[01:24:30] <Tom_itx> zeeshan did you get your collet situation worked out?
[01:24:42] <zeeshan> nope
[01:24:44] <zeeshan> im sad about it

[01:29:03] <zeeshan> http://i.imgur.com/vhL9KE8.png
[01:29:06] <zeeshan> i reallyt dont see the problem
[01:30:56] <PetefromTn_> what IS the problem?
[01:31:04] <zeeshan> it doesnt seat right
[01:31:13] <zeeshan> ive already checked my adjustment
[01:31:17] <zeeshan> i talked to ott jakobs
[01:31:20] <zeeshan> they gave me a spec.
[01:31:22] <zeeshan> its within spec
[01:31:26] <zeeshan> so something else is faked
[01:31:50] <zeeshan> the machine is supposed to originally use a din2080 tool holder
[01:32:00] <zeeshan> you can see that the pull studs are the same.
[01:32:23] <zeeshan> and in all 3 tool holders
[01:32:25] <PetefromTn_> well not really according to that picture
[01:32:28] <zeeshan> the taper begins at the exact same point
[01:32:43] <PetefromTn_> does it?
[01:32:47] -!- deanputney has quit []
[01:32:48] <zeeshan> yea it does
[01:32:48] <Tom_itx> how does it fit the taper with no pullstud installed?
[01:32:49] <PetefromTn_> did you make that picture
[01:32:59] <zeeshan> PetefromTn_: yea i drew it from standard drawings
[01:33:02] <zeeshan> compeltely unbiased
[01:33:09] <zeeshan> http://i.imgur.com/PAMhKL0.gif
[01:33:14] <zeeshan> thats the drawing i used for din2080
[01:33:53] <PetefromTn_> the part under the main clamping groove to the top of the taper distance looks different
[01:34:31] <Tom_itx> the taper is shorter on the stock one
[01:34:49] <zeeshan> tom it shouldnt matter
[01:34:52] <zeeshan> because they start at the same point
[01:34:54] <Tom_itx> but the relief should make up the difference there
[01:35:08] <zeeshan> the bottom line is where the taper is supposed to start
[01:35:14] <Tom_itx> pick a point on the taper and measure the diameter
[01:35:18] <zeeshan> okay
[01:35:19] <zeeshan> good idea
[01:35:31] <Tom_itx> make sure it's accurate
[01:35:59] <PetefromTn_> well I just got finished doing some preliminary measurements on the new 7.5HP spindle motor I received today
[01:36:14] <Tom_itx> measure the base diameter too
[01:36:22] <Tom_itx> (the large taper end)
[01:37:26] -!- uwe_ [uwe_!~uwe_@dslb-088-064-078-234.088.064.pools.vodafone-ip.de] has joined #linuxcnc
[01:37:47] <PetefromTn_> its kind of interesting the original motor had the square profile servomotor shape and the round boss was really large but the mounting holes were outboard of the circle
[01:37:49] <zeeshan> http://i.imgur.com/O7mRWAC.png
[01:37:55] <zeeshan> base diameter is the same of 44.45 mm
[01:38:27] -!- nofxx has quit [Ping timeout: 264 seconds]
[01:38:31] <Tom_itx> check the tool not the drawing
[01:38:40] <Tom_itx> the tool is what's giving you grief
[01:38:40] <zeeshan> i only have one tool
[01:38:44] <zeeshan> how am i supposed to measure the tool
[01:38:47] <zeeshan> i cant cut it
[01:38:48] <zeeshan> :P
[01:38:55] <zeeshan> ill measure the base dia
[01:39:03] <Tom_itx> that's a start
[01:39:08] <PetefromTn_> the new motor has a smaller face circle and the mounting holes are outboard of it but both are inside of the original motors mount circle
[01:39:37] <PetefromTn_> so the good news is that means I can simply make ANOTHER mounting plate
[01:39:46] <PetefromTn_> that is smaller and fits over the original plate
[01:40:17] <Tom_itx> i should add more albums to my playlist
[01:40:19] <PetefromTn_> and I can just machine it to accept the new motors round boss and a hole thru for the shaft as well as four holes to bolt the new motor to it
[01:40:42] <Tom_itx> but not u2
[01:40:44] <PetefromTn_> then I can machine four more holes to the outer edge to bolt it to the existing motor plate
[01:40:47] <Tom_itx> :)
[01:40:59] <PetefromTn_> there's no accounting for taste man...
[01:41:05] <Tom_itx> heh
[01:41:49] <zeeshan> im using a caliper but it should be close
[01:41:54] <zeeshan> i meassre 44.50 mm base
[01:41:59] <zeeshan> pretty close to the 44.45 :P
[01:42:12] <zeeshan> interesting thing though.
[01:42:23] <Tom_itx> what about the small end
[01:42:35] <zeeshan> i didnt check that
[01:42:41] <zeeshan> interesting thing is the overall length
[01:42:42] <zeeshan> seems off.
[01:42:51] <Tom_itx> you will find it
[01:42:57] <Tom_itx> you can't see it but it's there
[01:43:41] <zeeshan> okay
[01:43:44] <zeeshan> something is DEFINTELY up
[01:44:07] <Tom_itx> you could take an impression of it in plaster and check half
[01:44:13] <zeeshan> dude
[01:44:18] <zeeshan> i just measured from where the taper stars
[01:44:20] <zeeshan> *starts
[01:44:25] <zeeshan> overall height of tool
[01:44:29] <zeeshan> im getting like 95.4 mm.
[01:44:36] <Tom_itx> longer ehh?
[01:44:37] <zeeshan> this tool holder is longer ?
[01:44:43] <zeeshan> i know its not the pull stud
[01:44:47] <zeeshan> cause its supposed to be 25 mm long
[01:44:50] <Tom_itx> how do you know?
[01:44:53] <Tom_itx> prove it
[01:44:59] <zeeshan> i measured it
[01:45:08] <Tom_itx> prove it all then you will find the error

