[00:00:10] <Snuggy> Running the 'Vair stuff - 3.27 'rear' opposed to the stock like 5.37s...
[00:00:28] <somenewguy_shp> but then I forgot one of the valve springs at the house so I aint closing the upper end today and figured I needed to get somethign done
[00:00:40] <zeeshan> doh
[00:00:41] <zeeshan> :P
[00:00:53] <zeeshan> my cars on jack stands :{
[00:00:56] <somenewguy_shp> found a stud, now need to konw if its long enough
[00:01:09] <somenewguy_shp> mines been on stands for a looong time, ate a valve guide
[00:01:16] <zeeshan> haha
[00:01:18] <somenewguy_shp> been using my manx buggy as a daily driver for 2 months
[00:01:28] <somenewguy_shp> lets just say its a good thing I have a high tolerance for the cold
[00:01:42] <Snuggy> Yikes! Hope it wasn't snowing!
[00:01:57] <somenewguy_shp> only a couple days lol

[00:02:26] <somenewguy_shp> now if the stars are .really. in my favor its a blind hole and bobs my mothers brother
[00:02:29] <XXCoder> somenewguy_shp: lol once had my car with broken signal lights. had to hand signal in really bad weather for weeks
[00:02:34] <XXCoder> then finally fixed it
[00:02:53] <XXCoder> had to go college with wel left arm lol
[00:02:56] <XXCoder> wet
[00:03:07] <somenewguy_shp> sounds like my 77
[00:03:14] <Snuggy> Alright...I'm gettin in the crib. I gotta work tomorrow to pay into the welfare system to support you slackers...
[00:03:18] <somenewguy_shp> electrical was never all that well behaved after i got rearended
[00:03:20] <Snuggy> :) LOL!!!!!!
[00:03:28] <zeeshan> THANK YOU SNUGGY!
[00:03:29] <zeeshan> :DS
[00:03:43] <somenewguy_shp> you mean ur not working right now?
[00:03:44] <Snuggy> Nite Gents - keep the shiny side up!
[00:03:54] <somenewguy_shp> HOW WILL I PAY FOR MY NEXT CAR YOU SELFHISH JERK
[00:03:58] <somenewguy_shp> nite
[00:04:03] <XXCoder> lol Snuggy
[00:04:26] <XXCoder> think ill go sleep too. lots clamps to do tomorrow.
[00:04:41] <XXCoder> bottling up air lol
[00:05:07] <somenewguy_shp> cant let it get out now
[00:05:22] <somenewguy_shp> i think I'm gonna swap machines anyways, get some "real" work done lol
[00:05:36] <somenewguy_shp> these boards aint gonna design themselves
[00:05:36] <XXCoder> lol well night
[00:05:47] <CaptHindsight> working on the edge detection http://imagebin.org/309199 http://imagebin.org/309105 http://imagebin.org/309193
[00:05:55] <somenewguy_shp> goodnight nitevale
[00:06:01] <WalterN> CaptHindsight: ohi
[00:07:04] <WalterN> CaptHindsight: ordered and received all that electronic stuff, now I just need to set up my electronics table and start microcontroller programing
[00:07:08] <somenewguy_shp> ool, whos that going for you?
[00:07:33] <WalterN> what?
[00:07:38] <somenewguy_shp> CaptHindsight: not sure what you're doing, but I saw some really cool stuff with edge detection not too long ago
[00:07:45] <CaptHindsight> WalterN: whatcha werkin on?
[00:08:10] <WalterN> CaptHindsight: single axes feeder for a bandsaw to make it automatic
[00:08:15] <somenewguy_shp> color vs hue and all that fun stuff to make shadows less of an issue, but it looks like you don't quite have that problem
[00:08:28] <WalterN> horizontal bandsaw
[00:08:42] <CaptHindsight> somenewguy: camera based edge and feature detection for auto ZERO
[00:09:28] <CaptHindsight> well thats how most linuxcnc users would use it
[00:10:21] <CaptHindsight> but I'm actually working on auto feature and defect detection
[00:10:53] <somenewguy_shp> man i dig living in the future
[00:11:04] <CaptHindsight> those were just pics using a cheapo usb vga microscope
[00:11:39] <WalterN> writing computer software is not my thing
[00:11:52] <WalterN> microcontroller programming is rather fun though
[00:12:37] <WalterN> (not that I'm any good at it... heh)
[00:12:42] <somenewguy_shp> WalterN: its addictive, its like problem/puzzle solving
[00:12:44] <CaptHindsight> http://www.ebay.com/itm/200X-Portable-USB-Digital-5MP-4-LED-Microscope-Endoscope-Camera-with-Tripod-/251414807545 this one, it's actually VGA not 5MP, the lying scum!
[00:13:02] <somenewguy_shp> and the puzzle is much more limited in its complexity than "normal" computer programming
[00:13:21] <somenewguy_shp> poorly vetted facts on ebay? while I never!
[00:13:36] <CaptHindsight> http://imagebin.org/309060 6mil pcb trace
[00:14:09] <WalterN> somenewguy_shp: donno... I rather like the C language... most things on the computer are not programmed in C any more
[00:14:09] <CaptHindsight> http://imagebin.org/308973 taken 1" from lens to object
[00:14:53] <somenewguy_shp> I need one of those
[00:14:55] <CaptHindsight> I really dislike programming
[00:15:03] <somenewguy_shp> and yet..
[00:15:14] <CaptHindsight> I'd rather hold the wrong end of a soldering iron
[00:15:22] <WalterN> lol
[00:15:34] <WalterN> programming is a creative outlet
[00:15:56] <CaptHindsight> nobody else is going to do the image processing stuff
[00:16:06] <somenewguy_shp> waltern, same here, since I don't do anything too serious with it the hardest part is figuring out how to approach the problme, not how to effeciently use a language
[00:16:30] <somenewguy_shp> i play with micocontrollers and gcode for real basic stuff
[00:16:38] <somenewguy_shp> its just a slightly nerdier sudoku
[00:16:56] <WalterN> free-form tinker toys
[00:16:58] <CaptHindsight> I really don't mind 1's and 0's is all the abstraction that bugs me
[00:17:50] <WalterN> CaptHindsight: you like assembly programming then?
[00:18:16] <CaptHindsight> it's a toss up between having my nipples belt sanded
[00:18:24] <WalterN> lol
[00:19:04] <WalterN> the abstraction layer between 0's and 1's and assembly is very thin
[00:19:34] <CaptHindsight> yeah, after that it might as well be magic
[00:19:53] <WalterN> I can deal with C -> assembly
[00:20:00] <CaptHindsight> magic compilers
[00:20:01] <WalterN> but anything higher is meh
[00:20:12] <WalterN> java, python... so much magics
[00:20:41] <WalterN> alright, gotta cut one more bar
[00:20:59] <CaptHindsight> I can see why software barely works
[00:21:08] <CaptHindsight> like a house of cards
[00:21:11] <WalterN> well
[00:21:17] <WalterN> yeah... kinda
[00:21:46] <CaptHindsight> if machines were built the same way I'd be a Shepard
[00:21:50] <WalterN> most of it is really bad practices because large companies dont like to pay programmers to do it correctly
[00:22:13] <WalterN> they pay them to do it fast...
[00:22:35] <CaptHindsight> it's sociopaths in general, they don't see anything other than the quickest way to get the buck/money
[00:22:49] <WalterN> then they all vent, and code their own version of the software and make it open source
[00:23:05] <WalterN> they being the programmers being payed nothing
[00:23:26] <CaptHindsight> I'm waiting for the ape rebellion
[00:23:35] <WalterN> its coming
[00:24:19] <CaptHindsight> any movement on the SLS printer?
[00:24:59] <WalterN> no
[00:25:15] <WalterN> I've been so busy here at my shiny new shop...
[00:25:39] <WalterN> CaptHindsight: I'm 1/3 owner of this place
[00:26:16] <CaptHindsight> what do you do the other 2/3 of your time :)
[00:27:10] <WalterN> heh
[00:27:49] <CaptHindsight> http://www.newegg.com/Product/Product.aspx?Item=N82E16826104648 takes great shots at 1"
[00:28:08] <WalterN> oh hey, I have one of those
[00:28:19] <WalterN> ...somewhere
[00:28:21] <CaptHindsight> http://imagebin.org/308971 http://imagebin.org/308970
[00:30:27] <zeeshan> CaptHindsight:
[00:30:32] <zeeshan> is 6 mil .006" ?
[00:30:53] <CaptHindsight> yes or ~150um
[00:30:59] <zeeshan> ah
[00:31:00] <zeeshan> i didnt know that
[00:31:06] <zeeshan> so insterad of saying 10 thou
[00:31:09] <zeeshan> i can be saying 10 mil
[00:31:11] <zeeshan> :D
[00:31:16] <CaptHindsight> ~25um per 0.001"
[00:31:26] <WalterN> 25.4um?
[00:31:27] <zeeshan> learned something new :D
[00:31:33] <WalterN> :P
[00:31:38] <WalterN> zeeshan: same
[00:32:50] <WalterN> CaptHindsight: in the near future, I'd like to see two people here with the third taking the week off
[00:32:56] <WalterN> or something
[00:33:02] <zeeshan> http://www.wmctv.com/Global/story.asp?S=6668755
[00:33:07] <zeeshan> i hope pete wasn't at this car show
[00:33:08] <zeeshan> ;/
[00:33:13] <WalterN> too busy to do that just yet
[00:35:13] <CaptHindsight> http://en.wikipedia.org/wiki/Thousandth_of_an_inch
[00:38:13] <WalterN> oh man
[00:38:24] <zeeshan> ah
[00:38:24] <WalterN> costo muffins
[00:38:27] <zeeshan> so its mils
[00:38:29] <zeeshan> not mil
[00:38:30] <zeeshan> gotcha
[00:38:31] <WalterN> so good
[00:38:59] <CaptHindsight> singular vs plural
[00:39:04] <CaptHindsight> mil mils
[00:41:45] <CaptHindsight> huh, the new cold war is turning into a hot war
[00:41:53] <CaptHindsight> bbl
[00:42:22] <WalterN> rlly
[00:42:27] <WalterN> linky?
[00:43:02] <CaptHindsight> http://www.huffingtonpost.com/2014/05/05/slaviansk-ukraine-fightin_n_5266405.html
[00:43:50] <CaptHindsight> still internal, but I wonder how much it's going to spread
[00:43:54] <WalterN> nice splodie there in the background
[00:44:25] <WalterN> donno, I kinda hope it does... we need another good scale war
[00:44:50] <zeeshan> warrrrr
[00:44:54] <zeeshan> it fuels the economy
[00:45:16] <CaptHindsight> http://www.washingtonpost.com/world/ukraine-sends-police-unit-to-odessa-to-restore-order-after-separatists-raid-police-station/2014/05/05/f5c34f9e-d435-11e3-8a78-8fe50322a72c_story.html
[00:45:31] <CaptHindsight> Ukraine helicopter downed as fighting resumes
[00:46:09] <CaptHindsight> what will become of this planet if peace breaks out?
[00:46:37] <WalterN> a sadface from waltern
[00:47:25] <CaptHindsight> http://www.washingtonpost.com/posttv/national/fighting-erupts-on-outskirts-of-rebel-held-slovyansk/2014/05/05/386b47a2-d463-11e3-8f7d-7786660fff7c_video.html hehe better watch out they have sidecars!
