[00:00:03] <zeeshan|2> lithium grease works good in general :P
[00:00:16] <Rab> Incompatible/Compatible/Borderline
[00:00:24] <PetefromTn_> I like how he setup a copper strip and probed the side shape of that vase in it.
[00:00:33] <PetefromTn_> pretty inventive
[00:00:57] <PetefromTn_> from the looks of the video of the cutting apparently the depth worked very well.
[00:02:09] <PetefromTn_> https://www.youtube.com/watch?v=9A_YlKrPDuc&list=UUKND5TJ5n3EmG8qEIizLE9Q at 1:04 you can see the program setup. WOW that is impressive work
[00:02:35] <_Sync_> PetefromTn_: using a strip of shim stock is an old trick
[00:02:46] <PetefromTn_> yeah it is
[00:03:00] <PetefromTn_> but I never saw anyone use it to probe a curved surface like that
[00:03:01] <Rab> Copper tape might give you an even better profile.
[00:03:41] <PetefromTn_> I wonder how he was able to bend the contour picture around the waist of that curved shape so that it ends where it begins
[00:03:53] <andypugh> I am pretty sure that at 1:40 (ish) he is using the self-adhesive copper tape that is sold for tiffany-style stained glass work.
[00:04:15] <_Sync_> he probably just calculates it after the shape is measured
[00:04:25] <_Sync_> the plasma is not terribly difficult to generate
[00:05:08] <PetefromTn_> very interesting.
[00:05:20] <PetefromTn_> Altho at the end of the video you can see the whole finished part
[00:05:27] <PetefromTn_> while it is exceedingly beautiful

[00:05:33] -!- linuxcnc-build has quit [Remote host closed the connection]
[00:05:40] <PetefromTn_> it is also much smaller than it appeared in the video to me
[00:06:09] <LeelooMinai> Do you have any MacGyver idea od cutting, say, 3/4 inch aluminum rod into segments with perfect parallel sides?
[00:06:16] -!- dnaleromj has quit [Quit: dnaleromj out!]
[00:06:44] <Rab> Looks like he uses a Foredom for the spindle, wonder how long that holds up.
[00:07:17] <_Sync_> does it really have to have really perfectly paralell sides?
[00:07:40] <LeelooMinai> As good as possible, yes
[00:07:48] <_Sync_> what for?
[00:08:09] <LeelooMinai> A kind of standoffs for my table
[00:08:22] <_Sync_> then it doesn't have to be as good as possible
[00:08:29] <_Sync_> just use a hacksaw
[00:08:30] <andypugh> I would part them off on a lathe.
[00:08:33] <LeelooMinai> 45 deg will not work:)
[00:08:56] <LeelooMinai> Yes, no, I am not doing it with a hacksaw
[00:09:10] <_Sync_> why not? that will be plenty good for a table leg
[00:09:21] <andypugh> But you ought to be able to square-off hacksawed sections with a counterboring bit.
[00:09:32] <Rab> LeelooMinai, use a mitre saw? The cut may not be precisely straight, but it should be reproducible from face to face.
[00:09:32] <LeelooMinai> _Sync_: cnc table, not coffee table...
[00:10:02] <_methods> cut it with a hacksaw and get out a file and make it square
[00:10:08] <_methods> first thing you learn
[00:10:12] -!- franco [franco!~franco@181.164.138.248] has joined #linuxcnc
[00:10:14] <_methods> you can do a lot with a file
[00:10:27] <LeelooMinai> That sounds like a pretty bad plan... all that work
[00:10:36] <_methods> yes
[00:10:36] <_Sync_> then just use a lathe
[00:10:39] <PetefromTn_> take it to a friend with a decent lathe.
[00:10:40] <LeelooMinai> I will probably need a lot of them
[00:10:43] <_methods> it's called skill
[00:10:49] <_Sync_> why would you stand the table off
[00:11:29] <LeelooMinai> I am not standing the table off - I have a steel thin plate and the standoffs will be on it to support t-slot parts
[00:12:13] <LeelooMinai> And screwed from the bottom - so they better be flat
[00:12:22] <LeelooMinai> And parallel
[00:12:46] <_Sync_> that doesn't sound like a serious fixturing job
[00:13:00] <Rab> LeelooMinai, why round stock instead of square?
[00:13:22] <LeelooMinai> Well, can be square - I guess that does not matter, but same problem.
[00:13:45] <_Sync_> well, henn-egg-problem
[00:13:48] <Rab> Only if you try to use the ends, instead of orienting the chunks on their sides. ^_^
[00:13:50] <LeelooMinai> _Sync_: No idea what you mean by that? :)
[00:14:14] <_Sync_> I don't know why you would use round standoffs to fixture anything to a mill
[00:14:16] <LeelooMinai> Rab: Hey, that's a good idea:)
[00:14:28] <_Sync_> that doesn't sound like it would be a very rigid setup
[00:14:46] <LeelooMinai> _Sync_: It will be poured with epoxy granite
[00:15:14] <LeelooMinai> Rab: I dont know why I did not think about it
[00:15:19] <_Sync_> > polymer concrete
[00:15:22] <PetefromTn_> what will be epoxy granite/
[00:15:23] <_Sync_> hipster
[00:15:34] <_Sync_> what's your resin content
[00:15:47] <_Sync_> and your projected E module
[00:15:50] <LeelooMinai> Didn't I talk about it yesterday...
[00:16:11] <PetefromTn_> dunno maybe I missed it
[00:16:12] -!- andypugh has quit [Quit: andypugh]
[00:16:14] <LeelooMinai> It's like it's a new channel today suddnely and all those weird questions/ideas:)
[00:16:34] <PetefromTn_> Oh it's wierd alright
[00:16:52] <LeelooMinai> It will be polyester resin and granite pebbles and sand - nothing too involved
[00:16:53] <_Sync_> if you cast them in, be sure to use helicoils, but you usually don't want the parts to index off the cast supports
[00:17:02] <_Sync_> then you might just not do it
[00:17:32] <LeelooMinai> Well, not doing it will be not very productive:)
[00:17:40] <PetefromTn_> you will probably have more money in a table made like that then if you just bought some mic6 plate and had it drilled and tapped heh
[00:17:58] <LeelooMinai> Not according to my calculations
[00:18:00] <_Sync_> because if you don't use proper filler you could just cast it out of resin completely
[00:18:07] -!- koo5 has quit [Ping timeout: 255 seconds]
[00:18:18] <LeelooMinai> I just need 1 litre resin, which is $15 and pebbles and sand, which will be additional $15
[00:18:22] -!- skunkworks [skunkworks!~chatzilla@174-124-14-116.dyn.centurytel.net] has joined #linuxcnc
[00:18:44] <LeelooMinai> mnic6 plate quoted to me was $888...
[00:18:55] <LeelooMinai> I see some price difference there
[00:18:57] <PetefromTn_> thats insane price
[00:18:59] <_Sync_> cast a test piece and measure the e mod
[00:19:02] <_Sync_> and be amazed
[00:19:14] <_Sync_> I just ordered a granite surface plate after that
[00:19:47] <LeelooMinai> _Sync_: I don;t know what you are talking about - I will have steel plate underneath it, steel reinforcments embedded, and it all will be fine for my cnc

[00:21:21] <LeelooMinai> PetefromTn_: Well, that's the price I got from metalsupermarkets here in my city
[00:21:41] <LeelooMinai> Even half of that is too much
[00:21:43] <_Sync_> if you say so, in my experience if you don't use geometry optimized filler sands it's not worth it
[00:21:58] <Tom_L> JT-Shop you still around?
[00:22:00] -!- crotchet [crotchet!~brent@168.103.46.118] has joined #linuxcnc
[00:23:01] <PetefromTn_> Well I dunno what to say that price is ludicrous
[00:23:13] <_Sync_> yeah, that's pretty steep