[01:46:33] <Tom_itx> hint: you could drill a hole 1.305" in some scrap and fit it over the end to see where it falls
[01:46:42] <zeeshan> dude
[01:46:44] <Tom_itx> dykem the holder
[01:46:49] <zeeshan> this tool holder is longer for sure!
[01:46:56] <PetefromTn_> who's a dude..
[01:47:00] <Tom_itx> well now you're getting somewhere
[01:47:00] <zeeshan> cat40 is supposed to be 68.25
[01:47:04] <Tom_itx> instead of guessing
[01:47:14] <zeeshan> this is like at least 69.8~
[01:47:19] <Tom_itx> zeeshan, do the ring test
[01:47:29] <Tom_itx> then you can cut the holder off to that point
[01:47:31] <PetefromTn_> where did you get that holder?
[01:47:35] <Tom_itx> the base diameter is right
[01:47:42] <Tom_itx> you want the top diameter to be right
[01:47:53] <Tom_itx> unless the taper angle is different too
[01:48:11] <Tom_itx> if it is and the top diameter is right the length will also be right
[01:49:08] <zeeshan> PetefromTn_: accusize
[01:49:15] <Tom_itx> that dimension isn't given but can be calculated from your drawing
[01:49:48] <Tom_itx> 8.2 to the top of the pull stud from the start of the base taper
[01:50:07] <PetefromTn_> https://www.facebook.com/photo.php?fbid=10205921119731683&set=gm.810026285734176&type=1&theater
[01:50:08] <zeeshan> Tom_itx: i can put the holder without the pull stud
[01:50:09] <Tom_itx> less 2.8 to the top of the tool
[01:50:14] <zeeshan> on a flat table
[01:50:17] <zeeshan> and just use a height gage?
[01:50:19] <zeeshan> gauge
[01:50:29] <zeeshan> and measure to the start of the taper
[01:50:32] <zeeshan> its got a groove there
[01:50:40] <Tom_itx> 5.4 taper length
[01:50:46] <Tom_itx> now go measure it
[01:50:56] <Tom_itx> use a height gage and dykem
[01:51:26] -!- nofxx [nofxx!~nofxx@unaffiliated/nofxx] has joined #linuxcnc
[01:52:05] <Tom_itx> no, the 8.2 is wrong...
[01:52:18] <Tom_itx> that's to the start of the upper ring on the pullstud
[01:52:42] <Tom_itx> 5 deg angle then the rest of the pullstud
[01:53:02] <PetefromTn_> I think the pullstud is a good bit different and it the problem
[01:53:08] <PetefromTn_> is
[01:53:31] <Tom_itx> simple measurements will show the error
[01:54:18] <Tom_itx> flag A is the test i first suggested
[01:54:32] <Tom_itx> midpoint diameter or such
[01:55:08] <Tom_itx> the flag isn't described on that page
[01:56:20] <Tom_itx> taper is 8 deg 17 min 50 sec if you have a way to measure that
[02:01:17] <zeeshan> false alarm
[02:01:21] <zeeshan> measured it on the height gauge
[02:01:26] <zeeshan> getting 93.4 mm total length
[02:01:29] <zeeshan> so the tool holder is ok
[02:02:10] * zeeshan is retiring for the night
[02:02:19] <zeeshan> too much f'in around
[02:02:33] <zeeshan> pull stud is the exact same pete
[02:02:38] <zeeshan> look at the din2080 drawing
[02:02:40] <zeeshan> i measure 11.4
[02:02:42] <zeeshan> 7mm groove
[02:02:47] <zeeshan> 25mm total length
[02:03:28] <zeeshan> who knows it might be broken spring packs.
[02:03:59] <Tom_itx> how does it fit with no pullstud?
[02:04:22] -!- tinkerer has quit [Remote host closed the connection]
[02:04:23] <zeeshan> pretty good :)
[02:04:55] <zeeshan> tom did you see the video of me abusing it
[02:04:56] <Tom_itx> and the holder measures the right length and end diameters?
[02:04:57] <zeeshan> by prying?
[02:05:01] <Tom_itx> no
[02:05:09] <Tom_itx> i don't need to really
[02:05:16] <zeeshan> https://www.youtube.com/watch?v=u93js50-J_0
[02:05:26] <zeeshan> i dont think it should be that easy for me to pry on it

[02:06:33] <zeeshan> this is when i wish i had a powercheck II!!!
[02:07:51] <Tom_L> why do you think you have a problem?
[02:08:12] <zeeshan> what ididnt show in that video
[02:08:24] <zeeshan> is that i can spin the tool holder with like 10-15ft-lb of torque
[02:08:25] <Tom_L> does the taper fit snug without prying?
[02:08:27] <zeeshan> and also you can see:
[02:08:41] <zeeshan> https://www.flickr.com/photos/128539016@N05/16204246740/
[02:08:44] <zeeshan> thats the contact pattern
[02:08:51] <zeeshan> its not making full contact
[02:09:41] <Tom_L> i'm gonna stop clicking on flickr now. their fucking ads are beyond annoying
[02:09:47] <zeeshan> lol
[02:09:56] <Tom_L> imagebin
[02:10:34] <zeeshan> http://c4.staticflickr.com/8/7385/16204246740_d322013f58.jpg
[02:11:37] <Tom_L> and you think pulling harder will get you 90% contact?
[02:12:09] <zeeshan> maybe!
[02:12:23] <Tom_L> what are the specs for the pull tension?
[02:12:30] <zeeshan> 3500 lb - 4500lb
[02:12:32] <zeeshan> thats what makes me worry.
[02:12:39] <zeeshan> the fact that i could pry relatively easily
[02:12:41] <zeeshan> and make it move.
[02:12:43] <Tom_L> and what force were you prying with?
[02:12:50] <zeeshan> like 40lb
[02:12:54] <zeeshan> if you consider the fulcrum point
[02:13:02] <zeeshan> and about 6" prybar distance
[02:13:14] -!- lucashodge has quit [Client Quit]
[02:13:16] <zeeshan> its about 640lb of force.
[02:13:31] <Tom_L> so you need to look further up the chain then
[02:13:42] <zeeshan> yea it looks like i need to disassemble this.
[02:13:48] <Tom_L> if the collet measures ok and you're convinced the pullstud is right
[02:13:50] <zeeshan> ott jakob said they'll send me a manual by tomorrow
[02:14:09] -!- jvrousseau has quit [Quit: My Mac has gone to sleep. ZZZzzz…]
[02:14:14] <Tom_L> is it hydraulic or what?
[02:14:17] <zeeshan> yes
[02:14:24] <Tom_L> crank up the pressure
[02:14:34] <zeeshan> well its hydraulic to release
[02:14:38] <zeeshan> belleville washers keep it locked
[02:15:44] <Tom_L> well, you look like a weenie pulling on that so there MUST be something wrong :)
[02:15:54] <zeeshan> hahaha
[02:16:13] <zeeshan> shit
[02:16:17] <zeeshan> the force is in newtons.
[02:16:24] <zeeshan> nm i already converted it.
[02:16:30] <zeeshan> 15000N / 4.48
[02:16:39] <zeeshan> 3348 lb
[02:17:36] <Tom_L> so bolt something to your table with a strain gage attached to it and pull 3347 lbs and see if it moves
[02:17:56] <zeeshan> what do i look like
[02:18:01] <Tom_L> hell i'd be happy with 3346
[02:18:01] <zeeshan> mr scrapyard who has parts everywhere?!?! :D
[02:18:07] <PetefromTn_> HEHE
[02:18:33] <Tom_L> borrow one from the mythbuster telephone book test
[02:18:58] <zeeshan> have you noticed in the startup of mythbusters
[02:19:02] <zeeshan> there is an aloris tool post? :D
[02:19:11] <Tom_L> no
[02:19:24] <zeeshan> when the lathe comes up for like 2 s
[02:19:26] <zeeshan> you'll see it! :D
[02:19:40] <zeeshan> season 16
[02:20:12] <Tom_L> measure the top of the taper like i suggested
[02:20:17] <zeeshan> i did
[02:20:21] <zeeshan> well not w/ the rings
[02:20:23] <zeeshan> just with a mic
[02:20:30] <Tom_L> did you use a 'hole gage' ?
[02:20:34] <zeeshan> as best as i could and get it repeating
[02:20:38] <Tom_L> and dykem it
[02:21:02] <Tom_L> make a hole the proper diameter and slip it over the end perp to the tool
[02:21:25] <zeeshan> easier just to sell the machine
[02:21:26] <zeeshan> :{
[02:21:38] <Tom_L> that's not that hard to do
[02:22:14] <zeeshan> i wish i had a millwright friend
[02:22:19] <zeeshan> they'd know how to fix
[02:22:33] <zeeshan> theyre like the mechanics of the machine world!
[02:22:44] <zeeshan> "tell me the symptoms"!
[02:23:29] <Tom_L> you'll likely need to fix the top end of this contraption
[02:24:10] <zeeshan> http://c1.staticflickr.com/9/8678/16367629596_9e0d6efbdd_h.jpg
[02:24:15] <zeeshan> i think to remove this
[02:24:20] <zeeshan> i need to remove the spring fingers first
[02:24:26] <Tom_L> there's no chips in the collet taper that got smashed in there is there?
[02:24:30] <zeeshan> and this thing should slide out
[02:24:38] <zeeshan> Tom_L: nahh its pretty clean
[02:25:09] <zeeshan> i still think 3300 lb of force
[02:25:10] <zeeshan> is a crap load
[02:25:16] <zeeshan> i should not be able to move it like that
[02:25:30] <Tom_L> what's the lock ring on the splined shaft for?
[02:25:34] -!- humble_sea_bass [humble_sea_bass!U2FsdGVkX1@ma.sdf.org] has joined #linuxcnc
[02:25:42] <zeeshan> thats a good question
[02:25:48] <zeeshan> i think its for when you use the quill
[02:25:55] <zeeshan> it bottoms out on that collar
[02:25:55] <Tom_L> is that an adjustment for tension?
[02:26:01] <zeeshan> yes
[02:26:04] <Tom_L> or length
[02:26:12] <zeeshan> the measurement should be 3.610+/-.010 from the spindle face
[02:26:17] <zeeshan> to the adjustment washer
[02:26:25] <zeeshan> its measuring 3.629
[02:26:42] <zeeshan> which should mean more drawbar force -- i think.
[02:27:45] <Tom_L> ask Mr happyface what's wrong
[02:27:56] <zeeshan> hes sideways
[02:27:58] <zeeshan> taunting me!
[02:30:24] <PetefromTn_> well I think I have a CAD drawing ready to machine a steel mounting plate for the new Lathe motor here...
[02:30:40] <zeeshan> nice :D
[02:31:23] <zeeshan> Tom_L: http://c2.staticflickr.com/6/5612/14996196844_34a7da5cf1_h.jpg
[02:31:27] <zeeshan> i think i should try adjusting it
[02:31:31] <PetefromTn_> trying to decide if I should slot the new plate a bit so I have even more adjustment for belt tension
[02:31:45] <zeeshan> it doesnt have a tensioner?
[02:31:47] <zeeshan> from before
[02:32:03] <PetefromTn_> the original plate is slotted
[02:32:07] <zeeshan> ah
[02:32:22] <PetefromTn_> I am going to make an adapter plate to bolt to the motor that will bolt to this plate
[02:32:39] <PetefromTn_> simple as dirt but it will work
[02:35:10] <Tom_L> z, what's the slot for?
[02:35:20] <Tom_L> is that an adjustment?
[02:35:43] <zeeshan> you use a special tool
[02:35:53] <zeeshan> basically hold the flats, and loosen the socket head cap screw
[02:36:01] <zeeshan> then you spin the washer to adjust like you're sayin
[02:36:13] <Tom_L> so what you waitin for?
[02:36:26] <zeeshan> well the fact that i can pry on it
[02:36:35] <zeeshan> should mean that the belleville washers are owned?
[02:36:43] <Tom_L> possibly

