[00:29:55] <Valen> CaptHindsight: yup ;->
[00:30:24] <Valen> we were planning on using the EG as the base then just wetting out the CF over it
[00:32:22] -!- rob_h has quit [Ping timeout: 272 seconds]
[00:32:40] <Valen> I have been concerned about bolting steel rails to the EG
[00:32:55] <Valen> but the mix we are using seems to have about the same thermal expansion as steel
[00:33:46] <Valen> do you know of any paper or other such, detailing information on different resins and the properties of a resultant EG mix?
[00:45:18] <furrywolf> is eg intended to be a structual material?
[00:46:29] * furrywolf usually associates it with yuppie countertops, not useful objects...
[00:47:51] <SpeedEvil> Valen: it's all about fill fraction and strains
[00:48:06] <SpeedEvil> Valen: If you have CF, the CF utterly dominates the resin at normal fill factors
[00:48:32] <SpeedEvil> the CF composite has the CTE of CF, the resin doesn't do much, as it is so much enormously flexier
[00:49:58] <furrywolf> the cf sets the properties in two dimensions... in the third, especially under S-shaped stresses, the epoxy is the weak point...
[00:50:07] <furrywolf> assuming normal layered construction
[00:50:31] <furrywolf> same with fiberglass
[00:50:34] <SpeedEvil> http://www.academia.edu/3307494/Study_of_Thermal_Expansion_in_Carbon_Fiber_Reinforced_Polymer_Composites
[00:50:44] <Valen> furrywolf: lots of fancy pants manufacturers are using epoxy granite for machine tool bases it seems
[00:50:47] -!- patrickarlt has quit [Remote host closed the connection]
[00:50:51] <SpeedEvil> Results of composite samples indicated that CTE in the directions perpendicular to the fibers ranged from 35 to 57 µm/(m·°C) and depicted same order of magnitude of resin samples. On the other hand, CTE in fiber dominated directions was negative or close to zero.
[00:52:03] <furrywolf> also, I want to see the long-term stability of carbon fiber... consider how utterly poorly fiberglass does with time, due to failure of the resin.

