of die presses.
[18:33:59] <ganzuul> Same was as aluminium cans.
[18:34:54] <ganzuul> Well poop. That's what Tom_itx posted.
[18:35:27] <andypugh> I posted one on stainless induction pans
[18:35:42] <SpeedEvil> andypugh: yes - but nice ones - with three layer bottoms
[18:35:52] <Tom_itx> andy knows all about spinning metal
[18:36:10] <SpeedEvil> I diddn't think it could spin that high.
[18:36:37] <SpeedEvil> But the walls seem as thick as the base.
[18:36:53] <SpeedEvil> surely if it was spun, the top would be double the thickness of the base or more?
[18:37:22] <Tom_itx> i've never bothered putting a mic on one
[18:37:58] <SpeedEvil> I now wish I had the appropriate tools to measure it.
[18:38:02] <andypugh> You can spin thicker or thninner
[18:38:21] <SpeedEvil> oh
[18:38:24] <Tom_itx> it's probably up to where and how you use the tools
[18:38:29] <SpeedEvil> yeah - the radius isn't constant
[18:38:48] <andypugh> ie, you can stretch over the former or lay onto the former. It is that control over thickness that keeps spinning still commercially viable.
[18:39:00] <SpeedEvil> yeah - I see that.
[18:39:09] <SpeedEvil> I'd naively assumed it was a simple folding process
[18:39:25] <SpeedEvil> but it can stretch the metal too 'away' from the blank
[18:50:22] <jthornton> I like the golang channel, #go-nuts lol
[19:00:10] <PetefromTn_> Damn I need a lathe heh
[19:05:06] <jdh> buy a lathe
[19:05:32] <PetefromTn_> I need to machine a V band flange heat sink so I can tig weld these things properly without distorting the piss out of them LOL
[19:11:03] <robinsz> evening ...
[19:11:20] <robinsz> andypugh, I wonder if you can assist me?
[19:11:38] <andypugh> Yes, but only briefly at 0047
[19:11:40] <andypugh> :-)
[19:12:31] <robinsz> I have this car that keeps failing its emissions test ...
[19:12:41] <robinsz> I figure a small software tweak ...
[19:12:45] <robinsz> ;)
[19:12:58] <andypugh> (I seem to have spent most of the evening trying to find my ssh keys to be able to push to the git repository)
[19:13:10] <robinsz> have you looked behind the sofa/
[19:13:17] <andypugh> robinsz: VW by any chance?
[19:13:25] <robinsz> hah
[19:13:46] <Wolf_Mill> wouldnt be a vw
[19:13:56] <robinsz> I bet there are a few worried manufacturers out there to be honest
[19:13:58] <Wolf_Mill> they come factory equipped :P
[19:14:48] <t12> lathe leveling, round two
[19:15:00] <Wolf_Mill> http://i.imgur.com/2TlF5xE.jpg does the fact that my mom bought this the same day off set the VW emmisions?
[19:15:00] <robinsz> Wolf_Mill, all manufactueres have done some tweaking for the tests, VW just did a little more than most
[19:15:17] <andypugh> VW blatently cheated. That’s not quite the same
[19:15:26] <robinsz> shrug
[19:15:28] <Tom_itx> andypugh, is that pin new since the demo in 2.7.0 release?
[19:15:51] <Wolf_Mill> yeah, but is it cheating if the game is already rigged?
[19:15:58] <andypugh> Tom_itx: Yes. Well, it was about at the same time but the demo went in to 2.7 and the new pin only into master
[19:16:08] <Tom_itx> ok
[19:16:24] <robinsz> andypugh, well I suspect when they look into real world performance versus test, the playing field will be pretty level
[19:17:15] <Wolf_Mill> ford deisels just had a emmisions software update as well, my friends dads truck went from 20mpg to 11-15mpg and keeps killing sensors now
[19:17:27] <andypugh> One of the clinching bits of evidence was that someone took a VW and a BMW from the showroom and did a test drive with some portable emissions equipment. The VW was 30x over stated emissions. The BMW was _under_
[19:17:38] <andypugh> (The BMW is the more surprising result to me)
[19:18:29] <robinsz> interesting ...
[19:18:41] <robinsz> I assume this was nox levels?
[19:18:50] <andypugh> Wolf_Mill: That’s not likely to be related, there hasn’t been time for Ford to get a software release out yet.
[19:19:03] <andypugh> robinsz: I don’t know, but assume so
[19:19:16] <Wolf_Mill> not related to VW
[19:19:39] <andypugh> And saying “Ford diesels” is a bit of a broad statement.
[19:19:47] <robinsz> andypugh, I always assumed the americans concentrated on nox, because of they set tight limits on co2 all their homegrown would struggle
[19:20:16] <andypugh> Some Ford Diesels are getting a software update in the next couple of weeks because I screwed something up..
[19:20:26] <robinsz> oopsie :)
[19:20:46] <Wolf_Mill> 2012 and newer
[19:20:59] <andypugh> robinsz: I think that they are super-strict on NOx because some of them live in a desert.
[19:21:07] <Wolf_Mill> 6.7 w/ dpf and def systems
[19:21:17] <robinsz> andypugh, speaking of which, I bought an (older) diesel xmax recentyl ... very impressed on mileage
[19:21:23] <robinsz> smax
[19:21:26] <andypugh> And any suggestion that emitting CO2 is bad is a Communist Plot
[19:21:41] <robinsz> there is that
[19:21:51] <andypugh> 2 litre S-max?
[19:22:03] <robinsz> got 57mpg on run back from france, fully loaded with kit and kids
[19:22:15] <andypugh> That is pretty good.
