[00:01:44] <andypugh> t12: I want that big chisel
[00:03:52] <andypugh> I made a scratch tool for this, a router-cut groove would have looked wrong. It only took about an hour to make the tool and form the profile: https://plus.google.com/photos/108164504656404380542/albums/5854209973166221953
[00:05:38] <andypugh> (the first 5, the second 4 are something entirely more modern, this in fact: http://benlovejoy.wordpress.com/2013/03/27/idesk/ )
[00:05:39] <Tom_itx> what kind of wood is that?
[00:05:46] <andypugh> Oak
[00:05:56] <andypugh> (in both cases)
[00:06:34] <syyl_> i restored a new vise today ;)

[00:08:58] <syyl_> https://dl.dropbox.com/u/24396704/Reime%20Universalschraubstock/IMG_1758.JPG
[00:09:14] <andypugh> I am never sure if those are going to be stiff enough to be useful. I am sure that for some jobs nothing else will do (short of a Deckel with the universal table)
[00:09:30] <syyl_> i will use it on my tool/cutter grinder
[00:09:38] <syyl_> for turning tools

[00:10:21] <andypugh> syyl_: OK, let me take a photo..

[00:19:47] <syyl_> no permission to open it..
[00:21:47] <andypugh> Hmm, how about: https://plus.google.com/photos/108164504656404380542/albums/5747722155741347649/5860924673167260434
[00:22:12] <syyl_> that works
[00:22:46] <syyl_> your lathe needs some serios cleaning ;)
[00:23:22] <syyl_> that protractor is nice
[00:23:33] <syyl_> but 0 seems to be off ;)
[00:23:54] <Tom_itx> his table is warped
[00:24:50] <andypugh> The protractor is not nice _because_ the zero is off.
[00:24:53] <Tom_itx> that is a nice tool to have though
[00:25:02] <Tom_itx> not adjustable?
[00:25:13] <syyl_> with a surface grinder ;)
[00:25:15] <andypugh> Not enough,
[00:25:21] <syyl_> that would make a nice gift to somebody you dont like
[00:26:07] <andypugh> It would be a really nice tool, if it actually measured angles.
[00:26:39] <syyl_> for my part, i am cured with cheap measuring tools :D
[00:26:51] <andypugh> And maybe it would be accurate if I were to subtract 24' from every measurement.
[00:27:17] <syyl_> i only buy chinese stuff that i can fix ;)
[00:27:53] <syyl_> ah
[00:28:00] <syyl_> one of the knuckles spotted
[00:28:01] <syyl_> http://www.cncecke.de/forum/attachment.php?attachmentid=79614&d=1364600448
[00:28:12] <syyl_> ah sorry
[00:28:13] <syyl_> https://dl.dropbox.com/u/24396704/Reime%20Universalschraubstock/IMG_1768.JPG
[00:28:42] -!- PCW [PCW!~chatzilla@99.88.10.65] has parted #linuxcnc
[00:29:07] <andypugh> I would relieve the centre in a lathe, then scrape the outer 13mm.
[00:29:45] <syyl_> i took the "scrape all of it"-card
[00:29:58] <syyl_> two passes and it got much better
[00:29:59] <syyl_> https://dl.dropbox.com/u/24396704/Reime%20Universalschraubstock/IMG_1769.JPG
[00:30:05] <syyl_> https://dl.dropbox.com/u/24396704/Reime%20Universalschraubstock/IMG_1770.JPG
[00:30:33] <syyl_> at least it stopped to rock on the surface plate
[00:31:03] <syyl_> a bit later it started to look like something
[00:31:04] <syyl_> https://dl.dropbox.com/u/24396704/Reime%20Universalschraubstock/IMG_1772.JPG
[00:32:12] <andypugh> I have a feeling (and no science) that a high-pressure clamping to an outer ring is stiffer than an all-over clamp.
[00:32:14] -!- mourner has quit [Quit: mourner]
[00:32:31] <syyl_> there might be something to that
[00:32:37] <andypugh> I think it is definitely stiffer in torsion.
[00:34:08] <syyl_> i think i will relieve the base in the center
[00:34:21] <syyl_> i can chuck it easier on the face plate
[00:34:39] <andypugh> This looks nicer than my chinese thing, but I am not sure it will measure my angle. http://www.ebay.co.uk/itm/Grey-Rushton-Vernier-Protractor-As-Photo-/160934608730?pt=UK_Measuring_Tools_Levels&hash=item2578733f5a
[00:35:26] <syyl_> it has a nice wooden box at least
[00:35:39] <syyl_> i have one that looks like that one
[00:35:53] <syyl_> with the sliding rule
[00:36:08] <andypugh> I need to measue over a step. Let me see if I can find a picture.
[00:39:11] <andypugh> https://plus.google.com/photos/108164504656404380542/albums/5747722155741347649/5648298987857956962 If you ignore what it was a picture of, the angle is that split line between just under the words "when spiral milling". It is clamped by the nut you can see. The whole X-axis rotates. My measurement is the angle over that step.
[00:40:05] <syyl_> uh
[00:40:07] <syyl_> ok
[00:40:44] <syyl_> cant you setup a dial indicator in a known distance to the swivel point?
[00:40:51] <syyl_> and then calculate the angle
[00:40:54] <andypugh> Now, the Chinese thing does that no problem, as the setsquare part slides.
[00:41:19] <andypugh> And yes, a DTI is probably the proper way to measure.
[00:41:33] <syyl_> or a sine bar + dial indicator
[00:41:40] <syyl_> (magnetic sine bar)
[00:41:54] <andypugh> Ah. No. The whole X axis swivels...
[00:42:05] <syyl_> but Y stays
[00:42:42] <syyl_> http://www.ballbach-messzeuge.de/06/60/Bilder/6040001.jpg
[00:43:00] <syyl_> you can set it up "standing" on the short side
