[00:00:06] <jdh> was the customers design? is it some known shape I just can't see?
[00:00:22] <Tom_itx> jdh, it's a polished turd
[00:00:23] <Jymmm> zeeshan: resin can be a bitch and dull cutters fast
[00:00:33] <zeeshan> its only acrylic
[00:00:40] <zeeshan> its not gonna do anything :P
[00:00:43] <PetefromTn_> no man not a polished turd...it's the VENUS DEMILO!!
[00:00:47] <Jymmm> wait... it's wood or acrylic?
[00:00:47] <zeeshan> ROFL PetefromTn_
[00:00:50] <renesis> melt onto your cutter
[00:00:57] <zeeshan> Jymmm: do you know what stablized wood is?
[00:01:01] <Rab> zeeshan, I don't smoke weed but that looks like a really cool project. You're pretty much obligated to give it a road test, you know. Nancy Reagan is dead.
[00:01:27] <Jymmm> zeeshan: I've seen it, but I'm asking what the polymer is being used?
[00:01:28] <renesis> i suspect its for nicotine juice, with the resevoir
[00:01:42] <zeeshan> Jymmm: its basically acrylated wood
[00:01:43] <renesis> doesnt look like something 510 threaded
[00:01:58] <Jymmm> zeeshan: spindle speed?
[00:02:01] <zeeshan> it is 510 threaded renesis
[00:02:12] <renesis> then i dont get the reservoir
[00:02:14] <zeeshan> Jymmm: im not going through this right now
[00:02:17] <zeeshan> maybe later
[00:02:19] <zeeshan> thank you though
[00:02:42] <zeeshan> renesis: i dont get a lot about it
[00:02:48] <zeeshan> im making it :P
[00:02:51] <zeeshan> its not my design
[00:02:52] <renesis> anyway if its 510 threaded you can use it for cannabis oil or almost anything
[00:02:55] <zeeshan> i just made it manufacturable
[00:03:04] <zeeshan> if you wanted to yea you could
[00:03:11] <Jymmm> renesis: 510 is all vaping =)
[00:03:11] <zeeshan> but it'd be a very expensive vape for that
[00:03:34] <renesis> it doesnt have the pocket for ego atomizers
[00:03:47] <zeeshan> with my cost + his wood cost + pcb + battery tubes etc
[00:03:54] <zeeshan> he's prolly selling these at 800 per piece
[00:03:54] <renesis> so wont work with common cannabis oil atomizers
[00:03:56] <zeeshan> to 650
[00:04:04] <renesis> ha wtf
[00:04:04] <zeeshan> its more for collection than using
[00:04:18] <zeeshan> just the stablized wood pieces are $150
[00:04:33] <zeeshan> if you wanted to smoke pot, you'd go pick yourself up a $40 vape
[00:04:49] <zeeshan> i dont see why youd wanna hundreds on a fancy one to do that
[00:04:53] <renesis> jymmm: 510/ego compatible means you can spend $15 and get an oil rig
[00:04:57] <zeeshan> shit i dont see why youd wanna do that for just smoking
[00:05:13] <renesis> but they have the little skirts to cover the ego cone threads, so they wont work with everything 510 threaded
[00:05:33] <Jymmm> renesis: Eh, I just have a clone MutX v2, I'm happy =)
[00:05:43] <renesis> like my mod battery doesnt have the groove, so you cant use ego compatible 510 on it
[00:05:44] <Rab> zeeshan, you should see what people pay for wristwatches.
[00:05:53] <zeeshan> rab very good point
[00:06:24] <Tom_itx> zeeshan, you should see it.. it's paying you
[00:06:28] <renesis> i paid like $35 for my mod and maybe $20 for the atomizer and had it over a year
[00:06:29] <zeeshan> i took this project cause it is something different, gave me a chance to practice my surfacing skills, play with a completely new material i've never machined before, and its good money
[00:06:47] <zeeshan> it's not something i would design and sell myself
[00:06:49] <renesis> wood composites are neat
[00:06:51] * Tom_itx alerts the DEA
[00:07:10] <zeeshan> i've also never machined true 3d geometry like this
[00:07:11] <renesis> they do stuff with gating to get a crappy swirly mix and can simulate wood grain pretty well
[00:07:26] <zeeshan> i think this will be a good experience
[00:07:30] <Tom_itx> zeeshan, be sure to eliminate all your air cuts
[00:07:33] <renesis> machining wood for mass production is fucked =(
[00:07:48] <Tom_itx> you will get alot of them when you generate the surface
[00:08:33] <renesis> oh
[00:08:37] <renesis> its not a juice port
[00:08:42] -!- Akex_ has quit [Quit: Connection closed for inactivity]
[00:08:44] <renesis> its for the electronics and display i guess
[00:09:05] <renesis> so is that supposed to be a lady in a saggy dress?
[00:09:22] <jdh> I thougth it was a headless bunny or praire dog maybe
[00:09:24] <Tom_itx> if it's polymer filled wood, why not mold it?
[00:09:34] <renesis> because prototype
[00:09:36] <Tom_itx> spend your time machining a good mold
[00:09:57] <zeeshan> i wish it was like that
[00:09:58] <zeeshan> heeh
[00:09:58] <Tom_itx> renesis, he's gearing up like it's not
[00:10:06] <zeeshan> Tom_itx: you take a very exotic piece of wood
[00:10:20] <zeeshan> and you vacuum bag and draw in acrylic resin for a couple hours
[00:10:25] <zeeshan> it fills up all the pores in the wood
[00:10:29] <zeeshan> but maintains the grain
[00:10:31] <renesis> well if they sell a few he can drop the time on injection molding the stuff so it actually looks like wood
[00:10:36] <zeeshan> make it look very pretty
[00:10:43] <Tom_itx> why not do that after it's machined?
[00:10:54] <zeeshan> because stablizing the wood helps with machining too
[00:11:05] <Tom_itx> and dulls the shit outta cutters
[00:11:11] <zeeshan> no
[00:11:16] <renesis> machining normal wood for mass production or assembly is a mess
[00:11:25] <renesis> it breathes, shit is alive
[00:11:48] <zeeshan> you get less chipout etc
[00:11:57] <zeeshan> i need it to be fairly strong
[00:12:01] <renesis> so composites you get some of the properties of wood, but its machinable, holds tolerances
[00:12:03] <zeeshan> so the thinner areas dont blow out
[00:12:09] <zeeshan> yep ren
[00:12:21] <Rab> Does the resin penetrate throughout the piece?
[00:12:24] <renesis> theres stuff made out of wood dust thats injection moldable
[00:12:25] <zeeshan> yes
[00:12:47] <Rab> renesis, thinking of bakelite?
[00:12:49] <renesis> rab: i think this is how they do the colored gunstocks
[00:12:57] <renesis> rab: yeah but not old
[00:13:17] <renesis> bakelite never looked like wood, or felt like it really
[00:13:33] <Rab> I'm so relieved this is stoner tech, I thought it was either a handle for a weapon or some kind of ridiculous grip shifter.
[00:13:37] <renesis> but mechanically, yeah like bakelite
[00:13:47] <zeeshan> rofl rab
[00:13:48] <zeeshan> haha
[00:13:51] <renesis> its not stoner tech
[00:14:01] <renesis> its nicotine junkie tech
[00:14:17] <renesis> you cant use standard cannabis oil atomizers with that
[00:14:23] <renesis> its not ego threaded
[00:14:46] <renesis> http://cdn1.bigcommerce.com/server4000/549f5/product_images/uploaded_images/ego-510-thread.jpg
[00:15:18] <renesis> the ego thread is for a cosmetic cone for first gen egos that use 510 attys
[00:15:47] <renesis> lots of atomizers have a skirt that covers the ego threads, doesnt screw on just cosmetic
[00:16:05] <zeeshan> https://www.youtube.com/watch?v=2A7b2v6Pe5Y
[00:16:08] <zeeshan> this is the only youtube video i can find
[00:16:09] <renesis> my ecig mod, and zee's project dont have the area for the skirt
[00:16:15] <zeeshan> and it literally looks like youre machining wax
[00:16:15] <zeeshan> haha
[00:16:20] -!- andypugh has quit [Quit: andypugh]
[00:16:20] <zeeshan> its so soft
[00:18:53] <renesis> its neat that it doesnt rip up into dust
[00:20:13] <Rab> zeeshan, are you machining out the internals before doing the exterior contours?
[00:21:35] <zeeshan> rab so this is my plan, hold on to your chair cause its elaborate :P
[00:21:54] <Rab> gripping chair firmly
[00:22:07] <zeeshan> http://i.imgur.com/NT9YDP8.png
[00:22:12] <zeeshan> so imagine this as a rectangular block of wood
[00:22:19] <zeeshan> i grip it in a 4 jaw on the very left
[00:22:27] <zeeshan> i machine the top surface
[00:22:50] <zeeshan> i index 90 degres, machine the side, index again machine the side index again machine the side. so 4 sides of the rect have been machined
[00:23:11] <Tom_itx> get a rotary with 5 axis software and machine it all at once
[00:23:17] <zeeshan> i repeat this for the next 9 pieces (im planning to do 10 at a time)
[00:23:33] <zeeshan> then i take the 4 jaw and mount it against the table
[00:23:36] <zeeshan> and machine:
[00:23:52] <zeeshan> http://i.imgur.com/BeUDddX.png
[00:24:01] <zeeshan> all these top surfaces, i drill and end mill all those circular holes you see
[00:24:13] <zeeshan> i forgot to mention something
[00:24:22] <zeeshan> the 4 sides that i did earlier
[00:24:31] <zeeshan> i go and pocket that triangular pocket
[00:24:33] <zeeshan> to fit that plate

[00:24:44] <Tom_itx> i figured that
[00:24:50] <zeeshan> now i need a negative fixture of my surface
[00:24:53] <zeeshan> cause i gotta machine the bottom
[00:25:18] <zeeshan> so i grip my work piece in the negative fixture , (fixture has flat surfaces on the exterior)
[00:25:34] <zeeshan> turn it upside down to machine the bottom pockets and big ass bore for the battery tube
[00:25:35] <Rab> zeeshan, tell that guy to fix his leaf/stem, it's gonna make people crazy.
[00:25:36] <Tom_itx> is the bottom perp to the hole?
[00:25:42] <Tom_itx> fixture the hole
[00:25:56] <zeeshan> fixture the top holes
[00:25:57] <zeeshan> that i machined?
[00:26:04] <Tom_itx> why not?
[00:26:15] <zeeshan> but how would i grip it firmly though?
[00:26:17] <zeeshan> using that one hole there
[00:26:27] <Rab> zeeshan, if you have trouble engraving the stainless, you could consider etching.
[00:26:35] <Tom_itx> set it down on that to locate it then use side clamps to hold it
[00:26:43] <zeeshan> rab ive played witrh engraving stainless before
[00:26:49] <zeeshan> im not at all worried about the stainless plates
[00:26:51] <zeeshan> jsut the wood
[00:26:52] <zeeshan> cause its complex
[00:26:57] <renesis> its drama
[00:27:32] <zeeshan> tom im not following you
[00:27:45] <zeeshan> http://i.imgur.com/EjigFt9.png
[00:27:54] <zeeshan> you can see in this pic the top circular features
[00:27:56] <Tom_itx> you could actually pin the larger hole then have a pin come up from the bottom of the fixture into the other hole to locate it firmly and clamp the sides
[00:28:11] <Tom_itx> fixture it in the vise
[00:28:20] <Tom_itx> so you can reach under and remove the pin

