[05:41:44] <pcw_home> wow big earthquake in Norcal
[06:18:06] <jthornton> wow M6.0
[06:19:02] <jthornton> http://earthquake.usgs.gov/earthquakes/eventpage/nc72282711#shakemap
[06:24:29] <SpeedEvil> Not completely uncommon for them
[06:25:26] <SpeedEvil> In that there's been a bigger one this year
[06:25:52] <SpeedEvil> And 3 over 4.1
[06:33:14] <jthornton> I live close to the New Madrid Seismic Zone http://upload.wikimedia.org/wikipedia/commons/9/95/New_Madrid_and_Wabash_seizmic_zones-USGS.png but it is not very active
[06:56:31] <SpeedEvil> There has been a bigger already this year in california
[07:58:37] * JT-Shop hopes to get the plasma back together today so I can start back on the dozer 6-way joy stick
[08:16:56] <Tom_itx> we've been getting alot more quakes around here last couple years
[08:20:41] <Tom_itx> mostly felt from Ok.
[09:31:42] <XXCoder> Tom_itx: land is rinising at calfornina so its releasing lot of stresses
[09:31:53] <XXCoder> because water is so goddamn low there
[09:32:13] <XXCoder> https://imgur.com/a/IgoUq
[09:34:36] <CaptHindsight> so the devil (or demons) are using water (or lack of it) to cause the earthquakes?
[09:34:48] <XXCoder> lol
[09:35:05] <Jymmm> It's all bullshit... Someone just pulled the bathtub plug is all
[09:35:49] <XXCoder> Well someone better plug it in soon. calfornia needs it done soon. Know what is ironic? calformia is still bottling and shipping out lot water
[09:36:33] <Jymmm> maybe the onyly water left
[09:36:40] <XXCoder> Capt seriously it's due to weight changes. Water weight is MUCH less now. enough to affect things there
[09:37:14] <Jymmm> Buy your Arizona beach front property now
[09:37:40] <XXCoder> lol calfornia falling into sea is one whig whopper of myth
[09:38:00] <Jymmm> Not falling, breaking off into Island California
[09:39:34] <XXCoder> well land stresses is wrong for that.
[09:40:41] <PetefromTn_> Good Morning People!
[09:40:50] <XXCoder> morning
[09:41:27] <PetefromTn_> so Cali is gonna break off into the Pacific then LOL?
[09:48:33] <XXCoder> http://pubs.usgs.gov/gip/dynamic/graphics/Fig25.gif pete
[09:48:50] <XXCoder> its possible but not for very long time.
[09:50:14] <PetefromTn_> seems like with all the water gone and all the fat people out in San Fran it would just snap off like a potato chip corner in guacamole LOL
[09:52:09] <XXCoder> what if water was only thing holding california on earth ;)
[09:52:42] <PetefromTn_> Well the guys on the airgun forum gave me a new product idea last night. I started making a 3d model of it last night. I am going to try to nail down a design and prototype one here soon hopefully.
[09:53:42] <PetefromTn_> My wife is from there and I used to live there when I was in the United States Coast Guard. She saw the pictures of the damns and bridges all dried up and could not believe it.
[09:53:56] <PetefromTn_> She used to go boating and jet skiing in those lakes as a youth.
[09:54:23] <SpeedEvil> PetefromTn_: are you aware of sailing hydroplanes?
[09:54:30] <XXCoder> yeah when I saw pictures I was stunned
[09:54:47] <SpeedEvil> https://www.youtube.com/watch?v=1SN1gSkqvy0
[09:54:52] <PetefromTn_> you mean those flying hovercrafts?
[09:54:59] <SpeedEvil> no
[09:55:13] <PetefromTn_> Oh sorry you mean a sailboat with hydrofoils
[09:55:24] <SpeedEvil> Well - taken to the minimum
[09:56:12] <PetefromTn_> yeah they are called Moths I think.
[09:56:24] <PetefromTn_> kickass but I am sure NOT too easy to learn to sail on.
[09:56:27] <XXCoder> pretty cool
[09:56:59] <SpeedEvil> I am betting you'd get a leetle bit wet learning, yeah
[09:57:24] <PetefromTn_> https://www.youtube.com/watch?v=GQ-gdqo35os this is amazing..
[09:58:04] <XXCoder> lower cross section in water the better
[09:58:30] <PetefromTn_> sure... 53 MPH huge sailing yacht with no fuel spent. AWesome.
