[02:01:28] <jmkasunich> I wonder what political party I'm in? I've been getting automated phone calls from both republicrats and democins
[02:08:11] <a-l-p-h-a> jmkasunich, you're independant? or just a non-voter?
[02:08:13] <a-l-p-h-a> :)
[02:08:16] <a-l-p-h-a> vote for BOTH!
[02:08:19] <a-l-p-h-a> vote twice!
[02:08:36] <SkinnypuppY34> vote=null
[02:08:36] <jmkasunich> apperently the callers don't know what party I'm in
[02:09:09] <jmkasunich> since I've gotten calls from McCain and Clinton, I guess I have to vote for the only non-spammer - Obama
[02:09:19] <SkinnypuppY34> not saying don't vote
[02:09:25] <jmkasunich> although he has a week to spam me and blow his shot at my vote
[02:09:39] <a-l-p-h-a> vote nader.
[02:11:39] <cradek> jmkasunich: at least that would even it up
[02:11:48] <jmkasunich> the spamming?
[02:12:09] <cradek> yeah then you could vote based on merit (or more likely, strategy)
[02:12:42] <jmkasunich> well, unless I get an absentee ballot right quick, I won't be voting at all
[02:12:59] <jmkasunich> businesses shouldn't be allowed to send employees out of state on election day
[02:13:11] <cradek> ouch
[02:13:38] <cradek> that would be a very interesting case
[02:13:52] <cradek> I can't go do whatever, because it's too late to vote absentee and I intend to vote
[02:14:08] <jmkasunich> I dunno when the cutoff is for "too late to vote absentee"
[02:14:42] <cradek> they sure ship you around a lot.
[02:15:00] <jmkasunich> would be interesting though - not good for the career of the person who decided to pit the constitution against the corporation
[02:15:21] <jmkasunich> my trips seem to come in bunches
[02:15:30] <jmkasunich> 2006 I traveled a LOT, 2007 not so much
[02:15:38] <jmkasunich> this will be my second trip in 2008
[02:16:00] <cradek> yay, dinner calls, BBL
[02:21:44] <a-l-p-h-a> http://weburbanist.com/2008/02/24/10-more-pieces-of-clever-transforming-furniture-from-tetris-tables-to-rooms-in-a-box/
[03:16:00] <SkinnypuppY34> Anyone know of a way to make firefox remember a sites DNS IP resolution ? My ISP dns server is being slooooow, ftp speed is great though. Lots of time " looking up whatever.com" and little time transfering.
[03:30:36] <jmkasunich> not a firefox specific thing, but I've used dnsmasq in the past - it does dns caching
[03:32:14] <jmkasunich> you running ubuntu? a synaptic search with "dns cache" finds a package for "pdnsd", a proxy dns server
[03:32:24] <jmkasunich> never used that, but it sounds like what you need
[03:33:00] <jmkasunich> (there is also a ubuntu package for dnsmasq)
[03:49:43] <SkinnypuppY34> jmk thanks! I'll try that out when I got a minute
[04:01:55] <fenn> is there a convenient way to make axis 'preview' a python gui tool before actually loading it? for example if you changed a parameter you could see it update in real time
[04:02:32] <fenn> instead of going back and opening it again
[04:43:01] <JymmmEMC> You think using a 1/6" aluminum backplane to mount all the relays, PS's, etc on is thick enough?
[04:43:06] <JymmmEMC> 1/8"
[04:43:44] <JymmmEMC> will be mounted in the four corners and maybe one in the middle, roughly 18" x 16"
[04:44:04] <JymmmEMC> inside a full tower PC case
[05:07:06] <SWPadnos_> SWPadnos_ is now known as SWPadnos
[06:36:44] <tomp> the p/s's will likely strengthen the 1/8 plate ;) seriously, the span is not so wide, which will make the plate adequate ( the .02 steel case itself is strong )
[06:40:16] <eric_U> 1/8 should be plenty thick
[12:41:34] <BigJohnT> It's Alive! http://www.youtube.com/watch?v=e70jdiDm7yc
[12:45:01] <archivist> whos a happy boy then
[12:46:15] <BigJohnT> oh me me me pick me
[12:55:01] <micges> hello
[12:55:42] <BigJohnT> hi
[12:56:19] <BigJohnT> micges: It's Alive! http://www.youtube.com/watch?v=e70jdiDm7yc
[12:59:05] <micges> what is it ?
