[00:32:33] <zeeshan> if it randomly rotates

[01:11:57] <unfy> heh
[01:12:27] <furrywolf> a dana 60 front with 5.13 gears... not easy to do.
[01:18:04] <The_Ball> arg these mozzie bites are driving me insane
[01:22:20] <zeeshan> http://i.imgur.com/BrbNQE4.png
[01:22:23] <zeeshan> lol that was my original idea
[01:22:28] <zeeshan> it some how evolved to this
[01:22:35] <zeeshan> http://i.imgur.com/l6ZpSGS.png
[01:23:43] <The_Ball> that's neat, blog logo?
[01:24:06] <zeeshan> my page
[01:24:09] <zeeshan> main page i mean
[01:24:19] <The_Ball> Did you make it in Inkscape?
[01:24:22] <zeeshan> no
[01:24:23] <zeeshan> solidworks
[01:24:34] <furrywolf> you know what I like? underlined purple links.
[01:24:58] <zeeshan> i dont have time to learn a photo editing software
[01:24:59] <zeeshan> haha
[01:25:12] <zeeshan> is inkscape comparable to photoshop?
[01:25:36] <The_Ball> not really, it's only for vector graphics
[01:27:21] <The_Ball> zeeshan, I just started toying with SW, it's very good
[01:27:51] <furrywolf> I need to find a good open-source cad program.
[01:28:10] <zeeshan> the_ball yea its very powerful
[01:28:23] <The_Ball> furrywolf, have you tried FreeCAD? It's pretty good and improving rapidly

[01:28:52] <furrywolf> not lately. I tried it a few years ago and found it useless.
[01:29:25] <Tom_itx> zeeshan you need a worm gear in there too
[01:29:38] <The_Ball> furrywolf, yeah I can believe that, give it another spin now
[01:30:25] <zeeshan> Tom_itx: haha
[01:31:26] -!- adb has quit [Remote host closed the connection]
[01:31:58] <furrywolf> no debian package? never a good sign...
[01:32:40] <The_Ball> furrywolf, you sure, did you check for a download or in apt?
[01:32:46] <mttr> any one good at rhino cad
[01:33:06] <furrywolf> just checked their website, I have to add testing or unstable to get it.
[01:33:32] <The_Ball> Hm ok, it's in Ubuntu's default repos and Fedoras

[01:40:59] <furrywolf> installing freecad requires a larger download than I can do on this connection.
[01:41:59] <furrywolf> I'll have to wait until I can bring my laptop somewhere with wifi.
[01:42:35] <furrywolf> freecad itself isn't huge, but it depends on a fuckload of python crap apparantly.

[03:31:34] <furrywolf> ... why does a navigation menu need an entire screen instead of, say, two lines?
[03:31:49] <zeeshan> cause thats how i want it to be :D
[03:32:13] <furrywolf> it also blinks in a most annoying fashion when hovering over different links
[03:32:15] -!- g_mouer [g_mouer!~g_mouer@97-82-200-92.dhcp.hckr.nc.charter.com] has joined #linuxcnc
[03:32:20] <zeeshan> i noticed that
[03:32:22] <zeeshan> i wonder wh y
[03:32:26] <zeeshan> it goes away after you go over all of them
[03:32:47] <furrywolf> no, it doesn't.
[03:32:51] <zeeshan> for me it does :P
[03:33:16] <Connor> Works fine for me in Chrome.
[03:33:51] <Connor> okay.. it did it in FF..
[03:34:02] <Connor> are you overlaying the whole picture for each one?
[03:34:05] <furrywolf> my guess is it's because you used javascript crap instead of css hovers.
[03:34:12] <zeeshan> connor yes
[03:34:27] <Connor> That's why.. you need to pre-fetch those images.
[03:34:32] <furrywolf> yes, he is.
[03:34:38] <zeeshan> its preloading them
[03:34:43] <furrywolf> and it's not just prefetching, because it continues to flicker even after they're loaded.
[03:34:44] <zeeshan> im using dreamwaeaver
[03:35:04] <zeeshan> ill try to use css
[03:35:28] <Connor> After you hover over one.. it stops doing it..
[03:35:32] <furrywolf> it's also painfully fucking slow to load.
[03:35:48] <zeeshan> furrywolf: stop using a shitty connection :)
[03:36:04] <zeeshan> its 2014
[03:36:08] <furrywolf> let's load 1.4MB just to show 8 links!
[03:36:08] <zeeshan> almost everyone has cable internet or dsl
[03:36:21] <Connor> Language guys...
[03:36:38] <furrywolf> yes, I'm so glad no one you know uses a tablet or smartphone.
[03:36:51] <zeeshan> not meant to be a mobile site
[03:36:58] -!- uberadminer [uberadminer!~textual@unaffiliated/uberadminer] has joined #linuxcnc
[03:36:58] <zeeshan> its going to be content heavy
[03:37:03] <zeeshan> full of images
[03:37:20] <furrywolf> it's also wider than my screen, and 1024x768 isn't that odd...
[03:37:25] <zeeshan> so if 1.4mb of images causes issues
[03:37:37] <zeeshan> time to move on :P
[03:37:51] <zeeshan> furrywolf: are you from usa?
[03:37:55] -!- nofxx_ has quit [Ping timeout: 255 seconds]
[03:38:05] <zeeshan> that is worse than 720 P!
[03:38:29] <furrywolf> ... also, your 404 page is evil. but, that's probably your host's fault, not yours.
[03:39:07] <furrywolf> computer screens should not be measured by television sizes. computer screens do useful things, and displaying television is not a useful task.
[03:39:14] <zeeshan> yea
[03:39:22] <zeeshan> a computer screen should also not be 1024x768
[03:39:23] <zeeshan> lol
[03:39:27] -!- g_mouer has quit []
[03:39:34] <zeeshan> that's painfully crap
[03:39:43] -!- kramdradoow has quit [Quit: Leaving]
[03:39:45] <Connor> I often have mine at that size. the browser window that is.. not the monitor.
[03:39:48] <zeeshan> at minimum you need 1680x1050
[03:40:11] <zeeshan> i personally cant stand anything below 1920 x 1200

[03:41:14] <zeeshan> cad / coding etc
[03:41:33] <furrywolf> ... I think I fit 140 columns or something on this screen while coding. :P

[03:43:21] <furrywolf> 170 columns
[03:43:33] <Tom_itx> zeeshan, not sure i like that
[03:43:40] <Tom_itx> too much for just a menu
[03:43:48] <zeeshan> Tom_itx: its the banner page
[03:43:50] <furrywolf> 57 rows
[03:43:50] <zeeshan> i like it

[03:43:59] -!- nofxx_ [nofxx_!~nofxx@unaffiliated/nofxx] has joined #linuxcnc
[03:44:00] <Tom_itx> too much resources
[03:44:03] <zeeshan> the content page will be less fancier
[03:44:09] <furrywolf> banner pages are worse than useless.