[09:59:02] <XXCoder> yeah carry alternates though wouldnt want to be stuck in becalmed seas
[09:59:28] <PetefromTn_> meh folks have been sailing around the world in less for eons.
[09:59:43] <XXCoder> yeah learning trade winds yeah
[10:00:27] <PetefromTn_> recently watched a video on netfix about a young girl who sailed around the world by herself at like 18 years old. Was quite interesting.
[10:00:47] <XXCoder> heard of that. I wonder what challenges was
[10:04:10] <Jymmm> Reed Switches https://www.youtube.com/watch?feature=player_embedded&v=FhUt7VyMKT4
[10:04:42] <XXCoder> I hate video suggestions its annoying]
[10:04:59] <Jymmm> then just /ignore me
[10:05:07] <XXCoder> uh
[10:05:12] <XXCoder> not YOUR suggestion
[10:05:15] <XXCoder> in youtube
[10:05:34] <Jymmm> Install YouTube Center
[10:06:57] <XXCoder> lemme check that when done
[10:08:20] <Jymmm> They have LATCHING reed switches. Hmmm
[10:12:17] <XXCoder> okay pretty cool
[10:12:23] <XXCoder> but whats reed switches for'
[10:12:46] <Jymmm> magnetic switch
[10:13:08] <PetefromTn_> https://www.youtube.com/watch?v=2cUht1rxnh4 haulin' sail LOL
[10:13:11] <XXCoder> so it turns on in magnetic field
[10:13:34] <Jymmm> correct, but they also have SPDT and NC too
[10:13:49] <XXCoder> and whats those
[10:14:30] <Jymmm> SPDT? Like an A/B Switch
[10:15:04] <Jymmm> LATCHING is magnet near = on, remove magnet, stays on.
[10:19:30] <XXCoder> cool
[11:02:39] <Tom_itx> will this Ca breakoff happen during an election year?
[11:02:58] <XXCoder> yeah at 10201831th election year
[11:44:19] <Tom_itx> JT-Shop, how many miles were on the plugs you replaced in your vehicle?
[11:44:29] <Tom_itx> i'm thinking it may be about time...
[12:29:31] <JT-Shop> 80k
[12:29:37] <Tom_itx> heh
[12:29:44] <Tom_itx> i just hit ~80k :D
[12:30:10] <Tom_itx> seems a bit down on power
[12:31:28] <JT-Shop> NGK's Laser Iridium plugs typically last 80-100k miles.
[12:31:41] <XXCoder> laser lol
[12:31:46] <JT-Shop> my OEM plugs were that type
[12:32:06] <XXCoder> I bet when we has hyperspace engines there would be laser hyperspace iridium plugs
[12:33:00] <Tom_itx> these are delco Iridium
[12:33:03] <XXCoder> companies love to use cool sounding words. Like titanium shaving when it contains no atom of titanium
[12:42:36] <pcw_home> almost everything contains at least a few atoms of Titanium :-)
[12:42:56] <XXCoder> fine. less than mole of titaniuum then! more scienfic! lol
[12:43:26] <jdh> how about a mole of moles.
[12:43:31] <XXCoder> xkcd
[12:44:08] <XXCoder> just checked out youtube center
[12:44:09] <XXCoder> nice
[12:52:44] <james628> I have bad (unusable) latency figures with LinuxCNC 2.6 (form hybrid ISO image) while very good latency with 2.5 LCNC (ubuntu 10.04) on the same machine (HP d530) . What would you recommend?
[12:54:51] <somenewguy> aftermarket iridium plugs and OEM plugs are not the same
[12:55:34] <JT-Shop> james, what are you asking?
[12:56:35] <JT-Shop> james628, ^^^
[12:57:27] <james628> I am asking if I can use safely the new 2.6 with those bad latency times, or should I install the older version
[12:58:29] <JT-Shop> well if the latency is bad don't use Debian use 10.04 Ubuntu
[12:59:47] <onyedikilo_> i am loosing steps, any good ways to test for emi ?
[13:01:06] <JT-Shop> james628, you can run 2.6 on Ubuntu 10.04 http://wiki.linuxcnc.org/cgi-bin/wiki.pl?UpdatingTo2.6
[13:02:35] <archivist> onyedikilo_, does the step loss change with spindle motor (vfd noise)
[13:03:09] <onyedikilo_> nope, i could not verify it, sometimes looses steps
[13:03:14] <james628> JT, yes, I know, but it's a fresh install, so I wanted to use newer system. It's pity that 3.4.9 RTAI kernel performs not soo good. may Xenomai kernel help?
