[00:50:09] <sharpen047> what are zero helix end mills usually used to cut?
[00:55:10] <Tom_itx> dunno
[00:55:25] <Tom_itx> chamfer the end and you have a reamer though :)
[00:56:04] <Tom_itx> we used half round drill bits in brass
[00:56:14] <Tom_itx> no helix

[02:33:30] <jdh> so, pick it up
[02:34:06] <PetefromTn> kay, anybody making anything interesting on your CNC machines?
[02:34:52] <PetefromTn> I am sitting here trying to come up with something cool to make on mine so I can continue to get a feel for how it likes to be run.
[02:36:24] <PetefromTn> also gotta machine some hold down clamps for the CNC vise so I can take back my hold down kit parts.
[02:36:45] <Tom_itx> make a sacrificial plate for it
[02:36:52] <Tom_itx> with a grid of tapped holes
[02:37:19] <PetefromTn> Not a bad idea but I can't tap just yet still need the encoder on the spindle for that.
[02:37:41] <jdh> I thought you had an encoder
[02:37:47] <jdh> and a prox switch
[02:38:05] <PetefromTn> I do have one just have not gotten it installed yet as I need a custom mount for the top of the spindle motor.
[02:38:39] <PetefromTn> the machine has several prox switches on the spindle for different functions
[02:38:51] -!- fiesh [fiesh!~fiesh@p4FCB5B1C.dip0.t-ipconnect.de] has joined #linuxcnc
[02:39:08] <PetefromTn> it has tool clamp and unclamp, 180 out sensor, and something else..
[02:39:18] <PetefromTn> there's like four of them there.
[02:39:54] <Tom_itx> that's why i'm looking at single profile thread mills
[02:40:12] -!- cradek has quit [Read error: Connection reset by peer]
[02:40:20] -!- cradek [cradek!~chris@outpost.timeguy.com] has joined #linuxcnc
[02:40:21] <PetefromTn> That is what I want to get too, Nice to be able to do multiple threads with one tool.
[02:40:40] <Tom_itx> i've got no reverse on my spindle yet
[02:40:46] <Tom_itx> or index encoder
[02:41:08] <PetefromTn> I've got reverse so I could actually use a floating head right now.
[02:41:20] <PetefromTn> That is how I tapped with my Rf45 CNC
[02:42:03] <PetefromTn> Honestly I would love to fabricate a simpler spindle feedback setup that would not need the 180 out sensor and the associated circuitry.
[02:42:16] -!- KGB-linuxcnc has quit [Ping timeout: 246 seconds]
[02:44:21] <PetefromTn> so nobody making anything cool?
[02:45:18] <jdh> not me.
[02:45:28] <PetefromTn> I'm sorry..
[02:45:46] <jdh> me too.
[02:45:54] <PetefromTn> are ya making ANYTHING?
[02:45:57] <jdh> work and crap get in the way
[02:46:23] <PetefromTn> for me crap gets in the way, I'd welcome the work LOL.
[02:46:24] <jdh> spent thursday-sunday going to TN for a wedding. Made a lot of gas stations happy
[02:46:36] <PetefromTn> Oh yeah where in TN?
[02:46:42] <jdh> Nashville
[02:46:46] <PetefromTn> Aah.
[02:49:28] <PetefromTn> You know you got it bad when you search google for CNC machining ideas LOL.
[02:59:55] <skunkworks> nothing you need for the fiero?
[03:00:11] <pcw_home> PetefromTn: it _should_ be possible to use the index mask facility thats built into the hardware But I dont know if its been tried, worst case you will have to upgrade to master after a patch has been made
[03:00:35] <pcw_home> thats the cleanest way (no external hardware)
[03:01:15] <cradek> I use encoder mask on my hnc
[03:01:40] <cradek> it has like 10 indexes per screw turn and a prox on the pulley selects just one
[03:01:43] <PetefromTn> LOL yeah my fiero, honestly it is not running that good yet. I bought it running crappy and fixed a bunch of stuff with it but have not gotten it sorted yet. I did used to make some engravings for the fiero folks for sale but my macines spindle is only good for 6k so I need to fab up some sorta higher speed spindle before I can go back to making them.
[03:01:54] <cradek> it has worked for years, nothing new about it
[03:02:05] <cradek> index mask I mean, of course
[03:02:55] <pcw_home> Well not sure if muxed index mask works
[03:02:56] <PetefromTn> pcw_home Yeah I have heard it has the feature but we spoke about it before and Connor had been under the impression it was something that could only be accomplished with a small board and some sorta chip.
[03:03:08] <cradek> ah
[03:03:21] <cradek> yeah this is the old 7i33/5i20 combo
[03:03:37] <PetefromTn> I've got the 5i25/7i77...
[03:03:57] <PetefromTn> It would sure be nice if it would work in software.
[03:04:10] <pcw_home> It may need a driver tweak, I dont think the MIM option has been tried
[03:04:33] <PetefromTn> I purchased the differential encoder over the single ended because I needed the line driver.
[03:04:40] <PetefromTn> What is muxed?
[03:04:43] <pcw_home> The demux hardware has been in the firmware for years
[03:05:46] <pcw_home> the 6 encoders on the 7I77 are multiplexed (they would need 18 wires out of he 17 available otherwise)
[03:06:13] <pcw_home> s/ he/the/
[03:07:43] <PetefromTn> I am sorry but I just don't understand that. Remember I am not Connor the guru here LOL.
[03:08:27] <pcw_home> so the firmware sends the even encoder signals(0,2,4) alternately with the odd encoder signals (1,3,5)
[03:08:29] <pcw_home> on the same 9 wires
[03:08:55] -!- kmrhb has quit [Ping timeout: 264 seconds]
[03:09:35] <PetefromTn> this is the differential function then?
[03:10:07] <Connor> Someone say may name?