[03:44:34] <furrywolf> "fancy" isn't a word I'd apply to it. all you need to do is make it blink and it can be 1999 all over again!

[03:45:14] <zeeshan> its a personal blog
[03:45:21] <Tom_itx> to each his own
[03:45:27] <zeeshan> i don't expect 1000s of hits
[03:45:27] <Tom_itx> but you somewhat asked...
[03:45:34] <furrywolf> zeeshan: I find displaying 57 rows of 170 characters to be adequate for coding.

[03:46:08] <zeeshan> :P
[03:46:19] <Connor> zeeshan: Sure, pay me!
[03:46:21] <zeeshan> haha
[03:46:42] <furrywolf> connor: http://fw.bushytails.net/css/imgwidget/imgtest.php I think is my favorite of my abuses-of-CSS.
[03:46:47] <Connor> oh. and I charge like 1.5x rate for friends and people who know me.. :)
[03:47:03] <zeeshan> well this is a start

[05:51:37] <zeeshan> http://fw.bushytails.net/css/gears/gearoutline01.png
[05:52:03] <zeeshan> can i use your code?
[05:52:15] <zeeshan> ill need to modify it for my color scheme
[05:52:43] <furrywolf> I'm far more proud of my randomly generating a different menu every time you load the page, complete with carefully shaping it, and making sure only gears turning opposite directions are allowed to edge up to each other, to make sure the geartrain isn't locked. :P
[05:53:14] <zeeshan> furrywolf: wow
[05:53:16] <zeeshan> i just noticed that
[05:53:19] <zeeshan> That is cool!
[05:53:35] <furrywolf> also, quick? that took me way way longer than it should have. I'm rusty.
[05:53:58] <zeeshan> i honestly havent touched html since i was 14
[05:54:03] <zeeshan> i used to do web design back then
[05:54:04] <zeeshan> basic stuff.
[05:54:07] <zeeshan> totally forgot it all
[05:54:40] <furrywolf> I need to add code to set the rotation of the gears correctly... right now they don't mesh properly.
[05:55:33] <furrywolf> the math needed to make the teeth line up is more than I'm in the mood for. getting past bedtime.