[00:49:53] <WalterN> think open source image tracking software is good enough to go in super sonic missiles?
[00:50:32] <CaptHindsight> actually it is, have you seen any of the lower cost drones
[00:50:39] <WalterN> no
[00:51:13] <CaptHindsight> the algorithms have been around for decades
[00:52:09] <WalterN> one of the first things I did in the machine shop was design and build my own rocket engine
[00:52:28] <zeeshan> haha
[00:52:29] <zeeshan> thats cool
[00:52:31] <WalterN> been on the back burner for ~8 years, but I think I could do it
[00:52:36] <zeeshan> whatd you make it out of ?
[00:52:45] <WalterN> steel
[00:52:46] <CaptHindsight> http://en.wikipedia.org/wiki/MIM-104_Patriot
[00:52:51] <WalterN> yeah
[00:52:54] <WalterN> something like that
[00:53:12] <WalterN> only with modern stuff
[00:53:22] <WalterN> (butt tons cheaper... heh)
[00:54:13] <CaptHindsight> http://www.youtube.com/watch?v=3inpqS-2exo Fiber-Optic Guided Missile FOG-M
[00:55:14] <WalterN> I'd make a hybrid engine, wax or plastic and hydrogen peroxide, cheap and easy to get, and easy to refine if necessary
[00:55:43] <CaptHindsight> or more http://www.youtube.com/watch?v=B5VcnCZ6Pv0 Tomahawk Cruise Missile style?
[00:55:47] <WalterN> and it stores fairly well
[00:56:51] <CaptHindsight> I was just reading about the new changes to private drone use
[00:56:54] <WalterN> http://spathengineering.com/ I made a bunch of rocket engine parts for this guy, I still keep in contact with him as a friend
[00:57:07] <CaptHindsight> not sure if that covers model rocketry as well
[00:57:23] <CaptHindsight> especially guided rocketry
[00:57:42] <WalterN> model rockets have strict weight requirements
[00:58:00] <WalterN> under like 8oz or something
[00:58:07] <CaptHindsight> what if launched from a drone?
[00:58:12] <WalterN> donno
[00:58:20] <WalterN> guidance is unknown too
[00:58:25] <WalterN> or rather, undefined
[00:58:46] <WalterN> and I want to give an F16 a run for its money
[00:58:47] <CaptHindsight> http://motherboard.vice.com/read/the-us-government-is-trying-to-fine-a-drone-hobbyist-for-the-first-time-ever
[01:00:22] <WalterN> I figure if I actually manage to hit an F16, I'd either go to prison for life, or get ushered into the government steam engine making stuff
[01:01:01] <MattyMatt> it depend's whose F16 it is
[01:01:10] <WalterN> the one closest to me
[01:01:32] <CaptHindsight> http://www.cnn.com/2014/03/07/us/drone-pilot-case-faa
[01:01:35] <WalterN> though good point... maybe that would make for a good field trip
[01:01:49] <MattyMatt> to libya
[01:02:02] <WalterN> russia
[01:02:12] <MattyMatt> or wherever the MIC is flexing its muscles atm
[01:02:27] <WalterN> yeah
[01:02:51] <WalterN> an ICBM would be nice, but its kinda difficult to refine uranium, or related elements
[01:02:55] <CaptHindsight> http://science.slashdot.org/story/12/03/07/223255/amateur-rocketeer-derek-devilles-qu8k-rocket-flies-to-120000-feet-video
[01:03:08] <CaptHindsight> that is over 8oz!
[01:04:08] <WalterN> CaptHindsight: yeah, for stuff over 8oz, and other things, you call the FAA and tell them you are using the airspace for half a day or w/e, then they tell you no, do it the next day and we are all good
[01:04:20] <WalterN> basically
[01:04:55] <CaptHindsight> so not a hobby for the impatient
[01:05:32] <MattyMatt> it beats waiting for nasa
[01:05:41] <MattyMatt> I've been doing that since 69
[01:05:54] <WalterN> screw nasa
[01:06:17] <WalterN> they lost their usefulness at the end of apollo
[01:06:40] <zeeshan> WalterN: i agree
[01:06:48] <zeeshan> =[
[01:06:48] <MattyMatt> i called my rocket Achilles 1, because I kinda knew the paper nozzle would blow out first
[01:06:57] <zeeshan> hopefully with the mars missions
[01:06:59] <zeeshan> it'll change.
[01:07:12] <WalterN> not likely
[01:07:21] <WalterN> SpaceX is where the bets are
[01:07:22] <CaptHindsight> http://www.estesrockets.com/rockets/pro-series
[01:07:35] <CaptHindsight> no real money in it
[01:07:56] <CaptHindsight> so I don't expect much progress in space
[01:07:59] <MattyMatt> planetaryresources is where it's at
[01:08:10] <WalterN> coal is where the money is at :P
[01:08:19] <zeeshan> CaptHindsight: be open minded :P
[01:08:25] <WalterN> though, helium3
[01:08:40] <MattyMatt> plant a flag on an asteroid, then sell nickel futures
[01:08:41] <zeeshan> almost the whole world at the time of some of the greatest pioneers
[01:08:44] <zeeshan> said similar stuff :P
[01:09:14] <CaptHindsight> can we send the banksters into space?
[01:09:24] <MattyMatt> half of them
[01:09:30] <zeeshan> honestly, the way i think of it is like this
[01:09:31] <WalterN> start with congress
[01:09:39] <MattyMatt> bottom half would be funniest
[01:09:42] <zeeshan> we have finite amount of resources, and to let the economy grow
[01:09:59] <zeeshan> we'll eventually need to venture off
[01:10:01] <WalterN> zeeshan: I'd disagree
[01:10:06] <WalterN> well
[01:10:11] <WalterN> kinda
[01:10:18] <zeeshan> i'm not thinking immediately in our lifetime
[01:10:18] <CaptHindsight> before they melt the place?
[01:11:09] <zeeshan> man
[01:11:17] <zeeshan> imagine running a milling machine in space
[01:11:28] <zeeshan> you can load a 10,000 lb part in the chuck like it was a joke
[01:11:29] <zeeshan> :D
[01:11:34] <WalterN> the post apcoliptic garbage about turning the planet into husk will never happen though, biological resources will _always_ be around
[01:11:38] <zeeshan> and go from a 4 jaw to 3 jaw easily
[01:11:49] <MattyMatt> inertia is the same
[01:11:59] <zeeshan> inertia is same yes
[01:12:02] <zeeshan> but there is no gravity
[01:12:08] <zeeshan> so you can easily float parts into position
[01:12:22] <zeeshan> but iguess when you're cutting metal
[01:12:26] <zeeshan> chips and fluid will be a nightmare
[01:12:26] <zeeshan> haha
[01:12:34] <CaptHindsight> it's getting them to and from that gets expensive and difficult
[01:12:41] <MattyMatt> by pushing them? if it's a big part, you'll be pushing yourself away more
[01:12:45] <WalterN> zeeshan: yeah, I've been thinking about that... how to run a lathe in space
[01:13:06] <CaptHindsight> well whats the lathe attached to?
[01:13:15] <WalterN> I havent thought of a good way to deal with coolant/chips
[01:13:16] <CaptHindsight> or is this a free floating lathe?
[01:13:17] <MattyMatt> when the head goes left, the bed goes right
[01:13:54] <CaptHindsight> wall mount :)
[01:14:17] <zeeshan> hahaha
[01:14:22] <zeeshan> wall mount. love that joke
[01:14:26] <WalterN> also, http://en.wikipedia.org/wiki/Project_Orion_%28nuclear_propulsion%29
[01:14:41] <MattyMatt> you couldn't afford to waste chips, and anyway they'd be a navigation hazard
[01:14:55] <CaptHindsight> space junk
[01:15:01] <zeeshan> i'd love to do my machining upside down
[01:15:35] <CaptHindsight> http://www.space.com/16518-space-junk.html
[01:15:42] <WalterN> zeeshan: until a coolant blob loaded with chips hits you in the arm/face/leg
[01:15:49] <zeeshan> :D
[01:15:58] <WalterN> and it just sticks
[01:16:03] <WalterN> no dripping off
[01:17:16] <CaptHindsight> Over 21,000 pieces of space trash larger than 4 inches (10 centimeters) and half a million bits of junk between 1 cm and 10 cm are estimated to circle the planet.
[01:17:38] <zeeshan> i bet some of that is human poop
[01:17:39] <zeeshan> :p
[01:17:43] <CaptHindsight> and thats before a space lathe
[01:17:55] <MattyMatt> in space, additive is easier. spray metals with electrons or lasers
[01:18:29] <zeeshan> yea but some components need to be metal
[01:18:33] <WalterN> thats true too
[01:18:34] <zeeshan> and need a crazy surface finish
[01:18:38] <WalterN> zeeshan: metal SLS
[01:18:41] <CaptHindsight> More than 500,000 pieces of debris, or “space junk,” are tracked as they orbit the Earth.
[01:18:50] <CaptHindsight> http://www.nasa.gov/mission_pages/station/news/orbital_debris.html
[01:18:53] <zeeshan> yea, but metal sls doesnt leave a good surface finish
[01:19:02] <zeeshan> and isn't that accurate
[01:19:13] <zeeshan> from the videos ive seen, you still need machining on journal bearing surfaces
[01:19:21] <zeeshan> or press fits
[01:19:26] <MattyMatt> you can spray all metals, and diamond for windows. that's 90% of your structural requirements
[01:19:31] <WalterN> CaptHindsight: if they made that 1950's-1960's Orion, they would not have to worry about junk floating in space
[01:20:07] <WalterN> 5 story 10,000ton space ship
[01:20:09] <CaptHindsight> after trying everything else first they usually do the right thing
[01:20:22] <WalterN> using cutting edge nuclear propulsion
[01:20:42] <WalterN> dirt cheap to put stuff in space with
[01:21:17] <WalterN> its still the best way
[01:21:30] <WalterN> the united states government is so stupid
[01:22:18] <WalterN> heerrrrr, lets build a space shuttle thing
[01:22:32] <WalterN> yayscience
[01:22:45] <WalterN> idiots
[01:23:13] <WalterN> president nixon and congress at the time
[01:23:43] <WalterN> that was before I was born
[01:24:10] <MattyMatt> if the energia hadn't exploded, there could've been a shuttle race
[01:24:12] <WalterN> (I'm ranting slightly more than I intended)
[01:24:55] <MattyMatt> mind you, buran woulda probably screwed the soyuz production, and we'd have lost that too
[01:25:56] <WalterN> what?