[02:37:12] <zeeshan> yea
[02:37:17] <zeeshan> these guy make a kit
[02:37:35] <Tom_L> so pull it of and clean it good
[02:37:41] <zeeshan> im a bit afraid
[02:37:43] <zeeshan> since i havent worked o nthis
[02:37:45] <Tom_L> of what?
[02:37:51] <zeeshan> i know w/ car springs, they can hurt you pretty good
[02:37:52] <Tom_L> parts is parts
[02:37:54] <zeeshan> same w/ garage door springs
[02:38:01] <zeeshan> thats why i want the manual to disassemble this
[02:38:08] <Tom_L> just treat it like a loaded gun
[02:38:14] <zeeshan> i know that if i completely loosen the adjustment screw
[02:38:18] <renesis> garage door punched me in the face gave me stitches
[02:38:24] <Tom_L> heh
[02:38:25] <zeeshan> i should be able to pull the entire cylinder assembly
[02:38:27] <PetefromTn_> most drawbars have keepers that hold the pack together outside of the drawbar
[02:38:28] <zeeshan> from the top of the head
[02:38:30] <Tom_L> i bet you don't do that again
[02:38:36] <renesis> currently getting collections notices about the hospital bill
[02:38:45] <zeeshan> PetefromTn_: i think its in the cylinder assembly
[02:39:04] <PetefromTn_> is it pneumo or hydro
[02:39:06] <zeeshan> hyd
[02:39:11] <PetefromTn_> shit

[04:08:24] <norias> i can't seem to find any real pricing on linear encoders
[04:08:44] <norias> am i perhaps using the wrong word?
[04:08:59] <unfy> pete: if they suck, then... zomg out $4... otherwise... meh. handy stuff.
[04:09:25] <PetefromTn_> https://www.youtube.com/watch?v=_THbTBY5BBM This is the only youtube video of linuxCNC lathe I can find and I think it has some custom interface that guy made in it.
[04:09:52] <furrywolf> I saw a few videos of linuxcnc doing single-point threading...
[04:09:54] <PetefromTn_> unfy yeah honestly I had some just like that on my RF45 and they worked fine...I am sure they will be adequate for what I need.
[04:10:30] <PetefromTn_> There are TONS of videos of the machines running etc I was looking for one that shows the interface on the screen and what does what and how.
[04:11:10] <PetefromTn_> Been watching the Tormach lathe stuff and knowing it is linuxCNC I am wondering how the stock linuxCNC lathe works. Sure would be nice to be able to get our hands on that Tormach Lathe interface for linuxCNC
[04:12:07] <cradek> there's not much special about the interface when you run a lathe. most show diameter and radius instead of just X. to do stuff you use gcode.
[04:12:07] <norias> eh
[04:12:19] <norias> not a fan of tormach interfaces
[04:12:32] <PetefromTn_> have you seen their lathe interface?
[04:12:41] <norias> i've seen their mill interface
[04:12:47] <norias> and i was kind of let down
[04:13:08] <renesis> dont they run standard software?
[04:13:10] <PetefromTn_> their new linuxCNC based lathe interface looks really well done
[04:13:14] <renesis> its not mach?
[04:13:18] <PetefromTn_> no it is not
[04:13:29] <norias> i thought it was mach3
[04:13:32] <renesis> they have a linuxcnc controller?
[04:13:46] <renesis> i remember thinking from screens it was mach3
[04:13:48] <PetefromTn_> YES I repeat the new interface is linuxCNC based
[04:13:49] <cradek> yeah, they needed the lathe to actually work
[04:13:50] <norias> i think mach is built on emc

[04:19:34] -!- swingley has quit [Ping timeout: 244 seconds]
[04:19:42] <PetefromTn_> I mean the NGCGUI conversational setup allows programming of most parts at the machine from what JT says...
[04:20:02] <renesis> like, i can type: make a pocket 2 inches deep, with 0.2" radius at each corner, using a 3/8" endmill going 50mm/sec, with the lower left pocket corner at X0 two inches above Y origin
[04:20:07] <renesis> and itll do it?
[04:20:28] <renesis> or its like, a question based wizard
[04:20:43] <furrywolf> from what I can find, ibm power cords are the cheapest source of #18 shielded wire. it's cheaper to buy a complete power cord and lop the plugs off than to simply buy 18/3 shielded wire...
[04:20:59] <PetefromTn_> https://www.youtube.com/watch?v=pyiasbfpWHo
[04:21:12] <renesis> furrywolf: theyre shielded?
[04:21:33] <PetefromTn_> that video shows how the interface works on the linuxCNC based slant bed lathe.
[04:21:54] <furrywolf> renesis: good pc power cords are, yes.