[00:24:35] <PetefromTn_> that is just a quick ebay search and frankly that price sucks
[00:25:19] <PetefromTn_> how did you get the material to make the rest of the machine? It's all heavy aluminum plate too isn't it?
[00:26:12] <LeelooMinai> PetefromTn_: Yes, that's US prica without shipping - I am in Canada.
[00:26:17] <LeelooMinai> price*
[00:26:27] <PetefromTn_> yup it is
[00:26:37] <PetefromTn_> surely there are suppliers in canuk land too no?
[00:26:53] <LeelooMinai> PetefromTn_: Only some parts are plate, the rest are tubes filled with sand and just wide flat bars for gantry
[00:27:19] <PetefromTn_> ok
[00:27:52] <LeelooMinai> I just used plates for z-be and small xy table bed, because otehrwise they are too expensive
[00:28:41] <PetefromTn_> well I dunno what else to say.. Good luck with whatever you decide to do.
[00:28:50] <_methods> hehe
[00:29:29] <LeelooMinai> ok, if you don't believe me:) http://i.imgur.com/Bd47EL4.png
[00:29:37] <LeelooMinai> That's only half inch and 16 by 16
[00:30:51] <_methods> hahahahhah i need to start selling aluminum in canada
[00:31:16] <PetefromTn_> Nobody said they did not believe you.
[00:31:36] <PetefromTn_> I am certain there are nefarious assholes taking advantage of people even in Canada
[00:31:38] <_methods> 1/2" x 16 x 16 for $900 that's insane
[00:31:57] <_methods> that's like home depot metal prices
[00:32:14] <PetefromTn_> Hell not even HD would try that nonsense
[00:32:47] <SpeedEvil> Maybe precision milled, TiN coated, and signed by beyonce.
[00:32:49] <LeelooMinai> Well, and you wonder why I am so obsessed with making it in some cheap way, even if a bit involved
[00:32:55] <PetefromTn_> sounds like a GO AWAY we don't want to be bothered with your small time parts nonsense to me...
[00:33:33] <LeelooMinai> They are supposed to deal with small orders
[00:33:45] <LeelooMinai> At least they advertise this way too
[00:33:51] <PetefromTn_> holy smokes...
[00:34:00] <_methods> http://www.mcmaster.com/#86825k827/=ur64f7
[00:34:09] <_methods> $124 from mcmaster lol
[00:34:17] <_methods> and that's probably %50 too high
[00:34:26] <PetefromTn_> you could buy a whole sheet for less than that...
[00:34:26] <_methods> sorry $135
[00:34:42] <SpeedEvil> PetefromTn_: whole sheet and a saw
[00:35:05] <_methods> no doubt
[00:35:21] <_methods> and a case of beer to drink while you cut it out
[00:35:34] <PetefromTn_> and pay for a cheerleader
[00:35:40] <PetefromTn_> with huge titties LOL
[00:35:49] <_methods> that taste like vanilla ice cream
[00:35:59] <PetefromTn_> ROFL
[00:36:02] <SpeedEvil> Huge titties mean she can't see where to cut the metal properly
[00:36:21] <PetefromTn_> Oh yeah she needs to be doing the cutting that is perfect!
[00:36:23] -!- Tom_L has quit []
[00:37:19] <PetefromTn_> but I digress.......the price is high....ahem
[00:38:35] * SpeedEvil wonders again how much shipping a large parcel from china would be.
[00:40:14] * PetefromTn_ didn't even know mcmaster carr sold Mic6 plate and tips his hat to methods for pointing out the obvious...!!
[00:40:35] <zeeshan|2> _methods dont sell to canada
[00:40:39] <zeeshan|2> we get metal cheap here :)
[00:40:53] <zeeshan|2> theres like 3 extruders in my town
[00:40:59] <zeeshan|2> and a couple of foundrys
[00:41:50] <SpeedEvil> yeah - you just dip a ladle into the runoff of 6061 cascading down the street.
[00:41:55] <_methods> yeah mcmaster will sell anything........for a price
[00:42:00] <_methods> not as bad as home depot
[00:42:02] <_methods> but close
[00:42:04] <zeeshan|2> mcmaster doesnt ship to residential addresses in canada
[00:42:10] <zeeshan|2> only universities and businesses
[00:42:31] <zeeshan|2> you can get that mic-6 plate locally 24x24x1/2" for $120 bux
[00:42:43] <_methods> there ya have it
[00:42:44] <PetefromTn_> there ya go...
[00:43:04] <zeeshan|2> LeelooMinai only shops at home depot
[00:43:06] <zeeshan|2> and metal supermarkets
[00:43:09] <_methods> or you can go find some sand and epoxy and make a fu mess lol
[00:43:12] <PetefromTn_> buy some for Leeloo and ship it to her house so we can see this machine running finally LOL
[00:43:18] <_methods> s/fu/fun
[00:45:02] <roycroft> do any of you use outdoor carpet to line the drawers of your toolchests?
[00:45:22] <Tom_itx> no i use rubber mat
[00:45:55] <roycroft> my kennedy uppers have felt liners
[00:46:08] <Tom_itx> mine did too
[00:46:11] <_methods> felt
[00:46:18] <roycroft> i was thinking about doing that for my kennedy roll-away, but then i started thinking about using outdoor carpet
[00:46:25] <_methods> i keep dessicant packs in mine too
[00:46:33] <roycroft> that's a good idea
[00:46:45] <roycroft> dessicant packs and liberal use of tool oil
[00:46:49] <_methods> yeah i just throw a dessicant pack i every drawer
[00:46:58] <_methods> probably overkill
[00:47:04] <PetefromTn_> I had outdoor carpet in my old tall toolbox
[00:47:06] <_methods> but i don't want rust on my mic's
[00:47:33] <SpeedEvil> ~10C of heater will help a _lot_
[00:47:41] <roycroft> any problems with rust with that, petefromtn_?
[00:48:39] -!- Tom_L [Tom_L!~Tl@unaffiliated/toml/x-013812] has joined #linuxcnc
[00:48:42] <PetefromTn_> no not really but shit and chips does get stuck in the nap
[00:48:56] <roycroft> i close the drawers when i'm operating machinery :P
[00:49:00] <SpeedEvil> I assume that there is some good reason not to use extruded sheet, ground flat?
[00:49:27] <roycroft> i have some of the perforated rubber mat in one of my roll-aways
[00:49:28] -!- Tom_L has quit [Client Quit]
[00:49:43] <roycroft> and some tools got little diamond shaped rust spots on the lower side one winter
[00:49:51] <roycroft> i did not like that
[00:50:15] <roycroft> i have some cheap rubber liners from hf in the kennedy roll-away right now
[00:50:23] <roycroft> but they're sticky, curling up, and smell chinese
[00:50:25] <roycroft> i want them gone
[00:50:42] <roycroft> i might try outdoor carpet for a season
[00:50:51] <roycroft> not glued in - just cut and set in place
[00:52:14] <_methods> cork sheet is nice too
[00:52:23] <roycroft> i've considered that
[00:52:37] <_methods> i have that in one of my boxes
[00:52:51] <roycroft> i might look at those 12" square cork tiles
[00:53:01] <roycroft> i'm not sure i can source cork sheet locally
[00:53:03] -!- [cube] has quit [Ping timeout: 244 seconds]
[00:53:04] <roycroft> but the tiles are readily available
[00:53:19] <roycroft> would the cork absorb oil though?
[00:54:41] <_methods> bah helps if you have the right board selected when you try to push program to arduino lol

[00:56:15] <SpeedEvil> http://www.ebay.co.uk/itm/All-Polished-Granite-Slabs-Tablets-Surface-plates-/261093511474?pt=UK_Measuring_Tools_Levels&var=&hash=item3cca62d132 Impressive postage.
[00:56:39] <SpeedEvil> 6.99 for a 24*32*2" plate. Of course there is the issue if by 'surface plate' they mean 'we saw other granite called surface plates, and ours looks just like it'
[00:57:17] <roycroft> if i were in the uk i would jump at that
[00:57:32] <roycroft> usually, chinese surface plates cost 2x as much to ship as the purchase price
[00:58:25] <SpeedEvil> yeah - It literally can't be fucked up enough to not be a useful machine base

[01:10:36] <XXCoder> SpeedEvil: can cnc cut it lol
[01:10:58] <tjtr33> there was another in Rockford IL for a lot less , and a lot bigger. the weeds growing around it stated something
[01:11:09] <XXCoder> tjtr33: dang. make it into cnc table. really long and biug one lol
[01:11:27] <tjtr33> was off a shaper i think
[01:12:17] <SpeedEvil> that's what - 7 tons?
[01:13:08] <SpeedEvil> Oh - I forgot to subtract the weight saving from the t-slots :)
[01:13:32] <XXCoder> probably saved so much. itt would be 6.9 tons? ;)
[01:17:35] <PetefromTn_> speaking of surface plates..
[01:18:09] <PetefromTn_> How cool would it be to buy an old huge plate and make it into one of those Datron style CNC mills....
[01:19:15] <PetefromTn_> I also see a lot of old used CMM machined that would probably be the perfect platform to build something like that on. At least the base might be.
[01:20:13] <XXCoder> any good site explaining what datron is

[01:21:54] <PetefromTn_> FAST
[01:22:21] <_methods> yeah we made a shop floor inspectio plate from an old dead cmm
[01:22:37] <PetefromTn_> you can sometimes get them pretty damn cheap
[01:23:03] <XXCoder> so it figures where stock is then make part?
[01:23:10] <PetefromTn_> If you were willing to drill and epoxy inserts into it you could probably add some linear guideways and build something really cool

[02:01:58] <_methods> running out of time before tree time
[02:02:19] <PetefromTn_> Hey man that is freakin cool!
[02:02:31] <_methods> yeah they are great fun
[02:03:08] <_methods> i need to make some more patterns
[02:03:53] <PetefromTn_> how are you controlling that?
[02:03:58] <_methods> arduino
[02:04:17] <_methods> i was using a mega for that but i'm gonna use a mini for the final thing
[02:05:04] <PetefromTn_> can you inline many 5m strips or is there load problems?
[02:05:34] <_methods> you might need to drop power supplies in there
[02:05:51] <_methods> that was 1 5m strip running off a 5v 5a power supply
[02:05:57] <_methods> 300 leds
[02:06:30] <PetefromTn_> neat
[02:07:14] <_methods> yeah you can get a 5m strip for like $50 or so
[02:07:49] <PetefromTn_> I know just bought that kit
[02:08:02] <PetefromTn_> should be here by the 29th or so apparently

[02:12:20] <_methods> yeah change the x in your settings
[02:12:26] <cradek> sure but you don't really want that. x+ moves the TOOL right (table left)
[02:12:42] <pfred1> hey cradek!
[02:12:47] <cradek> assuming you're talking about a normal vertical mill
[02:12:53] <cradek> pfred1: uh-oh
[02:13:03] <pfred1> cradek I'm using your Debian image
[02:13:08] <cradek> yay
[02:13:10] <pfred1> it's all right
[02:13:21] <pfred1> saved me a lot of time setting stuff up
[02:13:30] <pfred1> so thanks for that
[02:13:33] <cradek> welcome
[02:13:56] <pfred1> you even setup some stuff that I wouldn't have like the desktop icon and the menu entries
[02:14:01] <pfred1> they're nice
[02:14:16] <pfred1> though i do have to build a non-pae kernel one of these days
[02:14:19] <cradek> that's just in the linuxcnc package
[02:14:32] <pfred1> hmmm I never got them building from source
[02:14:33] <cradek> why?
[02:14:40] <pfred1> I just don't like pae
[02:14:44] <pfred1> too much overhead
[02:14:53] <cradek> whatevs
[02:14:56] <pfred1> I don't really need that RAM anyways
[02:15:18] <pfred1> but the latency is fine it isn't an issue
[02:15:19] <cradek> I think you'll lose the ability to run the released versions if you do that
[02:15:26] <pfred1> hmm
[02:15:33] <cradek> released packages, I mean
[02:15:46] <pfred1> should just lose RAM past about 3.5GB
[02:15:53] <pfred1> that's all pae does

[02:17:57] <jfigie> yes I just want to change the direction of x temporarily. X settings?
[02:18:23] <jfigie> I am not sure what you mean by x settings

[02:19:03] <pfred1> that'd be weird I suggest you just get used to the direction that it goes in now
[02:19:36] <jfigie> I am used to the direction I just want to test my motor because it runs smooth in one direction but not the other
[02:19:56] <pfred1> doesn't sound like softweare to me
[02:19:59] <jfigie> I want to reverse the wires on the motor and tach to see if the direction of the problem changes

[02:20:16] <Tom_itx> just change the scale
[02:20:34] <jfigie> is this in the ini file?
[02:20:36] <Tom_itx> + to - or vise versa
[02:21:48] <_methods> invert x direction in the parallel port setup
[02:22:50] <_methods> many ways to do what you want to do
[02:27:22] <jfigie> Ok I think you are telling me to change the sign in the "OUTPUT_SCALE" in the .INI file for AXIS_0, where axis 0 is the x in my case.
[02:27:30] <jfigie> Thanks
[02:28:21] <cradek> it's not a software problem - your test won't change what the hardware does

[02:29:43] <pfred1> I've been having some serious X axis hardware issues here
[02:30:00] <pfred1> I did not make my machine nearly stiff enough there at all
[02:30:14] * pfred1 has been addressing that
[02:30:44] <pfred1> one side stalled and the other kept on going and the whole machine bent up like a diamond on me
[02:30:53] <pfred1> I was like doh!
[02:31:41] <pfred1> I'm going to make some brackets out of heavy weight angle and see if that does the trick
[02:31:59] <pfred1> see if it can bend steel 3/8s of an inch thick