[00:28:45] <just_pink> hi
[00:28:46] <zeeshan> other hole
[00:28:48] <zeeshan> meaning the pocket
[00:28:56] <zeeshan> where the triangle plate goes?
[00:29:07] <Tom_itx> http://i.imgur.com/BeUDddX.png
[00:29:27] <Tom_itx> or locate it on the plate...
[00:29:37] <Tom_itx> so the pin on the bottom and the plate on the side
[00:29:39] <Rab> zeeshan, I see why you want a 4th axis.
[00:29:45] <Tom_itx> that would be best
[00:30:04] <zeeshan> hmm Tom_itx
[00:30:07] <zeeshan> i think that might work
[00:30:10] <Tom_itx> you would have it located in 2 axis then

[00:30:26] <zeeshan> lemme show you why else i was going to build a negative fixture
[00:30:26] <zeeshan> for this
[00:30:37] <zeeshan> its very hard to see compound holes and explain them
[00:30:42] <zeeshan> and shit model them, but ill try
[00:30:43] <zeeshan> http://i.imgur.com/w5aWhaE.png

[00:31:35] <zeeshan> you can see em better here
[00:31:45] <zeeshan> i was gonna machine angles into the fixture plate
[00:31:48] <zeeshan> so i can use it for that purpose

[00:31:53] <zeeshan> along with a drill guide
[00:32:00] <zeeshan> so i can go do that on the drill press while the other stuff is machining
[00:32:11] <Tom_itx> why does it have to be compound?
[00:32:31] <zeeshan> why as in -- why does the design have that?
[00:32:41] <Tom_itx> yeah
[00:32:45] <zeeshan> its needed, trust me :P
[00:33:01] <zeeshan> its the only way to be able to pass wires
[00:33:08] <zeeshan> without damaging anything else
[00:33:20] <zeeshan> or compromising on the 510 connection being secure
[00:33:33] <zeeshan> 510 is that thing the big silver cylinder screws into
[00:33:52] <zeeshan> http://i.imgur.com/EjigFt9.png
[00:34:00] <zeeshan> theres wires that come from the button
[00:34:02] <zeeshan> and the top of the battery tube
[00:34:09] <zeeshan> they need to go to the pcb module inside the triangle slot
[00:34:14] <zeeshan> theres no way to get those wires there
[00:34:24] <zeeshan> without doing a compound hole that brings them ousde the side of this handle
[00:34:26] <Tom_itx> did you see SpeedEvil's post about a battery vent?
[00:34:31] <zeeshan> yea
[00:34:37] <zeeshan> the vent for the battery is built into the bottom cap
[00:34:40] <zeeshan> its got vent holes
[00:35:39] <zeeshan> man if i can avoid a fixture for the drilling of holes
[00:35:43] <zeeshan> that'd be something
[00:36:16] <SpeedEvil> stubby bits can help
[00:36:16] <Tom_itx> i should have taken a pic of what my friend has to do to drill one tiny blind hole
[00:36:29] <zeeshan> SpeedEvil: not worried about wandering
[00:36:29] <SpeedEvil> what is the l/d ?
[00:36:37] <zeeshan> not enough to cause wandering
[00:36:39] <zeeshan> especially in wood!
[00:36:52] <SpeedEvil> zeeshan: especially at hole start
[00:36:52] <zeeshan> im drilling 2 compound holes that need to meet
[00:36:56] <zeeshan> if its out by 1 degree
[00:37:00] <zeeshan> it doesnt meet correctly
[00:37:17] <zeeshan> SpeedEvil: yea but you always start with a spot drill
[00:37:19] <zeeshan> or center drill
[00:37:37] <zeeshan> the drilling of holes is easy in my opinion
[00:37:39] <SpeedEvil> I suppose you've considered simply halving some nice wood with a fine kerf bandsaw, doing the ops on each half, and ...
[00:37:41] <zeeshan> its holding the part while doing so is hard :)
[00:37:55] <SpeedEvil> If lined up with the grain, it can be almost invisible
[00:38:09] <zeeshan> yes
[00:38:11] <zeeshan> but he doesnt want that
[00:38:13] <zeeshan> and i think it'll take longer
[00:38:24] <SpeedEvil> zeeshan: start out oversize, and simply glue it down to waste?
[00:38:41] <SpeedEvil> I don't understand your shapes, sorry
[00:38:48] <zeeshan> its okay
[00:38:50] <zeeshan> i dont understand them either
[00:39:03] <zeeshan> SpeedEvil: that'd work for making 10
[00:39:08] <zeeshan> but 40 -- might get a pain

[00:41:18] <zeeshan> working on that as we speak
[00:41:19] <Tom_itx> i see lots of potential for some of the walls to chip away on that design

[00:42:28] <zeeshan> between the cavity for the blue thing
[00:42:31] <zeeshan> and the battery cavity?
[00:42:45] <SpeedEvil> What's the wood
[00:42:47] <Tom_itx> that's one
[00:42:54] <Tom_itx> the top is another
[00:43:02] <zeeshan> that view is misleading
[00:43:09] <zeeshan> cause thats the thinnest section
[00:43:09] <Tom_itx> it may be minimal since it's round
[00:43:13] <zeeshan> exactly
[00:43:16] <Tom_itx> i know that
[00:43:19] <zeeshan> its round so i dont think itll be that bad
[00:43:19] <Tom_itx> but still
[00:43:29] <Tom_itx> hope for your sake...
[00:43:43] <zeeshan> well im gonna make one

[00:44:26] <zeeshan> and to be honest, i dont care!! lol
[00:44:49] <zeeshan> all i care about is how much i need to make from this