[00:43:12] <syyl_> and run the y-axis back and forward
[00:43:26] <andypugh> Yes, an accurate square on the Y would work, bit then I have to clock the base of the square to get it acurately on X, then swivel X and clock Y
[00:44:37] <andypugh> Which will work, but is effort, and requires a nice square, which I don't currently have.
[00:48:36] <syyl_> hmm
[00:48:48] <syyl_> there seem to be a lot ways to do it
[00:48:54] <syyl_> but my bed calls for me
[00:51:06] -!- syyl_ has quit [Quit: Leaving]
[00:52:45] <t12> anyone know a reasonable source for a 4.5MT to 3MT sleeve?
[00:52:48] <t12> (or 2?)
[00:53:27] <t12> apparently clausing sells one but have to call
[00:53:36] <ds3> what uses a MT4.5?
[00:53:43] <t12> a whole mess of lathes, apparently
[00:54:04] <t12> the story is that 4.5 was made so that some convient size of collet? could easily be fit
[00:54:11] <t12> cause 4 is too small and 5 would be too big
[00:54:24] <ds3> I wonder if that's what those 5C capable lathes are since they have an adapter sleeve
[00:54:30] <t12> yeah
[00:54:44] <t12> (5c is the thing forums mention in ref to this)
[00:54:52] <ds3> Oooh
[00:55:00] <ds3> why not a 5C nose + a 5C to MT adapter?
[00:55:17] <t12> this would be for testbar mount
[00:55:22] <t12> and really, anything morse mount
[00:56:07] <andypugh> t12: CNC lathes turn tapers reallly well.
[00:56:18] <t12> however, i have no cnc lathe
[00:56:33] <andypugh> So, make one.
[00:56:46] <t12> heh
[00:56:49] <t12> making the cnc lathe
[00:56:51] <t12> to make the adapter
[00:56:53] <t12> for the non cnc lathe
[00:57:12] <andypugh> Even my ghastly chinese machine with steppers can make a really good socket-taper pair.
[00:57:33] -!- Santolina has quit [Ping timeout: 245 seconds]
[00:57:33] <andypugh> Much better than I ever managed on a manual lathe.
[00:57:57] <t12> i guess in theory my next alignments should be
[00:58:03] <t12> headstock/tailstock to eachother + bed
[00:58:13] <t12> but thats like 2 testbars and the 4.5 adapter
[01:00:06] <t12> or fix the teeth grind now without those adjustments
[01:00:16] <t12> and just eyeball it off the chuck badly
[01:01:14] <andypugh> t12: Just machine a bar between centres and measure it.
[01:02:35] <andypugh> Ah, no, that's a different test. Still worthwhile (that is how you align a tailstock)
[01:05:03] -!- parallels has quit [Ping timeout: 260 seconds]
[01:05:51] <andypugh> Machining a bar held only in the chuck and measuring the diameter tells you how well the spindle axis is aligned to the bed. A bad chuck affects that, but indirectly. You will get ovality that varies along the test piece. But if the work is round, but tapered, you have a good chuck and a misaligned spindle.
[01:08:44] -!- asdfasd has quit [Ping timeout: 255 seconds]
[01:12:32] <t12> i know right now the chuck is way off
[01:12:36] <t12> due to me messing up previous grinding
[01:12:48] <t12> i'm clamping jaws diffntly (a way archivist suggested)
[01:13:45] <t12> last time they ended up sorta conical
[01:15:08] -!- jfire has quit [Quit: Leaving.]
[01:18:23] <DaViruz> andypugh: flex will affect that a lot for any meaningful length
[01:19:29] <DaViruz> better of just chucking a "good" bar and indicating on it twice, rotating it 180 degrees to compensate for chuck inaccuracy
[01:23:22] -!- zzolo has quit [Quit: zzolo]
[01:23:49] <t12> i also sort of wonder if the conical thing
[01:23:55] <t12> was due to wear on the grinding bid?
[01:23:57] <t12> bit?
[01:26:36] <andypugh> DaViruz: Yes, but, he needs to find a 4.5MT good bar, and that sounds non-tivial.
[01:28:08] <DaViruz> 4.5MT?
[01:28:48] <DaViruz> oh morse taper?
[01:31:31] <t12> maybe a way to look at it is
[01:31:42] <t12> does the error induced by having to 4.5 -> adapter -> test bar
[01:31:52] <t12> make aligning off a test bar not worth it
[01:32:25] <andypugh> It mght, it might not. How do you tell?
[01:32:43] <DaViruz> by rotating it and taking several measurements
[01:33:02] <andypugh> If you machine a bar, is it cylindrical? That is all that really matters
[01:33:27] <DaViruz> if you can rotate something it's trivial to tell taper from non-paralellism
[01:33:43] <DaViruz> if you machine a short bar and a long bar you will get different tapers
[01:33:55] <DaViruz> if you machine bars of different materials you will get different tapers
[01:34:33] <DaViruz> workpiece flex due to tool load will be significant compared to headstock alignment
[01:35:01] <andypugh> A very fat bar might tell you more,
[01:35:59] <DaViruz> yeah sure, if you can keep the length-diameter ratio under 3:1 or something like that it will probably give good numbers
[01:36:46] <t12> well
[01:36:56] <t12> i'm going to attempt to get the jaws closer to proper
[01:37:36] <andypugh> Can you borrow a very good chuck?
[01:38:23] <t12> maybe
[01:38:27] <t12> this is the chuck i have to use anyway
[01:38:33] <t12> if i have to grind it now, and again later thats ok
[01:38:38] <t12> assuming i dont run out of tooth heh
[01:38:42] <t12> i dont think i will though