[01:43:52] <zeeshan> why is it so hard to find feeds for a holesaw
[01:43:55] <zeeshan> i see sfm
[01:43:59] <zeeshan> not feed..
[01:44:29] <cradek> probably because it's hard to guess how many teeth are actually cutting
[01:44:33] <SpeedEvil> Because they're usually used by people that don't read them?
[01:44:55] <cradek> better to put it on the drill press
[01:45:12] <SpeedEvil> cradek: doesn't matter how many teeth are cutting - the feed in princple is the same
[01:45:12] <Tom_itx> crank it down until it smokes then back off just a bit...
[01:45:17] <archivist> they need peck drilling due to chips
[01:45:18] <zeeshan> cant put in drill press
[01:45:36] <Tom_itx> zeeshan i'd calculate it like a flycutter of same diameter
[01:45:57] <SpeedEvil> But - sane chip loading for one tooth doesn't really work for all the teeth in many cases simply as it's not rigid enough
[01:45:58] <cradek> SpeedEvil: nope. if it says .002/tooth chip load, how many inches per minute do you feed it? no way to know
[01:46:01] <Tom_itx> you want slower rpm
[01:46:16] <Tom_itx> cradek count the teeth
[01:46:26] <Tom_itx> but i still wouldn't feed it that much i think
[01:46:31] <cradek> they aren't all cutting. probably three are.
[01:46:44] <SpeedEvil> cradek: .002/tooth chip load surely means that if you've got 100 teeth, .2"/rev?
[01:46:44] <Tom_itx> heh yeah probably
[01:46:44] <cradek> same with woodruffs etc
[01:46:52] <archivist> and those three jamb up
[01:46:56] <SpeedEvil> That sounds about right
[01:47:11] <zeeshan> http://i.imgur.com/o3TbmNC.png
[01:47:14] <cradek> SpeedEvil: I made up those numbers AND you're missing the point :-)
[01:47:18] <SpeedEvil> - with the caveat that that will snap the shaft, and you can only peck a tiny amount at that load
[01:47:18] <zeeshan> i gotta make 8 of those highlighted things
[01:47:22] <zeeshan> i mean 6
[01:47:27] <zeeshan> https://www.youtube.com/watch?v=Mo2GXnfKyA8
[01:47:36] <zeeshan> i was doing it like this a couple y ears ago
[01:47:49] <zeeshan> but i didnt have the most optimal speed and feed doing
[01:47:51] <zeeshan> *going
[01:47:53] <zeeshan> i just did it by feel
[01:48:01] <zeeshan> (was feeding manually)
[01:48:03] <cradek> don't you have a cnc mill?
[01:48:15] <cradek> that's just circular interpolation with an end mill
[01:48:25] <zeeshan> yes i do
[01:48:26] -!- patrickarlt has quit [Ping timeout: 265 seconds]
[01:48:32] <zeeshan> was thinking it'
[01:48:36] <zeeshan> it'd be faster with the lathe
[01:48:54] <Tom_itx> are they all the same?
[01:48:58] <zeeshan> ya
[01:49:01] <Tom_itx> fixture them and ballnose the end
[01:49:13] <zeeshan> i wanna use the lathe
[01:49:17] <zeeshan> but i want the correct feed rate
[01:49:26] <SpeedEvil> cradek: ah - yes - I now see why number of teeth engaged mattars in reflection
[01:49:43] <zeeshan> SpeedEvil: feed per tooth ~0.001 i'd think
[01:49:52] <zeeshan> actually i have no clue for a bandsaw blade
[01:49:59] <zeeshan> i think 0.001 would be reasonable
[01:50:17] <archivist> flat sheet, plasma and then roll
[01:50:24] <zeeshan> stop trolling me :(
[01:50:37] <zeeshan> gimme feeed!!!
[01:50:49] <archivist> no, its the wrong way
[01:50:53] <zeeshan> i gotta run it at 160 rpm
[01:50:59] <zeeshan> but how much feed
[01:51:12] <zeeshan> can i assume half the teeth are in enagement
[01:51:14] <zeeshan> engagement
[01:51:28] <cradek> I wish our cnc mills had something like what you get with a band saw or drill press or even edm: push a reasonable amount and let the thing feed however fast it wants
[01:51:46] <Tom_itx> zeeshan what's the sfm at 160rpm?
[01:51:54] <Tom_itx> calculate the diameter
[01:51:59] <zeeshan> cradek: maybe w/ force feedback
[01:52:07] <zeeshan> specifically Fq (thrust/ feed force)
[01:52:13] <zeeshan> sfm is 100
[01:52:16] <zeeshan> dia is 2.5
[01:52:20] <furrywolf> auger stand built
[01:53:23] <zeeshan> this thing is 6 teeth per inch
[01:53:49] <zeeshan> 1 ipm?
[01:53:50] <zeeshan> lol
[01:53:56] <Tom_itx> slow for sure
[01:54:20] <zeeshan> i really like doing it on the lathe over mill
[01:54:30] <zeeshan> because i dont have to to keep zeroing out the work piece
[01:54:40] <zeeshan> i can eyeball the end of the tube, and chop it off
[01:54:45] <zeeshan> load another, do the same
[01:55:07] <zeeshan> ill try 2 ipm and 1 ipm
[01:55:15] <zeeshan> and go by sound
[01:55:45] <zeeshan> yay my tube notcher video has 800 views, thank you!
[01:58:24] <cradek> hahah wow what a piece of crap:

[02:00:04] <zeeshan> lol
[02:00:08] <zeeshan> thread wears out
[02:01:52] <furrywolf> http://fw.bushytails.net/augeronstand01.jpg auger stand/christmas tree stand. :)
[02:02:13] <zeeshan> nice auger
[02:08:12] <furrywolf> it's surging a bit at full throttle, unloaded at least... might need to clean carb/fuel filter.
[02:08:29] <furrywolf> or just run some fresh gas through it digging some holes and see if it goes away
[02:08:59] <zeeshan> it needs NAWZ
[02:09:09] <furrywolf> it was running when that photo was taken. lol
[02:09:35] <zeeshan> how do you hold this thing
[02:09:38] <zeeshan> i see the 4 handles
[02:09:42] <furrywolf> one person on either side
[02:09:52] <zeeshan> where does the auger stick out of
[02:09:59] <zeeshan> towards the red end?
[02:10:08] <furrywolf> the bottom
[02:10:14] <zeeshan> oh
[02:10:25] * furrywolf googles for a photo
[02:10:27] <zeeshan> that would be a useful tool to have =/
[02:10:34] <zeeshan> i wanna build a deck
[02:10:43] <zeeshan> and a shead
[02:10:44] <zeeshan> *shed
[02:10:58] <furrywolf> http://www.groundhoginc.com/product_images/5-detail-3.jpg
[02:11:21] <zeeshan> looks like its pretty much self feeding
[02:11:48] <furrywolf> I suspect it's off in that photo. in reality operating one sucks. I also note a lack of exhaust or flying dirt.
[02:12:13] <zeeshan> :D
[02:12:14] <furrywolf> it's trying to push each person sideways with a hundred pounds of force or so. you don't just stand there like that. :P
[02:12:25] <zeeshan> ok im gonna auger some metal
[02:12:28] <zeeshan> BRB :D
[02:14:05] <furrywolf> http://www.groundhoginc.com/product_images/12-product-image.jpg somewhat more realistic. :P