[03:10:28] <pcw_home> No, this is how the signals get crammed onto the 17 wires available on the DB25 interface
[03:10:46] <PetefromTn> oh okay.
[03:11:01] <PetefromTn> thats the mesa magic..
[03:11:17] <PetefromTn> Connor Yeah I guess I did LOL.
[03:11:36] <pcw_home> well multiplexing dates from telegraph days
[03:11:55] <PetefromTn> and modest too...
[03:12:06] <PetefromTn> so what is muxed?
[03:12:36] <Connor> PetefromTn: Taking multiple inputs and reducing them to down to a smaller amount.
[03:13:01] <PetefromTn> so basically that is what he was talking about which went over my head basically.
[03:13:04] <Connor> pcw_home: I was going to use a opto-coupler to mux the index + 180 out sensor.
[03:13:28] <Connor> pcw_home: I think we talked about how to do it a while back.
[03:13:45] -!- Valen has quit [Quit: Leaving.]
[03:14:34] <Connor> cradek: I have him running on 2.6.x code base.. if that's what you meant by upgrading him to master.
[03:15:40] <pcw_home> I mentioned to PetefromTn that it might be worth trying the built in hardware
[03:15:42] <pcw_home> though it may need a driver tweak. This has the advantage that no external hardware is needed
[03:15:44] <pcw_home> (as long as a TTL or differential mask signal is available)
[03:16:20] <Connor> It's a 24v proximity sensor.
[03:16:33] <PetefromTn> I think it is anyways..
[03:16:46] <PetefromTn> Have not checked it so far. Probably is tho...
[03:16:53] <Connor> PetefromTn: It is.. Lee confirmed it for me. and he's told me what wires are what.
[03:17:11] <pcw_home> Oh that makes it interesting (and so probably requires external hardware anyway)
[03:17:27] <PetefromTn> REALLY!! excellent. He helped me with something else earlier today.
[03:18:55] <PetefromTn> Connor Milled some steel today! Machine cut great man.
[03:19:04] <PetefromTn> in HRS no less.
[03:19:04] <Connor> Great!
[03:19:12] <Connor> HRS ?
[03:19:20] <ssi> he's right though, Mach3 is in a different class
[03:19:21] <PetefromTn> Yeah Hot rolled steel tubing
[03:19:24] <ssi> whoa
[03:19:44] <ssi> sry that was in my up arrow history from a week ago :P
[03:19:46] <PetefromTn> ssi hey man whazzup.
[03:19:53] <ssi> just got home from san fran
[03:20:02] <ssi> long day of traveling
[03:20:05] <PetefromTn> was wondering what happened to ya.
[03:20:09] <pcw_home> so the prox (on spindle) generates a ~180 degree mask?
[03:20:13] <ssi> yea I had to get out for a couple days :)
[03:20:37] <PetefromTn> pcw_home Yeah there is a half moon protrusion on the spindle body that the sensor picks up.
[03:20:54] <PetefromTn> I was just in San Fran a couple months ago.
[03:21:04] <PetefromTn> Love the fishermans wharf.
[03:21:43] <ssi> I didn't go into the city... spent most of my time in the valley
[03:21:52] <ssi> went up to muir woods and stinson beach yesterday
[03:22:05] <eric_unterhause1> sounds nice
[03:22:19] <PetefromTn> My wife and I used to ride my sportbike down the PCH and stay in Stinson Beach. Cool place.
[03:22:28] <eric_unterhause1> although we have some really nice woods out behind my house
[03:22:59] <Connor> ssi: Got the pulleys Friday. Will coordinate with pete for getting them bored out and turned correctly.
[03:23:05] <ssi> Connor: awesome, thanks :DH
[03:23:16] <ssi> I got my servo power supply and mesa gear in the mail while I was gone
[03:23:22] <PetefromTn> What does DH mean?
[03:23:33] <ssi> it means :D, plus an extra additional keystroke
[03:23:42] <PetefromTn> LOL
[03:23:42] <ssi> my typing fingers are out of practice
[03:23:58] <Connor> I get a smiley face graphic on my end. :)
[03:24:27] <PetefromTn> I was thinking of designing a cool looking mount for my keyboard tray to go beneath the pendant as a test project run.
[03:24:36] <Connor> PetefromTn: You find anything that can work as a lift plate?
[03:24:43] <ssi> PetefromTn: were you able to do anything with taht protram model?
[03:25:03] <PetefromTn> I need something that will allow me to tilt it and lock it in place.
[03:25:24] <PetefromTn> ssi No not yet, been working on the machine and trying to get these parts machined for a customer.
[03:25:29] <PetefromTn> Got it done this afternoon.
[03:25:35] <ssi> cool
[03:26:04] <PetefromTn> Not sure when I will machine that part and I apparently have to mod it so there is two spots for the grub screw right?
[03:27:06] <Connor> What? The protram ?
[03:27:11] <PetefromTn> yeah..
[03:27:25] <ssi> oh was that still missing?
[03:27:26] <ssi> I'm sorry
[03:27:28] <ssi> I can fix that
[03:27:38] <PetefromTn> no worries man. I can do it.
[03:27:48] <ssi> it was in the model, just suppressed for some reason
[03:28:18] <PetefromTn> honestly my 3d cad cam skills are rudimentary at best so it may be just a setting.
[03:28:35] <PetefromTn> I'll monkey with it after I get some other stuff done I need to do.
[03:28:44] <PetefromTn> I do appreciate the model tho man thanks.
[03:28:47] <ssi> sure thing
[03:28:50] <ssi> it was fun to draw
[03:29:29] <PetefromTn> Been sitting here racking my brain trying to come up with an uber cool product to make and start selling. Nothing jumping out at me yet.
[03:30:23] <PetefromTn> Gotta start making some parts and selling stuff so my wife does not think this whole mess was just a goof LOL.
[03:30:56] <PetefromTn> Anyone else cannot get on the CNCzone?

