[00:00:05] <renesis> he doesnt like the business, you just said
[00:01:00] <furrywolf> he likes the business. he'd just like it a whole lot more if good live bands paid the bills, not idiots with laptops.
[00:01:32] <furrywolf> if you're not familiar with jwz, he's a bit of a character. you're probably not old enough to remember netscape 1.0 and who wrote it... lol
[00:01:46] <renesis> id like it more if the live bands sounded like idiots with the laptops
[00:01:57] <renesis> sometimes tells me the owner wouldn't
[00:02:22] <renesis> yeah i remember when nthe internet sucked
[00:02:25] <renesis> i has a SNES
[00:02:30] <renesis> my friend had playstation
[00:02:45] <renesis> ^s
[00:03:06] * furrywolf didn't have any game hardware, preferring to be useful
[00:03:09] <renesis> seriously everyone had playstation, i knew like two guys played pc games
[00:04:19] <furrywolf> I've never seen the point of gaming. completely uninteresting use of time.
[00:04:30] <renesis> its harder for live bands to do a show like a performance mixed dj set
[00:04:41] <renesis> live bands stop and take a break every 3 or 4 minutes
[00:05:44] <renesis> like, mixed set is usually 30 minutes minimum, average between 60 and 90 minutes of continuous music, and sometimes are handed off without break to form like 4-6 hours of continuous music
[00:06:17] <renesis> that doesnt happen at a rock show, and doing electronic music live is awesome but the performers look pretty dead after an hour
[00:06:22] <furrywolf> except it's all music you've already heard, there's nothing interesting happening on stage, and invariably the guy playing it is a fucking idiot who blathers.
[00:06:35] <renesis> um
[00:06:38] <renesis> same with live bands
[00:06:51] <renesis> and no, performance mix stuff usually includes unreleased stuff
[00:07:02] <renesis> and the whole point is to mix tracks into something new
[00:07:42] <renesis> like, sometimes two things on top of each other works out and its pretty fucking unexpected and feels amazing (remember is a tactile form of music)
[00:10:11] <furrywolf> there has never been a time when I've felt a DJ improved music, and there has never been a time when I felt a MC didn't ruin it.
[00:10:28] <renesis> well youve prob just been to house shows
[00:10:47] <renesis> i kind of feel embarassed to be at those shows
[00:11:26] <furrywolf> I've never been to one in person. lol
[00:11:42] <renesis> then you cant speak on it, the whole point is being there
[00:11:45] <furrywolf> 1) there's no music here other than bars, and 2) I wouldn't go to one even if there were.
[00:12:01] <renesis> bass music at small vanues is awesome
[00:12:17] <furrywolf> this area is remarkably devoid of good music. occasionally a band will play at the university. the music shows are all reggae, hiphop, etc.
[00:12:52] <renesis> well move out of the sticks
[00:13:22] <furrywolf> there's a very large reggae show, best known for its cosumption of ludicrous quantities of drugs, bad music, violence, racist performers, and management not paying workers.
[00:13:35] <furrywolf> consumption
[00:13:58] <furrywolf> it gets cancelled every other year or so because they piss the county off to the point they revoke their permits
[00:13:58] <renesis> reggae on the river?
[00:14:02] <renesis> i so want to go to that
[00:14:35] <renesis> will be like 800 miles away then =\
[00:14:42] <furrywolf> ... do you consider doing drugs a lifestyle?
[00:14:52] <furrywolf> because you have to if you want to enjoy any of the music.
[00:15:07] <renesis> i dont mind clouds of pot
[00:15:27] <furrywolf> how about coke and meth? :P
[00:15:39] <renesis> not into it
[00:15:50] <renesis> coke isnt so bad, meth is some freak show shit
[00:16:13] <renesis> but if youre going to be around musicians and media industry types, coke is going to happen
[00:16:13] <furrywolf> meth is very, very popular here.
