[00:04:23] <fenn> Tom_itx: i get that part, it's just a current sensing resistor
[00:09:45] <fenn> if the daq is outputting 0-5V to the little white box, the 500ohm resistor is only there to prevent accidentalls in case the box is set to measure current instead of voltage
[00:09:54] <fenn> accidents*
[00:10:03] -!- md-2 has quit [Remote host closed the connection]
[00:11:00] <fenn> but in normal use it does nothing, because the box has an input impedance of 50 megaohms
[00:14:09] <fenn> if the daq could output 20mA by itself, the box would be unnecessary too
[00:14:33] <fenn> so if you hook the resistor across the daq output and ground it will draw 10mA which is probably too much current for the daq
[00:17:01] <fenn> actually the resistor wont prevent any accidents it's just cruft

[00:52:43] <zeeshan-lab> figure what out
[00:52:59] <fenn> well you must be working on something, or else go home :P
[00:53:06] <zeeshan-lab> ahha
[00:53:12] <zeeshan-lab> i calibrated all the intput and output
[00:53:17] <zeeshan-lab> so when i write 50C set temp
[00:53:28] <zeeshan-lab> it actually sets it to that on the controller. rather than 51.5 like it was before
[00:53:34] <LatheBuilder2> naja452: did you have to customize the post? The precursor question is did you use it with linuxcnc. I am getting an error on the tool change z height retract. G53 not valid with cutter comp turned on
[00:53:44] <zeeshan-lab> just uploading the datalogs so i can analyze it at home
[00:54:05] <zeeshan-lab> cya!

[01:54:46] <zeeshan> id be happy withj that

[03:33:07] <zeeshan> tom
[03:33:13] <zeeshan> do you use google chrome?
[03:33:16] <Tom_itx> no
[03:33:20] <zeeshan> can you?
[03:33:23] <zeeshan> youre missing out
[03:33:26] <Tom_itx> pfft
[03:33:27] <zeeshan> download it right now please
[03:33:32] <zeeshan> ill show you a cool trick
[03:33:33] <zeeshan> and ull always use
[03:33:34] <Tom_itx> no
[03:33:34] <zeeshan> it
[03:33:44] <zeeshan> because with one click
[03:33:48] <cradek> zeeshan: you're drunk, go home
[03:33:48] <zeeshan> that whole webpage turned into english for me
[03:34:04] <Tom_itx> googlish
[03:34:39] <cradek> do you realize what -hu in the path means?
[03:34:45] <zeeshan> lol
[03:34:47] <ChuangTzu> lol
[03:34:55] <zeeshan> hahahaha
[03:35:13] <zeeshan> thats a good way to fix things
[03:35:17] <Tom_itx> that must be a bad link then.. i started from the english docs
[03:35:30] <zeeshan> http://i.imgur.com/uvrEkbt.jpg
[03:35:31] * Tom_itx looks over at JT-Shop
[03:35:31] <zeeshan> in google chrome
[03:35:32] <cradek> yeah might be a bug? where did you find the link?
[03:35:40] <zeeshan> if you click the top right icon
[03:35:45] <zeeshan> itll translate any pagepretty much
[03:35:48] <zeeshan> from most langauges to english
[03:35:52] <zeeshan> theres no bs involved
[03:35:55] <Tom_itx> http://linuxcnc.org/docs/2.7/html/
[03:35:55] <zeeshan> it takes a sec.
[03:36:01] <zeeshan> this is how i read german pages now
[03:36:08] <ChuangTzu> you can also just put that link into google translate
[03:36:09] <cradek> you don't want to translate the hungarian docs! you want the english docs.
[03:36:10] <ChuangTzu> in any browser you want
[03:36:11] <ChuangTzu> :P
[03:36:23] <zeeshan> ChuangTzu: but thats more work
[03:36:26] <zeeshan> and its not as clean
[03:36:37] <Tom_itx> wait... there's 2 links side by side on the gmoccapy (Magyar) line
[03:36:39] <ChuangTzu> same cleanliness and takes no more work
[03:36:44] <Tom_itx> i clicked the right one...
[03:36:47] <Tom_itx> nevermind
[03:36:47] <ChuangTzu> it's 2 key strokes instead of a mouse click
[03:36:53] <cradek> I wonder what Magyar means
[03:36:57] <zeeshan> how is it two key strokes
[03:36:58] <Tom_itx> that still should be fixed
[03:37:03] <zeeshan> you gotta go to google translate first
[03:37:03] <ChuangTzu> zeeshan: vimperator
[03:37:07] <zeeshan> then press more
[03:37:10] <ChuangTzu> i can make it one key stroke
[03:37:11] <Tom_itx> zeeshan, there are 2 links on the same line
[03:37:25] <zeeshan> like i said
[03:37:27] <zeeshan> thsi is standard stuff
[03:37:29] <cradek> > The Hungarian people refer to themselves by the demonym "Magyar" rather than the term "Hungarian".
[03:37:31] <zeeshan> in a real web browser
[03:37:32] <ChuangTzu> currently it's one key stroke to copy the current url, and one key stroke to open it in google translate
[03:37:33] <zeeshan> not some addon
[03:37:46] <ChuangTzu> vimperator is house i interact with the web
[03:37:54] <ChuangTzu> whether you consider it real or not
[03:37:59] <cradek> so you clicked on something like (Hungarian) but didn't know it
[03:38:03] <zeeshan> suit yourself
[03:38:06] <Tom_itx> yes
[03:38:22] <Tom_itx> http://linuxcnc.org/docs/2.7/html/
[03:38:30] <cradek> we have several translations and I don't know why just that one is right there
[03:38:36] <Tom_itx> the gmoccapy (Magyar) line has 2 links there
[03:38:50] <Tom_itx> it should be moved
[03:38:52] <cradek> maybe JT-Shop is working on it. I know this is in flux
[03:38:56] <Tom_itx> i know
[03:39:04] <Tom_itx> he may not be aware of that one
[03:39:08] <cradek> yeah
[03:39:17] <cradek> please make sure he knows (tomorrow?)
[03:39:22] <Tom_itx> yeah
[03:39:53] <cradek> if we want translation links there, I'd expect more like (fr) (pt) (hu) or whatever we have
[03:40:01] <Tom_itx> yeah
[03:40:11] <Tom_itx> it was unexpected here for sure
[03:40:15] <cradek> yep
[03:41:07] <Tom_itx> also his expand/collapse button stops at +Developer Information
[03:41:13] <Tom_itx> below that doesn't expand
[03:41:24] <Tom_itx> dunno if that was intentional or not
[03:41:53] <Tom_itx> i'll ask tomorrow
[03:42:16] <cradek> thanks for testing
[03:42:50] <Tom_itx> i think i finally got my control back in one working piece now hopefully
[03:46:15] <Tom_itx> click on the Espańol link at the top and alot of that is in english and the gmoccapy line there is a single link
[03:46:46] <Tom_itx> i'm guessing that translation is still a work in progress
[03:47:00] * zeeshan cant wait for the 2.7 release
[03:47:03] <zeeshan> stable :d
[03:47:09] <zeeshan> cradek in your opinion
[03:47:10] <Tom_itx> use it now
[03:47:13] <Tom_itx> i am
[03:47:14] <zeeshan> is the base system stable?
[03:47:25] <zeeshan> really wanna use moveoff
[03:47:31] <zeeshan> and the new tp
[03:47:34] <Tom_itx> so what you waitin for?
[03:47:44] <zeeshan> Tom_itx: do you make parts though!?!?! :P
[03:47:50] <Tom_itx> of course
[03:47:55] <Tom_itx> not lately but i do
[03:48:10] <zeeshan> it the tp noticeably different?
[03:48:19] <Tom_itx> JT-Shop says it is
[03:48:26] <Tom_itx> he used it on his plasma table
[03:48:40] <fenn> cradek: also the expansion stuff screws up on non-javascript browsers like dillo, it doesn't display at all. would be better if everything were expanded
[03:48:48] <zeeshan> those are higher feedrates though where i think the new tp is supposed to shine
[03:49:24] <Tom_itx> fenn, the expand/collapse was per my request... originally he had it all collapsed
[03:49:37] <Tom_itx> tradeoffs...
[03:50:33] <Tom_itx> fenn, would it work if it defaulted to expanded?
[03:50:39] <Tom_itx> with the option
[03:50:43] <zeeshan> Tom_itx: do you think id notice a different in chip break cycles?
[03:50:43] <fenn> i don't know
[03:51:25] <Tom_itx> zeeshan i haven't run it enough to tell but i wouldn't be surprised
[03:52:20] <fenn> it would be better if the js actively set the div's to "display: none" instead of them starting out that way, and then you have no way to change it
[03:52:24] <Tom_itx> canned cycles? it may not affect them...

[03:54:27] <zeeshan> The current tp peaks somewhere around 100ipm(first run) - the new tp peaks over 400ipm(second run)
[03:54:28] <zeeshan> hmm
[03:54:32] <zeeshan> maybe i would notice a difference

[05:28:13] <fenn> trentster: just bump the linear bearing blocks up to about level with the y-axis ballscrew and cut off the excess plate. also move your spindle mount down
[05:28:57] <fenn> i wouldn't worry about the slide sticking up too far unless you have limited ceiling space or something
[05:30:37] <trentster> fenn: thanks - I was thinking of doing the same thing. I have a shorter ballscrew arriving today as well as it probably makes no sense to have such a long 400mm ballscrew in there. The new one is 250mm
[05:31:14] <fenn> what is the new height from table to bottom of y axis support beams?
[05:31:35] <trentster> I then need to decide if I should just cut the supported round bar rail or I should use micro 14mm linear slides which I have - but that would involve a complete redesign
[05:32:11] -!- postaL has quit [Quit: ZNC - http://znc.in]
[05:32:13] <trentster> fenn: new height is about 80mm between table top and bottom gantry beam
[05:32:27] <fenn> ok so you only need 80mm of travel
[05:33:19] <fenn> it seems a shame to cut up a perfectly good z axis
[05:33:34] <trentster> yup - but the machine spindle also makes it over the edge of the machine so in theory I could work on very tall material like solid wood beams etc - tho I doubt that will happen often if ever
[05:34:33] <fenn> you never know when you'll have to threadmill the end of a .50 BMG
[05:34:43] <trentster> ha ha - yeah
[05:35:42] <trentster> Since I would be classified as a terrorist for owning something like that in Australia - I don't think its gonna happen. Would be fun tho

[13:10:39] <cradek> wow 2.7 gives 30.0000 and 40.0000 now!? that's really terrific.