[02:14:17] <andypugh> It looks sensible. I am trying to think how expanding out into a ring is different. It would certainly use the wrong side of the scroll and teeth, so this way is better in that sense.

[03:12:12] <andypugh> I think you need to move faster.
[03:12:14] <BHSPiMonkey> andypugh: sorry, I just realized you were talking to me
[03:12:29] <AR_> yeah usually burning = sitting too long in one spot
[03:12:33] <AR_> increase feedrate

[03:12:39] <BHSPiMonkey> yeah
[03:12:50] <andypugh> But it's a balance beween breaking bits and burning the wood.
[03:13:06] <BHSPiMonkey> this is my first, and I have no idea what are good rates/plunge depths to use with this tool/material/bit
[03:13:21] <BHSPiMonkey> so I'm using 100mm/min I think
[03:13:54] <AR_> what i usually do is
[03:13:58] <AR_> guess
[03:14:02] <AR_> and hope for the best
[03:14:08] <BHSPiMonkey> 5000mm/sec
[03:14:14] <AR_> if it seems too slow, use feed rate override
[03:14:14] <BHSPiMonkey> GO
[03:14:23] <AR_> or too fast
[03:14:25] <AR_> etc
[03:15:17] <BHSPiMonkey> override in linuxcnc, I'm assuming you mean?
[03:16:10] <andypugh> on my mlll the feedrate overide goes to 100x, I have so little clue. Lathes I know, mills are new.