[03:58:37] <furrywolf> I have a small brushed DC motor that's running at half speed. if I push on either brush, it speeds up. I cleaned the commutator the best I could through the slots in the motor. It looks like the brushes got very hot at some point. Did I somehow detemper the springs or something?
[04:00:33] <furrywolf> of the three electric starters that are in the parts pile, zero have working motors. now I know why they're off...
[04:05:36] <furrywolf> bah. I just pushed one the brushes sideways, and it stayed there. springs aren't.
[04:08:24] <furrywolf> I guess I need to take it apart, which ain't going to be fun... the brush+bush plate is crimped in to the housing rather well.
[04:09:29] <furrywolf> why are honda parts so fucking expensive? I can buy a much larger, much less plasticy full-size automotive starter for half what they want for the little plastic generator one

[05:43:11] <Valen> so introductory engineering question, as an exercise I rearranged hookes law to work out how much area is needed to have a set amount of elongation under a load. I get Area = Force / ((change in length / length) * youngs modulus)
[05:44:51] -!- anth0ny_ has quit [Quit: anth0ny_]
[06:16:56] <zeeshan> that is only v alid in the linear elastic region tho

[06:20:46] <archivist> youngs modulus can be pretty similar for different materials, shape matters more
[06:21:56] <zeeshan> i took it back because under uniaxial tension
[06:21:57] <zeeshan> you

[06:44:01] <Valen> zeeshan / archivist, I was looking at the general case, if the underlying maths is right then I understand how I-Beams work ;->
[06:44:42] <Valen> and it would imply that for a given I Beam (with an ideal upright) increasing the thickness of the flats would decrease the deflection for a given load
[06:45:31] <archivist> the elasticity of the steel is a constant, I the shape that makes a good beam
[06:46:08] <Valen> I get that, but is what I said right?
[06:46:25] <Valen> a thicker flat would reduce the deflection?
[06:47:37] <archivist> deeper reduces it more than thickening the edge
[06:48:35] <archivist> because the elasticity is constant
[06:49:36] <Valen> yeah, the trig functions mean that it is going to be seeing more tension for the same deflection?
[06:49:47] <archivist> if you get Roarkes Stesses and strains book you will get all the maths for the shape factor
[06:50:09] <Valen> (I'm not trying to design a beam yet, I'm trying to understand the maths behind the whole thing ;->)
[06:50:47] <archivist> actual title Roark's formulas for stress and strains

[07:19:43] <zeeshan> and even in bending
[07:19:44] <zeeshan> its diff
[07:19:56] <zeeshan> geometry comes into play
[07:20:23] <archivist> and then....why you no add webs there?
[07:21:48] <zeeshan> basically comes down to sigma = Mc/I
[07:21:56] <zeeshan> I is based off of geometry
[07:22:21] <zeeshan> c is the distance from the neutral axis to the outermost fibers of the beam
[07:22:57] <zeeshan> m is the moment you're applying, so basically you find out that the higher the I , the less the amount of stress
[07:23:16] <zeeshan> I being second moment of area
[07:23:26] <archivist> but then the beam is connected to structure, screwing with simple calcs
[07:23:41] <toastyde1th> FUCK IT, USE THE MISSLE EQUATIONS FOR EVERYTHING!
[07:23:44] <zeeshan> you model it individually
[07:24:00] <archivist> use FEM :)
[07:24:06] <zeeshan> benefit of linear elasticity!
[07:24:08] <zeeshan> superposition
[07:24:12] <zeeshan> you can break it up into smaller problems
[07:24:26] <zeeshan> fem is good, but its dangerous too
[07:24:44] <zeeshan> if you havent done the theory, you might get weird results because the model was wrong
[07:24:58] <zeeshan> but the person wouldn't realize it's "weird" cause they havent understood the theory