[01:26:37] <MattyMatt> if the russians had piled all-in on shuttles
[01:26:54] <WalterN> oh
[01:27:15] <WalterN> shuttles are rather worthless... too much weight to be useful
[01:27:30] <WalterN> von braun and his buddies knew what they were doing
[01:27:50] <MattyMatt> yeah but too much weight to retire on the ground, when they had the choice of mothballing them in orbit
[01:28:25] <WalterN> the problem is chemical based rockets dont scale, thats why the orion project popped up
[01:29:14] <MattyMatt> chemical rockets don't take kindly to mothballing, when fueled
[01:29:43] <WalterN> by the time apollo was at the end of its life span, felix dyson and nuclear science buddies were ready to build (after scale testing) Orion
[01:30:31] <WalterN> they presented it to nixon and congress, but congress decided they could do better, and went with the shuttle, and micromanaged its design
[01:31:08] <WalterN> (short version of the fall of NASA)
[01:32:13] <WalterN> its kind of a really sad story... :-/
[01:32:54] <MattyMatt> it's at the part with the violins, before the car chase
[01:33:18] <WalterN> meh
[01:33:21] <MattyMatt> nasa's biggest problem was that it crowded out private enterprise
[01:33:45] <WalterN> enh
[01:33:48] <MattyMatt> so maybe now, it'll really shine
[01:34:06] <MattyMatt> taking public money and buying COTS stuff
[01:34:17] <WalterN> in the apollo days they defined basic computer systems... the way memory and electronics work
[01:34:30] <WalterN> that are standard practice today
[01:34:51] <MattyMatt> that probably all came from air force and navy. remember how nasa started
[01:35:53] <MattyMatt> nukes got compact, so the navy had some obsolete oversize rockets, so they formed naca specifically to play with those
[01:35:55] <WalterN> kinda... I guess you could say it started with advanced WW2 radar instillations... but w/e
[01:36:26] <WalterN> oh you mean the rockets?
[01:36:33] <MattyMatt> if you believe AC Clarke, it did :)
[01:37:37] <MattyMatt> it freaks me out they had mosfets in WW2
[01:37:41] <WalterN> well, there was more than one factor.. von braun worked for the military for ~5-10 years, before NASA started, but von braun kind of hated it... I'm sure that was a major factor too (spuntnick aside)
[01:37:57] <MattyMatt> it musta bugged them when deforrest patented bjt
[01:38:18] <WalterN> (not sure what bjt is... but alright)
[01:39:01] <MattyMatt> bipolar transistor BPT or whatever (on first coffee)
[01:39:03] <WalterN> also, basically all of the vacuum tubes are mosfet style... just really high power versions :P
[01:39:54] <WalterN> or am I thinking of a specific class of vacuum tube?
[01:40:09] <WalterN> I dont remember exactly :-/
[01:40:23] <WalterN> I don't get payed enough to know this stuff
[01:40:28] <MattyMatt> I never bothered to learn much about tubes. I kinda regret that
[01:41:08] <WalterN> I think most vacuum tubes are field effect
[01:41:13] <MattyMatt> gotta prune the knowlege. no puny human brain can contain everything anymore
[01:41:19] <WalterN> just not solid state
[01:42:35] <WalterN> they did have solid state simi-conductors in WW2 times... mostly revolving around quarts crystal, but still... nobody really had the time to study it
[01:44:56] <WalterN> that and interesting things going on with radar
[01:45:15] <MattyMatt> back to the subject of our own rockets. are these cheap mems gyros designed to cack out when used in a real threat missile?
[01:45:34] <WalterN> mems?
[01:45:45] <WalterN> you can get solid state gyros
[01:45:49] <MattyMatt> micro EM systems
[01:46:09] <WalterN> oh, I think we are talking about the same thing then?
[01:46:28] <MattyMatt> only solid state one I know is laser ones, and they are not cheap enough for a small afghan boy to buy
[01:47:43] <WalterN> you mean something like this? https://www.sparkfun.com/products/10937
[01:47:59] <MattyMatt> those are mems
[01:48:11] <MattyMatt> laser ones are usually triangular
[01:48:22] <WalterN> donno
[01:48:38] <WalterN> datasheet should say what kind of acceleration they should be able to handle
[01:48:43] <MattyMatt> mems is a silicon chip, etched to exhibit mechanical features
[01:49:46] <MattyMatt> yeah but the datasheet and secret military threat assessment are 2 different things. they have gotta have considered how to limit them, before letting civilians buy them
[01:50:09] <MattyMatt> you'd think
[01:50:53] <MattyMatt> if not, don't blame me when a combo of nintendo and estes brings down an airliner
[01:51:19] <WalterN> donno... I do know a guy to ask though, who does
[01:51:32] <WalterN> GPS is like that
[01:51:38] <WalterN> well, kinda
[01:51:58] <WalterN> not designed to break down under a load, just update times are slow
[01:52:16] <MattyMatt> you can't even buy 3% peroxide here anymore
[01:52:40] <MattyMatt> since the london bombs
[01:52:48] <WalterN> where is here? cause I called around and it seems like its easy to get 50% for industrial purposes
[01:53:19] <MattyMatt> UK
[01:53:25] <WalterN> oh yeah
[01:54:01] <MattyMatt> I say can't, but I'm always assuming I wouldn't pass the vetting
[01:54:12] <WalterN> there is a place that will make 80% and ship it to me via a tanker truck... I just have to provide the money and storage ability
[01:54:56] <WalterN> laws in USA suck, but the rest of the world still sucks more
[01:55:27] <MattyMatt> amazon.co.uk stock kg bags of saltptre, frequently bought together with flowers of sulpher. I'm tempted to order some, just to assess the bearocracy, but that's silly
[01:55:41] <WalterN> heh
[01:55:55] <WalterN> probably easier to make your own over there
[01:56:10] <MattyMatt> if you've got your own mud wall to piss on
[01:56:47] <WalterN> can you even get liquid oxygen?
[01:56:53] <WalterN> without hassle
[01:57:58] <MattyMatt> yeah there was a monopoly on all transportable gas in UK, which still dominates
[01:58:14] <WalterN> was?
[01:58:18] <WalterN> oh
[01:58:26] <WalterN> but is it a hassle?
[01:58:28] <MattyMatt> a lot of paperwork and rules, but the systems are in place to get it
[01:58:32] <MattyMatt> yep
[01:58:46] <WalterN> stupid
[01:58:55] <WalterN> and why I wont move from USA... yet
[01:59:17] <MattyMatt> go up, young man
[01:59:30] <WalterN> enh
[01:59:45] <WalterN> no
[01:59:48] <MattyMatt> land on the moon, plant your own flag
[02:00:04] <WalterN> oh
[02:00:07] <WalterN> sure, why not
[02:00:18] <WalterN> SpaceX will probably get there first though
[02:01:01] <MattyMatt> they'll probably honour the treaty USG have signed
[02:01:24] <MattyMatt> which prevents them claiming any or all of the moon
[02:02:39] <MattyMatt> that treaty will last until there are exactly 2 parties there permanently :)
[02:02:45] <WalterN> the moon has a better internet connection than I have
[02:03:15] <MattyMatt> it still bugs me that they chose .moon TLD instead of .luna
[02:03:24] <WalterN> lol
[02:03:29] <WalterN> luna
[02:04:22] <WalterN> like this kind of luna? http://img2.wikia.nocookie.net/__cb20120713100438/mlp/images/c/cd/FANMADE_Princess_Luna_transparent_background.png
[02:04:24] <WalterN> :P
[02:04:59] <MattyMatt> no bro
[02:06:00] * MattyMatt bronacker
[02:06:09] <WalterN> ..?
[02:06:44] <MattyMatt> I'm a bloke who like ponymeat sandwiches, and unicorns >:)
[02:06:50] <WalterN> heh
[02:06:56] <WalterN> I'm fine with that too
[02:07:40] <MattyMatt> I did see an awesome "unicorn poop cookies" on youtube that made me wish I was a 6yo girl for a few seconds
[02:08:22] <WalterN> canned unicorn meat
[02:08:47] <WalterN> http://www.thinkgeek.com/product/e5a7/
[02:10:40] <MattyMatt> awesome. now I wish I had a 6yo girl to buy presents for
[02:11:52] <WalterN> I do admit though, I am kind of a fan of the generation 4 my little pony show... probably because of the scope the show covers that most cartoons dont

[02:14:17] <Deejay> huhu witnit
[02:18:13] <WalterN> heh, MattyMatt stops talking :P
[02:20:15] <MattyMatt> rockets was quite far enough OT :)
[02:20:27] <WalterN> you are no fun
[03:29:15] <Valen> did i miss rockets?
[03:29:19] * Valen is a rocket person
[03:29:21] <Valen> :-<
[04:24:11] <tom_R2E3> hello #linuxcnc
[04:24:56] <tom_R2E3> is there a "how to" to assign keyboard keys to new functions somewhere?
[04:32:31] <WalterN> Valen: seems so
[04:33:17] <WalterN> eventually some day I'm going to build a largish one
[05:06:50] <archivist> tom_R2E3, yes in an email
[05:07:25] <archivist> http://article.gmane.org/gmane.linux.distributions.emc.user/12642
[06:51:20] <MrSun_> hmm, anyone tried the xhc-hb04 code in the linuxcnc tree ?
[06:51:32] <MrSun_> got it working somewhat but getting alot of bitching from linuxcnc ...
[06:51:42] <MrSun_> cant start programs from the pendant etc :/
[06:51:54] <MrSun_> not allowed in manual mode, and not allowed in mdi mode ..
[06:54:16] <jthornton> tis true you can't do that
[06:54:29] <MrSun_> but how is then ever a pendant gonna work ?
[06:54:34] <MrSun_> =)
[06:54:46] <MrSun_> i dont understand ... cause like nothing works on pendant more than the jog wheel :/
[06:54:47] <jthornton> look on the forum for examples
[06:55:02] <MrSun_> not with the linuxcnc xhc-hb04 or the xhc-hb04-V6 from that other person :7
[06:55:17] <jthornton> I have remote start/pause examples on the forum
[06:56:08] <MrSun_> hmm where? =)
[06:56:47] <jthornton> HAL Examples
[07:00:52] <MrSun_> feels like i never will get it to work .. and the =0 button that i realy wanted on the pandats seems to be ***ed up to in all versions of hb04 stuff i can find :/
[07:04:26] <MrSun_> http://pastebin.com/yq67s9aw <-- that is directly from the xhc-hb04.tcl file in the linuxcnc git tree
[07:04:42] <MrSun_> thats how they handle start-pause .. shouldnt that work? :/
[07:05:09] <MrSun_> or can it have to be with outdated linuxcnc version on the computer ? (something has been changed in actual linuxcnc to be able to use the pendant stuff? )
[07:12:58] <jthornton> that doesn't look like it would work to me but I don't have a clue what hb04 is
[07:13:44] <MrSun_> and it uses some helper .comp file also to store values etc
[07:13:53] <MrSun_> jthornton, jogging pendant .. xhc-hb04
[07:14:13] <MrSun_> one would think it would work as its merged into the linuxcnc git repository
[08:19:27] <Loetmichel> soo, cnc remote control done... very quiet in the office. (careful, second part is LOUD) -> https://www.youtube.com/watch?v=9u_ChO1AKYY
[10:17:02] <CaptHindsight> Loetmichel: are you using VLC to view the tool with a camera?
[10:21:03] <jmasseo> what is the lowest latency video codec anyway?
[10:21:57] <FrankZappa> !? lowest latency? no codec
[10:22:59] <FrankZappa> http://www.hhi.fraunhofer.de/fields-of-competence/image-processing/solutions/hardware-solutions/ultra-low-latency-video-codec.html
[10:23:13] <humble_sea_bass> the codec that Steam uses to stream games to your tablets etc is the fastest
[10:23:34] <humble_sea_bass> some VNC clients use it too, but I can't look it up right now so good luck
[10:24:13] <FrankZappa> <3 ms is pretty low.