[06:21:26] <Connor> zeeshan: Do you have a 4th and 5th axis already ?
[06:21:41] <zeeshan> no
[06:21:56] <Connor> So, your just gonna hope those drivers you have will work? :)
[06:22:03] <zeeshan> already tested em
[06:22:20] <Connor> I mean, work for the 4th and 5th axis servo's.. which you don't have...
[06:22:32] <zeeshan> theyre oversized
[06:22:38] <zeeshan> for 1.5kW servos
[06:22:43] <zeeshan> i think they should be ok
[06:23:11] <Connor> What are those 3 funky rings on the mill head? behind the enclosure now...
[06:23:59] <zeeshan> they are the speed selectors
[06:24:07] <zeeshan> there are motors that go on there
[06:24:19] <Connor> okay.
[06:24:21] <zeeshan> to choose speeds :D
[06:24:31] <Connor> To change gears..
[06:24:51] <Connor> You going to bother... or just set it to a medium gear and use the VFD ?
[06:25:05] <zeeshan> i was initially going to make them work
[06:25:11] <zeeshan> but after i burned that speed selector board..
[06:25:19] <zeeshan> i think im just going to put it on a medium gear, vfd it up
[06:25:29] <zeeshan> and if i need the back gear, manually change it
[06:25:38] <zeeshan> its a vector vfd
[06:25:52] <Connor> Yea. So, it didn't use a VFD ?
[06:25:58] <zeeshan> so it should be able to produce high torque at low rpm
[06:26:01] <zeeshan> 1hz
[06:26:15] <zeeshan> i notice the non vector ones are useless below 10-12hz
[06:26:29] <zeeshan> you can stop the spindle with your hand
[06:26:36] <zeeshan> Connor: yes, no vfd
[06:27:15] <Connor> Do you know what you burned up on the gear selector board ?
[06:27:34] <zeeshan> definitely some logic gate ic
[06:27:48] <zeeshan> cause it operates to the point where its instant burn if i touch it
[06:27:48] <zeeshan> haha
[06:27:50] <Connor> it through hole or smd ?
[06:27:53] <zeeshan> thru hole
[06:27:59] <zeeshan> whole board is thru hole
[06:28:09] <Connor> You might see about just replacing the IC's on it.
[06:28:13] <Connor> shouldn't be that hard.
[06:29:27] <zeeshan> dude im just excited
[06:29:33] <zeeshan> cause i can start hooking up all the devices
[06:29:40] <Connor> Of course now you might not have enough clearance to mount the motors with the enclosure mounted..
[06:29:45] <zeeshan> no
[06:29:47] <zeeshan> i made sure there was enough
[06:29:49] <Connor> just don't go and blow anything up.
[06:30:03] <zeeshan> thats why im using those big ass spacers
[06:30:05] <zeeshan> the 6"
[06:30:57] <Connor> be careful when you screw the front panel on.. I see the wires running right under a screw hole on the upper enclosure.. left hand side.. middle
[06:31:00] -!- swingley has quit [Ping timeout: 250 seconds]
[06:31:07] <zeeshan> im only going to use
[06:31:09] <zeeshan> the 4 outer screws
[06:31:24] <zeeshan> and the middle two
[06:31:28] <Connor> That's the only one I see that looks like it might cause a issue
[06:31:45] <Connor> are they different brands? They look a little different..
[06:31:51] <zeeshan> the boxes?
[06:31:51] <zeeshan> yes
[06:31:55] <zeeshan> one is s crew panel
[06:31:56] <zeeshan> the other is a door
[06:32:02] <zeeshan> why i did that, is because thats all i had
[06:32:03] <zeeshan> :(
[06:32:47] <Connor> fans pulling are through enclosure or into it?
[06:32:53] <Connor> pulling AIR
[06:32:57] <zeeshan> pullers
[06:33:16] <Connor> no fans for the bottom eh?
[06:33:24] <zeeshan> will be on the door
[06:33:29] <Connor> ok
[06:33:37] <zeeshan> i couldnt find any good location for them
[06:33:39] <zeeshan> but the door
[06:33:39] <zeeshan> lol
[06:33:48] <zeeshan> itll just be a single fan
[06:33:53] <zeeshan> there shouldnt be much heat gen in there.
[06:34:00] <zeeshan> one 110v 25 watt fan
[06:34:11] <Connor> yea.. well.. the PC and PC PSU..
[06:35:06] <Connor> I see you got one of those 1" cable glands.
[06:35:18] <zeeshan> yessir
[06:35:22] <zeeshan> i have 2
[06:35:24] <zeeshan> one will be for the PC stuff
[06:35:31] <zeeshan> one is for things like encoder wires
[06:35:41] <Connor> only see one.
[06:35:45] <zeeshan> oh only one is mounted
[06:35:47] <zeeshan> the other is in my room
[06:35:54] <zeeshan> hey, im thinking..
[06:36:02] <zeeshan> for th is machine, i dont want the computer as part of the machine
[06:36:11] <zeeshan> by that i mean, i dont want the monitor mounted on the machine
[06:36:18] <Connor> ok
[06:36:25] <zeeshan> think a dvi extension cable, some usb extension cable
[06:36:34] <zeeshan> and a roller tool box with a plywood top
[06:36:35] <zeeshan> would be nice?
[06:37:00] <Connor> Probably wouldn't be to bad.
[06:37:26] <Connor> Mine has a 19" touch screen that is going to end up being a pendant style.
[06:37:32] <Connor> if and when I can get back to working on it.
[06:37:41] <Connor> Gotta pick up the RV this Saturday..
[06:37:46] <Connor> and wire it up to the house.
[06:38:24] <zeeshan> whatd you decide on powering it
[06:38:54] <zeeshan> fuck
[06:39:00] <Connor> gotta tap into my 220v circuit for the hot water heater in my shop and run a 6 gauge rubberized cable to it.
[06:39:02] <zeeshan> i just realized, how the hell will i power the monitor
[06:39:04] <zeeshan> :/
[06:39:14] <zeeshan> ill need a long ass cable that goes to the enclosure for pwoer
[06:39:15] <zeeshan> :/
[06:39:25] <zeeshan> Connor: ah.
[06:39:26] <Connor> Umm.. Just plug the monitor up "locally"
[06:40:08] <Connor> you can bundle the power cable with the video and usb too if needed.. so, just a extension cord..
[06:40:39] <zeeshan> i think i need to find some loom for it
[06:40:46] <zeeshan> i hate just relying on a pvc jacket
[06:40:58] <Connor> You probably want 4 USB cables.. 1 for Keyboard, 1 for mouse, 1 for USB stick and 1 for a Pendant if you get one of those like I have.
[06:41:08] <zeeshan> hmm
[06:41:11] <zeeshan> not a bad idea on the usb stick.
[06:42:26] <Connor> I have mine setup with a USB network adapter so I can pull stuff from my other computers..
[06:42:26] <zeeshan> interesting
[06:42:30] <zeeshan> max length is 16 feet for usb.
[06:42:33] <Connor> but, would rather have it wired with ethernet.
[06:42:34] <zeeshan> usb cables
[06:42:48] <zeeshan> i got a wireless card on this one
[06:43:09] <zeeshan> connor i think im just gonna do this:
[06:43:12] <zeeshan> 1 usb cable.
[06:43:17] <zeeshan> then a 3 port splitter at the end,.
[06:43:22] <zeeshan> it'll be cleaner
[06:43:35] <Connor> Yes, but less bandwidth.
[06:43:46] <Connor> and I would recommend dedicated one for the MPG
[06:43:47] <zeeshan> its just a kyboard and mouse :)
[06:44:01] <zeeshan> i might end up going with the wireless pendant
[06:44:02] <Connor> yes, but the MPG and USB Stick aren't
[06:44:12] <Connor> http://www.monoprice.com/Product?c_id=103&cp_id=10303&cs_id=1030312&p_id=6149&seq=1&format=2
[06:44:15] <zeeshan> but in reality, ill only be transferring small files
[06:44:43] <Connor> Active USB extension.. 32 Ft. :)
[06:44:47] <zeeshan> hehe
[06:45:09] <zeeshan> im gonna start hooking up all the device wiring tomorrow
[06:45:13] <Connor> Not exactly sure WHY would want the PC that far away from the machine...
[06:45:32] <zeeshan> i dunno, me standing and using that lathe comp
[06:45:36] <zeeshan> is really really annoying
[06:45:45] <zeeshan> im so used to sitting down and typing
[06:45:54] <Connor> I sit down at my mill.
[06:46:04] <Connor> of course.. the PC is right at the mill..
[06:46:47] <zeeshan> https://www.flickr.com/photos/128539016@N05/15497049023/in/photostream/
[06:46:49] <zeeshan> do you see that arm
[06:46:53] <zeeshan> with some ripped off wood?
[06:46:59] <zeeshan> and an aluminum spacer
[06:47:07] <zeeshan> i can mount my monitor there.
[06:47:08] <Connor> Yes
[06:47:12] <zeeshan> but i dont know where i will mount the keyboard and mouse
[06:47:22] <zeeshan> unless i should just get a touch screen..
[06:47:35] * zeeshan likes keyboard too much
[06:47:37] <Connor> could you not mount it below?
[06:47:44] <Connor> or is that right over the table ?
[06:47:52] <zeeshan> it can come past the table
[06:47:56] <zeeshan> but its very easy to move
[06:47:58] <zeeshan> the arm that is
[06:48:58] <zeeshan> mount the keyboard to the wall
[06:48:59] <zeeshan> :-)
[06:49:03] <Connor> looking for picture online...
[06:49:24] <Connor> with that arm.
[06:49:27] <Connor> what was the arm for ?
[06:50:00] <zeeshan> absolutely zero idea
[06:50:01] <zeeshan> haha
[06:50:14] <zeeshan> ive neever seen it used.
[06:50:18] <zeeshan> on any of the pics ive seen
[06:50:35] <zeeshan> http://www.resale.de/images/7906987_a_wf21.3.jpg
[06:50:38] <Connor> http://www.mullermachines.ch/MachineImages/Large/17162_3.jpg
[06:50:44] <zeeshan> yep
[06:50:47] <zeeshan> it just sits there..
[06:51:03] <Connor> looks like it might be used for something with the spindle maybe ?
[06:51:15] <zeeshan> no
[06:51:22] <Connor> or maybe a collet / tool holder rack ?
[06:51:25] <zeeshan> yea
[06:51:27] <zeeshan> that might be it!
[06:51:31] <zeeshan> a collet rack
[06:52:03] <Connor> It's not in a good position to use a a monitor or keyboard holder..
[06:52:12] <Connor> needs to be in front of the table..
[06:52:22] <zeeshan> it can extend out
[06:52:24] <zeeshan> lemme take a pic
[06:52:49] <Connor> yea.. but.. it's going to end up going right over the table I would think.
[06:52:49] <XXCoder1> you guys ever melted alum and made stuff?
[06:53:06] <Connor> Me? No. I would like to try casting some Alumn at some point.
[06:53:13] <XXCoder1> me too
[06:53:15] <Connor> http://www.mullermachines.ch/MachineImages/Large/17162_1.jpg
[06:53:22] <Connor> control is ideal location there..
[06:54:16] <zeeshan> https://www.flickr.com/photos/128539016@N05/15549651754/
[06:54:18] <zeeshan> i guess it doesnt.
[06:54:27] <zeeshan> its 3/4" of the way of the table
[06:54:32] <zeeshan> remember that table doesnt move in the y direction
[06:54:33] <zeeshan> the head does
[06:54:44] <Connor> right.. but it does in the X
[06:54:50] <Connor> https://www.youtube.com/watch?v=Hs5lYs71O-A
[06:55:45] <zeeshan> connor i was thinking of buying a tool chest to replace my two other toolboxes
[06:55:54] <zeeshan> but this one will be a nice one with a table top
[06:56:01] <zeeshan> might work better.
[06:56:23] <Connor> Dude, where do you get the money to do all of this with? :)
[06:56:28] <Connor> Oh wait.. your single..
[06:56:33] <zeeshan> im not single
[06:56:36] <zeeshan> well not married :P
[06:56:37] <zeeshan> but we live together
[06:56:45] <zeeshan> buy and sell stuff
[06:56:48] <zeeshan> school money
[06:56:56] <zeeshan> not much expense
[06:57:07] <zeeshan> and i dont buy clothes!
[06:57:17] <Connor> okay.. I'm headed back to the living room for a while then to bed.