[01:07:25] <zeeshan> PetefromTn_: did you weld the flange?
[01:11:54] <PetefromTn_> well actually
[01:12:08] <PetefromTn_> I did not get the back purge setup in the mail today AGAIN
[01:12:22] <PetefromTn_> but they called me and said they needed it and to go ahead and weld it anyways
[01:12:29] <PetefromTn_> so I just did the best I could with it
[01:12:54] <PetefromTn_> it really fuzzed up on the inside and the outside did not look all that much better honestly
[01:13:14] <PetefromTn_> but I got it sealed up and welded and brought it over there
[01:14:24] <zeeshan> did you try cleaning the inside?
[01:14:34] <PetefromTn_> I tried EVERYTHING
[01:14:39] <PetefromTn_> I cleaned EVERYTHING
[01:14:55] <zeeshan> you know i hate ceramic coating so much
[01:15:04] <PetefromTn_> it just would not weld worth a shit no matter how much sanding/ scotchbriting/polishing I did to it
[01:15:07] <zeeshan> i coulda modified my old manifolds to make them work for my new setup
[01:15:09] <zeeshan> but i just threw em away
[01:15:22] <zeeshan> its such a critical piece i was like all new fresh metal!
[01:15:48] <PetefromTn_> he told me that they ALWAYS wrap their downtubes with Ti wrap and I watched them do it while I was there and install it in the car
[01:16:12] <PetefromTn_> I know the weld was not pretty or all that great really but they seemed to be okay with it.
[01:16:56] <zeeshan> haha
[01:16:58] <zeeshan> sweet
[01:17:01] <zeeshan> so you wont even really see the weld
[01:17:02] <zeeshan> :P
[01:17:09] <zeeshan> they dont have a tig welder there?
[01:17:13] <PetefromTn_> they were talking about building a big welding table for me when I start working there so I guess they are good with it. I definitely was NOT good with it but they kinda put me in a bad spot with the time frame and bad setup etc.
[01:17:29] -!- skunksleep has quit [Ping timeout: 260 seconds]
[01:18:02] <jdh> using their gear or yours?
[01:18:11] <PetefromTn_> I am really trying to get setup correctly and I have really been practicing a lot here
[01:18:11] <SpeedEvil> If it's a tube, can't you just tape some stuff over the end and flow gas into it?
[01:18:18] <SpeedEvil> Or am I misunderstanding
[01:18:26] <PetefromTn_> heh you can if you have a back purge reg LOL
[01:18:33] <SpeedEvil> Ah
[01:19:01] <PetefromTn_> I bought all that stuff and got it ordered but the people I ordered the Tee fitting from screwed me over with not getting it here even after a week
[01:19:23] <PetefromTn_> as of tonight they just emailed me and refunded my money
[01:19:47] <PetefromTn_> and they said if I do receive it to just keep it which is nice but it did not help me today that is for sure
[01:20:10] <PetefromTn_> to be quite honest with you today was HUGELY stressful with this thing...
[01:20:21] -!- skunksleep [skunksleep!~AndChat14@str-broadband-ccmts-ws-26.dsl.airstreamcomm.net] has joined #linuxcnc
[01:20:39] <PetefromTn_> I did not know whether to try to weld it without as they asked or to just turn it down and bring it back unwelded.
[01:21:22] <zeeshan> turning it down means they'll never give you a job again
[01:21:23] <PetefromTn_> they REALLY wanted it soon because the car is supposed to ship by Saturday so I thought better just do it. I may live to regret that decision
[01:21:29] <zeeshan> just weld and grind it clean
[01:21:31] <zeeshan> so you cant see the weld
[01:21:36] <zeeshan> that would i do that in this scenario
[01:21:39] <PetefromTn_> that is kinda what I did
[01:21:48] <PetefromTn_> reluctantly
[01:21:54] <zeeshan> its not gonna crack
[01:21:54] <PetefromTn_> I swear man that tube SUCKED
[01:21:55] <zeeshan> dont worry
[01:22:26] <PetefromTn_> it had so much contamination in it even on the top side I could not believe it...
[01:22:49] <PetefromTn_> I tried every trick I know to make it flow out good but you can see the shit in the welds around the edges no matter what you do...
[01:23:20] <PetefromTn_> The Stainless flange was great and that part is fine but where it joined to that frackin' tube was a disaster I swear...
[01:23:50] <PetefromTn_> They said it was fine and I told them I would not blame them if they cut the damn thing off and started over LOL...
[01:24:29] <PetefromTn_> he told me that they WANTED me to make a whole new downpipe for the car but the owner kinda cheaped out on them so they had no choice
[01:26:13] <PetefromTn_> I don't doubt it will not break it is solid enough and I got good penetration but it sure was not the prettiest weld
[01:27:11] <zeeshan> anyoine that knows anything about welding
[01:27:19] <zeeshan> knows welding used old shit exhaus ttubing
[01:27:23] <zeeshan> especially with ceramic coating on it
[01:27:30] <zeeshan> is going to weld like ass
[01:27:31] <zeeshan> :P
[01:27:54] <PetefromTn_> I don't know I never had to do it before but I sure do now.
[01:27:57] <zeeshan> so if they know th is, they will be good to work with!
[01:28:15] <PetefromTn_> what really sucks is I really wanted to be able to impress them at least a little bit with the first job...
[01:28:29] <zeeshan> i know the feeling
[01:28:34] <zeeshan> cause you're starting a fresh relationship
[01:28:40] <PetefromTn_> what's that they say about first impressions...?
[01:28:54] <zeeshan> if i can be honest..
[01:29:01] <zeeshan> i think for a job like this being on time is more important
[01:29:04] <zeeshan> than the quality of weld
[01:29:08] <zeeshan> as long as it holds
[01:29:08] <zeeshan> its ok
[01:29:19] <zeeshan> but being your first weld for them, i understand
[01:29:29] <zeeshan> if i have a new customer for welding and it goes like ass
[01:29:44] <zeeshan> i always show them a sample piece of a weld -- what it could look like when the conditions are correct
[01:29:57] <zeeshan> if youre going to give me a 1/4" plate and get me to weld 1/16" aluminum to it
[01:30:02] <zeeshan> it's gonna look like ass
[01:30:08] <zeeshan> i can guarantee you that before i start!
[01:30:30] <zeeshan> (for a butt weld, not lap)
[01:31:56] <PetefromTn_> it's funny I DID bring a piece of that stainless tube I was practicing on just to show them that I don't completely suck LOL
[01:32:30] <zeeshan> good :)
[01:32:44] -!- tannewt has quit [Quit: My Mac has gone to sleep. ZZZzzz…]
[01:32:55] <PetefromTn_> I have been playing with this stainless a lot here
[01:33:08] <PetefromTn_> and I am getting a bit more consistent with my technique...
[01:33:16] <PetefromTn_> but I still have problems with the greying
[01:33:26] <PetefromTn_> I tried to go a lot hotter and a lot cooler
[01:33:36] <PetefromTn_> I tried varying my movements
[01:33:54] <PetefromTn_> of course I still don't have the proper back purge setup here
[01:34:32] <PetefromTn_> but I would love to be able to get that nice coloration a bit more and some of that bluish tint in there.
[01:34:35] <PetefromTn_> any suggestions?
[01:34:50] <zeeshan> the blue tint is going to happen with back purge
[01:35:01] <zeeshan> but the rainbow colors
[01:35:04] <PetefromTn_> OK nice
[01:35:05] <zeeshan> you can do without
[01:35:25] <PetefromTn_> I am talking more that coppery coloration on the beads themselves
[01:35:46] <PetefromTn_> sometimes I get it really good and then the next time not
[01:35:52] <PetefromTn_> kinda frustrating
[01:35:54] <zeeshan> yea thats back purge
[01:35:57] <zeeshan> that means like 0!!!!!!!!!!1
[01:36:02] <zeeshan> contamination
[01:36:20] <PetefromTn_> I clean the crap out of the pieces beforehand
[01:36:35] <PetefromTn_> I have been REALLY REALLY trying to get everything clean and tight before I strike up
[01:36:47] <zeeshan> if its the color youre trying to achieve
[01:36:51] <zeeshan> itll be effortless with backpurge
[01:36:56] <zeeshan> (on the bead itself)
[01:37:06] <PetefromTn_> Wow nice I hope so...
[01:37:17] <zeeshan> you can get away with overheating the weld
[01:37:18] <PetefromTn_> that would really put my welds in a lot better light
[01:37:42] <zeeshan> http://i1123.photobucket.com/albums/l550/customdesign/IMG_0481_zps13912c58.jpg
[01:37:42] <PetefromTn_> I have been thinking about this stuff a lot lately...
[01:37:58] <zeeshan> ^ this guy is overheating the weld
[01:38:06] <zeeshan> but it doesnt show
[01:38:06] <zeeshan> hehe
[01:38:09] <PetefromTn_> even if it does not work out with these guys for whatever reason I absolutely want to get this down and be able to do it very well..
[01:38:32] <PetefromTn_> wow why is that so concave
[01:38:40] <zeeshan> surface prep
[01:38:42] <zeeshan> huge v
[01:38:55] <PetefromTn_> I put a good vee into mine too
[01:39:01] <zeeshan> not big enough :P
[01:39:02] <PetefromTn_> maybe I need to back off on that
[01:39:12] <PetefromTn_> on mine?
[01:39:24] <zeeshan> no i mean if you want his type of weld
[01:39:31] <zeeshan> you'd need to go even bgiger than you are right now
[01:39:39] <zeeshan> but you definitely need back purge
[01:39:48] <PetefromTn_> that does not look like a good thing to me tho right?
[01:39:58] <zeeshan> nahh
[01:40:04] <zeeshan> if you wanted to be a certified welder
[01:40:05] <PetefromTn_> I mean the spacing looks real good
[01:40:07] <zeeshan> you gotta do it like that
[01:40:13] <zeeshan> cause this guarantees 100% penetration
[01:40:28] <PetefromTn_> then they lay another bead over top right?
[01:40:31] <zeeshan> yes
[01:40:36] <PetefromTn_> ok
[01:40:49] <PetefromTn_> do you do this on the schedule 40 exhaust stuff?
[01:40:56] <zeeshan> no!
[01:41:05] <zeeshan> cause i dont need 100% penetration or strength
[01:41:06] <zeeshan> 80% is fine
[01:41:12] <zeeshan> its not worth the money in gas for me
[01:41:14] <zeeshan> or the customer
[01:41:18] <PetefromTn_> I wonder if toxicfab does..
[01:41:22] <zeeshan> definitely does
[01:42:36] <zeeshan> https://s-media-cache-ak0.pinimg.com/736x/07/51/0c/07510c7a5ddc7d87ab76348e3aeb49f6.jpg
[01:42:40] <zeeshan> you can see the surface prep here
[01:43:00] <zeeshan> a grinder for V is okay
[01:43:04] <PetefromTn_> looks like a billet flange
[01:43:12] <jdh> I found/fixed a ~100 SCFH helium leak thr other day
[01:43:14] <zeeshan> but the problem is your v will be in consistent
[01:43:21] <zeeshan> and itll frigging throw your puddle off slightly
[01:43:26] <zeeshan> and make the weld look jagged
[01:43:43] <zeeshan> yea PetefromTn_ it is a billet flange
[01:43:46] <zeeshan> but im saying the prep for welding
[01:43:51] <PetefromTn_> another reason that belt grinder will come in handy
[01:44:07] <zeeshan> jdh
[01:44:11] <zeeshan> give me helium
[01:44:14] <zeeshan> i cant afford it!
[01:44:31] <PetefromTn_> you can use helium to superheat your welds
[01:44:35] <zeeshan> yes
[01:44:38] <zeeshan> for aluminum it comes handly
[01:44:42] <zeeshan> when my machine is too small
[01:44:43] <zeeshan> :(
[01:44:44] <jdh> it will be quite a cost savings
[01:45:30] <zeeshan> PetefromTn_:
[01:45:31] <zeeshan> YES
[01:45:37] <zeeshan> i finally found a pic of toxic fab
[01:45:41] <zeeshan> not being a robot
[01:45:43] <zeeshan> http://i43.tinypic.com/2mguvcz.jpg
[01:45:48] <zeeshan> look inthe very middle
[01:45:53] <zeeshan> he even overheated his weld!
[01:45:53] <zeeshan> :D

[01:46:37] <PetefromTn_> but the guys definitely NOT a robot
[01:46:43] <zeeshan> im trying to find a damn picture
[01:46:46] <zeeshan> where he's screwed up
[01:46:52] <PetefromTn_> he's kinda a tatted up skinny guy LOL
[01:46:56] <zeeshan> YES
[01:46:57] <zeeshan> YES YES
[01:47:02] <zeeshan> his aluminum welding
[01:47:19] <PetefromTn_> freaking glorious right

[01:51:15] <PetefromTn_> how much post flow do you set on stainless like this?
[01:51:28] <zeeshan> 12 sec
[01:51:43] <PetefromTn_> Woah okay I am at like five LOL
[01:51:47] <zeeshan> haha
[01:51:49] <zeeshan> thats too little
[01:52:30] <PetefromTn_> okay will add more
[01:52:47] <zeeshan> the rule of thumb is
[01:52:50] <PetefromTn_> do you think I should make two passes on this Sch40 stuff
[01:52:53] <zeeshan> 1sec psot flow for every 10 amps
[01:52:57] <zeeshan> no
[01:53:20] <zeeshan> you know the rule of thumb for thickness ?
[01:53:38] <zeeshan> 1A per 1 thou?
[01:54:06] <PetefromTn_> yeah
[01:55:14] <PetefromTn_> it's a shame you are so far away we could probably do some cool stuff together.....but then again we might just kill each other too Hehehe
[01:55:27] <zeeshan> haha
[01:56:28] <zeeshan> one day id like to build a weld robot
[01:56:35] <zeeshan> thatd be sweeeeeeeeet
[01:56:43] <PetefromTn_> that pic you posted it is surprising how tight the heat zone is against the side of that weld
[01:56:56] <jdh> I'm putting in an automatic welder with 2 robots
[01:57:09] <zeeshan> jdh have you implemented a tig bot?
[01:57:12] <jdh> but, the robots don't weld...just material handling
[01:57:17] <zeeshan> youre at lincoln electric right?
[01:57:29] <jdh> not a bot, but I have two automated tig welders
[01:57:42] <jdh> heh...not hardly.
[01:57:49] <PetefromTn_> I thought you were kidding heh
[01:57:59] <zeeshan> haha
[01:58:09] <jdh> I weld tubing
[01:58:11] <zeeshan> nah PetefromTn_ -- id like to be able to do production runs for personal product
[01:58:17] <zeeshan> like car stuff
[01:58:24] <zeeshan> i dunno if i showed you this pic..
[01:58:25] <zeeshan> sec
[01:58:34] <jdh> or rather, I dont' weld shit... I have machines that weld 24x7
[01:58:40] <zeeshan> lol

[02:06:09] <zeeshan> i already asked him for throw away things
[02:06:10] <zeeshan> :)
[02:06:11] <flyback> hehehehe
[02:06:13] <PetefromTn_> what did you use to polish them after welding?

[02:08:16] * flyback still hasn't had that privledge
[02:08:19] <renesis> and flyback gets banned from #electronics like every other week
[02:08:20] <flyback> probably never will
[02:08:34] <renesis> just go to a hooker
[02:08:38] <zeeshan> PetefromTn_: im not gonna lie at all
[02:08:39] <renesis> also you troll moon

[02:08:43] <flyback> i rather die a virgin than pass on the brakage anyways
[02:08:44] <PetefromTn_> hell I'd like to have a welding rotary fixture
[02:08:57] <flyback> I am going to go out like ripley at the end of alien 3

[02:09:48] <PetefromTn_> right now I am kinda stunned at what they are getting for completed Tig welded parts LOL
[02:09:48] <zeeshan> like i really enjoy welding
[02:09:51] <zeeshan> like the other day you made me go do some
[02:09:59] <zeeshan> but when youre doing like 100s of the same weld

[02:10:37] <PetefromTn_> like just screwing around practicing with the stainless fittings I was enjoying that
[02:10:39] <zeeshan> like the stuff they purchase?
[02:10:56] <flyback> man I am glad the industry got the same idea I got on my own