[02:32:26] <pfred1> oz
[02:32:46] <pfred1> I calculated the force with the threaded rod once and it isn't trivial
[02:32:54] <pfred1> something like 4 tons?
[02:33:02] <_methods> threaded rod?
[02:33:09] <pfred1> my lead screws
[02:33:21] <pfred1> they are 1/2 x 10 TPI acme
[02:34:03] <_methods> over what distance?
[02:34:15] <pfred1> what difference does distance make?
[02:34:18] <cradek> jfigie: sounds like dodgy motor brushes or tach (probably tach)
[02:34:20] <_methods> alot
[02:34:20] <pfred1> it is a pull
[02:34:48] <pfred1> the whole machine is about 3 feet wide in that direction
[02:35:00] <jfigie> ok maybe i need to rethink this. I agree this is a hardware problem so it is either the drive, the motor or the tach. Lets say the motor runs bad in the clockwise dir. If is reverse the motor leads and tach leads and the motor still runs bad clockwise then its the motor or tach otherwise its the drive.
[02:35:24] <cradek> jfigie: I have spun a tach in a drill press and scoped the output to see a dead spot
[02:35:44] <jfigie> I like that idea
[02:36:04] <cradek> you might be able to see the problem with it still in the machine
[02:36:09] <pfred1> yeah without a scope someone might as well be blind working on a lot of electronics
[02:36:13] <tjtr33> jfigie, maybe use a battery box at the drive to simplify the problem ( 2 9V batteries and a pot, the output is +/- 9V )
[02:36:21] <cradek> does it go bang bang bang once a revolution? you can probably measure it in halscope
[02:36:25] <tjtr33> no linuxcnc involved
[02:36:42] <cradek> what's it sound/feel like
[02:36:47] <jfigie> I can see the problem on hal scope looking at the error signal when I move + or -
[02:36:51] <pfred1> make a video@!
[02:36:59] <jfigie> in one direction the signal is flat.
[02:37:01] <cradek> share that pic
[02:37:18] <jfigie> the bad dir the signal has an oscillation
[02:37:25] <pfred1> my camera sucks for making videos i made one of my machine but it looks like a cartoon
[02:37:41] <jfigie> more like a sawtooth shape
[02:39:17] <jfigie> I can share but it will be a while. The machine is out in shop and turned off right now.

[03:17:45] <Connor_mill> okay pcw_home or anyone else.. what's the command to flash the 5i25? need to load it up with 5i25_7i76x2r.xml file.
[03:17:46] <LeelooMinai> I think I will go full MacGyver on this one:)
[03:17:56] <XXCoder> LeelooMinai: using unobtainable for table? heh
[03:18:16] <pfred1> if there's no baling wire it just isn't DIY CNC
[03:18:23] <XXCoder> duck tape
[03:18:37] <XXCoder> just use wood slab and tape the stock down lol
[03:18:39] <pfred1> I used some gorilla tape does that count?
[03:18:55] <XXCoder> pfred1: I use it often at work because vaccum hold sucks
[03:19:09] <pfred1> I meant to make my machine with
[03:19:18] <LeelooMinai> Well, I calculated cost of matierals for this type of configuration: http://i.imgur.com/ol7aNbx.png
[03:19:19] <XXCoder> oh lol
[03:19:37] <LeelooMinai> That is, for the t-slot type, and decided it's too much work and too much cost
[03:19:53] <pfred1> here's parts of my machine after I repainted it http://i.imgur.com/YjR9k6v.jpg
[03:20:02] <pfred1> and added steel rails
[03:20:28] <pfred1> it is the holey wonder
[03:20:40] <LeelooMinai> So, that leaves me with staggered holes, or just say 3/8 nuts so I can use that machinist clamping set in them, say every 1 inch
[03:20:57] <XXCoder> LeelooMinai: easy
[03:21:02] <XXCoder> use cnc itself to make holes
[03:21:14] <LeelooMinai> However, that would mean I would have to preset some crazy number of holes first
[03:21:27] <LeelooMinai> XXCoder: I am making it, so you know, chicken-egg:)
[03:21:36] <XXCoder> I saw one guide where guy building cnc literally cuts table with nesscary stuff with cnc
[03:21:37] <roycroft> for your initial table, get some 1/2" plate, mount it on the machine, and drill/tap 3/8" holes for the clamping system
[03:21:58] <XXCoder> LeelooMinai: yeah but since table works you can just cut it and stuff with functional cnc
[03:22:27] <LeelooMinai> Then I had this Eureka - I will just buy peg board and use it as the base of my epoxy cast and just bolt the nuts thhrough the pegboard holes:)
[03:22:30] <XXCoder> so table basically is last peice to be complete
[03:23:01] <LeelooMinai> Minimal cost and no drilling necessary
[03:23:21] <LeelooMinai> I will just need a lot of nuts and bolts
[03:23:21] <XXCoder> Yeah but then doing it with cnc also basically mean no drilling manually too
[03:23:34] <LeelooMinai> XXCoder: I don't even have a spindle yet
[03:23:37] -!- koo5 has quit [Ping timeout: 245 seconds]
[03:23:49] <XXCoder> yeah just wait on table till basically everything else is done
[03:24:09] <XXCoder> hell you can even make nut holes for other side
[03:24:17] <XXCoder> then flip it and drill holes for it
[03:24:30] <XXCoder> boom bunch of holes with nuts under all of em
[03:25:14] <LeelooMinai> I want to make table first thoug as I don't know when I will be able to afford spindle, vfd, etc.
[03:25:37] <LeelooMinai> And with the table I can try some other things - like pcb routing with rotary tool
[03:25:41] -!- Connor_mill has quit [Quit: Leaving.]
[03:26:12] <XXCoder> ahh hmm guess so
[03:26:24] <XXCoder> Im sure you can do same with rotary tool
[03:26:25] <LeelooMinai> I think it's worth a try - I don't think I can reduce the cost any more
[03:26:29] <XXCoder> I plan to use router for mine
[03:26:44] <XXCoder> one thing that sucks is min rpm 8,000
[03:26:52] <XXCoder> and not computer controlled rpm
[03:27:27] -!- Connor_mill [Connor_mill!~mill@24.214.127.194] has joined #linuxcnc
[03:27:53] <LeelooMinai> I wonder how they make holes in pegboards - if they drill them individualy on a cnc or they have something that makes them all at once
[03:28:02] <XXCoder> nah
[03:28:05] <XXCoder> press most likely
[03:28:14] <XXCoder> rolling board boom boom booom so on
[03:28:21] <LeelooMinai> But I bet they are pretty precisely spaced
[03:28:30] <XXCoder> yeah single plate for one row
[03:28:32] <LeelooMinai> So if I use them for a template I should get nice frid
[03:28:37] <LeelooMinai> grid*
[03:28:51] <pfred1> I've seen a machine that gang drills the panels for tractor trailers
[03:28:59] <pfred1> lots of pulleys
[03:29:29] <LeelooMinai> XXCoder: So like a roller with pins on it?
[03:29:55] <XXCoder> dont think so
[03:30:00] <XXCoder> more like just press
[03:30:05] <LeelooMinai> I mean like a dough roller with pins
[03:30:30] <XXCoder> HMMMM
[03:30:31] <XXCoder> http://diamondlifegear.com/pegboardsystems.htm?gclid=CPC3p6-ql8ICFUxsfgodg6kAbg
[03:30:33] <LeelooMinai> Press that does the whole grid in both dimensions?
[03:30:42] <XXCoder> metal, plastic and hardboard
[03:30:56] <XXCoder> row a time seems more likely
[03:31:27] <LeelooMinai> I think normal one from mdf will do for me
[03:32:24] <pfred1> my machine is sort of free standing so it sits on any table
[03:32:25] <LeelooMinai> I fill fasten the nuts from one side and put bolts on the other side, so that the nuts cannot be pulled out from the epoxy/granite
[03:32:49] <LeelooMinai> And later I will remove the fastening bolts
[03:32:52] <pfred1> theoretically I guess it could machine a ceiling?
[03:33:32] <pfred1> I designed it to be onmidirectional
[03:33:45] <XXCoder> 3 axis or more?
[03:33:49] <pfred1> just 3
[03:34:17] <pfred1> but the way the linears work and everything it is all symetrical
[03:34:56] <pfred1> the only up down oriented thing is the tool in the Z axis
[03:35:10] <XXCoder> nice
[03:35:18] <XXCoder> dunno who would wanna ceiling mill but cool
[03:35:25] <LeelooMinai> Hmm a 20 by 20 grid is 400 nuts - that's pretty nuts
[03:35:36] <pfred1> well I could stand it on its side to save space
[03:35:46] <LeelooMinai> Maybe I should make the grid more sparse:)
[03:35:57] <pfred1> might make loading and unloading it easier too?
[03:35:59] <XXCoder> design so nuts is movable
[03:36:05] <XXCoder> removable too
[03:36:12] <XXCoder> so you can use just few as needed
[03:36:20] <XXCoder> also makes em replacable in case of screwups
[03:36:32] <LeelooMinai> They will be embeded in the resin - I cannot make them movable
[03:36:52] <pfred1> you'll only end up using like 4 of them
[03:37:06] <pfred1> that is how things like that often go
[03:37:26] <pfred1> but the others will look nice i suppose
[03:37:42] <LeelooMinai> Well, maybe not 4, but a subset, yes, but if I need some in places they should kind of be there
[03:38:04] <LeelooMinai> I cannot predict what and where I will clamp
[03:38:19] <pfred1> maybe not but patterns will emerge
[03:38:48] <pfred1> you'll get in the habit of doingthings a certain way and that'll be that
[03:39:00] <LeelooMinai> I don't mind screwing 400 nuts since the holes in the pegboard are already there, but I wonder if it will not become too costly
[03:39:22] <XXCoder> what kinda stuff you making?
[03:39:44] <LeelooMinai> I am not making yet anything - just finishing my cnc "platform"
[03:40:03] <LeelooMinai> That is table - with very limited budget
[03:40:31] <XXCoder> what size your grid? whats closest distance nut to nut?
[03:40:56] <LeelooMinai> Table is 21 x 21 or so - pegboards seem to have 1 inch grid
[03:41:07] <XXCoder> each one inch hmm
[03:41:20] <XXCoder> wonder if can do 2 in
[03:41:35] <XXCoder> using around 2 inch clamps
[03:41:38] -!- zeitue [zeitue!~z@67.221.139.166] has joined #linuxcnc
[03:41:53] <LeelooMinai> That's an option - or I could do 1 inch in the middle and 2 on the borders
[03:42:12] <XXCoder> thats idea
[03:42:28] <XXCoder> shagger outside "square"
[03:42:35] <XXCoder> so theres always some hole near
[03:42:40] <LeelooMinai> Yes
[03:43:02] <LeelooMinai> I will do test on a small patch, say 4 by 4 inches first - I wonder how it will turn out

[03:44:54] <pfred1> sounds like a grand plan for al imited budget to me
[03:44:59] <jfigie> cradek I think my problem is the motor or tach like you suggested. http://imagebin.ca/v/1iWkM2lwHjly is running at 1440 mm/min = 24mm/sec with 2.5mm / motor rev = 9.6 Hz http://imagebin.ca/v/1iWl0MC0JOgE is 2880 mm/min and the frequency doubles. frequency is the same as the motor shaft.