[10:46:15] <FrankZappa> nice
[10:46:46] <FrankZappa> do you do microscopic work?
[10:46:50] <_methods> nah
[10:47:04] <_methods> just looks pretty damn cool
[11:08:55] <SpeedEvil> #homecmos
[11:50:52] <Loetmichel> CaptHindsight: on both ends, yes
[11:51:21] <Loetmichel> encoding on the LinuxCNC machine and decoding at the windows machine in the office
[11:51:31] <CaptHindsight> we were just talking about the camunits for AXIS
[12:00:28] <jthornton> MrSun_, looks like dgarr fixed your hb pendant thing in 2.6
[12:06:16] <Loetmichel> FrankZappa: NO codec is bad
[12:07:22] <FrankZappa> not if your pipe is fat enough :)
[12:07:33] <Loetmichel> tha will produce about 15MB/sec on the lan. a bit much.
[12:07:44] <Jymmm> I can think of a couple of evil codecs
[12:07:52] <Loetmichel> for a 100MBit network ;-)
[12:10:48] <IchGuckLive> hi aöll B)
[12:11:52] <FrankZappa> LAN? yeesh
[12:12:06] <FrankZappa> you really need end-to-end solution for zero latency video
[12:12:15] <Loetmichel> FrankZappa: how do you think i got the video to my office?
[12:12:27] <Loetmichel> [15:01] <Loetmichel> soo, cnc remote control done... very quiet in the office. (careful, second part is LOUD) -> https://www.youtube.com/watch?v=9u_ChO1AKYY
[12:13:13] <FrankZappa> cool!
[12:13:36] <FrankZappa> why not use HDMI?
[12:13:48] <Loetmichel> you can see tha lag between the vnc desktoo and the cideo
[12:13:50] <Loetmichel> video
[12:14:05] <Loetmichel> because the office and the machein are a few more meters apart?
[12:14:23] <Loetmichel> and video cant remote control the machine ?
[12:14:48] <FrankZappa> I would have decoupled those myself
[12:15:41] <FrankZappa> but yeah video over LAN with no ASIC or FPGA solution is going to be lagged
[12:16:40] <Loetmichel> good enough to see a broken bit
[12:16:51] <Loetmichel> or a flying wirkpiece
[12:16:54] <Loetmichel> work
[12:17:03] <CaptHindsight> Camera ----> Lan ----> GbitEthernet Card, no switch and not shared
[12:17:31] <IchGuckLive> Loetmichel: did you got a eye on the XHC-HB04
[12:17:38] <Loetmichel> ?
[12:17:59] <IchGuckLive> wifi linuxcnc
[12:18:18] <Loetmichel> so?
[12:18:38] <IchGuckLive> remote control redy for action on plug
[12:19:02] <MrSun_> jthornton, yeah he did a commit on one of the issues and ive tested it and works like a sharm =)
[12:19:04] <FrankZappa> Loetmichel did you mount the camera to the tool arm? or is your table actually moving the work?
[12:19:42] <Loetmichel> FrankZappa: look at the second part of the cideo
[12:19:44] <Loetmichel> video
[12:19:55] <FrankZappa> ah yes I see it now
[12:19:59] <FrankZappa> clearly it's on the tool arm
[12:20:09] <FrankZappa> I didn't realize the scale until I saw the end.
[12:20:14] <FrankZappa> good job
[12:20:20] <Loetmichel> tha black cylinder with a black cable atached protunding from the vacuum bokc on the sondle is the cam
[12:20:23] <Loetmichel> spindle
[12:22:04] <Loetmichel> yeah, the cam has 10mm diameter
[12:22:20] <Loetmichel> and is waterproof with a glass plate in front of the optics
[12:22:31] <IchGuckLive> Loetmichel: one of the Frankfurt police cam
[12:22:51] <Loetmichel> no
[12:23:10] <Loetmichel> http://www.ebay.de/itm/400597370811 this one
[12:24:12] <Loetmichel> the ones delivered to me have a glass plate instead of the plastic cap on the optics, though
[12:27:04] <CaptHindsight> Loetmichel: is there any manual focus?
[12:27:06] <SpeedEvil> Why do you need low latency?
[12:27:26] <IchGuckLive> SpeedEvil: to get fast speed
[12:27:33] <SpeedEvil> http://www.ebay.co.uk/itm/Andonstar-2MP-USB-Digital-Microscope-Camera-Endoscope-Loupe-Magnifier-Webcam-UK-/171190008984?pt=UK_BOI_Medical_Lab_Equipment_Lab_Equipment_ET&hash=item27dbb83c98 - I got - which is nice.
[12:27:55] <IchGuckLive> SpeedEvil: on steppers below 100k
[12:27:56] <SpeedEvil> Isn't this just for visual inspection - or are you thinking to do feedback over it
[12:28:02] <IchGuckLive> on servo below 10k
[12:28:08] <SpeedEvil> 10k?
[12:28:18] <IchGuckLive> latency
[12:29:10] <IchGuckLive> SpeedEvil: somew mashines of uas are not in retch so you position touch off with the cam

[12:31:53] <tjtr33> i'm repairing a brushed dc drive, has dbl hbridge with 8 pc IRFP250.
[12:31:54] <tjtr33> single sheet insulator ripped off heatsink. what material to use for replacement?
[12:31:58] <CaptHindsight> camera/vision based measurement also seems popular
[12:32:06] <SpeedEvil> tjtr33: you can get sheet insulator
[12:32:25] <tjtr33> yes what material, several listed from copper to kapton
[12:32:26] <SpeedEvil> tjtr33: either mica - which is a transparent somewhat fragile rigid, or silicone based ones
[12:32:38] <SpeedEvil> tjtr33: what did the original one look like
[12:32:50] <CaptHindsight> tjtr33: electrically insulating or not?
[12:32:51] <tjtr33> grey floppy rubber < .101 thx
[12:33:15] <CaptHindsight> ah you can buy those in pads or sheets
[12:33:16] <tjtr33> < .010 ;)
[12:33:20] <SpeedEvil> http://uk.farnell.com/bergquist/spa1500-0-010-00-4-4/sil-pad-a1500-010-4-x4-sheet/dp/8783667
[12:33:45] <tjtr33> thx, usa tho, wondering what the material is called at digikey
[12:33:59] <CaptHindsight> berquist silpad
[12:34:08] <SpeedEvil> Wait - that's conductive?
[12:34:09] <tjtr33> hokay silpad is it thx
[12:34:18] <tjtr33> not conductive i hope
[12:34:27] <CaptHindsight> http://www.bergquistcompany.com/thermal_materials/sil-pad.htm
[12:34:32] <tjtr33> well thermally conductive, elet insulative
[12:34:42] <CaptHindsight> they have either
[12:34:43] <SpeedEvil> Ah
[12:34:51] <SpeedEvil> Farnell seem to have typoed.
[12:35:00] <SpeedEvil> '10 ohms' vs 10^11 ohms
[12:35:17] <CaptHindsight> same thing :)
[12:35:32] <tjtr33> i got XZ&C running on my cnc edm :)
[12:35:37] <CaptHindsight> Danger 1,000,000 OHMS!
[12:35:51] <tjtr33> danger high resistance!
[12:36:26] <CaptHindsight> we had that sign on a door
[12:36:34] <CaptHindsight> to keep people out
[12:37:37] <tjtr33> i hope i can append the digikey order, forgot the dang insulators
[12:37:53] <CaptHindsight> I have before it ships
[12:38:07] <tjtr33> cool thx
[12:38:13] <CaptHindsight> Enco ships seconds after you order
[12:38:57] <CaptHindsight> even by truck it shows up the next a.m.
[12:39:30] <ReadError> too bad enco's site blows
[12:39:39] <ReadError> otherwise I would actually shop there
[12:40:02] <FrankZappa> Loetmichel from what I've skimmed, it seems MJPEG is the lower-latency codec without hardware solutions
[12:40:31] <CaptHindsight> tjtr33: http://www.digikey.com/product-search/en?lang=en&KeyWords=Graphite%20Sheets
[12:40:36] <CaptHindsight> as another option
[12:42:57] <tjtr33> thx, but i dont understand graphite as an electrical insulator ( i make electrode outta that) nor as a thermal transmitter ( same reason )
[12:43:15] <CaptHindsight> depends on the blend
[12:43:40] <CaptHindsight> they use oriented graphite in a polymer
[12:43:47] <tjtr33> isotropic
[12:44:19] <CaptHindsight> gesundheit
[12:44:26] <tjtr33> but i gonna cop out and use the silpad ( cuz i can bake on it too :)
[12:45:10] <SpeedEvil> Graphite is not an inductor
[12:45:11] <CaptHindsight> it's actually non-isotropic
[12:45:12] <SpeedEvil> err
[12:45:15] <SpeedEvil> insulator
[12:45:18] * SpeedEvil is not awake
[12:45:49] <SpeedEvil> It's overwhelmingly likely that if there are 8 transistors on a heatsink, with a thermal pad - that that thermal pad is there as an insulaotr
[12:46:03] <SpeedEvil> And putting a graphite pad on there will make it explode.
[12:46:09] <CaptHindsight> they aren't solid graphite, but when they also say graphite it depends on the particles, they may be coated so they are not good conductors
[12:46:49] <CaptHindsight> big particles with small electrically insulating gaps between them still make for good thermal conductors
[12:47:17] <CaptHindsight> that's the fun of making composites
[12:47:23] <SpeedEvil> Sure.
[12:47:33] * SpeedEvil keeps meaning to make some nice AlC composite
[12:47:42] <CaptHindsight> how to blend things together to get the qualities you want
[12:49:24] <tjtr33> found a roll of old school TO-3's sticky back rubbery insulators, several meters, useless for this tho, the leg holes might conduct
[12:49:58] <CaptHindsight> fill them with silicone
[12:50:38] <CaptHindsight> how thick are they?
[12:50:58] <tjtr33> ~.010
[12:51:27] <tjtr33> yeah silicone goop would work and keep the pcs in place during assy
[12:51:49] <CaptHindsight> what i would do and then just check the temp under load
[12:51:49] <tjtr33> ok, free & on hand wins
[12:52:04] <CaptHindsight> how big is the heatsink that they mount to?
[12:52:22] <tjtr33> 2"x1"x8"
[12:52:32] <tjtr33> 1"fins
[12:54:53] <CaptHindsight> I'd only be concerned where the thermal margin is minimal like a cpu and cheap heatsink fan
[13:00:24] <tjtr33> http://imagebin.org/309395 http://imagebin.org/309394 http://imagebin.org/309393
[13:01:12] <zeeshan> nice vise
[13:01:12] <zeeshan> !
[13:01:18] <zeeshan> looks like a wilton
[13:01:22] <zeeshan> or york
[13:01:24] <tjtr33> in edm the drive basically hold position, i've never felt heat in a drive
[13:01:32] <CaptHindsight> did they all tear?
[13:01:51] <CaptHindsight> the insulators for each or was it one big pad?