[02:11:18] <PetefromTn_> they gotta be beautiful tho
[02:11:18] <zeeshan> but at the end of they day , thats all they're doing right
[02:11:33] <zeeshan> usually they outsource their flanges
[02:11:36] <zeeshan> for machining etc
[02:11:37] <flyback> ford can't fap fast enough to their 3d printers for plastic and 3d printers for sand molds for metal parts
[02:11:42] <zeeshan> they specifically pipe fit
[02:11:42] <PetefromTn_> shit if I could get my skills up enough to get a grand for one I would be pretty fuckin' happy LOL
[02:11:55] <t12> i always find whenever i'm welding
[02:12:02] <t12> something about the setup is so un-ideal
[02:12:11] <t12> that it's going to come out like shit no matter what
[02:12:15] <t12> but its also never anything critical
[02:12:18] <PetefromTn_> t12 I know right...no matter what you do
[02:12:20] <zeeshan> t12 you gotta go watch a pro do it
[02:12:24] <zeeshan> you're doing it wrong
[02:12:25] <flyback> t12 better flux?
[02:12:34] <t12> i find its primarily positioning
[02:12:34] <zeeshan> !
[02:12:41] <t12> like i was welding up some steel tube frame stuff
[02:12:44] <zeeshan> dude i thought i was ok at welding
[02:12:45] <flyback> or mabye your welding rod is too impuire
[02:12:46] <t12> in a cramped room
[02:12:49] <zeeshan> when i saw the welder at school
[02:12:53] <zeeshan> and their welding table
[02:12:54] <t12> next to the floor
[02:12:55] <t12> upside down
[02:12:59] <zeeshan> i realized how STUPID my table is
[02:13:00] <t12> constrained
[02:13:07] -!- [cube] has quit [Ping timeout: 246 seconds]
[02:13:14] <flyback> t12 no matter what
[02:13:17] <flyback> you have my respect
[02:13:18] <PetefromTn_> what kinda table did they have
[02:13:21] <flyback> weldiong is a art
[02:13:27] <t12> my dad was a boilermaker
[02:13:31] <zeeshan> http://www.edwardsdesignandfab.com/images/300_Weldsale_Welding_table.JPG
[02:13:32] <t12> lots and lots and lots of welding
[02:13:32] <flyback> cool
[02:13:33] <zeeshan> this one
[02:13:35] <zeeshan> dude
[02:13:39] <flyback> yeah and they have to be dead on
[02:13:43] <zeeshan> theres this clamp that goes through those square holes
[02:13:48] <t12> theres one weld thats partner
[02:13:48] <PetefromTn_> oh I have seen those.
[02:13:49] <flyback> or they have to say sorry to several dozen families
[02:13:52] <zeeshan> iyou can hold the part in any possible position
[02:13:52] <PetefromTn_> spensive!!
[02:13:53] <zeeshan> its crazy
[02:13:58] <t12> where one person welds around 180 degreess of a tube
[02:13:59] <zeeshan> infact the guy at school wont weld anything
[02:14:02] <zeeshan> unless its bolted down solid
[02:14:06] <t12> and someone else picks the arc up and finishes the other side
[02:14:07] <zeeshan> cause he says itll warp otherwise
[02:14:25] <zeeshan> orry
[02:14:26] <zeeshan> found the pic
[02:14:31] <flyback> there were a lot of midgit welders and mechanics in WW I and II
[02:14:34] <zeeshan> correct one:
[02:14:38] <flyback> must have made them proud
[02:14:38] <zeeshan> http://bluco.com/wp-content/uploads/2012/09/welding-table-for-equipment-rack.jpg
[02:14:42] <flyback> :D
[02:14:43] <zeeshan> it looks like that, but the holes are square
[02:14:44] <zeeshan> not round
[02:14:48] <flyback> once some of those planes were built
[02:14:52] <flyback> you couldn't get back in side
[02:14:53] <flyback> they could
[02:14:53] <zeeshan> and clamps look very similar to that
[02:15:01] <PetefromTn_> that is probably a $5k table
[02:15:10] <zeeshan> yep
[02:15:15] <zeeshan> and some asshole grinded to put an angle grinder through it
[02:15:15] <zeeshan> LOL
[02:15:21] <PetefromTn_> yeah that's not gonna happen over here LOL
[02:15:22] <zeeshan> im glad that it isn't my table
[02:15:28] <flyback> PetefromTn_, did you ever watch the diacovery show
[02:15:42] <flyback> where they would take the tail unit from scrapped jets and make this like 10k tablet
[02:15:45] <flyback> err table
[02:16:09] <PetefromTn_> I have seen lots of crazy stuff like that....making couches out of cars etc..
[02:16:10] <t12> lol all this idealist welding
[02:16:11] <flyback> I mean they were nice it looked like it was crafted not just cut up and sold
[02:16:23] <flyback> sadly a few weeks into the show, one of the 3 guys dropped dead
[02:16:27] <jdh> http://i.imgur.com/I03E0sa.jpg
[02:16:35] <zeeshan> nice!
[02:16:39] <zeeshan> robot?
[02:16:43] <PetefromTn_> yeah man
[02:16:45] <t12> finally got welding machine back in the house though
[02:16:47] <flyback> holy mother of canuck jdh
[02:16:51] <flyback> was that a weld?
[02:16:55] <jdh> nope, tennessee rednecks
[02:16:56] <t12> and actually bought all sizes of everything
[02:17:04] <jdh> Titanium
[02:17:10] <t12> bike frame?
[02:17:16] <jdh> yeah
[02:17:20] <flyback> what is that if it wasn't a weld
[02:17:22] <PetefromTn_> I gotta get my skills built up like that somehow...
[02:17:24] <zeeshan> i dont wanna put down that weld
[02:17:29] <zeeshan> but fillet welds are the easiest to do
[02:17:33] <flyback> i was going to say whoeever did it polished it up so well you could easily miss it
[02:17:35] <zeeshan> but welds are stupid hard
[02:17:49] <zeeshan> show me a butt weld!
[02:17:59] <jdh> everything is jigged, tacked, finished, polished
[02:18:05] <flyback> I get that ever time my IBS acts up zeeshan
[02:18:15] <PetefromTn_> I find that anywhere you have a flange or something to guide from I do well.. this tubing you really don't have anything but yourself to guide from
[02:18:48] <PetefromTn_> and the part is continually radiused so you have to constantly adjust your torch angle as you go.
[02:18:49] <jdh> my last Ti bike I sold had really nice welds (Seven in boston)
[02:19:21] <flyback> I heard titanium is a rigteous c*** to weld
[02:19:22] <PetefromTn_> so keeping everything tight, following the radius, and maintaining a straight line gets hard
[02:19:37] <zeeshan> PetefromTn_: exactly man
[02:19:41] <zeeshan> butt welds are hard!!!
[02:19:45] <flyback> it's more canucked than zeeshan
[02:20:14] <zeeshan> PetefromTn_:
http://www.mig-welding.co.uk/restoration-floor/tig-weld.jpg
[02:20:19] <PetefromTn_> which makes me so amazed when you see toxicfab and guys like that lay down INSANELY consistent ones..
[02:20:22] <zeeshan> just remember, you're better than this guy
[02:20:22] <zeeshan> :-)
[02:20:28] <zeeshan> everytime i do a crap one
[02:20:32] <zeeshan> i look at crappier ones!
[02:20:41] <PetefromTn_> LOL you didn't see that shit I did today HAHAHAHAHA
[02:20:53] <zeeshan> lol
[02:21:02] <flyback> I gave someone hell a few months ago because they had some few hundred $$$ welder
[02:21:03] <PetefromTn_> I almost wanted to apologize for it
[02:21:06] <flyback> and the fan had died
[02:21:11] <flyback> and they were just going to run it till it burned
[02:21:34] <zeeshan> PetefromTn_: you know color isn't a good thing in a weld right?
[02:21:36] <PetefromTn_> like I said it was not pretty but it sure as hell should hold...
[02:21:47] <zeeshan> its only inthe car world where people love the color
[02:21:48] <PetefromTn_> it is in stainless right
[02:21:52] <zeeshan> noo
[02:22:03] <zeeshan> if you look at some work for santiary stuff like for food related
[02:22:08] <zeeshan> or food manufacturing
[02:22:14] <jdh> or nuclear fuel
[02:22:17] <zeeshan> all the color has to be removed, and the tubes polished
[02:22:29] <PetefromTn_> yeah but it's there after the weld no?
[02:22:34] <jdh> or welded with no color in a <5ppm weld box
[02:22:43] <zeeshan> cause the areqa where the color is, thats where your pipe will corrode
[02:22:53] <zeeshan> yes after the weld
[02:23:06] <zeeshan> im just saying the stuff you see by toxic fab for example
[02:23:14] <zeeshan> you'd never see that in a real application of stainless
[02:23:28] <zeeshan> jdh: why nuclear
[02:23:31] <zeeshan> didnt knoe that
[02:24:12] <jdh> unfriendly environment
[02:24:14] <zeeshan> http://www.bssa.org.uk/topics.php?article=2
[02:24:17] <PetefromTn_> http://s1123.photobucket.com/user/customdesign/media/12-28-12_2112.jpg.html ??
[02:24:21] <zeeshan> explains it well
[02:24:34] <zeeshan> yes thats a great weld
[02:24:39] <zeeshan> but the colors gotta go for sanitary :P
[02:24:53] <flyback> going to do the weekly shave, nice chatting
[02:25:07] <PetefromTn_> I am seriously hoping the back purge will help me get some of that coloration in there. the guys love that shit LOL
[02:25:20] <PetefromTn_> weekly?
[02:25:27] <PetefromTn_> hell I gotta do it every day LOL
[02:25:41] <zeeshan> PetefromTn_: t hats the thing
[02:25:44] <zeeshan> its become so mainstream now
[02:25:49] <zeeshan> everyone thinks its a good thing
[02:25:51] <flyback> once a week when it reaches the 'I can feel it moving" stage
[02:25:52] <zeeshan> cause it looks pretty
[02:26:01] <PetefromTn_> sure does
[02:26:05] <zeeshan> but in reality, you're runing the high temp performance of the stainless
[02:26:13] <zeeshan> and corrosion resistance
[02:26:20] <zeeshan> (which is why people use em for exhaust manifolds to begin with!)
[02:26:25] <jdh> Pete: you can make a Tee with some long nipples and a plain NPT tee
[02:26:47] <flyback> that's what she said
[02:26:49] <PetefromTn_> yeah but I can't screw the damn thing into the argon bottle
[02:26:59] <jdh> sure you can.
[02:27:04] <zeeshan> how jdh
[02:27:06] <zeeshan> i wanna know too!
[02:27:11] <jdh> take the 580's off, put in the nipples
[02:27:13] <zeeshan> cause i struggled before i got the T to find a custom solution
[02:27:14] <PetefromTn_> show me don't tell me LOL
[02:27:21] <jdh> mount them on teh Tee... put one of the 580's on teh T
[02:27:54] <zeeshan> shit youre right
[02:28:01] <PetefromTn_> doesn't this have to be a high pressure setup tho?
[02:28:04] <zeeshan> the cg580 is on a PIPE nipple
[02:28:16] <jdh> I use HP brass or SS
[02:28:26] <PetefromTn_> got a pic?
[02:28:32] <jdh> I wouldn't use home depot stuff, but parker is fine
[02:28:37] <PetefromTn_> I can't envision what you mean
[02:28:38] <zeeshan> at t he end of the day
[02:28:40] <zeeshan> its cheaper to get t he T
[02:28:41] <zeeshan> :P
[02:28:50] <zeeshan> pete he's saying this:
[02:28:51] <zeeshan> http://www.esseti.co.nz/uploads/products/116/images_large/XG-ARLFG.jpg
[02:28:56] <zeeshan> unscrew the pipe nipple
[02:28:58] <PetefromTn_> yeah if the assholes you bought it from actually ship it
[02:29:05] <zeeshan> grab a T to screw that nipple into
[02:29:13] <zeeshan> then get 2 more nipples to go to your regulators
[02:29:30] <PetefromTn_> my reg does not look anything like that
[02:29:35] <flyback> I have seen those solid shileds too
[02:29:37] <flyback> using sand etc
[02:29:58] <flyback> I think it was a robot machine
[02:30:07] <flyback> laying down shield, weld, remove shield
[02:30:12] <PetefromTn_> http://www.ebay.com/itm/140514184508?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[02:30:21] <PetefromTn_> that is what mine look like
[02:30:33] <jdh> the 580 nipple is 1/4" npt on the reg
[02:30:35] <PetefromTn_> one is older and is round glass but same thing basically
[02:31:37] <PetefromTn_> so you are saying unscrew the whole nipple/tube from the side of the reg and use standard NPT pipe fittings/tees right
[02:31:50] <jdh> I put Parker ST quick connects on the 580's. THen I have T's, hoses, gauges, etc. with matching quick connects so I can mix and match gases
[02:32:05] <jdh> Pete:right, then put one of the 580's you took off in teh T also
[02:32:08] <PetefromTn_> PICS!!!
[02:34:29] <jdh> no good pics
[02:34:31] <jdh> http://www.artichoke.org/jjpg/fill.jpg
[02:34:37] <jdh> the reg on the bottom right
[02:35:07] <PetefromTn_> looks like origami LOL
[02:35:48] <jdh> that was an o2 reg, it had a 540, but same idea
[02:36:24] <zeeshan> lol jdh
[02:36:25] <zeeshan> youre right
[02:36:35] <zeeshan> mine has a 1/4" npt pipe going into -- just checked