[19:22:31] <Wolf_Mill> http://i.imgur.com/PDmtpSd.jpg
[19:22:40] <andypugh> None of my doing, I just made it quiet :-)
[19:22:48] <robinsz> mmm, I forget, 2007 vintage ..
[19:23:30] <andypugh> Wolf_Mill: Is that the Adblue consumption with the new calibration?
[19:23:34] <robinsz> whatever, its an awesome vehicle, we loves it
[19:23:45] <Wolf_Mill> haha
[19:24:09] <robinsz> I only got it because adamanda had one and rated it
[19:24:14] <andypugh> Yeah, I was fairly proud of the S-Max
[19:24:18] <MacGalempsy> hello :)
[19:24:19] <CaptHindsight> Wolf_Mill: what vehicle is that pic from?
[19:24:30] <CaptHindsight> 51.6mpg
[19:24:35] <Wolf_Mill> thats the other problem w/the 6.7 ford update, truck started eating adblue like crazy
[19:24:48] <Wolf_Mill> my golf wagen
[19:25:11] <Wolf_Mill> I average 37-42mpg per tank
[19:26:01] <robinsz> want to see what I cut on my EMC controlled router?
[19:26:32] <Praesmeodymium> the nitrous emmsions were responsible for californias photchemical smog, r at least a larg contributor. we have areas where the weather can put a cap on a valley and leave the stale air there for weeks
[19:26:49] <Praesmeodymium> I think the smog concern is why we are so strict on those
[19:27:06] <zeeshan|2> hi friends
[19:27:38] <andypugh> Praesmeodymium: Indeed, but it might make more sense to ban cars there, than to set NOx emissions low everywhere because of there. (As there is a fairly straight trade-off between low NOx and fuel efficiency)
[19:28:26] <MacGalempsy> Central Cali has several cities in the top 10 of worst air quality
[19:28:54] <Wolf_Mill> ^ seen a few people on the VW forums grumbling about delete kits and malone tunes if there is a recall ecm flash
[19:28:56] <MacGalempsy> Hot valley air raises up, sucks in all the nasty bay area air

[19:29:32] <Praesmeodymium> yeah well its this whole 2 govenrments problem really makes for interesting things
[19:29:40] <MacGalempsy> nice work robinsz
[19:29:45] <Praesmeodymium> states rights vs federal laws
[19:29:56] <robinsz> full 8x4 sheet

[19:30:57] <robinsz> it takes 4.5 hours to run a full sheet
[19:31:03] <andypugh> robinsz: Vacuum table?
[19:31:16] <robinsz> andypugh, yes, 10hp
[19:31:24] <zeeshan|2> how come youre routing that?
[19:31:27] <zeeshan|2> and not laser/waterjet
[19:31:46] <robinsz> zeeshan|2, laser would be too poor edge quality
[19:31:52] <andypugh> And more to the point, just how many letter boxes do you have?
[19:32:04] <robinsz> 2U front panels for amplifiers
[19:32:23] <Contract_Pilot> Feel icky!
[19:32:30] <MacGalempsy> pic of final product?
[19:32:36] <robinsz> andypugh, I glue the 6mm ally to 2mm MDF with spray contact adhesive
[19:32:55] <robinsz> keeps that centre from moving about
[19:33:11] <Contract_Pilot> Funny reading the review on another site same seller on walmart market place order a cable sent an unbrella!

[19:34:37] <Contract_Pilot> is the catagory maybe they send a box of air freshners
[19:34:38] <robinsz> MacGalempsy, I dont have any pics to hand, but if you look here you'll get the idea: http://pa.matrixamplification.com/mf-series/xt7000mf.html
[19:34:47] <andypugh> Not that there is anything wrong with having a pile of wood soaked in solvent. It might even be useful.
[19:34:57] <robinsz> andypugh, binfire night is coming
[19:35:58] <andypugh> Be a bit careful, though. Isn’t white spirit one of the solvents that can spontaneously ignite rags / wood?
[19:36:15] <robinsz> I thought that was linseed?
[19:37:01] <MacGalempsy> cool. do you make a tube amp?
[19:37:01] <robinsz> anyway, we spread it around outside and let it evaporate, then take straight to dump, it doesnt come back in
[19:37:06] <robinsz> yes.
[19:37:29] <robinsz> http://usa.matrixamplification.com/guitar-amps.html
[19:37:53] <renesis> ha matrix amps
[19:37:54] <robinsz> just running another batch of 200 this week
[19:37:57] <renesis> that guy is pretty cool
[19:38:01] <andypugh> robinsz: Sounds like you are OK anyway “The classic example of spontaneous ignition is rags soaked in linseed oil. The spontaneous ignition of oil-soaked rags is not as common as it used to be because of the popularity of acrylic paints that do not require the use of ‘drying oils’ such as linseed oil. However, the problem still occurs with oil-based paints and some timber stains and polishes. Linseed oil is the m
[19:38:01] <andypugh> common example of a ‘drying oil’ but rapeseed, cottonseed, peanut, corn oil and safflower oil may also self-heat. Fish oils are notorious for their self-heating properties. Mineral oils like white spirit, mineral turpentine or lubricating oil are not prone to self-heating and will not cause spontaneous ignition."
[19:38:06] <renesis> wonder if he still sells with out certification tags
[19:38:23] <DaViruz> i've found white spirits to be quite tricky to set on fire even if you're trying hard
[19:38:41] <robinsz> renesis, all USA stuff is sold with a part 15 declaration
[19:39:00] <andypugh> DaViruz: That makes it one of the better fuels for fire-breathing
[19:39:04] <renesis> when i worked at line 6, they had the matrix amps guy in about doing contract work for them, they asked him how he came up with his great guitar amps
[19:39:18] <DaViruz> it really only burns with a wick it seems
[19:39:18] <robinsz> renesis, ah that was Andy
[19:39:21] <renesis> engineering already knew they were standard mosfet AB amps with offline switcher power supplies
[19:39:32] <CaptHindsight> hmm self cooking fish, must investigate this oil phenomenon
[19:39:38] <DaViruz> andypugh: makes sense!