[03:46:44] <cradek> scope it, and see if it makes the same voltage at the same speed in both directions
[03:47:15] <pcw_home> dirty tach brushes?
[03:47:17] <cradek> be very careful hooking up your scope - use both probes and difference mode - do not assume you can ground one side of the tach

[04:02:16] <tjtr33> both motor and tach have brushes, check the motor brushes ( remove, look for wear, clean rotor, blow out w compressed air etc) for tach, well they can be extremely tiny brushes, same is needed but if it looks to delicate, DONT ) also check connections to brushes ( often female spade )
[04:03:18] <skunkworks> the servos we are using on the K&T were originally run with SCR drives
[04:07:27] <tjtr33> the error was jitter on pid.0.error, and was directional ... is a brush so loose/worn that it cocks? and the end wear shape makes it hop?
[04:08:39] * skunkworks has never had good luck with tach..s
[04:09:22] <pfred1> scrs are usually pretty reliable
[04:09:44] <tjtr33> if its an SEM motor he oughtta be able to find the orig brush info, and check the length
[04:10:57] <tjtr33> and if he can spin the motor at a constant speed, he oughtta get a constant dc tacho voltage, not ripply like his Hal scope pix
[04:12:00] <PetefromTn_> Well I am scratching a line in the sand here guys....LOL
[04:12:18] <tjtr33> fight fight
[04:12:19] <PetefromTn_> I am gonna get the new control panel designed for the Cincinatti over the weekend or bust
[04:12:44] <Tom_itx> designed or built?
[04:12:46] <PetefromTn_> If I don't do it, it's not gonna design itself right.
[04:13:05] <PetefromTn_> well right now designed because I need to figure out what switches and stuff to order etc.
[04:13:31] <PetefromTn_> I have some leftover half inch plate 6061 that I used for a fixture I can do it out of.
[04:14:12] <PetefromTn_> I want to get the rotary selectors like we were discussing for axes selection and step selections
[04:14:19] <cradek> yikes, 1/8 is plenty
[04:14:22] <PetefromTn_> Started drawing it a bit ago.
[04:14:29] <PetefromTn_> Yeah I know but it is all I have
[04:14:30] <tjtr33> 1/2 is bezel not panel
[04:14:44] <PetefromTn_> unless I want to buy something else
[04:14:45] <cradek> and 5052 will stay shiny better
[04:15:02] <PetefromTn_> it's gonna be brushed finished
[04:15:12] <PetefromTn_> might even have it anodized or something
[04:15:29] <PetefromTn_> I should clarify
[04:15:38] <PetefromTn_> the machine already has a panel
[04:16:07] <PetefromTn_> the panel currently has the limited number of buttons I have, the MPG, and the display in it.
[04:16:26] <PetefromTn_> This panel will be JUST for the buttons and MPG and mount to the main panel under the display
[04:17:08] <tjtr33> 19" 4U panel 20$ black anodized

[04:20:35] <PetefromTn_> This is what the panel looks like now
[04:21:03] <PetefromTn_> rather that is what It looked like a couple months ago anyways LOL
[04:21:15] <tjtr33> pretty, nice work
[04:21:17] <PetefromTn_> so I am going to make a panel to go under the display
[04:21:38] <PetefromTn_> that occupies the area inside the black bezel
[04:21:40] <PetefromTn_> thanks
[04:21:47] <zeeshan|2> PetefromTn_:
[04:21:50] <PetefromTn_> its not much but it sure works nice

[04:22:27] <zeeshan|2> like that
[04:22:28] <zeeshan|2> haha
[04:22:32] <PetefromTn_> that's because all of the other pics I have posted have been from years ago
[04:22:37] <zeeshan|2> oh
[04:22:46] <zeeshan|2> your coolant
[04:22:48] <zeeshan|2> is really blue!
[04:22:51] <PetefromTn_> actually that pic is not that old
[04:23:08] <PetefromTn_> just used my old cellphone to take it which had a shitty camera
[04:23:10] <tjtr33> got 19" ? thats an industry std for control cabinets racks
[04:23:14] <zeeshan|2> PetefromTn_:
[04:23:17] <zeeshan|2> your machine is really CLEAN
[04:23:21] <PetefromTn_> no
[04:23:31] <PetefromTn_> the area I am working with is 9.25x15.5
[04:23:34] <PetefromTn_> inches
[04:23:46] <PetefromTn_> thanks man I spent a LOT of time cleaning that thing
[04:23:49] <PetefromTn_> it was FILTHY
[04:23:57] <PetefromTn_> much like my new CNC lathe
[04:24:10] <tjtr33> cut off 3.5 ;) 20$ is cheaper than your 1/2 plate
[04:24:11] <PetefromTn_> actually the Cincinatti was dirtier than the lathe initially.
[04:24:28] <PetefromTn_> yeah but I already have the plate here LOL
[04:24:34] <PetefromTn_> so it's freeeee
[04:24:51] <PetefromTn_> somebody else already paid for it :D

[04:26:24] <PetefromTn_> enjoy man
[04:26:25] <zeeshan|2> why
[04:26:34] <PetefromTn_> tooling plate rather
[04:26:41] <PetefromTn_> I have a surface plate
[04:26:47] <zeeshan|2> just mic 6 it
[04:26:52] <zeeshan|2> and drill a shit load of holes
[04:26:58] <PetefromTn_> yeah I know
[04:26:59] <zeeshan|2> but i guess that size mic6 in 1/2" or 3/4
[04:27:01] <zeeshan|2> will be stupid expensive
[04:27:10] <XXCoder> PetefromTn_: expoy granite
[04:27:11] <XXCoder> ?
[04:27:12] <PetefromTn_> would need to be at LEAST 1
[04:27:17] <PetefromTn_> 1"
[04:27:24] <zeeshan|2> so about 1000 bux
[04:27:25] <zeeshan|2> or more
[04:27:31] <PetefromTn_> yeah something like that.
[04:27:38] <zeeshan|2> XXCoder: dude
[04:27:39] <PetefromTn_> Probably at least 5-600
[04:27:41] <Connor> WooT. We have movement on the Z axis again. 150IPM stalled one time.. NO OIL on the ways or the screw.. no weight either.. was on it's back.. but.. I'll fine tune it.. also, still using the original thrust bearing vs the AC bearing..
[04:27:45] <zeeshan|2> its a cicinnati arrow

[04:27:51] <zeeshan|2> not a home made router build

[04:28:12] <zeeshan|2> epoxy granite that is
[04:28:12] <PetefromTn_> LOL
[04:28:14] <Connor> Using 5i25 + 7i76 too! :)
[04:28:23] <PetefromTn_> Connor Nice man!
[04:28:42] <Connor> I think the screw might be tad bent.. but, it's hard to say.

[04:29:15] <Connor> PetefromTn_: Yea, I dunno about that.. that guy knows his shit.
[04:29:16] <PetefromTn_> yeah he's pretty awesome

[04:29:39] <zeeshan|2> is that a gear shifter
[04:29:43] <zeeshan|2> for a mucie transmission?
[04:29:46] <zeeshan|2> er.
[04:29:46] <zeeshan|2> nm
[04:29:51] <zeeshan|2> thats a tool holder haha
[04:30:00] <zeeshan|2> wow i was so off
[04:30:11] <PetefromTn_> we need to design a swingarm toolchanger for your 0704 like he did LOL
[04:30:20] <PetefromTn_> yeah that is when I first made it.
[04:30:28] <zeeshan|2> http://s150.photobucket.com/user/matospeter/media/SAM_05602160x1620_zps030565b4.jpg.html?sort=6&o=8
[04:30:29] <PetefromTn_> It was the very first part I made on the Cincinatti
[04:30:34] <PetefromTn_> and I screwed it up LOL
[04:30:35] <zeeshan|2> thats the infamous calipers ssi and connor were talking about
[04:30:39] <zeeshan|2> carbide jaws
[04:30:40] <PetefromTn_> but it still works good
[04:30:47] <Connor> I LOVE his. Very compact.. it's not swing arm.. it's slide.. but.. it kicks butt.
[04:30:50] <zeeshan|2> are the ip65 coolant proof calipers the only ones with carbide jaws?
[04:31:03] <PetefromTn_> Connor Look again
[04:31:10] <PetefromTn_> he has a swingarm one
[04:31:20] <pfred1> zeeshan|2 this is a gear shift for a muncie http://i.kinja-img.com/gawker-media/image/upload/s--md8QWEMO--/18s43if4efx45jpg.jpg
[04:31:25] <PetefromTn_> I dunno but these are coolant proof and carbide
[04:31:41] <zeeshan|2> pfred ihave a t56
[04:31:46] <PetefromTn_> depends on the muncie
[04:31:46] <zeeshan|2> and holy cow theyre quite different
[04:31:52] <zeeshan|2> the only thing similar ar the syncros
[04:31:54] <zeeshan|2> *are
[04:32:04] <PetefromTn_> you have the T56 in that thing?
[04:32:09] <zeeshan|2> yes
[04:32:27] <zeeshan|2> i was rebuilding it and i learned that it was so similar to older t5 or tko or muncie trans
[04:32:28] <PetefromTn_> We are working on an adapter for them into the rotary
[04:32:37] <zeeshan|2> nice
[04:32:49] <PetefromTn_> six speed from viper right?
[04:32:50] <pfred1> I think i have a borg warner?
[04:32:57] <zeeshan|2> its six speed from a camaro
[04:33:01] <PetefromTn_> aah
[04:33:02] <zeeshan|2> pfred1: what car?
[04:33:09] <PetefromTn_> thats a kickass tranny
[04:33:12] <zeeshan|2> PetefromTn_: i have viper components in it
[04:33:12] <pfred1> a 1966 P1800S
[04:33:20] <PetefromTn_> cryo?
[04:33:27] <zeeshan|2> nahh
[04:33:41] <pfred1> I know i blew the lay shadt in it once
[04:33:50] <zeeshan|2> haha
[04:33:51] <PetefromTn_> Volvo?
[04:34:03] <zeeshan|2> your volve has a muncie?
[04:34:04] <pfred1> I asked the guy at the trans place did I miss the gear? he said, hell no, you sank it!
[04:34:29] <pfred1> no I think it is a borg warner
[04:34:40] <Connor> pete. I did look again.. it's a sider..
[04:34:40] <zeeshan|2> PetefromTn_: if you need any dimensions for the t56
[04:34:42] <zeeshan|2> definitely let me know
[04:34:48] <Connor> EXACTLY what I want to build.
[04:34:49] <PetefromTn_> I have the tranny here now
[04:35:04] <PetefromTn_> actually I have the mount plate from it.
[04:35:13] <zeeshan|2> bell housing?
[04:35:16] <PetefromTn_> already got a drawing going.
[04:35:17] <zeeshan|2> or front plate
[04:35:32] <zeeshan|2> http://i.imgur.com/yYu6bFG.jpg
[04:35:33] <zeeshan|2> which one
[04:35:34] <pfred1> my hot rodding days are over
[04:35:36] <zeeshan|2> aluminum or black one
[04:35:37] <PetefromTn_> well we are not using the viper bellhousing.
[04:35:44] <zeeshan|2> PetefromTn_: yea you cant
[04:35:50] <zeeshan|2> rotary bolt pattern is diff

