[00:00:49] <XXCoder> oh yeah its MOVIE that is 1960s. book is quite a lot older.
[00:04:24] <XXCoder> I hope I still have that book. mine must be very early edition with more plain machine
[00:11:17] <XXCoder> dang
http://colemanzone.com/Time_Machine_Project/TimeMachinePrint%282%29.htm
[00:11:21] <XXCoder> so many editions.
[00:11:22] <Jymmm> I gave up all books (dead trees) except for refernce stuff.
[00:13:02] <XXCoder> I dont buy much dead tree versions much now
[00:14:30] <Jymmm> XXCoder: Audio Books huh? <snickers>
[00:14:40] <XXCoder> very useful, that. :P
[00:15:07] <Jymmm> XXCoder: Yeah, you dont' get interupted by words and such and can just concentrate on the content =)
[00:15:28] <XXCoder> lol
[00:15:55] <XXCoder> man I really need to find my edition as it does NOT appear in that huge list of editions.
[00:16:23] <Jymmm> Dont forget to use lots of duct tape on it too!
[00:16:52] <Jymmm> Then it'll be the redneck edition
[00:17:26] <XXCoder> :P
[00:17:44] <Jymmm> I have a physics book that's 114yo now, binding in great shape too
[00:17:48] <XXCoder> time traveler says "hey hold my beer and check this" gets in time trailer and travels
[00:18:00] <Jymmm> lmao
[00:18:21] <Jymmm> ...to the liquor and ammo drive in store!
[00:18:31] <Jymmm> in? thru? both?
[00:18:52] <XXCoder> 8 sequels heh all by different authors
[00:19:09] <XXCoder> nah, back to when ammo was cheap and liquor even cheaper
[00:20:10] <XXCoder> http://www.timemachinemodels.com/
[00:20:36] <Jymmm> cute

[00:45:52] <XXCoder> https://covers.openlibrary.org/b/id/6569990-L.jpg finally found it
[00:46:17] <XXCoder> nice nonecludian cover
[00:59:24] <XXCoder> hey Jymmm download link workf or you?
http://naomivorster.com/book/2164027/12-2015/the-time-machine-great-illustrated-classics.html
[01:00:38] <Jymmm> XXCoder: No, just some redirect to plaster.com
[01:01:01] <XXCoder> no wonder it didnt work, noscript blocked that
[01:01:22] <XXCoder> stupid site.
[01:02:05] <Jymmm> XXCoder:
http://www.planetpdf.com/planetpdf/pdfs/free_ebooks/The_Time_Machine_NT.pdf
[01:02:39] <XXCoder> yeah that I already found
[01:02:56] <XXCoder> all illusiations is not there, it has to be specific edition that does have
[02:18:53] <Deejay> moin
[02:20:22] <XXCoder> yo
[03:07:10] <chupacabra> what do people use to make gcode to feed linuxcnc?
[03:07:34] <archivist> inside rear of skull
[03:07:40] <chupacabra> lol
[03:07:54] <chupacabra> I used to could do that.
[03:08:11] <archivist> I am not kidding, its the right way for my type of job
[03:08:31] <XXCoder> magic
[03:08:48] <archivist> mostly making regular shapes with a gcode loop
[03:08:53] <chupacabra> im remembering the age of post processors and stuff.
[03:09:09] <archivist> that age has not passed
[03:09:47] <chupacabra> oh noes. I kinda figured not. Still lots of big iron out there.
[03:10:22] <archivist> they all do something different hence the need for post processors
[03:10:41] <chupacabra> My 3040t is finally running correctly so now time to put it to work.
[03:11:35] <chupacabra> i can make designs in librecad but need g code now.
[03:11:37] <archivist> you dont get comments in cam output
http://www.archivist.info/cnc/wormtest/wormtest.ngc
[03:12:30] <archivist> that is a test for worm reduction quality
[03:13:24] * chupacabra has been wondering what .ngc files are.
[03:15:54] <XXCoder> there is no effective free gcode processors from what I see. however there is plenty of paid programs that can
[03:19:41] <anomynous> chupacabra, if you do 2.5d or equilevant in 4th axis its fine to learn gcode. Its easy, really. Rapid, feed, interpolation plane, coordinate systems, polar/cartesian coordinates, radius/length compensations, drilling cycles. Coordinate system rotation too. Not much, and you could do after reading with 2 A4 cheat sheets.
[03:19:51] <anomynous> its a big plus to actually know what your machine is going to do on the next line
[03:19:52] <anomynous> :D
[03:20:09] <anomynous> XXCoder, fusion doesnt have a post for linuxcnc?
[03:20:30] <XXCoder> actually didnt know fusion had any post?
[03:20:37] <anomynous> it does have plenty with it
[03:21:32] <anomynous> hmm
[03:21:33] <chupacabra> I been machining since before CNC. Wheeee.
[03:21:46] <anomynous> or are we talking of something else than post processor? o.0
[03:21:52] <anomynous> chupacabra, =)
[03:22:34] <XXCoder> anomynous: can fusion import models?
[03:22:39] <anomynous> yes
[03:22:55] <anomynous> you have to upload them on the interwebs and have them appear in the app
[03:23:11] <XXCoder> cool as I dont really like modeling on fusion, though I gonna try more
[03:23:31] <anomynous> the modelling for imported models is non-modal by default
[03:23:41] <anomynous> err
[03:23:43] <anomynous> parametric
[03:23:44] <anomynous> :D
[03:25:42] <XXCoder> ok

[04:19:16] <archivist> there is a youtube video , it is a pointy clicky instant cam on the machine
[04:19:26] <archivist> sort of
[04:20:06] <archivist> a bit like some modern cnc machines have for one off and simple programming
[04:49:43] <XXCoder> anyone played zelda, the ocarina of time?

[07:01:03] <pink_vampire> morning
[08:15:24] <Kevin`> trentster: ping?
[08:27:12] <trentster> howdy Kevin`
[08:30:20] <Kevin`> trentster: can has comment?
http://etmalec.net/~kevin/biospages/
[08:37:47] <Deejay> remote bios?
[08:37:54] <Deejay> via AMT or such thing?
[08:37:58] <pink_vampire> Kevin`: how did you get the bios from the terminal??
[08:38:11] <Deejay> hi pink_vampire
[08:38:12] <Kevin`> pink_vampire: ipmi, it's a server board
[08:38:19] <Deejay> ah nice
[08:38:43] <pink_vampire> ok..
[08:38:52] <pink_vampire> not that impresive.
[08:39:44] <pink_vampire> I thought you use some driver or something
[08:40:03] <Kevin`> it's one of those fanless things targetting who knows what
[08:40:20] <Kevin`> you can do it with a bios driver, but that would probably add overhead that would be counterproductive
[08:40:32] <Kevin`> this is a seperate chip. not that it seems to be helping in this situation
[08:41:06] <pink_vampire> what kind a machine is that?
[08:41:31] <pink_vampire> I'm looking for now for small pc, or din rail mounted pc.