[02:37:28] <zeeshan> pete is this yours?
[02:37:43] <PetefromTn_> something like that
[02:37:50] <zeeshan> i like that style
[02:37:56] <zeeshan> with the ball that floats
[02:38:07] <PetefromTn_> yeah both of mine are like that
[02:38:17] <zeeshan> my one is like that
[02:38:19] <zeeshan> thje other is a gauge
[02:38:25] <zeeshan> ball is easier to read :P
[02:38:45] <zeeshan> jdh nice grow up
[02:39:14] <jdh> ?
[02:39:17] <zeeshan> what is that for?
[02:39:21] <zeeshan> filling smaller tanks
[02:39:25] <zeeshan> from a larger tank
[02:39:27] <zeeshan> aka transfer station?

[02:40:41] <zeeshan> do you mix your own gases for diving?

[02:41:47] <zeeshan> how do you ensure you got the right mixturte

[02:42:28] <jdh> I have oxygen and helium analyzers
[02:42:28] <zeeshan> thats SERIOUS business
[02:42:37] <zeeshan> awesome!!
[02:45:30] <zeeshan> jdh do you use a regular car o2 sensor
[02:45:37] <zeeshan> for analyzing the oxygen concentration?
[02:45:46] <jdh> medical o2 sensors
[02:45:52] <zeeshan> is there a difference?
[02:45:59] <zeeshan> the the reason i ask is, one project i have on the list
[02:46:08] <zeeshan> is building a gas analyzer for the garage
[02:46:18] <jdh> what gas?
[02:46:35] <zeeshan> o2 , co2, co, hc, argon
[02:46:43] <zeeshan> and i know a bit weird
[02:46:44] <zeeshan> but propane
[02:46:45] <jdh> dunno what car sensors do. These put out ~10mV in air
[02:46:57] <jdh> 60mV in 100%o2
[02:47:15] <zeeshan> linear?
[02:47:22] <jdh> yeah
[02:48:29] <jdh> I generally put in old sensors that I rotate out of my rebreahter
[02:49:12] <jdh> sensors are $60-100 and are 1% at best. Not sure what you are looking for in an analyzer
[02:49:22] <zeeshan> well i was looking a complete system
[02:49:27] <zeeshan> and its way beyond my bduget lol
[02:49:31] <zeeshan> like 5k
[02:49:43] <zeeshan> if i could build a generic module wher ei can add sensors as i go
[02:49:45] <zeeshan> that'd work the best
[02:50:34] <jdh> 5k is cheap if it is anywhere near accurate
[02:51:21] <jdh> the lcd on the top has an rPi that does o2 and pressure
[02:52:06] <zeeshan> are you using an amplifier
[02:52:13] <zeeshan> to get the o2 voltage to a sane level
[02:52:25] <zeeshan> rpi has no adc from what i remember
[02:52:35] <jdh> no, I ditched the amps after rev1
[02:52:53] <jdh> I use 18bit i2c ADC's
[02:53:29] <zeeshan> cool
[02:53:34] <jdh> 2.048v vRef so it has way more precision than Ineed
[02:54:35] <jdh> http://tinyurl.com/nh8vs33 number on right is mV
[02:55:01] <zeeshan> wait
[02:55:06] <zeeshan> so youre feeding directly into the adc
[02:55:10] <zeeshan> without amplification
[02:56:06] <jdh> maybe. don't actually remember. Some of the ADC's I got had a programmable gain stage.
[02:56:39] <zeeshan> the ones i came across didnt only 128 gain
[02:56:40] <zeeshan> maxx
[02:56:48] <jdh> these are max 8
[02:56:49] <zeeshan> i remember looking for one for my strain gauge
[02:57:12] <jdh> with 18bits and low vRef, you don't need an amp
[02:59:31] * zeeshan is noob with electronics
[02:59:39] <jdh> 18bits on this adc maxes out at a few hz

[06:00:36] <pingufan> Good morning. I am milling plastic enclosures. In one project I had to mill letters entirely through the material, then close them with transparent laminate for backlighting. The problem are loose parts (i.e. the inner of an "o". So I am looking for a font (ttf preferred, as Cut2D can process them) with short sticks remaining between inner and outer material.
[06:00:49] <pingufan> Hope I could explain good enough what I need.
[06:01:09] <zeeshan> what cam are you using?
[06:01:14] <zeeshan> a lot of them have the fonts built in
[06:01:16] <zeeshan> for this sort
[06:01:35] <Wolf_> why not bond the laminate to the back first?
[06:02:17] <pingufan> I use Cut2D. It has some fonts, but noone has this bridges. I can use them for engraving, but not for milling through.
[06:02:31] <archivist> google for a stencil font
[06:04:28] <pingufan> Wolf_: How shall this work? I have to entirely mill through material, and I have to mill from rear side. So I cannot put a tape on front side and keep it intact while entirely get through the plastic everywhere.
[06:06:37] <pingufan> archivist: Thanks for this hint. I didn't know what to search for. :)
[06:06:41] <Wolf_> oh, you are laminatign the front over the letters…
[06:06:53] <zeeshan> man i just got done with cam programming this handle
[06:06:54] <zeeshan> http://i.imgur.com/NrGq6El.jpg
[06:06:59] <zeeshan> http://i.imgur.com/V8JR0y4.jpg
[06:07:18] <zeeshan> its crazy how easily the tool paths were generated
[06:07:21] <zeeshan> took about 2 hours
[06:07:28] <zeeshan> mostly cause im a noob :P
[06:07:37] <zeeshan> i was making a silly mistake inthe type of 3d tool path
[06:07:43] <zeeshan> (and optimizing)
[06:07:57] <zeeshan> ~2-3 hour machining time
[06:08:13] <Wolf_> that looks (un)fun
[06:08:28] <archivist> way too slow
[06:09:20] <zeeshan> archivist: actual cam time says 1hr 20 min
[06:09:27] <zeeshan> but setup etc
[06:09:30] <zeeshan> i predict 3 hours ~
[06:09:34] <pingufan> Wolf_: The plastic part is 3mm thick and black material, therefore I cannot backlight it. So I have to entirely mill through it in first step. Then I put a adhesive tape on the front side and pour in clear and transparent resin/laminate from rear side. Works well, but it was no fun to draw every letter manually.
[06:09:34] <zeeshan> unless i get a 4th axis
[06:09:57] <zeeshan> i got the 1/4" ball nose programmed at 20 ipm feed, 10ipm plunge
[06:10:03] <archivist> 4th axis and a fast spindle
[06:10:16] <zeeshan> archivist: im hooking up a router to my machine
[06:10:19] <zeeshan> router spindle
[06:10:33] <zeeshan> but i feel like at 80ipm, i might not be able to evac chips fast enough
[06:11:32] <zeeshan> can optimize after ive cut the first one
[06:11:39] * zeeshan needs to decide on 4th axis
[06:12:01] <pingufan> Does somebody know a good G-Code emulator for SuSE LINUX (rpm)? Actually I want to load the generated G-Code file and then simulate the milling process on screen. Currently I run linuxCNC in virtualbox (because it runs on Ubuntu and I use SuSE), but this is a little heavy.
[06:12:35] <archivist> look at openscam
[06:12:59] <pingufan> This crazy guys only made a .deb package. :/
[06:13:15] <archivist> use the source
[06:14:36] <pingufan> I stopped doing that years ago. It always ended in endless dependency issues. Therefore I prefer pre-compiled binaries in rpm.
[06:15:01] <archivist> you cannot be too fussy when stuff is free
[06:15:10] <zeeshan> lol
[06:15:34] <zeeshan> pingufan: imagine if you had to run windows
[06:15:36] <zeeshan> and mach3
[06:15:45] <pingufan> I know. But on other hand it can be a real odyssee sometimes
[06:16:02] <zeeshan> since it is bothering you so much
[06:16:10] <zeeshan> why dont you make a rpm for us
[06:16:17] <pingufan> I am happy to run Windows in a Window (Now it is in right place)
[06:16:23] <archivist> am I being too fussy I paid £10 for one of these (different badge)

[06:16:32] <archivist> and its faulty!
[06:16:41] <zeeshan> archivist: how dare you buy china crap
[06:16:57] <archivist> 3 year guarantee!
[06:17:00] <zeeshan> hehe
[06:17:08] <zeeshan> was it doa?
[06:17:12] <Wolf_> I would bitch
[06:17:12] <archivist> .1 degree resolution!
[06:17:13] <zeeshan> or just stopped working after a little while
[06:17:31] <archivist> random angle but systemic errors
[06:17:56] <archivist> move it to 90 and it states 90 exactly
[06:18:37] <archivist> take it to bits and explore or return it for replacement :)
[06:19:19] <zeeshan> hehe
[06:19:24] <archivist> the brake is a crude cover then you can see the "encoder"
[06:19:31] <fenn> how do you measure small angular errors in your measuring device?
[06:19:44] <zeeshan> fenn: against a square
[06:19:48] <archivist> with an angle dekkor
[06:19:58] <Wolf_> could be worse, I have 20 of these that don’t work
http://www.extech.com/instruments/product.asp?catid=59&prodid=758
[06:20:12] <Rab> archivist, what's the encoder technology?
[06:20:22] <zeeshan> actually you could easily check for angle errors
[06:20:26] <zeeshan> by mounting a laser to it
[06:20:34] <zeeshan> and projecting it at a far away distance
[06:20:56] <pingufan> For sure the best way!
[06:21:08] <archivist> looks like two pcbs with a pattern (not undone that part (locktite)
[06:21:28] <Wolf_> 20… typo 2 of them
[06:21:30] -!- tlab_ [tlab_!~tlab@209.59.38.48] has joined #linuxcnc
[06:22:06] <Rab> To align the laser, you'd need instruments so precise you could just use them to measure the thing directly.
[06:22:09] <archivist> but so cheap for 3600 resolution
[06:22:42] <Rab> archivist, maybe capacitive like digi calipers.
[06:23:04] <fenn> the laser method would be a relative measurement
[06:23:20] <Rab> fenn, oh, of course
[06:23:23] <fenn> measure at 0 degrees, measure at some other angle, measure the distance between the spots with tape measure
[06:23:27] <archivist> Rab, very likely but the errors sort of point at software error in the chip
[06:23:37] <zeeshan> fenn: it would work suprsingly well :P
[06:24:17] -!- tlab__ has quit [Ping timeout: 246 seconds]
[06:24:28] <zeeshan> man 4th axis might take too much work to implement right now
[06:24:34] <zeeshan> i could buy a rotary table and index it 90 degrees
[06:24:37] <fenn> for extra creidt use beamsplitter to cancel out the spots
[06:24:39] <zeeshan> that'd help!
[06:25:12] <fenn> you don't need a rotary table to rotate 90 degrees
[06:25:21] -!- Komzpa has quit [Read error: Connection reset by peer]
[06:25:23] <zeeshan> it'd be quicker
[06:25:25] <zeeshan> than a stop and a vise
[06:25:34] <zeeshan> and ill maintain the axis of rotation
[06:25:41] <fenn> hm ok
[06:25:51] <zeeshan> so i dont have to redial the part center every time
[06:25:54] <zeeshan> you know what i mean?
[06:25:59] <fenn> yeah
[06:26:17] <fenn> i was thinking you put it in a precision toolmaker's vise
[06:26:27] <fenn> so whichever way you clamp it, it's a known distance
[06:26:34] <fenn> good enough for woodwork anyway
[06:26:37] <zeeshan> haha
[06:26:46] <pingufan> Thanks for your help with fonts. Have to leave. :)