[03:46:25] <r00t4rd3d> take that out and through it in the garbage
[03:46:31] <BHSPiMonkey> heh
[03:47:20] <BHSPiMonkey> so what characteristics make it so wrong to use? shape of the tip, flute configuration/direction? (I know it's not carbide and that doesn't help)
[03:47:48] <r00t4rd3d> they are made to grind drywall not cut wood
[03:48:03] <r00t4rd3d> its how they are fluted
[03:48:38] <r00t4rd3d> put the bit all the way to the right in your case in that bitch and cut something
[03:48:44] <BHSPiMonkey> heh
[03:49:00] <r00t4rd3d> night and day different
[03:49:06] <r00t4rd3d> no smoke
[03:49:07] <BHSPiMonkey> I might at least keep using this bit for the mirror image counterpart of the piece I just finished cutting, just so they match
[03:49:46] <r00t4rd3d> or you could break something cause the bit is dragging and not cutting
[03:50:00] <BHSPiMonkey> but I see what you're saying. this one's doing a lot of stupid rubbing instead of chopping
[03:50:10] <BHSPiMonkey> hence the heat
[03:50:38] <r00t4rd3d> if you are cutting wood and its smoking, gernerally some isnt right
[03:50:43] <r00t4rd3d> something
[03:50:54] <r00t4rd3d> alittle smoke is okay
[03:51:03] <BHSPiMonkey> well, there wasn't any visible smoke or anything
[03:51:14] <BHSPiMonkey> it just smelled a little like burning wood
[03:51:14] <r00t4rd3d> vacuum?
[03:51:52] <BHSPiMonkey> I sat there and held a vacuum hose by the bit to draw in the particles and keep them from floating out into the room
[03:52:10] <r00t4rd3d> sucking up the smoke too
[03:52:16] <BHSPiMonkey> but even when I put the vacuum down, it wasn't smoking
[03:52:50] <BHSPiMonkey> also I did the job in 1mm steps, which it was able to handle without any visible dragging or pain
[03:53:16] <r00t4rd3d> i bet when you cut with the right bit it sounds totally different
[03:53:18] <BHSPiMonkey> I might try 1.5 next time? idk
[03:53:51] <BHSPiMonkey> 99.995% of the sound during the job came from the tool simply being powered on :) coming into contact with the wood didn't change the sound much anyway
[03:54:25] <BHSPiMonkey> it made some additional noise when it bumped the sides of the toolpath a couple times
[03:54:37] <BHSPiMonkey> but yeah, this tool is a screamer

[03:58:22] <r00t4rd3d> those tiny bits with the orange collar i doubt you will ever use
[03:58:30] <r00t4rd3d> they for like pcb milling and shit
[03:59:07] <t12> does anyone make a cutting fluid that contains something that smokes at specific temps
[03:59:51] <r00t4rd3d> any oil will smoke sooner or later
[04:02:30] <t12> i mean more like
[04:02:37] <t12> some indicator to not cut too hot

[12:31:54] <jthornton> oh no, I'm learning how to count in hex
[12:32:47] <archivist> oh F00x
[12:33:36] <jthornton> playing with AVR Studio 4 and a C program atm
[12:34:15] <archivist> I am an AVR fee zone
[12:34:17] <archivist> free
[12:34:46] <jthornton> lol
[12:34:58] <jthornton> are you in a pic zone?
[12:35:27] -!- TekMason has quit [Ping timeout: 245 seconds]
[12:35:32] <archivist> yes I have made a few thousand PIC clocks
[12:36:34] <jthornton> is there any difference between AVR and PIC other than the manufacturer?
[12:37:12] <archivist> price and instruction set
[12:37:44] <jthornton> how easy is it to program a PIC?
[12:37:45] <archivist> it was price that made me go the PIC route
[12:38:07] <archivist> programming PIC is not the easiest
[12:38:19] <jthornton> what software do you use to program with?
[12:38:47] <archivist> I used the MPLAB assembler
[12:39:37] <jthornton> so you program them in assembly?
[12:39:37] <archivist> bought the Microchip programmer as we wanted some reliability rather than the homebrew stuff one sees on the net
[12:39:55] <archivist> yes I use assembler
[12:40:09] <jthornton> I even have a Peter North Assembly Language book somewhere
[12:40:53] <jthornton> are the chips price a big difference or the progammer pricing?
[12:41:22] <archivist> these days I think the prices are more even
[12:42:18] <archivist> there is a freenode channel for AVR users (never been there though)
[12:44:13] <jthornton> by golly there is
[12:44:31] <jthornton> 156 folks on line
[12:44:46] <archivist> choices for ease of use and one offs is different to a few thousand in production
[12:44:49] <jthornton> at this point I think c would be easier to do for me
[12:45:09] <jthornton> yea, I would be doing one offs