[10:47:52] -!- stsydow has quit [Quit: Leaving]
[10:49:24] <toastydeath> the tip for buying a used cnc like that is two fold
[10:49:37] <toastydeath> one, pick a very popular, high end brand - of which Mazak is one.
[10:49:53] <toastydeath> second, pick a machine that is popular and not low end. Mazak made some low end machines.
[10:49:57] -!- mhaberler [mhaberler!~mhaberler@macbook.stiwoll.mah.priv.at] has joined #linuxcnc
[10:50:12] <toastydeath> if you got a high end Mazak, it's unlikely to be all that shitty.
[10:50:34] <toastydeath> I used a OKK at work from 1960 and it was really nice.
[10:50:53] <toastydeath> ballscrews the size of my arm, and the box way was literally 3 feet wide.
[10:51:04] <toastydeath> (which was bigger than the table it supporteD)
[10:51:32] <toastydeath> a machine like that is more likely to be in good condition even if it was beat on than a shittier machine that hasn't been used all that roughly
[10:51:52] <toastydeath> i don't know if that particular model of mazak is one of their better ones
[10:52:45] <toastydeath> also, a geared head, plain way machine is going to be more survivable than a direct drive, linear way machine - if you have the option.
[10:54:12] <RyanS> hmm do high end CNC machines now use the screws that are the next step up from ballscrews (I can't remember what they are called)
[10:54:22] <toastydeath> no
[10:54:28] <RyanS> Worm drive leads screws..
[10:54:52] <toastydeath> ballscrews are still the standard, some machines obviously use some other technology
[10:55:07] -!- sivoais has quit [Ping timeout: 264 seconds]
[10:55:12] <toastydeath> the general jump goes from ballscrew to linear motor, not to the more esoteric drives
[10:55:20] <toastydeath> and linear motors are for smaller, faster machines
[10:55:47] <RyanS> And trains :)
[10:56:02] <RyanS> While it's sort of magnetic levitation
[10:56:22] <toastydeath> to be honest, your best bet is probably to get a used mori seiki mill
[10:56:31] <toastydeath> they're very high end, and are prolific
[10:57:00] <toastydeath> the boards and shit for their controls are expensive (1k-2k usd) but don't break all that often and are available
[10:57:31] <RyanS> I'm not in the market...... just curious bystander
[10:57:31] -!- ds3 has quit [Ping timeout: 252 seconds]
[10:59:06] <toastydeath> mori seiki, kitamura, matsurra, etc all served the high end of the market in the 80s and not the low end, so those machines are the ones I'd personally look at
[10:59:20] <toastydeath> Mazak served everyone and so is more hit or miss
[10:59:32] <RyanS> are haas cheapo ? They look pretty average on the surface anyway....
[10:59:40] <toastydeath> haas is low end, yeah.
[10:59:49] <toastydeath> they're on part with any of the modern no-name import brands
[10:59:52] <toastydeath> *on par
[11:00:42] -!- ds3 [ds3!noinf@netblock-66-245-251-24.dslextreme.com] has joined #linuxcnc
[11:00:50] <toastydeath> their controls are also shitty
[11:01:00] <RyanS> I thought there are some pretty high hand machines from Taiwan these days?
[11:01:06] <toastydeath> sure
[11:01:22] <toastydeath> "no name" import, not "high end, name brand machine from taiwan or japan"
[11:01:43] <toastydeath> there are machine builders who buy stock parts (castings, etc) and assemble machines piecemeal
[11:02:09] <toastydeath> and so the machines are a hodgepodge of off the shelf parts
[11:02:19] <toastydeath> nothing wrong with that, but they're not super high quality
[11:02:39] <toastydeath> I am actually a fan of small lathes built that way
[11:03:16] <toastydeath> we had a few 8x20" lathes that weighed about 4 tons each, fast spindles and more than enough power for their size
[11:03:40] <RyanS> Brand I have seen is Mitseki, apparently they are a Taiwanese OEM that builds machines for some of the big names
[11:03:56] <toastydeath> because the parts are off the shelf, it's cheaper to just buy the same motor, same turret, same spindle, etc across a bunch of machine sizes
[11:04:10] <toastydeath> so you get a wildly overbuilt small lathe, but as the size goes up it becomes shitty
[11:04:24] <RyanS> ah
[11:04:43] -!- sivoais has quit [Ping timeout: 264 seconds]
[11:04:53] <toastydeath> also I think chinese brands are going to be the folks to watch
[11:06:00] <RyanS> They are the world's second biggest economy is I don't see why manufacturing quality isn't going to increase