[00:16:22] <renesis> coffee just isnt enough in that scene
[00:17:50] <renesis> also stoners and tweakers tend not to congregate, it doesnt really work well
[00:18:30] <renesis> my guess is most of the tweakers are poor and homless locals, and the festivals are 90% weed acid shrooms mdma and coke
[00:18:31] <furrywolf> lol
[00:18:41] <furrywolf> I see you've never been here.
[00:18:52] <renesis> never lived there
[00:19:07] <furrywolf> duude, we can be stoned ALL NIGHT without needing to sleep! it's like totally awesome!
[00:19:11] <renesis> but i imagine its like every city in california
[00:19:15] <renesis> tweakers everywhere
[00:19:18] <furrywolf> I haven't slept in six days!
[00:19:32] <renesis> right most stoners arent into that
[00:19:49] <renesis> you dont sustain that functionally for long in normal circumstances
[00:21:07] <furrywolf> tweekers have a different standard of functional. being able to break into a car, steal something, then take it into 700 separate pieces because you forgot you were going to sell it to the pawn shop, is normal functionality.
[00:21:37] <renesis> right im saying thats not most people, and not most stoners
[00:21:40] <renesis> thats a tweaker
[00:22:04] <furrywolf> yeah, there's not too much overlap... but there definitely is some. and raggae on the river attracts both.
[00:22:37] <renesis> theres overlap in everything, music festivals attract drug users
[00:23:07] <renesis> a reggae festival is going to be mostly psychadelics and weed, and most of those users are pretty hostile towards meth addicts
[00:24:25] <renesis> ravers would be a bit more accepting, but honestly most everyone considers tweakers pretty disgusting
[00:24:30] <furrywolf> I think you're vastly overestimating the usefulness of the people who attend it.
[00:25:22] <renesis> theyre useful in that they contributed to the party
[00:26:36] <renesis> you go, youre polite within the context of the event and enjoy yourself, you leave, who gives a fuck how much someone else contributes to what
[00:27:00] <renesis> they contributed money to the promoters pocket so he or she wants to do it again
[00:27:04] <furrywolf> it's not stoners sitting around listening to music while passing the bong. it's drunks, tweekers, and the worst of society getting together to get wasted, start fights, trash local businesses, destroy the propety, and generally demonstate their non-contribution to society.
[00:27:22] <renesis> sounds like a normal music festival
[00:27:31] <renesis> if it doesnt make the local area money, they should ban it
[00:27:40] <renesis> my guess is that it does, or they would have banned it
[00:28:01] <furrywolf> did I mention it randomly gets cancelled, has changed owners several times, and no one gets paid?
[00:28:19] <renesis> again, sounds like normal music festivals
[00:28:30] <furrywolf> it's lost money
[00:28:49] <renesis> i dont want to keep repeating myself, but...
[00:28:58] <furrywolf> local businesses hate it, because the people it attracts don't buy stuff - they just steal what they need and pick fights with employees.
[00:29:16] <renesis> so dont let the city approve the permits
[00:29:54] <furrywolf> you mean like "The 2010 festival was canceled due to the financial trouble of the organizer, Tom Dimmick, resulting in his denial of a Conditional Use Permit by the Humboldt County Planning Commission."
[00:30:03] <furrywolf> it's the county that denies the permits, not the city.
[00:30:20] <renesis> same deal
[00:30:49] <furrywolf> "The dispute centered on revenues, with the Mateel questioning why profits estimated by People Productions did not materialize, why there was a discrepancy between the number of tickets approved and reported attendance and $300,000 in cash expenditures with no receipts." lol
[00:31:29] <renesis> so normal music festival?
[00:31:49] <furrywolf> I think last year they made the organizers rent something like half the police force, to try to keep the violence down...
[00:32:01] <furrywolf> no. normal music festivals don't involve hard drugs and violence.
[00:33:40] <furrywolf> the original founders left because of the switch to hard drugs and bad music
[00:35:01] <renesis> what?