[13:11:47] <cradek> oh, I was looking at
http://i.imgur.com/OwyvuM1.png
[13:12:35] <cradek> figured we had fixed the last bug this time (haha)
[13:12:38] <skunkworks> I had to scale the gcod differently to run in 2.6... So instead of 5X it is 2X and the 1% overage in 2.7 disapeared
[13:12:44] <skunkworks> gcode
[13:12:51] <cradek> interesting
[13:13:21] <cradek> I bet very occasional 1% doesn't matter at all
[13:13:26] <skunkworks> right

[13:36:29] <lair82> Hello Guys, I ma working on another mill that I currently have no way of connecting to the internet, doe the info in the
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Installing_LinuxCNC#Accomplishing_the_above_steps_on_an_offline_machine work on a Debian Wheezy build?
[13:36:53] <lair82> < I am > not I ma
[13:38:05] <cradek> I don't know :-/
[13:38:10] -!- skunkworks has quit [Ping timeout: 240 seconds]
[13:38:30] <lair82> I guess I will give it a shot,
[13:38:31] <cradek> please update the instructions as you work it out
[13:38:58] <cradek> I guess you could install the cd and never update it, but you miss out on bugfixes
[13:41:33] <CaptHindsight> is upgrading packages from a folder on the HD, flash drive or CD somehow disabled in the Wheezy build?
[13:43:29] <cradek> of course not
[13:44:03] <cradek> it's apt. it does all the apt things.
[13:45:32] <lair82> I just wondered, I did not know if it would act differently on Debian, and in the wiki the first line says "While now somewhat out-of-date and not complete with respect to transferring the LinuxCNC source files, they contain the essential ingredient,"

[13:49:48] <cradek> it seems like those might be useful to you, but I've never used them
[13:51:11] <cradek> are you trying to update linuxcnc, or install build dependencies and build? it looks like tom was doing the latter

[15:21:51] <zeeshan> hi
[15:22:53] <ssi> zee
[15:22:58] <zeeshan> yo
[15:23:06] <zeeshan> did you see the pics of the machine?
[15:23:11] <ssi> no
[15:23:19] <zeeshan> youll see why i dont want it :/
[15:23:23] <zeeshan> even though it is bad ass
[15:23:39] <zeeshan> http://imgur.com/a/fQEVW
[15:24:53] <ssi> yeah that'll be a lot of work
[15:25:06] <zeeshan> the turrett and y axis
[15:25:07] <zeeshan> are all apart
[15:25:26] <zeeshan> http://i.imgur.com/xac3a7J.jpg
[15:25:28] <zeeshan> what is this?
[15:25:29] <zeeshan> couldnt figure it out
[15:25:40] <zeeshan> door closer?
[15:25:43] <ssi> chip conveyor maybe?
[15:25:47] <zeeshan> nahh
[15:25:48] <zeeshan> thats on the other side
[15:25:54] <zeeshan> wait
[15:25:56] <zeeshan> maybe youre right
[15:25:58] <zeeshan> but its attached to the door
[15:26:25] <ssi> dunno
[15:26:30] <zeeshan> dude
[15:26:32] <zeeshan> but the problem is
[15:26:35] <zeeshan> its apart, he says its htere

[15:26:45] <zeeshan> but i told him it might just be worth scrapping it
[15:26:48] <zeeshan> cause no ones gonna buy it like this
[15:26:52] <zeeshan> unless they're very special
[15:27:00] <zeeshan> and know the machine inside out and can tell if the parts are there or not
[15:27:04] <tiwake> is that a subspindle I spy?
[15:27:05] <zeeshan> irregardless of him wanting 3800
[15:27:07] <zeeshan> yea
[15:27:10] <zeeshan> sub spindle
[15:27:11] <zeeshan> c axis
[15:27:13] <zeeshan> y axis
[15:27:16] <zeeshan> its a full mill turn center
[15:27:21] <tiwake> ooo
[15:27:23] <zeeshan> live tooling
[15:27:29] <tiwake> but completely taken apart
[15:27:32] <tiwake> bah
[15:27:34] <pcw_home> if the controller and drives are good those are worth something
[15:27:35] <pcw_home>
[15:27:56] <zeeshan> pcw_home: no way to verify
[15:28:00] <tiwake> that would be a nightmare putting it together
[15:28:06] <pcw_home> but not 3800
[15:28:20] <zeeshan> pcw_home: he showed me papers at same auction same machine went for 90000
[15:28:22] <zeeshan> in working condition
[15:28:35] <tiwake> well sure
[15:28:38] <zeeshan> that is what got to me
[15:28:39] <pcw_home> well thats a fair way from working condition
[15:30:00] <zeeshan> tell me what to do!!
[15:30:12] <tiwake> offer him $1500
[15:30:16] <zeeshan> he wont take it
[15:30:22] <tiwake> then he can keep it
[15:30:22] <zeeshan> hehe
[15:30:43] <zeeshan> i think your offer is fair
[15:30:46] <zeeshan> in the current condition it is
[15:30:56] <zeeshan> because itll cost 1500 bux just to move this heap of shit
[15:31:10] <pcw_home> missing/broken parts would make It a much more expensive to restore
[15:31:11] <zeeshan> and probably another 2000-3000 assuming all parts are there
[15:31:16] <zeeshan> to fix it
[15:31:22] <zeeshan> as far as i could see
[15:31:28] <zeeshan> all the turrett and y axis stuff weas there
[15:31:34] <tiwake> $4000+ (after shipping), more likely $6,000 after shipping, its not worth it
[15:31:36] <zeeshan> the only thing that can be missing is the live tooling
[15:32:34] -!- PetefromTn_ [PetefromTn_!~IceChat9@75-136-59-160.dhcp.jcsn.tn.charter.com] has joined #linuxcnc
[15:33:00] <tiwake> for that much you can get other useful working-condition machines
[15:33:06] <zeeshan> yep
[15:33:08] <zeeshan> but not with a sub spindle
[15:33:08] <pcw_home> wonder why they disassembled it?
[15:33:10] <zeeshan> and live tooling
[15:33:14] <zeeshan> pcw_home: me too
[15:33:19] <zeeshan> something definitely was mechanically wrong
[15:33:50] <zeeshan> can you run those fanuc drives
[15:33:52] <zeeshan> off single p[hase
[15:33:58] <zeeshan> just by giving them single phase instead of 3 phase
[15:34:00] <zeeshan> and derating them
[15:34:17] <zeeshan> like with a normal vfd you can do tha tr
[15:34:21] <zeeshan> but im not sure about these drives..
[15:34:29] <tiwake> 1-phase -> 3phase thing, sure
[15:34:39] <zeeshan> like do they convert the 3 phase
[15:34:43] <zeeshan> into dc
[15:34:44] <zeeshan> and then invert
[15:35:18] <pcw_home> Possibly but I'm pretty sure they have phase voltage checking
[15:35:39] <pcw_home> Yes those drives are actually very simple
[15:36:05] <tiwake> zeeshan: just leave it be, you will be happier in the long run
[15:36:13] <tiwake> unless he will take less for it
[15:36:16] <Rab> zeeshan, a friend of mine was bitten that way by Yaskawa drives. They do convert 3-phase to DC, but do the rectification with triacs driven by a uC watching the zero crossings.
[15:36:39] <zeeshan> worse comes to worse
[15:36:41] <Rab> He had a plan to fake out the phase detection, but ended up finding a rotary converter.
[15:36:43] <zeeshan> i'd be selling these drives
[15:36:47] <zeeshan> im sure they are worth a lot of $
[15:36:48] <pcw_home> the drives themselves are dumb (just a 3 phase HBridge with current sensing no smarts at all)
[15:37:08] <pcw_home> the controller has all the smarts
[15:37:27] <Jymmm> pcw_home: Sounds like me before first cup of coffee
[15:37:45] <pcw_home> :-)
[15:39:09] <zeeshan> realisticallyu
[15:39:13] <zeeshan> his price isn't that unfair
[15:39:26] <zeeshan> its 11,400 lb depending onwhat spec sheet you read
[15:39:27] <tiwake> zeeshan: stop.
[15:39:34] <zeeshan> $300 / 1000lb up here
[15:39:35] <tiwake> zeeshan: walk away.
[15:39:40] <zeeshan> thats 3600$ in scrap metal lol
[15:39:56] <pcw_home> Might be a bargain if you had a machine you wanted spares for
[15:40:00] <Jymmm> My left-rear brake sorta locked up yesterday and started smoking after a 4 mile drive with it like that. parking brake was off, but I did feel a drag (thought it was just the hills in the area), has anyone ever heard of ONE brake (not all four) doing this?
[15:40:33] <PetefromTn_> sure can
[15:40:53] <PetefromTn_> I have had that happen before to my old truck
[15:40:57] <zeeshan> Jymmm: time for a new car :P
[15:41:05] <zeeshan> but yea that happens all the time!
[15:41:16] <Jymmm> PetefromTn_: what was it? parking brake?
[15:41:27] <PetefromTn_> seized piston
[15:41:40] <Jymmm> PetefromTn_: did you have to replace it or???
[15:42:03] <PetefromTn_> well as I recall we just swapped out a whole new caliper it was pretty cheap
[15:42:28] <Jymmm> what year? Mine is a 2001 Ford Expedition
[15:42:29] <PetefromTn_> but you can remove and thoroughly clean them if it is not too damaged
[15:42:39] <PetefromTn_> that was my old Dodge Ram I think
[15:42:44] <Jymmm> year?
[15:42:51] <PetefromTn_> 1998?
[15:43:45] <Jymmm> hmmm, ok. Today I get to pull EVERYTHNG out of the garage, remove 1600 lbs off the racks because I can't get the casters repaired and can't get to any tools to fix the car
[15:43:47] <PetefromTn_> sucked cause it left me stranded had to get towed
[15:44:32] <Jymmm> That does suck, I always feel bad when I see someone stranded on the side of the road... poor bastards.
[15:44:38] <PetefromTn_> just got back from Knoxvegas with a full argon cylinder.... damn that thing is heavy sheesh
[15:44:54] <Jymmm> 125CF ?
[15:45:17] <PetefromTn_> I had AAA but they were like it is a fullsize extra cab 4x4? Jeez gonna need a bigger tow truck LOL
[15:45:26] <PetefromTn_> no this is a 336 CF
[15:45:47] <Jymmm> PetefromTn_: Yeah, a 10 ton truck
[15:45:59] <Jymmm> eeeesh, big tank
[15:46:02] <PetefromTn_> I remove the back seat in my Astro Van and kinda rollit in there and it is still a bitch
[15:46:15] <PetefromTn_> yeah they sent a huge rollback
[15:46:22] <Jymmm> you need a overhead crane in your van =)
[15:46:56] <PetefromTn_> that's not a bad idea actually
[15:46:59] <Jymmm> Comments?

[15:47:56] <Jymmm> bbiab
[15:48:22] <PetefromTn_> it's funny my Tig welder is a huge bastard and it has this shelf on the back you rest the bottle on and it sits like three inches above the floor.... trying to get the tank onto that ledge is the hardest part I think LOL
[15:49:09] <zeeshan> haha
[15:49:26] <zeeshan> it doesnt lower down?
[15:49:51] <zeeshan> what size tank
[15:50:30] <PetefromTn_> not that I am aware of.. it is like a shelf with gates on three sides and you gotta put the tank bottom on the edge and angle it up...which is about when the whole tig welder starts to roll... I usually jam some hose or chord under the front wheels but I forgot this time LOL.
[15:50:37] <PetefromTn_> 336CF