[08:42:02] <Kevin`> pink_vampire: it's old, you probably don't want it. but i think this is the model:
http://www.supermicro.com/products/motherboard/ATOM/ICH9/X7SPA.cfm?typ=H&IPMI=Y
[08:43:57] <pink_vampire> nice..
[08:45:24] <pink_vampire> I wish i can get smaller board with dual serial
[08:53:48] <__rob> hello
[08:54:41] <__rob> can anyone tell me how BSPP connectors are meant to work
[08:54:50] <__rob> for air hose
[08:55:17] <__rob> it looks like it a parallel thread, but then for female and male it would be metal on metal
[08:55:27] <__rob> I dont see how it would seal
[08:57:00] <__rob> unless its an actual thread
[08:57:07] <__rob> but it looks like its just rings of thread parallel
[08:59:07] <archivist> should be taper for a proper seal
[08:59:59] <archivist> parallel uses some other sealing method (ptfe tape or o ring)
[09:00:22] <archivist> you can use ptfe tape ot taper threads
[09:03:18] <archivist> a fibre washer is also used on a parallel thread nut to face
[09:06:26] <archivist> original method before ptfe tape was so wind some string around the thread and wipe it with a linseed putty type of compound
[09:18:41] <gonzo_> the BSPP ones I've used, rely on a 60deg cone to seal. The threads are just for tension
[09:19:09] <gonzo_> usually for hydraulic piping
[09:19:38] <gonzo_> or screw a taper into a pll as said, with ptfe tape
[09:20:27] <gonzo_> a washer would be ok with an airline, but not for high pressure
[09:37:39] <Demure_> Hey! Considering running my current lathe project on LinuxCNC but have a small question
[09:37:52] <Demure_> I have a decent encoder here, but it's rated at 10.000 pulses per rotation (so 40.000 steps)
[09:38:25] <Demure_> Would LinuxCNC and say mesa 7I76 / 5I25 combo be able to handle this at max 2000rpm?
[09:38:37] <archivist> you would need a hardware interface (mesa) to read that encoder at speed
[09:39:13] <archivist> a bit too good for a spindle :)
[09:39:54] <pink_vampire> http://www.newegg.com/Product/Product.aspx?Item=N82E16813157656
[09:40:08] <cradek> 7i76 does have one encoder input channel
[09:40:23] <pink_vampire> where is the power for the 2.5 sata disk?
[09:40:34] <Demure_> Thanks. :) I want to use the spindle as a C-axis, too. I believe the mesa board has an encoder input, but I'm unsure what differences there are between the different inputs / channels.
[09:41:05] <cradek> is your encoder differential?
[09:41:21] <Demure_> Incremental
[09:41:40] <cradek> I mean the wiring. does it have like A, /A, B, /B?
[09:41:49] <archivist> does it have A- and A+
[09:42:06] <_methods> don't you need 7i77 for servos
[09:42:11] <Demure_> It has A, A-, B, B-, N and N-
[09:42:22] <cradek> then the 7i76 can count it at 10 MHz
[09:42:43] <cradek> see page 50 of the 7i76 manual
[09:43:17] <Demure_> Thanks! Apologies if I could've found it, it's all a bit tricky right now
[09:44:14] <cradek> no problem, I knew where to look
[09:44:41] <Demure_> Another question, if that's okay. I have bought what seems like a high quality VFD / inverter and a Siemens 0.55khz motor. I've read in some places that in certain specifics a VFD can be used as a C-axis when paired with an encoder
[09:44:48] <Demure_> What would the requirements be for this?
[09:45:16] <archivist> depends on the vfd not all can do that
[09:45:43] <Demure_> What specifications and details would I have to look through in the manual?
[09:45:53] <Demure_> i.e. what terms to look out for?
[09:46:04] <archivist> servo is one
[09:46:11] <cradek> if my math is right, 10MHz count rate would happen at 250 rps which is 15000 rpm
[09:46:46] <Demure_> That should be more than enough
[09:46:52] <cradek> yeah a vfd is usually not used for positioning
[09:47:40] <Demure_> I figured, but I was pondering between going with a servo to run the spindle at high speed until this option came along and figured I could always attach a servo if I needed to do any C-axis work, until I read somewhere about someone using a VFD for such a purpose
[09:53:33] <cradek> I suspect it's common for VFDs to have a basic positioning mode, like for tool orient, but you are talking about a mode that positions and counteracts machining forces etc, and that's a different story
[09:53:51] <cradek> I think the type of motor needed for those different applications is very different too
[09:55:16] <Demure_> That kind of use would make more sense and in line what what I knew about VFDs, thanks
[09:55:30] <Demure_> Guess I'll have to figure out a good way to attach a servo or stepper to the spindle. :)
[09:58:17] <cradek> yeah, maybe mechanical switching between the two motor/driver types would be ideal, if you can build that
[09:58:40] <cradek> I have no experience with positioning spindles (except for orient)
[09:58:41] <archivist> or nudge it to location and apply brake
[09:58:50] <cradek> there might be good solutions but I don't know them
[09:59:05] <cradek> yes depends if you need just indexing or full contouring
[09:59:31] <pink_vampire> hi
[09:59:33] <Demure_> Indexing would work for the majority of the cases
[09:59:48] <Demure_> I'll see how precise I can get the motor to control and otherwise I'll install a servo
[10:00:04] <archivist> what are you intending to make
[10:00:17] <Demure_> Drill some holes mostly
[10:00:37] <Demure_> But ideally I'd also do some engraving
[10:00:46] <Demure_> Making lens mounts :)
[10:01:04] <archivist> servo then
[10:01:41] <Demure_> Ok, thanks for taking the time to answer!
[10:03:55] <archivist> I am thinking of bayonet mount there
[10:49:58] <archivist> what sales blurb

[10:56:20] <pink_vampire> archivist: what is that?!
[10:57:25] <ssi> lol
[10:57:27] <archivist> a tool used in conjunction with an angle dekkor for measuring how much a rotary table rotates
[10:57:35] * ssi bids 5 pounds
[10:57:44] <t12> what do you think the reserve is
[10:58:09] <archivist> some silly amount, I have one so I am not going for it

[11:00:30] <ssi> what's a laser printer polygon
[11:01:11] <SpeedEvil> polyganol mirrors which are used to scan the LASER across the drum.
[11:01:12] <t12> i believe they do

[11:01:35] <t12> and old busted laster printers are... free
[11:02:12] <SpeedEvil> t12: no, they're not
[11:03:03] <t12> areound here they are

[11:12:51] <Jymmm> What is it (polygon)?
[11:13:53] <archivist> a set of mirrors on an axis

[11:15:32] * archivist repeats a tool used in conjunction with an angle dekkor for measuring how much a rotary table rotates
[11:15:51] <Jymmm> ah
[11:16:32] <archivist> https://en.wikipedia.org/wiki/Precision_polygon
[11:20:28] <SpeedEvil> Terrible article.