[00:35:12] <renesis> all music festivals involve hard drugs
[00:35:31] <zeeshan> renesis knows all about drugs
[00:35:34] <zeeshan> especially the psychotics
[00:35:37] * zeeshan hides
[00:35:47] <renesis> i know that theres people doing drugs at music festivals
[00:35:51] <renesis> and fights happen
[00:36:10] <renesis> its lame but thats why they pat you down on the way in
[00:36:51] <furrywolf> I really don't think you're getting what this event is. it's not stoners. it's more like what you'd expect at... I don't know what to compare it to. as far as I know, there has never been any other festival with such unpleasantness. it's like a skinhead meeting or something.
[00:38:05] <furrywolf> the performers they've been finding keep promoting racism and homophobia, to the point where they make the news by being banned from other local places.
[00:38:08] <renesis> like coachella, or lollapalooza, or that shit with all the new metal bands
[00:38:11] <renesis> family values
[00:38:23] <renesis> there was tons of drugs at dead shows
[00:38:36] <furrywolf> LOL. it is NOTHING like a dead show.
[00:38:41] <furrywolf> completely the wrong vibe.
[00:38:49] <renesis> there were hard drugs at dead shows
[00:38:57] <renesis> and a lot of people scamming people
[00:39:10] <renesis> and a lot of useless people, to use your word
[00:39:41] <furrywolf> deadheads are a completely different kind of useless
[00:40:07] <renesis> um, no
[00:40:28] <renesis> just because you like them doesnt suddenly make them more productive
[00:41:16] <renesis> electronic music festivals are from the rave scene which was an underground psychadelic drug scene
[00:41:21] <furrywolf> I don't like them. at all.
[00:41:52] <renesis> club scene is from disco and thats all about cocaine and designer drugs
[00:42:18] <furrywolf> why do you keep talking about psychedelics? dead shows are where you find psychedelics. not reggae on the river.
[00:42:27] <furrywolf> reggae on the river is coke and meth.
[00:42:35] <renesis> im sure theres tons of acid and shrooms there
[00:43:00] <renesis> the whole country is about coke and meth now =\
[00:43:44] <furrywolf> this county is more about meth than most. heh.
[00:43:51] <renesis> youre in a rural area, meth is going to be an issue
[00:44:43] <furrywolf> I've been in other rural areas. they're not nearly as bad as here.
[00:46:05] <renesis> because youre where stoners go to becomes homeless bums
[00:46:20] <renesis> its like how santa barbara is where surfers go to become homeless bums
[00:47:04] <furrywolf> the homeless here aren't stoners. they're all tweekers.
[00:47:22] <furrywolf> the hippies in school busses thing is long gone.
[00:47:26] <furrywolf> now it's all tweekers.
[00:47:31] <renesis> well right because they became homeless bums
[00:47:46] <renesis> homeless bums in santa barbara dont surf, they drink and tweak
[00:47:58] <furrywolf> ... no, because they got jobs, and became non-stoners, or they started doing meth, and became tweekers.
[00:48:26] <renesis> same deal, tweaker is the road to homeless bum
[00:48:42] <renesis> its more of a rural thing tho
[00:48:57] <furrywolf> I've never been to santa barbara, but I lived in santa cruz for a few years, and I can tell you the homeless there is COMPLETELY different than the homeless here.
[00:49:27] <renesis> yeah santa cruz is more expensive, kind of more remote, its nice
[00:49:52] <renesis> you live in stoner mecca
[00:50:03] <furrywolf> this area has a reputation for hippies, stoners, surfers, etc. that's all in the past. dead. gone.
[00:50:09] <furrywolf> now we have tweekers.
[00:50:26] <furrywolf> even the pot growers are tweekers. they're just here for the money, not the now-dead culture.
[00:50:47] <furrywolf> the pot growers shoot each other
[00:50:52] <renesis> you didnt keep it on the down low
[00:50:56] <furrywolf> we have a homicide rate substantially worse than oakland
[00:51:24] <furrywolf> the whole hippie-stoner-surfer thing is gone.