[13:02:22] <tjtr33> just the one, the one that covers 11 devices ( 8 fets, 3 vregs)
[13:03:22] <tjtr33> zeeshan, dunno but has great copper wrap around jaw protrects from Palatine Il
[13:03:31] <zeeshan> :]
[13:03:41] <tjtr33> like bra s
[13:03:47] <tjtr33> like a bra
[13:05:43] <CaptHindsight> they did a nice job of fitting as much heatsink into the area as they could
[13:05:52] <tjtr33> gonna remove the C from the cfg , move C drv into Y , then debug further with XYZ machine ( no c for now )
[13:06:14] <CaptHindsight> thats about the ideal fin spacing for natural convection
[13:07:06] <tjtr33> machine is by CHMER ( CHing HUng Machine and Elec Research) not Khmer Rouge as its detractors claimed
[13:07:54] <CaptHindsight> heh
[13:11:08] <tjtr33> thx bbl
[13:21:43] <IchGuckLive> im off BYE
[14:21:04] <obix1> hello, could someone here direct me to a source of information on repairing my vertical mill ways?
[14:22:41] <jdh> www.google.com ?
[14:23:02] <obix1> lol. umm thx, been there for the past few daze
[14:23:09] <jdh> guess that was too easy.
[14:23:17] <jdh> what is wrong with your ways
[14:23:41] <obix1> my Y-axis is hourglass shaped and I need to straighten it out
[14:23:50] <obix1> it binds at the extreems
[14:24:02] <obix1> and is loose in the middle
[14:24:13] <jdh> just worn in the middle?
[14:24:20] <obix1> I believe so
[14:24:36] <_methods> what kind of mill?
[14:24:51] <obix1> it's just a small Sieg X2
[14:24:54] <jdh> scrape the non-worn parts down to match the worn?
[14:25:16] <jdh> I would think those would die before wearing too much
[14:25:30] <_methods> probably came that way
[14:25:33] <obix1> i've worked it with seating compond which helped but didn't solve
[14:26:03] <obix1> I've got a lot of hours on it,
[14:26:18] <_methods> time to scrape
[14:26:21] <_methods> or remachine
[14:26:24] <jdh> are you sure it is the ways that are bad?
[14:26:28] <obix1> my steppers are 24v/ 305's which may be a little weak
[14:26:43] <obix1> but should still run it without play
[14:26:45] <_methods> you sure your gibs are right
[14:26:57] <obix1> how do you me 'right'?
[14:27:00] <jdh> have you replaced the stock crappy wyas?
[14:27:03] <archivist> obix1, I recommend a book called Machine tool reconditioning and applications of hand scraping Edward F. Connelly Machine Tool Publications, try to find a second hand copy
[14:27:19] <_methods> hehe yeah scraping......fun
[14:27:26] <archivist> :)
[14:27:27] <jdh> you could probably buy a new x2 base cheaper
[14:27:32] <obix1> thank you archivist!
[14:27:49] <archivist> and a bit of filing for badly worn cases
[14:28:02] <obix1> I think the bad area is the underside of the dovetail
[14:28:04] <archivist> or take to a grinding company
[14:28:34] <obix1> so scrape, file or grind ?
[14:28:41] <_methods> man that bed is so small if you're patient and attentive you can stone or scrape it pretty easy
[14:29:11] <obix1> ok thx, what would be a good stone to use
[14:29:35] <archivist> obix1, all of those methods, can be used in combination too
[14:29:54] <jdh> what mfg label is on teh mill?
[14:30:01] <obix1> should I try measureing it as I go, or just check for fit
[14:30:08] <obix1> it's a Harbor Freight
[14:30:11] <archivist> measure as well
[14:30:29] <obix1> with micrometer and steel dowels?
[14:30:49] <archivist> you can easily make the machine out of square if you dont measure properly
[14:31:42] <obix1> I've so far only found 1 youtube video addressing the issue, and so far nothing on google but it MUST be there...
[14:31:46] <jdh> http://littlemachineshop.com/products/product_view.php?ProductID=1421&category=
[14:31:51] <jdh> buy one of thsoe
[14:32:00] <obix1> ok thx jdh!
[14:32:10] <jdh> or see if grizzly has one cheaper
[14:32:11] <obix1> I like his site a lot too.
[14:32:26] <_methods> it's a dying art
[14:33:00] <_methods> along with dying artists lol
[14:33:06] <obix1> sweet, I think i'll break the mill down tomorrow and give it a try
[14:33:30] <_methods> http://www.ebay.com/itm/Vintage-Sharpening-Honing-Stone-Very-Large-2-Sided-12-by-2-7-8-by-1-3-8-/181375569281
[14:33:34] <obix1> any idea of what an acceptable tollerence would be?
[14:33:46] <_methods> i have a big stone like that
[14:34:15] <Deejay> re
[14:34:19] <obix1> nice, i'd need a shaped stone for the dovetail though right?
[14:35:34] <_methods> yeah or thin stone
[14:36:04] <archivist> the book with specs is Testing machine tools 8th edition for the use of machine tool makers, users, inspectors and plant engineers G Schlesinger Pergamon Press
[14:36:11] <_methods> how far out are your ways?
[14:36:47] <obix1> i'm guessing in the neighborhood of 10 thousandths
[14:37:31] <_methods> jesus
[14:38:05] <obix1> i can't say for sure as I haven't mic'd them yet...
[14:38:08] <archivist> we are hearing some horror stories in here with some of the machines
[14:38:21] <witnit> its sad ;(
[14:38:30] <witnit> so much wasted time on such machines
[14:38:59] <obix1> lol, i'd love a Bridgeport, someday when I have the cash...
[14:39:25] <_methods> well if you have room for a bridgeport you'd have been better off getting that
[14:39:26] <witnit> from what I heard you basicly have to rework the machines since they are bad when they come out of the crate
[14:39:36] <witnit> bridgport is cheap to come by
[14:39:44] <_methods> bridgeport is not much more than an x2
[14:39:49] <obix1> i have a stone for doing wood files, would it work
[14:40:20] <obix1> a regular sharpening stone, looks like the eBay one
[14:40:39] <witnit> you could probably do it with a belt sander and get closer than china had it (not seiours, dont do this) :P
[14:40:44] <_methods> that's up to you, if you know you can take surface off evenly
[14:40:44] <witnit> serious*
[14:41:12] <obix1> a belt sander eh, sounds faster
[14:41:15] <obix1> :D
[14:41:16] <witnit> hahaha nooooooo
[14:41:18] <witnit> jokes hokes
[14:41:20] <witnit> jokes*
[14:41:28] <_methods> there should be nothing fast about what you are about to do
[14:41:44] <_methods> scraping and straightening ways is time consuming
[14:41:58] <witnit> yep
[14:42:03] <_methods> unless you have years of experience
[14:42:20] <obix1> I think i'll start with the best messurements I can get then ink it and scrap... many times
[14:42:55] <archivist> check you are not producing a well fitting curve
[14:43:08] <obix1> i worked on scraping a Gingery lathe a while back, I'm assuming it will be similar
[14:43:21] <witnit> which model do you have obix1
[14:43:28] <obix1> Sieg X2
[14:43:54] <obix1> I've outgrown it, so I want to get it working smoothly before selling
[14:44:05] <witnit> good of you
[14:44:29] <obix1> probably next step will be G0704
[14:44:38] <obix1> or similar
[14:45:09] <obix1> hossmachine makes them look pretty cool
[14:45:39] <archivist> hoss makes anything else look ok :)
[14:46:03] <witnit> I would suggest that you consider stepping up to industrial grade components whenever possible.
[14:47:08] <witnit> If you are willing to shop around you can spend less and in the long run you will spend more time creating and less time repairing
[14:48:11] <obix1> true, i haven't found much surplus in Montana where I live
[14:48:31] <witnit> understandable
[14:49:26] <obix1> is it possible to get a decent bridgeport for $2000-2500 ?
[14:49:32] <witnit> yes
[14:49:39] <witnit> you can get a very good machine for that cost
[14:49:56] <obix1> what model would you recommend?
[14:50:12] <witnit> what do you plan to do with it?
[14:50:16] <witnit> cnc, or manual
[14:50:21] <obix1> cnc
[14:50:38] <obix1> I mechine a lot of my aluminum castings
[14:52:05] <witnit> just make sure you get one that has a variable speed motor control and always keep your eye out for a pneumatic collet quick change unit.
[14:52:15] <witnit> rpm control*
[14:52:32] <obix1> ok thx good info
[14:52:42] <obix1> tool changer would be awesome!
[14:52:42] <witnit> unless you intend to put a servo on the spindle
[14:52:58] <witnit> well its not a tool changer just a quick pneumatic collet loosener
[14:52:58] <obix1> well bigger is better..
[14:53:13] <obix1> thx for the help and advise, it's very much appreciated, I'll be back later, gotta get kids to dentist
[14:53:29] <witnit> :) wishes for no cavitys good luck1
[14:53:30] <witnit> !
[14:53:38] <obix1> thx laters
[14:57:24] <Jymmm> fuck me, and cheerios too http://www.abc27.com/story/25433201/smartie-snorting-caught-in-york-county-school
[15:03:50] <tjb1> Jymmm: Let me guess, they are going to blame the show Breaking Bad for being a bad influence on children
[15:04:07] <_methods> awesome
[15:04:19] <_methods> i knew there had to be a better way to get smarties into my system
[15:04:29] <tjb1> Didn't take long "I am NOT supporting these kids BUT, they see this in movies on TV and maybe even family members. "
[15:04:39] <tjb1> How about you be a fucking responsible parent instead of blaming TV
[15:05:08] <Jymmm> I blame the parents for not whooping thee shit of of the kids for such dumbassness
[15:06:53] <tjb1> Jymmm: Did you ever fix your gas tank?
[15:06:55] <_methods> ahh those were the days.......bangin out mountains of smartie dust
[15:07:27] <Jymmm> WHACK Why WHACK do WHACK you WHACK act WHACK so WHACK stupid WHACK WHACK WHACK
[15:08:55] <_methods> someone's gotta make the burgers
[15:11:48] <tjb1> Jymmm: do you need help with fuel tank
[15:12:12] <Jymmm> tjb1: No, changed long ago
[15:12:24] <tjb1> :)
[15:46:37] <Swapper_> Hi, anyone cant help me with a error message i get? http://pastebin.com/yhMXikGK i get the error "k word missing with g33" and the spindle dont stop spinning.
[15:47:06] <Swapper_> im using the HSMWORKS emc post to generate the code
[15:47:57] <_methods> g33?
[15:48:05] <Swapper_> yea rigid tapping
[15:48:10] <_methods> ah
[15:48:22] <_methods> are you missing a flag
[15:48:33] <Swapper_> http://www.linuxcnc.org/docs/2.4/html/gcode_main.html#sec:G33.1-Rigid-Tapping
[15:48:41] <_methods> sounds like you need a # for k
[15:49:03] <Swapper_> i have? its 1
[15:49:04] <Swapper_> G33.1 Z-0.750 K0.05
[15:49:09] <Swapper_> for an exampel
[15:49:11] <Swapper_> example
[15:49:25] <Swapper_> and mine is G33.1 Z-11. K1.
[15:49:50] <Swapper_> the example is in inches i guess mine in mm
[15:49:51] <witnit> _methods 4200 parts, and had to regrind
[15:49:58] <_methods> wow nice
[15:50:10] <witnit> im impressed :)
[15:50:28] <witnit> swapper is it possible for one axis to be in IN and the other MM?
