[00:00:00] <Jymmm> gotcha =)
[00:00:06] <XXCoder> yeah
[00:00:36] <Jymmm> XXCoder: Well, now you can scrap the other car for $500
[00:00:52] <XXCoder> think so yes
[00:00:54] <Jymmm> XXCoder: or sell it not running, as is, for parts, for $800
[00:01:07] <XXCoder> yeah plan do that first
[00:01:25] <Jymmm> Hell, ask $1800
[00:16:33] <zeeshan|2> man
[00:16:41] <zeeshan|2> the problem was i was tracking the WRONG point on the insert
[00:16:42] <zeeshan|2> lol
[01:39:27] <tjtr33> nice puma running under linuxcnc http://westcoastmakers.com/threads/arm-o-matic.78/
[01:39:36] <tjtr33> west coast of OZ i think
[02:11:30] <Deejay> moin
[02:29:22] <zeeshan|2> http://i.imgur.com/wvdhjOG.jpg
[02:29:25] * zeeshan|2 loves cnc
[02:29:28] <zeeshan|2> die made in 5 minutes
[02:35:08] <RyanS> Whatever you have made in five minutes... I hate you. :)
[02:35:23] <zeeshan|2> i was making this die wrong first
[02:35:28] <zeeshan|2> i had the sfm set to 75 rpm
[02:35:29] <zeeshan|2> er
[02:35:31] <zeeshan|2> 75 fpm
[02:35:35] <zeeshan|2> was wayyy too slow for carbide
[02:35:46] <zeeshan|2> shot it up to 200
[03:26:30] <Loetmichel> mornin'
[03:30:43] * Loetmichel just has slitted is middlefinger with an xacto knife. Note to self: No difficult tinkering before the first coffee... *clean the bloddy mess* *but a bandaid on* *GET A COFFEE*
[04:19:57] <RyanS> Is it really necessary to splash coolant around like this http://www.youtube.com/watch?v=DGfRh1uEcVo
[04:20:28] <RyanS> It's not like it's an industrial machine which requires high-pressure coolant or something
[04:21:37] <somebub> any good 2 d clipart that is like parts ? free open sourced or public domain . sprockets and other parts every time i look sites say free but want money
[05:04:12] <Jymmm> somebub: http://openclipart.org/
[05:09:48] <somebub> thanks li look.
[05:25:56] <Jymmm> somebub: http://arc.id.au/GearDrawing.html

[05:59:04] <Valen> RyanS: doesnt look like a duck call ;-P
[05:59:15] <Valen> lol i like the brush
[05:59:49] <RyanS> I know I couldn't stop laughing when I saw the paintbrush
[06:00:31] <RyanS> I can't see that cleaning method taking off in the manufacturing industry :P
[06:00:51] <Jymmm> Do you realize how much of a PITA it is to get acrlyic swarf off with all that static build up?!
[06:01:05] <Jymmm> less hosing it off
[06:02:05] <RyanS> would still have static with the brush
[06:02:18] <Jymmm> but it'll at least collect it
[06:03:07] <RyanS> http://www.youtube.com/watch?v=jxWbz0Wf2rM this is awesome
[06:03:30] <Jymmm> that shit just sticks worse than your ex wife wanting alimony =)
[06:04:10] <RyanS> Can't relate it is unwise to get married
[06:05:37] <Jymmm> See al the swarf in the dome video? that hit just doens't come off no matter what!
[06:06:55] <Jymmm> talk about no tool marks! damn!
[06:08:39] <Loetmichel> RyanS: hmm,. cant say that
[06:08:53] <Loetmichel> <- happily married for 14 years now ;-)
[06:09:28] <Jymmm> Loetmichel: And how many hundreds of miles away does she live?
[06:12:04] <Loetmichel> a few meteres?
[06:13:02] <Jymmm> Loetmichel: ok, just checking =)
[06:32:07] <Loetmichel> *ups*... just have charged an 18650 cell to 4.34V... shitty bench power supply drifting with temperature... i doubt i should put that cell back in my pocket ;-)
[06:42:16] <Jymmm> Loetmichel: Just make sure your keys are in your pocket too
[06:42:33] <Jymmm> Loetmichel: is it hot?
[06:43:50] <Loetmichel> ice cold
[06:44:07] <Jymmm> discharge it to 4.2 then
[06:46:19] <Loetmichel> already did
[06:47:28] <Jymmm> should be ok then, no?
[06:48:01] <Jymmm> Loetmichel: how fast did you charge it?
[06:48:45] <Loetmichel> 1C
[06:48:52] <Loetmichel> 2.8A
[06:48:56] <Loetmichel> current limited
[06:49:14] <Jymmm> Ah, so fairly fast. I have a slow charger, takes a few hours
[06:49:26] <Jymmm> .5a
[06:49:53] <Jymmm> and all my cells are protected
[06:49:54] <Loetmichel> <- was to wimp to turn the psu up to full 6A ;-)
[06:50:02] <Jymmm> lol
[06:50:19] <Jymmm> Not a wimp when it comes to explosive devices =)
[06:50:44] <Jymmm> flying burning lithium is not a good thing
[06:51:33] <Loetmichel> i am model pilot
[06:51:51] <Loetmichel> you dont want to know how i torture the flight battery packs
[06:51:56] <Loetmichel> :-)
[06:52:06] <Loetmichel> and they re lipo7lifepo4, too ;-)
[06:52:14] <Loetmichel> -7+7
[06:52:16] <Jymmm> 18650 for plane?
[06:52:19] <Loetmichel> grrr
[06:52:21] <Jymmm> plane
[06:52:32] <Loetmichel> no, the 18650 is for my e-cig/my flashlight
[06:52:40] <Loetmichel> -7+/
[06:52:44] <Loetmichel> now its right ;-)
[06:52:47] <Jymmm> eCig/flashlight?! damn!
[06:53:08] <Jymmm> Gives new meaning to the term "torch"
[06:53:17] <Loetmichel> not one part
[06:53:21] <Loetmichel> twio parts
[06:53:29] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14733
[06:53:31] <Jymmm> I know, but mine was funnier =)
[06:53:41] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14996
[06:54:02] <Loetmichel> ... nontheless i MADE a flashlight from a spare ecig-battery:
[06:54:08] <Jymmm> Loetmichel: but my flashlight is a charger/pwr source too
[06:54:33] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14748
[06:54:37] <Jymmm> http://www.kaidomain.com/product/details.S022116
[06:54:53] <Jymmm> Uses 1 to 3 18650's
[06:55:08] <Loetmichel> Jymmm: to big for trousers pocet ;:)=
[06:55:24] <Jymmm> Loetmichel: But PERFECT for glove box
[06:55:31] <Jymmm> emergency power too
[06:56:11] <Jymmm> recharges from usb too
[07:04:42] <Valen> ey Loetmichel, mother in law and wifes best friend both smoke and it really messes me up, I was thinking of getting them ecigs
[07:04:44] <Valen> any suggesitons?
[07:09:57] <Loetmichel> i liked my kanger T3s
[07:10:12] <Loetmichel> but since last week i have the cvamo and the protanks
[07:10:25] <Loetmichel> .... no comparsion, different league ;-)
[07:10:35] <Loetmichel> -c
[07:10:54] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14990
[07:11:08] <Loetmichel> T3s: all heads that are plstic in the pic
[07:11:22] <Loetmichel> the batteries differ: the small ones are 650mAh
[07:11:27] <Loetmichel> the bigger are 1000 mah
[07:11:45] <Loetmichel> and the one in the middle is the vamo with an 18650 inside ;-)
[07:12:02] <Jymmm> 18650 in an eCig?! damn
[07:12:20] <Jymmm> frickin eCigar!
[07:12:37] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14996
[07:12:45] <Loetmichel> i have no small hands...
[07:12:47] <Loetmichel> ;-)
[07:12:51] <Jymmm> lol
[07:13:21] <Jymmm> I just wish I could find good eLiquid. Mine hits hard/harsh
[07:13:32] <Jymmm> so I don't use it
[07:14:02] <Loetmichel> i DO have a "few" of the t3s heads andkanger batterys: http://www.cyrom.org/palbum/main.php?g2_itemId=14799
[07:14:03] <Loetmichel> ;-)
[07:15:36] <Valen> where do you buy that stuff from?
[07:16:46] <Loetmichel> www.dampfplanet.de
[07:20:51] <Jymmm> Oh great, DX no longer has eCigs it seems
[07:23:17] <Valen> yeah i saw that
[07:23:24] <Valen> they moved them to some other site it seems
[07:23:34] <Valen> that charges shipping i think
[07:23:56] <Jymmm> same parent company, but yeah, now pay shipping
[07:24:04] <Jymmm> http://www.volumerate.com/search/ego
[07:27:36] <Jymmm> This is the one I have http://www.volumerate.com/product/egot-quit-smoking-usb-rechargeable-electronic-cigarettes-w-5-refills-pair-mb-flavor-111509
[07:29:10] <Loetmichel> Jymmm: hrhr, thats cute ;-)
[07:29:20] <Jymmm> ?
[07:29:25] <Loetmichel> that e-cig
[07:29:32] <Jymmm> what about it?
[07:29:42] <Loetmichel> its the usual "starter" set
[07:29:42] <Jymmm> you get two for $20
[07:29:49] <Loetmichel> and very cute
[07:29:56] <Loetmichel> but not really useabnle
[07:30:02] <Jymmm> Well, not everyone has a belt holster of eCigars =)
[07:30:28] <Loetmichel> i get mayba 10 times the cvape out of the big one and 5 times out of the t3s
[07:31:07] <Jymmm> I'm just not that much into them. If I found a great eLiquid, maybe.
[07:31:49] <Loetmichel> Jymmm: http://www.cyrom.org/palbum/main.php?g2_itemId=14993
[07:31:56] <Loetmichel> ... if you know what i mean ;-)
[07:32:23] <Jymmm> lol, yeah I know.
[07:32:48] <Jymmm> Around these parts, eLiquid is NOT what they are used for =)
[07:32:57] <Jymmm> (not me, but others)
[09:56:18] <jdh> that's a lot of hassle just for a nicotine addiction
[09:57:01] <jdh> unless you are putting better substances in the e-thing, I don't understand their existence.
[09:57:17] <ssi> personally I think they're fantastic, and I don't smoke
[09:57:49] <ssi> I'm horribly allergic to cigarette smoke, but the vaporizors don't bother me in the slightest
[09:57:53] <Loetmichel> jdh: i dont see it as an addiction any more
[09:57:57] <ssi> the filthy addicts get their drugs, and I get to not die
[09:57:58] <Loetmichel> at least not to nicotine
[09:58:22] <Loetmichel> it helpend me to quit smoking
[09:58:24] <Loetmichel> instantly
[09:58:39] <Loetmichel> but now i am vapung for the fun of it
[09:58:46] <ssi> yea
[09:58:51] <ssi> I bought my mom a setup for that reason
[09:59:02] <ssi> and she's weaned down in 2 months from 16mg to 0.4mg juice
[09:59:06] <Loetmichel> 8AND the niocotine, altough i have reduced the N contents since i did qout smoke)
[09:59:26] <CaptHindsight> is there tobacco flavored ecig juice?
[09:59:27] <Loetmichel> i am dwon from 18mg to 11
[09:59:38] <Loetmichel> CaptHindsight. a bunch of it
[09:59:57] <Loetmichel> you can get camtel, danhall, marlbro and so on ;-)
[10:00:13] <CaptHindsight> easy enough to make but too dangerous for the untrained
[10:00:45] <jdh> if you are still vaping nicotine, you are still an addict.
[10:00:51] <CaptHindsight> nicotine poisoning from handling it without gloves
[10:01:20] <Loetmichel> jdh: jeah.