[19:39:47] <robinsz> renesis, yeah, line6 are really good at amps
[19:39:52] <renesis> so he tells the big wigs OH YEAH THATS JUST A STANDARD APPLICATION CIRCUIT FROM THE MOSFET COMPANY
[19:40:03] <renesis> engineering thought it was awesome, the musicians felt lied to
[19:40:08] <robinsz> renesis, how is that PA gear selling btw?
[19:40:10] <MacGalempsy> my dad has been buying old tube radios the last few months. he buys boxes of them then tests and resales on ebay
[19:40:25] <renesis> robinsz: i was the lead tech on the speakers, heh
[19:40:26] <MacGalempsy> boxes of tubes that is
[19:40:36] <DaViruz> i've never been much of a fire breather myself.
[19:40:36] <renesis> as far as i know, theyre not selling, which most of us expected
[19:40:44] <robinsz> renesis, thats correct.
[19:41:01] <robinsz> are you at the LA amp show?
[19:41:05] <renesis> which is correct?
[19:41:10] <renesis> no ive never been
[19:41:10] <DaViruz> though i'll admit i have something of a pyromanic streak..
[19:41:11] <robinsz> they are not selling
[19:41:15] <renesis> and i dont live in LA right now
[19:41:18] <robinsz> k
[19:41:29] <robinsz> we are still waiting for Helix samples
[19:41:30] <renesis> also line 6 was like 4 years ago
[19:41:34] <robinsz> right
[19:41:38] <renesis> man that thing looks hella sexy
[19:41:42] <renesis> but wtf at the price
[19:41:55] <robinsz> its a bit in the cheap end of market
[19:42:08] <robinsz> half the price of AxeFX
[19:42:09] <renesis> really? thing is like $1600, no?
[19:42:13] <robinsz> yeah
[19:42:22] <renesis> axefx is like $3k?
[19:42:23] <renesis> damn
[19:42:25] <robinsz> yeah
[19:42:31] <renesis> who the fuck is buying this shit
[19:42:35] <robinsz> I have AxeFX and Kemper here
[19:42:40] <robinsz> everyone!
[19:42:47] <renesis> kemper stuff looks pretty neat
[19:43:10] <robinsz> yeah, it is
[19:43:25] <robinsz> we sell a shit tonne of amps to AxeFX guys
[19:43:40] <robinsz> and a smaller number to kemper
[19:44:44] <renesis> anyway, CTO of line 6 retired so its basically fucked
[19:44:56] <robinsz> well, it is now part of Yamaha
[19:45:03] <renesis> everyone thinks marcus is the brains but that guy couldnt design himself out of a cardboard box
[19:45:18] <robinsz> it was all going south when Bruce joined
[19:45:34] <renesis> bruce who?
[19:45:52] <norias> Burce Campbell
[19:46:02] <renesis> and yeah yamaha is been pretty hands off but theyre not hitting sales goals so who knows how much longer
[19:46:12] <CaptHindsight> not the actor
[19:46:25] <renesis> yeah dunno about him over there
[19:46:47] <robinsz> sorry, brain fart ... Joe
[19:47:04] <renesis> the 'acoustic engineer' they had do the PA stuff was just an old project manager friend of marcus'
[19:47:21] <robinsz> Yamaha is only really interested in the radio mic stuff
[19:47:45] <renesis> guy didnt know much, but he knew enough to bring doug button in at some point
[19:47:46] <robinsz> they'll give it a shot with helix, but if it doesnt fly, I think there will be trouble
[19:48:00] <renesis> well i think they wanted the variax stuff for their guitars
[19:48:10] <robinsz> yes, thats true
[19:48:10] <renesis> prob sucked to find out shit wasnt modularized at all
[19:48:18] <robinsz> heh
[19:48:34] <renesis> that was my first project at line 6, the next gen variax
[19:48:35] <robinsz> well, we'll see where it goes
[19:48:52] <renesis> cool tech, DFM sucks
[19:48:59] <robinsz> we are releasign some new speaker/amp products to go with Helix
[19:49:13] <renesis> where are you working?
[19:49:19] <robinsz> im in UK
[19:49:30] <robinsz> but we have factoy in Ventura
[19:49:48] <robinsz> I flew the production samples out for the show this week
[19:50:36] <Wolf_Mill> yay I made something with the cnc (first thing I would call a real part anyways) http://i.imgur.com/fD7Z76M.jpg its almost square... and holes are mostly round lol
[19:50:39] <robinsz> a neat powered 12" and a powered 10"
[19:51:37] <renesis> would love to have time to make some audio trash
[19:51:39] <robinsz> Wolf_Mill, the bearing holder part?
[19:51:45] <Wolf_Mill> yup
[19:51:49] <robinsz> renesis, :) where are you located?
[19:52:11] <robinsz> Wolf_Mill, neat
[19:52:17] <renesis> north cali for school, 90 miles north of sacramento
[19:52:26] <robinsz> oh, well north
[19:52:26] <renesis> im down in LA for work during breaks
[19:52:47] <robinsz> well, feel free to hit me up, I am occasionally in vnetura
[19:53:08] <robinsz> you know the guys at Mission Engineering? i think they are up your way
[19:53:21] <renesis> nope but that sounds familiar
[19:53:34] <renesis> i think someone else asked the same thing actually, haha
[19:53:45] <andypugh> OK, time to go.