[11:20:33] <SpeedEvil> But gives the idea
[11:21:33] <archivist> there is some sense on

[11:23:16] <archivist> at least that page has the method of checking micrometer anvils see dowell prism lower down
[13:58:18] <enleth> makita bandsaw just arrived. quite pleased with build quality, except the fence, it's shit
[13:59:17] <enleth> otherwise a very nice tool
[13:59:30] <CaptHindsight> painted and bent 20ga sheet metal?
[14:00:02] <enleth> fence? wobbly aluminum extrusion
[14:00:16] <enleth> and the rear clamp is a joke
[14:01:39] <CaptHindsight> http://www.makita.co.za/css/hrimages/LB1200F.jpg similar to this?
[14:02:15] <CaptHindsight> lower res pic
http://ecx.images-amazon.com/images/I/41FkAP-V3NL._SY300_.jpg
[14:02:18] <enleth> exactly this
[14:02:34] <enleth> unless there are regional differences
[14:02:56] <enleth> but looks same
[14:03:15] <enleth> the table is a really nice hefty chunk of cast iron
[14:03:43] <enleth> there's a piece of ground rod aligning the split at the front
[14:04:31] <_methods> how much was that bandsaw?
[14:04:40] <CaptHindsight> I always talk myself out of those types/grades of tools when I see them on sale somewhere
[14:04:49] <skunkworks> I bought myself a craftman impact driver kit. (impact driver, drill, 2 batteries and charger) I needed some batteries as my original set (drill, circle saw, sawzall) was down to one sort of working battery. I love the impact driver. been drooling over getting one for a while.
[14:04:54] <CaptHindsight> unless it comes with lunch
[14:05:29] <skunkworks> and that set was cheaper than getting 2 replacment batteries at the time
[14:06:02] <enleth> _methods: an equivalent of $450 or so, but somebody else paid for it, so I'm fine with the price
[14:06:14] <_methods> hehe
[14:06:17] <_methods> the best price
[14:06:39] <CaptHindsight> skunkworks: I did the same with buying batteries. The whole new drill with 2 batteries was 1/2 the price of the batteries alone
[14:06:54] <_methods> yeah i just ditched my old drills this weekend
[14:07:03] <_methods> got some of the new 18v ones
[14:07:15] <_methods> lipo batteries or whatever
[14:07:20] <skunkworks> CaptHindsight, yep - plus I get the li-ion batteries and charger.
[14:07:38] <_methods> li-ion yeah not lipo
[14:07:53] <_methods> makita lxt
[14:07:57] <enleth> anyway I was fed up with cheap chinese bandsaws so I decided to try an expensive chinese bandsaw
[14:08:03] <enleth> so far so good
[14:08:05] <skunkworks> I don't have to work at driving long screws in now.
[14:08:06] <CaptHindsight> it's funny in China when you buy cordless tools you just ask by battery voltage
[14:08:27] <CaptHindsight> mostly no name but the price and quality goes up with the voltage
[14:09:02] <_methods> i've always had pretty good luck with makita
[14:09:10] <enleth> it must be better, the numbers are higher
[14:09:28] <Jymmm> CaptHindsight: I love that Craftsman (aka rebranded Ryobi cordless tools use a propritary connecter so you can't use other batteries
[14:09:42] <skunkworks> I have only used craftsman.. No real reason other than the original (which I still have and use) was on super sale.
[14:10:10] <_methods> i've had good luck with hitachi too
[14:10:23] <_methods> my makita batteries way outlasted my hitachi batteries though
[14:12:16] <skunkworks> huh - price is back up. Was 109

[14:12:45] <CaptHindsight> after New Years back to reality price increase :p
[14:13:49] <CaptHindsight> _methods: his are 19.2V, not puny 18V :)
[14:14:05] <_methods> hahah tru
[14:14:22] <_methods> i'm comfortable with the size of my batteries at this point in life though
[14:15:50] <CaptHindsight> heh they actually are up to 60V cordless tools now
[14:17:14] * Jymmm will wait for 220V 3 phase batteries
[14:17:18] <Tom_itx> must be small capacity batteries
[14:17:20] <CaptHindsight> lol
[14:17:33] <CaptHindsight> the AC battery
[14:17:43] <Jymmm> No, DC =)

[14:20:07] <CaptHindsight> a cordless lawn mower might as well use a deep cycle boat motor battery
[14:20:47] <Jymmm> Do you really need more than 32V ???
https://www.youtube.com/watch?v=gC3rB9f7DaU
[14:20:57] <Jymmm> err 36V
[14:21:19] * Tom_itx just wants 1 more volt than Jymmm
[14:21:54] <_methods> lol
[14:22:08] <Jymmm> Tom_itx: No problem, I'll always have 10x more AH's than you at any voltage ;)
[14:22:35] <_methods> he has to have more with all that resistance in his "brain"
[14:22:52] <Jymmm> _methods: it's all futile
[14:23:08] <_methods> hahaha
[14:23:15] <_methods> assimilation time
[14:23:29] <CaptHindsight> more like a leaky capacitor
[14:23:37] <_methods> lol
[14:23:48] <Tom_itx> gawd aren't we all glad it's Monday after a long break??
[14:24:04] <CaptHindsight> I need a break from my break

http://www.stellartech.com/STILandingPages/temperature-transmitters-g.html
[14:26:22] <CaptHindsight> Jymmm: do you have RS485 versions?
[14:26:45] <Jymmm> CaptHindsight: Not mine, just an ad I saw on amazon
[14:27:20] <Jymmm> CaptHindsight: It cays 232 485 and canbus
[14:27:32] <Jymmm> says*
[14:29:22] <CaptHindsight> whats the lowest cost version with ethernet?
[14:30:39] <CaptHindsight> thermocouple + *duino with ethernet serape?
[14:30:54] <Jymmm> CaptHindsight: temp range?
[14:31:03] <CaptHindsight> thermocouple + STM discovery board?
[14:32:07] <_methods> you could probably hook one of those esp8266's up to a thermocouple
[14:32:08] <CaptHindsight> Jymmm: type K 32 to 900 deg. F (0 to 482 deg. C)
[14:33:12] <_methods> they're like $2
[14:33:14] <_methods> if that
[14:34:23] <CaptHindsight> _methods: but I want thermocouple to device to ethernet to switch to modem to cable to modem to switch to PC
[14:34:38] <CaptHindsight> no newfangled wireless
[14:37:24] <CaptHindsight> forgot, cable co to NSA to cable co in the middle :)
[14:37:36] <_methods> oh
[14:37:40] <_methods> i thought you wanted wireless
[14:38:25] <_methods> wellllll in that case i'd buy a nexx wt3020 or gl.inet and attach it to a thermo and micro
[14:38:29] <CaptHindsight> unfortunately the businesses nearby are in a wifi power pissing contest
[14:38:38] <_methods> the nexx is like $15 and you can put openwrt on it
[14:38:43] <_methods> and it has 4 open gpio pins
[14:39:04] <_methods> and it's tiny
[14:39:13] <CaptHindsight> last time I scanned it was difficult to find a channel
[14:39:55] <bpuk> I missed the original question - but if you're looking for an ethernet capable thermocouple interface I've had luck in the past with a Pi and a MAX31855 add-on board
[14:39:59] <_methods> you want the wt3020h though if you go that route
[14:40:11] <_methods> it has 8mb flash
[14:40:44] <_methods> http://www.ebay.com/itm/Portable-Mini-NEXX-WT3020H-300Mbps-USB-Share-Wireless-Wifi-Router-Repeater-White-/121710445780?hash=item1c568204d4:g:Ej4AAOSwBLlVSa~h
[14:41:02] <CaptHindsight> https://wiki.openwrt.org/toh/nexx/wt3020
[14:41:16] <_methods> yeah that wiki
[14:41:27] <_methods> you don't want the 3020a
[14:41:32] <_methods> the 4mb flash is a killer
[14:41:52] <CaptHindsight> H F or AD then?