[10:01:25] <CaptHindsight> jdh: did they secure all the ball screw ends the same way for each axis?
[10:01:29] <Loetmichel> dosent bother me at all though
[10:01:54] <jdh> CaptHindsight: Z seems to float in the bearing
[10:02:08] <jdh> X is captured on both sides and in tension
[10:02:59] <jdh> I doubt the Z actually floats much though.
[10:03:13] <jdh> They seem to have doen an incredibly job of removing all excess cost
[10:03:33] <CaptHindsight> heh cutting corners
[10:03:58] <jdh> yeah. even down to asymmetric angle brackets
[10:04:11] <CaptHindsight> that's the problem I've had, having to add those corners back after arrival
[10:04:22] <jdh> I didn't get the table. Just the gantry and electronics
[10:04:52] <jdh> a few pics at: http://tinyurl.com/l5uuv8l
[10:05:29] <jdh> Couldn't tell if they were ACB's. I'd guess they are just plain radial bearings though.
[10:07:09] <Loetmichel> no pic of the assembled machine?
[10:07:23] <jdh> The electronics actually look ok. Only thing I see really missing is the earth from spindle to VFD. I'll probably replace all the VFD wiring with good shielded stuff anyway.
[10:07:37] <jdh> Loetmichel: I only got box 2 of 2. No table
[10:07:44] <Loetmichel> ah
[10:07:45] <Loetmichel> bad
[10:08:23] <jdh> yeah. looks like it will be in Cincinnati shortly but I don't think they will deliver it until monday
[10:09:04] <jdh> Gives me the weekend to remove my old router and clean up some space for teh new one.
[10:09:47] <archivist> might need the old one to make bits for the new
[10:10:06] <jdh> If I ever finished teh wiring on my mill, I could wall mount the electronics box instead of taking up half a bench. My table saw is also currently the computer stand for the mill.
[10:10:31] <jdh> archivist: I'll just use the mill if needed.
[10:10:37] <CaptHindsight> I can't seem to find one that is setup properly right out of the box
[10:10:39] <archivist> I understand the stacking syndrome
[10:10:56] <jdh> heh... anything with horizontal space promptly gets 2 layers of stuff
[10:11:10] <skunkworks> only 2?
[10:11:43] <archivist> I thought 3 layers was a minimum specification
[10:11:45] <jdh> CaptHindSight: I expected it to have as much cost removed as possible at this point. I am fairly impressed with the electronics (never having powered them up)
[10:12:07] <jdh> after 2 layers, it isn't usually horizontal enough for a third.
[10:12:57] <archivist> I can take pics to disprove that theory
[10:13:06] <jdh> The spindle water pump is run off the 24v stepper supply. I'll probably replace that before use.
[10:15:28] <CaptHindsight> http://www.technocnc.com/cnc-router-systems/HD-Mini-series-cnc-router.htm what does Techno charge for these? >$5K?
[10:15:59] <Loetmichel> jdh: thats a good idea, it is loud as heell also
[10:16:54] <jdh> That is a much better looking machine.
[10:17:45] <jdh> any idea how many volts these drivers could take?
[10:18:02] <Loetmichel> 32V is absolute mayx
[10:18:14] <Loetmichel> but only if they havent used some 25V caps
[10:18:22] <jdh> can probably crank the 24v PS up to 28-30.
[10:18:51] <jdh> I think it said 350w.
[10:19:12] <Loetmichel> like this board: http://www.cyrom.org/palbum/main.php?g2_itemId=13412
[10:19:24] <Loetmichel> learned it tha hard way;-)
[10:19:39] <jdh> c'mon, I have MBs that look way worse than that and still run.
[10:20:14] <Loetmichel> ... that have blown fishy juice at you when you were looking at it?
[10:20:17] <jdh> The breakout board didn't look like it had pins for the rest of the available inputs.
[10:20:37] <Loetmichel> fishy scalding hot juice
[10:39:29] <CaptHindsight> http://www.cncrouterparts.com/pro4824-4-x-2-cnc-router-kit-p-250.html for $2.8K! and no titanium framing?
[10:42:03] <jdh> add your own table?
[10:43:16] <ssi> CaptHindsight: their stuff is actually VERY beefy and nice
[10:43:20] <ssi> I've seen it in person
[10:43:56] <ssi> I dunno if it's $2900 nice
[10:45:05] <jdh> much better size than mine
[10:54:12] <SpeedEvil> http://www.ebay.co.uk/itm/MORBIDELLI-AUTHOR-600-CNC-ROUTER-USED-WOODWORKING-MACHINE-/271521452408?pt=UK_BOI_Building_Materials_Supplies_Carpentry_Woodwork_ET&hash=item3f37f09178
[10:54:24] <SpeedEvil> I think, on reflection I want one a leeeetle smaller
[10:56:14] <ssi> SpeedEvil: :D
[10:56:18] <ssi> that's a monster
[10:56:32] <SpeedEvil> 14 spindles...
[10:56:40] <ssi> crazy
[10:56:47] <ssi> I think I want to start buildin a laser soon
[10:57:55] <jdh> yag?
[10:58:06] <ssi> co2
[10:58:15] <ssi> I mean building a laser machine, not the laser itself
[10:58:56] <jdh> will be cool on the sailboat
[10:58:56] <archivist> hmm linuxcnc needs more axes to drive that
[10:59:12] <ssi> yeah I can use bilgewater to cool the tube
[10:59:57] <ssi> hm
[10:59:57] <ssi> http://www.ebay.com/itm/A-set-of-CO2-10600nm-Laser-Head-w-Mirrors-Focus-Focal-Lens-Integrative-Mounts/180872049290?_trksid=p2047675.c100009.m1982&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D23772%26meid%3D8056427366855852833%26pid%3D100009%26prg%3D10164%26rk%3D1%26rkt%3D10%26sd%3D321445743376
[11:00:05] <jdh> we have an old co2 laser with an xy table + z
[11:00:07] <ssi> I don't know much about laser stuff
[11:01:30] <jdh> had a couple of 5kw YAGs but that didn't work out.
[11:08:46] <Smidge204__> pew pew pew
[11:10:40] <PetefromTn_> morning folks..
[11:11:17] <Smidge204__> Just barely
[11:12:19] <jdh> 6 more minutes!
[11:12:20] <ssi> morn pete
[11:12:57] <PetefromTn_> yup..slept in...
[11:13:12] <PetefromTn_> Was up LATE last night reading about custom audio stuff... LOL
[11:13:18] <PetefromTn_> Its a sickness I think...
[11:13:22] <ssi> I bet you were ;)
[11:13:25] <ssi> you figure anything out?
[11:13:36] <PetefromTn_> I dunno man there is so much to learn..
[11:13:45] <PetefromTn_> I am liking the rear loading horns tho..
[11:14:14] <ssi> whatever you decide to do, make sure you're leaning toward efficient fullrange stuff
[11:14:14] <PetefromTn_> I think you are spot on about the 2A3 tube amps tho..
[11:14:29] <ssi> :)
[11:14:46] <ssi> hallelujah, we have another convert
[11:14:47] <ssi> lol
[11:15:13] <archivist> from or to tubes
[11:15:20] <PetefromTn_> we watched a bunch of youtube videos of folks custom builds..
[11:15:28] <jdh> to, obviously.
[11:15:28] <ssi> not so much to tubes, but to the Church of Low Power
[11:15:49] <archivist> to is pure sickness
[11:16:15] <PetefromTn_> I especially like this one.. https://www.youtube.com/watch?v=JbBVZ7T5p3k
[11:16:21] <jdh> you just haven't heard Dr. Dre until you hear it on a tube amp
[11:16:23] <ssi> watch out pete, archivist is gonna measure all your equipment
[11:16:35] <PetefromTn_> bring it on man..;)
[11:17:07] <ssi> PetefromTn_: looks like a good start
[11:17:08] <ssi> http://www.madisoundspeakerstore.com/approx-8-fullrange/fostex-fe206en-8-full-range/
[11:17:10] <PetefromTn_> not the music the setup...
[11:17:23] <ssi> the fostex are excellent drivers, I just prefer the smoother markaudios
[11:18:06] <archivist> this would say I measure :) http://www.collection.archivist.info/searchv13.php?searchstr=electronics+PD
[11:18:07] <PetefromTn_> do they make a comparable markaudio?
[11:18:37] <ssi> alpair 12p is same size I think
[11:18:47] <ssi> but give the fe206 a shot, I'm sure they're very good
[11:18:52] <PetefromTn_> I love the look and sound of the horns like that. I also like the half Chengs look...
[11:18:56] <ssi> the particular fostex drivers I have are shouty, but they're not all that way
[11:19:04] <ssi> the cones on those are made of banana pulp :P
[11:19:30] <PetefromTn_> I think I could so totally build that setup man..
[11:19:42] <ssi> best get on it
[11:19:42] <PetefromTn_> How much did you say you have in your tube amp setup?
[11:19:50] <ssi> maybe $700 each
[11:19:55] <ssi> maybe more, I dunno
[11:20:02] <PetefromTn_> they are dual monos then?
[11:20:18] <ssi> no, two separate stereo amps
[11:20:34] <ssi> I see zero need for monoblocks for the most part
[11:20:40] <PetefromTn_> I showed that video to my wife and she was like...OOH make it so..
[11:20:48] <ssi> the channel separation of the amp is better than the channel separation of a vinyl cartridge
[11:21:19] <PetefromTn_> so one stereo amp for each speaker then. Can you post the pics of your amps again?
[11:21:27] <ssi> um no
[11:21:31] <ssi> one stereo amp for a pair of speakers
[11:21:39] <ssi> I just built two amps and two pairs of speakers
[11:21:45] <mozmck> You really need $30,000 cables to make the amp sound any good you know ;)
[11:21:48] <ssi> and I don't run them at the same time cause I get weird cancellations
[11:21:56] <ssi> mozmck: yeah that's true of anything tho
[11:22:05] <ssi> and you have to replace your house wiring with gold romex
[11:22:18] <mozmck> and a magic disk to set on top of your CD player.
[11:22:26] <PetefromTn_> https://www.youtube.com/watch?v=f9VQeeUhnZ4 this is nice too..
[11:22:34] <ssi> what kind of goddamn animals have CD players anymore
[11:22:46] <mozmck> audiophiles
[11:22:52] <ssi> negative
[11:22:54] <PetefromTn_> how do you get your music into the amps again?
[11:23:06] <ssi> I have a preamp i built
[11:23:10] <Smidge204__> Telepathy
[11:23:14] <PetefromTn_> which one?
[11:23:15] <ssi> plus a phono preamp I built, and a decent turntable
[11:23:18] <ssi> amb.org
[11:23:23] <mozmck> I think it needs to be laser - no wires to interfere.
[11:23:23] <ssi> also built their DAC
[11:23:25] <ssi> y2
[11:23:47] <PetefromTn_> you're my hero man... LOL
[11:24:40] <PetefromTn_> I still cannot believe that much sound can come from 2.5 watts LOL...amazing.
[11:25:10] <Connor> Man.... I just came home from taking my Wife to the Doctor... We had a bird build a nest in our Car port.. and we watched the babies grow up to be fledglings.. Was watching them from the car when we pulled up. One of them managed to land on the step going into the house.. I told my wife he's in a bad spot I'll need to come out and move him.. opened the door to help her inside.. and the bird hopped into the house.. right as I walked in.. and RIGHT UNDE
[11:25:32] <Connor> I stepped on it.. (I didn't even see it come into the house) Wife saw the whole thing and couldn't tell me in time..
[11:25:33] <zeeshan|2> :D
[11:25:51] <zeeshan|2> =/
[11:25:55] <Connor> Bird squawked and died 30 seconds later.. I didn't even put full weight on it..