[15:59:52] <PetefromTn_> my local supplier only rents the big ones so that is what I get. I pay $220 for 5 year rental and then a fill is like $90.00 now apparenlty...Shits not cheap
[16:00:28] <zeeshan> its 60 bux a year for rental here
[16:00:31] <zeeshan> for 5 year contract
[16:00:35] <zeeshan> so you guys get it cheap!
[16:00:44] <zeeshan> (300)
[16:00:50] <zeeshan> fill up is like $110
[16:01:00] <zeeshan> everytime i go its a different price lol
[16:01:01] <PetefromTn_> woah I guess I shouldn't complain
[16:01:17] <zeeshan> you know whats funny?
[16:01:20] <PetefromTn_> yeah I know right me too.... I could have sworn it was only $78.00 last time
[16:01:22] <zeeshan> they're actually got the plant in the back
[16:01:24] <zeeshan> to produce argon
[16:01:32] <zeeshan> like this is the source!
[16:01:36] <PetefromTn_> same as this place it is HUGE
[16:01:37] <zeeshan> which ships to a lot of locations in ontario
[16:01:51] <PetefromTn_> if you order enough they will deliver it for you
[16:02:08] <zeeshan> i replace a tank maybe once every 2 months
[16:02:13] <zeeshan> depending on the amount of work
[16:02:16] <zeeshan> so that isnt enough :(
[16:02:24] <PetefromTn_> but I am just plain old me here doing CNC machining and tig welding and it takes me awhile to drain the big tank
[16:02:27] <zeeshan> at our school they deliver every week
[16:02:34] <PetefromTn_> WOW you must do a ton of welding then
[16:02:55] <PetefromTn_> admittedly I don't do a ton of fab work tho
[16:02:57] <zeeshan> about 15ish hours in 2 months is about normal
[16:03:02] <zeeshan> weld time
[16:03:19] <zeeshan> PetefromTn_: try advertising it on local places
[16:03:24] <zeeshan> i score a lot of aluminum work
[16:03:28] <zeeshan> try this yourself
[16:03:32] <PetefromTn_> I am TRYING to get some work from the local places and it is picking up now
[16:03:36] <zeeshan> casll around to get quotes for getting some aluminum welded
[16:03:40] <zeeshan> you'll see they'll shrug you off
[16:03:43] <zeeshan> or as a ton aof $$
[16:03:53] <zeeshan> even if you're at 60-75% of what they want
[16:03:56] <zeeshan> you're making serious $
[16:04:00] <zeeshan> for not a lot of work
[16:04:05] <PetefromTn_> I got some stainless tig work coming in Monday and I am working on some right now...
[16:04:35] <zeeshan> like tell me how much you think is a fair amount to charge to weld 4 on 0.0625" aluminum 3" diameterr tubing
[16:04:39] <PetefromTn_> honestly there are quite a few fab shops around here that will do Tig work for you...most of the machine shops do it as well...
[16:04:57] <zeeshan> most places here won't even want to do that.
[16:05:15] <zeeshan> now the places that will do that
[16:05:27] <PetefromTn_> probably 2 hours or so I guess?
[16:05:52] <zeeshan> they'd charge for 2-3 hours depending on the shop
[16:06:00] <zeeshan> but in reality it only takes 45 min to an hour
[16:06:13] <PetefromTn_> sounds about right when you consider setting up and whatnot
[16:06:27] <zeeshan> so basically 150-225
[16:06:36] <PetefromTn_> I am not the worlds greatest aluminum Tig welder tho...
[16:06:38] <zeeshan> i usually charge 120 for that
[16:06:47] <zeeshan> and i usually get the job
[16:06:52] <PetefromTn_> I don't charge that much
[16:07:15] <PetefromTn_> 2 hours would be about $75
[16:07:57] <zeeshan> i work out the cost like this:
[16:08:02] <PetefromTn_> speaking of Tig welding what sort of cup and tungsten/gas setup are you using on those stainless turbo exhausts?
[16:08:24] <zeeshan> 335 cf tank you get about 16 hours of welding, each tank cost me $130 to bring to my place (taxes + gas money)
[16:08:40] <zeeshan> so i need at least 8.13$ per hour just for covering gas
[16:08:49] <PetefromTn_> sure
[16:08:53] <zeeshan> filler and tungsten anoither $6 bux
[16:08:56] <PetefromTn_> then consumables
[16:09:05] <zeeshan> electricity around $3
[16:09:17] <zeeshan> so at minimum per hour i need 17.13 without my cost
[16:09:56] <PetefromTn_> cracks me up how people think Tig weding should be cheap LOL
[16:10:16] <PetefromTn_> damn guy charges me $40.00 just to mow my damn lawn and it only takes him a half hour
[16:11:18] <zeeshan> sorry bustuing out the excel file from the last job
[16:11:40] <zeeshan> i calculated 20 min per weld
[16:11:59] <zeeshan> 80 minutes * 1.20 (20% buffer for time)
[16:12:10] <zeeshan> 1.6 hours
[16:12:30] <zeeshan> 27.40 for gas + material cost + electricity
[16:12:47] <zeeshan> so i made 92.60$ for that job when i charged 120
[16:13:02] <zeeshan> that is fair no?
[16:13:15] <zeeshan> if they want blobby welds for $100 bux an hour at a regular shop
[16:13:17] <zeeshan> be my guest!
[16:13:38] <zeeshan> for .065 304 stainless tubing
[16:13:43] <zeeshan> i use a gas lense
[16:13:52] <zeeshan> if i can fit it
[16:13:53] -!- quiqua has quit [Quit: quiqua]
[16:14:04] <zeeshan> then i use 1/16 tungsten
[16:14:14] <zeeshan> and 0.032 thou stainless filler
[16:14:21] <zeeshan> (if it really needs filler)
[16:14:28] <zeeshan> most of the time you can get away with fusion welding
[16:14:51] <zeeshan> sorry for the tangent :P
[16:14:56] <zeeshan> i like calculations :)
[16:15:47] <PetefromTn_> no that is fine...
[16:16:36] <PetefromTn_> I use 3/32 tungstens but this guy wants me to start doing a bunch of his Tig welding on stainless headers/turbo stuff and to be honest it is pretty new to me. I have welded all sorts of stuff but never this exhaust tubing
[16:17:09] <PetefromTn_> it HAS to look glorious or they are not happy so I am trying to get my game face on here and order the best possible stuff/gas lenses etc etc...
[16:17:13] <zeeshan> the big tungsten is very hard to control the puddle
[16:17:19] <PetefromTn_> I was looking at some of those pyrex cups
[16:17:20] <zeeshan> cause the heat isn't as focused
[16:17:30] <PetefromTn_> thats a good point...
[16:17:34] <zeeshan> do you have some test pieces you can but weld on?
[16:17:47] <PetefromTn_> I have a WP17F torch here
[16:17:50] <zeeshan> same here
[16:17:58] <zeeshan> i dont know f
[16:18:00] <zeeshan> but mine is size 17
[16:18:05] <PetefromTn_> Oh yeah I have a bunch of pieces I have been practicing on..
[16:18:12] <zeeshan> i dont know if youve done this already
[16:18:14] <PetefromTn_> F is Flex head
[16:18:20] <zeeshan> but use just a regular cup
[16:18:22] <zeeshan> say a #6
[16:18:34] <zeeshan> stick the tungsten out like 0.030
[16:18:41] <zeeshan> so its pretty much hiding inside the cup
[16:18:50] <zeeshan> make sure its a super sharp point
[16:19:01] <zeeshan> take two pieces that absolutely have no gap in them
[16:19:05] <zeeshan> i literally mean no gap
[16:19:09] <zeeshan> (barely any light goes through)
[16:19:16] <zeeshan> set your welder to dc and 45A
[16:19:27] <zeeshan> hold it perpendicular to the butt joint
[16:19:37] <zeeshan> and try to weld it without filler
[16:19:46] <PetefromTn_> fusion weld....yeah I do that all the time
[16:19:48] <zeeshan> try to carry the puddle all the way to the back
[16:19:54] <zeeshan> if it's not coming out colorful
[16:19:58] <zeeshan> youre going too fast
[16:20:05] <zeeshan> (if its grey)
[16:20:13] <zeeshan> or you're going too slow
[16:20:13] <zeeshan> haha
[16:20:17] <zeeshan> that's the dilemma :P
[16:20:24] <zeeshan> both will give the same effect
[16:20:30] <PetefromTn_> they actually fired the guy they had doing all of their fab and Tig work the other day LOL
[16:20:51] <PetefromTn_> so now they are wanting me to do at least some of it for them
[16:20:51] <zeeshan> hehe
[16:20:57] <zeeshan> do it man
[16:20:59] <zeeshan> its good money
[16:21:04] <PetefromTn_> yeah it is actually...
[16:21:17] <zeeshan> my problem with welding is
[16:21:19] <PetefromTn_> I prefer CNC machining but I need the money so I do whatever LOL
[16:21:21] <zeeshan> I GOTTA SIT THERE AND DO IT
[16:21:23] <zeeshan> it bothers me a lot
[16:21:30] <zeeshan> with machining you can set up the program and walk away
[16:21:41] <zeeshan> it really takes a toll on me if im welding for 5 hours straight
[16:21:45] <PetefromTn_> I could if my DAMN TOOLCHANGER was working LOL
[16:22:25] <PetefromTn_> honestly most of the programs I do are not long and require multiple setups so it is not that big a deal so far anyway
[16:22:41] <PetefromTn_> if I had constant work in here and was scrambling to keep up I would HAVE to get it going correctly.

[16:32:13] <zeeshan> i feel like we're hitting another recession
[16:32:17] <zeeshan> machine selling ads are going up
[16:32:22] <zeeshan> lots more auctions
[16:32:26] <zeeshan> jobs are slower
[16:33:21] <zeeshan> im worried about this wood job
[16:33:24] <zeeshan> ive never machined wood in my life
[16:33:32] <zeeshan> i use it to make shelves
[16:33:35] <zeeshan> not parts! :P
[16:33:46] <jdh> wood is messy
[16:36:03] <PetefromTn_> zeeshan So you think the 1/16 tungsten makes a big difference in controllability then?
[16:37:59] <PetefromTn_> http://www.ebay.com/itm/TIG-Welding-Weld-12-Pyrex-Flare-Cup-Kit-Torches-9-20-Gas-Lens-3-32-/171749170328?hash=item27fd0c5c98 I was looking at getting something like this...
[16:40:03] <zeeshan> definitely
[16:40:11] <zeeshan> you go from blowing a hole
[16:40:23] <zeeshan> to be able to hold it the puddle infinitely there
[16:40:33] <zeeshan> i dont think you need that to be honest
[16:40:46] <zeeshan> its nice
[16:40:53] <zeeshan> but i think a regular cheapo gas lense does the job
[16:42:34] <PetefromTn_> they don't seem to sell those with 1/16 tungsten setups
[16:42:51] <PetefromTn_> I think the clear cup would really help visibility in tight spots
[16:42:59] <zeeshan> they do!
[16:43:04] <zeeshan> i have it

[16:43:43] <PetefromTn_> I've got several of those here...
[16:43:51] <PetefromTn_> I call them the CAVE MAN setup lol
[16:43:54] <zeeshan> that is all you need!! :P
[16:44:13] <zeeshan> you know me im opinionated
[16:44:21] <zeeshan> but i dont know what the big deal with the clear glass is
[16:44:23] <zeeshan> ive tried it
[16:44:25] <zeeshan> i dont notice a differnce
[16:44:33] <PetefromTn_> every video I watch of really highly skilled guys they seem to use these short gas lense setups and pyrex cups
[16:44:55] <PetefromTn_> Oh you're OPINIONated that's for sure LOL
[16:45:02] <zeeshan> i learned my welding from
[16:45:04] <zeeshan> magnusmotorsports.com
[16:45:35] <PetefromTn_> ?
[16:45:38] <zeeshan> http://magnusmotorsports.com/wp-content/uploads/2015/05/TB-Adapter-1-1024x680.jpg
[16:45:46] <zeeshan> he doesnt use that pyrex stuff
[16:45:50] <zeeshan> just straight up regular glas lens
[16:47:02] <PetefromTn_> I think I actually have some 1/16 tungstens here I gotta check... and a gas lens for them but not that shortie pyrex stuff
[16:47:16] <PetefromTn_> I also use an abbreviated tungsten and a short stop cap
[16:47:50] <PetefromTn_> Have you ever seen that guy ToxicFab? He is a magician I swear..
[16:48:09] <zeeshan> nope
[16:48:23] <zeeshan> theres 2 guys in the forums that are "gods" of tig welding
[16:48:29] <zeeshan> in the forums i follow that is
[16:48:58] <zeeshan> marcella
[16:49:00] <zeeshan> who does work like this:
[16:49:31] <zeeshan> http://i448.photobucket.com/albums/qq201/Marcella_manifolds/IMG_0318.jpg
[16:49:36] <zeeshan> he's absolutely frigging CRAZY
[16:49:37] <zeeshan> LOL
[16:49:40] <zeeshan> i can never do that
[16:50:11] <zeeshan> http://marcellamanifolds.net/images/IMG_0336rev0rev0.jpg
[16:50:16] <zeeshan> that is his normal stuff
[16:50:18] <PetefromTn_> https://www.facebook.com/ToxicFab?fref=ts
[16:50:56] <zeeshan> wow thats skill
[16:51:02] <zeeshan> i can never get my filler that consistent
[16:51:03] <zeeshan> im okay
[16:51:05] <zeeshan> but not that
[16:51:15] <PetefromTn_> yeah man he is probably one of the best I have ever seen..
[16:51:18] <PetefromTn_> Me neither LOL
[16:51:29] <PetefromTn_> I have only been tig welding for about two years or so...
[16:51:38] <PetefromTn_> taught myself from youtube videos
[16:52:11] <zeeshan> dont be embarassed to post shit weld pics
[16:52:13] <zeeshan> i can try to help
[16:52:24] <zeeshan> if i can find my very first aluminum weld
[16:52:27] <zeeshan> you're gonna love it :-)
[16:52:28] <PetefromTn_> that guy sells ceramic number 14 cups with 1/16 tungstens but he is always out of stock
[16:52:49] <PetefromTn_> I don't really have any weld pics actually
[16:53:00] <PetefromTn_> usually the welding jobs I get are in a hurry
[16:53:07] <PetefromTn_> so I never have time to take any LOL
[16:53:21] <PetefromTn_> as I get into this Stainless tube I will try to post some tho..
[16:54:09] <PetefromTn_> I would like to try the thinner tungsten because that problem of wandering gap is a big one for me... even when I am really steady the arc moves all around on me.
[16:54:32] <zeeshan> do your tungsten look like a pencil?
[16:54:38] <zeeshan> and are you grinding in the same direction
[16:54:44] <archivist> I paint my welds after dressing, only then take pictures :)
[16:54:47] <zeeshan> so all the lines are facing towards the point?
[16:54:50] <PetefromTn_> I usually put them in a cordless drill and take them to my belt sander
[16:55:06] <zeeshan> that isn't correct if im understanding it right
[16:55:08] <PetefromTn_> making the tip parallel with the travel of the belt
[16:55:13] <zeeshan> okay
[16:55:18] <zeeshan> so you get line grind marks
[16:55:24] <zeeshan> rather than circles around the tungsten
[16:55:29] <PetefromTn_> marks are along the axis of the tungsten
[16:55:32] <PetefromTn_> yes
[16:55:37] <zeeshan> so its not that
[16:55:43] <PetefromTn_> and I usually just touch the tip when I am done
[16:55:53] <zeeshan> that you wanna do for aluminum
[16:55:56] <zeeshan> to help balling
[16:56:03] <zeeshan> (for our beastly transformer type welders)