[14:33:23] <Tecan> ssi, one thing to watch specially on model planes is the wings ripping off during a barrel roll
[14:33:28] <_methods> side mounted umbrella?
[14:33:50] <ssi> Tecan: a proper barrel roll doesn't have much G load :P
[14:34:34] <ssi> yea that is a wacky toolchanger
[14:34:45] -!- md-2 has quit [Remote host closed the connection]
[14:35:30] <cradek> weird, it pushes the tool down out of the taper and it hangs there in mid air until the hand grabs it
[14:36:10] <cradek> I've never seen anything like that - I wonder how the drawbar works
[14:37:20] <ssi> _methods: do you have a truck&trailer for moving machines?
[14:37:32] <_methods> well it depends
[14:37:38] <_methods> i mean if it's big we get riggers
[14:37:44] <ssi> nah, not too big
[14:37:48] <ssi> want to go buy some robots?
[14:37:52] <_methods> but if it's small stuff we have a 20,000 lb 5th wheel trailer
[14:38:12] <_methods> how many and how much?
[14:38:16] <ssi> http://www.ebay.com/itm/Kuka-Roboter-KR150L-150SP-2-Robot-Arm-No-Controller/271659536669#viTabs_0
[14:38:19] <ssi> they have 10 of them
[14:38:22] <ssi> I wouldn't mind 2
[14:38:27] <ssi> they're 2700lb apiece
[14:38:45] <_methods> yeah man those things are pretty big
[14:38:54] <_methods> hmm only $1k
[14:38:57] <ssi> yeah
[14:39:05] <ssi> it'd be a PERFECT playtoy for a linuxcnc robot
[14:39:08] <_methods> yeah
[14:39:13] <Tensaiteki> yes this is the mill at TX RX labs
[14:39:17] <ssi> they actually have controls and pendants for them
[14:39:23] <ssi> but they want 3x as much for a control as they do for the arm
[14:39:27] <_methods> yeah
[14:39:30] <_methods> that's usually the case
[14:39:38] <ssi> and 90% of the fun for me is building the control
[14:39:39] <_methods> but for a retrofit linuxcnc
[14:39:41] <_methods> yep
[14:40:00] <ssi> I want to set one up with a spindle and carve props
[14:40:04] <_methods> id love to grab one i just dont have room for it
[14:40:05] <ssi> that'd be an awesome 6 axis mill
[14:40:28] <_methods> when cat reman closed here they were going to jsut give me their robots
[14:40:34] <Tensaiteki> The drawbar was one of the biggest problems we had. Took forever to figure out how it worked
[14:40:35] <_methods> none of the other cat plants wanted them
[14:40:38] <ssi> dang :/
[14:40:47] <ssi> I have room for two of these pretty easily
[14:41:00] <cradek> Tensaiteki: awesome, glad to see it going. It was only barely moving when I was there. congrats.
[14:41:02] <ssi> not really room to OPERATE two
[14:42:05] <_methods> yeah i got a trailer and truck i could use the boss might want to charge though for a va to atl trip though hehe
[14:42:20] <Tensaiteki> cradek: now that school is done for the year, I've been working full-time at the Labs getting the powerhawk going and working on convertin the press-brake
[14:42:50] <ssi> lolol
[14:43:05] <ssi> I'll come up with something
[14:43:19] <cradek> Tensaiteki: I sure enjoyed our time there. It's a neat place you folks have.
[14:43:22] <ssi> maybe I'll just break down and buy a rollback like I've been threatening to for years
[14:43:36] <_methods> yeah that would work
[14:43:43] <ssi> I want either a rollback or a flatbed dually diesel truck
[14:43:51] <_methods> if you just want 1 those drop down trailers would be perfect
[14:44:22] <ssi> I just don't have a truck
[14:44:34] <ssi> I have a utility trailer I pull behind my car
[14:44:38] <ssi> but this is just a smidge too much for that
[14:44:44] <ssi> and I'd be worried about topheaviness heheh
[14:44:53] <Tensaiteki> cradek: everyone is welcome back any time. And, for the record, our part of Houston didn't flood.
[14:45:19] <_methods> http://www.fallsway.com/drop-deck-trailers
[14:45:29] <_methods> i need to get one of those
[14:46:00] <ssi> I have a forklift, so I'm less concerned about a drop deck
[14:46:04] <MattyMatt> shame the law doesn't allow electric motors in a trailer
[14:46:16] <_methods> oh yeah i don't have a forklift
[14:46:24] <cradek> Tensaiteki: that's good, I was thinking about you folks when I saw those photos.