[19:54:14] <robinsz> Petaluma
[19:54:22] <robinsz> night Mr Pugh
[19:55:14] <renesis> my availability is kind of fucked for a couple more years
[19:56:02] <renesis> tho lack of opportunity while at school was one of the reasons i moved here, heh
[19:56:11] <malcom2073> Wolf_Mill: Awesome!
[19:56:11] <robinsz> hah
[19:56:33] <renesis> for example, petaluma is like 3 hours from here, so getting there during the semester wont happen
[19:56:39] <robinsz> right
[19:56:48] <robinsz> america is so ... big
[19:57:01] <renesis> and while im sure i could find work in the bay area, i dont have a place to stay, and i have to keep my place at school
[19:57:09] <renesis> in LA i have places to crash
[19:57:26] <robinsz> you go to NAMM?
[19:57:26] <Wolf_Mill> oops, and I just blew up the AC servo board
[19:57:35] <robinsz> oopsie
[19:57:48] <renesis> fuck i cant while in school its always the week after spring session starts
[19:57:53] <robinsz> shame
[19:57:57] <renesis> im seriously sad about it
[19:57:59] <renesis> yeah
[19:58:06] <robinsz> i fly over every year for it
[19:58:17] <renesis> its such a great show
[19:58:19] <robinsz> except this last one, was busy moving factory
[19:58:51] <renesis> ive only been to 3, but its fuckin overwhelming i really wish i could make it
[19:59:06] <robinsz> I usually do 3 days, and still dont see it all
[19:59:18] <robinsz> I do frankfurt as well
[19:59:19] <renesis> your ventura place is a CM or you guys own it?
[19:59:26] <robinsz> CM?
[19:59:32] <renesis> contract manufacturer
[19:59:33] <malcom2073> Wolf_Mill: Lol whups, what happened?
[19:59:40] <robinsz> no we own
[19:59:46] <renesis> very nice
[19:59:51] <robinsz> own SMT lines
[20:00:05] <renesis> very very nice
[20:00:11] <robinsz> just opening up a woodshop for the cabinets
[20:00:14] <Wolf_Mill> pot hit the heatsink, blew some shit up
[20:01:06] <malcom2073> Damn
[20:01:13] <renesis> ive thought about opening up a little audio CM
[20:01:33] <robinsz> dunno if there is money in it
[20:01:36] <renesis> something like 100 miles out from LA or the bay
[20:01:51] <robinsz> would people not just sub contract to China?
[20:01:51] <renesis> well its the assumption that the china shit stops working in 3-4 years
[20:02:08] <renesis> and companies are setup to work with CMs instead of running their own factories
[20:02:13] <robinsz> but, if its your design just PCB stuffed and cased in china
[20:02:26] <renesis> because theres problems
[20:02:38] <robinsz> it works for us in USA, because we get full retail
[20:02:38] <renesis> like, thats all ive worked with for the past 7 years
[20:02:53] <robinsz> but subcon, its low margin
[20:03:05] <renesis> right, most companies are 3PL and CM based engineering companies
[20:03:16] <renesis> and china is getting less profitable every year
[20:03:20] <robinsz> it is
[20:03:21] <malcom2073> Wolf_Mill: https://scontent-iad3-1.xx.fbcdn.net/hphotos-xpa1/t31.0-8/12028650_1143085655705814_5572230064951336056_o.jpg
[20:03:26] <renesis> also its pissing engineers off, burning them out
[20:03:31] <robinsz> yup
[20:03:33] <renesis> and its fucking up schedules over and over
[20:03:50] <robinsz> well, we do that to ourselves :)
[20:04:04] <renesis> its going to come back to america for the same reason it went to china, the accountants will figure out theyre not making money anymore
[20:04:11] <robinsz> yep
[20:04:17] <Wolf_Mill> malcom2073: cool
[20:04:23] <renesis> at the very least i think its going to shift to central and south america
[20:04:44] <robinsz> renesis, what is funny to watch is GC imploding
[20:04:56] <robinsz> thats one to avoid
[20:05:00] <renesis> the time zone thing is huge, a huge part of the issues is people are communicating technical shit while half asleep in broken language
[20:05:07] <robinsz> heh
[20:05:17] <renesis> GC deserves whatever happens to them
[20:05:27] <robinsz> yep, its coming ...
[20:05:39] <renesis> theyre such assholes, ive heard they talk about sam ash like theyre a threat they gotta kill
[20:05:45] <renesis> talk about kickin a dead guy
[20:06:07] <robinsz> its just too big and stuffed full of debt
[20:06:58] <robinsz> well, that rapidly went from CNC to "Audio Industry Insider" didint it?
[20:07:11] <renesis> wonder how many people just use them as a showroof for online amazon and sweetwater purchases now
[20:07:50] <robinsz> they still shift a lot of stuff, but not much of the high margin stuff anymore
[20:07:51] <renesis> shrug, audio people hiding everywhere
[20:08:03] <robinsz> sweetwater are very focused
[20:08:11] <robinsz> and very marketing led
[20:08:27] <robinsz> their cubefarm is vast
[20:08:34] <renesis> im amazed how coordinated their sales guys are
[20:08:38] <robinsz> yep
[20:08:49] <renesis> like they will find me the dude i ordered shit from 2 years ago at another company
[20:08:50] <robinsz> some big CRM stuff going on there
[20:08:57] <robinsz> yep
[20:09:54] <robinsz> we stay away from the retailers tbh
[20:10:02] <robinsz> prefer lower volume at full margin
[20:10:09] <renesis> great way to cut your profits in half instantly
[20:10:22] <robinsz> yep
[20:10:26] <robinsz> and get paid late
[20:10:32] <renesis> put yourself in a lot of corners regarding inventory
[20:10:53] <robinsz> we do fine through our webshop
[20:11:04] <renesis> carvin style
[20:11:05] <robinsz> and one or two boutique outlets
[20:11:15] <robinsz> liek Tonemerchants
[20:11:50] <renesis> you can keep track of that tho
[20:11:58] <robinsz> exactly
[20:12:20] <renesis> GC would troll stanton/cerwin-vega/krk so hard
[20:12:31] <robinsz> i can imagine
[20:12:46] <robinsz> when theyhave the whiphand ...