[00:52:26] <renesis> well considering how much shit you talk about stoners im not surprised they left
[00:52:48] <furrywolf> there's still some remnants of hippie stoner culture left, but the tweekers have mostly driven them out.
[00:52:56] <renesis> OR and WA coast is prob more your thing
[00:54:15] <renesis> like, your hippy culture was selling weed to the whole state and made it clear that laws were not well enforced there
[00:54:47] <renesis> like, im a kid in elementary school i know that humboldt is where all the weed comes from, how do you not expect professional growers to not move in?
[00:54:55] <furrywolf> the hippie growers have mostly been put out of business by the large-scale tweeker grows.
[00:55:19] <renesis> well, thats and legal growing in the rest of the state
[00:55:22] <renesis> for like 15 years now
[00:55:58] <renesis> so youre okay with the large scale mexican growers or its racist to talk about them?
[00:57:10] <furrywolf> the large scale mexican grows are a trival percentage of the grows, and just receive disproportionate media attention.
[00:57:26] <renesis> haha, very sjw of you
[00:57:26] <furrywolf> if they make half a percent of the output I'd be surprised.
[00:57:33] <furrywolf> sjw?
[00:57:37] <renesis> its gotta be the tweakers!
[00:57:43] <renesis> google
[00:58:32] <furrywolf> seems like it translates to troll.
[00:58:36] <renesis> seriously though, theyre probably mostly in trouble because the whole state grows weed local now
[00:59:01] <renesis> who wants some outdoor or greenhouse from up north you can get the same plus indoor local
[00:59:18] <furrywolf> there are mexican grows, but they cause a very small percentage of the problems. they just get printed in big headlines when they get busted, because they're unusual.
[00:59:28] <renesis> furrywolf: agressively politically correct, so yeah troll
[01:00:20] <renesis> anyway, if the problem is money, its because 15 years of widespread growing has reduced their market share
[01:00:44] <renesis> i mean its crazy how cheap weed is right now
[01:01:17] <renesis> you can even sell bulk dank weed unless you want to do like few dollars a gram
[01:01:31] <furrywolf> $1000/lb for decent stuff is what I've been hearing lately
[01:01:39] <renesis> like, if you got a weed farm youre in for some tough times
[01:01:42] <renesis> pfft
[01:01:53] <furrywolf> ... gram? we don't measure weed in grams here. lol
[01:02:13] <furrywolf> ounces are the smallest unit, and no metric. :P
[01:02:27] <furrywolf> grams is for meth
[01:02:29] <renesis> thats what it goes for retail, and theres not a lot of middlemen
[01:02:37] <furrywolf> and heroin
[01:03:05] <zeeshan> drugs are lame :p
[01:03:25] <renesis> so like, people are growing in the back of the shop, and selling at cheap gram rates, no bulk cuts in prices
[01:03:49] <renesis> like, weed farms hundreds of miles away really dont make a lot of sense
[01:04:10] <furrywolf> ... gram rates? again, weed is not sold in grams.
[01:04:24] <furrywolf> things sold in grams come from trailers that small like draino.
[01:04:45] <renesis> how much weed have you bought
[01:04:56] <furrywolf> smell
[01:04:58] <renesis> how many weed shops you been into?
[01:05:06] <furrywolf> people buy weed?
[01:05:22] <furrywolf> I have to tell people no, I don't want them to give me weed. lol
[01:05:33] <renesis> retail its sold in grams and 1/8s, and a fair 1/8 is 3.5g
[01:06:18] <furrywolf> there's 2 or 3 I think retail shops here, never been in any of them. the others went out of business. seems you can't sell weed.
[01:06:24] <renesis> like, theres lots of jokes about the miss .3g when you convert ounces to grams at the rate of 28q/oz
[01:06:42] <renesis> right where you live, where you are saying weed culture is dying
[01:06:50] <renesis> well, stoner grower culture
[01:06:53] <zeeshan> anyone around that isn't talking about lame drugs? :DP
[01:07:10] <furrywolf> zeeshan: I'd be happy to talk about anything else, but I need to get to bed soon.