[13:03:24] <onyedikilo_> it wont matter if the vfd is on or off
[13:03:26] <JT-Shop> onyedikilo_, did you do a stepper test?
[13:03:28] <archivist> onyedikilo_, type of stepper driver?
[13:03:37] <onyedikilo_> leadshine dm870
[13:03:45] <JT-Shop> james628, that is beyond my guesspertice
[13:03:55] <onyedikilo_> JT-Shop what is a stepper test ?
[13:04:24] <JT-Shop> it's in the manual http://linuxcnc.org/docs/html/common/Stepper_Diagnostics.html
[13:04:31] <archivist> I have has a VDF affect the leadshine stepper driver when not driven very well and a poor ground to the motor
[13:06:30] <onyedikilo_> JT-Shop, yes i tested with linear movements, the problem arises when i use 3 axis at the same time, all of the test i have done so far with linear motion passed.
[13:07:27] <JT-Shop> could be not enough power to keep the voltage up when running all three axes
[13:07:56] <onyedikilo_> JT-Shop, I have 4 motors and 4 seperate power supplys for each motor.
[13:08:18] <XXCoder> house not supplying enough power?
[13:08:41] <onyedikilo_> well i never thought of that
[13:08:59] <onyedikilo_> but each one is around 600 watts
[13:09:01] <XXCoder> dunno how test that
[13:09:35] <onyedikilo_> 2.4 kw + 2.4 for the spindle and 1 kw for other stuff. i believe it is not that much
[13:11:07] <onyedikilo_> also on circular moves with g3 i sometimes hear a bang, i slowed down the machine but the bang is there :/
[13:11:33] <onyedikilo_> it is like it is hitting something
[13:12:36] <onyedikilo_> first i thought i was having step losses with z axis only but later i realized i am having it on all the axis
[13:13:00] <onyedikilo_> i slowed down the machines velocity anc acceleration
[13:13:45] <onyedikilo_> it improved the cut
[13:14:22] <onyedikilo_> then i tri┼čed a long g-code around 500k lines, hoping that it wons miss any steps, but the result was the same
[13:14:44] <onyedikilo_> i am thinking about emi
[13:15:05] <XXCoder> whats room like?
[13:15:15] <XXCoder> any wires running near forsecent lights?
[13:15:16] <onyedikilo_> all my cables are shielded except the dc power supply cables and some short cables inside the controller box
[13:15:31] <pcw_home> are all step/dir lines routed away from power/motor wires?
[13:15:42] <onyedikilo_> room doesnt have any lights , i just put a light bulb
[13:16:15] <onyedikilo_> let me get some pictures or a video and show you guyz how it is wired.
[13:16:37] <XXCoder> cfl light bulbs has minor emf, but not very strong, few feet hould isolate it just fine
[13:19:18] <XXCoder> "What about CFLs specifically? They do indeed put out more EMF in certain frequencies than incandescent or halogen bulbs, but there is no evidence that this level of EMF poses any health consequences. Further, one thing is absolutely clear ľ EMF falls off sharply with distance. Even after a couple of feet the EMF put out by light bulbs falls from tiny by many orders of magnitude to negligible. "
[13:19:38] <XXCoder> so hmm
[13:19:53] <XXCoder> you probably should check that sound when it makes circle
[13:20:00] <pcw_home> Like archivist said, weak step/dir drive is also a possibility
[13:20:00] <XXCoder> it may be actually hitting something
[13:21:30] <archivist> a step loss is often a clonk sound
[13:21:45] <archivist> or a duff coupling
[13:22:45] <onyedikilo_> i got the pictures, where can i share them?
[13:26:00] <JT-Shop> imagebin.org
[13:26:25] <onyedikilo_> ok here is the controller cabin http://tinypic.com/r/adybo9/8
[13:26:46] <onyedikilo_> could it be that the cables are all over the place ?
[13:28:26] <onyedikilo_> this is the cables and how they travel http://tinypic.com/r/2jeqzgh/8
[13:30:04] <onyedikilo_> this is the spindle and vfd connection http://tinypic.com/r/k6r05/8
[13:30:20] <zbychuk> Hi, I have d2700mud motherboard and I got 35us Max Jitter for Base thread on it.