[13:00:02] <micges> nice acc
[13:00:48] <BigJohnT> plasma cutter
[13:01:21] <BigJohnT> the X is narrow for testing in my basement
[13:04:01] <micges> very cool
[13:04:50] <BigJohnT> thanks
[13:15:38] <alex_joni> BigJohnT: don't forget to add yourself to : http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Videos
[13:21:20] <BigJohnT> ok
[13:24:07] <BigJohnT> * BigJohnT got er done now off to breakfast
[13:40:50] <tomp> BigJohnT: nice, really snappy
[13:58:39] <BigJohnT> thanks tomp
[13:58:54] <BigJohnT> bbl off to my machine shop
[14:33:37] <alex_joni> BigJohnT: stealing the wife's PC?
[14:34:24] <BigJohnT> nope
[14:34:49] <BigJohnT> I have plenty of pc's laying around
[14:55:13] <alex_joni> BigJohnT: BigJohnT [n=Miranda@] has joined #emc
[15:09:18] <BigJohnT> yes
[15:51:34] <BigJohnT> * BigJohnT trying out ProE and not liking it so far
[16:28:22] <micges> anyone can run dallur-thc config on emc ?
[16:30:05] <micges> I cant run it
[16:30:28] <micges> it shows classicladder error and hal linkage error..
[16:30:58] <alex_joni> micges: try plasma-thc
[16:31:08] <alex_joni> the dallur-thc is an older version
[16:31:26] <alex_joni> Dallur: if you find the time, could you look if we still need to keep dallur-thc?
[16:31:30] <micges> ok
[16:31:48] <alex_joni> Dallur: and if so, maybe you can make it work?
[16:33:16] <micges> plasma works fine
[17:08:35] <micges> alex_joni: who maintain configs ?
[17:09:30] <alex_joni> micges: there is no appointed responsable person
[17:09:39] <alex_joni> whoever finds something to improve .. can
[17:10:24] <micges> mhm
[17:46:32] <alex_joni> heh http://www.ibiblio.org/harris/500milemail.html
[17:56:55] <tomp> haha "3 millilightseconds"
[18:00:23] <alex_joni> * alex_joni can hear people opening up units and typing millilightseconds
[18:00:52] <alex_joni> (works here btw...)
[18:03:32] <tomp> 100 microlightseconds is 18.6 miles, now we can give local directions in unheard of units
[18:03:53] <tomp> how far to mcdonalds?
[18:04:14] <Dallur> alex_joni: we can throw dallur-thc out, the hal solution in plasma-thc is better, the only reason to keep dallur-thc would be as an example of what can be done with classicladder
[18:04:21] <archivist> one of the most obscure units i know is barn
[18:05:17] <archivist> 10 -24 sq meters which to an electron is a barn door, hence the name
[18:05:33] <tomp> will try barn, just ran nanoparsec
[18:11:48] <alex_joni> parsecs/fortnight is a very well known speed unit
[18:11:58] <alex_joni> we pondered about supporting it in g-code
[18:12:02] <alex_joni> (lol)
[20:21:07] <SWPadnos_> SWPadnos_ is now known as SWPadnos
[21:40:39] <cradek> * cradek ponders correcting archivist's mistaken definition of 'barn'
[21:41:04] <archivist> er wot
[21:41:16] <cradek> 10^-28 m^2
[21:41:19] <cradek> you said -24
[21:41:38] <archivist> about two or three years since I read about it :))
[21:42:06] <fenn> 1/avogadro?
[21:42:12] <archivist> in the section of amusing units
[21:42:23] <cradek> % units shed
[21:42:26] <cradek> Definition: 1e-24 barn = 1e-52 m^2
[21:42:41] <fenn> wait a minnit, a shed's bigger than a barn?
[21:42:48] <cradek> no, not at all
[21:42:56] <fenn> oh a barn's barn
[21:43:17] <fenn> * fenn goes back to huffing paint fumes
[21:43:37] <cradek> % units fenn
[21:43:37] <cradek> Unknown unit 'fenn'
[21:44:02] <archivist> hehe units " huffing paint fumes"
[21:44:27] <SkinnypuppY34> desparate times today?
[21:45:35] <fenn> has anyone made a collet from scratch?
[21:46:05] <SkinnypuppY34> I've made a few ER collets fenn
[21:46:06] <archivist> yes but wasnt for a lathe/mill
[21:46:46] <alex_joni> You have: shed
[21:46:46] <alex_joni> You want: barn
[21:46:46] <alex_joni> * 1e-24
[21:46:51] <fenn> SkinnypuppY34: did you measure the runout? and did you do anything exotic like grinding or nitriding?