[04:22:40] <renesis> wtf is good? a pc cord is an IEC cable, which is a commodity item, which ive never seen a shield on
[04:22:52] <renesis> and ive prob cut into 100 of them
[04:22:57] <PetefromTn_> is NGCGUI something JT created or did he just take it and run with it..
[04:23:16] <Tom_itx> it's an interface you can use with linuxcnc
[04:23:17] <renesis> furrywolf: neat
[04:23:40] <furrywolf> my experience cutting them is about one in five is shielded...
[04:23:41] <PetefromTn_> yeah I understand that. Any videos on using it anywhere?
[04:23:50] <renesis> it looks like an extra tab in axisgui
[04:23:58] <furrywolf> if it feels like a piece of shit cable, it's not going to be shielded. if it's nice thick rubbery wire, it might be.
[04:24:57] <renesis> what side is the shield attached to?
[04:25:02] <Tom_itx> PetefromTn_`, http://linuxcnc.org/docs/html/gui/ngcgui.html
[04:25:39] <Tom_itx> they appear as extra tabs

[04:26:20] <furrywolf> never checked.
[04:26:20] <PetefromTn_> Oh just found some vids on youtube for ngxgui apparently it is for mill stuff too..I thought it was just a lathe thing.
[04:26:36] <Tom_itx> it's for anything you make it
[04:27:11] <Tom_itx> JT-Shop's working on some new lathe stuff right now
[04:27:29] <Tom_itx> you'll have to ask him about it though
[04:27:30] <PetefromTn_> jeez man why are they all freakin' russian or some other language...
[04:28:08] <PetefromTn_> if you can't tell I am really excited about the new CNC lathe and want to learn as much as I can about linuxCNC lathe and NGCGUI
[04:28:23] <Tom_itx> read the docs on it
[04:28:32] <Tom_itx> it shows how to install the routines
[04:29:05] <Tom_itx> and you probably already have some basic ones downloaded and don't even know it
[04:29:37] <PetefromTn_> surely
[04:29:48] <Tom_itx> i added some for the mill
[04:30:03] <Tom_itx> i think most of them were there already i just hooked into em
[04:30:08] <PetefromTn_> man I love linuxCNC.... cannot wait to see this lathe making chips..
[04:32:21] <PetefromTn_> I must say that the Tormach lathe interface is pretty slick... would be sweet to have something similar
[04:32:39] <Tom_itx> http://linuxcnc.org/docs/html/gui/ngcgui.html#_embedding_ngcgui
[04:35:00] <furrywolf> what's the easiest way to check for the fault output from my stepper drivers? it's active low, pulled to an internal 12v supply with a 470 ohm resistor. diode-oring them sounds easy, but without access to that 12v supply, might be problematical...
[04:35:16] <PetefromTn_> is it possible to run simulations from a working linuxCNC machine?
[04:35:51] <Tom_itx> load a sim config and you can
[04:35:59] <Tom_itx> i have lathe sim on mine
[04:36:16] <PetefromTn_> so you don't actually enable any of the machines axes etc..
[04:36:20] <Tom_itx> nope
[04:36:27] <PetefromTn_> just screw around with linuxCNC in simulation
[04:36:28] <PetefromTn_> nice
[04:36:41] <XXCoder1> just turn off power?
[04:36:45] <XXCoder1> to motors that is
[04:36:48] <furrywolf> manual doesn't even tell me if that internal supply is regulated, isolated, etc... presumably it's a loosely regulated supply with a common ground with the power input.
[04:37:02] <furrywolf> and not isolated and running off the step/dir opto supply.
[04:38:35] <PetefromTn_> is your NGCGUI stuff embedded or in pyvcp tabs?

[10:52:41] <Tom_itx> chinese
[10:55:32] <witnit> these look alot closer
[10:56:42] <witnit> the hardest part is finding them the right size it seems
[10:58:30] <witnit> all i really need is 1 inch stroke and the servo rotation, i have intentions on converting another type of older machine to have a servo tapping unit built directly into the machine for tapping parts before cutting them off in the machine
[10:59:35] <witnit> if i could use the same thing as what you listed at direct industry link but maybe just a much smaller version and two position turret instead of that many
[10:59:49] <witnit> that would be ideal
[11:02:02] <witnit> if i didnt need such a fast cycle time I would do it with clutch tapping unit but i need to be able to hit the same spot everytime and be able to swap threads and part length quickly
[11:03:17] <Tom_itx> what material are you tapping?
[11:05:21] <Tom_itx> there's a point the taps won't take it too...
[11:12:11] <witnit> im guessing 1020 its coming from a coldheader shop they are sending samples soon
[11:12:52] <witnit> im not sure if rolltapping is an option due to the wall thickness of the part
[11:14:12] <witnit> Im guessing if i must cut them, I will have to use a spiral tap or i will be pulling shavings out of 3600 holes an hour :/

[16:35:07] <zeeshan> so my current tool holder is correct
[16:36:13] <zeeshan> it must mean release position

[16:37:23] <zeeshan> so its out by almost .030"
[16:37:38] <zeeshan> the question is, what are the symptoms when the distance is too large? :)
[16:38:03] <zeeshan> you should have _more_ clamping pressure i'd think.

[17:00:51] <zeeshan> (if its set to too long of a clamp height)
[17:01:02] <zeeshan> [that makes no sense to me]
[17:01:07] <archivist> spring rate is very high
[17:01:17] <bobo_> This cat is a mostly outdoor type. But cold weather means I am a doorman
[17:01:35] <archivist> so you need to adjust to get the right point on the curve
[17:02:12] <zeeshan> archivist: so at 3.598" , it should be 3350 lb
[17:02:31] <zeeshan> you're saying F = kx , k is non-linear?
[17:02:49] <zeeshan> http://www.globalspec.com/ImageRepository/LearnMore/20123/DimensionsWasherSpring%20graph9153294ca29a4bc6bf3fe017ef72f711.png
[17:02:49] <archivist> it is steep
[17:02:50] <zeeshan> holy cow
[17:02:53] <zeeshan> its highly non-linear
[17:03:10] <zeeshan> if you over compress
[17:03:52] <zeeshan> dependant on the height ..
[17:04:25] <archivist> I did damage my rollers when making a printer developing roller mechanism compressed with those "washers"
[17:05:41] <archivist> needed 2 tons per linear inch, if the paper wrinkled, guess the area :)
[17:06:42] <zeeshan> metric tons? :)
[17:07:18] <archivist> nah USA tons it was an american technology
[17:07:41] <bobo_> The adjust tool-----might consider having place for coller on tube to measure distance from for setting fingers distance to spindle face
[17:09:42] <bobo_> Saw on your PDF #2 the use of loctite
[17:09:45] <OneTimePad> how?
[17:10:22] <OneTimePad> did lock washers slip?
[17:13:17] <zeeshan> yea bobo
[17:13:26] <zeeshan> not sure what thats for.
[17:13:34] <archivist> 8 inches of rollers, when the paper wrinkles all the pressure is on a small area so 16 tons
[17:14:17] <zeeshan> http://i.imgur.com/Ykt0NMu.png
[17:14:20] <zeeshan> this is the tool for adjustment
[17:14:29] <OneTimePad> another day older and deeper in debt?
[17:16:54] <malcom2073> Ya load 16 tons
[17:18:12] <archivist> case hardened but not deep enough
[17:21:34] <bobo_> zeeshan what is your current thinking about th e-bay Mikron manual ?