[01:07:17] <furrywolf> no one here ever talks about strapons. :(
[01:07:23] <renesis> i can talk about tinsel wire some more
[01:07:40] <zeeshan> http://www.kijiji.ca/v-hand-tool/mississauga-peel-region/mitutoyo-holttest/1044808230?enableSearchNavigationFlag=true
[01:07:44] <zeeshan> was wondering what the heck these are
[01:07:54] <zeeshan> three point mics
[01:07:56] <zeeshan> i guess for bores?
[01:08:08] <renesis> outside micrometers?
[01:09:16] <renesis> HOLTEST sounds like a engrish part number heh
[01:10:06] <furrywolf> that's a lot of money.
[01:10:11] <zeeshan> thats what i was thinking lol
[01:10:16] <zeeshan> sounds a little overpriced!
[01:10:25] <furrywolf> you can get four pounds of indoor or six of outdoor for that.
[01:10:28] * furrywolf hides
[01:10:36] <zeeshan> lol
[01:10:40] <renesis> furrywolf: anyway to summarize, your weed farms are going out of business because they sell for $2/g instead of $5-20
[01:11:53] <renesis> but yeah tweakers suck
[01:14:25] <renesis> guys what color do you think the new mclaren is gonna be
[01:14:51] <zeeshan> blak
[01:15:34] <furrywolf> bbl, wolfy bedtime
[01:17:24] <renesis> zeeshan: maybe
[01:17:56] <renesis> they want to kill the chrome because its basically the same as the silver when they were a mercedes team
[01:18:30] <renesis> dennis mentioned something about grey, but keeps bringing up the dayglo red
[01:18:46] <renesis> marussia stole their red on white marlboro livery
[01:19:07] <renesis> and dennis says orange is going backwards
[01:19:55] <renesis> orange + kiwi logo would either be awesome or a disgrace depending how fast they get the honda pu sorted
[02:18:44] <Deejay> moin
[06:33:04] <renesis> https://twitter.com/McLarenF1/status/595906798252630016
[06:33:09] <renesis> zee was right
[06:33:31] <renesis> theyre like the red version of force india and lotus now
[09:06:10] <_methods> anyone in here ever try any cheap diamond grinding wheels from ebay?
[09:07:32] * archivist_herron is waiting for _methods report on them :)
[09:10:02] * jthornton used to use a lot of diamond grinding wheels
[09:18:31] <_methods> yeah i'll try one out to see how they work
[09:43:17] <_methods> not expecting too much for $50-60 lol
[09:43:28] <JT-Shop> /me needs to layout a 45 off of an arc to get the retaining wall right
[09:43:54] <_methods> draw line tangent to arc then draw perp line to tangent line
[09:44:10] <_methods> lazer beams
[09:45:35] <JT-Shop> I watched Roy Underhill do it last night with dividers but I don't think that works well in the dirt
[09:45:48] <_methods> strings baby
[09:45:51] <_methods> and stakes
[09:45:59] <JT-Shop> yep
[09:48:01] <_methods> bust out the plumb bobs and stakes hehe
[09:48:14] <_methods> lasers do make it much easier though
[09:54:35] <norias> lasers
[09:55:24] <norias> everyone life is made better by laser
[10:02:52] <_methods> pew pew
[10:12:49] <norias> everyone duck!
[10:12:52] <norias> lasers!
[10:12:53] <norias> er...
[10:13:08] <norias> how did "duck" ever come to mean
[10:13:27] <norias> 'move or bend to a lower position'
[10:13:28] <norias> ?
[10:13:45] <tiwake> possibly latin root words?
[10:14:39] <Rab> Because it rhymes with "you sucka"
[10:14:41] <norias> hmm
[10:15:01] <norias> i'm seeing that the whole 'move to a lower position'
[10:15:09] <norias> was the more original use
[10:15:27] <norias> that was then used to describe waterfowel
[10:16:55] <tiwake> ah
[10:17:12] <tiwake> norias: yeah, I just looked it up in my 1828 webster dictionary
[10:17:22] <norias> and?