[14:49:06] <CaptHindsight> MattyMatt: what's this law about electric motors and trailers?
[14:49:32] <Tensaiteki> cradek: yeah, when Houston was young, they built on the parts that didn't flood, first. There's an advantage to being in the older neighborhoods. The suburbs and highways were built on the flood plains.
[14:49:35] <MattyMatt> any kind of motor, and legally you're a semi aren't you?
[14:49:42] <_methods> i just have a tacoma so i don't think i'll be much help haulin that robot

[14:53:57] <ssi> http://atlanta.craigslist.org/wat/cto/5043148658.html
[14:53:57] <CaptHindsight> if they have a forklift you could lay them down in a trailer

[15:10:35] <CaptHindsight> 28mpg at 70 mph sounds good in the country
[15:10:36] <ssi> prolly
[15:10:52] <ssi> I'd prefer a rollback because that's about the only way to move a forklift
[15:10:57] <ssi> but they're far more expensive
[15:10:59] <ssi> and harder to store
[15:11:26] <CaptHindsight> what is top speed on the highways in Atlanta now, theoretically 55, but usually 25? :)
[15:11:30] -!- moorbo has quit [Remote host closed the connection]
[15:11:49] <ssi> more like 90
[15:11:52] <ssi> depends on the time of day
[15:12:05] <ssi> they actually raised a bunch of the limits inside the perimeter from 55 to 65
[15:12:09] <ssi> and everything outside is 65 or 70

[15:27:29] <_methods> i'm suprised they don't have a cage around that
[15:28:05] <ssi> that's the same arm

[15:28:20] <_methods> irbcam?

[15:28:39] <CaptHindsight> cages are for wimps or osha compliance
[15:29:00] <_methods> heh
[15:29:11] <_methods> i've seen robot arms do some pretty sketchy stuff
[15:29:28] <_methods> albeit was in a new CV part detection area
[15:29:39] <_methods> where the arm was supposed to be stacking parts by type
[15:29:50] <_methods> it just starting chuckin parts across the shop
[15:29:50] <CaptHindsight> the factory tech don't trust them
[15:30:07] <_methods> good sized bent sheet metal parts lol
[15:30:28] <_methods> the cage got a bit taller after that
[15:30:49] <CaptHindsight> say an encoder has come loose on a joint, the servo might whip the arm several inches until it gets an error and stops
[15:31:16] <_methods> i know for a fact i wouldn't be standing that close to it
[15:31:23] <CaptHindsight> that why that robot arm ride is nuts

[15:50:17] <ssi> need a drill?
[15:51:23] <archivist> pecentage broken....
[15:51:53] <CaptHindsight> ssi: i was just thinking that at some point those drives are just an amp and power supply. Could they be hacked to be used just as servo amps?
[15:52:02] <ssi> maybe
[15:52:13] <ssi> I tried to do some research along those lines and didn't have much luck
[15:52:20] <archivist> is there a full manual?
[15:52:21] <CaptHindsight> oh well
[15:52:25] <ssi> part of the reason I wanted to use those drives was because they do sinusoidal commutation
[15:52:34] <CaptHindsight> don't think so they are by Parker
[15:52:38] <ssi> which is a bit more complex than just an amp and a power supply
[15:53:24] <ssi> it blows my mind that they take a simple servo drive, the GV, and add crazy computer to it to make the GV6, but disable the simple control
[15:53:37] <skunkworks> for most things trapazoidle is just fine
[15:54:08] <ssi> skunkworks: well in my particular case I wanted sinusoidal drive because I don't have hall effects in my VMC's servos, I have fanuc 4-bit commutation
[15:54:26] <ssi> and so I was gonna have to do some work to fake the 6 state hall signals, and it doesn't align exactly so it's sorta lumpy
[15:54:57] <ssi> with a sinusoidal drive, it'd only be lumpy for one rev, then it'd smooth out when the encoder references and the drive switches over to sinusoidal commutation
[15:56:30] <skunkworks> pico systems makes a converter box i think fanuc to trap...
[15:56:36] <ssi> yes, I'm aware
[15:56:39] <ssi> and I flat refuse to buy it
[15:56:47] amnesic_away is now known as amnesic
[15:56:49] <skunkworks> heh
[15:57:17] <skunkworks> I also think hal would do it
[15:57:33] <ssi> yeah there's a hal component for it
[15:57:35] amnesic is now known as amnesic_away
[15:57:55] <ssi> I think what I'm actually going to do is buy an 8i20 and see how well that works as a drive, and do the commutation in hal
[15:58:14] <ssi> then I can use all the BE25A20 drives I have for my robut
[15:58:15] <ssi> :D
[15:58:32] <ssi> and the parkers can remain paperweights