[18:35:47] <malcom2073> I'm getting dejavu
[18:35:53] <malcom2073> hackaday just posted that like a week ago didn't they?
[18:36:09] <malcom2073> New revolutionary system, should call it something... ser something, servo maybe? Sounds like a good name, quick, patent it!
[18:37:08] <malcom2073> What's funny, they started with DC motors for the extruder, and rather than sticking an encoder on it, went to steppers
[18:40:44] <bobo_> malcom2073 get back to the drain stopper repair kit ------my 401k is in need !
[18:41:04] <ssi> hey gu\ys
[18:41:12] <ssi> I have a thing I'm trying to do I could use some advice on
[18:41:17] <malcom2073> bobo_: I'm still waiting on the guy to get back from arizona so I can pick up the damm machine, much less the retrofit :P
[18:41:19] <malcom2073> one thing at a time haha
[18:41:37] <ssi> I'm trying to fit a tailwheel to a new tailspring, the tailspring is tapered and spring steel, and I can't really turn it because it's long and bent
[18:41:48] <ssi> the tailwheel has a tapered socket on it that's kinda dorked up
[18:41:52] <ssi> it's aluminum
[18:42:14] <ssi> best way I can think to clean it up is with a tapered reamer, but I'm not sure I can get an appropriate reamer
[18:42:18] amnesic is now known as amnesic_away
[18:42:45] <ssi> the spring seems to measure about 0.0135"/inch taper, which is way shallower than any morse
[18:43:06] <Tom_itx> boring bar?
[18:43:18] <ssi> it's .641" an inch from the small end, and .668" 3" from the small end
[18:43:23] <ssi> not sure how to bore a taper on the mill
[18:43:39] <Tom_itx> no lathe?
[18:43:41] <ssi> I could bore a taper on the lathe, but I can't hold the tailwheel body on the lathe
[18:43:46] <Tom_itx> oh
[18:44:08] <Tom_itx> how outta whack is it?
[18:44:18] <ssi> enough that I can't make the new spring seat
[18:44:43] <ssi> I could probably touch it up with sandpaper and make it work, but I'd like to do something a bit more precise
[18:45:13] <Tom_itx> i was gonna say why not wrap some 400-600 around the shaft and see if you can clean it up a bit
[18:45:25] <Tom_itx> insert the shaft in the wheel
[18:45:36] <Tom_itx> and manually turn the wheel
[18:46:20] <ssi> https://pbs.twimg.com/media/B8nnMV9IcAIwvmb.jpg:large
[18:46:25] <ssi> that's the tailwheel body, fwiw
[18:46:28] <ssi> the bottom end is the taper end
[18:46:45] <ssi> the tapered tailspring goes in that socket, then gets cross drilled and bolted
[18:47:32] <ssi> if I had something cnc I could taper bore :P
[18:48:58] <PetefromTn_> which side has the taper the long side or the short side?
[18:49:04] <ssi> the long side
[18:49:15] <Tom_itx> aviation epoxy
[18:49:17] <Tom_itx> :)
[18:49:21] <PetefromTn_> how deep is it?
[18:49:21] <Tom_itx> that'll fill the gap
[18:49:25] <ssi> 1.75
[18:49:29] <Tom_itx> that pink stuff...
[18:49:56] <ssi> I have gallons of epoxy, but that's not the right answer here :)
[18:50:25] <PetefromTn_> I don't see why you could not put it in your lathe if you are talking about the long side taper.. do you have a steady rest?
[18:50:38] <ssi> yes, I have a steady
[18:50:51] <Tom_itx> that's your best bet so far
[18:50:53] <ssi> I guess I could center it in the steady and run it with a four jaw
[18:51:04] <PetefromTn_> can't you hold the part in the four jaw on the top
[18:51:07] <PetefromTn_> LOL yeah
[18:51:33] <PetefromTn_> hold it in the four jaw and indicate the taper on the outside of the steady rest and bore it
[18:51:44] <PetefromTn_> with the compound if it has enough travel
[18:51:54] <ssi> I have a taper attachment
[18:51:55] <PetefromTn_> or with your taper attachment as I recall you have one
[18:51:57] <Tom_itx> what angle are the 2 holes to each other? they're not 90 deg
[18:52:04] <ssi> no, they're not 90
[18:52:13] <ssi> 80 maybe
[18:52:15] <ssi> dunno exactly
[18:54:13] <PetefromTn_> might find that the OD is not concentric to the taper id of course so you might have to screw around adjusting it until you get the old taper to run as true as possible. If you have the male part you can make it the same regardless

[20:16:49] <LeelooMinai> Hmm
[20:17:16] <LeelooMinai> So, this spindle bracket of mine, which looks like this one: http://www.aliexpress.com/item/65MM-DIAMETER-CAST-ALUMINIUM-BRACKET-FOR-CNC-ENGRAVING-MILLING-MACHINE-SPINDLE/1704993561.html
[20:18:32] <LeelooMinai> It seems that looking from top it's not a rectangle, but one side is 2mm shorter - it tapers. My guess it's on purpose so it can "wedge" itself into something, right?
[20:19:26] <norias> hmm
[20:19:30] <norias> i don't see a top view
[20:19:39] <PetefromTn_> is it cast?
[20:19:46] <LeelooMinai> Yes, it's cast
[20:19:56] <LeelooMinai> Cast and sandblasted apparently
[20:20:11] <PetefromTn_> they probably did not worry about the dimensions along the side so you cannot rely on it being straight or square
[20:20:28] <PetefromTn_> they probably bored it from the top or bottom and then faced that side or both
[20:20:33] <PetefromTn_> possibly
[20:20:49] <LeelooMinai> Well, but 2mm difference, that's a bit extreme - it almost seems it's done on purpose
[20:21:00] <PetefromTn_> I cannot imagine why

[20:21:25] <PetefromTn_> is that link the exact one you have
[20:21:41] <LeelooMinai> PetefromTn_: Well, as I said, maybe it's so it wedges itself?
[20:21:43] <Connor> Probably just a bad casting..
[20:21:50] <LeelooMinai> Yes, it's the same one as on the link

[20:26:12] <marmite> na its a mac adress :D
[20:26:27] <marmite> well the end digits
[20:26:51] <Connor> marmite: the rubber should only go under the part..
[20:27:01] <norias> wait
[20:27:08] <norias> which way was it cast?
[20:27:12] <marmite> what rubber?
[20:27:15] <norias> if it's die cast, it needs draft
[20:27:20] <norias> (the aluminum part)
[20:27:28] <marmite> its not casted
[20:27:29] <marmite> casted
[20:27:37] <marmite> there are milling marks on it
[20:27:48] <Connor> marmite: the black rubber around the edge....
[20:27:58] <norias> LelelooMinai said it was cast
[20:27:59] <Connor> you can remove it.. and place it around other spots.
[20:28:12] <marmite> yes i know
[20:28:20] <marmite> i have one on the end of the plastic that you dont see
[20:28:27] <PetefromTn_> marmite nice man..
[20:28:33] <marmite> PetefromTn_: ty ^^
[20:28:50] <marmite> works suprisingly well
[20:29:00] <marmite> that vacuum tank does so mutch :D
[20:29:13] <Connor> What does the tank do ?
[20:30:02] <PetefromTn_> it supposedly helps when you switch it on and off to help with a quick suck down so the compressor does not do all the work
[20:30:05] <LeelooMinai> I was talking about my spinfle bracket - it's cast, not that thingy... what is it even - some suction-based clamping system?
[20:30:24] <marmite> PetefromTn_: yeah ^^ iam going to have a valve to turn of and on.
[20:30:30] <marmite> and it helps even if there is a leak
[20:30:31] <PetefromTn_> but in that situation it is not doing too much I don't think but making it take longer to get suctioin
[20:30:33] <norias> LeelooMinai: yeah, your spindle bracket. I think it's die cast, and the 2mm is draft.
[20:30:52] <LeelooMinai> What is a draft? :)
[20:31:14] <marmite> PetefromTn_: rightnow it helps combat air leak
[20:31:18] <norias> The smiley face makes your question ambiguous to me.

[20:31:45] <LeelooMinai> I know only of a draft made by leaving door open:)
[20:31:58] <LeelooMinai> And drafting paper?
[20:31:59] <norias> molds have to have an angle in them
[20:32:02] <PetefromTn_> draft is a taper basically
[20:32:08] <norias> so you can pull the part out
[20:32:17] <LeelooMinai> A, right, I see... that makes sense.
[20:32:27] <norias> die casting is like molding of aluminum (as opposed to sand cast)
[20:32:41] <norias> if you are trying to make that part cheap, and make millions
[20:32:44] <norias> i'd die cast it
[20:32:45] <LeelooMinai> I thought it's tapered to allow for some wedging maybe
[20:32:53] <norias> and i'd put a bunch of draft on it
[20:33:03] <norias> so that the parts fall right out of the die
[20:33:14] <norias> and the die design is simpler
[20:33:27] <norias> i.e. everything is as cheap as possible
[20:33:35] <LeelooMinai> Yes, now I get it - I was pretty sure the 2mm difference was there not by accident, because the whole bracket seems to be designed this way