[13:28:49] <Tom_itx> pics have banked memory which can be a pita
[13:28:57] <Tom_itx> and used to be the tools weren't free
[13:29:09] <Tom_itx> not sure about now... got into avr and never looked back
[13:30:17] <Tom_itx> i used picbasic pro and ccs c on pic back then
[13:43:18] JT-Shop-2 is now known as JT-Shop
[13:43:54] <JT-Shop> Tom_itx: I managed to do a c program in AVR studio for a amega16 this morning and almost understand what I did LOL
[13:46:16] -!- motioncontrol has quit [Quit: Sto andando via]
[13:47:45] <Tom_itx> cool
[13:47:51] <Tom_itx> did you install winavr?
[13:48:49] <Tom_itx> probably so since studio relies on it...
[13:49:26] -!- mk0 [mk0!~Orr@178.120.126.191] has joined #linuxcnc
[13:49:49] <JT-Shop> yes I had to do it twice as it turns out you need to install winavr first
[13:49:56] <Tom_itx> :)
[13:50:09] <Tom_itx> wanna try it witout studio now?
[13:50:38] <Tom_itx> all i really use stuido for is to download the hex file to the chip
[13:50:54] <Tom_itx> i write the code in programmers notepad and compile it right there
[13:51:30] <r00t4rd3d> http://www.highlandwoodworking.com/manualwoodthreader128tpi.aspx
[13:51:59] <JT-Shop> can you run the sim from there?
[13:52:00] <Tom_itx> studio 6 has winavr builtin to it
[13:52:00] <JT-Shop> I won't have time to work on it this morning, going on a poker run in a bit
[13:52:00] <Tom_itx> no
[13:52:10] <Tom_itx> that's just in studio
[13:52:10] <Tom_itx> there are 2 sim files too depending on which chip you have
[13:52:21] <Tom_itx> i'm not sure why they split them

[13:52:34] <Tom_itx> that's fine, i have a job in an hour anyway

[14:03:22] <Tom_itx> jthornton, btw the mega16 is an older chip and doesn't have alot of the features the newer ones have. it's not obsolete by any means though
[14:04:31] <JT-Shop> what's a newer chip?
[14:04:40] <Tom_itx> those i mentioned
[14:04:46] <Tom_itx> like the 48 8 168 etc
[14:04:49] <Tom_itx> there are others
[14:04:54] <JT-Shop> ok
[14:05:01] <Tom_itx> do you need a 40 dip?
[14:05:10] <JT-Shop> LOL, I don't have a clue
[14:05:13] <Tom_itx> those ^^ are 28 pin
[14:05:23] <Tom_itx> 16 and 32 are 40 dip
[14:05:31] <Tom_itx> i've got a few of the 32's
[14:05:36] <Tom_itx> still use em
[14:06:02] <Tom_itx> not the 8 rather 88
[14:06:10] <Tom_itx> the 8 seems to be a pita sometimes
[14:06:33] <JT-Shop> this a 48? http://www.digikey.com/product-detail/en/ATMEGA48A-PU/ATMEGA48A-PU-ND/2271048
[14:06:34] <Tom_itx> although it's pin compatible with the 48 88 168 328 it's an older chip
[14:06:39] <Tom_itx> yeah
[14:08:03] <Tom_itx> it's got adc, pwm, usart spi i2c etc
[14:08:03] <JT-Shop> the bigger number has more?
[14:08:10] <Tom_itx> more flash
[14:08:12] <Tom_itx> same features
[14:08:23] <Tom_itx> in a series of chips that is
[14:09:07] <Tom_itx> those i mentioned ^^ are all basically the same just more flash
[14:09:19] <JT-Shop> what's the difference between the mega and tiny?
[14:09:28] <Tom_itx> tiny are smaller
[14:09:50] <JT-Shop> the 88 mega and tiny are both 28 dip
[14:09:54] <Tom_itx> still have alot of the good features though
[14:10:00] <Tom_itx> you just gotta pick and choose
[14:10:11] <Tom_itx> check the feature list
[14:10:22] <Tom_itx> i haven't done alot of the tinys myself
[14:10:24] <Tom_itx> just a few
[14:10:31] <Tom_itx> the 2313 is one i've used
[14:10:57] <Tom_itx> i started using the tiny10 when i was developing my programmer
[14:11:26] <Tom_itx> you can get atmel branded programmers too if you want
[14:11:42] <Tom_itx> atmel typically has been more hobbyist friendly than pic over the years
[14:11:43] <JT-Shop> does it make any difference?
[14:11:46] <Tom_itx> nope
[14:12:00] <Tom_itx> you can make a programmer with 2 resistors if you really wanted
[14:12:03] <JT-Shop> does yours have the easy in and out socket thing?
[14:12:16] <Tom_itx> no, you would need a breaboard