[10:24:44] <Computer_Barf> I was interested in the kflop because of the feedback loops , particularly for liniar glass scales

[13:13:07] <Tom_itx> The thread angle is 60o. The thread depth is 0.614 x pitch.
[13:20:58] <archivist> depends if you want a form cutting insert or general purpose
[13:21:28] <The_Ball_Shed> I know next to nothing about cutting threads, so maybe general purpose
[13:22:00] <The_Ball_Shed> I can't imagine I'll cut anything but metric threads thought in the M3-M6 range
[13:24:32] <archivist> one sharp enough for m3 will easily do m6 as long as it is not a form tool that cuts the tip radius too, most cheap inserts dont do form

[17:03:26] <mozmck1> I'm talking about a real milling machine used..
[17:03:48] <malcom2073> Oh well... yeah. That's on my list of things to buy eventually, but I figure if I'm gonna spend a grand or two on a router, I might as well make it sturdy enough to do metal
[17:04:07] <malcom2073> since the price difference between 15mm rails and alumiunm frame and 35mm rails and steel frame is negligable

[17:05:42] <mozmck1> To make it rigid enough for steel like that thread will be an interesting chore. It also needs to be able to move very slow with lots of torque, while routing wood needs much faster speeds.

[17:30:17] <humble_sea_bass> I'm looking through the "open source" concrete lathe wiki
[17:30:35] <humble_sea_bass> those guys never really built this fucking thing
[17:33:55] <archivist> but they have a 3d model !
[17:34:16] <archivist> a photo realistic scam
[17:34:17] <humble_sea_bass> they have an excellent 3d studio max rendering too
[17:35:23] <SpeedEvil> I've wondered about vacuum cement mixing - for _really_ high aggregate fraction
[17:35:43] <humble_sea_bass> the insult lies in that Make: magazine wrote entire articles of this shit
[17:35:58] <SpeedEvil> normally, you need to be able to mix concrete - the particles have to be able to slide past eachother.
[17:36:24] <SpeedEvil> This sets a hard upper limit on the amount of solids you can have in the mix
[17:37:10] <SpeedEvil> If you have instead a low-pressure steam environment - you can mix without that being an issue
[17:37:35] <humble_sea_bass> I don't think vaccuum is what you want
[17:37:57] <humble_sea_bass> concrete needs oxygen
[17:38:02] <SpeedEvil> No, it doesn't.
[17:38:21] <humble_sea_bass> concrete? as in portland
[17:38:25] <SpeedEvil> It sets entirely through internal reaction- it does not need access to the air to dry
[17:38:53] <SpeedEvil> It sets perfectly fine - and as rapidly - if it's covered in plastic
[17:40:29] <humble_sea_bass> covered in plastic is not the same as a vaccuum
[17:40:53] <SpeedEvil> I do not mean to set it under low pressure. merely to mix it.
[17:40:59] <humble_sea_bass> I could be completely wrong, as the only concrete work I've done in my life is block work and foundations etc
[17:41:29] <SpeedEvil> I've actualy read long technical screeds on exactly how concrete sets chemically.
[17:41:40] <SpeedEvil> it's a really fun process - but doesn't involve anything moving into or out of the concrete
[17:41:51] <humble_sea_bass> yeah. exothermic reachtions etc etc
[17:43:00] <humble_sea_bass> you said vaccuum at the beginning, and that seems unnecessary for compaction. concrete vibration can handle that or just using shot-crete
[17:43:00] <humble_sea_bass> which is the most fun thing ever
[17:43:18] <SpeedEvil> I don't mean normal compaction.
[17:43:56] <SpeedEvil> If you take sand, and pack it down, there is a certain fraction of void space left.