[04:36:03] <PetefromTn_> we are using auto bellhousing from RX7
[04:36:12] <zeeshan|2> ahh
[04:36:26] <pfred1> I decided i wanted to keep it under 150 MPH
[04:36:27] <zeeshan|2> so youre making an adapter plate that goes between the bellhousing
[04:36:30] <zeeshan|2> and the trans front plate
[04:36:35] <PetefromTn_> it's kinda on hold while they save their pennies for a prototype.
[04:36:46] <PetefromTn_> yeah something like that.
[04:37:10] <zeeshan|2> just one thing that is important
[04:37:27] <zeeshan|2> the input shaft on the t56 is supported on the trans side with a taper bearing
[04:37:36] <zeeshan|2> the pilot bearing on the engine is the other support
[04:37:37] <PetefromTn_> I could make one easily but they are doing so many different things over there they can't seem to concentrate on one thing LOL
[04:37:49] <zeeshan|2> so if the trans is not concentric with the crankshaft
[04:37:56] <zeeshan|2> it owns the 4th gear
[04:37:59] -!- swingley has quit [Remote host closed the connection]
[04:38:02] <zeeshan|2> and input shaft bearing
[04:38:14] <pfred1> my car can lay out 4th
[04:38:14] <zeeshan|2> PetefromTn_: if you can make that adapter plate
[04:38:16] <PetefromTn_> yeah I know. It will be concentric if I have anything to say about it :P
[04:38:19] <zeeshan|2> you dont even need to deal with them..
[04:38:26] <zeeshan|2> you can go on rx7club.com
[04:38:29] <zeeshan|2> and sell em yourself
[04:38:33] <zeeshan|2> they'll sell like hot cakes
[04:38:37] <zeeshan|2> that is a very desired product
[04:38:38] <PetefromTn_> you think so?
[04:38:41] <zeeshan|2> yes
[04:38:48] <zeeshan|2> if you can make them for a reasonable price
[04:38:49] <PetefromTn_> freakin' tranny is expensive.
[04:39:00] <zeeshan|2> well thats their job to source
[04:39:04] <PetefromTn_> did not think too many people would want them.
[04:39:04] <zeeshan|2> you provide the component to adapt :D

[04:39:24] <zeeshan|2> you need a t56 after
[04:39:28] <PetefromTn_> it's too bad you are not rotary anymore we could work together on it.
[04:39:38] <PetefromTn_> really?
[04:39:43] <zeeshan|2> and one thing about rotary (FD RX7) crowd is
[04:39:45] <zeeshan|2> they have money
[04:39:52] <PetefromTn_> They have a bunch of cars there with a lot more than that
[04:40:00] <zeeshan|2> i had one guy return a stainless steel product i made

[04:47:25] <PetefromTn_> did you machine that base?
[04:47:29] <zeeshan|2> no
[04:47:33] <zeeshan|2> it was cheaper to get it laser cut
[04:47:35] <pfred1> it was there when I bought it

[04:49:47] <zeeshan|2> pfred1: most cars use metric bolts :P
[04:49:57] <zeeshan|2> well you said "my car has a windage tray"
[04:49:58] <pfred1> yeah most cars make me want to puke too
[04:49:59] <zeeshan|2> most cars do ! :P
[04:50:00] <PetefromTn_> I swear I know you did not like the rotary engine but those things when they are built make a sound that makes me piss my pants hehe
[04:50:15] <pfred1> well my oil pan has ears welded to it
[04:50:21] <zeeshan|2> i dont like it because its got too much maintenance
[04:50:26] <zeeshan|2> i loved the performance and sound :)
[04:50:28] <pfred1> so when you slam into a turn the oil can slosh
[04:50:39] <pfred1> most cars don't have that
[04:50:44] <zeeshan|2> oh youre talking about baffle plates
[04:50:52] <PetefromTn_> the sound is amazing really...
[04:50:52] <zeeshan|2> that are hinged
[04:50:57] <pfred1> I call it a windage tray
[04:51:05] <PetefromTn_> I never really heard a built one until I met these guys.
[04:51:06] <zeeshan|2> thats not the right term i think
[04:51:24] <zeeshan|2> http://media.caranddriver.com/images/12q4/482258/2014-chevrolet-corvette-lt1-v-8-vvt-di-oil-pan-and-windage-tray-photo-482282-s-1280x782.jpg
[04:51:26] <zeeshan|2> thats a windage tray
[04:51:28] <PetefromTn_> love the sound..

[04:52:23] <PetefromTn_> I am surprised at how many fabbers use stainless tube fittings on cars plumbing...
[04:52:28] <pfred1> solid lifters double over springs and moly rods too
[04:52:35] <zeeshan|2> PetefromTn_: stainless and aluminum!
[04:52:36] <zeeshan|2> win :D
[04:52:49] <PetefromTn_> yeah but those stainless fittings are heavy no?
[04:52:56] <zeeshan|2> depends on the fitting
[04:52:58] <PetefromTn_> they are really thick walled
[04:53:10] <zeeshan|2> if its a highly stressed part
[04:53:14] <zeeshan|2> stainless is worth it
[04:53:18] <PetefromTn_> http://i130.photobucket.com/albums/p252/turbozee84/parts-1.jpg
[04:53:20] <pfred1> for what?
[04:53:27] <pfred1> retaining heat
[04:53:35] <zeeshan|2> mechancial strength
[04:53:44] <zeeshan|2> PetefromTn_: youre right i coulda used aluminum
[04:53:46] <PetefromTn_> yeah I love stainless tubing but even my friend in Ohio who does race tuning uses them
[04:53:48] <zeeshan|2> but its much much cheaper to use stainless
[04:53:55] <zeeshan|2> how much do you think one of those bends cos tme?
[04:53:55] <PetefromTn_> really?
[04:54:00] <zeeshan|2> thats a 1.5" sch 10 elbow
[04:54:03] <pfred1> I built a stainless steel exhaust system because I got tored of doing exhaust work
[04:54:04] <zeeshan|2> 1" i mean
[04:54:07] <zeeshan|2> they were 2.50 each
[04:54:11] <zeeshan|2> when bought in a large quantity
[04:54:22] <pfred1> borla
[04:54:24] <PetefromTn_> maybe that is the main reason.
[04:54:30] <PetefromTn_> cost
[04:54:36] <zeeshan|2> stainless fittings are off the shelf
[04:54:37] <pfred1> yeah it cost me a few extra bucks
[04:54:40] <zeeshan|2> aluminum are usually custom made
[04:54:50] <PetefromTn_> you use vee bands?
[04:54:56] <zeeshan|2> for exhaust?
[04:54:57] <zeeshan|2> yea
[04:55:14] <PetefromTn_> what size turbo
[04:55:16] <zeeshan|2> theyre stupid expensive though
[04:55:17] * pfred1 is the exhaust system king!
[04:55:26] <zeeshan|2> pfred1: wanna compete?!!? :D
[04:55:30] <zeeshan|2> ps i hate exhaust work
[04:55:36] <pfred1> you should see the exhaust I built for this guy with a Chevelle
[04:55:38] <zeeshan|2> PetefromTn_: i have two t3/t04e 50 trims
[04:55:47] <PetefromTn_> ok
[04:55:55] <pfred1> with a crossover H pipe and cut outs
[04:56:15] <PetefromTn_> They just got some kinda big turbo for a build there yesterday.
[04:56:18] <pfred1> I insisted on the cross over pipe the cut outs were his idea
[04:56:25] <zeeshan|2> no X pipe? :p
[04:56:28] <PetefromTn_> ball bearing high quality one I cannot remember.
[04:56:34] <zeeshan|2> H pipe sounds so sexy
[04:56:37] <pfred1> a crossover pipe is an X pipe
[04:56:46] <PetefromTn_> not really
[04:56:47] <pfred1> but yeah it is an H not an X
[04:57:01] <zeeshan|2> gt42r?
[04:57:03] <pfred1> let me tell you with a V 8 they make a difference
[04:57:12] <pfred1> a big difference
[04:57:12] <zeeshan|2> pfred1: they make a huge difference
[04:57:17] <zeeshan|2> like 20 whp difference
[04:57:20] <zeeshan|2> on a 6.0L
[04:57:30] <zeeshan|2> hotrod did an article on this too
[04:57:31] <pfred1> yeah that car finally scared him and he got rid of it
[04:57:42] <zeeshan|2> same with header tube thickness
[04:57:45] <pfred1> after I rebuilt his carb and dropped an electronic ignition into it
[04:57:51] <zeeshan|2> 2" vs 1 1/4"
[04:57:52] <zeeshan|2> :p
[04:58:04] <pfred1> yeah he bought these really sweet glass headers for it
[04:58:09] <zeeshan|2> PetefromTn_: seriously i'd look into making parts for rx7
[04:58:10] <pfred1> they cost a fortune
[04:58:37] <pfred1> but we were making big money back then
[04:58:48] <zeeshan|2> http://i.imgur.com/RTwQW8g.jpg
[04:58:51] <zeeshan|2> thats my current setup
[04:58:56] <zeeshan|2> need to move the turbos up higher
[04:58:59] <PetefromTn_> http://i.imgur.com/iMZJd2s.jpg
[04:59:05] <zeeshan|2> PetefromTn_: rofl
[04:59:05] <pfred1> I never liked turbos much
[04:59:12] <pfred1> too low compression
[04:59:15] <zeeshan|2> pfred1: why not
[04:59:24] <PetefromTn_> BOOOOOOSSSSSSTTT!
[04:59:30] <pfred1> turbo lag
[04:59:31] <zeeshan|2> i can make 600 whp at 10 psi with the turbos i have
[04:59:33] <zeeshan|2> its a v8!
[04:59:37] <zeeshan|2> i make full boost at 1800 rpm
[04:59:47] <PetefromTn_> what is full boost?
[04:59:48] <zeeshan|2> turbo lag is on 4 bangers
[04:59:54] <pfred1> my car falls on its face anything under 3,600 RPM
[05:00:01] <zeeshan|2> PetefromTn_: the turbos are like a fan
[05:00:07] <zeeshan|2> you blow exhaust gas on them to make em spool
[05:00:07] <pfred1> dump the clutch up there though and it goes
[05:00:22] <zeeshan|2> you gotta blow a lot of exhaust gas on them before they can actually start compressing air
[05:00:33] <PetefromTn_> No I know what it means I am asking you what full boost pressure is on your setup duh
[05:00:44] <zeeshan|2> oh
[05:00:49] <zeeshan|2> i hit 16 ish
[05:00:53] <PetefromTn_> ah
[05:00:54] <zeeshan|2> on the race track
[05:00:58] <zeeshan|2> street is 10ish
[05:01:16] <zeeshan|2> pfred1: what engine?
[05:01:26] <pfred1> a 1969 B-20B
[05:01:34] <pfred1> bored 122 over
[05:01:35] <PetefromTn_> I keep hinting them I want to take a ride in the 700+hp monster RX7 they built.
[05:02:01] <zeeshan|2> 2.0L
[05:02:14] <zeeshan|2> whats 122 over
[05:02:15] <pfred1> I donno how much HP my car makes I know it is fast though
[05:02:24] <pfred1> 0.122 of an inch in diameter
[05:02:41] <pfred1> you know when peole say 40 over?
[05:02:44] <zeeshan|2> yea
[05:02:48] <zeeshan|2> thats why i asked
[05:02:50] <pfred1> yeah my engine is 122 over
[05:02:52] <zeeshan|2> thats not a common bore over size
[05:02:53] <zeeshan|2> haha
[05:03:12] <pfred1> thick casting oin the 69 blocks
[05:03:12] <zeeshan|2> dude that thing is a tank
[05:03:15] <zeeshan|2> its got a cast iron head
[05:03:15] <zeeshan|2> haha
[05:03:34] <zeeshan|2> the nice thing about cast iron heads is, they are impossible to warp
[05:03:37] <zeeshan|2> when you overheat the car
[05:03:41] <zeeshan|2> *head
[05:03:43] <pfred1> I donno aboutthat
[05:03:50] <zeeshan|2> you warped yours?
[05:03:55] <pfred1> my head is shaved down so much I worry about it
[05:04:16] <PetefromTn_> I would make parts for that car but I don't have one and not sure what they really need. Would be fun tho.
[05:04:40] <PetefromTn_> I need to try to buy one cheap and build it up hehe
[05:04:48] <PetefromTn_> excuse to buy a nice toy.
[05:05:08] <pfred1> meh for a few years I was into hot rodding
[05:05:24] <pfred1> then when I got it on the road I was like this is stupid
[05:05:44] <pfred1> so now it rots in the backyard
[05:08:30] <pfred1> http://i.imgur.com/Hh6FS3j.jpg
[05:08:41] <pfred1> those are real mags
[05:08:50] <pfred1> made out of real magnesium
[05:08:55] <pfred1> they're illegal
[05:12:25] <zeeshan|2> why
[05:12:39] <zeeshan|2> looks like a nice car
[05:12:41] <zeeshan|2> :]
[05:12:43] <zeeshan|2> drive it
[05:14:17] <XXCoder> if it ever gets on fire...
[05:14:20] <XXCoder> major fire
[05:24:25] <XXCoder> zeeshan|2: ever set magnesium on fire?
[05:24:58] <zeeshan|2> ?
[05:24:59] <zeeshan|2> yea
[05:25:05] <zeeshan|2> i work with magnesium in the metal forming lab
[05:25:07] <zeeshan|2> its not illegal
[05:25:19] <zeeshan|2> it already exists in door skins of a car
[05:25:22] <XXCoder> drat always wanted to burn one for fun
[05:25:27] <XXCoder> safely of course
[05:25:53] <zeeshan|2> the alloys im working with arent that spontaneous
[05:25:56] <XXCoder> dunno if law is illegal anywhere in usa but yeah it burns. I never said it was illegal though, pf did
[05:25:58] <zeeshan|2> real mg is supposed to react with water
[05:26:01] <zeeshan|2> this stuff barely does