[11:06:21] <toastydeath> my suspicion is that they've got some very high quality machines but they just don't export
[11:07:20] <RyanS> Probably.. Unless manufacturers of high quality parts are using Japanese machines
[11:07:36] <toastydeath> china doesn't like importing manufacturing equipment
[11:08:01] <toastydeath> my understanding is that if you want to import a machine, you have to prove that you can't find something rougly equivalent in-country
[11:08:02] <RyanS> Not economical perhaps...
[11:08:40] <RyanS> oh the government mandates it
[11:08:53] <toastydeath> yeah
[11:08:57] <RyanS> To boost the local manufacturer perhaps?
[11:09:16] <toastydeath> well, it keeps that economic sector strong because it eliminates outside influence
[11:10:14] <toastydeath> the flow of capital becomes a closed loop
[11:10:26] <toastydeath> rather than what the US did
[11:11:01] <RyanS> Protectionism... The US does it with agriculture that's about it
[11:12:43] <RyanS> in Australia manufacturing is like 100 times more profitable for less resources than agriculture
[11:14:09] -!- sivoais has quit [Ping timeout: 248 seconds]
[11:16:08] <RyanS> you think the "3-D printing revolution" bandied about in the media is over optimistic? It doesn't seem much like a revolution to me
[11:20:37] <toastydeath> super optimistic
[11:21:09] <toastydeath> look around you and think about how much stuff you own that is JUST plastic.
[11:21:14] <toastydeath> no other parts whatsoever
[11:21:27] <toastydeath> it'll get there someday, but not this decade.
[11:22:12] <RyanS> But there are a lot of things but simply can't be only plastic
[11:22:27] <toastydeath> that's what i'm saying
[11:22:41] <toastydeath> but they're working on printing things like traces
[11:22:44] <toastydeath> and some pick/place stuff
[11:22:50] <RyanS> Okay I get you
[11:23:19] <toastydeath> i am personally optimistic about it because i think it will usher in some philosophical changes as well as changes in manufacturing
[11:23:40] -!- sivoais has quit [Ping timeout: 252 seconds]
[11:23:41] <toastydeath> it's a wonderfully good thing, but the media has shown very little interest in understanding anything with nuance
[11:25:10] <RyanS> DMLS is the only process that can print metal as far as I know.. And very expensive
[11:25:42] <toastydeath> they might try printing thermoset resins with a low melting temp alloy
[11:26:05] <toastydeath> i know it's not possible now, but I think the possibilities are too enticing for smart people not to work on it
[11:26:28] <toastydeath> or hey, a conductive thermoplastic.
[11:26:45] <gonzo_> the only advantage I can see 3d printing gives is that it saves the need for an injection mould. But for small runs/prototypes, there is a little known technique called milling !
[11:27:05] <toastydeath> a 3d printer can make things that are hard to mill
[11:27:28] <toastydeath> you can also make things like moulds for metal casting, which brings the cost of one-off cast parts down
[11:27:32] <RyanS> True however can you see it ever replacing injection moulding for manufacturing?
[11:27:47] <toastydeath> i've never thought that 3d printing will replace anything
[11:27:51] <toastydeath> any more than a milling machine replaces a lathe
[11:27:57] <gonzo_> that is true, but the people who seem to be pushing this are not engineers
[11:28:26] <toastydeath> sure, they're overly optimistic computer science people who have never been involved in manufacturing
[11:28:43] <toastydeath> like anything that group gets involved with, they'll be wrong and then people who know what they're doing will start to use it
[11:29:07] <RyanS> I think 3-D printing is more of of an evolution of already existing processes it just makes prototyping faster
[11:29:13] <toastydeath> yep
[11:29:25] <gonzo_> Yep, I hear it all the time at work. Mainly be people who do not even own a set of spanners
[11:29:43] <toastydeath> i think it WILL evolve to a point where some classes of parts are made entirely by 3d printing on an as-needed basis
[11:30:00] <toastydeath> I would print vice jaws, for example.
[11:30:13] <toastydeath> for holding delicate parts or things at an odd angle.
[11:30:33] <toastydeath> you could print the human-interfaced part of proesthetics
[11:30:47] <toastydeath> rifle stocks and similar things - handles, knobs
[11:30:52] <toastydeath> replacement parts
[11:31:06] <toastydeath> making a knob for a project on a lathe is annoying as fuck