[17:44:02] <XXCoder1> Jymmm: yes if its lots lumens type. that video it wasnt :)
[17:44:04] <humble_sea_bass> correct
[17:44:17] <SpeedEvil> You can't quite get to that with normal concrete - because the grains need to be able to move over each other while mixing - so does the aggregate
[17:44:34] <SpeedEvil> If you just try forcing it - you're going to get a lot of entrained air
[17:44:47] <humble_sea_bass> hence the vibrator
[17:44:56] <SpeedEvil> But if you do it under vacuum, you could in principle get a very low void fraction indeed.
[17:45:18] <humble_sea_bass> you'd need a bananas vacuum to pull entrained bubbles from a high aggregate slurry
[17:45:28] <SpeedEvil> (where 'vacuum' is really steam at 1PSI
[17:45:34] <SpeedEvil> yes - I mean entirely avoid the bubbles.
[17:45:41] <SpeedEvil> You start mixing under vacuum
[17:45:53] <SpeedEvil> The atmosphere is at all times steam.
[17:46:01] <SpeedEvil> With no air.
[17:46:17] <SpeedEvil> (until it's mixed, anyway
[17:46:23] <CaptHindsight> aka hot water
[17:47:08] <SpeedEvil> Well - you could in principle do the same at 120C
[17:47:12] <SpeedEvil> but concrete sets rather too rapidly then
[17:48:58] <CaptHindsight> http://www.cnc-arena.com/en/forum/epoxy-granite-machine-bases-polymer-concrete-frame--30155-405.html this thread already covers this approach
[17:49:07] <humble_sea_bass> well, for all this trouble, what is the aimed void fraction

[17:50:53] <humble_sea_bass> i don't think it gets better than shotcrete
[17:51:09] <CaptHindsight> you can control the cure time of epoxy by controlling the temperature
[17:51:53] <CaptHindsight> it's not as dramatic with concrete
[17:51:59] <SpeedEvil> CaptHindsight: It is, actually
[17:52:10] <SpeedEvil> i've done casting in the oven at ~80C
[17:52:13] <SpeedEvil> Goes quite fast
[17:52:19] <humble_sea_bass> Cap, but I think SpeedEvil has applications in mind where epoxy may not be optimal
[17:52:30] <SpeedEvil> humble_sea_bass: Or simply not as cheap
[17:52:42] <SpeedEvil> A 25kg back of epoxy is not $7
[17:53:54] <SpeedEvil> part of the interest in controlled void fraction is if you can use granite, and granite sand, and granite hardcore, and can get the void fraction in concrete really low - you basically have - pretty much - a slab of granite

[17:56:56] <SpeedEvil> CaptHindsight: well - yes - that's a major difference. Modulus should be fairly similar - up until it yields

[18:16:04] <zeeshan> hi guys
[18:16:17] <zeeshan> i have this parting blade
[18:16:22] <zeeshan> i think someone machined the top and bottom of it flat.
[18:16:27] <zeeshan> and down to 25 mm...
[18:16:32] <zeeshan> what kind of holder does it go in?

[18:17:16] <CaptHindsight> they ruined this?
[18:17:20] <zeeshan> looks like it
[18:18:28] <CaptHindsight> drill 2 holes and bolt it? :0
[18:18:58] <zeeshan> better yet, whats a good indexable parting blade that can fit in a BXA tool holder

[18:22:56] <CaptHindsight> the kits at Home Depot are
[18:23:41] <CaptHindsight> I've only seen some quotes on factory floors, looks like 10-20% actual materials cost

[18:28:47] <CaptHindsight> anything under a 55gal drum (~220Kg) I get upcharged anywhere from $3-10/lb
[18:29:29] <CaptHindsight> for resins and components
[18:29:44] <humble_sea_bass> *business opportunity*
[18:29:48] <humble_sea_bass> sell him a gallon
[18:30:23] <XXCoder1> lol
[18:30:28] <CaptHindsight> a 5 gallon UN approved bucket is ~$18
[18:30:40] <XXCoder1> actually thats not bad
[18:30:47] <humble_sea_bass> not from us composites
[18:30:50] <CaptHindsight> shipping a 5 gallon pail is ~$50
[18:30:58] <humble_sea_bass> http://www.uscomposites.com/polyesters.html
[18:31:00] <tjtr33> the rustoleum epoxy worked fine in garage ( 2yrs now ) but Rustoleum 'latex epoxy' wont stand up to sneaker traffic
[18:31:02] <CaptHindsight> empty bucket
[18:32:00] <CaptHindsight> so you're at ~$70 for shipping and an empty bucket + $80 for the epoxy
[18:32:23] <XXCoder1> yeah probably better to buy local

[18:35:38] <CaptHindsight> the US Composites 404 resin isn't bad for $160/5 gal
[18:36:01] <XXCoder1> shipped?
[18:36:09] <CaptHindsight> for $20 more I'd use the vinyl ester
[18:36:13] <tjtr33> mcmaster? lotsa epoxy choices
[18:36:35] <humble_sea_bass> mcmaster is like a loan shark
[18:36:45] <humble_sea_bass> everything costs 4-10 times more
[18:37:25] <CaptHindsight> I make similar types of resin but the small sales are a pain. $40/gal or resin and they want $500 in free tech support
[18:37:26] <tjtr33> yes, but convenient
[18:38:32] <CaptHindsight> XXCoder1: + shipping and they are east coast
[18:38:49] <XXCoder1> yeah not buying that aytime soon :) but thanks