[11:26:03] <Connor> This week is fired..
[11:26:16] <mozmck> bummer! I've done in a kitten that way :(
[11:26:24] <zeeshan|2> lose some weight
[11:26:25] <zeeshan|2> both of you
[11:26:52] <Connor> It was JUST learning how to fly... Wife even took a picture of it 30 seconds before the incident..
[11:26:56] <Connor> she's really torn up.
[11:28:57] <Smidge204__> Hundreds of thousands of birds die for all sorts of reasons. I wouldn't feel that bad - not like you ground your heel into it or anything.
[11:29:53] <Connor> Smidge204__: Yea.. but.. the problem is... we watched them grow up.. and WAS just admiring it.. and then POOF.
[11:29:55] <PetefromTn_> https://www.youtube.com/watch?v=MmfbPsPmfp4
[11:30:34] <Smidge204__> True enough, but even if you hadn't accidentally stepped on it it might've died anyway since it was on the ground
[11:30:36] <zeeshan|2> connor similar thing happened to me
[11:30:43] <zeeshan|2> i watched baby rabbits grow up in my backyard
[11:30:52] <zeeshan|2> one day i come back, i find one of them slaughtered
[11:31:01] <zeeshan|2> a hawk/cat/fox
[11:31:06] <zeeshan|2> ate it for dinner
[11:31:54] <ssi> I want a hawkcatfox!
[11:31:57] <ssi> sounds like an amazing pet
[11:32:05] <zeeshan|2> ssi http://i.imgur.com/wvdhjOG.jpg
[11:32:11] <zeeshan|2> 4 min die cutting operation
[11:32:13] * zeeshan|2 loves cnc
[11:32:26] <ssi> excellent
[11:32:26] <Connor> Momma Bird and it's other 2 siblings were out there too..
[11:33:08] <zeeshan|2> connor you're fucked
[11:33:11] <zeeshan|2> theyre gonna attack you
[11:33:36] <mozmck> no, but they won't hop under his feet I bet!
[11:33:53] <Smidge204__> Depends... some species of bird really hold a grudge.
[11:33:57] <jdh> they have already forgotten that little Freddy even existed.
[11:34:04] <zeeshan|2> jdh lol
[11:34:15] <Smidge204__> Crows will hunt you down, man.
[11:34:34] <Smidge204__> Even months later
[11:34:41] <zeeshan|2> years later dude
[11:34:47] <zeeshan|2> did you see that crow research video?
[11:34:55] <Smidge204__> With the toolmaking?
[11:34:56] <zeeshan|2> the people who did experiments on them
[11:35:04] <zeeshan|2> they came back after 5 years
[11:35:09] <zeeshan|2> and the crows still attacked them
[11:35:10] <Smidge204__> Ah yeah
[11:35:17] <jdh> anyone have a specific harbor freight pump suggestion for a water cooled spindle?
[11:35:32] <Smidge204__> That's some grade-A Hitchcock sh*t there.
[11:35:35] <zeeshan|2> lol
[11:36:23] <Smidge204__> jdh: If you know the GPM required it should be pretty straightforward
[11:37:30] <jdh> nothing is taht simple
[11:38:19] <Smidge204__> Of course not...
[11:38:40] <Smidge204__> What about thermal requirements? How much heat does it generate?
[11:38:57] <jdh> no clue, never powered it up.
[11:39:16] <Smidge204__> What size hose connections?
[11:39:34] <jdh> no clue, but I can make anything fit.
[11:39:42] <Loetmichel> jdh: the smalles that can cope with more than 1m height
[11:39:55] <Loetmichel> the gpm is irrelevant
[11:40:03] <Loetmichel> a trickel is enough anyways
[11:40:13] <Loetmichel> the spindle has only 800W full load
[11:40:24] <jdh> mine says 1500w
[11:40:27] <Loetmichel> 90% of the time it will not even heat up without a pump
[11:40:35] <Smidge204__> No idea what size the hole is?
[11:40:40] <Loetmichel> ok, so yours is a bit bigger
[11:40:40] <zeeshan|2> depends on the rpm..
[11:40:42] <jdh> it's the bigger spindle
[11:40:44] <Loetmichel> still no problem
[11:40:48] <jdh> 80mm
[11:41:28] <jdh> was going to make a pre-hurricane run to HF on the way home. I imagine I will be stuck inside for a day.
[11:42:05] <Smidge204__> 1500W is the overall power, so if losses to heat are more than 10% of that you have other problems
[11:42:27] <Smidge204__> 150W is bupkis... so yeah just about anything
[11:43:03] <Loetmichel> mine is a pump meant for an indoor fountain
[11:43:26] <Loetmichel> ... it has issues with bringing up the water to the spindle when it has drwan air in the circuit
[11:43:28] <Smidge204__> I was thinking medium aquarium pump
[11:43:39] <jthornton> is that why it is a little cool today... a hurricane somewhere
[11:43:51] <Loetmichel> ... but when the system is filled it works and pumps more than enough
[11:43:56] <jdh> wouldn't think an aquarium pump could handle the head
[11:44:28] <Smidge204__> Closed loop. As Loetmichel is saying, if you pritnt he discharge tube down to the reservoir it's fine
[11:44:49] <Loetmichel> https://www.youtube.com/watch?v=a9Ov69t0uwo
[11:45:23] <Loetmichel> it doesent get much smaller than tat pump ;-)
[11:45:40] <jdh> heh... I think I have one that looks just like that.
[11:45:53] <Smidge204__> It's sort of like a siphon effect, and the pump just has to make up the relatively small difference
[12:04:48] <IchGuckLive> hi all B)
[12:05:24] <IchGuckLive> reading the logs today real activ channel ;-)
[12:05:41] <IchGuckLive> K6MLE: ?
[12:06:43] <IchGuckLive> CaptHindsight: Radar Tornado warnings hedding your hometown
[12:14:24] <gkamysz> Holy moly! i might need a set of speakers that big.
[12:16:33] <gkamysz> I built a transmission line 10" sub for my truck 15 years ago then it sat in my theather until I stopped using it. i've been thinking about building a TL for a 6" sony component set I have.
[12:22:40] <gkamysz> finally. my box from yesterday is running. i installed libgl1-mesa-swx11
[12:23:12] <gkamysz> for some reason this wiped out linuxcnc so I had to reinstall it
[12:23:47] <gkamysz> it looks like it's alive so I'll connect it to my machine for a test drive
[12:29:46] <gkamysz> Are those chinese spindles up to cutting metal yet?
[12:52:39] <SpeedEvil> gkamysz: Of course. Depends how much yo upay
[13:04:19] <gkamysz> back when I needed one they were junk so I made my own.
[13:05:48] <IchGuckLive> SpeedEvil the 14spindle mashine is quite usefull to copy Replics of Nadonna and church stuff
[13:06:10] <SpeedEvil> It says independant
[13:09:27] <Jymmm> IchGuckLive: Cone bra?
[13:09:58] <IchGuckLive> german like them
[13:10:50] <Jymmm> IchGuckLive: Well, yeah, they're freaky like that... http://assets.nydailynews.com/polopoly_fs/1.95551.1313899425!/img/httpImage/image.jpg_gen/derivatives/gallery_1200/gal-madonna-6-jpg.jpg
[13:10:51] <gkamysz> 14spindle?
[13:13:06] <gkamysz> The mill runs again. I can see that movement is much smoother compared to 2.2.8 that I was running so 3D surfacing might run faster and smoother.
[13:16:19] <CaptHindsight> IchGuckLive: nothing today, hurricane down in the Carolinas
[13:27:26] <CaptHindsight> jdh: http://www.harborfreight.com/264-gph-submersible-fountain-pump-68395.html testing this one, been running for 2 days submerged in coolant
[13:31:57] <Smidge204__> Harbor Freight - the tool department Walmart wishes it had.
[13:33:34] <stt_michael> harbor freight ish good
[13:34:12] <Smidge204__> Depends on what you're getting, and usually a little bit of luck
[13:34:33] <stt_michael> yea
[13:34:39] <CaptHindsight> doesn't Walmart stock Stanley tools at their stores?
[13:34:54] <Smidge204__> I think so
[13:35:32] <CaptHindsight> all the same types of stores in China carry Stanley
[13:37:48] <Smidge204__> Stanley is meh. It's hard to make a genuinely bad wrench, though
[13:38:00] <Smidge204__> For example
[13:38:07] <CaptHindsight> HF uses the Pittsburgh label on many hand tools
[13:38:29] <Smidge204__> Yup
[13:38:30] <CaptHindsight> heh like the 4" long combo set up to 36mm :)
[13:38:31] <Jymmm> Smidge204__: Wanna bet?
[13:38:39] <Smidge204__> Jymmm: Didn't say impossible :p
[13:38:46] <Jymmm> Smidge204__: They don't call them knuckle busters for nothing.
[13:39:24] <CaptHindsight> Chicago Pneumatic is another
[13:40:11] <CaptHindsight> the tools stores there are interesting, usually no brand name on them
[13:41:02] <CaptHindsight> cordless drills are sold by the battery voltage, the price goes up with the voltage
[13:41:27] <Smidge204__> Anything in the 277-480V range? :D
[13:41:31] <CaptHindsight> and you haggle over price
[13:42:01] <Smidge204__> What is there to haggle over?
[13:42:34] <Smidge204__> Are they damaged or visibly defective?
[13:43:18] <Jymmm> Smidge204__: Haggle paying $16 for a $2 drill
[13:43:39] <Smidge204__> Oh... just plain ol' gouging
[13:46:17] <gkamysz> if you are a foreigner the price triples
[13:46:20] <CaptHindsight> http://www.bloomberg.com/image/i3GzFFSgmJeQ.jpg http://www.greatmirror.com/images/medium/012956.jpg
[13:46:33] <CaptHindsight> usually in places like these
[13:53:03] <Smidge204__> Thanks for the reminder just how different cultures can be.
[13:54:01] <IchGuckLive> im off BYE
[13:54:31] <CaptHindsight> I still haven't found a seller of high end tools. The culture there is like HF. You buy cheap and often.
[13:55:51] <CaptHindsight> all those low cost welders for example, they are made to be carried to workplace to workplace on your scooter and work well enough for a few months or year
[13:57:07] <Smidge204__> :/
[13:57:53] <Smidge204__> Do you suppose that's an affordability problem, or a concern over crime/theft of more expensive kit?
[13:58:15] <CaptHindsight> when I show them 50 year old Bridgeports or 20 year old Matsuuras it doesn't compute with them
[13:59:11] <CaptHindsight> you buy a welder, chop saw, drill etc for a year or two then buy the next gen
[13:59:45] <Smidge204__> Sounds much more expensive than just buying something that'll last, assuming you can get it
[13:59:54] <CaptHindsight> they would rather spend $200 every year for 5-10 years vs $1000-2000 every 5-10 years
[14:00:15] <Smidge204__> :/
[14:00:27] <Smidge204__> That's a depressingly common attitude
[14:00:48] <gkamysz> just needs to be good enough to work for a while
[14:01:36] <Smidge204__> Maybe for something you'll only need to use rarely.
[14:01:42] <mozmck> $200 every year for 5-10 years is the same money as $1000-$2000 every 5-10 years
[14:02:00] <Smidge204__> If and only if the purchasing power of that money doesn't change
[14:02:23] <mozmck> If that's accurate then it actually makes sense - kind of like paying on time except you own the thing.
[14:02:23] <CaptHindsight> mozmck: yes, they don't think long term
[14:02:27] <Smidge204__> something something opportunity costs
[14:02:55] <gkamysz> back in 2003 on the main highway to beijing airport workers had carts and shovels working on the curbs. not a single powered machine in sight.