[17:22:09] <ssi> pcw_home: can you give me a hand selecting an IO daughterboard?
[17:23:35] <pcw_home> sure
[17:24:11] <ssi> I have a 5i25/7i77 kit for running this VMC, and I still haven't had time to build external commutation converters for the fanuc servos
[17:24:19] <ssi> I'm thinking I should just use the bldc component to do that in software
[17:24:29] <ssi> but it's gonna take a bunch of IO...
[17:24:44] <ssi> I'm assuming those fanuc commutation tracks output like an encoder, which I guess is 5V ttl basically
[17:25:14] <pcw_home> the drives need the Hall signals?
[17:25:27] <ssi> yes, if I use the AMC drives I have, they need hall signals
[17:25:43] <ssi> the other option is to get 8i20s, and then I guess I'd need a 7i74 or something so I can feed each drive serial
[17:26:19] <pcw_home> yeah or maybe a 7I85 instead of the 7I77
[17:26:35] <ssi> ooh that's not a bad idea
[17:26:51] <ssi> does it have the 10V analog servo outs?
[17:27:02] <ssi> or can that all be done over 422 with the 8i20
[17:27:58] <pcw_home> Oh I forgot the AMCs need analog
[17:28:14] <ssi> well I only need the multichannel 422 if I ditch the amc and go 8i20
[17:28:45] <zeeshan> gimme amc drives
[17:28:46] <zeeshan> free
[17:28:47] <zeeshan> ty!
[17:28:48] <ssi> I just need to make sure that I end up with everything I need to run three of these servos plus a bunch of extra IO for everything else the machine needs
[17:29:22] <ssi> I was thinking about ordering a single 8i20 and trying to get it running on the spare sserial port on the 7i77.... is that feasible?
[17:29:28] <ssi> just to proof of concept the setup
[17:29:29] <pcw_home> Yeah so 7i77 for AMC, though you may still be better doing the Hall conversion in a FPGA
[17:29:48] <pcw_home> sure you can run 1 8I20 from the 7I77
[17:29:58] <ssi> with 8i20 and bldc component, will it effectively do sinusoidal commutation?

[17:30:36] <pcw_home> you may learn more about BLDC motors that you want to though...

[17:30:50] <ssi> I had a working commutation converter in a cpld
[17:31:02] <ssi> it just wasn't good because I didn't have a clock to use the encoder lines for sinusoidal
[17:31:45] <ssi> my only concern about the 8i20 is the cost
[17:32:28] <ssi> 7i85 is inexpensive though, and I can use the 7i77 I have for another project
[17:33:50] <ssi> I'd need a separate gpio board if I went to 7i85 though

[17:35:09] <pcw_home> s/hall/fanuc/
[17:35:27] <ssi> shouldn't be hard
[17:36:27] <ssi> is there something like the 7i90 with terminal blocks instead of IDC headers?
[17:38:47] <pcw_home> No but one with those .1" spring terminals might not be a bad idea
[17:39:01] <ssi> hm maybe I'll order a 7i90, a breakout/iso card for it, and an 8i20
[17:39:03] <ssi> and just experiment
[17:39:22] <ssi> if I can make it work with the 7i90 doing commutation conversion in fpga, and the amc drives, that'd be a good option
[17:39:26] <zeeshan> has anyone used an electronic air pressure regulator?
[17:39:30] <ssi> since the amc drives are already mounted and they have their own power supplies
[17:39:52] <zeeshan> it takes a 4-20mA signal and outputs a proportional pressure output?
[17:40:36] <ssi> 7i42TA out of stock :(
[17:40:44] <pcw_home> a robust adapter would use the fanuc state change as a reference then extrapolate based on encoder counts
[17:41:04] <pcw_home> There are in stock but maybe not on the store yet
[17:41:08] <ssi> ah ok
[17:41:21] <pcw_home> just got more last week
[17:41:21] <ssi> is that an appropriate breakout for what I'm trying to do?
[17:42:36] <pcw_home> probably (TTL but protection from mistakes)
[17:43:02] <ssi> TTL is adequate for the hall state outputs, isn't it?