[13:31:08] <zbychuk> when i tried a PCI graphics card on this board Max Jitter grown to 65us. Why?
[13:31:33] <zbychuk> Can abyone tell me?
[13:31:54] <zbychuk> I only performet Latecy test
[13:32:09] <zbychuk> i dont have any CNC machine yet
[13:33:14] <onyedikilo_> maybe the built in gfx card has a faster comm, or maybe the pci gfx driver is causing the problem?
[13:34:07] <onyedikilo_> probably the pci card put and extra stress on the machine
[13:39:08] <pcw_home> Probably block transfers to/from PCI stop everything (the built in video is probably much faster ad data transfers)
[13:41:45] <XXCoder> http://www.instructables.com/id/C-Clamps-Bah-25-Other-Clamps-They-Dont-Want-You-To/ interesting
[13:44:19] <zbychuk> Thanks
[13:45:07] <pcw_home> onyedikilo_: I would route the step/dir lines so they do not run parallel to any motor or power wiring
[13:45:50] <onyedikilo_> you mean, inside the panel?
[13:45:56] <pcw_home> Yes
[13:46:06] <pcw_home> well everywhere
[13:46:13] <onyedikilo_> yeah it sure is a mess right now
[13:46:48] <XXCoder> LOL just saw I clamp in that link I just linked here. I wonder how THAT will ever be used :P
[13:46:59] <pcw_home> note that shielded cable do very little to protect against magnetic coupling
[13:47:14] <pcw_home> s/do/does/
[13:47:25] <onyedikilo_> is there a way to know for sure that there is an emi problem
[13:48:11] <pcw_home> if better cable routing fixes it :-)
[13:48:21] <onyedikilo_> :)
[13:48:58] <onyedikilo_> i will change the enclosure tomorrow and put a fan to cool the drivers
[13:49:05] <onyedikilo_> rewire everything
[13:49:29] <onyedikilo_> should i use shielded cables for the dc power supply?
[13:50:26] <pcw_home> No but I would make sure that any power wires are routed away from step/dir wires
[13:51:27] <onyedikilo_> can i use ethernet cable for wiring inside the control box? i could not find a twisted pair wire with a shield
[13:51:51] <onyedikilo_> or just shielded wire will do ?
[13:52:16] <onyedikilo_> i am asking this for the cables running from the driver to the bob
[13:52:29] <onyedikilo_> right now they are unshielded
[13:52:47] <onyedikilo_> but the driver to motor wires are shielded and grounded
[13:53:56] <pcw_home> you could shield the step/dir wires but routing is more important
[13:54:35] <onyedikilo_> any example diagram or picture for a similar routing ?
[13:56:24] <pcw_home> basically its simple, keep the power wiring away from the low level signals
[13:57:29] <onyedikilo_> but at the end they are real close when connected to driver.
[13:57:52] <onyedikilo_> keeping the rest away will be ok i guess
[13:58:36] <onyedikilo_> one more thing,the driver i have is configured for the step and dir signals to use rising edge, this means it is active high right?
[13:59:00] <pcw_home> probably...
[13:59:45] <onyedikilo_> probably ? :)
[14:00:54] <somenewguy> USB cable has a shield, you could cut that up?
[14:01:05] <somenewguy> depending on how much length you need of course
[14:01:28] <somenewguy> you never konw when you have an EMI problem, you just have a problem you can't blame on anything else lol
[14:01:38] <onyedikilo_> lol
[14:01:52] <onyedikilo_> wouldnt a cat5 cable be better ?