[14:02:57] <Smidge204__> Also, if a higher quality tool increases your productivity, that is also something to consider
[14:03:07] <mozmck> CaptHindsight: but if the price is the same, why spend more?
[14:03:08] <gkamysz> Bamboo scaffolding on highrises was something too
[14:03:35] <CaptHindsight> gkamysz: there is still a lot of that
[14:03:44] <gkamysz> of course manpower is cheap
[14:03:51] <CaptHindsight> but factories are all automated and high tech
[14:05:05] <gkamysz> because they still have to be cheaper than vietman or india whatever the next place will be
[14:05:23] <Smidge204__> Race to the bottom!
[14:05:37] <Smidge204__> It'll be the end of us all :/
[14:05:52] <CaptHindsight> China has poured more concrete in the past 5 years than the US in the past 100
[14:06:02] <gkamysz> but it will fall apart in 10
[14:06:14] <Smidge204__> Mostly for no reason, if my understanding is correct
[14:06:27] <gkamysz> buildings i saw that were just 5-10 years old were crumbling
[14:06:38] <Smidge204__> And mostly empty
[14:06:48] <CaptHindsight> but that 10 years off :)
[14:07:22] <gkamysz> people betting on the future? that didn't come
[14:07:31] <CaptHindsight> http://www.wired.com/2014/06/how-much-cement-has-china-used/
[14:08:28] <CaptHindsight> now they are moving people from the countryside into the empty new cities
[14:09:05] <gkamysz> wow it will still be interesting how it works out
[14:09:36] <Smidge204__> [pictures of fallen over building here]
[14:13:51] <CaptHindsight> at least their falling buildings don't defy physics

[14:17:07] <Smidge204__> Was thinking of that one specifically
[14:23:04] <Loetmichel> hmmm
[14:23:44] <CaptHindsight> part of that corner cutting
[14:24:39] <Loetmichel> as i have ordered my fith of these: http://www.ebay.de/itm/181453363761 do the channel think its possible to make a copy of that casing out of Stainless steel on a 3 axis cnc mill and a lathe? and how to put a hardened glass in it instead of the plastic?
[14:24:52] <Loetmichel> worth giving it a try or hopeless?
[14:25:25] <Loetmichel> (the other four lost their chrome platin in less than half a year)
[14:25:28] <Loetmichel> plating
[14:28:30] <CaptHindsight> http://www.chinadaily.com.cn/china/2009-07/03/content_8376126.htm
[14:31:54] <SpeedEvil> Why not sapphire?
[14:33:13] <jdh> CaptHindSight: I was looking at the smallest version of that. 92gpm or so
[14:33:22] <SpeedEvil> http://deloachwatchservice.com/repair/sapphire.htm
[14:34:05] <Loetmichel> SpeedEvil: look at the ebay link: not round
[14:34:16] <SpeedEvil> Well, duh
[14:34:19] <SpeedEvil> you'd need to cut it
[14:34:20] <Loetmichel> ... and polycarbonate ;-)
[14:34:56] <SpeedEvil> I wasn't suggesting that particular service - just that they;'re available
[14:35:02] <Loetmichel> how to cut saphire glass? diamont grinding pin and loads of water?
[14:35:09] <SpeedEvil> Diamond disk works
[14:35:22] <Loetmichel> nice
[14:36:34] <Loetmichel> o would have thought saphire is so close to brinell10 that diamond won't cut it without using up a large amount of discs
[14:36:56] <SpeedEvil> the disk is quite thin
[14:36:58] <SpeedEvil> which helps
[14:37:04] <Loetmichel> still no idea if its possible to do that casing in stainless on a small 3 axis CNC mill
[14:39:13] <Loetmichel> and yes, i know that this will be a tedious task
[14:39:21] <Loetmichel> and "not worth the money"
[14:39:44] <SpeedEvil> Meh
[14:39:45] <Loetmichel> ... i am just fed up with bying a new watch every few months
[14:39:48] <CaptHindsight> jdh: I looked at them all and read the reviews, they are all over rated
[14:40:05] <Loetmichel> and they tend to get more and more expenive over the years.
[14:40:20] <Loetmichel> the first one i bight in the late 80ties was 20 DM ;-)
[14:40:20] <CaptHindsight> jdh: so I got the largest one of the cheapies
[14:40:43] <CaptHindsight> looks like a job for lost wax casting
[14:40:55] <SpeedEvil> http://www.bgsusa.com/ - heh
[14:40:59] <SpeedEvil> Straight out of 1985
[14:41:07] <SpeedEvil> 1975 actually
[14:41:20] <SpeedEvil> It looks like a dead-on copy of the paper catalogs I found in the attic of tooling
[14:41:35] <gkamysz> http://youtu.be/z-PlLHDgamE
[14:41:43] <SpeedEvil> CaptHindsight: Lost plastic
[14:42:14] <SpeedEvil> It's a bit annoying that stainless has such a ridiculous melting point
[14:42:20] <CaptHindsight> SLA the sacrificial mold
[14:43:36] * SpeedEvil wonders about aluminium bronze
[14:44:19] <SpeedEvil> Loetmichel: however
[14:44:27] <SpeedEvil> Loetmichel: Working solely from memory, and without a net.
[14:44:54] <SpeedEvil> Loetmichel: The watch element in that is basically cylindrical, and will fit just fine in a cylindrical recess
[14:45:20] <SpeedEvil> with a couple of appropriate holes and springs for buttons - you can probably reuse the old ones
[14:45:47] <Loetmichel> it is
[14:45:51] <Loetmichel> more or less
[14:46:02] <Loetmichel> and i think i can
[14:46:07] <SpeedEvil> So, you don't really need to copy it accurately.
[14:46:14] <SpeedEvil> Which makes it enormously easier
[14:46:20] <Loetmichel> if i get hem otu of the resin casing without damage
[14:46:29] <SpeedEvil> They're not fixed in
[14:46:37] <SpeedEvil> they come out easily once you take the back off.
[14:46:38] <Loetmichel> SpeedEvil: i just want to ;)
[14:46:47] <Loetmichel> and no, they dont
[14:46:53] <SpeedEvil> yes - I was meaning you won't get damage unless you go at it with a hammer
[14:46:57] <Loetmichel> these case is waterproof
[14:47:00] <SpeedEvil> (don't do that)
[14:47:05] <Loetmichel> there are sealings inside the buttons
[14:47:18] <SpeedEvil> indeed. Which is why I said reuse, as making might be annoying
[14:47:23] <Loetmichel> and VERY litte teethed rings on the inside
[14:48:06] <SpeedEvil> Casting it out of silver, after making a mould using the CNC might be interesting too
[14:48:39] <Loetmichel> silver with a stainless arm band... seems like a break in style to me ;.)
[14:48:52] <SpeedEvil> Well - I diddn't say stainless band :)
[14:48:56] <SpeedEvil> That's the next project
[14:49:14] <Loetmichel> i want it to look exaclty like it does now
[14:49:22] <SpeedEvil> ah
[14:49:23] <Loetmichel> ... just in unbreakable ;-)
[14:50:18] <Loetmichel> i.e Stainless intead of chromed resin and Saphire or gorilla instead of polycarbonate
[14:50:48] <SpeedEvil> Well, polycarbonate may actually be unbreakable :)
[14:51:09] <Loetmichel> i am just sick of buying tham new every half a year because of lost chrome and scratches in the glass
[14:51:12] <Loetmichel> "glass"
[14:51:18] <SpeedEvil> http://www.aliexpress.com/item/Optical-Sapphire-Window/582289991.html
[14:51:33] <SpeedEvil> Is an indication of the sort of price - it's not bad at all
[14:51:43] <SpeedEvil> And I don't think that'll quite work
[14:51:54] <Loetmichel> too thick ;-)
[14:52:12] * SpeedEvil passes Loetmichel a 5000 grit diamond hone.
[14:52:35] <Loetmichel> why did i anticipate that?
[14:52:38] <Loetmichel> :-)
[14:53:54] <SpeedEvil> From memory, there are no real complex shapes on it, and with a couple of different fixtures, you should be able to do it just fine
[14:54:05] <SpeedEvil> The strap attachment may be annoying
[14:56:18] <Loetmichel> hmmm
[14:56:21] <CaptHindsight> can't you just write an app for your smartphone that looks like that watch? :)
[14:56:29] <Loetmichel> i should buy some stainless then...
[14:56:46] <SpeedEvil> Try it out in Al
[14:56:49] <Loetmichel> CaptHindsight: thats the only watch i can toerat at my arm
[14:57:00] <Loetmichel> i dont like analogs
[14:57:03] <CaptHindsight> yeah, you get used to certain things
[14:57:08] <CaptHindsight> i understand
[14:57:11] <Loetmichel> and cant tolerate plastic or leather straps
[14:57:41] <CaptHindsight> I used to break any watch I'd wear in a few weeks
[14:57:47] <SpeedEvil> https://play.google.com/store/devices/details/LG_G_Watch_White_Gold?id=lg_g_watch_white
[14:57:57] <Loetmichel> i have fires one of these across the workshop...
[14:58:03] <SpeedEvil> I mean - I might consider that, if it was a fifth of the price, and actually robust
[14:58:10] <Loetmichel> hail to the spring ons in the strap
[14:58:31] <SpeedEvil> And had wifi as well as bluetooth
[14:58:36] <Loetmichel> (got caugtht in the bench drills collet)
[14:59:41] <Loetmichel> like i said: no plstic or leather straps: the skin on my arm starts to decay under them
[14:59:57] <Loetmichel> stainless straps it is!
[15:00:08] <CaptHindsight> i once reached into the space between the alternator and the engine block while my watched touched the terminal, it melted while on my wrist
[15:00:18] <CaptHindsight> watched/watch
[15:00:19] <Loetmichel> ouch
[15:00:38] <Loetmichel> s/ons/pins
[15:01:21] <Loetmichel> after that "fire away" incident i wore a blue and black "wrist strap" instead of the steel one for a week ;-)
[15:02:03] <Loetmichel> luckily the pins in the straps gave way before my arm did ;-)
[15:08:33] <Jymmm> That's exactly why I NEVER wear jewlery, especially when reaching into a 10KV cavity
[15:09:26] <CaptHindsight> I've had 20KV arcs through my arms when working on old CRT monitors, burns on both sides
[15:09:38] <Jymmm> and when I do, my hand is upside down so that the shock doesn't force my hand closed or my arm towards the source.
[15:09:53] <CaptHindsight> no jewelry necessary
[15:10:11] <Jymmm> CaptHindsight: CRt's are one of the cavities I speak of
[15:10:19] <Jymmm> that flyback can be a bitch!
[15:10:53] <SpeedEvil> Jymmm: he got banned on ##electronics.
[15:10:56] <Jymmm> RF PA's are another
[15:11:08] <Jymmm> SpeedEvil: flyback transformer.
[15:11:12] <SpeedEvil> I know
[15:11:15] <SpeedEvil> :)
[15:11:19] <CaptHindsight> everyone knows flyback
[15:11:57] <Jymmm> Finally got my fixture done, just said screw it
[15:12:09] <Loetmichel> CaptHindsight: normal
[15:12:23] <Loetmichel> did that on purpose in my TV repair days
[15:12:48] <Loetmichel> to repell the nosy customers when i repaired a live TVset
[15:13:29] <Loetmichel> just touch the HV cable whre it touchse the Transformer. usually the isolation is not in best shape so you can draw up to 30cm arc there
[15:13:41] <Loetmichel> *brrrzzzzzzzT*
[15:13:57] <Loetmichel> ... aaaand the nosy customer instantly is in the next room ;-)
[15:14:01] <Jymmm> Discharginging the flyback is usually enough of a POP
[15:14:05] <SpeedEvil> If you're confused about the mentions of flybacks, ask your father. :)
[15:14:15] <SpeedEvil> There is now only one vacuum tube in most homes.