[20:12:52] <renesis> COOL WE REALLY LIKE THAT NEW PRODUCT, WERE GONNA GIVE YOU ALL THE OLD ONES BACK SO YOU CAN MAKE A BUNDLE WERE GONNA SELL AT THIS
[20:13:05] <robinsz> yeah
[20:13:12] <renesis> like, no money made, but they do it anyway because where else you gonna sell that many
[20:13:22] <renesis> lose money on it sitting on a 3PL shelf
[20:13:32] <robinsz> yup, we dont play that game
[20:13:41] <robinsz> full price or no dice :0
[20:13:59] <robinsz> ok, I admit, I did give Metallica a discount ;)
[20:14:25] <renesis> like, im as sick of corporate audio as i thought i would be, but you learn a ton gettin the shit made at a price that actually supports the business
[20:14:56] <renesis> robinsz: yeah see most companies would have just given metallica the gear
[20:15:00] <robinsz> yeah, we do everyting we can in house, otherwise you die on margin
[20:15:18] <robinsz> renesis, yeah, but then they dont value it
[20:15:31] <renesis> course not
[20:15:58] <robinsz> they use ours all the time now, in all their touring rigs
[20:16:00] <renesis> line 6 gave gary busey an amp, spider valve i think
[20:16:03] <robinsz> all paid for
[20:16:19] <renesis> the tech who loaded into his truck said it was all very puckey smelling
[20:16:27] <robinsz> hah
[20:16:28] <renesis> they just gave everything away
[20:16:36] <robinsz> we never do that
[20:17:03] <robinsz> I love musicians asking for 50% off ...
[20:17:26] <renesis> see its funny because you guys can probably afford that
[20:17:43] <robinsz> "sure, well, I didnt give Metallica 50% .. but, if you are bigger/more famous, then sure, you can get 50%"
[20:17:49] <renesis> the companies ive worked for arguably couldnt, and 50% was the standard artist discount
[20:18:09] <robinsz> 30% is for "good" artists,
[20:18:20] <renesis> so basically, jimi hendrix gets 50%
[20:18:22] <robinsz> 20% for "Ive heard of you"
[20:18:42] <robinsz> no one gets 50% ;)
[20:19:01] <renesis> cmon if zombie hendrix showed up you guys would 50% him
[20:19:15] <robinsz> we dont make a left handed amp though ...
[20:19:25] <renesis> ive never really consider him plus digital effects
[20:19:30] <robinsz> nope
[20:19:33] <renesis> dude hell just run it upside down itll be fine
[20:19:49] <robinsz> but axefx is very very good for real amp sounds
[20:20:01] <robinsz> Lifeson is using it now
[20:20:43] <PetefromTn_> THE Lifeson?
[20:20:49] <renesis> yeah, not a rush head
[20:20:56] <robinsz> and most AxeFX users buy our amps
[20:21:00] <PetefromTn_> Oh I am LOL....
[20:21:08] <renesis> rush to me is pretty good music with bleating sheep vocals
[20:21:19] <renesis> baaah baaaaaah
[20:21:26] <PetefromTn_> I'm sorry that you have no taste ;)
[20:21:44] <robinsz> right ... bedtime for me
[20:21:50] <renesis> if i had budget for an active speaker prototype rig, which i dont, id prob use matrix amps
[20:21:59] <renesis> kk nite
[20:22:10] <robinsz> well, hit me up for b stock ;)
[20:22:13] <robinsz> nite
[20:22:23] <renesis> prob take you up on that
[20:22:25] <renesis> nite
[20:22:27] <robinsz> do
[20:25:46] <renesis> heh, guitarists at a place i worked were like MATRIX AMPS SO BRIGHT SO SPRINGY GREAT RESPONSE SO MAGIC
[20:26:46] <renesis> we measured them, totally normal amps, was great. the shit guitarists are used to is pretty sad, heh
[20:31:46] <furrywolf> I've found speakers make far, far, far more of a difference than amps, unless you're talking the cheapest crap or anything with STK chips.
[20:32:00] <MacGalempsy> renesis: i mentioned my dad had been picking up tube radios and record players. He will not stop with how good the 1940s radios sound. somewhere the art of sound has been lost
[20:39:18] <renesis> they didnt even know how to tune low frequency response back then =(
[20:40:43] <renesis> macgalempsy: i have an older friend who is an electronic engineer, audio specialized since the 70s, very knowledgable but also very subjective about his likes and dislikes
[20:41:17] <renesis> anyway, he says his first pair of headphones when he was a kid in iran, has never heard as good a pair of headphones since
[20:42:36] <CaptHindsight> his ears also probably haven't worked as well since then
[20:42:41] <furrywolf> the best headphones I've heard were a pair of older full-ear-covering Koss ones. probably not the best out there, but better than average.