[18:40:39] <CaptHindsight> Home Depot polyester resin is ~$36/gal (8lbs)
[18:41:29] <CaptHindsight> not bad considering $8 in unsaturated polyester, the can and shipping
[18:41:59] <tjtr33> part number? ( i got a 8" black pipe to coat )
[18:42:24] <XXCoder1> yeah ironically still cheaper due to no shipping

[18:49:23] <moorbo> isn't armour cable usually used for mains
[18:50:09] <humble_sea_bass> your choices ought to be rigid conduit

[18:50:20] <humble_sea_bass> or bx or armour cable

[19:12:57] <bobo_> no I mean the ground wire size

[19:13:13] <zeeshan> i'd like to keep the ground 3 awg too yes.
[19:13:54] <bobo_> makes sence to me also
[19:14:15] <zeeshan> im slapping myself for not buying this teck cable i found a little while ago
[19:14:18] <zeeshan> guy had 60 feet of it for $150
[19:14:26] <zeeshan> instead of metal conduit, i could have run that
[19:14:32] <zeeshan> but metal conduit looks cleaner...
[19:15:55] <Connor> I would use that liquid tight cable.
[19:16:07] <Connor> used for hot tubs and what not..
[19:16:15] <zeeshan> connor yes
[19:16:20] <zeeshan> its pretty much teck cable.
[19:16:29] <zeeshan> teck cable just has the wires through it already

[19:18:39] <zeeshan> for 50 feet.
[19:18:48] <Connor> That's what *I* Would use.
[19:20:01] <bobo_> I like Connor s idea
[19:21:43] <zeeshan> okay so 1-1/4" metal conduit from panel to disconnect
[19:21:49] <zeeshan> flexible conduit from disconnect to machine
[19:21:53] <zeeshan> this is gonna cost a lot :P
[19:22:03] <Connor> What gauge wire you using ?

[20:02:15] <zeeshan> furrywolf: yes
[20:02:18] <zeeshan> its awesome :)
[20:02:27] <zeeshan> im pretty impressed how quickly you put that code together
[20:02:37] <furrywolf> http://fw.bushytails.net/css/gears/imgmenu3.php is the animated one...
[20:02:57] <furrywolf> quickly? it took WAY too long. I've mostly been coding in C lately, my php and css were very rusty.
[20:03:27] <zeeshan> hell of a lot faster than it took me.
[20:04:11] <furrywolf> I spent way too much time making the gear teeth properly synchronized...
[20:05:15] <zeeshan> :D

[20:07:14] <furrywolf> malcom: yes. you're not allowed to use it for an actual site. :P
[20:07:31] <zeeshan> so basically: l1 = 26.9+5.4+0.6+2.5+5+0.7+3.2+1.1+12+12 = 69.4A l2 = 26.9+5.4+15+12+12 = 71.3A
[20:07:52] <zeeshan> 71.3 * 1.25 safety = 89A..

[20:14:40] <furrywolf> the animation isn't anything extremely complicated... it's just an animated GIF. heh.
[20:19:39] <bobo_> zeeshan the amp/wire size you have come up with seems useable (to me) the NEC code (to me ) takes in many factors of what can go wrong will go wrong and also go wrong as time goes on.
[20:20:06] <zeeshan> it looks like i can get away with 4awg
[20:20:43] <furrywolf> I just slowed the animation down. it's significantly less annoying now.
[20:23:00] <zeeshan> furrywolf: howd you make the rotating gif
[20:23:55] <furrywolf> brb
[20:24:53] <bobo_> temp rating rating of insulation is one of the main parts and I like equal size earth=ground wire
[20:31:59] <furrywolf> normally I'd use gimp's animation feature, but the version/options I have on this laptop seems to lack it, so I just duplicated the layer and rotated a few times.
[20:32:37] <zeeshan> ah cool
[20:35:12] <furrywolf> I just updated it so they're actually links you can click. :P

[20:35:40] <zeeshan> youre having too much fun
[20:36:17] <furrywolf> of course, lacking actual pages, they just link to google.
[20:36:50] <zeeshan> does anyone know how people come up with the electrical rating of an electrical device
[20:36:55] <zeeshan> if its just a simple motor, its easy..
[20:37:11] <zeeshan> but when you have a combination of multiple motors, power supplies, drives, control electronics
[20:37:32] <zeeshan> do you just add them, and then go up to the next nominal size?
[20:37:39] <zeeshan> like in my case 71.3 A -> 80A ?
[20:38:09] <furrywolf> that works, or run it and monitor the current.
[20:38:19] <zeeshan> or you just state 71.3A , and then people know they need to protect it using 4awg wire rated w/ an 80 A breaker
[20:38:40] <zeeshan> furrywolf: thats true, but might be hard to simulate worst case scenario :P

[20:39:14] <furrywolf> the trickiest part of the animation is making half them run the opposite direction... you can't just use two images, as they won't synchronize... so I used css3's transform functions to mirror the same animation, making it turn backwards.
[20:40:00] <furrywolf> nec tells you to use the next commercially available size breaker... so if you rate it at 72A, nec says to use an 80A breaker. your design should make sure it doesn't become melty on an 80A breaker.

[21:08:26] <Connor> zeeshan: One thing you need to consider is.. is EVERYTHING going to be running flat out.. I.E. What's the chances your going to have the Spindle running full out STALLED, and the X and Y and Z full out stalled?
[21:08:41] <zeeshan> highly unlikely.
[21:08:44] -!- skunkworks has quit [Quit: Leaving]
[21:08:46] <Connor> exactly.
[21:08:57] <zeeshan> so maybe a 60A breaker might be ok.
[21:09:00] <Connor> so, you can use smaller wire and smaller breaker..
[21:09:18] <Connor> knowing that if you have too much, the breaker will save you.
[21:09:18] <zeeshan> its going to suck so much
[21:09:24] <zeeshan> if i have to rerun the wire
[21:09:24] <zeeshan> :(
[21:09:39] <Connor> Why are you going to have to rerun it ?
[21:09:46] <zeeshan> cause i'd have to pull the 6awg wire
[21:09:49] <zeeshan> and run 4awg.
[21:09:52] <zeeshan> or 3awg
[21:10:05] <Connor> Oh. What do you have? 6awg already ?
[21:10:13] <zeeshan> i have 6awg at home yes
[21:10:47] <zeeshan> im running a 1-1/4 conduit regardless of 6 awg of 3awg
[21:10:49] <zeeshan> *or
[21:10:54] <zeeshan> at least i wont have to re-run the conduit
[21:11:28] <Connor> Single 6gauge wire is good for 37amps for power transmission.
[21:11:37] <Connor> So, 3 Phase would be over 60amps.
[21:11:53] <zeeshan> 6awg for residential wiring assuming 40c ambient
[21:12:08] <zeeshan> is good for 68.25 A
[21:12:22] <Tom_L> i got a 60A on my 6awg
[21:12:24] <zeeshan> thats why its very common to see a 60A breaker protect that wire
[21:12:30] <Tom_L> 50 or 60... i forget
[21:12:37] <zeeshan> its 60 likely
[21:12:39] <Connor> http://www.powerstream.com/Wire_Size.htm