[15:14:26] <Jymmm> ?
[15:14:33] <Loetmichel> SpeedEvil: where?
[15:14:41] <Jymmm> the vacum itself?
[15:14:45] <SpeedEvil> Microwave. And solid state microwaves are possible.
[15:14:46] <CaptHindsight> the space between their ears?
[15:14:48] <Loetmichel> (besides the few that have a plasma tv)
[15:14:48] <Jymmm> vacuum cleaner
[15:15:10] <Loetmichel> MW with vaccum tubes?
[15:15:12] <SpeedEvil> yes.
[15:15:23] <Loetmichel> the resonator is evacuated... but a vacuum tube?
[15:15:25] <SpeedEvil> Every single one.
[15:15:26] <Loetmichel> i doubt it
[15:15:30] <Jymmm> There are no vacuum tubes in a MW
[15:15:36] <SpeedEvil> It's a special purpose vacuum tube.
[15:15:40] <Jymmm> Nope
[15:15:48] <Loetmichel> no heating filament
[15:15:49] <Jymmm> I take em apart for the xfmr's =)
[15:15:52] <SpeedEvil> It has a heater.
[15:15:52] <Loetmichel> -> no vacuum tube
[15:16:08] <Loetmichel> it has?
[15:16:11] <Jymmm> magnatron yes, but no vacuum tube
[15:16:20] <CaptHindsight> http://en.wikipedia.org/wiki/Cavity_magnetron
[15:16:28] <Loetmichel> i know only magnetrons without heater
[15:16:38] <SpeedEvil> All microwave oven magnetrons have heaters
[15:16:44] <Jymmm> oh, and giant donut magnets
[15:17:02] <Jymmm> ceramic sadly
[15:17:22] <Jymmm> so-so in strength
[15:17:32] <SpeedEvil> http://www.repairfaq.org/sam/micfaq.htm#micmagconm
[15:18:11] <Loetmichel> strange. never noticed the heater
[15:18:21] <Loetmichel> and i dismantled quite a few MW
[15:18:41] <SpeedEvil> There are two visible connections to the tube.
[15:18:48] <SpeedEvil> But one is ground to the body
[15:18:51] <SpeedEvil> It's a triode
[15:19:06] <SpeedEvil> Well - three terminal device
[15:20:14] <Jymmm> SpeedEvil: That may have been at one time, but today, there was no vacuum anything. Things change *shrug*
[15:20:40] <Swapper_> Is it possible to get linuxcnc to read status from the comport via ascii commands and get them to display onscreen ?
[15:20:59] <Swapper_> onyone done somthing like that ?
[15:21:03] <SpeedEvil> There are today as far as I'm aware no commercial solid state microwave ovens. They can be made, but the semiconductors cost about $1K
[15:21:41] <Jymmm> SpeedEvil: Realize microwaves used to spark with metal, not as much these days.
[15:21:54] <SpeedEvil> That's got nothing to do with the magnetron
[15:22:12] <Jymmm> SpeedEvil: No, but it does in the way they are designed these days
[15:22:14] <SpeedEvil> Well - it's subtleties of design of teh feedline.
[15:23:06] <SpeedEvil> Sure - but in every microwave oven is a magnetron with a heater and vacuum inside.
[15:23:22] <Loetmichel> still no vave
[15:23:25] <Loetmichel> +l
[15:23:29] <Jymmm> show me the vacuum photos and I'll believe you
[15:23:36] <SpeedEvil> I never said valve.
[15:24:15] <Jymmm> neither did I , but if there is a vacuum, there needs to be a seal too.
[15:24:21] <Loetmichel> vacuum tube
[15:24:50] <Jymmm> still needs a seal of some sort and all I have ever seen is RF gasketing
[15:25:28] <Jymmm> SpeedEvil: I'm just saing that I haven't seen it, not that it doesn't exist.
[15:25:33] <Jymmm> saying*
[15:25:37] <SpeedEvil> Please find one source - any source that says there exist non vacuum magnetrons.
[15:26:13] <Loetmichel> i am not that good in magentron physics
[15:26:17] <Loetmichel> but can there be?
[15:26:19] <Jymmm> Just take one apart, show me the gasket/seal that would hold a vacuum?
[15:27:21] <Jymmm> http://blockyourid.com/~gbpprorg/mil/emp1/emp-14.jpg
[15:27:27] <SpeedEvil> https://www.youtube.com/watch?v=j3k6L8bLUqI
[15:27:37] <SpeedEvil> @7:23
[15:27:41] <Jymmm> http://www.blinkenbyte.org/magnetron/magnetron08.jpg
[15:28:15] <SpeedEvil> It's all welded
[15:28:23] <SpeedEvil> the feedthrough is a the pink bit
[15:29:11] <SpeedEvil> Typically berillium oxide - this is sealed with a gas-tight seal to the stainless
[15:29:24] <Connor> WTF is that Jymmm ? (04:09:10 PM) Jymmm: http://blockyourid.com/~gbpprorg/mil/emp1/emp-14.jpg
[15:29:38] <SpeedEvil> It's a cutthrough of a magnetron
[15:29:55] <SpeedEvil> https://en.wikipedia.org/wiki/Cavity_magnetron
[15:30:04] <SpeedEvil> The cavity magnetron is a high-powered vacuum tube that generates microwaves using the interaction of a stream of electrons with a magnetic field
[15:30:05] <SpeedEvil> ...
[15:30:12] <Jymmm> Connor: http://blockyourid.com/~gbpprorg/mil/emp1/
[15:30:59] <Jymmm> Connor: Heh, an EMP bomb from the looks of that page
[15:31:18] <Jymmm> basically a sparc gap transmitter I suppose
[15:31:22] <Connor> 2.45 GHZ EMP
[15:31:37] <Connor> Probably would fry all WiFi in it's path.
[15:31:51] <Jymmm> Connor: I bet more broadband than that
[15:32:41] <Jymmm> That would be fun to play with though.
[15:33:09] <Jymmm> GET OFF THE DAMN PHONE AND DRIVE!!!
[15:39:41] <Loetmichel> Jymmm: *tuuuiiiiiiiiii* *BOMPF*
[15:40:02] <Loetmichel> and all cars in 1 mile diameter instantly shut off
[15:40:10] <Loetmichel> ... forever ;-)
[15:40:27] <Jymmm> Loetmichel: No, that's only at HF
[15:40:40] <Jymmm> 100W HF
[15:42:15] <Loetmichel> ah, i see now
[15:42:31] <Loetmichel> only a powerful magentron and a dish
[15:43:40] <Loetmichel> i thought more in the way of "putting insane abounts of cuirrent thru a copper coil and then implode it with fast explsives to a singular point"
[15:44:30] <Loetmichel> ... which will make quite an impressive "real" EMP
[15:45:43] <Loetmichel> without the destruction of a fission bomb
[15:56:33] <gkamysz> I want to try melting metal for casting in the microwave
[15:57:05] <CaptHindsight> sounds like a death ray
[16:00:14] <kengu> interesting idea
[16:00:16] <gkamysz> http://www.alloyavenue.com/vb/showthread.php?4044-Microwave-casting-is-a-reality!
[16:03:53] <gkamysz> I read about it a couple years ago. irc, one method just heats the metal, while another uses a crucible which absorbs microwaves
[16:12:14] <Deejay> gn8
[16:21:39] <SpeedEvil> I replaced the waveguide cover in my microwave with glass.
[16:21:57] <SpeedEvil> After one cooking cycle, I had a shattered bit of glass and blobs
[16:22:16] <SpeedEvil> reassembly revealed it had neatly melted a hole, then shattered on cooling
[16:29:29] <gkamysz> the glass table is suppsedly there to absorb the engergy if you were to run it empty. there are some youtubes about melting glass in the microwave
[16:31:34] <gkamysz> my upgrade from 2.2.8 to the latest version was less traumatic than expected. i should have done it a while ago. it runs and even the linuxcnc post for hsmexpress works.
[16:33:57] <gkamysz> now, i really have to finish my lathe retrofit. i didn't know until i installed it that hsmexpress has lathe
[16:39:32] <PCW> I know someone that worked at a place where they made giant magnetrons and amplitrons for debugging buildings and other such uses
[17:04:23] <Jymmm> PCW: animal or mechanical bugs?
[17:04:39] <PCW> electronic
[17:05:03] <Jymmm> ah
[17:05:55] <PCW> These were big enough tubes that they had ionization pumps to keep the vaccum
[17:07:16] <Jymmm> PCW: I don't know what that means, but ok =)
[17:08:10] <Jymmm> Just curious... would "FUCK CANCER" be considered politically correct?
[18:53:02] <cncformywife> hi
[18:53:47] <cncformywife> someone can help me with some stuff?
[18:56:37] <mozmck> making a cnc for you wife?
[18:59:04] <cncformywife> yes
[18:59:41] <mozmck> ask and someone can probably help.
[19:00:33] <cncformywife> she is want the ability to make engraving in light metal like
[19:00:38] <cncformywife> mozmck: ^
[19:00:52] <mozmck> ok
[19:03:14] <cncformywife> how i calculate the force of the milling process?
[19:03:41] <cncformywife> mozmck: ^
[19:03:57] <mozmck> hmm, I don't know on that, but it will not be much for light engravings
[19:04:23] <mozmck> are you trying to figure out how strong a machine you need?
[19:04:41] <mozmck> how sturdy that is?
[19:05:56] <cncformywife> yes, how ridged i need to build it.
[19:08:29] <cncformywife> mozmck: it have to be very precise, she want it for jewelry making.
[19:10:13] <mozmck> I don't know the answer for you. You might start out looking at machines designed to do what you want, and that may give you some ideas.
[19:11:57] <mozmck> http://www.visionengravers.com/products/
[19:12:26] <mozmck> http://www.gravograph.us/engraving-machines/Overview.php
[19:15:08] <cncformywife> this are very expensive machines and not precise for jewelry.
[19:16:00] <cncformywife> i want to know how lo calculate it.
[19:16:13] <cncformywife> i see this diagram https://www.google.co.il/search?q=milling+force&espv=2&source=lnms&tbm=isch&sa=X&ei=l-y1U4m3A8XbPIGwgLgJ&ved=0CAYQ_AUoAQ&biw=1024&bih=485&dpr=1.25#facrc=_&imgdii=_&imgrc=VBgxKXYpemNoeM%253A%3B6o5FXiLB2aZVtM%3Bhttp%253A%252F%252Fmanufacturingscience.asmedigitalcollection.asme.org%252Fdata%252FJournals%252FJMSEFK%252F926545%252Fmanu_134_6_061006_f003.png%3Bhttp%253A%252F%252Fmanufacturingscience.asmedigitalcoll
[19:19:07] <CaptHindsight> cncformywife: what will you do with the results of computing the range of cutting forces?
[19:21:57] <CaptHindsight> cncformywife: have you looked at small mills that can easily handle engraving?
[19:23:51] <cncformywife> if i will know how much force i need to "push" the cutting bit in to the material, i will know how ridgid to make the machine
[19:24:32] <cncformywife> yes, i look, in the internet and i go to several places,
[19:26:12] <cncformywife> CaptHindsight: simple and small are not precise, small and precise are extremely expensive.
[19:26:38] <cncformywife> CaptHindsight: you can help me?
[19:27:29] <CaptHindsight> http://www.kennametal.com/en/resources/calculators/end-milling-calculators/force-torque-and-power.html here's a calc for end milling, this will be more than what you'll see, but it's a good overestimate
[19:27:32] <CaptHindsight> bbl
[19:29:00] <cncformywife> bbl?