[20:43:02] <renesis> yeah that may actually be true
[20:43:16] <renesis> because truly good modern headphones didnt happen until he was in his 30s
[20:43:36] <furrywolf> (oldering being '80s, not super old)
[20:43:37] <renesis> furrywolf: headphones are pretty personal
[20:43:39] <furrywolf> older
[20:43:40] <CaptHindsight> I have worked with a lot of well know audio people over the years
[20:44:08] <renesis> peoples opinions dont correlates with measurements as clearly as with loudspeakers
[20:44:24] <CaptHindsight> we would often have conversations about distortion you can measure and "distortion" only some people can hear :)
[20:44:33] <renesis> also their is the issue of measurement, since you have to load up the front side of the headphone cup correctly
[20:44:52] <renesis> and everyones ear loads the headsphones differently, so they dont even sound the same one person to the next
[20:45:18] <CaptHindsight> but as far as the good ol days from the 60's and earlier when you refurb that old equipment you find that it's what people remember hearing it sounded like vs what it really sounds like
[20:45:25] <renesis> capthindsight: honestly some people can hear inaudible shit, blind tested
[20:46:10] <renesis> most people, they start hearing it somewhere around 1%
[20:46:27] <malcom2073> Not only that, but you lose range as you get older
[20:46:32] <malcom2073> So things you remember *will* sound different
[20:46:43] <Contract_Pilot> thinking i may convert the sherline to ball screw PRM0601 ball acrew
[20:46:50] <CaptHindsight> WHAT, speak up son :)
[20:46:57] <malcom2073> Haha, not that kind of range :P
[20:46:58] <Contract_Pilot> http://www.thomsonlinear.com/en/product/PRM0601
[20:47:26] <furrywolf> I have a coworker whose range is down to about 6ft, if you yell. :P
[20:48:04] <renesis> want to get my hearing tested a few times
[20:48:21] <CaptHindsight> why would your coworker throw his plane down in a well?
[20:48:31] <renesis> dont care so much about bandwidth or sensitivity, as long as theyre matched okay
[20:48:42] <furrywolf> LOL
[20:48:45] <furrywolf> LOL!!!!!
[20:48:47] <furrywolf> he does tha too.
[20:48:50] <furrywolf> that
[20:49:50] <CaptHindsight> I wish my ears would go deaf to baby crying
[20:50:14] <Jymmm> CaptHindsight: Easy, snip-snip
[20:50:27] <CaptHindsight> vocal cords?
[20:50:35] <Jymmm> testicals =)
[20:50:41] <CaptHindsight> sounds kinda drastic
[20:50:45] <zeeshan|2> Contract_Pilot: itll be worth more than the ball screw
[20:50:55] <Jymmm> No more baby maker, just the playpen =)
[20:51:00] <zeeshan|2> er the mill
[20:51:01] <zeeshan|2> i mean
[20:51:17] <Contract_Pilot> no telling
[20:51:28] <CaptHindsight> horse has left that barn decades ago
[20:51:36] <Jymmm> lol
[20:51:45] <CaptHindsight> my kids are all grown
[20:51:51] <Jymmm> CaptHindsight: Then were is the baby crying coming from?
[20:52:30] <malcom2073> Jymmm: 6ft down the well apparently
[20:52:38] <Jymmm> lmao
[20:52:56] <Jymmm> Timmy fell down the well you say Lassy?
[20:53:43] <jdh> how much is a prm0601 screw/nut?
[20:53:57] <CaptHindsight> Jymmm: seems everywhere I go there are crying babies
[20:54:09] <Jymmm> CaptHindsight: ah
[20:54:15] <CaptHindsight> just lucky I guess
[20:54:25] <furrywolf> I think restaurants need to have separate "family seating" ... out back.
[20:54:38] <CaptHindsight> way out back
[20:54:50] <malcom2073> I think people that don't want to hear people shouldn't be in public
[20:54:51] <malcom2073> :P
[20:54:52] <CaptHindsight> even sitting at the bar doesn't seem to help
[20:55:21] * Jymmm ducttapes malcom2073
[20:55:56] <malcom2073> That being said, there is crying babies, and then there's screaming kids
[20:56:12] <Jymmm> malcom2073: which one are you?
[20:56:18] <malcom2073> Jymmm: I'm a bit of both :P
[20:56:27] <Jymmm> malcom2073++
[20:56:33] <CaptHindsight> lol, bbl
[20:56:45] <Jymmm> Is there a place to get ceramic fiberboard cheap?
[20:57:11] <Jymmm> refactory board or whatever it's called
[20:57:55] <malcom2073> Jymmm: Find a local clay/pottery place and ask? They may carry that sort of stuff
[20:58:12] <Jymmm> malcom2073: thanks
[20:58:42] <malcom2073> One of the ones around here carried refactory cement when I was calling around, so I'd imagine that's not a far stretch
[21:02:07] <Praesmeodymium> Jymmm: local to me is a place called gerogies
[21:02:20] <Praesmeodymium> http://www.georgies.com/
[21:02:49] <Praesmeodymium> all kinds of refactory stuff, the brick and board is much much easier to work that then wool products
[21:03:28] <Jymmm> Praesmeodymium: I dont even see brick there
[21:05:24] <Praesmeodymium> http://www.georgies.com/gcc-shop-kiln-parts.shtml
[21:07:34] <Wolf_Mill> http://i.imgur.com/DVwnSsB.jpg oops
[21:08:03] <Praesmeodymium> thatlooks electrical
[21:08:12] <malcom2073> Damn Wolf_Mill
[21:08:23] <malcom2073> Repairable?
[21:08:31] <Jymmm> Wolf_Mill: Were you licking the 440V again?