[14:01:58] <somenewguy> a fun pointer I learned when I was playing w/ CB radio, is never coil up extra wire, you are just making a good antennna
[14:02:19] <somenewguy> loop it back and forth in a S shape to waste extra length, so that it is going in the opposite direction each time and some of hte noise will cancel out
[14:02:30] <somenewguy> USB is twisted pair plus a heavy shield or foil
[14:02:51] <somenewguy> Cat5 shield costs extra
[14:03:22] <onyedikilo_> i got some long usb cables lying around
[14:03:36] <onyedikilo_> usb2.0
[14:03:37] <somenewguy> I have no idea what you are using the cable for, but good luck
[14:03:56] <onyedikilo_> i will use it for the connection between breakout board and the driver
[14:04:07] <somenewguy> I have no clue what the charactaristic impedence of USB is either, but it is super cheap
[14:04:35] <somenewguy> USB is usually 2 twisted pair, mini and micro have a 5th wire, plus shield
[14:04:58] <somenewguy> USB3 is 9-11 conductor plus shield, but I don't know how expensive it is
[14:05:48] <somenewguy> and if you wanna get really fancy you can alsways buy those clip on ferrites, i have no idea if they help or not, but they can't really hurt
[14:06:20] <onyedikilo_> yeah i was just looking for a supplyer for those ferrite beads
[14:06:23] <somenewguy> EMI is one of those things I always just throw as many solutions at that I can afford, since it is so dang hard to fix
[14:06:39] <somenewguy> mouser, digikey, newark etc should have em
[14:06:46] <somenewguy> the trick is knowing what they are called by the "pros"
[14:06:55] <onyedikilo_> i am in Istanbul
[14:07:17] <onyedikilo_> yes they have funny names 'n here too
[14:07:18] <somenewguy> doesn't farnell have a international branch? do they ship your way
[14:07:58] <somenewguy> alternatly scavenge them off old electronics
[14:08:07] <onyedikilo_> yes they probably would ship but i better find someone close so i can go and buy them tomorrow
[14:08:19] <somenewguy> you can shave the rubber off w/ a razor and liberate them once you cut the end offf the wire
[14:08:35] <onyedikilo_> i can buy vga cables and remove the ferrites
[14:08:58] <onyedikilo_> but there is a supplyer nearby most probably
[15:21:50] <JT-Shop> I'm a bit uneasy about rigid tapping M3 x 0.5
[15:39:01] <cpresser> how much holes?
[15:39:16] <cpresser> if its less than 10, i would do them by hand :)
[15:40:37] <cpresser> I have done a lot of those in acrylic, but never in steel.
[15:42:21] <JT-Shop> 10 holes but I can only find a Sears tap in M3 x 0.5 so by hand it is
[15:44:18] <syyl> Undi am more likely to break a m3 by hand than with a machine :D
[15:46:15] <JT-Shop> if I had a good tap I'd do them in the VMC
[15:46:29] <cradek> isn't that about like 4-40? I have done a zillion of those, both cut and form
[15:46:47] <cradek> oh sears, ouch.
[15:47:05] <syyl> is sears something like horrible freight?
[15:47:12] <JT-Shop> yea, they are really old taps
[15:47:52] <JT-Shop> back when I bought them steel came from Pittsburgh and men were men and sheep were scared
[15:48:10] <syyl> :D
[15:48:36] <Jymmm> "When the Men were Men, and the Women were too!"
[15:48:57] <JT-Shop> looking at the cutting edges under the scope and no way I'll try and machine tap with that one
[15:49:05] <syyl> manly men?
[16:03:59] <Deejay> gn8
[16:22:42] <zeeshan> i'm a very happy person right now
[16:22:56] <zeeshan> i repaired 3 different indicators
[16:23:54] <zeeshan> they're not that bad to fix once you figure out the inner workings
[16:24:45] <zeeshan> mine just needed the springs replaces caused they had lost tension
[16:36:41] * JT-Shop pops the top on a cold one and gets the M3 tap out http://www.gnipsel.com/images/plasma/Torch%20Back%20Plate.jpg
[16:39:06] * Tom_itx got plugs to change later in the week
[16:39:54] <Tom_itx> JT-Shop did you use your pocket routine for that?
[16:42:35] <JT-Shop> aye

[17:00:53] <XXCoder> theres other way
[17:01:05] <XXCoder> a false sticker keyboard on top of real one

[20:08:06] <zeeshan> fun stuff.
[20:08:09] <Tom_itx> ok but why not just get what you need to start with?
[20:33:18] <PetefromTn_andro> Evening everyone..
[20:53:54] <zeeshan> hi PetefromTn_andro
[20:53:56] <zeeshan> what are you upto
[20:54:41] <PetefromTn_andro> Right now just chilling out enjoying some music til I fall asleep you?
[20:54:58] <zeeshan> hah
[20:55:01] <zeeshan> im eating too
[20:55:04] <zeeshan> planning to watch a movie
[20:55:11] <zeeshan> spent most of the afternoon pulling the engine out of the rx7
[20:55:25] <zeeshan> i've noticed as i get older, i don't enjoy working on cars as much
[20:55:35] <zeeshan> i dont get the satification i used to get back in the day
[20:55:40] <zeeshan> i get more satisfying from machining something
[20:56:14] <PetefromTn_andro> I found out the 5/16 champfered holes I machined into the prototype rail is the wrong size dammit lol
[20:56:36] <zeeshan> what are they
[20:57:14] <PetefromTn_andro> Well the holes were made to match another rail made by someone else the customer did not like
[20:57:23] <zeeshan> http://imgur.com/a/aZ3Qz
[20:57:34] <zeeshan> bigger im assuming?