[15:50:44] <Swapper_> no ?
[15:50:49] <witnit> haha
[15:51:03] <_methods> is it exceeding your machine velocity?
[15:51:09] <_methods> at your spindle speed
[15:51:41] <Swapper_> dont think so becuse when i tried it before with only the g33.1 and ran silly speeds it faulted.
[15:51:42] <witnit> have you tried other examples with any success?
[15:51:45] <micges> Swapper_: what linuxcnc version?
[15:51:49] <Swapper_> but i can try with a real slow
[15:51:58] <Swapper_> micges: latest version via apt-get
[15:52:04] <Swapper_> updated it 10 min a go
[15:52:43] <cradek> Swapper_: if it doesn't give you the expected pitch, your spindle encoder's scaling is wrong
[15:53:24] <Swapper_> the problem is that it posts a big fat red error message saying "k word missing with g33"
[15:53:34] <Swapper_> and then the spindle keeps rotating
[15:53:55] <cradek> well if you're tapping you should be using g33.1
[15:54:22] <Swapper_> the error message says k word missing with g33/g33.1 so its generic
[15:54:23] <Swapper_> sorry
[15:54:23] <cradek> that error message means just what it says - you're calling g33 without a k word, which is an error
[15:54:32] <Swapper_> but im not!
[15:54:40] <Swapper_> http://pastebin.com/yhMXikGK < k=1
[15:55:00] <Swapper_> i have tried removing the . (dots)
[15:55:02] <Swapper_> no change
[15:55:13] <Swapper_> does it have to have a ending 0 ?
[15:55:29] <Swapper_> like G33.1 Z-11. K1.0
[15:56:31] <cradek> you're looking at the wrong line
[15:56:42] <cradek> the error is N85 Z5.
[15:57:38] <cradek> it probably meant N85 G0 Z5.
[15:57:43] <Swapper_> hum guess thats not a valid one :)
[15:57:54] <witnit> ha still stuck in other g mode
[15:57:58] <witnit> good eye cradek :)
[15:58:56] <Swapper_> ill try !
[15:58:57] <Swapper_> ty
[15:59:38] <cradek> yay, welcome
[16:01:50] <Swapper_> works perfectly !
[16:01:57] <Swapper_> typ vm
[16:02:04] <Swapper_> thanks
[16:02:28] <Swapper_> but that means that the post in HSMWORKS is broken
[16:02:35] <cradek> sure
[16:02:40] <cradek> posts are always broken when you get them :-)
[16:03:07] <Deejay> gn8
[16:07:31] <tjtr33> lawn mow, fence paint, post fix ( programming in forth by leo brodie )
[16:17:05] <gene78> hello guys, inch vs mm problem
[16:18:20] <gene78> about 2 years back, i did some mteric threads with g76, by specifying all metric includeing diamter and length units in the code header
[16:21:01] <gene78> worked just fine. but now i do the same thing in the latest 2.5.4, and every move is wonky. i bent the screw, as it crawled overr the top of the tool, pushed the tailstock back about 1/4 inch out of the center drill, and broke two corners off a $30+ carbide chip.
[16:21:52] <gene78> so, i guess i have to rewrite the ini file in all mm measurements. but the 64 dollar question is why?
[16:22:41] <JT-Shop> you might have mixed up the units in the preamble or something like that
[16:23:57] <gene78> g7g21 - to start, axis gains need to be multiplied by what to go from inches to mm?
[16:25:36] <JT-Shop> that doesn't make any sense, you can freely switch between metric and imperial threads
[16:26:41] <JT-Shop> I cut both metric and inch threads from the same ngcgui subroutine
[16:26:44] <JT-Shop> bbl\
[16:27:29] <gene78> but in the manual i don't find a gmode to switch the x measurements
[16:27:45] <gene78> from inch to mm, bummer
[16:28:13] <gene78> g20-g21 only effect thew z motion it says.
[16:30:53] <gene78> but even that is screwed up, the first move is to drive_line diamter, looks good, next move z to thread start at 46mm, which runs it to 18 displayed in metric?
[16:33:29] <micges> gene78: show some gcode
[16:38:41] <gene78> i don't see a copy paste in konversation?
[16:39:13] <micges> use pastebin.com
[16:41:46] <gene78> do i have to create an account?
[16:43:11] <gene78> it isn't letting me search for the file to submit
[16:45:14] <tjtr33> open in your editor, ^A, ^C, then in pastebin 'paste here' frame, ^V
[16:45:29] <gene78> trying to sign up, it doesn't like my username WTF?
[16:46:02] <tjtr33> i never signed up, i use it w/o
[16:46:06] <CaptHindsight> http://www.pastebin.ca/ no sign up required
[16:46:41] <gene78> Good, pastebin.com always was a PITA
[16:46:45] <tjtr33> http://pastebin.com/m2jRe6Y4
[16:49:25] <gene78> looks like it sent, but no index returned
[16:51:07] <CaptHindsight> who makes the cheapest microcontroller board with >24 IO's? The duinos are all pricey for practically no power or IO's

[16:55:23] <gene78> Is my FF-20 busted?
[16:55:33] <tjtr33> ff20 here too
[16:55:43] <gene78> code is not on this machine
[16:56:31] <gene78> i don't recall that i have ever been able to use the com version
[16:57:32] <gene78> I can access it by an email insert, so I'll go to the house & send it to the list, however broken it may be.
[17:00:11] <PCW> http://www.st.com/web/en/catalog/tools/FM116/SC959/SS1532/PF254044

[17:06:19] <witnit> pastebin with less ads? https://gist.github.com/
[17:07:52] <CaptHindsight> PCW: ever use the open source dev tools with them?
[17:13:46] <cpresser> CaptHindsight: there is a nice gnu toolchain for those. use libopencm3 :)
[17:16:16] <CaptHindsight> ah UWE's old project
[17:16:32] <CaptHindsight> was libopenstm32
[17:17:03] <CaptHindsight> uwe_: ^^
[17:32:03] <PCW> looking at em:blocks or just bare compiler Not using STM chips yet but will use in new designs
[17:38:17] <uwe_> yup, it's called libopencm3 now. I haven't been active in its development for some time now, mostly busy with sigrok these days
[19:23:19] <jdh> what could you get for it
[19:26:24] <jdh> noe.
[19:26:30] <jdh> <wrong damned channel>

[20:10:37] <XXCoder> so close. if semi driver was slightly less reactive...
[20:11:40] <PetefromTn_> Hey R2
[20:19:17] <zmi> hello I can burn it linuxcnc but when I go to reboot I just can see two option install ubuntu or view life ubuntu when I choose it doesnt work, what can i do now???
[20:33:03] <zmi> hello I can burn it linuxcnc but when I go to reboot I just can see two option install ubuntu or view life ubuntu when I choose it doesnt work, what can i do now???
[20:37:45] <cradek> how much ram do you have?
[20:38:59] <CaptHindsight> zmi: did you try any of the suggestions from yesterday?
[20:40:33] <zmi> really i cant do it but today i have a dvd but nothing i have 2 gb
[20:40:51] <CaptHindsight> zmi: what option have you chosen?
[20:41:07] <Valen> when you say "doesnt work"
[20:41:12] <Valen> what actually happens?
[20:42:47] <CaptHindsight> yesterday he said he would put the burned dvd in the drive and then nothing would happen, but other dvd's would load
[20:42:55] <zmi> when reboot i can see on the screen two options, install ubuntu or live dvd without install but when I put one no working
[20:43:26] <Valen> it flashes a big sign saying "no working"?
[20:43:45] <CaptHindsight> now he dest as far as the option screen but we don't know what option he chose or what actually happens
[20:43:58] <CaptHindsight> dest/gets
[20:44:04] <cradek> please explain what you see
[20:44:17] <Valen> I'm betting he probably just isn't waiting long enough, booting off a cd can take quite a while
[20:44:18] <zmi> one moment im going to use translator
[20:44:28] <Valen> or its a dodgy reader
[20:44:32] <Valen> (or writer)
[20:44:35] <cradek> maybe even take a picture of what you see, and share the picture
[20:45:43] <CaptHindsight> if this is legit
[20:47:53] <zmi> I could burn the iso image, reboot when you start with on the screen I see two options, install ubuntu or try ubuntu, I choose to try, but it does nothing, try the option not to install and nothing happens.
[20:48:48] <CaptHindsight> zmi: how long do you wait after choosing? it can take several minutes
[20:49:25] <zmi> i have wait about five or six minutes
[20:49:29] <XXCoder> expecially if cd drive is slow
[20:49:41] <Valen> what is the drive doing?
[20:50:18] <CaptHindsight> what motherboard? it might be bios issues or need kernel settings changed
[20:50:22] <zmi> cd drive stops, no sound
[20:50:58] <Valen> ok, I'm going from memory here but when you have the options down the bottom there is a menu and its something like press F6 to edit the kernel command line?
[20:51:11] <Valen> I can't remember which key it is
[20:51:27] <Valen> anyway pick, try ubuntu, then press that key
[20:51:36] <zmi> I have not changed anything
[20:51:59] <Valen> then go to the end of the line with the arrow keys, then delete the bit where it says quiet splash
[20:52:07] <Valen> only delete those words
[20:52:11] <Valen> then press enter
[20:53:30] <Valen> you should get pages of stuff scrolling past
[20:54:04] <Valen> if there is too much junk it might hide the error message, in that case try just taking the splash part off instead
[20:56:02] <zmi> i think i cant do it that
[20:57:43] <Valen> http://askubuntu.com/questions/152847/how-to-access-boot-options-12-04-live-usb
[20:57:57] <Valen> press escape to get out of that menu
[20:58:10] <Valen> it is F6, "other options"
[20:59:58] <zmi> i must delete quiet splash?
[21:00:50] <PetefromTn_> Well I did it...
[21:01:09] <PetefromTn_> I just took the plunge and ordered a BRAND NEW KURT VISE!!! YEAY!! LOL
[21:01:14] <jdh> woohoo!
[21:01:40] <PetefromTn_> I figure the pocket book will hurt for a bit but the nice vise will serve me well for years...
[21:02:02] <jdh> I thought the same about my cheapass shars
[21:02:04] <PetefromTn_> Using them at work all the time I have come to realize they are expensive for a good reason.
[21:02:11] <XXCoder> nice
[21:02:26] <PetefromTn_> I have a cheapass shars and it is giving me problems.
[21:02:37] <jdh> yours probably gets more use than mine.
[21:02:46] <XXCoder> I got bit of good news from training work too. :D They have big bin of scrap wood and said I could grab whatever
[21:02:48] <PetefromTn_> It is not very flat at all across the 6" width and the
[21:02:49] <jdh> the pin fell out of my hanlde
[21:03:05] <XXCoder> cnc wood aloy! too bad no MDF or even lamated wood
[21:03:10] <zmi> valen i must delete quiet splash in that menu?
[21:03:11] <PetefromTn_> little round piece fell out of the movement that helps the angle lock work.
[21:03:19] <jdh> and I accidentally MDI'ed the top of one jaw
[21:03:27] <jdh> decimal points matter!
[21:03:40] <Valen> if you do it will give you a clue as to what is happening yes
[21:03:49] <Valen> try just deleting spash first
[21:04:00] <PetefromTn_> Oh yeah man..