[14:42:13] <_methods> yeah
[14:42:25] <_methods> as long as it has at least 8mb flash life is good
[14:42:28] <_methods> you can do it with 4
[14:42:32] <_methods> but you lose the usb slot
[14:42:47] <_methods> you'd have to use a usb drive for extra space
[14:43:01] <_methods> if you don't care about losing usb then it doesn't matter which one you use
[14:43:51] <_methods> http://www.amazon.com/Gl-iNet-Router-Openwrt-Mobile-Control/dp/B00JKFE0FW
[14:43:55] <_methods> taht one is another good one
[14:43:58] <_methods> with 16mb flash
[14:44:55] <_methods> and 5 gpio
[14:45:31] <_methods> https://forum.openwrt.org/viewtopic.php?id=47715
[14:46:11] <_methods> taht one is nice because they broke out the gpio pins for you
[14:46:16] <_methods> just solder on some headers
[14:49:51] <CaptHindsight> still need some A/D
[14:50:18] <_methods> arduino pro micro for $4?
[14:50:24] <_methods> or pro mini
[14:50:31] <_methods> i think the pro micro is like $6
[14:51:41] <_methods> so $16/wt3020, $4/pro mini, $8/31855 board
[14:51:44] <_methods> $28
[14:51:57] <_methods> plus your thermocouples
[14:52:23] <_methods> you could probably skip the arduino and just read off the 31855 board
[14:52:36] <CaptHindsight> yeah was just looking at that
[14:53:19] <bpuk> using a 31855 is much much easier than worrying about doing the adc yourself - thermocouples get suprisingly tricky to layout well
[14:53:35] <CaptHindsight> easy peasy
[14:54:05] <CaptHindsight> my background was in analog and microwave
[14:54:16] <CaptHindsight> you kids today have it easy
[14:54:27] <bpuk> fair enough :) my background is hitting things with a hammer - getting my head around the cold-junction stuff took me a while ;)
[14:54:34] <Jymmm> CaptHindsight: Which probe would you use (link)?
[14:56:14] <_methods> what's that new fancy 2 wire thermocouple chip
[14:56:26] <_methods> max6675?
[14:56:36] <Jymmm> CaptHindsight: This?
http://www.amazon.com/Type-Measuring-Thermocouple-Sensor-3-3Ft/dp/B00CQFTZ4E/
[14:57:01] <_methods> nah it's a newer chip
[14:57:16] <_methods> you can read up to 10 thermocouples using 2 wires instead of 5 on 31855 i think
[14:57:18] <CaptHindsight> Jymmm: or similar
[14:58:22] <Jymmm> CaptHindsight: Ok, in dumbass speak how are those read/calibrated?
[14:59:21] <CaptHindsight> _methods: maybe MAX31850/MAX31851 cold-junction-compensated 1-Wire thermocouple-to-digital converters
[14:59:30] <_methods> yeah that might be it
[15:00:28] <_methods> yeah up to 16 locations
[15:00:35] <bpuk> Jymmm: unless you're using a chip to do the fiddly bit for you read the voltage across the junction (in millivolts) and lookup from a chart. The fiddly bit is that a second junction forms where you plug the thermocouple in
[15:01:13] <_methods> the ad597 might work good too
[15:01:21] <Jymmm> arduino MAX6675 K-type Thermocouple Temperature Sensor
https://www.youtube.com/watch?v=NTlPflr8hYY
[15:04:15] <chris_99> has anyone used ADS1248 out of interest, with an RTD, i was looking at that recently
[15:04:17] <bpuk> Reading a paper at the minute - they're currently using units of millimicroseconds. I think they mean nanoseconds. Unless it's an american convention I'm unaware of
[15:04:51] <CaptHindsight> that's just to confuse the maker crowd
[15:06:30] <CaptHindsight> bpuk: sounds strange unless the topic generally used microseconds and they made a 3 order of magnitude leap
[15:07:00] <bpuk> they're using thyratrons as switches if that helps date the paper?
[15:07:24] <CaptHindsight> sure it's not a scifi novel? :)
[15:07:35] <bpuk> and a polaroid camera to capture the oscilloscope waveform
[15:08:05] <bpuk> pretty sure :) just seemed an odd unit
[15:08:07] <CaptHindsight> was before they invented or coined the term nano-
[15:08:12] <Jymmm> bpuk: polaroid?! That's stupid... etch-a-sketch ftw
[15:08:52] <bpuk> yup, etch-a-sketch over 50 nanoseconds - can't see any problem there at all
[15:08:57] <CaptHindsight> _methods:
http://docs.getchip.com/#chip-hardware $9 with wifi
[15:09:21] <cradek> old schematics use M for kilo-ohm and MMF for microfarad
[15:09:25] <Jymmm> bpuk: Hey, some have talent and turning knobs. Other, well...
[15:09:35] <cradek> it's a big jumble and you just need to use the context
[15:09:39] <_methods> yeah the $9 computer lol
[15:09:44] <_methods> did they actually ship any yet
[15:10:04] * Jymmm slaps _methods with $8.... $1 computer
[15:10:31] <_methods> hehe
[15:10:46] <bpuk> thanks cradek - I don't normally look at electronic manuals/theses this old - some of the conventions are a bit... confusing
[15:11:09] <cradek> yes, they are terrible
[15:11:40] <CaptHindsight> _methods:
http://thehackernews.com/2015/09/chip-mini-computer.html says started around Oct 1
[15:11:40] <bpuk> particularly since a few lines later a constant is gives as 50 x 10^-16 seconds
[15:11:52] <bpuk> gah, that should have been -6
[15:11:57] <CaptHindsight> http://makezine.com/2015/09/24/the-9-computer-is-shipping-today/
[15:11:58] <_methods> oh wow they actually shipped some
[15:12:25] <CaptHindsight> _methods: Allwinner project and SOC
[15:12:46] <_methods> yeah that would be the way to go then
[15:12:46] <bpuk> I've spent about half the time reading this paper thinking 'if they'd had mosfet's when he did this, it'd have been done in a month'
[15:12:53] <_methods> much better than a little router
[15:13:26] <CaptHindsight> rather than watch a bunch of maker types types fumble a low cost SOC board project they decided to partner up and just make it themselves
[15:14:12] <bpuk> that said - it does have a _lot_ of really nice information - hence the reading
[15:14:37] <_methods> can you still get them for $9?