[11:31:12] <toastydeath> if i could just print one? awesome.
[11:31:55] <toastydeath> I actually see the 3d printer as almost a repair tool
[11:32:04] <RyanS> there have been so many "technological revolutions" since the industrial revolution and none of them really come close
[11:32:30] <toastydeath> I think a 3d printer would be fucking awesome if it were able to modify existing parts as well - imagine a 5 axis stage on a 3d printer
[11:32:43] <toastydeath> with not only an injection nozzle, but a hot air welder
[11:33:00] <toastydeath> so that you could extend and add material to things that already exist
[11:33:06] -!- sivoais has quit [Ping timeout: 256 seconds]
[11:33:25] <RyanS> I saw something like a laser deposition machine that did repairs
[11:33:27] <toastydeath> make a part on a mill or lathe, then case it and add an ergonomic handle
[11:33:51] <toastydeath> you could make your own screwdrivers that way
[11:35:19] <RyanS> Facial prosthetics are stil done using old-fashioned moulding and casting
[11:35:56] <RyanS> If you could 3-D scan someone's face and built the part in cad
[11:36:17] <toastydeath> and you can, homebrew laser scanners exist
[11:36:35] <toastydeath> which is actually what my whole idea of a rework/deposition machine would rely on
[11:36:48] <RyanS> And printed in some biocompatible rubber
[11:37:34] <RyanS> However alginate and silicon moulding materials can be accurate enough to recreate fingerprints
[11:37:53] <RyanS> So the 3-D scanning would have to be pretty good quality
[11:38:16] <toastydeath> yeah that's not happening anytime soon, i don't think
[11:38:18] <RyanS> MRI?