[20:57:47] <PetefromTn_andro> I ASSUMED they were 8-32 but they are actually m4
[20:58:34] <PetefromTn_andro> So when I went to order the screws from McMaster Carr realized the heads are slightly larger
[20:58:34] <jdh> Pete: http://www.ebay.com/itm/290772919340
[20:59:06] <zeeshan> 8-32 calls for .136 drill (#29)
[20:59:25] <zeeshan> m4x.7 calls for .1299
[20:59:27] <zeeshan> 3.3 mm drill
[20:59:29] <PetefromTn_andro> Yeah the holes are drilling and tapped correctly
[20:59:37] <zeeshan> oh
[20:59:52] <PetefromTn_andro> But the champfer for the countersink head is wrong
[21:00:11] <jdh> 83?
[21:00:35] <PetefromTn_andro> They are gonna be 8-32 but now I gotta machined the champfer different
[21:01:28] <PetefromTn_andro> Sae 8-32 is 82 degree and the head is larger
[21:02:02] <PetefromTn_andro> Larger than the 5/16 countersink I have.
[21:02:10] <jdh> off by a degree
[21:02:45] <PetefromTn_andro> I am just gonna do it manually with my drilling and 82 degree cs
[21:02:57] <jdh> metric is 90. much more reasonable number.
[21:03:02] <jdh> well, not number, but angle.
[21:03:03] <PetefromTn_andro> Drill
[21:03:18] <PetefromTn_andro> Agreed
[21:03:37] <jdh> it's a stupid number
[21:03:50] <PetefromTn_andro> It sucks because my holes came out perfect when I machined them.
[21:04:05] <jdh> for the sake of perfection,you should start over.
[21:04:51] <PetefromTn_andro> Now I gotta try to fix this one manually. It's just a prototype so I guess it's okay. Heads will just be .050 or so larger.
[21:05:29] <PetefromTn_andro> If I sell a bunch I will just order th e
[21:05:46] <PetefromTn_andro> Right screws and countersinks
[21:07:09] <PetefromTn_andro> Other than that it looks awesome and fits perfectly to the original receiver lines.
[21:09:42] <PetefromTn_andro> I sure hope people like them it would be nice to get a bunch of orders for em LOL
[21:14:11] <PetefromTn_andro> Have you made anything cool on your cnc lathe zeeshan?
[21:16:06] <zeeshan> just those an fittings
[21:16:35] <zeeshan> https://www.youtube.com/watch?v=8yl26NbBBaM
[21:16:39] <zeeshan> kinda busy with the car right now
[21:16:40] <zeeshan> :P
[21:17:48] <zeeshan> i wish i had a cnc mill right now
[21:17:52] <zeeshan> i want to machine some stainless flanges
[21:18:45] <PetefromTn_andro> Did you actually machine them or just simulate
[21:19:08] <zeeshan> i machiend them
[21:19:10] <zeeshan> no video though
[21:19:46] <PetefromTn_andro> Aah Don't you have your knee mill to make the flanges?
[21:20:15] <zeeshan> yes
[21:20:21] <zeeshan> but they've got some fancy contours
[21:20:41] <zeeshan> http://www.turbo-flanges.com/images/LS1.jpg?osCsid=d10477663280da3ba0f1fa932063ed24
[21:20:44] <PetefromTn_andro> Uh oh
[21:21:14] <PetefromTn_andro> Exhaust flanges
[21:21:18] <zeeshan> yessir
[21:21:33] <PetefromTn_andro> Those looks pretty nice
[21:21:41] <PetefromTn_andro> Look
[21:21:48] <Tom_itx> mmm those look familiar :D
[21:21:58] <Tom_itx> i did a similar set for my bud once
[21:23:28] <PetefromTn_andro> Can you make them on the machines at school you use
[21:24:55] <zeeshan> yea
[21:25:02] <zeeshan> but they'll get pissed when they know what they are
[21:25:03] <zeeshan> lol
[21:25:19] <zeeshan> i think ill just get them water jet cut
[21:25:24] <zeeshan> and then mill the recess on the mill
[21:26:19] <PetefromTn_andro> PINK FLOYD - KEEP TALKING [ HQ ]: http://youtu.be/aFZxm09G87E. Love this song...