[16:56:26] <PetefromTn_> but it does not have pulsing
[16:56:39] <zeeshan> you can pulse by foot :P
[16:56:43] <PetefromTn_> yeah I know
[16:56:54] <PetefromTn_> I also have a little problem with my foot pedal right now...
[16:57:09] <PetefromTn_> it does not shutoff completely when I let go so I have to pull away
[16:57:19] <PetefromTn_> drives me frackin' nutz
[16:58:08] <PetefromTn_> How far would you say you normally travel on the side of a header tube?
[16:58:59] <zeeshan> like in between dabs of filler?
[16:59:08] <PetefromTn_> no between stops
[16:59:15] <zeeshan> oh
[16:59:25] <zeeshan> if its a 2" tube i break it into 6 segments
[16:59:31] <zeeshan> along the periphery
[16:59:37] <PetefromTn_> Ok
[16:59:50] <PetefromTn_> I have seen pro's go shorter and farther..
[17:00:13] <zeeshan> only these top notch guys
[17:00:14] <PetefromTn_> a lot of them just go maybe an inch or so around and stop/reposition
[17:00:20] <zeeshan> can hide their stop and start marks
[17:00:22] <zeeshan> i cant do it
[17:00:24] <zeeshan> i dont even bother anymore
[17:00:25] <zeeshan> lol
[17:00:31] <PetefromTn_> it's nearly impossible I think

[17:00:48] <zeeshan> you gotta be perfect
[17:00:57] <PetefromTn_> fer sure
[17:01:11] <PetefromTn_> it's the stops and starts that are my biggest problem
[17:01:40] <PetefromTn_> I can lay a decent bead in between but picking up and stopping without little problems is where I fall down.

[17:34:08] <zeeshan> they warp.
[17:34:15] <zeeshan> i always have to machine them flat after
[17:36:16] <PetefromTn_> yeah that is typical I think... what thickness are your flanges?
[17:36:21] <zeeshan> 1/2"!!!
[17:36:30] <PetefromTn_> thats what theirs are too..
[17:36:36] <PetefromTn_> turbo flange is thick as well
[17:36:38] <zeeshan> somehow magically
[17:36:43] <zeeshan> these people get away with 1/2" with no warp
[17:36:46] <zeeshan> 3/8 will warp
[17:36:51] <zeeshan> but i dont know how they do it with 1/2"
[17:36:52] <PetefromTn_> doubt it
[17:36:59] <zeeshan> they're just talking shit
[17:37:02] <zeeshan> they dont even check for flatness

[17:37:31] <zeeshan> most of these guys dont even know what a granite plate is
[17:37:39] <PetefromTn_> flat is relative
[17:37:48] <zeeshan> flat has one meaning to a machinist!
[17:37:55] <zeeshan> you put it on a flat surface like a plate
[17:38:04] <zeeshan> and try to put feeler gauges under it
[17:38:05] <PetefromTn_> these guys are NOT machinists LOL
[17:38:07] <zeeshan> or sweep the surface
[17:38:16] <ssi> or spot blue it

[17:39:17] <zeeshan> cause it is time consuming work
[17:39:24] <PetefromTn_> flat is what happens to my tires on some of these tennesse roads LOL
[17:39:27] <zeeshan> in the past i used to source it out
[17:39:30] <zeeshan> but now i do i t myself
[17:39:38] <ssi> flat is how a cherokee six lands with no weight in the back seats :D
[17:39:45] <zeeshan> stainless flanges are a bitch too
[17:39:55] <PetefromTn_> rather OHIO roads
[17:39:56] <zeeshan> if you try to use a belt sander to flatten them
[17:40:00] <zeeshan> you're chasing your own tail
[17:40:05] <zeeshan> asap they're off and cooling
[17:40:06] <zeeshan> they warp again
[17:40:07] <furrywolf> flat is how some of these puns are starting to land. :P
[17:40:07] <zeeshan> ahha
[17:40:15] <zeeshan> steel doesn't do it as bad :)
[17:40:32] <PetefromTn_> these guys actually use mild steel flanges to stainless tube
[17:40:37] <zeeshan> perfect
[17:40:48] <zeeshan> 309l on the interrface of mild steel to stainless
[17:40:51] <zeeshan> and it works great
[17:40:54] <Rab> zeeshan, can you weld the flanges while they're bolted to a more rigid jig?
[17:40:58] <PetefromTn_> I am going to me machining some of the harder to get flanges for them here apparently
[17:40:59] * furrywolf doesn't know much about tn geography, but always had the feeling it's not nearly as rugged as ca.
[17:41:05] <zeeshan> Rab: you'd think that'd work
[17:41:18] <PetefromTn_> actually that is how you do it...
[17:41:31] <zeeshan> think of a quick jig
[17:41:32] <zeeshan> that you could use
[17:41:48] <zeeshan> http://i.imgur.com/EjKMccG.jpg
[17:41:50] <zeeshan> this is how i welded mine
[17:41:50] <PetefromTn_> they have thick aluminum fixture jigs for the headers.
[17:41:52] <ssi> furrywolf: tn has some pretty rugged areas, but no not as much as ca
[17:42:03] <zeeshan> a pro fabricator that i have been recently talking to
[17:42:06] <zeeshan> told me that is the problem
[17:42:10] <zeeshan> the fact that it's aluminum.
[17:42:25] <zeeshan> aluminum causes the manifold to be nonuniformly heated
[17:42:36] <Rab> zeeshan, yeah, I was thinking of a bar of plate steel...1" thick or whatever.
[17:42:36] <zeeshan> he suggested grab 1" thick steel plate, and bolt it to that.
[17:42:41] <Rab> BOOM
[17:42:44] <zeeshan> and it should solve the problem

[17:43:34] <zeeshan> rab that might temporarily solve the problem
[17:43:38] <zeeshan> if yo uthink about it.
[17:43:47] <zeeshan> the material will still have residual stresses in it
[17:43:50] <zeeshan> so lemme give you a scenario
[17:43:59] <zeeshan> you bolt this to your car, it sees 1600F (turbo temps)
[17:44:00] <PetefromTn_> I don't see how a THICK aluminum jig fixture would cause any problems
[17:44:08] <zeeshan> now you gotta take it off the car
[17:44:12] <zeeshan> guess what happens? the manifold warps.
[17:44:21] <zeeshan> youve essentially post weld heat treated it
[17:44:23] <zeeshan> this is a very common problem
[17:44:26] <zeeshan> now you gotta get it machined
[17:44:41] <zeeshan> i think proper manifold process should be like this:
[17:44:52] <Rab> zeeshan, if it made it onto the customer's car, it's no longer your problem. ;)
[17:44:56] <zeeshan> bolt it to a jig -> weld -> post weld heat treat (650C 1 hour) - > machine
[17:44:58] <PetefromTn_> well I gotta go practice ;)
[17:45:01] <zeeshan> you have a bullet proof manifold
[17:45:14] <zeeshan> rab and thats how you get know as a crap fabricator
[17:45:27] <zeeshan> these manifolds arent cheap
[17:45:35] <zeeshan> a tubular style starts at $1200
[17:46:50] <zeeshan> rab i still think its worth trying the 1" steel plate idea
[17:46:53] <zeeshan> and seeing it through out
[17:47:00] <zeeshan> it doesnt cost much additional time
[17:47:07] <zeeshan> couple drilled holes and youre ready to go :)
[17:48:23] <Rab> zeeshan, sure. Think the jig can also be used as a pallet for oven heat-treating, or might that introduce problems with the jig?
[17:48:32] <zeeshan> there you go
[17:48:34] <Rab> I guess you heat treat in an oven?
[17:48:36] <zeeshan> EVEN better idea!!!!!!!!1
[17:48:41] <zeeshan> heat treat it as one assembly
[17:48:44] <zeeshan> no more residual stresses
[17:48:47] <zeeshan> perfect

[17:59:16] <malcom2073> heh, "If you have the right hardware" I think he means a LinuxCNC PC with a mesaboard? ;)
[18:00:28] <skunkworks_> you can rigid tap with the printer port using linuxcnc....
[18:00:32] <zeeshan> skunkworks: you love stirring the poops up on mach forums :-)
[18:00:37] <zeeshan> i love it
[18:00:58] <malcom2073> skunkworks_: then "a linuxcnc pc" :P
[18:01:08] <zeeshan> skunkworks: you know your tapping videos
[18:01:15] <zeeshan> does the machine have a spindle brake
[18:01:22] <zeeshan> er braking resistor i mean
[18:01:40] <skunkworks_> I know what ones to post where.. (tormach rigid tapping using the mach3 replacment control)
[18:02:07] <skunkworks_> zeeshan: yes
[18:02:26] <zeeshan> okay i need to really get one hooked up
[18:02:41] <zeeshan> i get variations of +.25 - .375" sometimes
[18:02:44] <zeeshan> at 250 rpm tapping
[18:03:01] <zeeshan> so blind holes is almost a no go
[18:03:27] <skunkworks_> right - our spindle is too heavy to stop quick even with a breaking resistor
[18:03:38] <ssi> I've had issues with that on the HNC
[18:03:47] <ssi> have to program less depth than I actually want because of decel overshoot
[18:04:02] <skunkworks_> I remember someone doing some fancy hal stuff that predicts the overshoot and adjusts accordingly. IIRC
[18:04:07] <ssi> fancy
[18:04:37] <Tom_itx> zeeshan, just weld em up and slide the flange across the shop floor to flatten it
[18:07:59] <ssi> yea, just stone it flat :D
[18:08:45] <zeeshan> skunkworks: problem is it isn't consistent
[18:08:49] <zeeshan> sometimes its .125
[18:08:52] <zeeshan> sometimes its .375
[18:08:55] <zeeshan> its all over the place
[18:08:56] <skunkworks_> ah
[18:09:14] <zeeshan> does the same thing for say a m8 tap
[18:09:16] <zeeshan> amd m4 tap
[18:09:18] <zeeshan> *and
[18:09:31] <skunkworks_> how are you controlling the spindle?
[18:09:37] <zeeshan> modbus
[18:09:42] <zeeshan> maybe that is why?
[18:09:46] <skunkworks_> maybe
[18:09:50] <zeeshan> i do notice a lag between setting a speed
[18:09:58] <zeeshan> and actually observing it
[18:10:03] <zeeshan> and that lag is random
[18:10:15] <skunkworks_> that would be my thought.
[18:10:27] * zeeshan blames userspace component
[18:10:51] <Tom_itx> you sure it's random or just not figuring out the pattern yet
[18:11:02] <zeeshan> Tom_itx seems pretty random to me
[18:11:05] <Tom_itx> few things in life are random
[18:11:19] <zeeshan> remember when i was doiung that 226 hole plate