[17:46:11] <_methods> after the apple link
[17:46:19] <ssi> oh I hadn't even looked at it yet
[17:46:19] <zeeshan> whats that extra signal from 7i42
[17:46:20] <ssi> looking now
[17:46:21] <zeeshan> to fanuc
[17:46:33] <ssi> zeeshan: 4 bit fanuc state in, hall state out
[17:46:47] <zeeshan> what does it use that for
[17:46:56] <ssi> that's the commutation conversion
[17:47:18] <ssi> pcw_home: would I need to split the encoder signal and feed both the 7i77 AND the 7i90, or can the 7i90 get the encoder data over sserial from hm2
[17:47:21] <zeeshan> so that tells the fanuc drive the current position
[17:47:23] <zeeshan> of the motor?
[17:47:27] <zeeshan> in layman terms
[17:47:30] <ssi> zeeshan: yes
[17:48:08] <ssi> pcw_home: I guess I'd need a custom hm2 driver for the 7i90 firmware that exposes input pins to hook up encoder signals from hal

[18:00:28] <ssi> have you guys seen the Σn = -1/12 proof that people have been talking about?
[18:00:33] <ssi> I dunno why this article made me think of it :P
[18:00:50] <_methods> no havne't seen that
[18:01:22] <ssi> what's Σn from n=1 to n=infinity?
[18:01:35] <ssi> in other words the sum of the sequence 1, 2, 3, 4, 5... infinity
[18:01:36] <_methods> -1/12
[18:01:37] <_methods> lol
[18:01:51] <ssi> intuitively it's infinity
[18:01:54] <ssi> but apparently it's -1/12
[18:03:18] <ssi> pcw_home: I'm ordering an 8i20, a 7i90, and a 7i42TA now. Hopefully I can cobble something up that'll work with all these parts :D
[18:03:30] <zeeshan> dont troll us ssi
[18:03:47] <zeeshan> the sum if natural numbers isn't -1/12 it diverges to infinity :P

[18:05:16] <_methods> lol
[18:05:28] <ssi> yes

[18:11:03] <ssi> Now if you run a shop like mine at CBA where we have one of every kind of computer-controlled manufacturing machine, there's maybe twenty processes that can control a computer to make something: cut with lasers, supersonic jets of water, EDM with wires, machining, plasmas, fusing, bonding. For all the attention to 3D printing, we might use 3D printers 20 percent of the time. The other 80 percent of the time other machines are faster, make higher perform
[18:11:10] <ssi> exactly
[18:11:14] <_methods> yep

[18:24:15] <_methods> Start with education. I love the maker movement and I also get irritated by the maker movement for the failure in mentoring. At something like a Maker Faire, there's hall after hall of repeated reinventions of bad 3D printers and there isn't an easy process to take people from easy to hard.

[18:33:16] <ssi> you can get clean edges from plasma if you get your height/speed/current correct
[18:33:23] <zeeshan> no no
[18:33:24] <ssi> it's hard to do by hand
[18:33:25] <zeeshan> thats not what i mean
[18:33:31] <ssi> the HAZ is still plenty weldable
[18:33:33] <ssi> it's just hard to cut heh
[18:33:34] <zeeshan> im using air to blast
[18:33:45] <zeeshan> so it rusts immediatelly the cutting edge
[18:33:47] <zeeshan> when you go to tig it
[18:33:49] <zeeshan> it welds like asshole
[18:33:58] <zeeshan> (if you dont clean it)
[18:34:04] <ssi> air plasma makes a perfectly weldable edge if it's done right

[18:43:09] <ssi> the white is already shot and masked on the upper
[18:43:09] <_methods> yeah i saw the cowl was off wasn't sure what you had going on
[18:43:19] <ssi> for some reason the guy doing the paint likes to only prep the section he's gonna paint :P

[18:43:34] <_methods> to be fair surface prep sux
[18:44:00] <ssi> yeah I know
[18:44:22] <ssi> it's just weird because he's gotta skim the pinholes full and sand it all, with finished paint under mask
[18:44:27] <ssi> seems dangerous
[18:44:48] <ssi> also, the paint they're using is the same as the paint they used on the wings when they rebuilt them