[20:34:55] <LeelooMinai> I need to make 4 holes for m8 screws in it using a drill press - I hope I do not mess it up
[20:35:02] <PetefromTn_> so the 2mm angle is along the long edge or vertically from the side along the short edge or the flange lip?
[20:35:28] <norias> "front to back" as the part is displayed
[20:35:29] <LeelooMinai> The flanges taper but the main body follows that taper too
[20:35:32] <norias> is my understanding
[20:35:42] <norias> think about the die for this
[20:35:53] <norias> you'd want the bored to be along the axis of pull for the die
[20:36:07] <PetefromTn_> yeah I understand how the die would be cast I am just not sure that is the taper she is talking about
[20:36:21] <norias> i think so
[20:36:35] <norias> i could be wrong, but that's the most reasonable thing i can see

[20:37:26] <LeelooMinai> Here's exaggerated view from top: http://i.imgur.com/3VYoXcK.png
[20:37:40] <PetefromTn_> either way it does not matter she is going to be drilling it in a drill press and screwing it down just can't rely on any of those tapered surfaces to be reference surfaces. if it does not appear to me machined it is not square or straight
[20:37:57] <norias> right
[20:38:20] <norias> i'd want to machine refference surfaces
[20:38:25] <norias> then machine the bore
[20:38:35] <norias> personally
[20:38:41] <LeelooMinai> There will be 4 holes, so they will not form a rectangle I guess - I will need to offset two of them so they are on the centre of the "lip"
[20:39:14] <norias> or make slots
[20:39:18] <PetefromTn_> sure... does the bored end have a flat surface square to the bored hole?
[20:39:24] <norias> never forget the power of slots
[20:39:38] <LeelooMinai> Slots where/what for?
[20:39:44] <norias> instead of through holes
[20:39:45] <PetefromTn_> so you can tram it in.
[20:40:06] <LeelooMinai> Making slots on a drill press is not really a good idea:)
[20:40:07] <PetefromTn_> unless your Z axis has adjustability built in
[20:40:12] <norias> you can do slots on a drill press
[20:40:20] <norias> drill two holes
[20:40:24] <norias> file the flat
[20:40:30] <PetefromTn_> you are going to want to make it adjustable somehow so you can make the spindle square to the table surface
[20:40:51] <LeelooMinai> I will have some adjustability as the holes will be 9mm for 8mm screws
[20:41:12] <norias> i'd make one hole tight
[20:41:13] <norias> er
[20:41:22] <norias> so it's a "pivot point"

[20:42:08] <LeelooMinai> Hmm, and how will it help?

[20:42:44] <norias> debatable. I like to have one known pivot point in a setup
[20:42:55] <norias> Pete disagrees. Such is life.
[20:43:36] <LeelooMinai> Ok, I guess it's time to put the measurements on that thing
[20:43:42] <PetefromTn_> take a square and try to find the surface that is closest to perpendicular to the bore and reference that.. drill your holes with enough clearance to be able to adjust it enough
[20:44:27] <PetefromTn_> once you get it assembled and tram it in you can always add some alignement pins to help keep it located

[20:55:10] -!- archivist_herron [archivist_herron!~herron@herronwindows.co.uk] has joined #linuxcnc
[20:55:35] <PetefromTn_> Ok so like 5x7 inches or so..
[20:56:01] <marmite> 8,3 x 5.2
[20:56:24] <PetefromTn_> is that the clamping area? or the OD
[20:56:36] <marmite> oh dont know tbh
[20:56:56] <PetefromTn_> either way looks like it works nice
[20:57:07] <marmite> dont External Dimesnions- Measure: 212 x 132 x 12 mm
[20:57:08] <marmite> Clamping area: 200 x 120 mm
[20:57:31] <PetefromTn_> I am going to need to buy or make something like that here soon.
[20:58:03] <marmite> oh
[20:58:06] <marmite> great tables
[20:58:39] <marmite> http://www.ebay.com/itm/Vacuum-table-VT3020R-for-CNC-Machining-and-Milling-/171653359598?pt=UK_BOI_Metalworking_Milling_Welding_Metalworking_Supplies_ET&hash=item27f75667ee they have larger tables aswell
[20:58:42] <PetefromTn_> meeting with a customer here later this afternoon to get a deposit for some work and when I am finished I will be heading to Horrible Freight to get some sort of vacuum solution and hopefully they sell some kind of vacuum tubing.
[20:58:53] <marmite> ahh :)
[20:59:27] <PetefromTn_> yeah those do look nice actually but it says they may not ship to USA
[20:59:35] <marmite> ahh
[20:59:53] <marmite> theres gotta be a good seller in the usa for those kind of tables
[21:00:26] <PetefromTn_> yeah there are quite a few but most are real proud of their products hehe

[21:22:55] <Connor> Is it the battery holder boxes?

[21:43:53] <Tom_itx> shouldn't be that difficult
[21:45:42] <Tom_itx> you don't need that whole grid they did on that one
[21:45:56] <Tom_itx> it just causes leaks if you don't plug the channels
[21:46:22] <PetefromTn_> actually this part will be getting a 2 part run dedicated fixture that will be kurt vise mounted
[21:46:43] <Tom_itx> if you're making one for a specific part it's pretty easy
[21:46:47] <PetefromTn_> but I would like to build or buy something like that Vacmagic VM300 pallet system for the machine
[21:46:55] <PetefromTn_> yeah it is easy
[21:47:28] <Tom_itx> my friend had a bolt down system but i forget who made the fixture screws for it
[21:47:47] <PetefromTn_> just gonna machine a series of slots inside the part perimeter interlocking to a center port that will be drilled and tapped thru to accept the vacuum fitting from underneath
[21:48:10] <Tom_itx> it's just 2 bolt hole grid patterns one threaded and the other reamed for dowels
[21:48:20] <Tom_itx> the threaded ones you can get various fixture clamps for
[21:48:32] <Tom_itx> even to hold your vise
[21:48:43] <zeeshan> tgif
[21:48:46] <PetefromTn_> link?
[21:48:51] <Tom_itx> agreed
[21:49:00] <Tom_itx> like i said, i don't remember the brand of fixtures
[21:49:08] <Tom_itx> it was a very nice setup though
[21:49:08] <PetefromTn_> OK
[21:49:09] <zeeshan> i hope to figure out this drawbar issue today
[21:49:16] <Tom_itx> compared to how we used to do it
[21:49:26] <PetefromTn_> I am pretty impressed with that VM300 system
[21:49:32] <Tom_itx> link?
[21:49:34] <PetefromTn_> it is the best of both worlds I think
[21:49:35] <MrSunshine> did some realtime tweaks to my linuxcnc computer ... and the stepper motors sounds totaly different now when moving than before =)