[18:11:56] <zeeshan> its not real time
[18:12:01] <zeeshan> type = time
[18:12:05] <Tom_itx> oh
[18:12:20] <Tom_itx> write a comp for it in realtime
[18:12:31] <zeeshan> all my code is in python
[18:12:33] <zeeshan> i dont think that'll be easy
[18:12:55] <zeeshan> i can't use a standard modbus library either
[18:13:04] <zeeshan> because the communication protocol isn't modbus
[18:13:11] <zeeshan> its some random protocol that hitachi made up
[18:13:28] <zeeshan> very similar, but the return codes are different
[18:13:33] <zeeshan> the function codes are also diff
[18:16:39] <skunkworks_> do you have an extra analog output and does your vfd take analog in?
[18:17:37] -!- toner [toner!~ink@c-67-180-228-85.hsd1.ca.comcast.net] has joined #linuxcnc
[18:17:46] <zeeshan> i do have a free spindle out
[18:17:50] <zeeshan> i think. lemme check
[18:19:48] <zeeshan> yep got a free analog output for the spindle on the 7i77
[18:20:11] <zeeshan> vfd takes -10 to 10v analog in
[18:20:27] <zeeshan> and the reverse and forward can be setup for sink or source
[18:20:32] <skunkworks_> something to try when you have time to see if it is more responsive
[18:20:37] <zeeshan> so i guess i can hook up the gpio directly to reverse?
[18:20:59] <Tom_itx> the analog out puts out a swing of 0v
[18:21:00] <Tom_itx> 10
[18:21:06] <Tom_itx> not 20
[18:21:25] <zeeshan> wut
[18:21:28] <zeeshan> the 7i77 ouytputs
[18:21:30] <zeeshan> -10 to 10v
[18:21:41] <skunkworks_> +/-10v
[18:21:44] <skunkworks_> :)
[18:21:47] <Tom_itx> hmm that must be different than the one on the 7i47s
[18:21:59] <Tom_itx> i understood it to have a 10v range
[18:22:07] <zeeshan> the thing i always get thrown off and have to do further research is
[18:22:21] <zeeshan> what kind of voltage level are they expecting o nthe vfd for source or sinking
[18:22:34] <zeeshan> like if i hook up 24vdc using the mesa gpio
[18:22:38] <zeeshan> will it blow up the vfd
[18:22:53] <zeeshan> it seems to be not written explicitly
[18:23:28] <zeeshan> nm
[18:23:29] <zeeshan> found it!
[18:23:41] <zeeshan> allowable maximum voltage = 27V, input impedance 4700 ohm
[18:24:28] <Tom_itx> wonder why the spindle circuit is different on those boards
[18:24:49] <zeeshan> Tom_itx: i think most servo drives are +/- 10v
[18:24:55] <zeeshan> i know the amc is
[18:25:01] <Tom_itx> i'm not saying they're not
[18:25:26] <Tom_itx> this one would likely not work on yours
[18:26:21] <Tom_itx> The voltage supplied between ANALOG+ and ANALOG- must be
[18:26:22] <Tom_itx> between 5VDC an 15VDC with ANALOG + always being more positive than ANALOG-.
[18:26:46] <Tom_itx> that's a 10v range on mine
[18:27:57] <zeeshan> hm
[18:31:14] <zeeshan> sourcing and sinking damn you
[18:31:15] <zeeshan> always confusing me
[18:32:11] <zeeshan> it looks like it's 3 physical wires to get forward/reverse + start/stop -- 1 wire goes to 0v rail of 24vdc supply, and then 2 wires directly from each gpio on the 7i77 to the vfd
[18:33:19] <skunkworks_> Tom_itx, I think that is a different beast
[18:34:03] <skunkworks_> the 7i77 has a spindle drive output (like a servo drive output) +/-10v

[19:33:59] <zeeshan> ROTARTY!!!
[19:34:06] <PetefromTn_> yeah
[19:34:11] <zeeshan> that looks like thin wall piping
[19:34:13] <zeeshan> thats hard to work with
[19:34:17] <PetefromTn_> but they are making more than just rotary now
[19:34:25] <PetefromTn_> no it is schedule 40
[19:34:28] <zeeshan> really?
[19:34:29] <PetefromTn_> thick as hell really
[19:34:37] <Deejay> nice welding
[19:34:44] <PetefromTn_> it's not bad really

[19:35:33] <PetefromTn_> yup like that
[19:35:39] <PetefromTn_> they just cut and weld
[19:35:40] <zeeshan> jthornton: they are cast
[19:36:33] <PetefromTn_> they are apparently using die grinders with sanding disks to polish the texture out of the pipes
[19:36:42] <PetefromTn_> then 3m disks to finish it off
[19:36:48] <zeeshan> belt sander
[19:36:49] <PetefromTn_> then Tig welding it all together
[19:36:53] <zeeshan> the portable kind
[19:36:58] <PetefromTn_> apparently not
[19:37:10] <zeeshan> this thing
[19:37:13] <PetefromTn_> they gave me a big box of 3m scotch brite and sanding disks
[19:37:20] <zeeshan> theres one where its a belt you can warp around

[19:37:53] <zeeshan> F that though

[19:38:05] <zeeshan> it someone really wants it that bad
[19:38:07] <PetefromTn_> whaddya mean?
[19:38:08] <zeeshan> they can pay 100$
[19:38:13] <zeeshan> to get it polished at a polisher
[19:38:33] <PetefromTn_> yeah no these guys want it pretty
[19:38:49] <PetefromTn_> I have been playing with ways to polish it up it takes a bit of time
[19:38:51] <ssi> polishing isn't that hard
[19:38:57] <zeeshan> ssi it is for this material
[19:39:00] <zeeshan> normal tube no
[19:39:04] <PetefromTn_> actually that 3m wheel I just bought works pretty well...
[19:39:06] <zeeshan> but you gotta really get the cast pattern off
[19:39:09] <zeeshan> take a long time
[19:39:15] <zeeshan> dirty ,. nasty work :P
[19:39:37] <malcom2073> Why is that dude sticking his middle finger in that sander handle? That just looks like a good way to lose a finger should it take off somewhere
[19:39:37] <zeeshan> at least its not aluminum
[19:39:51] <zeeshan> scratches just by looking at it :DD
[19:39:52] <PetefromTn_> I THINK they are cutting and fitting the pieces, then polishing, then tig welding them together
[19:40:14] <zeeshan> PetefromTn_: yes
[19:40:25] <zeeshan> otherwise there would be no color on the manifold
[19:40:27] <zeeshan> if they did it after
[19:40:33] <PetefromTn_> yup
[19:40:36] <malcom2073> Heh my grandfather used to call dents/scratches in aluminum the "union mark", since invariably they would get dropped at least once at this (union) work
[19:40:44] <PetefromTn_> easier to polish the pieces beforehand anyway

[19:47:08] <zeeshan> you can crimp it
[19:47:14] <zeeshan> but at least put some aluminum in between!
[19:47:28] <PetefromTn_> yeah even some 1/8 inch plate would help
[19:47:29] <zeeshan> that is an easy fiox though
[19:47:32] <zeeshan> dab some weld in it
[19:47:33] <zeeshan> and polish it out

[19:57:38] <zeeshan> just the manifold?
[19:57:45] <zeeshan> exhaust manifold like youre showing?
[19:58:02] <PetefromTn_> yeah the whole manifold tubing/plates, welded up etc?
[19:58:29] <zeeshan> production run
[19:58:30] <zeeshan> or one off
[19:58:46] <PetefromTn_> whatever
[19:58:54] <zeeshan> it makes a big diff =P
[19:59:09] <PetefromTn_> I doubt anyone makes these in any real numbers
[19:59:29] <zeeshan> the cheapo stuff goes for 550$
[19:59:41] <zeeshan> and by cheapo i mean thin wall garbage
[19:59:50] <zeeshan> the high end stuff goes for 1000
[19:59:56] <PetefromTn_> no I am talking schedule 40 like this...
[20:00:04] <zeeshan> im giving you a range of prices
[20:00:06] <zeeshan> to give you a feel for it
[20:00:07] <fenn> how much to get it laser sintered from titanium powder i wonder
[20:00:08] <PetefromTn_> with mild steel flanges ready to bolt up
[20:00:25] <zeeshan> if you wanna be competitive
[20:00:27] <zeeshan> $800
[20:00:32] <zeeshan> to 850
[20:00:35] <PetefromTn_> that sounds about right
[20:00:45] <PetefromTn_> I have NO IDEA what they are charging for them
[20:00:54] <zeeshan> easily that
[20:00:57] <PetefromTn_> it's a bunch of work I will tell you
[20:00:59] <zeeshan> but pete this is production run
[20:01:05] <zeeshan> for a specific turbo setup
[20:01:08] <zeeshan> if you're getting this random guy
[20:01:15] <zeeshan> who wants this huge custom turbo on his car
[20:01:20] <zeeshan> youre not gonna charge him 850
[20:01:22] <zeeshan> itll be around 1500
[20:01:24] <zeeshan> easily.
[20:01:25] <PetefromTn_> sure
[20:01:31] <zeeshan> you need to make custom jig etc
[20:01:41] <PetefromTn_> I am going to be making them..
[20:01:50] -!- Chopper79 [Chopper79!~Chopper@104.235.125.218] has joined #linuxcnc
[20:01:57] <PetefromTn_> apparently the guy who made these just drilled into his welding table and fixtured off of it LOL
[20:02:05] <zeeshan> this is considered the best manifold for the rx7
[20:02:07] <zeeshan> for a t4 turbo:
[20:02:11] <zeeshan> http://www.full-race.com/store/turbo-manifolds/mazda-rx7-fd-13b-twinscroll-turbo-manifold.html
[20:02:16] <zeeshan> its robotically welded
[20:02:42] <PetefromTn_> interesting
[20:03:04] <PetefromTn_> his is not all that far from that considering it was hand done and one off
[20:03:30] <zeeshan> yep
[20:03:44] <zeeshan> if someone is trying to get a custom manifold built cause its cheaper
[20:03:47] <PetefromTn_> how could that be robot welded
[20:03:47] <zeeshan> i steer them away
[20:03:52] <XXCoder> stary with casting then trim it away
[20:04:30] <PetefromTn_> interesting that has dual BOV's
[20:04:41] <zeeshan> PetefromTn_: trust me!!
[20:04:45] <zeeshan> full race is known for that
[20:04:50] <zeeshan> they are the industry leader in manifolds
[20:05:18] <zeeshan> http://www.full-race.com/prototype/weld/DSC00001.JPG
[20:05:21] <zeeshan> inside looks like that
[20:05:25] <zeeshan> its a perfect weld in every way
[20:05:26] <zeeshan> lol
[20:05:31] <PetefromTn_> nice
[20:05:43] <PetefromTn_> well I guess I have something to aim for now hehe

[20:06:29] <zeeshan> :{
[20:06:40] <ssi> so glad I don't do cars anymore
[20:07:09] <XXCoder> zeeshan: 900 cents cheap
[20:07:16] <fenn> why do people care what the welds look like
[20:07:18] <PetefromTn_> hehe
[20:07:26] <zeeshan> fenn: cause it matters
[20:07:36] <zeeshan> USUALLY
[20:07:42] <zeeshan> a good weld means good prep and good penentration
[20:07:48] <zeeshan> 80% of the time i'd say
[20:07:52] <PetefromTn_> it's funny the guy went out of his way to put his name on that one
[20:07:56] <zeeshan> LOL PetefromTn_
[20:07:57] <zeeshan> hahaha
[20:08:01] <CaptHindsight> looks all bent up and stuff
[20:08:05] <fenn> do exhaust tubes crack at the welds from poor penetration?
[20:08:08] <zeeshan> wow i choked on my water
[20:08:13] <zeeshan> fenn: hell yes
[20:08:15] <XXCoder> and termal chacking
[20:08:16] <zeeshan> especially in a turbo car
[20:08:31] <XXCoder> cant type worth crap today
[20:08:40] <PetefromTn_> just today?
[20:08:49] <PetefromTn_> ;)
[20:08:50] <XXCoder> yes
[20:08:55] <XXCoder> heh
[20:09:15] <fenn> why are the flanges so thick?
[20:09:33] <XXCoder> to stand to abuse im sure
[20:09:43] <CaptHindsight> anti-warp technology
[20:09:57] <zeeshan> hahaha CaptHindsight