[19:30:03] <cncformywife> i need the "End Mill Nomenclature" ?
[19:30:20] <cncformywife> or the "Machining Conditions"
[19:30:23] <cncformywife> CaptHindsight: ?
[19:34:12] <cncformywife> what is "Effective cutting diameter"
[19:34:28] <cncformywife> the diameter of the cutting bit?
[19:34:35] <cncformywife> help!!
[19:34:50] <jfigie> yes it is diameter of cutter
[19:35:30] <jfigie> used to calculate cutter speed
[19:36:00] <cncformywife> 3/32" inch
[19:36:47] <jfigie> http://en.wikipedia.org/wiki/Speeds_and_feeds
[19:37:26] <cncformywife> jfigie: i need to find the side force that i need to "push" the bit.
[19:38:08] <jfigie> ok I don't know how to calculate that.
[19:38:20] <jfigie> not too much for a 3/32 cutter
[19:38:27] <jfigie> force that is
[19:38:42] <jfigie> of course it depends on the material and the cutting speed
[19:39:25] <cncformywife> but i need it very very accurate in titanium
[19:39:44] <jfigie> and depth of cut
[19:40:04] <jfigie> and number of cutting teeth
[19:40:20] <zeeshan|2> theres 5 major parameters. depth of cut, feed rate, cutting speed, tool material, work piece material
[19:40:32] <zeeshan|2> but if you're trying to design only
[19:40:40] <zeeshan|2> you'll take worse case scenario for all of them
[19:40:53] <cncformywife> the depth is small 1 mm~
[19:40:54] <zeeshan|2> which is something you need to decide on :p
[19:41:12] <zeeshan|2> are you sure titanium is the only material you'l be cutting?
[19:41:57] <cncformywife> gold, silver, brass, hard wood.
[19:42:06] <zeeshan|2> okay those arent really hard materials
[19:42:08] <mozmck> The smallest little engraving machine around would probably work. I think you need to worry more about spindle vibrations than side forces.
[19:42:14] <zeeshan|2> so i guess, titanium would be your worst case material
[19:42:30] <zeeshan|2> that gives you the variable 'surface feet per minute'
[19:42:33] <zeeshan|2> 50
[19:42:39] <zeeshan|2> er..
[19:42:42] <cncformywife> mozmck: NO! thay not accurate!!
[19:42:44] <zeeshan|2> actually i'd design for 200sfm.
[19:43:05] <cncformywife> you have a-lot of backlash
[19:43:11] <mozmck> you build it more accurate then.
[19:44:07] <cncformywife> the accurate machines start at 20K$
[19:44:11] <mozmck> use fine pitch, high quality ball screws, good quality linear ways and bearings etc.
[19:44:28] <zeeshan|2> you can have accurate lead screws
[19:44:40] <zeeshan|2> but tool deflection/machine deflection would suck
[19:44:40] <zeeshan|2> :p
[19:45:04] <jfigie> hmm it think you want your machine to be able to provide way more force than the minimum otherwise you will probalby have a hard time controlling the position and velocity
[19:45:31] <cncformywife> but what size of linear rails? and screw?
[19:45:50] <zeeshan|2> cncformywife: it's not as simple as what size rails
[19:46:04] <zeeshan|2> you need to determine the worst case cutting force for your application
[19:46:19] <zeeshan|2> once you do that, you need to determine the type of geometric rail configuration you want
[19:46:25] <zeeshan|2> ie simple supported beams (typically)
[19:46:33] <zeeshan|2> from there you can use deflection of beams formulas
[19:46:40] <zeeshan|2> to determine the bead size / cross section
[19:46:42] <zeeshan|2> *beam
[19:47:12] <cncformywife> titanium it the worst case.
[19:47:39] <cncformywife> now i design it in solidworks.
[19:48:01] <zeeshan|2> okay if youre gonna use fea
[19:48:06] <zeeshan|2> then you just need your cutting forces
[19:48:10] <jfigie> I think one way would be to have someone cut some titanium under your conditions and measure the motor current
[19:48:11] <zeeshan|2> and the 'worst case position'
[19:48:33] <jfigie> then use the Kt of the motor to determine the torque applied
[19:48:52] <zeeshan|2> jfigie: that's exactly how they come up with material removal rates
[19:49:13] <zeeshan|2> it's more accurate just to have a load cell on the motor body
[19:49:22] <jfigie> sure
[19:49:23] <zeeshan|2> to determine the force, and you know the torque arm
[19:49:39] <cncformywife> jfigie: you run... slow... slow...
[19:49:57] <jfigie> load cell a bit harder for a hobbyist
[19:50:20] <zeeshan|2> if a load cell is hard
[19:50:31] <zeeshan|2> then you can make bracket
[19:50:36] <zeeshan|2> and put it on a digital bahtroom scale
[19:50:37] <zeeshan|2> :)
[19:51:38] <jfigie> sure but modifying a machine that already works with scale of load cell is a bit of work that is my point
[19:51:55] <jfigie> much easier to measure current
[19:52:03] <cncformywife> but how i can calculate the optimal force.
[19:52:13] <cncformywife> i can say 30 kg..
[19:53:23] <zeeshan|2> cncformywife: someone already gave you the link
[19:53:26] <zeeshan|2> http://www.kennametal.com/en/resources/calculators/end-milling-calculators/force-torque-and-power.html
[19:53:31] <zeeshan|2> what size tool are you using?
[19:53:31] <cncformywife> yes it is make it.. but maybe 10 kg of force is enough?
[19:53:41] <cncformywife> 3/32"
[19:54:01] <zeeshan|2> how many flutes
[19:54:21] <cncformywife> 2-4
[19:55:33] <cncformywife> i dont know which is the worse case
[19:56:23] <cncformywife> what is the "Vc Cutting speed:"
[19:56:46] <cncformywife> i will say "the fastest..."
[19:57:18] <zeeshan|2> 200 sfm
[19:57:21] <zeeshan|2> put that
[19:57:24] <zeeshan|2> if using carbide
[19:57:25] <zeeshan|2> tool
[19:57:39] <cncformywife> ap Axial Depth of cut:?
[19:57:43] <zeeshan|2> brinell hardness for titanium is 334
[19:58:17] <jfigie> use 3/32 for axial depth
[19:58:19] <cncformywife> 40 HRC ~
[19:58:23] <zeeshan|2> look at the image on the top right
[19:58:27] <zeeshan|2> 0.039 for ap
[19:58:35] <zeeshan|2> and 0.0039 for ae
[19:58:38] <zeeshan|2> er 0.039..
[19:58:42] <cncformywife> 0.09375?
[19:58:46] <cncformywife> ok
[19:58:56] <zeeshan|2> well you said you wanted to machine 1mm deep
[19:58:59] <zeeshan|2> thats 0.039"
[19:59:12] <jfigie> oh sorry 3/32 for radial width
[19:59:38] <zeeshan|2> im getting 20 lb
[19:59:42] <zeeshan|2> of force..
[19:59:46] <zeeshan|2> so i'd design for 3x that :P
[20:00:00] <cncformywife> Required feed per tooth?
[20:00:06] <zeeshan|2> 0.003
[20:00:24] <zeeshan|2> for titanium you should be between 0.003 to 0.010 with carbide
[20:00:35] <cncformywife> what is ? Cm Machinability factor
[20:00:52] <zeeshan|2> just put 1 for that
[20:00:57] <zeeshan|2> same with tool wear factor
[20:01:00] <zeeshan|2> and machine efficiency factor
[20:01:15] <cncformywife> 1.0 1.20 1.4??
[20:01:29] <zeeshan|2> C_m, C_w, E should all be 1.
[20:01:35] <zeeshan|2> don't let them effect the end result
[20:01:50] <cncformywife> 1 is the worse?
[20:02:05] <zeeshan|2> 1 is unity, so shouldnt effect the final answer
[20:03:07] <zeeshan|2> you can set E to .9
[20:03:08] <zeeshan|2> if you want
[20:03:51] <cncformywife> Pm at the motor:12hp ????
[20:03:56] <cncformywife> what??
[20:04:16] <cncformywife> 8.94839846 kilowatts
[20:04:49] <cncformywife> not make sense
[20:04:55] <zeeshan|2> put .9 for E
[20:05:00] <zeeshan|2> it'll fix it
[20:05:37] <cncformywife> Pm at the motor:0.13hp
[20:06:15] <zeeshan|2> sounds about right :p
[20:06:46] <cncformywife> 100W
[20:06:54] <cncformywife> yas!
[20:07:16] <cncformywife> Ft Tangential cutting force:20.04lb
[20:07:36] <cncformywife> this is the "side" force?
[20:07:49] <cncformywife> zeeshan|2: ?
[20:27:05] <cncformywife> zeeshan|2: something really really weird - i change the "d1 Effective cutting diameter:" from 0.09 to 1
[20:27:20] <cncformywife> and i get less force!!
[20:27:26] <cncformywife> how??
[20:27:41] <jdh> you got a cnc for your wife?
[20:29:19] <Jymmm> jdh: Sure, just like you did =)
[20:29:46] <jdh> might be a nice trade. Guess it depends on the CNC
[20:30:31] <cncformywife> yes
[20:30:59] <jdh> are you happy with it? do you miss her?
[20:31:59] <ssi> sounds like a good deal
[20:32:30] <jfigie> I would get a cnc for my wife and one for me too. Then I would have 3 machines
[20:32:35] <jfigie> 2 machines
[20:32:39] <cncformywife> she want and i'm make it.
[20:34:22] <cncformywife> back to the calculation..
[20:36:02] <cncformywife> how come that i need less force with bigger cutting bit?
[20:36:51] <jfigie> yes that is interesting but the feed rate and spindle speeds are much lower
[20:38:22] <cncformywife> so it is make sense? or something wrong with this calc..
[20:40:16] <jfigie> metal removal rate is now much lower. But often with a larger dia tool you can increase the tooth load you kept it a .003
[20:42:32] <cncformywife> tool load?
[20:42:53] <cncformywife> Reduced feed per tooth:0.003in. (chip load at the cut)?
[20:43:03] <jfigie> tooth load = feed per tooth
[20:44:18] <jfigie> you could probably increase from .003 to .01 or more
[20:44:23] <cncformywife> but is you say 0.003 to 0.010 for titanium
[20:44:57] <cncformywife> i change it to 0.03
[20:45:24] <jfigie> I am just a hobby machinist so I don't really know how much you can go
[20:46:07] <cncformywife> but now in 1" i get Ft Tangential cutting force:43.778lb
[20:46:38] <cncformywife> and in 0.09" i get Ft Tangential cutting force:218.89lb
[20:46:59] <cncformywife> 10 times more!!
[20:47:04] <cncformywife> how???
[20:47:35] <jfigie> you cant cut .09 per tooth. I think I can safely say that
[20:50:17] <McUles> Hi, hope you can help me. Im looking for a cam software which is running with OS X 10.10. Tried pycam, but is not compiling right in Yosemite :(
[20:51:54] <XXCoder> happy pre-july 4th
[20:52:55] <jdh> I'm hoping this storm is gone by the 4th
[20:53:15] <McUles> anyone has an idea?
[20:53:41] <XXCoder> I do. wood glue printer
[20:53:47] <XXCoder> make wood objects
[20:54:07] <jdh> spider printer - print silk objects.
[20:54:43] <McUles> i need one for a milling machine
[20:55:07] <jdh> McUles: no clue on anything that runs natively in osx. Not cheap anyway
[20:55:17] <Jymmm> jdh: and hope your inkjets never escape!
[20:55:28] <XXCoder> lol
[20:55:34] <jdh> yeah, that woudl be creepy
[20:56:41] <jdh> McUles: meshcam perhaps?