[06:28:31] <zeeshan> too big for what i need though
[06:28:35] <zeeshan> im looking for a 6" or 8"
[06:29:13] <fenn> you want A/B axis
[06:29:22] <zeeshan> thatd be awesome :P
[06:29:36] <zeeshan> if i can stall this guy for 2 weeks
[06:29:40] <zeeshan> i can prolly build something
[06:30:46] <fenn> there's the vise i was talking about
http://www.kijiji.ca/v-tool-other/hamilton/toolmaker-tools-tool-die/1096411922
[06:30:55] <zeeshan> yes i got one of those
[06:31:20] <zeeshan> my problem with building a 4th axis
[06:31:29] <zeeshan> is just like everyone elses issue
[06:31:30] <zeeshan> backlash
[06:31:37] <zeeshan> either i need a harmonic drive
[06:31:45] <zeeshan> or i run some complex belt arrangement
[06:31:55] <zeeshan> along with a brake
[06:32:23] <archivist> or it is wood and dont care
[06:32:23] <fenn> you can preload two gears or two half worm wheels against each other
[06:32:31] <zeeshan> archivist: if im building something
[06:32:33] <zeeshan> itll be for metal
[06:32:36] <zeeshan> not this crappy wood!! :P
[06:32:42] <zeeshan> fenn: those wear out
[06:32:48] <zeeshan> belts do too
[06:32:50] <zeeshan> but not at the same rate
[06:33:02] <archivist> I use unidirectional gcode to ignore backlash
[06:33:13] <fenn> ball bearing cycloid gear
[06:33:27] <zeeshan> haramonic drive is pretty sweet
[06:33:32] <zeeshan> cause you can get a 100:1 gear ratio in it
[06:33:34] <fenn> i think it's dumb
[06:33:35] <zeeshan> and its so small and compact
[06:33:39] <zeeshan> why
[06:33:52] <zeeshan> almost all top end manufacturers use a haramonic drive
[06:33:57] <zeeshan> so it's gotta be good!
[06:34:10] <fenn> you can do the same thing with a cycloid gear and it doesn't cost a bazillion dollars
[06:34:16] <fenn> also it's stronger
[06:34:55] <zeeshan> how can you do that with a cycloid gear?
[06:35:19] <zeeshan> they use them in oil pumps
[06:35:22] <zeeshan> but those rotate in 1 direction
[06:35:27] <fenn> sorry i meant cycloidal drive
https://en.wikipedia.org/wiki/Cycloidal_drive
[06:36:36] <zeeshan> Cycloidal drives, and similar ball reducers or rotating ball gears, have no gearing. Instead, they transmit torque through preloaded balls, rollers, or pins from one moving plate to another. These devices provide zero backlash and low noise, but need their preloads retightened in service to stay backlash-free. They operate smoothly, withstand high shock loads and vibration, and have efficiencies u
[06:37:59] <zeeshan> Flat harmonic drives are available for limited space applications. Combined with pancake motor and integrated encoder, such drives operate in robotic and automation applications, mainly for integral horsepower drives. Despite these advantages, backlash increases with wear.

[07:04:55] <zeeshan> so take a worse case scenario -- 500lb of force that causes torsion at a distance of 4" away. (8" diameter workpiece) -- need 2000lb-in (167lb-ft, 32000oz-in) direct drive servo!

[07:05:42] <archivist> total bollocks
[07:06:47] <zeeshan> that means a typical 1200oz-in servo, that means i need a 26:1 gear ratio
[07:06:48] <zeeshan> jeez
[07:07:04] <zeeshan> archivist: wow thats dirt cheap

[07:08:25] <zeeshan> thats a cute little design
[07:09:03] <zeeshan> i could do a compound pulley setup
[07:09:11] <zeeshan> to get a 30:1 gear ratio
[07:09:17] <zeeshan> i mean pulley ratio
[07:10:07] <archivist> zeeshan, but that one I pointed at is not harmonic despite the title!
[07:10:13] <zeeshan> haha
[07:10:35] <archivist> baby trunnion looks....baby
[07:10:53] <zeeshan> prolly good for small jobs
[07:10:56] <zeeshan> like on wood and aluminum
[07:11:04] <zeeshan> but if you really wanna take advantage of 4th axis
[07:11:20] <zeeshan> like theres so many parts ive done in the past
[07:11:25] <zeeshan> i coulda done so much easier on the 4th axis
[07:11:30] <zeeshan> much less setup time
[07:12:10] <zeeshan> archivist: im trying to think of a situation where a bidirection a-axis is important
[07:12:13] <zeeshan> vs unidirectional
[07:13:16] <zeeshan> you also prolly need to be careful on the cut direction
[07:13:30] <zeeshan> so you're never forcing the table in the slack direction
[07:14:16] <archivist> I am fussy about the division accuracy hence the rotaries I use
[07:14:35] <zeeshan> for clock work?
[07:14:48] <archivist> any gear cutting
[07:15:06] <zeeshan> lol
[07:15:11] <zeeshan> i was gonna design something in solidworks
[07:15:19] <zeeshan> but i found exactly what iwas thinking
[07:15:33] <zeeshan> http://www.cnczone.com/forums/attachment.php?attachmentid=141748&stc=1&thumb=1&d=1389526639
[07:16:02] <archivist> running the belt through the endplate on the baby trunnion is silly
[07:16:04] <zeeshan> so your first ratio is 1 to 6 and then again 1 to 6
[07:16:08] <zeeshan> so you get 36:1
[07:16:53] <fenn> why is it silly?
[07:17:04] <zeeshan> fenn:
[07:17:07] <zeeshan> chips i would think
[07:17:08] <fenn> the end plate needs more meat for sure
[07:17:21] <archivist> it reduces stiffness of the endplate
[07:17:33] <zeeshan> which one are you talking about
[07:17:34] <zeeshan> the one i posted?
[07:17:44] <archivist> mount the motor on the trunnion
[07:17:49] <fenn> http://i.ebayimg.com/00/s/NzAwWDcwMA==/z/DVUAAOSw6BtVStJd/$_57.JPG
[07:18:33] <fenn> archivist: so the base part would be wider but the whole thing is the same length, gothca
[07:18:59] <archivist> my motor on my A causes me problems in clearance so I know why they went that way
[07:19:16] <zeeshan> its a more compact design
[07:19:22] <zeeshan> but iagree wqith you
[07:19:26] <zeeshan> theres barely any meat in that plate
[07:19:27] <zeeshan> lol
[07:19:42] <archivist> too busy making it cheap
[07:19:43] <zeeshan> but it's an easy fix
[07:19:50] <zeeshan> you dont even need a thicker plate
[07:19:54] <zeeshan> cause it's not gonna do much
[07:19:58] <fenn> it's just as compact with the motor on the trunnion
[07:20:00] <archivist> and then over charging for it
[07:20:06] <zeeshan> i'd build a bug box around the stepper motor on the left
[07:20:10] <zeeshan> that would really reinforce it
[07:20:21] <zeeshan> actually itake that back
[07:20:27] <zeeshan> no it wont :P

[07:20:47] <zeeshan> i think im almost positive
[07:20:54] <zeeshan> im gonna go the compound pulley route
[07:20:55] <zeeshan> its cheap
[07:20:56] <zeeshan> easy to do
[07:21:03] <zeeshan> i can build it prolly for under 300 bux

[07:21:25] <zeeshan> you guys have me thinking though

[07:22:06] <zeeshan> if i buy the factory rotary table
[07:22:09] <zeeshan> that is your C axis
[07:22:26] <zeeshan> and then i mount my 4th axis (A axis)
[07:22:38] <zeeshan> technically i can get a really compact setup

[07:25:47] <fenn> right
[07:26:07] <zeeshan> okay im motivated to build a 4th axis
[07:26:11] <fenn> if it were just a rotary that mounted the same way (no 90 degree angle plate) the you could use it as B axis
[07:26:24] <zeeshan> thats true
[07:26:31] <zeeshan> fenn: that's exactly how the newer versionsof my machine are

[07:29:52] <zeeshan> archivist: im so glad you convinced me to get the mikron
[07:30:01] <zeeshan> i was so clueless about it back then
[07:30:09] <zeeshan> i look on kijiji for other milling machines for fun
[07:30:22] <zeeshan> and they are all flimsy pos bridgeports
[07:30:27] <zeeshan> that have been converted

[07:33:09] <zeeshan> they're built tough
[07:33:17] <zeeshan> haha
[07:33:24] <zeeshan> why are myfords so famous in uk?
[07:33:38] <fenn> you can carry them down the basement stairs
[07:33:38] <zeeshan> is it something to do with that was the most common lathe in schools back in the day
[07:33:41] <zeeshan> so people can relate to them?
[07:33:50] <archivist> it is the same as VHS v Beta
[07:33:51] <zeeshan> fenn: but thats not usually a good thin when it comes to machining metal!