[21:04:07] <PetefromTn_> I have actually done that too.
[21:04:21] <Valen> shars?
[21:04:40] <Valen> you guys work in inches, yeah decimal points really matter
[21:04:42] <PetefromTn_> I got the Kurt 688 vise
[21:04:44] <Valen> and you want a lot of them
[21:04:58] <XXCoder> all of em?
[21:05:02] <XXCoder> ;)
[21:05:06] <PetefromTn_> decimal points matter whether you are in inches or metric.
[21:05:17] <zmi> i will i try thanks
[21:05:32] <PetefromTn_> a LOT of the parts we make at work are metric
[21:05:48] <PetefromTn_> I am getting more and more used to working with metric dimensions.
[21:06:16] <Valen> PetefromTn_: they matter less when you are working in metric ;->
[21:06:24] <Valen> about 25 times less to be precise ;->
[21:06:29] <PetefromTn_> I cannot wait to get my new vise here and be able to rely on the flatness and squarenes..
[21:06:33] <PetefromTn_> 25.4
[21:06:35] <XXCoder> I hope STL would finally replace imperial system. meteric makes more sense
[21:06:42] <Valen> which is *about* 25 ;-P
[21:06:50] <PetefromTn_> hehe
[21:07:28] <PetefromTn_> I need to pickup a nice facemill now and I should be able to do about anything I need to in the machine.
[21:07:45] <zeeshan> nice PetefromTn_
[21:07:57] <zeeshan> which face mill are you going to go with?
[21:08:01] <PetefromTn_> my custom flycutter works great but having used all the different ones at work I can appreciate just how important they are.
[21:08:06] <PetefromTn_> Not really sure yet.
[21:08:16] <zeeshan> flycutter surface finish > face mill
[21:08:18] <PetefromTn_> Whichever one I can get my hands on that kicks ass and does not break the bank.
[21:08:26] <zeeshan> but face mill eats metal like nothing :D
[21:08:33] <PetefromTn_> you can say that again.
[21:08:48] <zeeshan> the only way i've seen a face mill do well is
[21:08:49] <zeeshan> at gates
[21:08:55] <zeeshan> they had literally a department for "tool maintenance"
[21:08:57] <XXCoder> face eat metal lol
[21:09:02] <zeeshan> guy sat there w/ the face mills
[21:09:03] <PetefromTn_> the last two days I have been making a bunch of different 4140 and tool steel parts with a lot of facemilling.
[21:09:12] <XXCoder> also, "face mill" lol
[21:09:15] <zeeshan> and adjusted each insert down to 0.0001" in height of each other
[21:09:33] <PetefromTn_> That is not easy to do really I have found.
[21:09:42] <zeeshan> they had a jig for it
[21:09:57] <PetefromTn_> I was actually surprised at how far out the individual inserts can be.
[21:10:02] <jdh> take out all the inserts but one and you have a flycutter
[21:10:12] <zeeshan> jdh LOL
[21:10:12] <PetefromTn_> altho some of the heads have been crashed pretty good.
[21:10:37] <zeeshan> well the cheaper inserts have a tolerace of what 1 thou?
[21:10:50] <zeeshan> then the good ones are .0005" then the super expensive ones are 0.0001"?
[21:10:51] <PetefromTn_> the seco 2" insert mill I used a lot today is pretty jacked up but still eats copious amounts of metal easily.
[21:10:51] <zeeshan> i forget
[21:10:53] <jdh> I got a chinese 2.5" face mill. It seems to work well enough for me and aluminum
[21:11:24] <zeeshan> i only have the round one by seco
[21:11:32] <PetefromTn_> I never realized just how damn soft aluminum is really... Compared to all the steels we cut there ally is like freakin' butter.
[21:11:34] <zeeshan> the other one is mitsubishi!
[21:11:40] <zeeshan> with funky inserts
[21:12:17] <zeeshan> PetefromTn_: how much are you looking to spend on one?
[21:12:29] <zeeshan> i see them go for dirt cheap locally
[21:12:57] <PetefromTn_> we programmed a part today that had a 2" insert mill with a cut width in a single pass of 32mm wide and .075 deep....
[21:13:12] <zeeshan> isnt that normal?
[21:13:12] <PetefromTn_> in 4140 pre hard.
[21:13:14] <zeeshan> oh
[21:13:18] <PetefromTn_> apparently....LOL
[21:13:33] <PetefromTn_> spindle load was like 70 percent.
[21:13:51] <PetefromTn_> 1000 RPM and I cannot remember the feedrate.
[21:14:04] <zeeshan> hey PetefromTn_
[21:14:06] <PetefromTn_> I can tell you it moved some serious metal all day long.
[21:14:09] <zeeshan> have you been hearing the news about florida?
[21:14:17] <PetefromTn_> I am looking to spend as little as possible of course.
[21:14:21] <PetefromTn_> what news.
[21:14:27] <zeeshan> the flooding going on there
[21:14:58] <PetefromTn_> No where.. I just spoke to my best Friend Frank who lives in Boca raton yesterday afternoon and he said it was pretty nice there.
[21:15:00] <zeeshan> http://www.usatoday.com/story/news/usanow/2014/04/29/tornadoes-south/8446307/
[21:18:04] <PetefromTn_> huh according to that the worst weather is in Alabama and tennessee etc. They did not even mention Florida.
[21:18:12] <zeeshan> first line

[21:18:56] <zeeshan> picture of pensacola, flordia
[21:20:52] <PetefromTn_> Interesting. Looks like North Florida. Florida is not immune from flooding of course especially when you consider the height above sea level.
[21:21:32] <jdh> panhandle. North florida has also been flooding. rivers are just now receding
[21:21:51] <zeeshan> i live 700m above sea level :/
[21:24:17] <ChuangTzu> when i lived in florida, the highest point in the county was the landfill
[21:24:31] <ChuangTzu> highest point in florida is like 100m
[21:24:45] <zeeshan> hehe
[21:24:55] <PetefromTn_> yup...
[21:25:13] <ChuangTzu> florida has the lowest highest point of any state
[21:25:15] <ChuangTzu> :)

[21:32:26] <zeeshan> i read that as 2"

[21:34:16] <zeeshan> the mitsubishi one uses wmng inserts
[21:34:25] <zeeshan> i dunno if its a face mill or supposed to be an end mill
[21:34:27] <zeeshan> i use it as a face mill
[21:34:29] <zeeshan> !
[21:34:51] <PetefromTn_> what size arbor does it take...
[21:35:00] <zeeshan> which one
[21:35:03] <zeeshan> the mitsu?
[21:35:25] <PetefromTn_> Its a shame you have R8 I have a spare 3/4 inch facemill or insert mill arbor but it is cat40..
[21:36:48] <zeeshan> measured it
[21:36:49] <zeeshan> its 1"
[21:37:39] <zeeshan> ive seen a similar seco one go for 60$ locally

[21:38:21] <zeeshan> what the bloody hell is that?!?!
[21:38:40] <PetefromTn_> monster insert mill.
[21:38:48] <zeeshan> looks like a cutter from hell
[21:38:53] <PetefromTn_> we have some similar to that at work/
[21:38:58] <zeeshan> what is it used for
[21:39:27] <PetefromTn_> milling
[21:39:55] <PetefromTn_> heavy milling in deep pockets
[21:40:00] <zeeshan> ahh
[21:40:17] <zeeshan> dude
[21:40:19] <zeeshan> check this pic out

[21:40:38] <zeeshan> that cant be a single pass can it?!
[21:40:54] <zeeshan> yea it can be
[21:40:58] <zeeshan> its a finishing cutter
[21:42:06] <PetefromTn_> dunno.
[21:42:24] <PetefromTn_> not the best finish for a finishing cutter..
[21:42:30] <zeeshan> haha
[21:42:32] <zeeshan> you can see the lines :D
[21:44:55] <PetefromTn_> got an interesting set of projects from a local customer today. gonna start drawing on it this friday and hopefully we can get a prototype machined soon.
[21:45:14] <witnit> do tell
[21:45:57] <PetefromTn_> Well I don't wanna jinx it LOL
[21:46:09] <PetefromTn_> It is for custom sportscars tho...
[21:46:26] <PetefromTn_> particularly RX7's..
[21:46:51] <zeeshan> whatcha makin
[21:47:05] <PetefromTn_> Got a bunch of dimensions and drawings here I gotta turn into a solid model and show the customer.
[21:47:33] <PetefromTn_> Spent two hours over there today discussing it and got some original parts to go off of.
[21:47:48] <PetefromTn_> It is nothing earth shattering but I will show you if I get the job.
[21:47:58] <XXCoder> https://www.youtube.com/watch?v=hFf6FLXDQcU crazy
[21:48:04] <PetefromTn_> Right now it is just an idea they want to explore.
[21:50:25] <PetefromTn_> I have glued op TONS of hardwoods for all sorts of projects when I worked as a custom woodworker.
[21:50:48] <PetefromTn_> We turned some crazy columns and stuff that were solid or hollow and some were quite huge.
[21:52:00] <XXCoder> lol ok
[21:57:30] <humble_sea_bass> I heart woodwork
[21:58:00] <XXCoder> I look forward to cnc routing junk wood :D
[21:58:34] <humble_sea_bass> hard wood
[21:59:07] <humble_sea_bass> soft wood tends to mill like hot garbage
[21:59:36] <XXCoder> light touch lol
[22:02:26] <witnit> I was just carving on some osage orange earlier :)
[22:03:35] <XXCoder> what I does hope for is ability to design something cool and sell em
[22:03:51] <XXCoder> likely something related to my culture and maybe scifi stuff
[22:06:46] <zeeshan> is there any way to score a big ass fraction to decimal to mm chart
[22:06:50] <zeeshan> w/ tap drill sizes etc
[22:06:53] <zeeshan> a BIG one
[22:06:55] <zeeshan> fore free :D
[22:07:15] <zeeshan> it seems like starrett , mitutoyo etc would give it out as advertisment
[22:07:35] <XXCoder> zee do a multiple paper printout
[22:07:43] <XXCoder> "free".
[22:07:43] <zeeshan> lol
[22:07:45] <zeeshan> ghetto
[22:07:46] <PetefromTn_> I got one...
[22:07:49] <zeeshan> i want it laminated
[22:08:18] <XXCoder> heh I could do ghetto lamation at work using sealer but would be really bad looking :P
[22:09:05] <zeeshan> i have yet to find a shop thats going out of business
[22:09:06] <PetefromTn_> I cannot remember where I got it but it is sheet plastic and has all that stuff on it. It is maybe 20x30 inches or so?
[22:09:08] <zeeshan> i figure i could find one there
[22:09:14] <zeeshan> PetefromTn_: whered you score thart
[22:09:22] <PetefromTn_> I am trying to remember.
[22:09:27] <zeeshan> i need to cover my walls!
[22:09:30] <zeeshan> garage looks depressing :P
[22:09:31] <PetefromTn_> I wonder if you can get one from Fastenal...
[22:09:36] <zeeshan> and its even more depressing looking at a tiny a4 chart
[22:09:49] <PetefromTn_> get some sexy babe posters and RX7 posters etc...