[20:11:11] <CaptHindsight> zeeshan: is that SS?
[20:11:18] <PetefromTn_> I need a kickstarter for my whole damn whop LOL
[20:11:31] <PetefromTn_> shop
[20:11:40] <fenn> http://www.toxicfab.com/33-billet-stock-replacement-manifold lots of tool marks
[20:11:54] <zeeshan> holy shit
[20:11:59] <zeeshan> that is a sexy collector
[20:12:08] <PetefromTn_> yeah that guy is a master
[20:12:08] <XXCoder> I still remember that stupid famous guy having kickstarter for $40k music thingy
[20:12:17] <zeeshan> PetefromTn_: you werent kidding
[20:12:18] <zeeshan> this guy is good
[20:12:18] <XXCoder> it utterly failed because that guy is millionaire :P
[20:12:30] <PetefromTn_> that is NOT robot welded hehe

[20:13:30] <CaptHindsight> http://www.toxicfab.com/templates/clarente/images/slide2.jpg
[20:13:30] <PetefromTn_> yeah but look at it....
[20:13:38] <PetefromTn_> it's freaking glorious!
[20:13:48] <zeeshan> hey look!
[20:13:51] <zeeshan> he machined the flange
[20:13:52] <zeeshan> nice.
[20:13:55] <fenn> machining the part next to the flange as one piece looks like the right strategy
[20:13:56] <zeeshan> so guy deals with warping too
[20:13:57] <zeeshan> its not only me
[20:14:17] <zeeshan> fenn: collector
[20:14:19] <PetefromTn_> everyone deals with that
[20:14:20] <fenn> could make the flange a lot thicker and still save on weight vs just welding onto a flat plate
[20:14:30] <PetefromTn_> yeah it is a one piece collector
[20:14:34] <PetefromTn_> 3d machined
[20:14:44] <zeeshan> fenn: if you're building a manifold on a turbo car for weight
[20:14:51] <zeeshan> you wouldn't be using stainless steel
[20:14:53] <zeeshan> youd be using inconel
[20:14:55] <zeeshan> like f1

[20:15:58] <XXCoder> jeee
[20:16:04] <XXCoder> why weld so many times
[20:16:08] <XXCoder> wy not pipe bender?
[20:16:16] <zeeshan> 2 reasons
[20:16:17] <PetefromTn_> too tight
[20:16:18] <zeeshan> 1. ricer factor
[20:16:21] <zeeshan> 2. tight radius
[20:16:27] <fenn> showing off
[20:16:45] <XXCoder> ricer factor?
[20:16:48] <zeeshan> yes
[20:16:51] <zeeshan> like showing off
[20:16:55] <XXCoder> ah
[20:16:59] <zeeshan> for no good reason :P

[20:18:50] <PetefromTn_> you said you were using er309L
[20:19:14] <zeeshan> for mild steel to stainless yes
[20:19:20] <fenn> do people use D shaped tubing for higher flow rate?
[20:19:22] <zeeshan> and 308l for stainless to stainless
[20:19:37] <fenn> or is it easier to just use a huge diameter round tube

[20:20:34] <zeeshan> 1/16
[20:21:01] <PetefromTn_> props man that looks beautiful
[20:21:05] <zeeshan> thanks man!!
[20:21:16] <CaptHindsight> why all these washing machine engines? Is the charm getting a few more HP from your wind up toy? :)
[20:21:17] <XXCoder> yeah nice work
[20:21:22] <fenn> zeeshan: gases want to travel the shortest distance possible so they hug the inside of corners more than the outside; for the same cross sectional area of a curved tube you get more flow from a D shaped section than a round section
[20:21:27] <PetefromTn_> just fusion welds it looks like
[20:21:52] <zeeshan> fenn: i dont believe you
[20:22:07] <zeeshan> PetefromTn_: yes for sure on ic piping i dont filler it
[20:22:08] <zeeshan> not needed
[20:22:24] <zeeshan> 4 feet of downpipe after the turbo i use filler
[20:22:25] <zeeshan> after that i dont
[20:22:28] <CaptHindsight> http://www.netikka.net/vepiku/pakosarja/hitsattuna.JPG more ugly welds

[20:27:05] <zeeshan> CaptHindsight: a lot
[20:27:14] <zeeshan> this is what kind of pushed me to machining
[20:27:21] <zeeshan> its less abusive to your body
[20:27:33] <zeeshan> with fabrication, it really takes a toll on you
[20:27:38] <zeeshan> i still do it, but i dont do it for cheap anymore

[20:28:52] <PetefromTn_> apparently they have a bunch of ideas for me for machining stuff for it.. Hopefully anyways.
[20:29:10] <zeeshan> hope y ou get em
[20:29:22] <XXCoder> zeeshan: funny thing, machining is abusing my body a bit, standing 10 hours a day isnt good for my lready bad back
[20:29:30] <XXCoder> and ankles hurt a bit lol
[20:29:34] <zeeshan> XXCoder: i dont mean production machining
[20:29:36] <PetefromTn_> hopin'
[20:29:40] <zeeshan> i mean prototype machining
[20:29:40] <zeeshan> :)
[20:29:43] <XXCoder> lol ok

[20:29:55] <zeeshan> i know how it feels
[20:30:03] <zeeshan> on continental shift
[20:30:10] <zeeshan> basically when the operator called in sick
[20:30:18] <zeeshan> i'd have to fill in, even though it wasn't my job description
[20:30:31] <zeeshan> 12 hours sometimes 5 days in a row!!
[20:30:41] <zeeshan> i don't know how you do it :)
[20:30:46] <zeeshan> i couldn't. i quit
[20:31:14] <XXCoder> some days it isnt good
[20:31:20] <PetefromTn_> there's some solid work on that JDM link
[20:31:40] <XXCoder> this week definitely wasnt. im making hose guide, I can make around 50 a day and theres 200 in order
[20:32:03] <zeeshan> XXCoder: thats another thing
[20:32:08] <zeeshan> it's not like you can hide your numbers
[20:32:21] <zeeshan> if you dont produce something
[20:32:28] <zeeshan> you get caught
[20:32:34] <zeeshan> the only time you get lucky is if the machine breaks down :P
[20:32:35] <XXCoder> im kind of sick (my body sucks in specific way, it has lousy defense against illness but very strong fight) means I get sick often but short
[20:32:53] <zeeshan> are you breathing in coolant?
[20:33:03] <XXCoder> not very much
[20:33:11] <XXCoder> usually hold breath as I spray em off
[20:33:23] <zeeshan> yes but thers always the smell in the air
[20:33:25] <XXCoder> whats symtoms of that
[20:33:30] <zeeshan> feeling sluggish
[20:33:31] <zeeshan> lazy
[20:33:32] <zeeshan> tired
[20:33:33] <zeeshan> fatigued
[20:34:05] <XXCoder> hmm some of those
[20:34:05] <zeeshan> it could be anything when you get those symptoms
[20:34:11] <XXCoder> plus headache and dizzyness
[20:34:13] <zeeshan> but i noticed i got a lot better after 2 months of quitting
[20:34:27] <zeeshan> but i was also doing night shift
[20:34:30] <zeeshan> which i think takes a toll on you
[20:34:39] <XXCoder> I cant smell unfortunately
[20:34:42] <zeeshan> lol
[20:34:49] <zeeshan> so you dont even know!
[20:34:50] <ssi> I smell unfortunately sometimes
[20:34:53] <XXCoder> swing here, 3:15 pm to 1:45 am
[20:35:10] <zeeshan> i chose night shift cause boy during the summer time
[20:35:14] <zeeshan> a machine shop is the worst place to be
[20:35:21] <zeeshan> 50C air blowing from the damn machine
[20:35:21] <zeeshan> hot shnips
[20:35:24] <zeeshan> *chips
[20:35:31] <ssi> shnips
[20:35:41] <fenn> yum
[20:35:56] <XXCoder> zeeshan: lol yeah during very hot week I had fan very close to me and pointing in such way that hot air dont get to my face
[20:36:04] <fenn> sorry zeeshan i can't find the old article about intake porting that explained D-shaped manifold cross sections
[20:36:10] <XXCoder> machine air probably reached 110F
[20:36:18] <fenn> internet has gone downhill this past decade...
[20:36:19] <XXCoder> it was very hard metal job
[20:36:21] <zeeshan> fenn: youre probably thinkign of intake manifolds
[20:36:23] <zeeshan> plenums
[20:36:26] <zeeshan> where that is beneficial
[20:36:29] <XXCoder> so lots heat since first step dont even use coolant
[20:36:31] <fenn> yes but it's all the same physics
[20:36:33] <zeeshan> i dont thin kthat is beneficial at all for transport
[20:36:36] <zeeshan> of fluids
[20:36:41] <zeeshan> the boundary layer is huge
[20:36:55] <zeeshan> youre going to get massive turbulence at the corners of the square to round
[20:37:09] <zeeshan> i can quickly do a simulation between the two
[20:37:18] <zeeshan> you said cross section area is constant?
[20:37:33] <fenn> it's not square, it's like a capital D but with lightly rounded corners
[20:37:48] <zeeshan> still
[20:38:00] <fenn> it would be hard to fabricate by welding
[20:38:22] <fenn> you couldn't just weld cut sections together
[20:38:33] <fenn> so that's probably why it isn't used
[20:38:45] <CaptHindsight> zeeshan: how many hours to fab a custom header?
[20:39:48] <zeeshan> fenn: i think its relatively easy to make!
[20:39:52] <zeeshan> just crush one end :P
[20:40:07] <zeeshan> CaptHindsight: it so depends man
[20:40:24] <zeeshan> for a rx7 typically 10-12 hours
[20:40:31] <zeeshan> like solid welding and fabrication
[20:40:38] <zeeshan> if you already have a jig made
[20:40:44] <FinboySlick> CaptHindsight: Don't trust his opinion, he took out the wankel.
[20:41:00] <CaptHindsight> zeeshan: is that because you have already made them, so less design time?
[20:41:09] <zeeshan> yes
[20:41:12] <zeeshan> youre not sitting there on the car
[20:41:18] <zeeshan> trying to figure out where the wastegate needs to go, turbo etc
[20:41:27] <zeeshan> its a lot of little considerations
[20:41:35] <zeeshan> the way the oil comes inand goes out
[20:41:36] <zeeshan> etc
[20:41:44] <ssi> when I ordered the exhaust for my RV7 from Vetterman, I called him and told him that I had a kinda goofy non-standard setup (a C1C with the sump machined to be a forward facing induction)
[20:42:01] <ssi> he said "yeah, I've done a couple of those back in the 80s. It'l gonna cost you a bit more because I have to set up my fixtures for it"
[20:42:05] <ssi> I said sure, how much?
[20:42:10] <ssi> "eh.. about $20 extra"
[20:42:11] <ssi> lololol
[20:42:32] <ssi> $995 instead of $975
[20:42:45] <zeeshan> lol
[20:42:47] <zeeshan> what
[20:43:13] <zeeshan> fenn: plz answer me
[20:43:20] <zeeshan> is the cross sectional area constant between the two shapes?
[20:43:25] <ssi> https://scontent-atl1-1.xx.fbcdn.net/hphotos-xfa1/v/t1.0-9/418705_896858077772_1916825954_n.jpg?oh=a47ce49e7daf45772f654964d78fe904&oe=564B6D7C
[20:43:40] <fenn> yes the point is that the D is better for a given area
[20:43:48] <fenn> in curved tubing
[20:44:21] <zeeshan> is the flat part on the inner side
[20:44:25] <zeeshan> logically thats the only place it'd make sense
[20:44:31] <zeeshan> inner side of the curvuture
[20:44:34] <fenn> yes the flat part is on the shorter radius
[20:44:40] <ssi> k going home bye suckas
[20:44:42] <zeeshan> okay i can see that being better
[20:44:48] <zeeshan> in a straight pipe no
[20:44:51] <zeeshan> bend pipe yes
[20:45:28] <zeeshan> i also intuitively feel like the transition from round to D right before the bend
[20:45:34] <zeeshan> would neglect the benefits of it
[20:45:56] <zeeshan> if you do come across that paper, id like to read about it
[20:46:42] <fenn> it was probably on this site somewhere
http://theoldone.com/articles/default.asp
[20:47:09] <zeeshan> oldone knows it all
[20:47:11] <zeeshan> great site
[20:48:56] <SpeedEvil> Just remember to hone it after installation.