[20:56:51] <Jymmm> Eh, had a nest hatch, around 100 or so I'd guess. they stick close to the nest at first. Bleach wiped em all out.
[20:57:13] <XXCoder> heh had fun with wd40 once
[20:57:14] <jdh> murderer
[20:57:29] <XXCoder> found a pretty big spider nest with lots tiny spiders near it
[20:57:31] <cncformywife> hehe. biosteel!
[20:57:41] <Jymmm> jdh: Come into my home uninvited... damn right
[20:57:41] <XXCoder> I sprayed wd40 all over, they slipped out lol
[20:57:56] <McUles> meshcam looks like a windows Software
[20:58:03] <Jymmm> jdh: 2, 4, 6, or 8 legged
[20:58:07] <XXCoder> funny to see them panic and keep trying to grasp and stay on web
[20:58:13] <cncformywife> http://www.amsilk.com/en/products/biosteel-spidersilk-fibers.html
[20:59:08] <cncformywife> jdh: ^
[21:00:56] <XXCoder> nice
[21:16:02] <cncformywife> high rpm is better?
[21:16:48] <cncformywife> if instead of 18-30K RPM i will go with 150K RPM
[21:18:17] <cncformywife> i will need less rigidity?
[21:36:02] <cncformywife> http://www.ebay.com/itm/Dental-Slow-Low-Speed-Handpiece-Contra-Angle-Air-Motor-Complete-kit-CX235F-M4-/181384450570?pt=LH_DefaultDomain_0&hash=item2a3b5b120a
[21:41:38] <somenewguy> mcules heekscnc?
[21:41:46] <somenewguy> oooh missed him by that much
[21:42:57] <cncformywife> somenewguy: hi
[21:44:34] <somenewguy> howdey
[21:44:37] <somenewguy> howdy?
[21:44:43] <somenewguy> that looks better^
[21:47:01] <cncformywife> somenewguy: you know about cnc machine
[21:47:07] <cncformywife> ?
[21:52:17] <gkamysz> wow 150krpm
[21:53:29] <cncformywife> gkamysz: 150K is slow.. you can find 300K RPM also..
[21:54:02] <cncformywife> dremel is max 30K..
[21:54:04] <gkamysz> sure but what are you doing with it
[21:54:54] <cncformywife> i want to build cnc machine for my wife.
[21:55:12] <gkamysz> to cut what
[21:55:21] <cncformywife> she need it for jewelry making.
[21:55:34] <gkamysz> what size endmills
[21:55:56] <cncformywife> like dental bits..
[21:55:59] <LeelooMinai> Probably tiny - unless it's jewelry for an elephant:)
[21:56:21] <gkamysz> ok, like 1mm or 0.1mm
[21:56:46] <cncformywife> the tip is tiny..
[21:57:27] <cncformywife> but the strait part (what go in to the collet) is 0.09 inch. 3/32
[21:57:48] <gkamysz> look at cutting tool mfg data for feed and speed
[21:57:56] <LeelooMinai> cncformywife: You could use something like proxxon rotary tool for the tool part
[21:57:57] <gkamysz> then determine how fast you need to run
[21:58:33] <gkamysz> you minimal runout to run small tools effectively
[21:58:39] <LeelooMinai> It's pretty cheap - $50 or so I think, and can do 16k rpm
[21:58:54] <LeelooMinai> Has nice bearings and small runout
[21:59:02] <cncformywife> http://www.ebay.com/itm/2014-New-Portable-Dental-Turbine-Unit-handpiece-Compressor-4H-a-/181371587801?pt=LH_DefaultDomain_0&hash=item2a3a96ccd9
[21:59:07] <cncformywife> 79$
[21:59:14] <cncformywife> 150K RPM
[21:59:14] <gkamysz> how small, collets also have small runout
[21:59:57] <XXCoder> forgot how test runout - dial indictor on bit?
[21:59:57] <LeelooMinai> I have this oneL http://www.proxxon.com/us/micromot/38472.php?list
[21:59:57] <cncformywife> what is "runout"
[22:00:02] <XXCoder> smooth part of bit?
[22:00:08] <LeelooMinai> But they have many models
[22:00:23] <gkamysz> near the collet and also at the tip
[22:00:53] <LeelooMinai> http://www.proxxon.com/us/micromot/38481.php?list
[22:00:58] <cncformywife> LeelooMinai: - it is not accurate enough!
[22:01:00] <LeelooMinai> They claim max runout 1 mil
[22:01:29] <gkamysz> so what is your machine accuracy going to be?
[22:01:38] <gkamysz> resolution?
[22:01:42] <LeelooMinai> cncformywife: You did not specify the needs
[22:01:49] <cncformywife> i need ability of 0.2 mm bit
[22:02:10] <cncformywife> with out brake it..
[22:02:11] <gkamysz> cutting metal?
[22:02:16] <LeelooMinai> cncformywife: And why do you think that rotary tool cannot handle that?
[22:02:26] <cncformywife> yes.
[22:03:13] <gkamysz> will dental turbine handle it?
[22:03:15] <LeelooMinai> You can put whatever tiny biots you have on it
[22:03:27] <cncformywife> the proxxon is not precise and too big..
[22:03:47] <cncformywife> i need 6" on 4" on 2"
[22:03:57] <LeelooMinai> Ok, but I don't understand how did you figure it's not precise...
[22:04:05] <LeelooMinai> It has only 1 mil runout
[22:04:07] <cncformywife> but precise..
[22:04:31] <cncformywife> what is "runout" ?
[22:04:53] <LeelooMinai> YOu don't know what runout is, but you know it's not precise enough - that's weird:)
[22:05:07] <gkamysz> runout needs ot be small, like 3-4 tenths max
[22:05:27] <gkamysz> .001 is huge for a 0.2mm cutter
[22:05:32] <zeeshan|2> shits gonna shatter
[22:05:35] <zeeshan|2> in a second lol
[22:05:36] <zeeshan|2> at 1 thou
[22:05:42] <XXCoder> I'm impressed with bosch at work, I hope thios bosch trim router will have very good stuff and low runout on my router
[22:05:45] <zeeshan|2> not even in a second!
[22:06:11] <XXCoder> that made me wonder. is class engravable?
[22:06:41] <gkamysz> you need a real spindle for that, something like Precise or Kavo
[22:06:53] <XXCoder> er Glass
[22:06:55] <LeelooMinai> Ok, so what is the target runout here - 5 μm or so?
[22:07:00] <zeeshan|2> XXCoder: yes it is
[22:07:09] <zeeshan|2> people use diamond tools to do that all thje time
[22:07:11] <XXCoder> delicate touch i bet
[22:07:18] <LeelooMinai> That may end up being expensive
[22:07:40] <gkamysz> yes
[22:08:10] <LeelooMinai> I iquoted that Proxxon tool because it's better then Dremel and similar brutal tools, but is still pretty cheap for hobbyist
[22:08:30] <LeelooMinai> I use it for pcb drilling
[22:08:33] <cncformywife> look here.
[22:08:35] <cncformywife> http://www.esslinger.com/tungstensteeltwistdrill.aspx
[22:08:45] <cncformywife> this are the bits.
[22:08:54] <LeelooMinai> With tiny carbide drills - some 0.3mm and it worked fine
[22:09:50] <LeelooMinai> Yes, I have somparable sized and did not break them
[22:09:57] <LeelooMinai> comparable
[22:10:17] <LeelooMinai> But I was just drilling. Not sure what would happen if you actually used mills
[22:10:23] <LeelooMinai> endmills that is
[22:11:12] <cncformywife> now she work with this
[22:11:31] <XXCoder> can always buy cheapass "engraving" chinese cnmc
[22:11:50] <XXCoder> you'd have to rebuild it since those apparently is always crappily built but parts good
[22:12:00] <cncformywife> http://www.esslinger.com/foredom-2230-flex-shaft-rotary-jewelers-kit.aspx
[22:12:02] <XXCoder> gonnma run
[22:13:02] <cncformywife> the "ebay" engraver are junk.
[22:14:55] <cncformywife> i need to machine expensive metal. and the end mill will brake and destroy the work - it will be bad
[22:15:12] <zeeshan|2> cncformywife: then you should buy a machine
[22:15:13] <zeeshan|2> lol
[22:15:33] <cncformywife> give me 20K$
[22:15:50] <zeeshan|2> you're kind of lost in how to design the machine
[22:15:51] <cncformywife> i have only 2K :-(
[22:15:52] <zeeshan|2> good luck
[22:16:22] <cncformywife> zeeshan|2: i heve an idea.
[22:16:29] <zeeshan|2> if i were you, i'd pick up a cheap chinese x-y router
[22:16:33] <zeeshan|2> replace the electronics and spindle
[22:16:37] <zeeshan|2> and it'll work decent
[22:17:10] <cncformywife> i see one of them work - for wood - fine.
[22:17:24] <zeeshan|2> yea but cutting titanium
[22:17:27] <zeeshan|2> and wood are compeltely on different levels
[22:17:31] <cncformywife> metal - forget about that.
[22:17:31] <zeeshan|2> almost uncomparable
[22:18:19] <cncformywife> and the machine itself is wobbly..
[22:18:33] <zeeshan|2> oh
[22:18:34] <LeelooMinai> cncformywife: Maybe this could do? Not CNC, but nice: http://www.proxxon.com/us/micromot/34104.php?list
[22:18:35] <zeeshan|2> then thats no good :p
[22:18:55] <zeeshan|2> cncformywife: we calculated earlier you need at most a machine
[22:19:01] <LeelooMinai> Or this: http://www.proxxon.com/us/micromot/34108.php?list
[22:19:05] <zeeshan|2> that doesnt deflect by more than 0.0003"
[22:19:11] <zeeshan|2> at a force of 40lb
[22:19:25] <zeeshan|2> you have all the parameters to know what machine to get
[22:19:26] <zeeshan|2> :P
[22:19:55] <cncformywife> how you calculate it??
[22:20:05] <zeeshan|2> we used that calculator?
[22:20:50] <zeeshan|2> if you truly want to design a machine with confidence you can go either 2 routes
[22:21:01] <zeeshan|2> 1. learn mechanics of materials and machine elements
[22:21:32] <zeeshan|2> 2. trial and error or by 'feel' and making it 3 times that size ;p
[22:22:03] <zeeshan|2> 3rd option
[22:22:12] <zeeshan|2> copy someone else's known working design
[22:22:13] <zeeshan|2> :p
[22:22:54] <zeeshan|2> LeelooMinai: how much is that micromill?
[22:22:57] <zeeshan|2> by proxxon
[22:23:09] <zeeshan|2> actually nm
[22:23:10] <LeelooMinai> I think $500 or so
[22:23:12] <zeeshan|2> the spindle speed is too slow
[22:23:16] <zeeshan|2> im looking for something of that form
[22:23:19] <zeeshan|2> but 30000 rpm spindle
[22:23:22] <cncformywife> i really impressed by the datron machine
[22:24:12] <cncformywife> but they sell expensive and big machines for what i need..
[22:24:46] <cncformywife> so, i think to "copy" datron machine but in small scale.
[22:25:35] <cncformywife> milling area of A5 size (half of A4 paper)
[22:25:57] <cncformywife> Z axis of 3-4 inch
[22:26:20] <cncformywife> so i can put mini 4 axis.
[22:28:16] <cncformywife> zeeshan|2: ?
[22:28:20] <tjtr33> unless you have better machines tools than the datron, you cannot build as good as datron. you loose in the replication. IMO i do not think you are up to it, maybe you can, but i suggest: look for used dead machines that are suitable and add a new linuxcnc control.
[22:28:49] <zeeshan|2> tjtr33: lol
[22:28:54] <zeeshan|2> you're a linuxcnc preacher!