[11:40:27] <toastydeath> not saying mri isn't accurate enough to do that type of surgery
[11:40:29] <RyanS> I think im titanium
[11:40:52] <toastydeath> but scanning accurately enough to recreate fingerprints?

I know think I could do it with an MDI command by using G10 L2 P1 X0 Y0. I can add a button to perform this task, but the then I will have two different touch off buttons. Is there a way to just modify the origanl touch off button to d

[18:07:36] <ssi> you can build it on the board, if that's what you're asking
[18:07:51] <jdh> so, slow compiles?
[18:07:57] <ssi> it's not too bad
[18:08:04] <ssi> you could cross compile it, but it's not worth it
[18:08:11] <ssi> kernel, yes... took me 8 hours to build a kernel on board
[18:08:12] <jdh> just a module?
[18:08:16] <ssi> linuxcnc builds in a minute or 2
[18:08:25] <ssi> oh it's not even a module... just a hal component
[18:08:35] <jdh> oh, even easier
[18:08:41] <ssi> yeah it's not that bad

[18:13:16] <ssi> sure
[18:13:18] <ssi> but I don't need that

[18:28:59] <PetefromTn> My kids are out of school and they are sorta camping out in the shop while I work on stuff LOL.
[18:29:12] <Aero-Tec> having trouble running a sub that is a file
[18:29:33] <Aero-Tec> found some mistakes in file sub
[18:29:41] <Aero-Tec> will try to run it now
[18:30:01] <Aero-Tec> is there a way to load a sub file to check it for syntex?
[18:30:03] <Loetmichel> PetefromTn: how much kids?
[18:30:07] <L84Supper> schools seem to be getting out earlier all the time
[18:30:22] <PetefromTn> just two... that's enough LOL.
[18:30:22] <Loetmichel> in my last job i had 4 chlidren runnung around my feet
[18:30:24] <andypugh> Aero-Tec: COmment out the sub/endsub and it should run like an ordinary file.
[18:30:30] <Loetmichel> hence the grey hair now ;-)
[18:30:43] <Aero-Tec> when I tried to load just the sub file it complained about no % or file end, M30