[15:15:02] <gromits> cradek: I posted a question to the -developers list regarding an Axis issue I have. Wondering if i could pick your brain on it here?
[15:15:04] <CaptHindsight> https://nextthingco.zendesk.com/hc/en-us
[15:15:36] <CaptHindsight> _methods: what they say
http://getchip.com/
[15:15:46] <_methods> preorder
[15:15:48] <CaptHindsight> not sure when new order will ship
[15:15:52] <_methods> shipping jun 2016
[15:16:16] <CaptHindsight> is that for the board or just cables and case?
[15:16:29] <CaptHindsight> odd sentence
[15:16:36] <_methods> it says preorder
[15:16:44] <_methods> i don't think you can get the chip yet
[15:16:49] <CaptHindsight> maybe the first were sample silicon
[15:17:01] <CaptHindsight> then they go back and fix
[15:17:23] <_methods> no idea
[15:17:23] <XXCoder> you get a protective cover for cpu side
[15:17:36] <_methods> i didn't think any had shipped
[15:17:44] <XXCoder> _methods: I have one
[15:17:50] <_methods> oh well there ya go
[15:18:04] <CaptHindsight> or they sold whatever on poopstarter and then are waiting for orders to build up for a second run of boards
[15:18:27] <XXCoder> basic chip is just board, cable to connect video out
[15:18:34] <CaptHindsight> XXCoder: does it work? Is there a list of bugs?
[15:18:46] <XXCoder> it does, it works quite well
[15:19:02] <XXCoder> I used my mini tv lol
[15:19:42] <_methods> for $9 i guess i'll just order one to try out lol
[15:19:44] <CaptHindsight> XXCoder: does the chip have any text about version? thats decipherable?
[15:19:58] <XXCoder> its still first edition
[15:20:02] <XXCoder> everythng
[15:20:27] <_methods> buwhahahahah
[15:20:31] <_methods> $6 for shipping
[15:20:38] <_methods> that's where they get ya
[15:20:45] <_methods> so it's a $15 computer
[15:20:47] <_methods> not a $9
[15:21:02] <XXCoder> still quite cheap
[15:21:09] <_methods> now i'm not going to get one just because that's dirty
[15:21:22] <XXCoder> I need to get board addon for different video type
[15:21:30] <XXCoder> really? there is worse ones
[15:21:59] <CaptHindsight> how much is shipping for 10 boards? still 6 or 60?
[15:22:05] <_methods> no idea
[15:22:11] <_methods> i closed it after i saw that stupid shipping
[15:22:14] <XXCoder> try add 10
[15:22:34] <CaptHindsight> but it comes in a pretty box
[15:23:13] <_methods> i picked 3
[15:23:18] <_methods> and shipping is $7
[15:23:20] <XXCoder> what impresses the heck out of me is bnuilt in wifi
[15:23:33] <_methods> i guess that isn't too bad
[15:23:40] <XXCoder> I didnt know that, must have missed that in kickstarter details
[15:23:58] <XXCoder> raspberrypi you has to use usb one
[15:24:24] <XXCoder> my bro is getting the portable version
[15:24:54] <_methods> i guess i will get one now since they're not tryin to rape on the shipping
[15:25:25] <XXCoder> my guess is initial one needs handling, but it dont increase much handling to add 2 or 3 so on.
[15:25:29] <XXCoder> limited to 5 interesting
[15:26:28] <XXCoder> $11 to ship 5
[15:26:52] <XXCoder> $2.20 each chip
[15:26:57] <_methods> yeah i can live with that
[15:27:07] <XXCoder> someone have suggested them to change name because its as ungoogleable as hell
[15:27:07] <_methods> but $6 was kinda stupid
[15:27:18] <XXCoder> handling included I guess
[15:28:26] <_methods> aren't those pi zero's cheap too
[15:28:31] <XXCoder> $5
[15:28:37] <XXCoder> plus shipping I guess
[15:28:54] <XXCoder> if I recall, weaker stats than chip
[15:29:09] <XXCoder> oh guess im wrong on case
[15:29:13] <XXCoder> $2 for case
[15:29:23] <XXCoder> gees bit high there
[15:30:16] <_methods> man thats crazy for $5
[15:30:37] <_methods> onboard wifi with the chip though
[15:31:02] <XXCoder> I guess case and very short composite cable included was kickstarter only
[15:44:15] <_methods> ah good i don't even need a monitor for that thing
[15:44:31] <_methods> if you connect to the micro usb it starts a usb-serial connection
[15:45:22] <XXCoder> nice
[15:45:47] <XXCoder> so it means I can get display from chip that way too?
[15:45:54] <_methods> yeah i thought it was going to have to dig up some silly rca adapter to connect to a monitor or something
[15:46:16] <XXCoder> or buy $15 car backup tv heh
[15:46:21] <_methods> no need
[15:47:03] <_methods> just do a screen/cu/picocom connect to it
[15:47:18] <XXCoder> need to leasrn how. thanks
[15:47:56] <_methods> 115200/8n1
[16:09:28] <Tom_itx> are we searching for lcnc in a pocket pc's now?
[16:29:52] <JT-Shop> on eyephones
[16:36:41] <Jymmm> CaptHindsight: I found a k-probe solution =)
[16:43:30] <CaptHindsight> anyone should be able to run their 5 ton CNC mill or lathe using a controller that fits in your pocket or can get lost on your desk :)
[16:43:51] <CaptHindsight> and cost <$50
[16:44:09] <cradek> wirelessly
[16:44:23] <Jymmm> wireless powered!
[16:46:08] <Jymmm> wireless motors!!!
[16:56:25] <Demure_> Let's make it a keychain. :)
[16:57:35] <Deejay> gn8
[17:55:26] <witnit> I have always only built brush dc systems with encoders, now I have these brushless motors with resolvers. Can I pull the resolver, add an encoder and exclude hall sensors/resolver?
[17:56:21] <witnit> a b lines to the drive and a/ b/ line to the controller? Is this common practice?
[17:59:25] <CaptHindsight> yes, but people also keep their resolvers with linuxcnc
[17:59:35] <witnit> Oh?
[17:59:53] <witnit> What is the best way to commutate in my scenario (i usually use mesa cards)
[18:00:32] <CaptHindsight> maybe 7i48, let me check
[18:00:56] <CaptHindsight> 7i48
[18:01:05] <CaptHindsight> sorry 7i49
[18:01:19] <CaptHindsight> http://store.mesanet.com/index.php?route=product/product&product_id=101
[18:01:32] <CaptHindsight> ask PCW for details
[18:01:55] <witnit> 7i33 should be same right?