[05:31:26] <pfred1> zeeshan|2 mags tend to explode
[05:31:39] <pfred1> which is why they don't make rims out of it anymore
[05:31:57] <pfred1> magnisum will shatter
[05:32:00] <zeeshan|2> what?
[05:32:06] <zeeshan|2> porsche carrera gt uses mag wheels
[05:32:17] <XXCoder> maybe different alloy?
[05:32:22] <pfred1> mag rims were banned in the 70s
[05:32:29] <XXCoder> pfred1: usa?
[05:32:30] <zeeshan|2> maybe pure mag wheels
[05:33:03] <pfred1> they're so light though
[05:33:08] <pfred1> way lighter than aluminum
[05:33:26] <XXCoder> I can't wait for day when titanium becomes cheap
[05:33:38] <XXCoder> its amazing but hard to make still :(
[05:34:18] <zeeshan|2> 0.098lb/in^3 Mg vs .063lb/in^3 Al
[05:34:32] <zeeshan|2> whoops
[05:34:34] <zeeshan|2> backwards
[05:34:44] <zeeshan|2> not that huge of a difference :P
[05:35:00] <pfred1> all I know is I've never lifted tires lighter than mine and i used to work at a tire place so I've lifted more than my fair share
[05:35:50] <pfred1> including those obnoxious no profile tires
[05:36:02] <XXCoder> alum is 1.5 times approx heavier
[05:36:07] <pfred1> we had french overarm machines for those
[05:36:08] <XXCoder> that makes heck of difference
[05:36:15] <XXCoder> assuming equal volume
[05:36:18] <zeeshan|2> 10 lb vs 15lb
[05:36:19] <zeeshan|2> big deal
[05:36:22] <zeeshan|2> its not like
[05:36:30] <zeeshan|2> steel vs al!
[05:36:32] <pfred1> it is a big deal when it is a dynamic part
[05:36:34] <XXCoder> higher rolling resistance
[05:36:45] <zeeshan|2> i much rather have something that doesnt explode
[05:36:45] <pfred1> spinning, and going up, and down
[05:36:51] <zeeshan|2> on a critical location
[05:36:52] <zeeshan|2> :)
[05:37:04] <pfred1> yeah until they exp;lode they're really nice
[05:37:27] <zeeshan|2> what worries me is we develop so much stuff for GM
[05:37:34] <zeeshan|2> metalforming techniques for magnesium
[05:37:37] <zeeshan|2> so it's making a huge comeback
[05:37:43] <zeeshan|2> so car fires in the future will be scary
[05:37:47] <pfred1> I donno how common them breaking is probably was some isolated incidents and the regulators overreacted
[05:37:48] <zeeshan|2> 2025~
[05:37:54] <pfred1> mine have never exploded on me
[05:38:43] <XXCoder> mg is making a comeback in leasy till we ever figure how to cheaply make titanium like we did with alum
[05:38:53] <XXCoder> did you know alum used to be more expensive than gold?
[05:38:59] <pfred1> I used to go to a motorcycle race and camp out and the crowd was pretty rowdy they'd burn VW engines on fires
[05:39:02] <XXCoder> thats why usa spire has alum cap
[05:39:06] <pfred1> VW engines are magnisum
[05:39:24] <pfred1> it looked ilke ET was landing
[05:39:52] <pfred1> they'd throw pots of water on the blocks while they were burning so they'd explode
[05:40:17] <pfred1> wasn't the worst thing that went on there either by a long shot
[05:40:41] <XXCoder> hear4d could leave rock in fire for hours then throw it in water body glowing red
[05:40:42] <pfred1> unafuckingdilla!
[05:40:44] <XXCoder> and it'll explode
[05:40:54] <XXCoder> insane risk though lol
[05:41:08] <pfred1> oh the day of the races peole would show up in wheelchairs
[05:41:17] <pfred1> they were fine when they got to the event
[05:41:29] <pfred1> but they were always smiling
[05:41:43] <pfred1> we were pretty nuts
[05:42:05] <pfred1> we'd burn like 7 cars
[05:42:33] <pfred1> one while it was on fire someone wrapped a chain around it and dragged into the middle of the pond
[05:42:53] <pfred1> good samaratian? I don't think so!
[05:43:11] <pfred1> it was a Camero the next day it looked like an old Ford
[05:43:26] <XXCoder> crazy
[05:43:42] <pfred1> oh i saw stuff there that was just plain silly
[05:44:14] <pfred1> one guy was lighting some kind of fireworks on the roof of his pickup and he was all drunk and he was hitting this crowd of people
[05:44:25] <pfred1> they looked up at him and said, get some aim dude!
[05:44:48] <pfred1> to this day that still strikes me as so funny
[05:45:18] <pfred1> they burned one pick up and before they set it on fire they parkeed it on this tree that was in the crotch of another tree
[05:45:34] <pfred1> so while the truck was on fire they could lever it up and throw 20lb propane cylinders under it
[05:45:53] <pfred1> when they blew up they'd lift the whole truck up about 3 feet
[05:46:10] <pfred1> of course shrapnel would come out and hit folks in the crowd too
[05:46:18] <pfred1> but that's OK right?
[05:48:16] <pfred1> that event is televised it is amazing how networks can sanatize events for broadcast
[05:48:46] <pfred1> because on TV you never saw any of what went on
[05:49:06] <pfred1> while the guys were riding peole would throw explosives on the track
[05:49:42] <pfred1> amazing races
[05:49:55] <pfred1> the 250 GP has to be seen to be believed
[05:53:11] <PetefromTn_> Damn not sure what the layout should be for the buttons..
[05:53:29] <PetefromTn_> I got the MPG and the Estop drawn in
[05:53:35] <PetefromTn_> but now I am stuck LOL
[05:54:18] <pfred1> sleep on it
[05:54:56] <PetefromTn_> heh
[05:55:03] <PetefromTn_> I need to get to sleep actually
[05:55:04] <pfred1> they say if you think about something before you go to sleep you have a better view of it when you wake up
[05:55:14] <pfred1> I htink it is true too
[05:55:39] <pfred1> like right before you go to sleep try to envision it
[05:56:43] <pfred1> then the next day you'll have lots better ideas about it all
[05:56:54] <pfred1> it works

[15:01:59] <cradek> if you checkout and build that branch, you'll get a moveoff manpage

[15:06:51] <JT-Shop> I think it was a power glitch

[15:35:56] <cradek> nope, the branch is dgarr/moveoff
[15:38:53] <lair82> It's probably not, but, is it just doing " git branch dgarr/moveoff" from the terminal?
[15:39:34] <cradek> do it the same way as you do 2.7, except it's dgarr/moveoff
[15:39:51] <cradek> you'll probably use git checkout