[18:45:02] <ssi> which'll be very obvious on the cowl to fuselage transition :(
[18:45:02] <_methods> exact same can?
[18:45:07] <ssi> yeah
[18:45:20] <ssi> the wings were painted in january I think
[18:45:21] <_methods> well if they didn't mix it good
[18:45:29] <ssi> it's not a paint issue, it's a color match issue
[18:45:36] <ssi> they bought a cream when they did the wings, but the fuselage is white
[18:45:41] <_methods> hmm
[18:45:50] <ssi> it's not obvious between the wings and fuse, but it'll be very obvious on the cowl

[19:55:50] <furrywolf> roycroft: a good jerk isn't working. I've found that around 400ftlbs I slip my clutch. no easy way to lock the engine...
[19:56:15] <roycroft> would bumping the starter even work then?
[19:56:23] <roycroft> might that not just cause your clutch to slip?
[19:56:37] <XXCoder> roycroft: possibly higher impact force
[19:56:53] <furrywolf> roycroft: starter is on the engine side of the clutch
[19:57:00] <roycroft> oh, yeah
[19:57:16] <roycroft> so you need to lock your flywheel
[19:57:28] <ssi> did you soak the bolt in kroil?
[19:57:29] <XXCoder> furrywolf: no way to add pipe in such way it extends your tool?
[19:57:29] <furrywolf> other suggestions found googling are strap and chain wrenches around the pulleys
[19:57:34] <furrywolf> ssi: no
[19:57:38] <ssi> I'd start there
[19:57:54] <furrywolf> XXCoder: extending my tool won't help when the problem is the crank is turning. it'll just let me turn it easier.
[19:58:05] <XXCoder> lol yeah
[19:58:23] <XXCoder> hmm
[19:58:23] <furrywolf> I like the starter motor idea. brb, breaking a craftsman socket. :P
[19:58:56] <XXCoder> lifetime warranty

[20:07:49] <furrywolf> that worked way, way too well.
[20:08:24] <furrywolf> I spent a half hour dicking with it, grunting hard, etc, when all it needed was a 1/8 second click of the key.
[20:08:45] <XXCoder> heh your car assisted in its repair

[20:24:57] <MrSunshine> hmm .. got huge vibrations going on in the machine i havent had before :/
[20:25:01] <MrSunshine> and dont know where they come from
[20:26:21] <_methods> do you live near a fault line
[20:26:31] <_methods> or a volcano
[20:26:38] <MrSunshine> haha
[20:26:44] <_methods> hehe
[20:26:46] <MrSunshine> no but machine is in a wooden structure
[20:26:47] <_methods> if yes plz run
[20:26:55] <malcom2073> Is the machine *a* wooden structure?
[20:26:59] <MrSunshine> no
[20:27:02] <MrSunshine> its IN a
[20:27:16] <MrSunshine> so its not very stable where it stands =)
[20:27:38] <MrSunshine> tho i got to thinking if the Z axis bearings need some new grease .. havent greased them in a year and a half :P
[20:27:49] <MrSunshine> pits to put grease in tho
[20:29:05] <XXCoder> I would be amazed if someone made engine out of wood and it works and car can go 60 mph
[20:29:25] <XXCoder> (besides impossible to make in wood sparkj plugs, wires so on)
[20:36:21] <MrSunshine> sucks .. i want to upgrade the machine but its frekkin expensive to do :/
[20:36:30] <MrSunshine> all the money i earn has to go for food :/
[20:37:30] <MrSunshine> hoping to sell these this weekend tho =)

[20:48:55] <JT-Shop> nice sign
[20:57:11] <furrywolf> overall, this project wasn't that bad. all of the annoyances was due to my doing it with the radiator still in, with ~3" of clearance between the end of the crank and the radiator, but it still wasn't too bad.
[20:57:42] <furrywolf> still one of the easiest front main seals I've done.
[20:58:12] <furrywolf> I used the crank bolt to install the new seal, as there wasn't enough room for any significant impact to drive it. (I tried)
[20:58:45] <furrywolf> a roll of electrical tape and a large washer. :)
[21:00:17] <furrywolf> next task is to soak the engine and hood in a couple cans of engine brite... in the last week since the seal started leaking, I went from a nice clean engine bay, to everything covered in fresh motor oil.