[22:29:04] <tjtr33> sorry preach mode off
[22:29:06] <zeeshan|2> and reviver of the dead machines
[22:29:07] <cncformywife> i have linux cnc..
[22:29:09] <zeeshan|2> :-)
[22:29:54] <cncformywife> at the past i almost buy the small proxxon mini mill
[22:30:18] <cncformywife> but the lowww Z axis...
[22:30:50] <cncformywife> is too low..
[22:32:28] <cncformywife> not the X
[22:32:30] <cncformywife> the Y
[22:32:59] <cncformywife> only 1 point something, inch..
[22:33:29] <cncformywife> http://www.proxxontools.com/store/pc/viewPrd.asp?idproduct=63
[22:34:03] <LeelooMinai> 56mm
[22:34:07] <LeelooMinai> 46*
[22:34:46] <zeeshan|2> lol its 15.5 lb
[22:34:47] <zeeshan|2> cute!
[22:35:08] <cncformywife> yes.. but to small
[22:36:00] <cncformywife> if you want to make a belt for dress -opss to big or the machine..
[22:37:25] <cncformywife> for*
[22:37:47] <cncformywife> zeeshan|2: LeelooMinai https://img0.etsystatic.com/020/0/6487621/il_340x270.492865062_lz4m.jpg
[22:38:06] <cncformywife> something like this size.. even bigger.
[22:38:37] <cncformywife> but in much much higher finish..
[22:40:24] <PetefromTn_> evening folks..
[22:41:18] <cncformywife> PetefromTn_: ?
[22:42:22] <tjtr33> israel just doesnt have much in way of cnc dealers, much less a used market. look for a small deckel FP model or similar. goto a real machine shop if you can find one and look at and feel real machinery.
[22:44:01] <tjtr33> google deckel fp1 and look at the pix
[22:44:13] <cncformywife> in israel you only find big used machine... 2-3 tons..
[22:45:04] <cncformywife> tjtr33: monster!!
[22:45:24] <tjtr33> http://www.ebay.com/sch/i.html?_mPrRngCbx=1&_nkw=DECKEL+FP1+UNIVERSAL+MILLING+MACHINE
[22:45:37] <tjtr33> 4000 usd and a real machine tool
[22:46:49] <tjtr33> theres an aciera there too, better size for you, a very good machine brand for tiny stuffe
[22:49:36] <cncformywife> http://marketing.datrondynamics.com/acton/attachment/6438/6438:f-0095/0/s-0101-1406/-/l-1830/l-1830:b/
[22:49:49] <zeeshan|2> tjtr33: you're in israel?
[22:49:58] <tjtr33> nope Chicago
[22:50:10] <zeeshan|2> cause if you were, i'd say
[22:50:18] <zeeshan|2> 'can you please rob iscar and noga factories' for me
[22:50:18] <zeeshan|2> :)
[22:51:03] <cncformywife> iscar is close to my home :)
[22:52:11] <cncformywife> you can visit and get samples of defect cutting bits.
[22:53:10] <tjtr33> the used datron is for sales to US customer only
[22:54:01] <cncformywife> mmm i heve a filing..that is a bit above what i can pay..
[22:56:54] <tjtr33> haha, email from taiwan just said "please take enjoy your holiday well and funny" ( my chinese is worse, he did pretty well )
[22:57:14] <cncformywife> http://02c9c5d.netsolhost.com/images/Engraving_Stainless_Steel/Engraved_Stainless_Steel.jpg
[22:57:14] <PetefromTn_> cncformywife yeah>
[22:58:06] <tjtr33> what are those called? you make the model for a coin _huge_ , then reduce it to actual size
[22:58:10] <cncformywife> do you think i can get this quality?
[22:58:58] <cncformywife> this is a demo from datron..
[22:59:30] <cncformywife> http://02c9c5d.netsolhost.com/Engraving_Stainless_Steel.htm
[23:00:31] <cncformywife> i want to reach to the same quality, but in smaller machine..
[23:06:11] <tjtr33> granite table, fine pitch magnetic vise, 80K spindle. and a damn stiff machine. you wanna build this ? consider designing and sending the files out to be made by someone with machines like that.
[23:09:57] <tjtr33> ah yes, the master coins were 'galvanos' and were run on a 'Janvier' reducing lathe. making little coin dies from the huge master artwork
[23:10:36] <tjtr33> oops, made master hubs, that made master dies
[23:11:00] <cncformywife> tjtr33: granite table is not expensive, 80K spindle i think to use dental drill
[23:11:37] <tjtr33> dental drill have too much side play for cnc, it will break tools. dental tools are meant to held in hand, not in metal
[23:13:29] <cncformywife> and what about dremel?
[23:13:40] <tjtr33> go look at real machine tools, ask the shop owner to show you the basics. they are not 'wiggly' at all.
[23:14:08] <cncformywife> but they cost!!!!
[23:14:21] <tjtr33> hand held tool are meant to be held in hand, and the hand 'gives' and the hand 'feels' the cut. thats _not_ what cnc needs. cnc needs rigid, and exact speed control
[23:14:33] <cncformywife> and i need room for that...
[23:15:08] <cncformywife> dremel is good?
[23:15:26] <cncformywife> 175W motor :)
[23:15:45] <XXCoder> tjtr33: can alwaus do expoxy grinite
[23:15:52] <XXCoder> easy to shape and form apparenrlty
[23:16:09] <cncformywife> what is expoxy grinite??
[23:16:35] <XXCoder> manmade granite
[23:16:37] <tjtr33> and embed linear rails in it ( still precision work )
[23:16:42] <XXCoder> I cant spell worth it
[23:17:01] <cncformywife> http://www.grizzly.com/search/search?q=Granite
[23:17:08] <cncformywife> 100$ max
[23:17:16] <tjtr33> sorry, there aint no free lunch. a dead used machine is your best bet for low cost and precision
[23:17:44] <cncformywife> roland..
[23:17:49] <XXCoder> make your own for arounf $300? Large money into it but you can make a LOT stuff
[23:18:05] <XXCoder> because its large batch. you cant do smaller
[23:19:26] <cncformywife> 300$ for what purpose?
[23:19:37] <cncformywife> XXCoder: ?
[23:19:59] <XXCoder> making your own grinite
[23:20:37] <XXCoder> cncformywife: http://www.hobby-machinist.com/showthread.php?t=14217
[23:20:45] <XXCoder> it wuld make very strong and stiff base
[23:23:31] <cncformywife> what about j-b weld 2 of this
[23:23:40] <XXCoder> http://s1147.photobucket.com/user/APr3t3nd3r/media/Southbend%209in/Epoxy%20Granite/GraniteMachineBase.jpg.html
[23:24:00] <XXCoder> epoxy granite machine base
[23:24:09] <cncformywife> http://www.grizzly.com/products/9-x-12-x-3-Granite-Surface-Plate-2-Ledges/G9650
[23:24:16] <tjtr33> good stiff cheap machine DIY http://en.wikipedia.org/wiki/Multimachine
[23:25:04] <cncformywife> but how you make it precice?
[23:25:22] <tjtr33> engine blocks are precision already
[23:25:27] <XXCoder> unknown to me
[23:26:36] <cncformywife> i need 90 deg of stiff base
[23:29:23] <cncformywife> but how i put rails in the granite?
[23:31:00] <XXCoder> embed before cure I would assume. you'd have to be VERY careful not to misalign it
[23:31:23] <XXCoder> or maybe embed holes for mounting? I never tried epoxy grinite thing so dunno
[23:31:38] <cncformywife> no no..
[23:31:57] <cncformywife> in alredy make granite
[23:32:12] <XXCoder> oh tap and drill holes I guess? no idea
[23:32:14] <cncformywife> jb-weld?
[23:32:27] <XXCoder> possibly, havent heard of jb weld
[23:32:27] <LeelooMinai> double-sided tape:)
[23:32:36] <cncformywife> he he
[23:33:35] <cncformywife> you make me laugh laud..
[23:34:26] <LeelooMinai> Ok, well, I am not sure if that's viable, but maybe drilling some hole-pockets, then using epoxy to embed some metal inserts with threaded holes?
[23:35:06] <LeelooMinai> Probably with some special drills - diamond coated or who knows what (?)
[23:36:04] <tjtr33> ask Valen when he's around, he made epoxy granite head
[23:36:27] <cncformywife> i try to google it.. but cant stop laugh.. (double-sided tape)

[23:38:00] <cncformywife> he put inserts..

[23:39:22] <XXCoder> whats so annoying is that MANY cnc plans need a cnc!!
[23:39:57] <cncformywife> yep.. i hate it too
[23:40:24] <XXCoder> "first, pull a cnc out of your ass..."
[23:40:37] <cncformywife> he he...
[23:40:43] <XXCoder> "step 2: make parts for your cnc with your cnc!"
[23:40:48] <cncformywife> omg.. here is morning.
[23:41:12] <cncformywife> i make everyone wakeup..
[23:41:19] <XXCoder> 9:23 pm here
[23:41:36] <cncformywife> 7:23 Am

[23:42:51] <cncformywife> WTF?
[23:43:12] <XXCoder> its to settle epoxy grinite
[23:44:16] <cncformywife> mmm i go to my wife.. darling i need the pink stuff that you have ... it's for the cnc...
[23:44:22] <XXCoder> lol
[23:44:36] <cncformywife> http://www.vapourforge.com/cnczone/hm45/PB_Head/casting_and_releasing/casting/wife_pleaser_9000.jpg
[23:45:26] <cncformywife> i cant stop laugh
[23:45:40] <cncformywife> i have tears..
[23:46:00] <XXCoder> :)
[23:46:44] <cncformywife> what rail are good?
[23:46:59] <XXCoder> train rails
[23:47:03] <XXCoder> seriously dunno
[23:49:57] <XXCoder> this is interesying https://www.youtube.com/watch?v=yCaGW9z4blM
[23:50:21] <cncformywife> junk!
[23:50:25] <XXCoder> it is
[23:50:32] <XXCoder> but good enough for little fun
[23:51:43] <cncformywife> but junk..
[23:51:55] <XXCoder> definitely not for precision work lol
[23:52:17] <XXCoder> and wood only
[23:52:30] <cncformywife> or plastic..
[23:53:06] <cncformywife> do you think the rail from ebay are good?
[23:53:20] <XXCoder> I'm completeky wrong guy to ask
[23:54:32] <cncformywife> why?
[23:54:57] <XXCoder> not skilled in cnc besides just operating em
[23:55:07] <XXCoder> I have most parts of one cnc but have not built it yet
[23:55:59] <cncformywife> http://www.ebay.com/itm/12mm-linear-slide-guide-shaft-SBR12-330mm-2-rail-4-SBR12UU-bearing-block-CNC-set-/161194722809?pt=BI_Heavy_Equipment_Parts&hash=item2587f445f9
[23:56:16] <XXCoder> jewelery right?
[23:56:27] <cncformywife> yes..
[23:56:40] <XXCoder> 330 mm that is bit longer than a foot
[23:56:54] <cncformywife> yes..
[23:57:16] <cncformywife> but you have only half usable..
[23:57:29] <XXCoder> this seller has many better deals but expect shitty quality
[23:57:38] <XXCoder> I had to clean metal stuff out of my bearing blocks.
[23:57:53] <XXCoder> http://www.ebay.com/usr/linearmotionbearings2008?_trksid=p2047675.l2559
[23:58:57] <cncformywife> and i see THK rails..
[23:59:06] <cncformywife> what is better?
[23:59:17] <XXCoder> sbr is cheaper
[23:59:44] <cncformywife> and the sbr is presice?
[23:59:48] <XXCoder> probably less precise? but from what I see it is precise enough for some applications