[20:49:58] <XXCoder> wouldnt it also hit pistons and such?
[20:50:01] <zeeshan> thats the die i would use
[20:50:05] <zeeshan> to make your D shapes tube
[20:50:09] <zeeshan> its very doable
[20:50:29] <zeeshan> you play with the hemisphere height to get it correct
[20:50:46] <zeeshan> might also need to fill the tube with sand
[20:51:27] <fenn> heh "hit it with a hammer"
[20:51:54] <fenn> i think you'd want a D-shaped mandrel and draw the tube over the mandrel
[20:52:13] <fenn> you'd probably want left and right hand twist versions too
[20:52:49] <SpeedEvil> I like the 'balloon animals with pressure-washer' approach
[20:52:55] <fenn> yeah that's cool
[20:53:08] <SpeedEvil> But probably not acceptable for cosmetically important stuff
[20:57:10] <fenn> so are those elbows investment cast?
[20:57:16] <zeeshan> yes
[20:57:29] <zeeshan> depends on the manufacturer though!
[20:57:35] * XXCoder facepalms. https://i.chzbgr.com/maxW500/7927345920/h095473BD/
[20:57:44] <fenn> can't they just investment cast the entire header?
[20:57:52] <zeeshan> fenn ofcourse
[20:57:56] <zeeshan> do you wanna pay for one though? :)
[20:58:10] <zeeshan> i have considered 3d printing a mold
[20:58:12] <zeeshan> and getting it cast
[20:58:18] <zeeshan> never got around to it though
[20:58:18] <fenn> it seems easier to glue together some wax bits than to weld the pieces cast from the same patterns
[20:58:42] <zeeshan> youre assuming that you already know what your end product looks like
[20:58:48] <zeeshan> most car stuff you gotta fit it on the car.
[20:58:54] -!- FinboySlick has quit [Quit: Leaving.]
[20:59:01] <zeeshan> you need at least a prototype before i think you can cast it
[21:03:21] <CaptHindsight> sand cast vs investment casting
[21:04:16] <CaptHindsight> thin tubes would be difficult to sand cast
[21:04:53] <CaptHindsight> so the parts would use more material and be heavier
[21:05:26] <fenn> well they already use cast tubes apparently
[21:06:25] <CaptHindsight> separate tubes that are welded?
[21:06:29] <fenn> here's a passing mention of D-shaped manifold tubing

http://www.ticotitanium.com/wp-content/themes/tico/images/product-photos/titanium_elbow_long_fullsize.jpg
[21:09:08] <fenn> but in stainless presumably
[21:09:18] <CaptHindsight> inkjet could make a header size sand mold in a couple/few hours
[21:09:34] <fenn> why sand
[21:10:16] <fenn> anyway yeah selective inhibition sintering or something like that seems like a way to do it
[21:11:11] <CaptHindsight> multi-LCD SLA could make a water rinse out pattern for investment in <1 hour
[21:11:23] <XXCoder> fenn: to preserve volume
[21:11:35] <XXCoder> prevents bending inwards for example
[21:11:47] <SpeedEvil> https://www.youtube.com/watch?v=E7--ZWPVVdQ
[21:11:54] <SpeedEvil> e-beam sintering
[21:11:59] <fenn> XXCoder: we are talking about sand molds for casting
[21:12:23] <XXCoder> oh thought you was referring to earlier zee comment of using sand for forming pipe into D
[21:12:24] <CaptHindsight> I'm just comparing times to make molds or patterns
[21:13:12] <fenn> SpeedEvil: looks like a 1970s music video
[21:13:25] <SpeedEvil> :)
[21:15:20] <fenn> they never show the part being made
[21:17:44] <CaptHindsight> it have to be multi ebeam sintering for it to take less than a day or two
[21:17:59] <CaptHindsight> I bet there is a patent blocking it
[21:18:54] <SpeedEvil> fenn: yeah - they're missing out the whole 'brush on new layer' bit
[21:25:46] <CaptHindsight> SLA printed water rinse out patterns of each tube for investment casting then welded to final shape is probably fastest and lightest final form
[21:26:24] <CaptHindsight> inkjet sand cast if you don't mind the extra material and weight

[22:23:52] <PetefromTn_> just screwing around practicing today while the machine is running.
[22:24:42] <zeeshan> :D
[22:25:41] <PetefromTn_> http://i.imgur.com/fASTUkY.jpg Can't seem to get used to this diameter of tubing and get a good method
[22:26:49] <Loetmichel> looks like a vERY presentable weld to me
[22:26:54] <zeeshan> thats actually good dude
[22:27:05] <zeeshan> what amp are you welding at
[22:27:14] <PetefromTn_> not nearly good enough unfortunately
[22:27:22] <zeeshan> tell em to fak off
[22:27:24] <PetefromTn_> I think its set to 125
[22:27:26] <zeeshan> if they cant live with that
[22:27:30] <zeeshan> thats better than the other guys
[22:27:30] <zeeshan> lol
[22:27:47] <PetefromTn_> http://i.imgur.com/qVOiJCA.jpg
[22:27:48] <andypugh> I have been MIG welding galvanised stuff all evening. I will find out later if I have poisoned myself again.
[22:27:59] <zeeshan> andypugh: why would you do that to yourself?
[22:28:07] <PetefromTn_> that is about the best one so far
[22:28:16] <zeeshan> what filler
[22:28:18] <zeeshan> what cup
[22:28:19] <PetefromTn_> I just can't seem to get comfortable
[22:28:32] <PetefromTn_> well I am using ER308L rod
[22:28:39] <PetefromTn_> but its 3/32
[22:28:47] <zeeshan> thats fine for thick stuff
[22:28:59] <PetefromTn_> 3/32 2%lanthanated tungsten
[22:29:01] <zeeshan> the 1/16 i wasn't sure if i was clear about
[22:29:05] <PetefromTn_> sharpened to a point
[22:29:07] <zeeshan> was for 1/16 thin wall stuff
[22:29:27] <zeeshan> looks good to me
[22:29:31] <PetefromTn_> I have a BIGASS gas lens setup with a HUGE long cup don't remember what size
[22:29:35] <zeeshan> i think youre moving too fast
[22:29:38] <zeeshan> or too slow :P
[22:29:45] <PetefromTn_> thanks but it is not
[22:29:49] <PetefromTn_> oh
[22:29:50] <zeeshan> cause there is a bit of grey
[22:29:52] <PetefromTn_> maybe I dunno
[22:30:10] <PetefromTn_> yeah I am not sure what is causing that
[22:30:11] <zeeshan> did you touch your tungsten?
[22:30:13] <zeeshan> onto the weld puddle
[22:30:18] <PetefromTn_> dip it?
[22:30:20] <zeeshan> is that why there is a poof of iron oxide
[22:30:26] <zeeshan> around the weld
[22:30:40] <PetefromTn_> where?
[22:30:44] <zeeshan> http://i.imgur.com/qVOiJCA.jpg
[22:30:46] <zeeshan> on the right
[22:30:53] <zeeshan> there is a poof cloud of orange
[22:30:53] <PetefromTn_> Honestly I would LOVE some good tips here
[22:30:54] <zeeshan> around the weld
[22:31:11] <zeeshan> that happens usually from touching your tungsten in the puddle
[22:31:14] <zeeshan> or not enough gas flow
[22:31:15] <PetefromTn_> dunno I don't think I did but I may have
[22:31:26] <PetefromTn_> I have the flow set to like 23
[22:31:33] <zeeshan> that is fine
[22:31:51] <zeeshan> something happened there
[22:32:01] <zeeshan> you woulda heard a weird arcing thing going on
[22:32:12] <zeeshan> you didnt step on the tig hose did ya
[22:32:14] <PetefromTn_> if I could get a little bit more consistent I think they would be okay with it until I can get my skills back in shape
[22:32:23] <PetefromTn_> LOL no
[22:32:26] <zeeshan> looks consistent enough to me dude
[22:32:29] <zeeshan> :)
[22:32:42] <zeeshan> looks like you wandered a little bit
[22:32:45] <zeeshan> cause you couldnt see the gap
[22:32:50] <zeeshan> but its not a huge wander
[22:32:51] <PetefromTn_> like I said when I stop and start things go screwey
[22:33:23] <PetefromTn_> big problem is I am running out of material to practice on here
[22:33:30] <zeeshan> cut it up
[22:33:33] <zeeshan> and start again!!
[22:33:34] <zeeshan> :D
[22:33:34] <PetefromTn_> they just gave me a couple elbows and pieces...
[22:33:36] <zeeshan> you got a 7x12
[22:33:38] <PetefromTn_> yeah I am doing that
[22:33:54] <zeeshan> heres a tip for you
[22:33:57] <zeeshan> cause im a CHEAP bastard
[22:33:58] <PetefromTn_> but I was thinking the welded areas are probably sorta contaminated for future welds no?
[22:34:01] <zeeshan> and i won't ever buy a vertical bandsaw
[22:34:16] <zeeshan> well i mean cut it at the middle of the mandrel
[22:34:18] <zeeshan> bend
[22:34:26] <PetefromTn_> oh ok
[22:34:26] <zeeshan> away from the heat affected zone
[22:34:35] <zeeshan> do you know how to cut it? :P
[22:34:38] <zeeshan> i do a ghetto method
[22:34:40] <PetefromTn_> I have a vertical table made for the 7x12 I use
[22:34:41] <zeeshan> but it's worked for me ALL This time
[22:34:47] <zeeshan> you can do that :P
[22:34:53] <zeeshan> but im lazy remember
[22:34:58] <zeeshan> i dont like to do physical labor
[22:35:04] <andypugh> I would use a hacksaw, it would take less time than walking to the bandsaw.
[22:35:12] <zeeshan> andypugh: id love to see you do that
[22:35:14] <zeeshan> on 304
[22:35:20] <PetefromTn_> andypugh you must have arms like a gorilla
[22:35:22] <zeeshan> .140"+
[22:35:31] <zeeshan> i weld a bar to the weld elbow
[22:35:37] <zeeshan> like 3 tacks
[22:35:47] <zeeshan> and chip off the pieces as needed
[22:35:53] <zeeshan> (horizontal mode)
[22:36:13] <zeeshan> ghetto but works
[22:36:14] <zeeshan> :)
[22:36:19] <PetefromTn_> not following you
[22:36:31] <zeeshan> the problem is you cant hold the weld elbow in your horizontal vise
[22:36:41] <zeeshan> so i weld a square tube at the end of the weld elbow
[22:36:45] <zeeshan> so i can hold the square tube in the vise
[22:37:00] <zeeshan> and i angle the square tube by eye in the vise to align where i wanna cut the weld elbow
[22:37:09] <PetefromTn_> oh yeah I usually use the big screw I have tapped into the moving jaw to balance it
[22:37:16] <zeeshan> ah!
[22:37:38] <PetefromTn_> but I see what you are saying
[22:39:01] <PetefromTn_> http://i.imgur.com/fASTUkY.jpg here's another shot of that one..
[22:39:29] <PetefromTn_> it's not terrible but it is really not good enough... especially after looking at these other guys masterworks ;)
[22:39:49] <andypugh> I wonder if a backer inside the tube would help?
[22:40:04] <PetefromTn_> ?
[22:40:15] <andypugh> copper bar
[22:41:34] <PetefromTn_> I don't know but I don't have any here
[22:42:51] <zeeshan> andypugh: hes not welding thin stuff
[22:42:55] <zeeshan> its .140"
[22:42:58] <zeeshan> hes welding at 125A
[22:43:02] <zeeshan> hes not gonna blow through
[22:43:30] <PetefromTn_> thin stuff might actuallly be easier since you can just fuse it LOL
[22:43:41] <andypugh> Ah, 3.5mm? That’s pretty sturdy, yes.
[22:47:24] <PetefromTn_> zeeshan do you pulse with the pedal on this stuff?
[22:48:09] <zeeshan> i use the pulser on the tig
[22:48:16] <zeeshan> set to about 20 pulses per sec
[22:48:22] <zeeshan> but i dont think you really need it
[22:48:28] <PetefromTn_> for this stuff?
[22:48:31] <zeeshan> yes
[22:48:44] <zeeshan> it helps get you in the rhythm
[22:48:53] <zeeshan> and also "helps" with warping
[22:48:56] <zeeshan> "HELPS"
[22:48:56] <zeeshan> bs.
[22:48:58] <zeeshan> but yea :p
[22:52:57] <PetefromTn_> so basically looking at the picture of my crap welds what tips would you recommend?
[22:53:26] <andypugh> I wouldbe happy with those welds. But I am not selling anything.