[18:02:06] <witnit> I only need two axis in this scenario
[18:02:40] <CaptHindsight> http://store.mesanet.com/index.php?route=product/product&path=83_86&product_id=92
[18:02:56] <CaptHindsight> servos with encoders
[18:03:04] <witnit> I been using the 7i90+7i33 with tons of success, but I wasnt sure how to get the resolvers into the loop
[18:03:21] <witnit> just ditch the resolvers and use ONLY encoders correct?
[18:04:00] <CaptHindsight> you can but your resolvers might have better res and you already have them
[18:04:22] <witnit> this particular amp BE25A20AC has an encoder input it seems
[18:04:35] <witnit> yeah but, where exactly would I wire this resolver
[18:05:01] <CaptHindsight> then again 7i49 is $184 vs whatever your encoders might cost
[18:05:10] <witnit> right
[18:05:20] <witnit> the 49 is resolver input
[18:05:41] <CaptHindsight> thats what the description says :)
[18:06:11] <CaptHindsight> several well respected members of the community here use them
[18:12:29] <witnit> oh ok I didnt notice up above you corrected the 48 to 49 :)
[18:31:27] <CaptHindsight> Best comment I've read in years: "I plan on starting a service called "nothing at all like a lawyer" where for a fee I will show up and defend you in court. Only I'll not know anything about the law, not be covered under any regulations, and bear no professional responsibility, so when your ass gets sent off to prison that's your damned problem. I'm also thinking of buying a dremmel tool and branching out into the "nothing at all like a
[18:31:27] <CaptHindsight> dentist" business. That's probably pretty lucrative too."
[18:32:12] <CaptHindsight> due to the magical thinking of Uber, a car for hire through an app isn't anything like a taxi and isn't subject to regulations because they say so. Nothing at all like a taxi.

[20:04:35] <chupacabra> high production going on here. one cnc mill and 2 3d printers. Welcome to my new world.
[20:05:55] <chupacabra> could have never imagined this back in 1972
[20:06:23] <malcom2073> Amazing what you can do in your garage nowadays
[20:06:31] <chupacabra> learning to use a shaper
[20:06:52] <chupacabra> im in my aptarment
[20:07:34] <chupacabra> lol
[20:08:07] <chupacabra> been grinning at the cnc mill since i got it all lined up today
[20:08:19] <malcom2073> Heh nice
[20:08:58] <chupacabra> my config is not like any on the www either. Wheeee
[20:09:41] <chupacabra> malcom2073, what you building?
[20:10:02] <malcom2073> Building? Nothing. Planning? Always stuff haha
[20:10:23] <chupacabra> i mean fooling with now.
[20:11:12] <malcom2073> Fiddling with a large format router design
[20:11:21] <chupacabra> ahhh
[20:11:36] <chupacabra> for making what?
[20:11:58] <malcom2073> I want to start taking on commercial work, signs, cabinets, etc
[20:12:07] <malcom2073> so I'm designing a 5x10 aluminum cutting router
[20:12:33] <chupacabra> cool. is alum strong enough?
[20:12:56] <chupacabra> i come from the maheenite era
[20:12:57] <malcom2073> It's made of steel, I mean capable of cutting aluminum
[20:13:08] <chupacabra> ahhh cool
[20:14:09] <chupacabra> I made buttloads of DC? cockpit panels and cockpit stuff.
[20:14:19] <malcom2073> Ah nice, making a sim?
[20:15:08] <chupacabra> worked for sim makers once. was great work but mostly for Boeing for DC-10s and stuff
[20:16:01] <chupacabra> Flight sim work was the best fun I ever had. lots of engineering by the machinists
[20:16:43] <chupacabra> got to ride in Simulators lots too. I can fly any of them
[20:34:56] <witnit> chupacabra: pictures?
[20:35:06] <witnit> of the machines :)
[20:35:57] <Loetmichel> chupacabra: i once did a few lit perpex cocpit panels for a customer...
[20:36:07] <Loetmichel> ... MANY years ago
[20:36:15] <Loetmichel> let me see if i find pictures
[20:38:16] <Loetmichel> nope, didnt made once it seems
[20:38:53] <Loetmichel> they were simple 4mm acrylic plates, spraypainted black from one side
[20:39:36] <Loetmichel> and then engraved and milled from the back (black) side to fit various switches and had text for it
[20:39:52] <Loetmichel> like this THW logo i made for a friend:
http://www.cyrom.org/palbum/main.php?g2_itemId=4979&g2_imageViewsIndex=1
[20:40:20] <Loetmichel> ... so the customer had PCBs with the switches and orange/white leds in between
[20:40:47] <Loetmichel> and when assebled it looked exactly like the light tableaus/switch tableaus in an A320 ;)
[20:46:35] <malcom2073> Loetmichel: I'm gonna be fiddling around with the sprayed acrylic engraving thing soon
[20:46:43] <malcom2073> Then backlight it so the engraved/drilled part comes through
[20:47:43] <witnit> I got this job I need to quote, anyone familiar with turning 304ss I could use some indexable insert suggestions. EAU is 200,000.
http://postimg.org/image/bs9whayl9/
[20:55:21] <witnit> probably more than anything I need opinions on rake and edge geometry for doing this in a single pass, I suspect I will be building my own insert holder to accommodate this cutter
http://tinyurl.com/gsp43oy
[21:02:39] <jdh> what's an EAU
[21:03:27] <witnit> Estimated Annual Usage
[21:04:14] <witnit> basicly I need to figure out a way to run 304SS and not have to babysit the machine
[21:04:28] <jdh> screw machine?
[21:04:32] <witnit> yeah
[21:05:11] <witnit> Im just not that comfortable with 304 yet. but I will be running it on a very solid single spindle machine
[21:57:04] <CaptHindsight> I've been milling SS304 on and off the past few weeks
[21:57:30] <CaptHindsight> likes sharp and hard tools with flood coolant
[21:57:45] <CaptHindsight> I only have problems if it gets hot
[22:36:03] <CaptHindsight> witnit: ^^
[22:39:18] <zeeshan> CaptHindsight: which alloy
[22:39:22] <zeeshan> 304L
[22:39:25] <zeeshan> or 304H
[22:41:48] <CaptHindsight> actually both, plate, rod and shapes
[22:44:23] <chupacabra> no pics. was just work then.
[22:44:31] <CaptHindsight> made the mistake of surface grinding a part before I drilled and tapped
[22:44:55] <zeeshan> lol
[22:45:34] <chupacabra> 304 is pretty hard alright
[22:45:52] <chupacabra> work hardens badly too
[22:46:25] <CaptHindsight> yesterday I was milling some with a 2 vs 4 flute HSS
[22:47:40] <CaptHindsight> now I need a bigger surface grinder, seems every new project has parts 2" longer than the travel of the tools
[22:48:20] <CaptHindsight> so from now on I'm going big or going home :)
[22:49:01] <CaptHindsight> even if the machine sits for months i hate getting stuck having to rotate or flip parts
[22:49:35] <chupacabra> yup
[22:54:55] <chupacabra> a part I made lots of. 17-4 Ph6 stainless hardened.
http://riecilla.com/node/3
[22:55:38] <chupacabra> that thing will be here lots longer than I
[22:56:53] <CaptHindsight> t12:
https://www.twistbioscience.com/about/ doyahknow they guys?