[22:10:03] <zeeshan> http://www.fastenal.com/content/documents/2012/LandingPages/Metalworking/9701309_TapDrillPoster_24x36.pdf
[22:10:05] <zeeshan> you're right
[22:10:06] <PetefromTn_> ;)
[22:10:06] <zeeshan> dude
[22:10:10] <zeeshan> fastenal makes a really nice one
[22:10:29] <PetefromTn_> yup there ya go.Probably can order one from them
[22:11:21] <PetefromTn_> mine is basically just like that but it is not from Fastenal.
[22:12:03] <zeeshan> i wonder how much that'd cost to print
[22:12:09] <zeeshan> i bet like 35$ to print and laminate
[22:12:31] <PetefromTn_> damn I hope not.
[22:12:42] <PetefromTn_> You can probably get it on some posterboard and have that laminated.

[22:20:10] <PetefromTn_> Man I am excited to get that Kurt vise... Wanted one for a long time.
[22:20:45] <zeeshan> http://www.starrett.com/documentation
[22:20:49] <zeeshan> apparently they'll ship it to you for free?
[22:20:50] <PetefromTn_> I think I will still try to grind that shars CNC vise at work maybe I can get them to match heights to the new kurt

[22:21:26] <zeeshan> son of a.
[22:21:34] <PetefromTn_> No kiddin.
[22:21:37] <humble_sea_bass> most dealers will give that stuff away
[22:21:39] <PetefromTn_> I need to get on there.
[22:21:43] <PetefromTn_> I was gonna say that.
[22:21:45] <CaptHindsight> but there's no poster babes on them either
[22:21:52] <zeeshan> i dont want poster babes
[22:21:54] <zeeshan> i got a babe at home
[22:21:55] <zeeshan> :D
[22:21:56] <PetefromTn_> That is true especially if you order tooling from them.
[22:21:59] <humble_sea_bass> you do mang
[22:22:06] <humble_sea_bass> http://www.ebay.ca/itm/1980s-Budweiser-Sexy-Babe-Red-White-Bud-Man-Cave-Beer-Poster-28x20-/161270407682?pt=LH_DefaultDomain_0&hash=item258c772202&_uhb=1
[22:22:10] <humble_sea_bass> how could you not
[22:22:27] <zeeshan> wow
[22:22:31] <zeeshan> fastest response ever from that ebay guy
[22:22:39] <zeeshan> he's looking at how much itll cost to ship
[22:23:01] <zeeshan> PetefromTn_: i don't buy tools from my local supplier
[22:23:05] <humble_sea_bass> http://www.ebay.ca/itm/Budwiser-Calander-Pin-Up-Girl-Poster-1987-/290853475301?pt=LH_DefaultDomain_0&hash=item43b837d3e5&_uhb=1
[22:23:05] <zeeshan> they're stupid expensive.
[22:23:09] <zeeshan> its prolly double what usa charges
[22:23:29] <zeeshan> 7/8 4 flute m42 end mill = $60
[22:23:30] <zeeshan> lol
[22:23:59] <PetefromTn_> actually that is not that bad for a big endmill...
[22:24:09] <zeeshan> when you buy 20 of them brand new
[22:24:09] <zeeshan> for $100
[22:24:12] <zeeshan> its really bad :P
[22:24:16] <zeeshan> (name brands too)
[22:24:32] <zeeshan> the main thing i've bought brand new is a drill point gauge
[22:24:38] <PetefromTn_> where can you buy 20 brand new name brand endmills for $100.00
[22:24:43] <zeeshan> kijiji!
[22:25:12] <PetefromTn_> I need to pickup some spot drills
[22:25:13] <CaptHindsight> zeeshan: decided to get one to try http://www.perfdiesel.com/assets/images/products/6.4%20INJECTOR.jpg
[22:25:55] <zeeshan> nice :D
[22:25:57] <zeeshan> looks fancy
[22:26:06] <zeeshan> is that a stainless steel body or aluminum
[22:26:21] <CaptHindsight> http://image.dieselpowermag.com/f/tech/1403_mechanical_heui_and_common_rail_injectors_basic_training/67154584/6-4l-power-stroke-fuel-injector.jpg
[22:26:27] <CaptHindsight> steel
[22:26:40] <CaptHindsight> I just need to make my own tips
[22:27:40] <PetefromTn_> what the hell are you gonna do with that?
[22:27:51] <CaptHindsight> print nozzle
[22:29:26] <SpeedEvil> for what?
[22:29:41] <SpeedEvil> you mean plastic?
[22:29:59] <CaptHindsight> high viscosity fluids, inks, coatings, polymers, resins etc
[22:30:24] <CaptHindsight> cheap since they are made in such high volumes
[22:30:34] <SpeedEvil> It's designed for very, very low viscosity fluids
[22:31:13] <CaptHindsight> I might play with the internal orifice a bit but the nozzles will be custom
[22:31:19] <zeeshan> SpeedEvil: he knows that :P
[22:31:24] <zeeshan> he told me its of milk consistency
[22:31:26] <zeeshan> i think itll work fine
[22:31:32] <CaptHindsight> fuel is around 1cps
[22:31:38] <zeeshan> whats cps
[22:31:44] <SpeedEvil> Centipoise
[22:31:48] <SpeedEvil> viscosity measurement
[22:31:48] <zeeshan> no idea what tha tunit is
[22:32:06] <zeeshan> i just know pascal seconds
[22:32:18] <CaptHindsight> plus at that low viscosity they eject quite a large amount of fluid
[22:32:28] <zeeshan> dynamic viscosity?
[22:32:35] <CaptHindsight> I just need 1%
[22:32:56] <CaptHindsight> viscosity of a newtonian fluid
[22:33:03] <tjtr33> CaptHindsight, do all those injectors require a pressurized source, and merely are valves, or can some pump by themselves?
[22:33:48] <zeeshan> ah
[22:33:59] <zeeshan> 1 Pa*s = 10 poise
[22:34:18] <CaptHindsight> tjtr33: it depends on the design, some are merely valves, the one in the pic requires low pressure ~50psi but the internal pressure might be 20K psi at the nozzle
[22:34:19] <zeeshan> i guess the guy didnt like scientific notiation too much
[22:34:22] <zeeshan> had to invent his own unit
[22:36:41] <CaptHindsight> we use other valves with inlet pressures for the fluids of 1-2k psi
[22:37:55] <CaptHindsight> with a 25um orifice you might only get a micoliter drop by opening the valve for 1mS
[22:40:11] <tjtr33> huh, its not microliter,its micoliter... is that a typo that became a standard:)
[22:41:19] <CaptHindsight> I made the typo :)
[22:41:33] <tjtr33> google sez it has no r
[22:42:04] <tjtr33> oh you made it famous
[22:42:12] <CaptHindsight> uL
[22:42:24] <zeeshan> micrrrrrrrrrrrrrrrrrrrrrro
[22:42:40] <tjtr33> yeah, i cant focus on the 2nd monitor, my bad
[22:43:25] <PetefromTn_> Okay folks good night.
[22:43:29] <zeeshan> cya pete
[22:43:34] <PetefromTn_> cya
[22:44:29] <CaptHindsight> zeeshan: how many gallons of fuel per hour do you think that injector delivers?
[22:45:09] <CaptHindsight> with the stock nozzle
[22:46:10] <zeeshan> well i know the 6.4L in the ford trucks
[22:46:16] <zeeshan> and they make like 350-380 hp
[22:46:38] <zeeshan> 350 hp / 8 = 43.75HP per cyl
[22:46:44] <zeeshan> so 44 lb/hr or so
[22:47:09] <SpeedEvil> That's assuming it's open all the time
[22:47:22] <zeeshan> no
[22:47:28] <zeeshan> theyre rated for 80% duty cycle
[22:47:30] <zeeshan> factory
[22:47:35] <humble_sea_bass> only amateurs take their foot off the gass
[22:47:48] <zeeshan> er
[22:47:51] <zeeshan> they could be at 100%
[22:47:54] <zeeshan> im thinking of gasoline injectors
[22:48:03] <zeeshan> i havent seen the profile curve of a diesel injector
[22:48:12] <zeeshan> i persume it gets finicky after 80%
[22:48:15] <zeeshan> (non linear)
[22:48:29] <zeeshan> btw thats about 460cc/min
[22:48:34] <zeeshan> if youre into metric units
[22:48:51] <zeeshan> when dealing with fluids, i really like metric units :P
[22:49:18] <CaptHindsight> and we're down around 10cc/min
[22:50:27] <CaptHindsight> http://www.boschautoparts.com/BAP_Technical_Resources%2fDiesel%20Parts%2fCommon%20Rail%20Systems%20CRS3.pdf
[22:50:41] <CaptHindsight> 1800-2000 bar
[22:51:37] <zeeshan> what are you passing through it again
[22:51:39] <zeeshan> what matericla
[22:51:41] <zeeshan> material
[22:52:07] <CaptHindsight> mostly monomers and oligomers
[22:52:56] <CaptHindsight> have to possibly change seal materials
[22:53:02] <zeeshan> why
[22:53:42] <CaptHindsight> compatibility issues
[22:53:54] <zeeshan> youve lookedf at the parker handbook?
[22:55:12] <zeeshan> http://www.parker.com/literature/ORD%205700%20Parker_O-Ring_Handbook.pdf
[22:55:13] <zeeshan> page 162
[22:55:42] <zeeshan> pretty sure factor those injectors have butadiene o-rings
[22:55:54] <CaptHindsight> sometimes there are solvents like MEK in the mix
[22:56:02] <zeeshan> whats mek stand for
[22:56:24] <CaptHindsight> http://en.wikipedia.org/wiki/Methyl_ethyl_ketone
[22:56:48] <zeeshan> yea
[22:56:52] <zeeshan> thats '4'
[22:56:55] <zeeshan> unsatisfactory :P
[22:58:03] <zeeshan> looks like fluorocarbon FKM, butyl are the best candidates
[22:58:13] <zeeshan> both are very common
[22:59:02] <CaptHindsight> it all depends, we blend all types of resins
[23:02:39] <CaptHindsight> http://www.youtube.com/watch?v=ftchx1TDNJo Bosch operates a bit differently
[23:04:16] <CaptHindsight> these don't look like higher viscosity fluids would work well since the internal force amplifier amplification might not work fast enough to bother with using them
[23:04:50] <CaptHindsight> neat design though
[23:06:17] <CaptHindsight> http://www.ebay.com/itm/TOOL-6-4L-FORD-DIESEL-POWERSTROKE-INJECTOR-SLEEVE-REMOVAL-INSTALL-KIT-/141259609981 the tool cost more than a new injector
[23:09:11] <CaptHindsight> http://www.nordson.com/en-us/divisions/efd/products/jet-valves/pages/default.aspx sure beats $7-13K for these
[23:17:12] <CaptHindsight> hmm 500cc/min is 30L/hour per nozzle, you could print some big parts pretty fast
[23:24:29] <CaptHindsight> tjtr33: do you ever visit the Design-2-Part Shows? http://www.d2p.com/
[23:25:54] <tjtr33> i got tix but no time, tomorrow isnt it?
[23:26:12] <CaptHindsight> and Thursday
[23:26:29] <tjtr33> you goin?
[23:26:46] <CaptHindsight> usually an open bar on the 1st day at 4:00
[23:26:59] <CaptHindsight> so I tend to walk through after 2
[23:27:23] <tjtr33> :)