[07:34:15] <zeeshan> fenn: even if i didnt have a garage
[07:34:20] <zeeshan> i'd haul it down my basement

[14:51:28] <SpeedEvil> though - the pantorouter does simplify things enormously in many ways

[14:52:15] <malcom2073> True
[14:52:35] <SpeedEvil> Software is never going to crash, axes require no power or screws, ...
[14:52:55] <SpeedEvil> And it's almost certainly going to be working in 50 years - if you just replace the router perhaps
[14:53:05] <malcom2073> I'm trying to think out if there is some other use for a horizontal cnc router

[14:57:57] <ssi> was worth it

[14:58:15] <PetefromTn_> it worked pretty good tho and it is kinda cool to be able to push a 7klb machine with your hands LOL

[14:58:40] <PetefromTn_> I rented mine for like $45.00

[14:59:29] <PetefromTn_> that is the hardest part....aside from just getting them underneath the damn machine LOL
[14:59:43] <_methods> rent those railroad jacks
[14:59:58] <_methods> 1 or 2 railroad jacks to get skates under and go for it
[15:00:02] <PetefromTn_> I used a porta power unit from HF..still have it here

[15:16:16] <SEL> hi, i wonder how to wire inductive sensors in series as they have 3 wire ?
[15:16:50] <skunkworks> you need and or or gates
[15:17:24] <pcw_home> you can wire two of the same type in parallel
[15:18:15] -!- marrrk has quit [Quit: marrrk]
[15:18:49] <SEL> hmm wouldn;t this confuse the controller as on the same pin there will be one sensor open and one closed when at home or limit position
[15:19:04] <pcw_home> (that is they both have to be PNP or NPN or they will fight and one or both will lose )
[15:21:13] <SEL> sensors are NC but if I wire them in parallel on the same pin this cannot work as one sensor fires 0V while the other is at 5V on the same pin

[15:27:17] <pcw_home> Not really, normally 3 wire Prox's are NPN or PNP type
[15:28:20] <pcw_home> NPN types have a switch to ground and PNP types have a switch to V+
[15:29:05] <pcw_home> the switch is either on or open so they can be paralleled if they are of the same type
[15:31:21] <pcw_home> (there are push-pull types you cannot parallel but they are uncommon)

[15:34:29] -!- zeitue has quit [Remote host closed the connection]
[15:35:55] -!- quiqua has quit [Quit: quiqua]
[15:36:22] <SEL> the pins on the board are at 5V and the sensors are NC so current is flowing when both are closed, but current flows through the pin if one only is closed, so this achieves nothing
[15:37:40] <pcw_home> That may be true depending on whether the are NO or NC, but common 3 wire proxes _can_ be paralleled
[15:38:42] <pcw_home> whether the combined switch logic you get is useful depends on what you are doing (and whether you have NO or NC switches)
[15:38:43] <SEL> if they where NO I would have to invert the pin in the hal file with a -not
[15:39:11] <pcw_home> depends if they are NPN or PNP
[15:39:35] <pcw_home> PNP pull high when on, NPN pull low
[15:43:14] -!- JohnyK has quit [Remote host closed the connection]
[15:43:54] <pcw_home> If these are limit switches best is probably NC and 2 separate inputs
[15:44:37] -!- sumpfralle [sumpfralle!~lars@megumi.opennet-initiative.de] has joined #linuxcnc
[15:45:12] <pcw_home> (PNP NC has a slight edge for limits since a open or shorted to ground error will show up as on-limit)
[15:46:38] amnesic is now known as amnesic_away
[15:46:47] <SEL> exactly, but the board has 3 pins one for each home switch
[15:50:51] <pcw_home> and how many switches total?
[15:54:17] <SEL> well 3 home switches and 3 limit
[15:55:23] <SEL> but probably if I set the axis travel in the INI file I don't need limit switches?
[15:56:24] <skunkworks> could your machine destroy itself if it ran into the hard limits?
[15:58:23] <SEL> so the solution is to wire the sensors in series so that when one switch is open, no current flows
[15:58:38] -!- sumpfralle has quit [Ping timeout: 246 seconds]
[15:59:01] <pcw_home> that works for mechanical switches...
[15:59:33] <archivist> you cant wire them in series if 3 wire (power gnd collector(switch))
[15:59:35] <PetefromTn_> Well my damn Tee fitting finally arrived here.. Only about a week later LOL
[16:00:41] <pcw_home> or just use 3 combined home/limit switches
[16:03:21] -!- skunkworks has quit [Read error: Connection reset by peer]
[16:04:19] <SEL> they exist ?
[16:04:59] <pcw_home> Linuxcnc can be setup to use the same switch for both
[16:06:18] <SEL> that i know, but it is a wiring problem, i looked at 4 wire sensors but those are just NC + NO
[16:09:30] <pcw_home> Not sure there's any useful way to logically combine separate home/limit switches anyway
[16:15:11] <pcw_home> I guess X+ limit and X- Home could be ORed for example and untangled in HAL but what a mess
[16:16:02] <JT-Shop> for limit switches all tied together then any one breaks the loop the machine stops but doesn't know which axis violated the limit
[16:16:16] -!- SpeedEvil has quit [Quit: No Ping reply in 180 seconds.]
[16:16:47] <JT-Shop> for homing you have to make sure you only home one axis at a time
[16:16:56] -!- SpeedEvil [SpeedEvil!~quassel@tor/regular/SpeedEvil] has joined #linuxcnc
[16:17:41] <SEL> yes i have set the sequence numbers
[16:18:14] <zeeshan> nice pete
[16:18:19] <pcw_home> so you could get by with 2 inputs (limit and home)
[16:19:01] <pcw_home> but if you used 3 wire proxes they would need to be NO so they can be paralleled
[16:20:29] <zeeshan> if its a mill
[16:20:35] <zeeshan> it's nice to be able to home Y and X together
[16:20:43] <zeeshan> it does save a bit of time :P
[16:20:52] <pcw_home> on the other hand if you are going to the trouble to use inductive proxes why not just get more inputs?
[16:21:38] <JT-Shop> Stepconf has a choice of "All limits + homes"
[16:21:39] <SEL> i have buy another board and not a cheap one
[16:22:21] <JT-Shop> limits are ignored when homing a combined limit and home but proxes add another level
[16:23:12] <SEL> that one was 40$
[16:24:34] <SEL> home + max limit
[16:32:24] <SEL> oh NO proxes with the pin inverted, this could work
[16:34:23] <archivist> are proxies accurate as home switches, do they have a repeatability spec? ,some mechanicals are cheap and good
[16:35:16] <SEL> I have them on my router

[16:43:22] -!- shogunx_ has quit [Remote host closed the connection]
[16:43:26] <archivist> some microswitches have a 1 thou spec
[16:43:46] <pcw_home> thats initial trip point I think, repeatability is probably much better
[16:44:05] <archivist> no spec for repeatability though
[16:44:42] <pcw_home> yeah and it probably changes with voltage, temperature etc
[16:45:09] <zeeshan> it can't be that bad
[16:45:18] <zeeshan> cause i get really good repeatability with the 1 prox switch i have on my machine
[16:45:31] <zeeshan> like it has to be in a couple of tenths
[16:45:53] <pcw_home> prox or prox+ index?
[16:45:55] <archivist> also has 10% hysteresis
[16:46:09] <zeeshan> its just a 3 wire prox switch
[16:46:11] <archivist> someone should measure one :)

[16:49:58] <JT-Shop> anyone seen my tape measure, I've lost it again
[16:50:16] <cradek> check your back pocket and to the right of wherever you're standing

[16:59:52] <zeeshan> do it faster!
[17:01:06] <PetefromTn_> I have some USA made versions of that tool... it works okay in softer materials but I would not try it in hard materials I don't think it will take the side loads too well...
[17:01:10] <archivist> damned cheap, like that angle thing I got, how good/bad will it be
[17:01:12] <Rab> Maybe, but no speed regulation. So if the tool bogs down, which is pretty easy, you might get a crappy finish.
[17:01:51] <Rab> IOW might not want to plan everything around that "54000 RPM" figure.
[17:01:53] <archivist> cheap enough to try

[17:06:05] <PetefromTn_> yeah you can't quick change tools but I typically only used it for wood or engraving things if I needed quick change I made due with the 6k RPM main spindle

[17:21:22] <zeeshan> you guys think double sided tape would work to machine a 0.0625 thick plate of stainless
[17:21:36] <jdh> yes
[17:21:38] <JT-Shop> depends on the tape
[17:21:45] <jdh> 3m
[17:21:47] <JT-Shop> some will not hold and some hold well
[17:21:55] <zeeshan> im also using mist coolant
[17:21:59] <JT-Shop> there is different grades of tape
[17:22:06] <jdh> I can get you a 3m part num in a few
[17:22:11] <zeeshan> thank u
[17:24:41] <Rab> zeeshan, vacuum table!
[17:24:47] <zeeshan> i wish!!
[17:25:15] <zeeshan> i have 3 approaches to make this..
[17:25:33] <Rab> Carpet tape is pretty damn strong. 3M VHB is supposedly extremely strong, but I haven't tried it. I think you'd want the version without foam backing.
[17:29:27] <PetefromTn_> maybe you can machine a shallow pocket to hold the parts while you are engraving them...
[17:29:35] <zeeshan> http://i.imgur.com/BLLcALX.jpg
[17:29:43] <zeeshan> i have actually 4 options
[17:29:55] <zeeshan> so im thinking of #1 sending these for water jet cutting
[17:30:01] <PetefromTn_> methods I have used these before and they work fine... I don't have any here but we had them in the Pro woodshop I used to work in for awhile..
[17:30:28] <zeeshan> #2 , if that is too expensive, then I will stack 10 of these at a time
[17:30:32] <zeeshan> (each one is .0625 thick)
[17:30:58] <zeeshan> and machine the outside
[17:31:02] <PetefromTn_> laser cut?
[17:31:14] <PetefromTn_> then you won't have to machine the outside
[17:31:27] <zeeshan> it'd be nice to keep the money for waterjet cutting
[17:31:34] <zeeshan> like i think if i stack 10 of em, it might be worth doing
[17:31:45] <zeeshan> cause itll prolly take 10 - 15 min per stack
[17:31:59] <_methods> would sure make changing router bits easier
[17:32:11] <zeeshan> PetefromTn_: i really like your idea about the shallow pocket
[17:32:16] <zeeshan> very smart!
[17:32:26] <PetefromTn_> the first one I posted actually is a real quick change setup
[17:32:48] <jdh> 3m VHB 5952
[17:32:48] <PetefromTn_> I have used the vacuum a couple times now to hold down parts
[17:32:56] <PetefromTn_> it has its uses and limitations
[17:33:20] <PetefromTn_> but depending on what you are making and the surface area of the bottom of the part it works okay
[17:33:20] <zeeshan> that looks very much like 3m molding tape
[17:33:56] <PetefromTn_> that stuff is crazy strong but you will be changing it out each time..
[17:34:39] <zeeshan> i think im just gonna stack em 10 at a time
[17:34:53] <zeeshan> do one outside contour, then flip the toe clamps and do other side
[17:34:56] <zeeshan> it shouldnt take too long

[17:35:21] <zeeshan> but they were much thinner
[17:35:26] <zeeshan> like 0.025 thick
[17:35:28] <PetefromTn_> well something always seems to move on me
[17:35:31] <PetefromTn_> I know you did
[17:35:35] <alex80> hi
[17:36:14] <zeeshan> im gonna expand on your idea about the pocket
[17:36:20] <zeeshan> i think drill 2 holes dowel it up
[17:36:31] <PetefromTn_> a shop with a CNC laser would make real short work of that part both for cutting it out as well as laser engraving them..
[17:36:31] <zeeshan> use that for engraving
[17:36:43] <zeeshan> he wants depth
[17:36:46] <zeeshan> not etch
[17:37:04] <PetefromTn_> ok
[17:37:05] <zeeshan> it's so frigging hard quoting for stuff
[17:37:11] <zeeshan> annoys me
[17:37:18] <PetefromTn_> I know
[17:37:22] <PetefromTn_> it is difficult
[17:37:27] <zeeshan> i seem to screw myself always
[17:37:46] <PetefromTn_> but anymore I just do whatever I think will allow me to make whatever I need for it.....and don't worry about it.
[17:38:36] <zeeshan> pete with the shallow pocket you were talking about
[17:38:46] <zeeshan> i dont think id even need to clamp the part down
[17:38:49] <zeeshan> for engraving..
[17:39:05] <jdh> bowing
[17:39:11] <zeeshan> its tiny though
[17:39:14] <PetefromTn_> its possible
[17:39:19] <jdh> twss
[17:39:43] <zeeshan> its like 1.75"x.875"
[17:39:59] <Rab> Unless the pocket is press-fit, I think the plate will chatter in the pocket.
[17:40:13] <PetefromTn_> I think you need to hold it down somehow
[17:40:51] <SpeedEvil> Trained beaver.
[17:40:54] <PetefromTn_> some sacrificial jaws with that shallow pocket in the vise would hold it nice if you clamp gently