[21:50:43] <Tom_itx> everything's gotta be a video anymore it seems....
[21:51:03] <PetefromTn_> tells the story better...
[21:51:09] <zeeshan> hell no
[21:51:22] <zeeshan> if supplements a pdf :-)
[21:51:23] <Tom_itx> i got no sound anyway
[21:51:33] <zeeshan> Tom_itx: why no sound
[21:51:41] <Tom_itx> not on this pc
[21:52:07] <Tom_itx> i wouldn't pay for the fancy tooling... i'd make it
[21:52:19] <PetefromTn_> I plan to
[21:52:27] <PetefromTn_> but even that won't be cheap
[21:52:50] <Tom_itx> all we did was make aluminum plates to fit the parts we needed to vaccuum hold
[21:52:55] <PetefromTn_> gonna take a large thick base plate for the main part
[21:52:56] <Tom_itx> which weren't that many
[21:53:07] <Tom_itx> large thin aluminum usually
[21:53:09] <PetefromTn_> then another plate to hold it down with...
[21:53:24] <zeeshan> just looks like a plate w/ holes in it :P
[21:53:27] <zeeshan> and a vacuum nanifold
[21:53:27] <Tom_itx> fine if you have lots of Z
[21:53:28] <zeeshan> manifold
[21:53:46] <PetefromTn_> it actually has the venturi and stuff inside the base
[21:53:55] <PetefromTn_> it is honestly very well done IMHOP
[21:54:03] <zeeshan> wait
[21:54:07] <PetefromTn_> wish I could afford it
[21:54:09] <zeeshan> it uses air flow to generate vacuum?
[21:54:17] <PetefromTn_> but they want almost 3k for the damn thing
[21:54:20] <PetefromTn_> yeah
[21:54:24] <Tom_itx> takes alot of air
[21:54:29] <zeeshan> thats a pretty crappy way of generating vacuum
[21:54:31] <PetefromTn_> 70PSI
[21:54:37] <Tom_itx> and vaccuum pumps are noisy as all getout
[21:54:40] <zeeshan> psi has nothing to do with it
[21:54:53] <PetefromTn_> I'm fully aware how it works
[21:55:01] <zeeshan> then you should know psi has nothing to do with it
[21:55:03] <PetefromTn_> just telling you
[21:55:14] <Tom_itx> we had a large tankless screw compressor in a room by itself so air was never a problem
[21:55:25] <PetefromTn_> you can research the product if you want or not
[21:55:41] <zeeshan> i dont need to research the product to understand basic fluid principles
[21:55:52] <Tom_itx> it sucks
[21:55:53] <Tom_itx> :D
[21:56:00] <zeeshan> that generating vacuum using venturi is grossly inefficient
[21:56:09] <zeeshan> a vacuum pump is a far better option
[21:56:23] <PetefromTn_> OK
[21:56:25] <Tom_itx> PetefromTn_, those mitee bite products were very similar to what my friend uses
[21:56:36] <PetefromTn_> yeah I really like those too
[21:56:40] <zeeshan> Tom_itx: those screw compressors are sexy
[21:56:41] <zeeshan> but $$$$$$4
[21:56:43] <zeeshan> theyre so quiet
[21:56:44] <PetefromTn_> they make a lot of good stuff
[21:56:53] <Tom_itx> this one wasn't quiet
[21:56:57] <Tom_itx> it was big
[21:57:02] <zeeshan> 150 cfm ?
[21:57:08] <zeeshan> i was next one that did 150 cfm
[21:57:09] <Tom_itx> that's why we put it in a room by itself
[21:57:14] <zeeshan> it just humms
[21:57:15] <zeeshan> haha
[21:57:16] <Tom_itx> i don't know the cfm but it was alot
[21:58:04] <PetefromTn_> that vacuum pallet system would be kickass on my Cincinatti
[21:58:19] <Tom_itx> if you need alot of parts that need vaccuum held
[21:58:22] <PetefromTn_> a fixture for vacuum clamping, a fixture for vise hold down etc..
[21:58:23] -!- FinboySlick has quit [Quit: Leaving.]
[21:58:33] <PetefromTn_> not really
[21:58:42] <Tom_itx> otherwise you're just wasting power clamping something
[21:58:54] <PetefromTn_> think of it as a quick change pallet system moreso than just a vacuum clamping
[21:59:10] <Tom_itx> factor that in your part cost too
[21:59:11] <zeeshan> PetefromTn_: correct me if im wrong
[21:59:30] <zeeshan> but cant you just drill a buncha holes in a plate that connect to a vacuum manifold
[21:59:38] <zeeshan> and have a seal around the whole thing and hook it up to a vac pump
[21:59:47] <zeeshan> and do the same thing?
[22:00:01] <Tom_itx> got me an S5 couple days ago, not much different than the S4 but i'm kinda liking it...
[22:00:12] <Connor> S5 ?
[22:00:13] <PetefromTn_> there are lots of ways to make a vacuum plate man..
[22:00:14] <zeeshan> Tom_itx: does it have sound?
[22:00:20] <Tom_itx> of course it does
[22:00:22] <Tom_itx> it's a phone
[22:00:24] <zeeshan> :-) im trolling

[22:00:43] <Tom_itx> not from china eitehr
[22:00:59] <Tom_itx> they'll both probably get here the same time
[22:01:04] <zeeshan> you know i have never done a calculation like this
[22:01:11] <Tom_itx> the one from china has been stuck in chicago all week
[22:01:13] <zeeshan> if you have 29 inhg vac pressure
[22:01:14] <Tom_itx> probably customs
[22:01:18] <zeeshan> how much clamping force you hjave
[22:01:32] <zeeshan> vac pressure => vacuum i mean
[22:01:36] <Tom_itx> depends on the surface area
[22:01:41] <zeeshan> "lack of pressure"

[22:08:11] <zeeshan> correct me if im wrong but, assuming perfect vacuum & 10 holes of 1/2" diameter, the clamping force will be F = 14.7*10*(pi/4)(.5)^2 = 28.86 lb
[22:08:18] <zeeshan> something seems off
[22:08:25] <zeeshan> thats not much clamping
[22:08:45] <andypugh> 10 1/2” holes isn’t much area
[22:09:16] <zeeshan> even if its 40 holes
[22:09:31] <zeeshan> thats like 120lb
[22:09:31] <Tom_itx> andypugh what you working on now?
[22:09:45] <andypugh> But you are likely to get the full flat surface of the part as area rather than just the holes.
[22:09:55] <zeeshan> why
[22:09:58] <andypugh> Tom_itx: Finishing off the headlights for the Ner-a-car
[22:10:09] <zeeshan> i guess you have a seal around it
[22:10:09] <Tom_itx> ahh i thought you were done with those
[22:10:15] <zeeshan> to raise the part up slightly.
[22:10:15] <unfy> a 1/2 inch hole has a surface area of ~ 1/5th of an inch ?
[22:10:16] <zeeshan> gotcha.
[22:10:27] <Tom_itx> zeeshan we sealed the perimeter and any pocket cutouts
[22:10:30] <unfy> er, 1/5th square inches
[22:10:34] <Tom_itx> it would pull on the whole part
[22:10:36] <andypugh> I made the shells, but they have brackets and fittings to hold the fronts on etc.
[22:11:04] <unfy> so... 10 of those get you a 2 square inches ?
[22:11:26] <unfy> that's not a whole lot of of area for a clamp.
[22:11:31] <zeeshan> okay ill gage an idea of how much clamp force there is. take a sample 6"x6"x.125" 6061 al plate, so its just F = 14.7*6*6 = 97lb
[22:11:48] <zeeshan> a hell of a lot less than
[22:11:49] <zeeshan> 2 toe clamps
[22:11:50] <zeeshan> :D
[22:12:09] -!- TTN has quit [Quit: gnight :)]
[22:12:12] <Tom_itx> it's spread over a larger surface area

[22:12:26] <zeeshan> well im assuming 6x6 flat square plate
[22:12:28] -!- jvrousseau has quit [Ping timeout: 272 seconds]
[22:12:29] <zeeshan> so thats the surface area..
[22:12:51] <zeeshan> andypugh: they look nice
[22:12:52] <zeeshan> can i have one
[22:12:54] <unfy> zee: he's saying a toe clamp's surface area is tiny compared to your 6x6 plate
[22:12:54] <zeeshan> :-)
[22:13:08] <Tom_itx> andypugh, those are nice.. did you make castings for them?
[22:13:35] <andypugh> No, the brackets are turned on a lathe, milled to shape, then bent to the right curve.
[22:14:21] <andypugh> I can’t decide if I want to get into casting to make the mating parts.
[22:16:12] <zeeshan> so a fair comparison would be, lets say 2 toe clamps, 4000lb each, contact area of .5"x.5" , 32000 psi total, take that F = 32000psi*
[22:16:15] <zeeshan> er
[22:16:22] <zeeshan> assuming 8000 lb toe clamp force
[22:16:39] <zeeshan> if you normalize it over 6"x6", you end up getting 222lb