[21:13:19] <zeeshan> but nec 310.16 is better.

[21:13:33] <zeeshan> http://prototypemachining.ca/Articles/WireCapacityCharts.html
[21:13:39] <zeeshan> table 310.16 has no derating on it.
[21:13:59] <zeeshan> so 90degC wire, 6 awg, 75A..
[21:14:09] <zeeshan> 40c derating factor .91 gives you 68.25A
[21:14:16] <Connor> Depends on the distance of the wire too.
[21:14:21] <Connor> and insulation.
[21:15:27] <Tom_L> there's a 2.4v drop over 50ft with a 60A load 6awg
[21:15:30] <zeeshan> insulation = 90 deg c.
[21:15:45] <Tom_L> 2.03%
[21:15:54] <zeeshan> v drop for hv inside a house i'd think is pretty insignfiicant

[21:44:27] <Tom_itx> probably big enough to run your mill
[21:44:39] <zeeshan> but i do make sure to turn off the switch on the compressor before i turn off the breaker.

[21:53:06] <furrywolf> I have a battery charger that uses a breaker as a switch. I also have a plasma cutter that uses a breaker as a switch. I've seen plenty of other things with breakers as switches...
[21:53:38] <Connor> I'm not saying you can't use a breaker as a switch.
[21:53:48] <Connor> I'm saying your really not suppose to.
[21:53:59] <Jymmm> Connor: Why not?
[21:54:01] <furrywolf> one is made in usa, the other italy, neither is garbage...
[21:54:03] <Tom_itx> the frequency of use may be much less than an overhead light on a switch
[21:54:18] <furrywolf> lambda us-made power supplies often have breakers as switches...
[21:54:36] <Jymmm> I've seen whole sets of lights wired directly to the breaker, there is no on/off switch.
[21:54:45] <Tom_itx> same here
[21:55:05] <furrywolf> same here. a place I was at once had all the lights in the entire building controlled from the breaker panel. old car dealership.
[21:56:00] <furrywolf> most impressive was the rollup door worked by a circuit breaker h-bridge. you had to turn on the right two to make it go up or down... the wrong two would both trip!
[21:56:58] <Jymmm> Ok, noe THAT needs a REAL switch

[21:56:58] <Jymmm> MOMintary
[21:57:10] <furrywolf> the wiring there was.... sketchy.

[21:58:35] <zeeshan> hahaha
[21:58:44] <zeeshan> with exposed contacts
[21:58:45] <zeeshan> i like it.
[21:58:56] <furrywolf> I'm not even sure how it was wired. it was all AC. I think one of them was turning on the main winding, and the other four switching how the start winding was wired.
[21:58:58] <Jymmm> Would need a resetable fuse, so you dont' burn out the motor at end of travle, lie a car window

[21:59:12] <furrywolf> I know if you turned on the wrong pairs, they'd instantly pop.
[21:59:40] <Jymmm> Yeah, had to be the opposite pairs.
[22:00:01] <furrywolf> the place had way, way, way too many breakers, since they worked everything in the building... many of them no one knew what they did... and no one knew how to make half the stuff in the building turn on either.
[22:00:02] <Jymmm> four breakers total iirc
[22:00:15] <furrywolf> we determined that if you turned one of them ON, the thrift store down the street lost power.
[22:00:23] <Jymmm> lol
[22:00:52] <furrywolf> lots of them could only be turned on one at time... i.e. you can have the outlets on one wall work, or the outlets on the other side of the wall work, but if you turned on both, you got neither.
[22:01:07] <Jymmm> thts kinda funny. If you turned it on, and lost power, did their lights turn back on?
[22:01:24] <furrywolf> it was a 3ft tall panel and two 2ft tall panels all wired together with a massive tangle of old cloth-insulated romex

[22:31:17] <CaptHindsight> I've heard of the interest that a sudden jump in power consumption raises. I wonder if it's just for electrical or if a jump in natural gas raises the same eyebrows
[22:32:11] <CaptHindsight> or 10 new windmills on the roof
[22:32:37] <unfy> my understanding is power
[22:32:40] <PCW> or a field of solar panels
[22:32:55] <furrywolf> they don't care how much power you use.
[22:33:08] <furrywolf> maybe elsewhere, but around here, growing is about as illegal as jaywalking.
[22:33:14] <unfy> ie: there was a story from vancouver or something where someone was running a mass bitcoin farm. they got raided with the fuckhead authorities looking for pot
[22:33:51] <furrywolf> you're about as likely to get caught, about as likely for them to care, and get about the same punishment.