[21:08:46] <Wolf_Mill> thats a copper trace that was on the board, 1/8" away from the heatsink
[21:09:04] <malcom2073> Easy fix :P
[21:09:12] <Jymmm> ceramic fiber board - good pricing http://www.ceramaterials.com/ceramicfiberboards.html
[21:09:39] <Wolf_Mill> 2x 10 ohm resistors, totally gone, blew them clean out of the solder
[21:09:44] <malcom2073> Nice
[21:10:18] <Wolf_Mill> I have a 5.6ohm 2w, should might work lol
[21:11:13] <Wolf_Mill> one more trace to jumper and need it id a component then see if it still works
[21:14:30] <Wolf_Mill> http://i.imgur.com/d86e03l.jpg before shit went sideways...
[21:19:44] <Wolf_Mill> http://i.imgur.com/CyNObxX.jpg board... two next to the rect bridge are the ones that vaporised
[21:21:02] <malcom2073> Shouldn't be bad to fix
[21:24:00] <Contract_Pilot> to much work. https://www.youtube.com/watch?v=EC6LrVxeqZk
[21:24:09] <Contract_Pilot> Requires a new saddle
[21:24:30] <Wolf_Mill> now, right before I let the smoke out of it, I was thinking that if its a MCU running the show, its probabaly a analog input, might be able to shoot pwm direct to it and control the speed
[21:25:12] <Wolf_Mill> it also doesnt care where the input is when switched on, if its at full throttle on powerup it ramps to full
[21:32:20] <Tom_itx> Wolf_Mill, not goin so good?
[21:33:53] <Wolf_Mill> was going good then I made oops
[21:37:45] * Jymmm hangs his tophot up for another year
[21:37:50] <Jymmm> top hat*
[22:02:41] <Wolf_> weee
[22:05:58] <Contract_Pilot> Unless my cheet sheet is Wrong wolf R100 is .1ohm not 5 phm
[22:06:15] <Praesmeodymium> sounds right to me
[22:06:27] <Praesmeodymium> I just looked up r200 resistors they are .2
[22:07:17] <Wolf_> err crap
[22:09:49] <Contract_Pilot> From the size they look like 1-2 watt that circuit it P(W) Resistor = I(A) Rectifiet × V(V) Capacitor
[22:10:15] <Contract_Pilot> Reason for 2 is to increase watts of the circuit. '
[22:10:32] <Wolf_> yep, around a 6432 metric pack
[22:11:32] <Contract_Pilot> Whats the Voltage of C32?
[22:12:12] <Contract_Pilot> Cannot tell if it is connected to the restitors in the photo
[22:15:04] <Contract_Pilot> You can use a standard thru hole resistor keep leads short
[22:17:16] <Wolf_> http://imgur.com/a/KfGUN Cap: http://i.imgur.com/RJNgBcT.jpg
[22:18:07] <Wolf_> I’m doubting that I have any 0.05Ω laying around here
[22:18:41] <Contract_Pilot> 78L15 should be a =15 Voltage Regulator
[22:18:57] <Contract_Pilot> .1 ohm
[22:20:23] <Wolf_> 0.1Ω… can I just cut some 14awg house wire? lol
[22:22:24] <Contract_Pilot> Without seening details of the circuit idd just stick with .1 ohm got with more wats than 1-2
[22:23:13] <Praesmeodymium> how many volts and amps?
[22:24:44] <Contract_Pilot> that circuit should have 8 watts 4 Min
[22:24:52] <Wolf_> pair resistors look to start at the 250V cap and go to the under side trace, via to the other two resistors and the white motor lead
[22:25:21] <Praesmeodymium> I realized I was looking at the wrong calulator 40 feet of 14g fo .1 ohm
[22:25:54] <Praesmeodymium> sounds like an inductor pretty quickly
[22:27:00] <Contract_Pilot> What componant blew to cause the damage on the heat sink?
[22:27:03] <Wolf_> twist some 28awg kanthal wire together? lol
[22:27:12] <Wolf_> just a trace
[22:27:50] <Wolf_> the pot hit the heatsink, I think caused a arc from the bottom trace
[22:27:51] <Praesmeodymium> kanthal wire lol vaping on the electronics it dual purpose
[22:28:56] <Contract_Pilot> Photo of the bottom of the board.
[22:30:04] <Contract_Pilot> Ready to fix wolf_'s Controller hahaha http://www.stevenrhine.com/wp-content/uploads/2015/07/Ham-Shack-And-PCB-Rework-Lab-Small.jpg
[22:31:47] <Contract_Pilot> Here you go wolf! http://www.hobby-hour.com/electronics/smdcalc.php
[22:32:07] <Wolf_> http://i.imgur.com/PiF65X7.jpg
[22:32:25] <Wolf_> lol
[22:33:04] <Wolf_> I have a weller WM1000 w/ wmrp pencil and a hot air rework station
[22:34:13] <Wolf_> and where that trace went after the via http://i.imgur.com/qwYweFV.jpg
[22:38:55] <Contract_Pilot> Check that 78L15 and the Diode
[22:39:34] <Wolf_> well, I know the 78L15 started to smoke
[22:40:20] <Contract_Pilot> Yea, if you vaped a trace.
[22:40:47] <Contract_Pilot> Now what did you hook up wrong?
[22:41:18] <Wolf_> only thing wrong is the resistor
[22:41:58] <Contract_Pilot> Ok, I would not stuff that 5hom in there.
[22:41:58] <Wolf_> vaped traces were easy to follow, pretty deep grove left over lol
[22:42:16] <Contract_Pilot> Lots of current to Vape a trace.
[22:42:54] <Wolf_> wonder if the e-cig wire would work for temp resistor lol
[22:43:12] <Wolf_> they handle 27W @ 3.7v lol
[22:43:15] <Contract_Pilot> You would just be making a wire wound resistor.