[21:47:23] <SkinnypuppY34> Grind the rear taper and the id , no treatment though
[21:47:23] <cradek> fenn: do you need something really strange?
[21:48:06] <fenn> cradek: i have several weird collet projects actually
[21:49:42] <fenn> today i've been thinking about building one of those close quarters drills that has a gear train or timing belt driving the head
[21:50:21] <fenn> usually they have threaded adaptors that you braze onto the drill bit
[21:51:55] <fenn> so, that has nothing to do with collets..
[21:52:29] <cradek> heh
[21:52:58] <cradek> I've wondered about getting one of these for my lathe http://www.cdcotools.com/item.php?itemid=404
[21:53:15] <cradek> seems useful for all those times you want a 3-jaw that actually centers well
[21:53:17] <fenn> item 404 not found
[21:53:26] <cradek> argh their website sucks
[21:53:32] <fenn> just kidding
[21:53:39] <cradek> oh
[21:53:45] <cradek> well I had to try pretty hard to get that link :-)
[21:54:26] <fenn> Plain back, have to shoose proper back plate to connet with your machine
[21:54:48] <cradek> yeah
[21:55:12] <fenn> i blame the english technical writers for all the bad engrish out there
[21:55:34] <fenn> english-speaking
[21:55:56] <archivist> we use collets all the time, 3 jaw chucks are a poor relation
[21:56:08] <cradek> yep
[21:56:38] <archivist> collet abuse here doesnt help
[21:56:38] <SkinnypuppY34> http://engrish.com/detail.php?imagename=dont-screw-off.jpg&category=Computer&date=2003-11-07
[21:57:04] <fenn> so i suppose that thing has a boss/bore on the back for alignment? or do you hit it with a hammer until it's 'good enough'
[21:57:27] <alex_joni> omg http://engrish.com/detail.php?imagename=viao.jpg&category=Computer&date=2002-10-08
[21:58:00] <cradek> fenn: not sure. seems like you should bore a shoulder for it to fit in somehow, doesn't it
[21:59:18] <SkinnypuppY34> HSM has run an article on a backplate you can dial in tir with.
[22:00:36] <archivist> some 3 jaws have a "best" screw to tighten with (found by chance/experimentation/hammer)
[22:01:14] <fenn> drill four oversize holes in the backplate, put four dowels in the chuck, and four screws threaded into the backplate radially to push on the dowels
[22:02:01] <fenn> but i'd rather have an alignment surface
[22:02:23] <fenn> preferably a large diameter 60 degree surface
[22:03:12] <fenn> i dont get the whole precision bore/boss thing
[22:04:18] <archivist> any play/grit/dents/bumps buggers precision
[22:04:47] <fenn> you cant have any play in a tapered mounting surface
[22:05:32] <archivist> I have trouble training boss not to grip arbors in the vice, leaves marks which affect the taper
[22:05:47] <fenn> put soft jaws on your vise
[22:06:05] <cradek> archivist: or smack your boss
[22:06:05] <bill20r3> maybe you could train him by replacing the arbors on his dime.
[22:06:26] <archivist> cradek has the right idea
[22:06:32] <cradek> or get him a real holding fixture
[22:06:51] <cradek> I made one for my 30 taper tooling and never looked back - it's great to have
[22:07:04] <archivist> heh he is tooooo tight to buy any fixtures
[22:07:43] <fenn> so, why do you work for this guy again?
[22:07:54] <archivist> hehe
[22:08:10] <archivist> * archivist is always looking
[22:08:55] <archivist> jobs aren't so easy to find as you get older
[22:09:09] <cradek> shhh, don't say that
[22:09:17] <SkinnypuppY34> And there just plain aren't that many around here
[22:09:35] <fenn> i mean, clock repair is the sort of thing where you can run your own business
[22:09:54] <cradek> watches ship better
[22:09:57] <fenn> and it doesn't have to be a full time job
[22:10:27] <cradek> shipping is the key (would be for me anyway)
[22:10:30] <fenn> * fenn considers a watch a clock
[22:10:35] <cradek> maybe london is very different
[22:10:39] <archivist> thats the trouble there are too many small time clockmakers making bugger all money and a few closing down
[22:12:08] <archivist> at least the clock repairers without any kit send us work
[22:12:43] <fenn> hm. maybe you're in the wrong business
[22:12:53] <fenn> mysql consulting seems much more profitable
[22:13:26] <archivist> possibly