[21:27:16] <zeeshan> youre old school :D
[21:27:30] <PetefromTn_andro> I did not like the waterjet we used at the shop I worked in. Nasty dirty machine
[21:27:31] <zeeshan> do you like metallica?
[21:27:47] <PetefromTn_andro> Meh they're okay.
[21:28:33] <PetefromTn_andro> Funny thing is it may be old school but I just got this album for my birthday a couple weeks ago
[21:28:55] <PetefromTn_andro> Never heard any of these songs before.
[21:29:01] <Tom_itx> dark side of the moon is good
[21:29:15] <PetefromTn_andro> Yeah I have about Ll
[21:29:30] <PetefromTn_andro> All their albums over the years.
[21:30:07] <PetefromTn_andro> I think it's cool how they put Steve hawkings computer voice in that track
[21:32:30] <PetefromTn_andro> Just out of curiosity what was your machining strategy for making those flanges Tom?
[21:32:57] <Tom_itx> it was a long time ago
[21:33:13] <Tom_itx> i think i probably drilled a couple holes to clamp then profiled em
[21:33:27] <Tom_itx> at least that's what i'd do now
[21:33:45] <Tom_itx> maybe 3 or 4 bolts
[21:34:19] <PetefromTn_andro> So screws down to substrate and profile after clamping and drilling
[21:34:45] <Tom_itx> predrill/tap the sacrificial plate
[21:34:53] <Tom_itx> drill the holes
[21:34:57] <PetefromTn_andro> Sure
[21:35:02] <Tom_itx> and mill away
[21:35:14] <PetefromTn_andro> Simple really
[21:35:20] <Tom_itx> 3 would probably be enough
[21:35:23] <Tom_itx> bolts
[21:35:39] <jdh> I have some 0.010" plastic shim material I've used to keep the work off the sacrificial plate. Used the same plate lots of times.
[21:36:00] <Tom_itx> after while we'd just skin cut the plate
[21:36:01] <PetefromTn_andro> I'd probably do more for stainless but I am a pain in the ass LOL
[21:36:40] <PetefromTn_andro> Yeah I have a couple plates here used for stuff like that.
[21:37:12] <PetefromTn_andro> One was for that custom battery tray prototype I made for those guys.
[21:37:55] <PetefromTn_andro> Unfortunately I think they advertised them and jacked the price too high for any real interest to be garnered
[21:37:58] <Tom_itx> we're lucky enough to have plenty of scrap in town
[21:38:11] <Tom_itx> can get nearly any size plate we'd need
[21:38:58] <PetefromTn_andro> Apparently there are some good scrap metal places in knoxvegas but never been there yet
[21:39:54] <PetefromTn_andro> Started working on another design for the shooting competition guys yesterday Ajax
[21:40:15] <PetefromTn_andro> Had a bunch of guys request this part to be made.
[21:40:47] <PetefromTn_andro> Probably hear crickets once I make one and have them ready to sell hehe
[21:41:18] <Tom_itx> just say 'show me the money'
[21:41:22] <Tom_itx> then make em
[21:42:33] <PetefromTn_andro> Yeah I know but honestly most of those guys rarely bullshit me about things generally if they ask for it as long as the price is right they Wil l
[21:42:41] <PetefromTn_andro> Will buy it
[21:43:06] <Tom_itx> hardly worth making just one or two though
[21:43:31] <PetefromTn_andro> Those guys spend more money on precision air rifles than I spend on my house
[21:43:32] <Tom_itx> how many machine hours are in them?
[21:43:40] <Tom_itx> + setup time
[21:43:44] <Tom_itx> + programming time
[21:44:08] <PetefromTn_andro> Oh there's already like ten guys committed to ordering one or two
[21:45:02] <PetefromTn_andro> Right now I don't really have anything else worth talking about going on so I guess I will make them.
[21:45:27] <PetefromTn_andro> I could use one myself too lol
[21:46:16] <PetefromTn_andro> It has been hot and humid as he'll here all weekend
[21:46:27] <PetefromTn_andro> Hell
[21:47:31] <PetefromTn_andro> Well better get to sleep cya later guys.