[15:49:18] -!- jasen has quit [Quit: Page closed]
[15:50:47] <JT-Shop> do you guys have a trick for setting the X0 on a collet holder or keyless chuck on the lathe?
[15:51:51] <_methods> do you have a tool changer or are you doing tools 1 at a time?
[15:52:17] <lair82> And that should look like this " rick@rick:~/linuxcnc-dev$ git checkout -b dgarr/moveoff origin/dgarr/moveoff " correct?
[15:52:36] <cradek> JT-Shop: I just look at it with a loupe and eyeball the center
[15:52:52] <cradek> put something stubby in it like a spotting drill
[15:53:03] <_methods> oh X
[15:53:34] <JT-Shop> ok, I'll give that a try
[15:54:04] <_methods> yeah dowel pin works good too
[15:54:13] <_methods> sorry i had mill on the brain

[15:56:33] <lair82> Ok I will give it a shot
[15:57:09] <cradek> in modern git versions I think you can just git checkout dgarr/moveoff and it'll give you a remote tracking branch like you want
[15:57:11] <PetefromTn_> Not CNC but I often use a small metal ruler to put between the tool edge and the side of a piece of round stock in the lathe
[15:57:25] <PetefromTn_> then raise or lower it until the ruler is vertical
[15:57:40] <cradek> PetefromTn_: he's mounting something like a drill chuck to the tool post and needs to center it crosswise
[15:57:50] <cradek> if I understood the question
[15:58:12] <cradek> he's got a turret
[15:59:53] <PetefromTn_> Not sure what kind of machine he has
[16:00:29] <PetefromTn_> just figured since X and Z are CNC controlled he must be talking about vertical height or center height but whaddahell do I kow LOL
[16:04:53] -!- lair82_ has quit [Quit: Page closed]
[16:05:32] <DaViruz> my lathe doesn't have a tailstock, so i often clamp drill bits directly in the tool holder. a bit cumbersome but works pretty well
[16:06:03] <DaViruz> i've been thinking about making an attachment that fits a chuck, but so far it hasn't really been worth the effort
[16:06:05] <PetefromTn_> what kind of lathe?
[16:06:17] <DaViruz> it's homebuilt
[16:06:28] <PetefromTn_> really interesting
[16:06:30] <DaViruz> bought it from a deceased dentist
[16:06:54] <DaViruz> it's really nicely made, he must have had excellent skills
[16:06:59] <JT-Shop> cradek, thanks I'll update my notes for git
[16:07:32] <PetefromTn_> pics?
[16:07:35] <JT-Shop> PetefromTn_, it's a drill chuck on the turret of my CHNC
[16:07:42] <JT-Shop> and a collet holder
[16:07:49] <lair82> Learning all the time!!!
[16:08:27] <PetefromTn_> so you are trying to find the X0 location along the cross slide travel not vertical height then.
[16:09:10] <PetefromTn_> I have seen people put a DTI in the spindle on an articulated arm and pickup the tool body before.
[16:11:41] <DaViruz> anyone know anything about this machine? http://www.blocket.se/halland/Laser_mercury_l25_57468685.htm?ca=9&w=3
[16:12:07] <DaViruz> http://laserprouk.com/ seems to be the manufacturer, but they don't really have any information on this model
[16:13:31] <DaViruz> kinda been looking at the chinese 40-60W machines, but i don't really trust them
[16:13:38] <JT-Shop> yea that's what I did too
[16:15:25] <JT-Shop> mandrel is made now to see if I can make the part
[16:16:06] <lair82> I know the guys around here use the indicator trick and run the tip around the body of whatever it is ( drill, center drill, collet body ) to establish zero.
[16:17:22] <JT-Shop> I usually put a dowel in the chuck or collet holder and indicate that
[16:17:31] <_methods> yeah
[16:17:55] <_methods> i don't really know any better ways to do it

[16:47:25] <roycroft> pandora is useless now
[16:47:36] <roycroft> there was a report on the news this morning aboutit
[16:47:39] <PetefromTn_> why
[16:47:51] <roycroft> it doesn't pick playlists based on listener preferences any more
[16:47:56] <roycroft> it picks them based on revenue
[16:48:05] <roycroft> i.e. people pay to have certain songs on pandora
[16:48:28] <roycroft> not an unexpected turn of events
[16:48:42] <PetefromTn_> well I still listen to what I want and can thumbs down what I don't like
[16:48:57] <PetefromTn_> besides I usually like what they put on there
[16:49:13] <roycroft> and i bet your thumbs downs will slowly get ignored if you diss things they want you to hear
[16:49:19] <PetefromTn_> at least in the genres of music I listen to
[16:49:26] <PetefromTn_> probably
[16:49:31] <PetefromTn_> fuckers...
[16:49:39] <roycroft> i'm a crotchety old fart
[16:49:40] <PetefromTn_> ;)
[16:49:46] <roycroft> i listen to community radio stations
[16:49:52] <roycroft> and find new music on them
[16:49:56] <roycroft> and then buy cds
[16:50:01] <roycroft> physical cds
[16:50:07] <roycroft> then i rip them and make my own playlists
[16:50:08] <PetefromTn_> my music tastes are not what I would call mainstream LOL
[16:50:14] <roycroft> so 20th century, eh?
[16:50:16] <roycroft> nor mine
[16:50:52] <PetefromTn_> I must say that I do enjoy the holiday channels they create tho
[16:51:02] <roycroft> i do, for about the first 30 seconds
[16:51:11] <PetefromTn_> nice to be able to listen to Christmas music etc without loading CD's
[16:51:12] <roycroft> which, sadly, start before halloween now
[16:51:26] <roycroft> aah, there's the key for me
[16:51:36] <roycroft> i have everything ripped and imported into itunes
[16:51:45] <roycroft> i just make playlists and stream them
[16:51:48] <PetefromTn_> I despise Itunes...
[16:51:53] <roycroft> or load them on an ipod
[16:52:04] <roycroft> there are other music library management tools besides itunes
[16:52:11] <roycroft> the point is not itunes

[16:52:17] <PetefromTn_> but I do have every piece of music I own (and that's quite a bit) ripped to my phones and laptops, computers etc.
[16:52:21] <roycroft> but that i have everything available electronically
[16:52:40] <roycroft> when i get a new cd i rip it as soon as i get it
[16:52:53] <roycroft> and most of the time that's the last time the cd is every physically played
[16:52:56] <roycroft> ever
[16:52:58] <PetefromTn_> it's a new world in music today I think...
[16:53:03] <roycroft> yes
[16:53:17] <roycroft> people either rent or steal it these days
[16:53:42] <PetefromTn_> Wonderful to have such varied music without scratched CD's or cassettes and the ability to hold massive amounts of music on a tiny device
[16:53:47] <roycroft> back in the '70s/'80s there were all those lavish rock concerts
[16:53:53] <roycroft> huge sets, huge lighting shows
[16:54:00] <roycroft> a band would put out an album and do a mega tour
[16:54:03] <roycroft> the tour would lose money
[16:54:07] <roycroft> but it would promote album sales
[16:54:15] <roycroft> now there's no money in albums
[16:54:26] <roycroft> so the band tour to make money
[16:54:39] <roycroft> with a stripped down set
[16:54:44] <PetefromTn_> no skipping, no broken or stripped tapes no nothing but good music without issues...
[16:55:03] <PetefromTn_> my kids don't know how wonderful that is really...
[16:55:13] <roycroft> i do enjoy that aspect of it a lot
[16:55:34] <roycroft> however, my main stereo is a mid '70s vintage mcintosh system
[16:55:43] <roycroft> stacked advent speakers
[16:55:51] <roycroft> and there is no remote control for it
[16:56:02] <roycroft> i have to actually get up and walk across the room to adjust the volume
[16:56:16] <roycroft> people give me crap for that all the time
[16:56:21] -!- fran_becu_ has quit [Remote host closed the connection]
[16:56:26] <PetefromTn_> that and the fact that you don't have to drive to peaches or whatever to get access to a massive array of music most of which may have never even made it to a CD LOL
[16:56:41] <roycroft> i have a lot of downloaded music
[16:56:43] <_methods> mcintosh makes great stuff
[16:56:44] <PetefromTn_> mcintosh iis good stuff
[16:56:48] <_methods> hell yeah
[16:56:49] <roycroft> another great thing about this era
[16:56:51] <_methods> i wish i had one
[16:57:02] <roycroft> yes, my '70s mcintosh system sounds better than 98% of what's being made today
[16:57:05] <ssi> I want to build another amp soon
[16:57:23] <PetefromTn_> I have a Denon system with KEF speakers here nothing fancy but it sounds good.
[16:57:29] <roycroft> i have literally thousands of live concerts that i've downloaded
[16:57:48] <roycroft> back in the '70s all we could get were scratchy, low quality bootlegs of concerts
[16:57:50] <roycroft> on vinyl
[16:57:54] <_methods> i just pick up "old" new receivers anymore
[16:58:01] <_methods> i won't spend more than $300
[16:58:05] <PetefromTn_> one thing that sucks for me is I USED to have a bunch of cool concerts on VHS... now they are unusable..
[16:58:06] <roycroft> now people are able to plug into soundboards and get perfect recordings of the concerts
[16:58:41] <_methods> i'm just too lazy to be an audiophile anymore
[16:58:44] <roycroft> some of my favorite bands are best live
[16:58:49] <PetefromTn_> let alone my Star Wars and disney tapes...
[16:59:00] <roycroft> so it's nice being able to get the live concerts so easily
[16:59:10] <PetefromTn_> Gotta get them moved to another medium or something
[16:59:59] <roycroft> i have the three "real" star wars films on dvd, but never watch them because they're the reedited versions
[17:00:05] <PetefromTn_> I am sounding pretty old here I think LOL
[17:00:16] <roycroft> a friend of mine has them on laser disk, however, and i was able to rip them from laser disk
[17:00:24] <roycroft> and those are the versions that i watch
[17:00:51] <PetefromTn_> I contacted some jackhole on craigslist that had a nice blu ray set for sale but he never got back to me...
[17:00:55] <roycroft> han shot first, and lucas cannot get away with changing that :)
[17:01:04] <_methods> hahahahhah
[17:01:17] <PetefromTn_> lol
[17:01:23] <PetefromTn_> he sure as hell did.
[17:01:30] <PetefromTn_> not sure why he wanted to change the things he did.
[17:01:36] <PetefromTn_> most of it was kinda stupid
[17:01:40] <roycroft> perhaps i'm just rationalizing
[17:02:00] <roycroft> but i feel that since i actually purchased the dvd versions, ripping my friend's laserdisk versions isn't really pirating
[17:02:08] <PetefromTn_> why did we need to have a convo with Jabba the hutt before the millenium falcon takes off?
[17:02:38] <PetefromTn_> might as well have been pizza the hutt
[17:02:47] <ssi> _methods: personally I just like building crap, and if you do a little research and are handy at building crap you can make stuff that's far better than even most "audiophile" gear
[17:03:02] <roycroft> i just hope that some day we get the original releases in true hd
[17:03:09] <PetefromTn_> that would be sweet
[17:03:10] <_methods> yeah i've made some zaph speakers
[17:03:13] <roycroft> but that will probably have to wait until lucas is dead
[17:03:22] <roycroft> although now that disney own the franchise ...
[17:03:41] <_methods> i play around alot with the class d amps too
[17:03:44] <_methods> but nothing serious
[17:03:49] <roycroft> you'd be hard pressed to build an amp as good as a mcintosh
[17:03:50] <_methods> i want to build a nice tube amp one day
[17:03:57] <ssi> _methods: https://scontent-b-dfw.xx.fbcdn.net/hphotos-prn2/t31.0-8/857195_10100298818941952_1146233300_o.jpg
[17:03:58] <roycroft> and if you could, it would probably cost as much as a mcintosh
[17:04:08] <ssi> roycroft: you'd be surprised
[17:04:24] <jthornton> yuck it is sleeting
[17:04:30] <_methods> yeah that's beautiful
[17:04:51] <_methods> i want to sexy time your tube amp
[17:04:52] <ssi> _methods: 2A3 single ended triode, 2.5W/channel
[17:05:15] <ssi> drives a pair of markaudio alpair 10p in pensil cabinets, they're 95dB/W/m
[17:05:23] <ssi> very efficient fullrange speakers
[17:06:05] <ssi> it doesn't do super bass-heavy thumpy music as well as high power stuff, but it does unbelievable things with more natural recordings
[17:06:13] <roycroft> i have a turntable too
[17:06:20] <_methods> heheheh
[17:06:22] <roycroft> a friend of mine just gave me crap about that
[17:06:58] <roycroft> he's a vet who worked around loud guns a lot, and is mostly deaf
[17:07:02] <ssi> roycroft: http://www.kbapps.com/audio/schematics/tubeamps/mcintosh/images/mc40.gif get on it
[17:07:08] <roycroft> so he can't appreciate the quality of my hifi
[17:07:22] <ssi> push-pull 6L6 isn't a particularly exotic topology
[17:07:25] <_methods> hahah i remember when i was a kid we had a galaxy 500 station wagon with an 8 track in it
[17:07:41] <Jymmm> _methods: whats changed?
[17:07:49] <roycroft> i have an mr-73, a c-28, and an mc2100
[17:07:54] <_methods> i can't get 8 tracks anymore?
[17:08:04] <Jymmm> _methods: ebay?
[17:08:09] <roycroft> the mr-73 has a vacuum tube in it
[17:08:11] <_methods> hahah probably
[17:08:16] <_methods> i've never looked
[17:08:23] <_methods> that damn car was awesome
[17:08:25] <roycroft> a "magic eye" tube - it's the last tuner mcintosh made with a tube
[17:08:29] <Jymmm> _methods: There is one on 2.5 men, so whats your excuse?
[17:08:43] <_methods> 8 track or galaxy 500 lol
[17:08:49] <Jymmm> 8track
[17:08:56] <Jymmm> the old Panasoic ones
[17:09:03] <roycroft> i should get an 8track recorder
[17:09:20] <_methods> man my mom got the beegees on 8 track and she would wear that fucker out
[17:09:21] <roycroft> maybe stick an 8track player in my vw bus
[17:09:38] <_methods> i still cringe when i hear the beegees
[17:09:42] <ssi> 8 track wasn't actually ever good :P
[17:09:51] <roycroft> doobie brothers would be better than beegees
[17:10:03] <_methods> anything is better than beegees
[17:10:05] <roycroft> but in a vw bus you would not be able to tell the difference, ssi
[17:10:05] <jthornton> I asked Ohaus for the part number of the extra weights and they gave me a quote for $50... once I had the part number Amazon $42 free shipping
[17:10:12] <ssi> probably not!