[17:41:21] <PetefromTn_> how many of these do you have to make?
[17:41:24] <Rab> See if the stainless stock is magnetic.
[17:41:26] <zeeshan> 40
[17:41:26] <PetefromTn_> why?
[17:41:32] <zeeshan> rab its not
[17:41:34] <zeeshan> its 304
[17:41:37] <PetefromTn_> I make LONG sacrificial jaws for stuff like that...
[17:41:37] <zeeshan> lovely :)
[17:41:38] <Rab> ahh
[17:41:48] <PetefromTn_> could probably do at least five at a time
[17:42:24] <zeeshan> okay thats not a bad idea
[17:42:29] <zeeshan> but igotta make sure they're all the same :)
[17:42:36] <zeeshan> (they need to be)
[17:42:46] <PetefromTn_> why wouldn't they be?
[17:42:50] <zeeshan> its funny how the 4 ideas i had in my mind
[17:42:55] <zeeshan> have been transformed to something completely else
[17:42:58] <zeeshan> thanks to you :P
[17:43:03] <PetefromTn_> sorry heh
[17:43:22] <PetefromTn_> just trying to help give alternatives
[17:43:29] <zeeshan> yea i really like the vise jaw idea
[17:43:31] <PetefromTn_> there is always more than one way to make something
[17:43:59] <zeeshan> well with a vise jaw
[17:44:05] <zeeshan> first of all its much less material to machine
[17:44:11] <zeeshan> cause youre machining only a small shadow
[17:44:22] <zeeshan> i dont have to waste a whole aluminum plate on it
[17:44:29] <zeeshan> like i was imagining -- with a bunch of dowel holes all over it
[17:44:45] <zeeshan> and 5 at a time is reasonable because engraving time is about 8 min per piece
[17:44:48] <zeeshan> ccause im limited to 3000 rpm
[17:45:23] <PetefromTn_> I have a BUNCH of sacrificial jaw fixtures out there for various things..
[17:46:08] <PetefromTn_> they allow a lot of flexibility and great clamping power when you need it.. or gentle when you don't.. you can even put a torque wrench on the vise screw to ensure they are all clamped the same way
[17:47:11] <zeeshan> ooo
[17:47:14] <zeeshan> thats a GOOD idea
[17:47:24] <zeeshan> cause when using aluminum soft jaws, i noticed the part shifts a bit
[17:47:28] <zeeshan> because it digs into the aluminum
[17:47:34] <zeeshan> a torque wrench will minimize tat
[17:47:36] <zeeshan> *that
[17:48:04] <PetefromTn_> not sure if it would work for that part but I have also seen people use a dovetail bit to cut the pocket so the walls are tapered helping to pull the part down into the pocket...
[17:49:18] <PetefromTn_> it is really easy to OVER torque a good vise it seems like I always crank down hard on it.... the reality is a lot of time it is not necessary to do that unless your vise is a piece of shit like my Chinese CNC vise LOL
[17:49:57] <PetefromTn_> with the KURT I don't remember the clamping force ratings but it is pretty incredible....
[17:50:19] <zeeshan> a lot :P
[17:50:52] <PetefromTn_> http://www.kurtworkholding.com/manual-vise-opening-p-1205-l-en.html
[17:51:11] <PetefromTn_> it's actually quite easy to distort even a thick part if you are not careful..
[17:51:46] <PetefromTn_> a lot of the parts we machined in that production facility I first worked in they used torque wrenches because people were killing parts by clamping down too hard on them...
[17:52:16] <PetefromTn_> part deflects in the vise, program is run, part is released and springs back... way out of specs now...
[17:53:10] <archivist> interesting thing I found at a scrap yard is a clamping force measuring tool
[17:54:31] <zeeshan> at kurt vise castings made in china?
[17:54:32] <zeeshan> or usa

[19:40:12] <PetefromTn_> ick
[19:40:16] <Rab> You could align the filament laterally, and use vapor polishing, but the thing's still basically a porous bacteria swim park...ugh.

[21:50:18] <LatheBuilder2> Cut my first part!
[21:50:39] <LatheBuilder2> Tricky bit now is getting the spindle scaling correct.
[21:51:54] <LatheBuilder2> Digging through the various threads and docs, I seem to be missing something. Using a mesa 5i25/7i77, vfd spindle (0-10v).
[21:53:50] -!- chillly has quit [Quit: Ex-Chat]
[21:54:07] <LatheBuilder2> adjusted the scalemax, minlim, and maxlim. With a setting of 10 and below they function as expected, above 10 and it is like the output saturates.
[21:54:47] <LatheBuilder2> Setting should be: scalemax = 3000, minlim = 0, maxlim = 3000.
[21:55:29] -!- kb8wmc has quit [Ping timeout: 244 seconds]
[21:55:31] <LatheBuilder2> wondering if there is another parameter functioning as a clamp?
[21:58:41] <LatheBuilder2> if I understand correctly, PCW's 7i77 handles scaling directly. gain not required to be set
[22:00:32] <PCW> what is you maximum spindle RPM (at 10V)?
[22:00:38] <LatheBuilder2> 3k
[22:01:35] <PCW> so scalemax should be 3000, minlimit 0 maxlimit 3000 (for 0 to +10 only)
[22:02:19] <LatheBuilder2> direction pin is separate
[22:03:15] <LatheBuilder2> (checking params on mill, back in a moment)
[22:09:09] <LatheBuilder2> ok, found my test log. the parameters I set are: hm2_5i25.0.7i77.0.1.analgout5-[maxlim/minlim/scalemax]. if set to 3000/0/3000, all spindle speed ranges set from 0.00001 to 3000 yield spindle on but barely moving.
[22:11:24] <LatheBuilder2> tested changing parameters one by one and the thing is see is this: adjusting scalemax from 1 thru 10 inclusive yields expected speeds
[22:12:23] <LatheBuilder2> ie I command m3 s5, I get pretty close to half spindle speed. m3 s10 pretty close to full speed
[22:12:42] -!- nofxx [nofxx!~nofxx@unaffiliated/nofxx] has joined #linuxcnc
[22:13:43] <LatheBuilder2> if is set scalemax over 10, regardless of maxlimit and minlimit, when the spindle is turned on at any speed commanded it turns on, but only at minimum speed

[22:40:06] <XXCoder> ahh. nice :)
[22:42:31] <LatheBuilder2> spindle does not run at any speed other than just-barely-on with these settings. If I change scalemax to 10, minlimit to 0 and maxlimit to 10 it runs full speed at a commanded speed of "10" and behaves as expected, except for the scaling.
[22:43:21] <LatheBuilder2> feels like there is another parameter I am missing? An override?
[22:44:14] <XXCoder> unfortunately I dont know enough
[22:44:18] <zeeshan> is there benefit in using the hm2 pins to scale

[22:44:30] <zeeshan> for spindle speed? (cause im using the component)

[22:46:03] <LatheBuilder2> the odd thing is for scalemax of 10 and under, it functions linearly. above 10 and zero difference

[22:47:38] <LatheBuilder2> it is latest stable branch build of lcnc, but ubuntu 10.xx LTS

[23:02:05] <XXCoder> "located in usa" nice and clear place.. :P
[23:02:25] <XXCoder> it has more details later but jeez lol
[23:02:25] <LatheBuilder2> i have some debugging to do, now not working even with scalemax 10/minlim 0/maxlim 10. I've changed something else without realizing it
[23:04:05] <PCW> sounds like you are not setting the parameters you think you are
[23:05:21] -!- tocka has quit [Client Quit]
[23:06:03] <PCW> beware that to have parameters in the INI file work depends entirely on the hal file doing the expected thing with them
[23:08:02] <zeeshan> what i love about that mori seiki you posted
[23:08:06] <zeeshan> the overarm for the control panel
[23:08:16] <zeeshan> is prolly more sturdy than a china router!
[23:08:16] <zeeshan> :P

[23:11:22] <zeeshan> wow
[23:11:25] <zeeshan> that is a clean machine
[23:11:54] <CaptHindsight> For parts or not working ... yet
[23:12:07] <zeeshan> glass scales
[23:12:08] <CaptHindsight> perfect for conversion
[23:12:11] <zeeshan> :-)
[23:12:26] <zeeshan> too bad its too far away
[23:12:27] <XXCoder> broken Z
[23:12:54] <XXCoder> and according to em, only issue.
[23:13:18] <XXCoder> NJ million miles away from me
[23:13:26] <XXCoder> and not really interested in lathes lol
[23:13:33] <XXCoder> its nice but I like routers more

[23:15:27] <XXCoder> this is what I use at work more or less
[23:15:41] <XXCoder> bit different model but yeah
[23:16:05] <zeeshan> cool

[23:16:20] <XXCoder> zeeshan: it works but it does suck in many respects
[23:16:29] <zeeshan> like hoiw
[23:16:33] <XXCoder> and one I linked to is more recent, 90s one. mines 1988
[23:16:39] <XXCoder> "mine" but yea lol
[23:17:09] <XXCoder> zeeshan: for example no chip removal, it drains in back so hard to keep drains clear
[23:17:18] <zeeshan> doh
[23:17:20] <XXCoder> weird interface to send and get files
[23:17:35] <XXCoder> yet in few respects better than 90s hurco
[23:18:10] <zeeshan> http://www.adgrind.com/Studer/S33/Studer_S33_Grey.jpg
[23:18:12] <XXCoder> for one, you can modify value. hurco you have to use cvalculator then input new value
[23:18:18] <XXCoder> that was dumb of hurco
[23:18:21] <zeeshan> this was one of the machines i had to fix at a job a while back
[23:18:26] <zeeshan> its a sexy as hell machine
[23:18:29] <XXCoder> any computer should be able to calculate
[23:18:45] <XXCoder> grinder cnc interesting
[23:19:47] <zeeshan> but the rteason i brought that up
[23:19:53] <zeeshan> you'd think grinding just makes little dinky dusty
[23:20:00] <zeeshan> after 3 days
[23:20:12] <zeeshan> we'd have 90lb of dinky dust particles
[23:20:12] <zeeshan> lol
[23:20:15] <XXCoder> you die from cancer? lol
[23:20:19] <zeeshan> and it had no chip conveyor
[23:20:21] <zeeshan> so it just collected
[23:20:35] <zeeshan> the machine operator had to go inside the machine and scoop it out with a shovel
[23:20:39] <zeeshan> !
[23:20:41] <XXCoder> fun
[23:21:06] <XXCoder> couple of machines at my machine its like that and they DO have chip removers
[23:21:14] <zeeshan> lol
[23:21:15] <XXCoder> because sheer amount of chips
[23:21:29] <XXCoder> barrels worth of chips a day
[23:21:38] <XXCoder> one part a day
[23:22:27] <XXCoder> hmm
[23:22:33] <XXCoder> interesting design