[22:57:01] <CaptHindsight> they/these
[22:57:03] <t12> i know much about them
[22:57:05] <t12> from a uh
[22:57:13] <t12> from intel/being the competition at least
[22:57:17] <t12> the reality is very unclear
[22:57:28] <CaptHindsight> http://spectrum.ieee.org/biomedical/devices/dna-manufacturing-enters-the-age-of-mass-production
[22:57:39] <t12> maybe io
[22:57:50] <t12> maybe i'm continuing the company position after its death
[22:58:06] <t12> but i've yet to talk to someone who has recieved and verified dna from them
[22:58:15] <t12> i've talked to lots of people who have had meetings about buying/beta program/etc
[22:58:45] <CaptHindsight> I'm going to start making some printers/synthesizers and the tools to make them
[22:58:57] <CaptHindsight> too many patents
[22:59:29] <t12> their org stuff was all inkjet
[22:59:39] <t12> i believe it still is inkjet on the dispense
[22:59:44] <t12> s/org/orig
[23:00:09] <CaptHindsight> going to be down in the femtoliter drop range
[23:00:39] <t12> i believe they got it to the point where they needed to control gas conditions during reaction
[23:01:16] <CaptHindsight> been watching CRISPR suddenly get popular as well
[23:01:26] <t12> it is very popular
[23:01:29] <t12> it is also very hard to use
[23:01:41] <t12> it will get easier over the next like 5-10 years
[23:01:48] <CaptHindsight> what1? they are DIY kits :)
[23:01:53] <CaptHindsight> yeah
[23:02:07] <CaptHindsight> need to make the tools to make the tools
[23:02:08] <t12> everyone doesnt like to admit the failure rate
[23:02:21] <t12> and the spending 1-2 years just spinning up to reproduce a CRISPR expirement
[23:02:47] <t12> it does make some targeted things possible that were very hard
[23:03:04] <t12> you still have a large effort of verification, selection, etc post-crispr
[23:03:09] <CaptHindsight> what I see is lots of biochemists and biologists trying to build nanomachines
[23:03:15] <t12> in what sense
[23:03:20] <CaptHindsight> a bit out of their realm
[23:04:42] <t12> maybne i'm too cynical but
[23:04:50] <t12> like you know how people first get into cnc stuff
[23:05:06] <t12> and they're like omg i must build my own stepper controller and machine and kickstart it and if only the whole world had these machines!
[23:05:16] <CaptHindsight> like all the Doc's that contact me about polymers or machines they are trying to build, great docs but not so much as chemists or engineers
[23:05:23] <t12> before being enough years in it to really understand
[23:05:28] <t12> i think the focus on dna production is like that
[23:05:38] <t12> its early in the chain of $ blockades to a bio project
[23:05:53] <t12> and people makign stuff have a tendency to focus on it before having enough field knowledge to know whats downstream
[23:06:01] <CaptHindsight> what? you mean you can't make cnc machines out of cat turds!
[23:06:20] <chupacabra> lol
[23:06:46] <t12> i guess some people are successful at turning that into $ after kickstarter
[23:06:50] <t12> like maybe othermill
[23:06:54] <t12> i just dont get why its so whatever
[23:07:00] <t12> cause they reduced the pricepoint a little?
[23:08:04] <CaptHindsight> I'm just tired of waiting for this in my lifetime
[23:08:30] <CaptHindsight> I don't want to get too old to see it
[23:08:41] <t12> my fav ceo stage
[23:08:47] <t12> is the i won all the money now i need to cure death phase
[23:08:53] <chupacabra> 700 is a lot easier than 700,000 Just got to make price effective.
[23:10:06] <CaptHindsight> all the talent seems to have left silicon valley
[23:10:22] <CaptHindsight> grew old, got into finance, went fishing
[23:11:00] <chupacabra> chilling in south austin
[23:12:02] <t12> theres a lot of talent
[23:12:04] <t12> its just dif talent
[23:12:19] <t12> theres ALOT of talent there is no marketing over, nobody talks about, they dont self-publicieze
[23:12:22] <chupacabra> i did all that and less. but im back. Cheap cnc machines will do it for me.
[23:13:20] <chupacabra> the best Silicon talent keeps killing themselves. worrisome
[23:14:01] <CaptHindsight> the light that burns twice as bright burns out twice as fast :)
[23:14:13] <chupacabra> so true
[23:14:28] <chupacabra> im glad i only went 66%
[23:14:37] <chupacabra> still here
[23:15:10] <witnit> zeeshan: the print simply says 304
[23:15:21] <chupacabra> i waste a lot of my brain cells about the human condition
[23:15:48] <chupacabra> ya, 304 is pretty generic.
[23:15:53] <witnit> I ordered 1 bar of 5/16 304l for testing
[23:16:03] <chupacabra> but can be different in the same batch
[23:16:24] <chupacabra> 1 bar should be the same all over
[23:16:52] <chupacabra> - a ball bearing melted in or two.
[23:18:32] <chupacabra> always amazed me. MAC dril 304 for months just the same and one foot of 1 bar cant be drilled and one loses 3 drills
[23:19:40] <chupacabra> once that foot is gone all is well for 6 months
[23:22:32] <Jymmm> then chop off the other foot?
[23:22:40] <t12> i wonder if you can detect that just by sound
[23:22:49] <t12> where the hard spot begins/ends
[23:22:53] <Jymmm> The screaming
[23:23:05] <t12> nah just by ringing the bar
[23:23:11] <Jymmm> lol
[23:24:33] <chupacabra> we had the supplier out looking with state of the art metal dectors and of course they never found anything. They bought new big drills. 3" if i remember right. 3" insert drills were high then
[23:25:09] <chupacabra> one could hear when the lathe hit the hard spot for sure.
[23:25:11] <CaptHindsight> art metal detectors :p
[23:25:27] <chupacabra> four big noises then the drill broke
[23:26:19] <chupacabra> just like the sound a ball bearing in a casting would sound
[23:26:21] <witnit> chup, what kind of machine?
[23:26:32] <chupacabra> okuma howa.
[23:26:55] <chupacabra> 60/80 or some big sombitch
[23:27:11] <witnit> check this idea out, peizioelectric transducer, records the vibrations in the machine for a cycle right
[23:27:24] <witnit> then it compares the oncoming cycles
[23:27:37] <witnit> and shutsdown if it gets too much variation
[23:27:41] <chupacabra> they are getting all that stuff now
[23:27:55] <witnit> oh?
[23:28:02] <witnit> dang im always a day late
[23:28:02] <chupacabra> i just was saying never trust your supplier
[23:28:11] <witnit> right
[23:28:38] <witnit> well I had been ordering the same steel for decade plus 20klbs at a time and thats a constant but I hear 304 is not so much like that
[23:28:50] <chupacabra> ya, me too. If I can think of it it has been done.