[18:30:58] <Loetmichel> because the workshop was in the cellar of the home of my boss

[18:31:06] <andypugh> (sub)
[18:31:13] <Loetmichel> and he had another company elswehre
[18:31:24] <PetefromTn> that could have been nice I suppose.
[18:31:30] <andypugh> Aero-Tec: So just add an m2 at the end.
[18:31:35] <Aero-Tec> can a sub file have a ending % or M30 and still run with called?
[18:31:43] <pcw_home> subroutines can have elseifs
[18:31:44] <L84Supper> just wait until they reach driving age, you won't see them anymore, just signs of missing food and laundry
[18:31:52] <Loetmichel> so we met ion the morning at his home, he told e waht to mill and buildt and then he goes off to his other comany... and i had the 4 childten and the wife running around my feet ;-)
[18:31:57] <andypugh> Yes. In fact it might require it. After the endsub is where it goes.
[18:32:08] <PetefromTn> I'd love it if I could get this thing moving towards profitability and enjoy their company all the time.
[18:32:22] <andypugh> And, as a plus, they could run the night-shift.
[18:32:35] <PetefromTn> That's a great gig if you can get it. Running someone elses machines and being able to be home with your family at the same time.
[18:32:45] <andypugh> (My dad was using me as a power-feed on his lathe when was 7)
[18:33:05] <PetefromTn> andypugh I'll bet that is a fond memory for you now right...
[18:33:25] <L84Supper> their small hands can get into the detailed parts better

[18:42:27] <PetefromTn> I am working on a drawing for a custom built pig roasting pit fabrication. It is pretty basic but I figure a drawing tells the story better. So far no CNC milling work for the VMC yet except for that job I did yesterday.
[18:43:02] <PetefromTn> jdh LOL I know right. I honestly don't trust them near the machine at all. Hell I don't trust me half the time...
[18:43:38] <PetefromTn> I think if I ever get this thing to a production phase where the machine is running the same program over and over I might try to teach my wife to run it so I can do other things.
[18:43:46] <PetefromTn> Like tig welding and fabrication work.
[18:43:55] <PetefromTn> I mean when she is not at work.
[18:44:59] <PetefromTn> LinuxCNC ran those parts yesterday pretty nicely tho and I just kept hitting go once I got the bugs worked out. Too bad it was not a larger run it was kinda nice to sit and watch the machine actually running properly for a change.
[18:46:38] <jdh> I thought pig roasting was pretty much a known science

[18:53:55] <PetefromTn> He sent me some pictures of one and it looks real stupid simple but we are jazzing this one up just a little bit with a steel dome lid and handles and hinges etc..
[18:54:26] <jdh> vs. split 55gallon drum, steel grate, hinges?
[18:54:27] <PetefromTn> I asked him if I could be invited over when he does the roast and he said sure so I will let ya know how it tastes..
[18:54:55] <PetefromTn> well this thing is 60x36" so a drum won't cut it..
[18:55:10] <PetefromTn> He wants to roast the pig kinda splayed out..
[18:55:47] <PetefromTn> I've already got some rectangular steel here just need some rod and some sheet. but I have not finished the design and given him a price just yet so it may never happen.

[18:59:26] <PetefromTn> rotisserie of pig...nice.
[19:00:18] <andypugh> There was a 1/4 hp motor with its shaft pressed against the bicycle tyre, then the sprocket had a chain wrapped round the second wheel (with no tyre) that was bolted to the end of the scaffolding tube.
[19:00:59] <andypugh> The spoke nipples fitted the chain pitxh exactly, which was something of a bonus.
[19:01:20] <PetefromTn> andypugh Sounds like a linucCNC pig roast. Perhaps you needed a servo motor and mesa card?