[22:59:43] <furrywolf> bbl, working on the yard
[23:00:30] <mrsun> hmm anyone know how to get the whole size and shape for a hole that goes into the side of a cylinder ?
[23:00:34] <mrsun> right out at the dge
[23:00:35] <mrsun> edge
[23:01:04] <mrsun> http://woodgears.ca/dust_collector/cyclones.jpg like the one to the right
[23:01:08] <mrsun> or left ... :P
[23:04:23] <unfy> as in the shape of the cylinder as it intersects the circumference ?
[23:04:34] -!- Thetawaves [Thetawaves!~Thetawave@48-147-42-72.gci.net] has joined #linuxcnc
[23:04:52] <mrsun> i guess ... the tube that comes from the side ...
[23:05:11] <CaptHindsight> you want to know how to size it?
[23:05:30] <mrsun> yes as the hole will not be axactly round )
[23:05:31] <mrsun> =)
[23:05:53] <furrywolf> http://math.stackexchange.com/questions/628624/surface-area-of-intersection-of-two-cylinders do math like that. :P
[23:06:42] <furrywolf> a good cad program should be able to spit it out numerically
[23:06:52] <CaptHindsight> mrsun: or do you want to know how to actually make the hole? and yes^^
[23:07:17] <mrsun> i want to know how to make the hole ...
[23:07:25] <unfy> for me, it'd just be draw both the chamber and then a full cylinder, then occlude the chamber after inserting the cylinder
[23:07:25] <mrsun> so i can fit a pipe in like that
[23:08:01] <CaptHindsight> mrsun: what are you making the cyclone from? sheet metal?
[23:08:07] <mrsun> yes
[23:09:05] <furrywolf> mrsun: cut a 45 degree angle on a piece of pipe. hold it against the cylinder in desired position. use a flat/straight pencil to trace around the pipe, using the length of the pencil to project onto the surface. cut out with torch/nibbler/whatever. stick pipe through hole. trace around pipe. torch/etc pipe.
[23:09:08] <furrywolf> no math needed. :)
[23:09:14] <CaptHindsight> mrsun: can you cut the opening while the sheet metal is still flat?
[23:09:34] <mrsun> no .. its already welded :P
[23:09:37] <_methods> you have to lay it out
[23:09:58] <furrywolf> the method I just gave is pretty easy.
[23:10:10] <mrsun> furrywolf: i guess =)
[23:10:14] <furrywolf> bbl
[23:10:29] <zeeshan> mrsun: can you clarify
[23:10:38] <zeeshan> you're trying to make a hole in the cyclone dust collector
[23:10:39] <zeeshan> ?
[23:10:43] <zeeshan> the left port?
[23:10:56] <mrsun> the port that comes in from the side yes
[23:11:02] <mrsun> a round hole in a flat surface isnt hard
[23:11:18] <zeeshan> and you said it's all welded together right now
[23:11:19] -!- Thetawaves has quit [Quit: This computer has gone to sleep]
[23:11:23] <zeeshan> so you're gonna use like a hole saw?
[23:11:30] <mrsun> no
[23:11:42] <CaptHindsight> mrsun: can you cut the port tube to the radius of the welded part?
[23:12:03] <zeeshan> mrsun: shears?
[23:12:13] <mrsun> zeeshan: doesnt realy mater WHAT i cut it with
[23:12:15] <zeeshan> i have done something like this before
[23:12:21] <_methods> are you going round into round?
[23:12:21] <zeeshan> but it all depends on how you're gonan cut it.
[23:12:25] <mrsun> question was HOW to get the hole shape
[23:12:27] <mrsun> =)
[23:12:31] <zeeshan> thats easy.
[23:12:33] <zeeshan> take a piece of paper
[23:12:36] <zeeshan> draw a circle of the diameter of the tube
[23:12:41] <CaptHindsight> there are few ways
[23:12:42] <zeeshan> wrap it to the outer cylinder.
[23:12:50] <zeeshan> trace the projection onto the cylinder.
[23:12:51] <zeeshan> done
[23:12:54] <mrsun> ehm...
[23:13:24] <mrsun> that wouldnt work :P
[23:13:28] <zeeshan> why
[23:13:45] <furrywolf> because it's the wrong shape. lol
[23:13:47] <_methods> is it round to round? or round to a cone?
[23:13:50] <zeeshan> haha
[23:13:56] <zeeshan> it works on my head :(
[23:13:57] <mrsun> round to round .. from the freakin side!
[23:14:02] <mrsun> how hard is it .. ive shown pictures! :P
[23:14:04] <_methods> on center?
[23:14:08] <zeeshan> no
[23:14:09] <_methods> or offset
[23:14:11] <zeeshan> its offset
[23:14:11] <furrywolf> it's round to round. but the intersection curve is a funky ellipsoid, not round.
[23:14:13] <zeeshan> he has pics man
[23:14:14] <zeeshan> lol
[23:14:25] <_methods> yes
[23:14:27] <mrsun> http://woodgears.ca/dust_collector/cyclones.jpg the port comming from the SIDES of the cyclone and thein baffle in that picture .. is what i want to cut out
[23:14:28] <zeeshan> mrsun: dont have cad?
[23:14:47] <furrywolf> manually projecting the curve is the easiest way. tack it together and use a straightedge if you have to.
[23:14:55] <_methods> i can lay it out for you
[23:15:10] <_methods> but i need to know the diameters and where you want to intersect
[23:15:10] <mrsun> zeeshan: well .. i can cut parts in cad programs i have yes .. but i cant that i know of make that part flat then so i can cut the shape from a paper then trace to the sheet metal
[23:15:17] <CaptHindsight> shine bright light down the tube, trace around the edge of light/dark
[23:15:38] <_methods> mrsun: that is the way to do it
[23:15:39] <zeeshan> mrsun: you use flat pattern
[23:15:44] <zeeshan> using sheet metal module

[23:16:13] <mrsun> "sheet metal module" ?
[23:16:13] <zeeshan> lemme show u a pic.
[23:16:25] * furrywolf would have had it cut by now, by using simple and stupid methods, but actually doing it. :P

[23:16:46] <mrsun> _methods: i do not have the numbers in my head now and im laying in bed ...
[23:17:05] <_methods> ok well let me know and i'll develop the patterns for you
[23:17:13] <CaptHindsight> use a laser with the same diameter as the tube, blast away :)
[23:17:41] <zeeshan> i was wrong with my paper circle thing earlier
[23:17:44] <CaptHindsight> get s9omeone here to CAD it for you and post a pdf template
[23:17:44] <zeeshan> you gotta cut the circle first
[23:17:46] <zeeshan> and project light lol
[23:18:16] <furrywolf> ... a straight edge is all you need for this project, or if it's small, just a flat pencil.
[23:18:30] <_methods> furrywolf: yes your method will work just fine
[23:18:32] <zeeshan> mrsun: this is what i mean.

[23:54:32] <zeeshan> enough of this!