[22:16:51] asheppard is now known as sheppard
[22:16:53] <zeeshan> so vacuum clamping seems prretty good now!
[22:17:00] <zeeshan> nice.
[22:17:08] <andypugh> I don’t trust your normalisation.
[22:17:15] <Tom_itx> tape works too
[22:17:16] <zeeshan> haha its a really crapppy way
[22:17:25] <zeeshan> but im trying to get a relative sense.
[22:18:08] <andypugh> You need to compare 222 x mu with 4000. Which looks worse.
[22:18:24] <zeeshan> why friction
[22:18:33] <Tom_itx> that much force on a toe clamp will cause warping too
[22:19:03] <andypugh> Because you are trying to counteract cutting forces, not forces lifting the workpiece.
[22:19:17] <zeeshan> GOOD point
[22:19:25] <zeeshan> okay vacuum table looks not as good anymore again :(
[22:19:39] <zeeshan> but it does have the advantage like tom is saying of uniform clamping
[22:19:43] <zeeshan> which is pretty important for thin stuff
[22:20:01] <zeeshan> so basically when using vacuum tables, take it easy
[22:20:07] <andypugh> Look at it this way instead. How much force can you hang on the end of that 1/4” carbide bit before it snaps?
[22:20:20] <Tom_itx> you're not gonna be taking 3/8" passes with a shell mill on those types of parts
[22:21:09] <andypugh> If you prefer, put the cut parameters into this web page, it calculates cutting forces: http://zero-divide.net/?page=fswizard
[22:21:26] <Tom_itx> i have that on my phone

[22:23:39] <zeeshan> i might have to turn this on the lathe
[22:23:51] <zeeshan> and then just weld on keys
[22:24:05] <andypugh> How many do you need?
[22:24:08] <Tom_itx> one
[22:24:11] <zeeshan> just one
[22:24:13] <zeeshan> its my adjustment tool
[22:24:16] <zeeshan> for the drawbar
[22:24:46] <andypugh> I would turn it on the lathe then make the drive dogs with a hacksaw.
[22:25:05] <zeeshan> thats not a bad idea
[22:25:08] <zeeshan> it doesnt need to precise
[22:25:10] <andypugh> It’s only 4 cuts with the saw. Then perhaps a bit of filing. Don’t disparage hand-work.

[22:39:34] <Jymmm> Although, today, I'd use silicone

[22:40:34] <Tom_itx> what year is it?
[22:40:58] <Jymmm> furrywolf: clean surface, kneed, apply, done. no need to wait to dry/cure.
[22:41:05] <Tom_itx> ahh nm 1914
[22:42:08] <furrywolf> my van window uses this stuff to seal and bolts to hold the glass in place.

[22:45:06] <furrywolf> I've used that stuff on rvs. it's not a tenth as gooey, sticky, or messy as ribbon sealer. heh.
[22:45:22] <furrywolf> it also cracks much sooner

[22:46:30] <Jymmm> But that "putty tape" is kinda unusual unless you've worked with it before.

[22:48:06] <Jymmm> zeeshan: does it work wet/underwater?
[22:48:28] <zeeshan> it should because its meant to be used for the plastic liner behind your door panel
[22:48:33] <zeeshan> that keeps water from inside your car
[22:48:51] <Jymmm> zeeshan: once cured. But I mean when applying
[22:49:00] <zeeshan> no idea on that :)
[22:50:04] <furrywolf> most liquid products don't work underwater. Mr Sticky's Underwater Epoxy (or some very similar name) does, as does many asphalt products, like wet patch.

[22:53:38] <Jymmm> you definition.
[22:53:41] <Jymmm> tour
[22:54:01] <Jymmm> you embelish way too much to be taken at face value =)
[22:54:23] <Jymmm> It might be like crazy glue, which is not for everything
[22:54:43] <furrywolf> I have never had it successfully stick to anything. as far as I can tell, its only value is that it holds the shape you set it in, and is more useful as a molding compound than an adhesive.
[22:54:58] <furrywolf> it doesn't stick at all, but it does set in the shape you set it, with minimal shrinkage, rock hard.
[22:55:14] <Jymmm> Nice, that might actually be a good thing/use
[22:56:27] <furrywolf> I think it's just a fundamental issue with stick epoxies... by being very stiff, they can't fill the tiny irregularities on surfaces that result in good bonds, instead just sitting on the high points.
[22:57:07] <Jymmm> JB used to have the blk/wht two part putty, I haven't seen that in years.
[22:57:28] <Jymmm> might be good for filler

[23:00:17] <Jymmm> silicone?
[23:00:36] <furrywolf> silicone would burn instantly.

[23:00:53] <Jymmm> Have you ever taken a torch to cured silicone?
[23:01:12] <Jymmm> silicone is just unoxidized sand

[23:01:51] <furrywolf> you can buy high-temp silicone. it's usually copper-colored. it's still rated for far cooler than an exhaust manifold gets.
[23:01:54] <Jymmm> boiing point ​5909 °F)
[23:02:13] <Jymmm> if your engine gets that hot, you got bigger issues =)
[23:02:15] <furrywolf> silicone exposed to exhaust browns and cracks quickly.
[23:03:11] <furrywolf> you can buy silicone tubing for nitro engines, and even there it fails, just not quickly.
[23:03:23] <Jymmm> NFC if it has a chemical reaction.
[23:03:48] <furrywolf> exhaust leaving the engine is HOT.
[23:03:55] <furrywolf> the exhaust manifold is HOT.
[23:04:28] <furrywolf> exhaust parts glowing cherry red is not uncommon.
[23:04:51] <Jymmm> sure, so areounf 1200F.
[23:05:14] <PCW> HT silicone is what 600F max?
[23:05:30] <Jymmm> regular is 572F
[23:05:30] <furrywolf> somewhere around there, yes
[23:05:50] <furrywolf> anyway, I speak from experience. you can not silicone an exhaust manifold. :P
[23:06:00] <Jymmm> unless they are doing the mareting gimmick thing
[23:06:05] <furrywolf> I even tried aluminum and it burnt that.
[23:06:19] <furrywolf> wrapping it with foil and hoseclamping it.
[23:06:39] <Jymmm> 650F close enough http://www.permatex.com/products-2/product-categories/gasketing/gasket-makers/permatex-high-temp-red-rtv-silicone-gasket-detail
[23:07:24] * furrywolf wonders what, exactly, jymm's point is
[23:07:59] <CaptHindsight> furrywolf: do you want an epoxy that works/cures under water?
[23:08:05] <PCW> polyimide would fare better but dont think there are any rubbery polyimides
[23:08:12] <furrywolf> capt: no, someone else was asking about it.
[23:08:27] <Jymmm> I've used silicone around 900F, but not sustained. I thought it was higher temp than exhaust manifold.
[23:08:49] <furrywolf> the only things that withstand the temperature on a manifold are the silica/ceramic/etc stuffs, and they're all too brittle and crack with thermal expansion.
[23:08:59] <CaptHindsight> how about sodium silicate?
[23:09:38] <CaptHindsight> well yeah if the manifold flexes, depends on the size of the crack as well
[23:09:40] <furrywolf> that would be one of the silicas, yes. :P
[23:09:55] <CaptHindsight> we used to weld them
[23:10:29] <PCW> Hmm didnt know there were polyimide photoresists
[23:11:13] <Jymmm> Stove Seal is rated at 3000F, says non cracking http://www.jacomanufacturing.com/?a=prod
[23:11:55] <CaptHindsight> refractory cements
[23:13:03] <furrywolf> stove seal cracks everywhere it's used, even stoves. heh.
[23:15:18] <furrywolf> capt: welded cast iron manifolds have an annoying habbit of promptly recracking...
[23:16:07] <CaptHindsight> use the old one as a mold and sand cast
[23:16:40] <andypugh> Melting cast iron is not trivial in a domestic kitchen.
[23:17:16] <CaptHindsight> I have a feeling andy has done it there
[23:17:31] <andypugh> No, I have never actually done any casting at home.
[23:17:50] <furrywolf> heh, my solution was to find someone with a non-cracked manifold, and give them $40.
[23:17:52] <andypugh> I have tended to work at places with foundries.
[23:18:21] <furrywolf> rather than cast, if I had to fab one, I'd do welded tube...
[23:18:26] <andypugh> (Not that I have access to the casting plant at Ford, sadly)