[22:44:09] <Contract_Pilot> I would not go over .1ohm ot you may vape the jumper wire hahaha
[22:45:23] <Contract_Pilot> Them resistors look like they limit the curent that cap then filters the voltage
[22:45:39] <Wolf_> e-cig typical build use to be 0.5ohm 7wrap coils :)
[22:46:12] <Contract_Pilot> make a .1 ohm and try why not you alreay vaped the trace.
[22:46:39] <Wolf_> that was a low current trace that got vaped
[22:46:48] <Contract_Pilot> Yea,
[22:47:17] <Wolf_> guess the pot short caused the caps to dump
[22:47:24] <Contract_Pilot> Be sure to use ciramic to insulate it or will become a heating coil
[22:48:02] <Contract_Pilot> Do you have a DMM?
[22:48:18] <Contract_Pilot> a nice one with current cut off? '
[22:48:35] <Wolf_> I have DMM, Scope, and a DE-5000
[22:48:41] <Wolf_> LCR meter
[22:49:51] <Wolf_> current cutoff?
[22:49:54] <Contract_Pilot> My scope is in the attic
[22:50:41] <Contract_Pilot> Check how many amps if going from pad to pad.
[22:50:58] <Wolf_> oo hmm
[22:51:22] <Contract_Pilot> Also check the voltage of both sides.
[22:51:49] <Contract_Pilot> you may be able to just jumper it
[22:52:37] <Contract_Pilot> Data sheet for the 78L05 if it is on the + side it may be just a protection circuit.
[22:52:47] <Contract_Pilot> 70L15
[22:54:10] <Contract_Pilot> but if they are using the resistors to make it an adjustable output you need .1ohm
[22:54:28] <Wolf_> trying to think what I can scrounge from around here
[22:55:14] <Contract_Pilot> http://www.futurlec.com/Linear/78L15.shtml
[22:55:59] <Contract_Pilot> What pin of the reg is the vaped trace?
[22:56:10] <Contract_Pilot> Cannot tell from the photo.
[22:56:52] <Contract_Pilot> Wow my walmart order has shipped!
[22:56:56] <Contract_Pilot> Amazing.
[23:00:51] <Wolf_> can’t tell, center or closest to teh HV side (big caps) right side in the pic?
[23:01:22] <Contract_Pilot> Well PSU's did.. http://www.stevenrhine.com/wp-content/uploads/2015/09/PSU-Shipped-1024x512.jpg
[23:03:03] <Contract_Pilot> I will be sure to videotape the unboxing
[23:03:12] <Wolf_> lol
[23:03:34] <Wolf_> I did that w/ the Facebook measurement gear I bought
[23:03:39] <Contract_Pilot> The review of the company Orderd a Cable sent an Unbrella hahaha
[23:04:24] <Contract_Pilot> Yea, the to good to be true deals document it.
[23:04:58] <Contract_Pilot> If they ship the motors and drivers will be supprized.
[23:05:01] <Wolf_> mostly cause the guy listed caliper/mic/DTI for $300, then his GF posted the stuff split up, then 2 people said they wanted the mic and calipers, then the post got deleted
[23:05:32] <Contract_Pilot> Ahhh
[23:05:57] <Contract_Pilot> One day ill pull my Metcal BGA stuff out of the attic.
[23:06:01] <Wolf_> 2 mitsu and a interapid for $300…
[23:06:25] <Contract_Pilot> I do not buy used indicators.
[23:07:08] <Wolf_> http://i.imgur.com/Sbd6BWE.jpg
[23:07:36] <PetefromTn_> did you buy that from the facebook page?
[23:08:02] <Wolf_> the Mitsu and interapid yeah
[23:08:15] <PetefromTn_> I thought I saw those on there hehe
[23:09:00] <Contract_Pilot> http://www.walmart.com/ip/46914656
[23:09:03] <Wolf_> they were on there for like 4-5 days with no comments or anything
[23:09:32] <Contract_Pilot> https://www.facebook.com/ContractPilot
[23:09:47] <Contract_Pilot> Wolf my FB
[23:14:40] <Wolf_> wonder what odd shit in the shop might have R100 stuck on it...
[23:19:44] <Praesmeodymium> I thinkif we are just spitballing, thats close to a graphite from a .7mm mechanical pencil
[23:20:17] <Wolf_> lol, I can always check it on the LCR
[23:24:50] <Contract_Pilot> Yep.
[23:25:28] <Contract_Pilot> I think they are using it as either a Current Limit Circuit or Variable Regulator
[23:26:45] <Wolf_> ok, going to go poke around the pile of dead electronics in the shop lol
[23:30:05] <MacGalempsy> What do you guys think? http://fayar.craigslist.org/tls/5239631675.html
[23:30:39] <Contract_Pilot> Craigs list offer 1/2
[23:30:54] <MacGalempsy> it was at $650 a few weeks ago
[23:31:09] <MacGalempsy> it seems like a killer deal
[23:32:54] <PetefromTn_> if you have use for all that hardware it is a steal...
[23:33:39] <PetefromTn_> I agree with pilot tho LOWBALL em LOL
[23:33:59] <MacGalempsy> the boxes are like 300 each new
[23:34:21] <MacGalempsy> if they accept the first offer, you just paid too much
[23:39:39] <Contract_Pilot> Low ball works they have a bunch left.. http://www.stevenrhine.com/wp-content/uploads/2015/09/PSU-Ebay.jpg
[23:40:21] <Contract_Pilot> http://www.ebay.com/itm/271968689926
[23:40:39] <Contract_Pilot> 48V 10A should be Enough for the G0704
[23:41:02] <Contract_Pilot> Small machines can use the walmart switcher