[22:53:40] <zeeshan> pete try goiing faster
[22:53:47] <zeeshan> for your travel or slower
[22:54:06] <zeeshan> stainless will go grey if you go too fast or too slow
[22:54:10] <zeeshan> i almost think youre going to ofast
[22:54:12] <zeeshan> *too
[22:54:20] <PetefromTn_> I was thinking of increasing the heat and adding a touch more rod to flow out the puddle a bit more
[22:54:38] <zeeshan> you can try that just to see what happens for yourself
[22:54:44] <zeeshan> but i think the weld will go more grey
[22:54:50] <PetefromTn_> ok
[22:54:59] <PetefromTn_> I have been playing with different settings all afternoon
[22:55:08] <PetefromTn_> just trying to get a decent setup for this stuff
[22:55:25] <PetefromTn_> I agree tho that they look a bit chalky
[22:55:27] <zeeshan> im happy with your weld :)
[22:55:33] <zeeshan> thej only problem ispot is the rust
[22:55:34] <zeeshan> that formed
[22:55:41] <zeeshan> try to see why that happened
[22:56:20] <PetefromTn_> it did not do it on all of them so might have dipped it or something. I was keeping a pretty tight gap
[22:58:31] <PetefromTn_> I gotta do something better with my backpurge ghetto setup here LOL
[22:58:57] <PetefromTn_> do you use aluminum tape?
[22:59:15] <zeeshan> nope
[22:59:17] <zeeshan> no back purging
[22:59:22] <zeeshan> no tape
[22:59:30] <zeeshan> because i dont weld for 100% strength
[22:59:33] <zeeshan> i aim for 80%
[22:59:51] <PetefromTn_> even on that thin stuff?
[23:00:00] <zeeshan> yep
[23:00:12] <zeeshan> 45A for 65 thou
[23:00:20] <PetefromTn_> wow I would have thought it sugared pretty bad inside
[23:00:30] <zeeshan> nope
[23:00:43] <zeeshan> if you sit on it too long
[23:00:45] <zeeshan> itll surgar
[23:00:46] <zeeshan> *sugar
[23:00:50] <zeeshan> cause its penetrating too deep

[23:02:36] <PetefromTn_> they're payin' for the materials and gas so I don't care really but it does take longer that way
[23:03:21] <PetefromTn_> so you don't think a 1/16 tungsten would help for this tube then...
[23:03:26] <zeeshan> no
[23:03:29] <zeeshan> itll blow up
[23:03:41] <PetefromTn_> at 125?
[23:03:43] <zeeshan> yea
[23:03:50] <zeeshan> very close to blowing up
[23:03:50] <zeeshan> :P
[23:04:16] <PetefromTn_> well I guess I will just keep cutting and practicing
[23:04:32] <zeeshan> try your travel speed
[23:04:34] <PetefromTn_> hopefully I can get to a more consistent look

[23:06:20] <PetefromTn_> by prepped I take them, try to make them fit nice and tight, bevel the edges with the grinder, and deburr the insides, then I do some polishing on the outside like he did on that header pic I showed you.
[23:06:35] <zeeshan> sounds good
[23:06:46] <zeeshan> youre making me want to go lay some bead
[23:06:47] <zeeshan> lol
[23:06:51] <zeeshan> all this weld talk
[23:07:02] <PetefromTn_> I like it actually
[23:07:12] <PetefromTn_> I like it more when my welds look good ;)
[23:07:17] <zeeshan> hehe
[23:07:52] <andypugh> I bought a MIG for this job, and it’s definitely a job for MIG, but I didn’t enjoy it. Somehow TIG is more fun.
[23:08:09] -!- moorbo_ has quit []
[23:08:21] <PetefromTn_> yeah I have a cheapass mig here. Always tell myself I will get a nicer one but I almost never use it as it is LOL
[23:08:37] <zeeshan> i like mig
[23:08:40] <zeeshan> point and pray
[23:08:43] <zeeshan> gotta love
[23:08:43] <zeeshan> :D
[23:08:49] <PetefromTn_> spray and pray
[23:08:55] <zeeshan> lol
[23:09:13] <PetefromTn_> actually where I used to work they had a nice BIG Miler mig unit and it was pretty nice
[23:09:23] <PetefromTn_> I welded a bunch of stuff for them with that thing
[23:09:40] <PetefromTn_> it's easy to look good with a mig if you have ANY skills with a tig I think
[23:10:04] <zeeshan> to be honest with you
[23:10:09] <zeeshan> you might be suprised about this
[23:10:24] <zeeshan> but most people that don't know much about welding think tig welds look ugly
[23:10:34] <zeeshan> they dont like the coin pattern
[23:10:41] <PetefromTn_> blasphemy
[23:10:44] <zeeshan> yea man
[23:10:48] <zeeshan> engineers.. fkn tards
[23:10:53] <zeeshan> http://i.ytimg.com/vi/w4RrDeUKcH4/0.jpg
[23:11:01] <zeeshan> they think this is good looking
[23:11:05] <zeeshan> (i agree it is good looking for a mig)
[23:11:08] <PetefromTn_> it is
[23:11:10] <zeeshan> but cmon, tig is sexy!
[23:11:23] <PetefromTn_> it can be :P
[23:11:27] <zeeshan> haha
[23:15:03] <zeeshan> andypugh: have you done surface modelling
[23:15:09] <zeeshan> i have this project im working on for a person
[23:15:11] <zeeshan> its kicking my ass
[23:15:37] <andypugh> I guess not, as I am not sure what you mean :-)
[23:15:52] <PetefromTn_> you gonna probe that thing?
[23:16:00] <zeeshan> lol pete i should eh!
[23:16:05] <zeeshan> im actually doing it like this:
[23:16:09] <andypugh> You mean like CAD or multi-dimensional least-squares stuff?
[23:16:38] <zeeshan> http://i.imgur.com/heUAXGt.jpg
[23:16:42] <PetefromTn_> sounds like a good excuse to buy a decent probe LOL
[23:16:43] <zeeshan> http://i.imgur.com/5Ja054O.jpg
[23:16:54] <zeeshan> problem is it's clay
[23:16:57] <zeeshan> =/
[23:16:58] <andypugh> (I wrote some excel code to get a least-squares polynomial fit surface in up to 7 dimensions :-)
[23:16:58] <PetefromTn_> hey thats not bad
[23:17:06] <zeeshan> but its not making a surface right man
[23:17:08] <PetefromTn_> never thought of doing it that way
[23:17:10] <zeeshan> its all f'ed up
[23:17:21] <PetefromTn_> you can SLICE it
[23:17:22] <zeeshan> lol andypugh
[23:17:48] <zeeshan> so i use the left curve as a base
[23:17:51] <zeeshan> but the right curve
[23:17:53] <zeeshan> i should make more of them
[23:17:58] <zeeshan> and just make slices
[23:17:59] <andypugh> Lofting?
[23:18:01] <zeeshan> and then boundary
[23:18:11] <zeeshan> whatever method it is
[23:18:16] <zeeshan> i need to be able to play around with it later
[23:18:18] <zeeshan> cause itll transform a lot
[23:19:21] <andypugh> If you could actualy physically slice the original you should be able to slice between profiles. Make the profiles as splines, then you can edit them
[23:19:31] <zeeshan> i wish could do that
[23:19:32] <zeeshan> lol
[23:19:36] <zeeshan> i think he'd be pissed though

[23:20:10] <PetefromTn_> nice
[23:20:12] <zeeshan> those are some serious aluminum plates
[23:20:14] <zeeshan> on the bottom
[23:20:16] <zeeshan> $$$$$$
[23:20:18] <t12> hah yeah

[23:20:58] <t12> figured i needed to loadspread onto wood floor
[23:21:07] <t12> and gives me a good surface for the leveling feet that have yet to come
[23:22:20] <andypugh> zeeshan: So, you need to buy one of those 3D scanners. No option….
[23:23:20] <Tom_itx> we used a cmm once for that
[23:23:35] <Tom_itx> to measure some head pockets
[23:23:36] <zeeshan> lol andypugh
[23:23:37] <andypugh> I think he said this was too soft
[23:23:46] <zeeshan> its hard clay
[23:23:51] <zeeshan> non conductive though
[23:23:51] <Tom_itx> freeze it
[23:24:01] <zeeshan> i dont have a cmm or a 3d scanner
[23:24:04] <zeeshan> =P
[23:24:15] <andypugh> DO you have a mill and a probe and an A axis?
[23:24:15] -!- nofxx [nofxx!~nofxx@unaffiliated/nofxx] has joined #linuxcnc
[23:24:18] <Tom_itx> make a linuxcnc touch probe
[23:24:38] <andypugh> Make profiles in polar coordinates
[23:24:51] <zeeshan> i got a 3 axis mill
[23:24:52] <zeeshan> :P
[23:25:05] <zeeshan> the thing is i need to do this with splines
[23:25:06] <andypugh> You could use a manual 4th axis
[23:25:07] <zeeshan> cause this is just a base
[23:25:14] <zeeshan> itll change a lot
[23:25:16] <zeeshan> if i probe it
[23:25:17] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/emc/small_probe8_small.jpg
[23:25:18] <CaptHindsight> t12: did everything get scrapped?
[23:25:20] <zeeshan> wont it be unchangeable
[23:25:22] <Tom_itx> they're not hard to make
[23:25:23] <andypugh> Yeah, join the dots with splines, job done.
[23:25:23] <zeeshan> cause itll be a huge point cloud
[23:25:30] <zeeshan> ah
[23:25:43] <PetefromTn_> what do you need a fourth axis for?
[23:25:46] <andypugh> Make N “rings” then loft them
[23:25:53] <zeeshan> im trying andypugh
[23:25:54] <zeeshan> its hard

[23:32:35] <zeeshan> we made a car using it
[23:32:35] <t12> theres so many options
[23:32:38] <zeeshan> but its hard
[23:32:38] <t12> the technical work isnt hard
[23:32:43] <t12> its the business side thats difficult
[23:32:48] <t12> 100+ investors
[23:33:13] <Tom_itx> good luck keepin them all happy
[23:33:15] <PetefromTn_> investors? whats that? ;)
[23:33:55] <CaptHindsight> PetefromTn_: those are people that give you money in exchange for them being able to tell you what to do
[23:34:29] <CaptHindsight> mostly on the business side, they tend to not know any tech from magic

[23:40:24] <zeeshan> right?
[23:40:28] <andypugh> Yes
[23:40:35] <andypugh> (well, 4 actualy)
[23:40:50] <zeeshan> im not sure which way to slice this part
[23:40:53] <zeeshan> top to bottom
[23:40:54] <zeeshan> or sideways