[17:58:51] <ssi> _methods: same thing
[17:58:57] <_methods> are you sure?
[17:58:58] <PetefromTn_> pics?
[17:59:08] <ssi> pretty sure?
[17:59:08] <_methods> i think the heavy 10 has a smaller spindle bore

[18:00:20] <ssi> ya
[18:00:27] <PetefromTn_> interesting.
[18:00:36] <ssi> it's 1.39" bore
[18:00:37] <PetefromTn_> At least it has a QCTP

[18:02:30] <ssi> but it's apparently fairly rare
[18:02:54] <PetefromTn_> it's funny it looks kinda small in that picture for some reason
[18:02:56] <ssi> also I'm not sure exactly what the length between centers is on this lathe, it's around 20" though
[18:03:07] <ssi> it's a "3-1/2' bed" lathe according to the placards
[18:03:15] <ssi> but that's the entire bed length
[18:03:31] <PetefromTn_> http://smg.photobucket.com/user/haplesspeanut/media/Main/EBAY10L.jpg.html
[18:03:39] <_methods> well there was a 10R, 10K and 10L i think

[18:10:46] <ssi> that's what I started with in my 2A3 amp
[18:10:49] <PetefromTn_> you were gonna build those EL84 monoblocks then?
[18:10:54] <ssi> also, 2A3 sounds better than 300B, but makes less power
[18:11:04] <ssi> 45 sounds better than 2A3, but makes even less power
[18:11:11] <ssi> yea it was on my list
[18:11:24] <PetefromTn_> that's a long freakin' list :)
[18:11:24] <ssi> but now that I don't have the transformers anymore I'm not interested
[18:11:34] <ssi> like I said, I really don't care about monoblock as a design criteria
[18:11:43] <ssi> it just means building twice as many enclosures and twice as many power supplies
[18:11:49] <ssi> including buying twice as many power transformers
[18:12:43] <ssi> and I primarily play vinyl through these amps, and it's senseless spending all that time and money on monoblocks when the channel separation of a turntable cartridge is as poor as the channel separation of a single-psu amp

[18:22:54] <ssi> they're heavy, but they're not THAT heavy
[18:23:24] <ssi> $22.41 to ship two sets of those edcor xfrms to me via ups ground
[18:23:34] <_methods> yeah i'm used to free shipping lol
[18:23:36] <ssi> what's worse than the shipping is the fact that edcor makes everything to order, so it's like four weeks lead

[18:23:51] <ssi> erg, says 6-8 weeks now
[18:23:53] <ssi> that sucks
[18:24:12] <ssi> edcor makes good stuff, but I hate waiting like that
[18:24:19] <_methods> toroidals or E type
[18:24:25] <ssi> EI
[18:24:41] <ssi> you can't really do toroidal SE output transformers
[18:24:43] <ssi> they have to be gapped
[18:24:57] <ssi> there are C core SE OTs, like the lundahls
[18:25:13] <_methods> yeah i don't know anything at all about SE
[18:25:33] <_methods> only amps i've ever messed with were D class
[18:25:40] <ssi> single ended amps are pure class A, and they're biased about halfway up the B+
[18:25:47] <ssi> which means you have current in the OT at quiescence
[18:25:54] <ssi> that makes the transformer saturate
[18:26:01] <ssi> so they have to be designed to deal with that
[18:26:07] <ssi> bigger iron and gapped cores typically
[18:26:21] <ssi> makes SE OTs more expensive per power handled/freq response than PP OTs
[18:27:23] <ssi> low end response is directly proportional to primary inductance in the OT, and primary inductance is directly proportional to the amount of copper and core in the transformer
[18:27:31] <ssi> cost and weight are directly proportional to the amount of copper and core
[18:27:40] <ssi> so low end power handling == $$$

[23:09:12] <shaun414> what do you guys think could imporve 3d printing?
[23:09:29] <cradek> 10 years
[23:09:33] <shaun414> why
[23:09:49] <andypugh> Mono-isotopic single-crystal diamond printing.
[23:09:55] <_methods> a small thermonuclear warhead?
[23:09:56] <shaun414> heh

[23:10:44] <shaun414> id agree
[23:10:47] <shaun414> death to bre
[23:10:48] <andypugh> Mine might, but yours will happen sooner.
[23:11:26] <shaun414> what can help with bed adhesion?
[23:11:27] <andypugh> Seems a little harsh.
[23:11:28] <shaun414> or speed?
[23:11:57] <andypugh> I would go for “minor discomfort to 3D Systems until they lighte up on some patents”
[23:12:58] <andypugh> 3D printing is already pretty good, if you have the right printer.
[23:13:23] <andypugh> There is a lot of difference between GGG printers and the stuff we have at work.
[23:13:40] <shaun414> heh
[23:13:53] <shaun414> im tryin to find ways to improve it
[23:14:09] <andypugh> We print 100% functional car parts, and have printers that print sand moulds for cylinder block and head castings.
[23:14:55] <andypugh> If I was to build a printer it would probably be a sand-mould printer, as I mainly want functional parts in metal.
[23:15:14] <shaun414> how would you do that
[23:15:35] <shaun414> i have an old 3d priner i kinda want to make into a cnc router
[23:15:39] <shaun414> think thats possible?
[23:15:43] <andypugh> I would shamelessly copy what the commercial printers do, and not tell them.
[23:15:55] <shaun414> true
[23:16:43] <andypugh> What do you want to rout? Foam would be OK. Tool steel might be a struggle.
[23:17:53] <shaun414> wood

[23:22:03] <shaun414> how cheap for one?
[23:22:11] <shaun414> would belt driven suck?
[23:23:03] <andypugh> I paid £700 for a 1970s “real” milling machine and about anouther £1000 on parts to CNC it.
[23:24:30] <andypugh> There are cheaper ways. Laurent Parti makes surprisingly nice parts on an all-wood machine: http://youtu.be/FXc2CcDkY5s
[23:26:59] <andypugh> And that machine seems to be all-belt
[23:27:39] <SpeedEvil> andypugh: yeah - I've been wondering about that.
[23:27:45] <SpeedEvil> Plywood is shit.
[23:27:52] <SpeedEvil> It's 1/200th as rigid as steel.
[23:28:17] <andypugh> Indeed, but he has made parts, and they look OK

[23:29:21] <SpeedEvil> But - boost the beam thickness by 3.5* and you're there
[23:30:13] <SpeedEvil> The amount of wood needed to not deflect .1mm under 100kg of cutting force over a 1m span isn't really that high
[23:30:20] <andypugh> MDF has a modulus of 4GPa, and Steel is 200, so it’s not quite as bad as you say
[23:30:48] <SpeedEvil> yeah - I was basing measurements of this really really shitty plywood I've gotten, probably in the bendy direction
[23:31:15] <SpeedEvil> Properly treated decent wood gets rather better
[23:31:23] <SpeedEvil> thermally treated wood has interesting properties
[23:31:26] <SpeedEvil> but is more complex
[23:32:12] <andypugh> Oak is 11, aluminium is 69. I imagine solid hardwood approaches extruded Aluminium section for stiffness.