[14:13:12] <Tom_itx> the right plug
[14:13:28] <Tom_itx> i'll toss one in if you want
[14:13:41] <Tom_itx> nobody uses the 6 to 10 anymore
[14:14:04] <Tom_itx> the 10 pin was the old programmer plug, nowdays nearly everyone has gone to the 6 pin
[14:14:15] <Tom_itx> the extra pins were ground and a status led
[14:14:19] <JT-Shop> is that just for the tiny
[14:14:26] <Tom_itx> no
[14:14:36] <Tom_itx> my programmer will work on all the 8bit avrs
[14:14:42] <Tom_itx> the 32bit are jtag only

[14:17:00] <Tom_itx> GND
[14:17:14] <Tom_itx> in the case of the PDI and TPI there are only 4
[14:18:09] <Tom_itx> there's a couple sample programs there if you wanna play
[14:18:14] <Tom_itx> that's why i wrote that
[14:18:21] <Tom_itx> to get noobs started
[14:19:27] <JT-Shop> ok that is great
[14:20:17] <Tom_itx> you will likely get more online support using avr over pic too
[14:20:27] <Tom_itx> since they're more hobby friendly
[14:22:26] <Tom_itx> i focused on those chips since ardweenie started out with them and they are rather popular

[14:24:43] <Tom_itx> like the t13 and probably your choice of teh 48 88 168 328
[14:24:50] <JT-Shop> ok
[14:24:54] <Tom_itx> i'll send you one if you need

[14:25:11] <JT-Shop> you get the order?
[14:25:13] <Tom_itx> along with the plug thing
[14:25:18] <Tom_itx> didn't look

[16:34:45] <tjtr33> that is one long thread on gscreen
[16:39:54] <skunkworks> that was an attempt to show how flexable gscreen is iirc
[16:41:37] <skunkworks> gscreen as is a few other screen sets are in the development branch of linuxcnc
[16:45:31] <tjtr33> thx, I'm still reading the thread, CMorely, JT, Nick from cncRU, mha's git repo... this is thick!
[16:47:42] <tjtr33> i did come across the idea of using estop to turn off the machine.
[16:47:43] <tjtr33> we used to have a 'sleep' button, if it was on, and you ended the running porgram OR hit estop, the machine had power removed. so it depended on this 'sleep' btn.
[17:07:56] <tjtr33> hey! gscreen, even gscreen-industrial is just built into my rip of master ( 2.6.0~pre)
[17:07:58] <tjtr33> it would've been easy to say 'its in master'

[18:56:58] <Connor> and is that you talking? :)
[18:59:15] <andypugh> Connor: Yes, to both.
[19:02:09] <Connor> Interesting mill.
[19:04:24] <andypugh> It's a "Universal" so it has a horizontal and a vertical spindle, and the table swings. The table-swing is especially useful for gear hobbing.
[19:04:37] <Tom_itx> that rotary sure takes up alot of space
[19:05:11] <Connor> What was that gear for ?
[19:05:33] <andypugh> It's a timing pulley for the X axis drive of the mill itself.
[19:06:58] <IchGuckLive> today is gear day ?
[19:07:00] <andypugh> The rotary can go right on the end of the bed, I get a pretty good length between centres. The 4-jaw chuck is a big part of it.
[19:07:19] <IchGuckLive> http://foengarage.de/gears.html gears i made in CSS