[23:28:58] <chupacabra> sept flying cars
[23:29:16] <witnit> well, yeah but thats alot of work
[23:29:20] <CaptHindsight> witnit: mine is from Metal Supermarkets, the labels are from various mills
[23:29:50] <CaptHindsight> and the bar and plate do behave differently when cutting
[23:30:09] <chupacabra> 20 lbs aint nothing. 1 ton a day is good volume to get some play with dealers
[23:30:32] <witnit> 20Klbs
[23:30:44] <chupacabra> oh ok.
[23:31:25] <chupacabra> i want to stay with non metals for a while. cut enough stainless
[23:31:37] <witnit> CaptHindsight: do you have a preferred mill? I would probably not care since the parts are so small the material cost will not be vast
[23:32:00] <chupacabra> besides my little alum frame machine aint gonna do it.
[23:32:14] <chupacabra> http://riecilla.com/node/3
[23:32:37] <CaptHindsight> there are a few distributors in and around Chicago, I don't buy enough to go direct to a mill
[23:32:42] <chupacabra> i like fadal for sure
[23:33:18] <chupacabra> good american at least when i was buying them
[23:33:33] <CaptHindsight> and the Metal Supermarket near me supplies McMaster and Grainger
[23:33:51] <CaptHindsight> so I get pretty good prices on small quantities
[23:34:00] <chupacabra> mori sieki, okuma howa. mitsubishi
[23:34:27] <CaptHindsight> need a good used working cnc lathe?
[23:34:41] <chupacabra> I learned on Hurco and they still easy
[23:34:48] <witnit> capt which one?
[23:34:52] <chupacabra> Mazak
[23:34:55] <witnit> barloader?
[23:35:19] <chupacabra> i always made my own bar feed.
[23:35:28] <witnit> 12'? =D
[23:35:37] <chupacabra> they cost too much.
[23:35:42] <CaptHindsight> witnit: where are you located?
[23:35:42] <witnit> I made a 12' for my hardinge
[23:35:47] <witnit> ft wayne indiana
[23:36:01] <chupacabra> just as easy and almost free to get a bar puller
[23:36:12] <witnit> bar pull is slow
[23:36:15] <chupacabra> austin texas
[23:36:36] <CaptHindsight> witnit: what size do you need?
[23:36:38] <chupacabra> slowvsfree....????
[23:36:59] <chupacabra> i got no lathe now
[23:37:35] <CaptHindsight> http://www.ebay.com/itm/Okuma-LSF15-2SP-CNC-Lathe-/181853874464 $4,500 or best
[23:37:51] <chupacabra> also when a bar feeder fucks up it fucks up tools on lathe. puller not
[23:39:39] <chupacabra> nice price. put linuxcnc on it. prolly drivers gone
[23:39:54] <CaptHindsight> http://www.ebay.com/itm/OKUMA-CADET-L1420-15-POWER-CHUCK-X-53-CC-APPROX-LONGBED-CNC-LATHE-/201494056666
[23:39:54] <chupacabra> offer 2
[23:40:48] <CaptHindsight> http://www.ebay.com/itm/Mazak-SlantTurn-35-ATC-MC-Automatic-Tool-Changer-CNC-Lathe-1988-/321956179029 4,299 or best
[23:41:56] <chupacabra> that one better if big enough. one can always run smaller parts on big machines. not the other way.
[23:43:10] <chupacabra> other was double headed, right?
[23:43:22] <CaptHindsight> unless you have a lathe stretcher
[23:43:37] <witnit> I have looked at those one exactly :)
[23:43:50] <chupacabra> cant beat completed parts coming off a lathe.
[23:44:56] <CaptHindsight> witnit: the OKUMA CADET L1420 has a reserve, not sure how high
[23:45:19] <chupacabra> dont let me guide you. I bought a clawfoot tub from Utah on auction. shipping is 6 times cost
[23:45:19] <CaptHindsight> it's the only one that completely works
[23:46:01] <chupacabra> i ran a cadet. It was nice. small if i remember
[23:46:16] <CaptHindsight> also depends on what parts are missing from the two Okuma LSF15
[23:46:38] <chupacabra> is it two headed?
[23:47:57] <chupacabra> doesnt really matter tooling up is expensive. they prolly giving that away in another auction.
[23:49:26] <chupacabra> I was drilling for oil for 100 a day before joining the navy in 1972. Been a machinist since.
[23:49:47] <chupacabra> still drilling for something
[23:49:54] <CaptHindsight> heh
[23:50:28] <t12> now you put oil back in holes
[23:50:29] <chupacabra> how old you, hindsight
[23:50:44] <chupacabra> i wish i could
[23:50:58] <chupacabra> i put my spunk
[23:51:24] <chupacabra> gotta be old to have that moniker
[23:51:42] <t12> i finally got access to a university shop again
[23:51:44] <t12> this time a NEW shop
[23:51:47] <t12> also neglected
[23:51:53] <CaptHindsight> new tools?
[23:51:56] <t12> but 2 bridgeport-alikes, 2 small lathes
[23:52:09] <t12> nice general tools, lots of metal stock, lots of misc old tooling
[23:52:30] <t12> gotat whip everything back into shape
[23:53:17] <t12> they might actually get the cash to get some fte's to work in it, amazingly
[23:53:27] <t12> so if that pays well enough i'd prolly do that job
[23:53:56] <witnit> the lfs 2sp hmmmmmm
[23:54:53] <CaptHindsight> http://chicago.craigslist.org/nch/bfs/5384527024.html Machine Shop Closed
[23:55:03] <chupacabra> you working there?
[23:56:07] <chupacabra> i have a good friend works at UT austin main machine shop. Nice digs
[23:56:24] <CaptHindsight> nope
[23:56:25] <t12> yeah i've been working variously for the university for like
[23:56:28] <t12> 8? 9? years now
[23:56:39] <CaptHindsight> I'm currently making some things for UT Austin
[23:56:41] <t12> mainly computer stuff but really (stupidly) migrating away from it
[23:57:12] <t12> we had multiple shops, and as stuff changed they laid off anyone in the shops and they sat idle for like.... 10 years
[23:57:20] <t12> now they have noone who knows how to use them
[23:57:30] <t12> and increasing stuff that needs to be made, usually simple stuff
[23:57:36] <CaptHindsight> like a rotary phone
[23:57:58] <t12> simple jobs are nice
[23:58:05] <t12> then i can hang out with the scientists more
[23:58:08] <Jymmm> Who was making a rocket stove?
[23:58:38] <CaptHindsight> rocket thats a stove or a stove that is a rocket?
[23:58:46] <t12> low earth orbit stove
[23:58:59] <Jymmm> CaptHindsight: Yes
[23:59:21] <t12> ever look through SBIR?
[23:59:31] <CaptHindsight> capable of delivering a pizza or few Kg warhead
[23:59:33] <chupacabra> any machine one could want to get checked out on
[23:59:34] <chupacabra> i should tell George L that UT is jobbing shit out. He prolly say, "GOOD"
[23:59:35] <chupacabra> t12. let me in on the contract
[23:59:43] <Jymmm> $6 rocket stove