[10:17:34] <tiwake> its described as the action ducks take to plunge the head underwater
[10:17:50] <tiwake> IE move out of the way
[10:18:09] <norias> as if there are lasers
[10:18:27] <tiwake> pretty sure lasers didnt exist in 1828 ;)
[10:18:41] <norias> are you sure?
[10:18:50] <tiwake> fairly
[10:19:32] <tiwake> (also, everyone should have an 1828 webster dictionary... its pretty fantastic)
[10:19:44] <norias> i bet
[10:20:01] <norias> is that the first year?
[10:20:23] <tiwake> the very first american english dictionary printed
[10:21:16] <norias> yeah, that's what i thought
[10:21:23] <CaptHindsight> rom Old English *ducan "to duck, dive"
[10:22:21] <norias> is yours a reprint?
[10:22:26] <CaptHindsight> http://english.stackexchange.com/questions/33420/etymology-of-duck
[10:22:35] <tiwake> yeah, mine is a reprint
[10:22:46] <norias> makes sense
[10:23:05] <tiwake> though I'm having a hard time finding a database version of it
[10:23:14] <norias> :(
[10:23:17] <tiwake> I want to plug into my spell checker
[10:23:21] <norias> i can't help but feel like
[10:23:23] <norias> sometimes
[10:23:35] <norias> that educated folks were better educated
[10:23:43] <norias> say in the 19th century
[10:23:55] <norias> but i have no support for that statement
[10:23:59] <norias> just a feeling
[10:24:16] <tiwake> its the public school system... enh.. I was homeschooled
[10:24:35] <norias> could be
[10:24:56] <tiwake> college is about as good as it was I think
[10:25:15] <norias> you think?
[10:25:26] <norias> i guess that depends on the college, too
[10:26:21] <JT-Shop> the cold war coined "duck and cover"
[10:26:51] <tiwake> there are more options... with public school its whatever is next to you. unless you count private and other schooling options (that most people seem to ignore?)
[10:27:45] <Rab> Because they're expensive.
[10:27:55] <norias> reading about the whole tesla home battery
[10:27:57] <tiwake> homeschooling isnt
[10:28:04] <norias> yes it is
[10:28:20] <norias> who did your homeschooling?
[10:28:33] <tiwake> my parents.. heh
[10:29:05] <tiwake> its pretty much the cheapest option
[10:29:13] <norias> so, during the day
[10:29:14] <tiwake> otherwise it would be private tutoring
[10:29:15] <Rab> I don't think it's feasible without a stay-at-home parent, although there's a lot more community homeschooling support around here than when I was a child.
[10:29:17] <norias> was someone home with you?
[10:29:30] <norias> i mean, that's my point
[10:29:41] <norias> think if i home schooled
[10:29:51] <norias> my children
[10:30:00] <norias> either my wife or i has to stay home to do that
[10:30:10] <norias> so we're -$50k a year
[10:30:24] <norias> that's expensive
[10:30:41] <tiwake> my parents have a small business on the property.. but yeah, not everyone can
[10:31:32] <tiwake> but still, IMO its the best option to maximize learning potential
[10:32:05] <norias> if... your parents are relatively smart
[10:32:20] <norias> not that public school teachers are
[10:32:23] <tiwake> well
[10:33:39] <norias> hmmm
[10:34:20] <norias> 400V in the tesla home battery
[10:34:42] <zeeshan> http://www.kijiji.ca/v-business-industrial/kitchener-waterloo/single-lip-bench-top-grinder/1069684577
[10:34:45] <zeeshan> is this an end mill grinder
[10:34:52] <tiwake> neither of my parents know (pretty much anything) about programming... one day I decided to learn how to and basically locked myself in my room for a week venturing only for food. came out knowing the basics in Java and they considered that part of my schooling :3
[10:35:04] <Rab> There are other issues with the public school system. My gfiend is a school teacher, she spends the school year drilling kids through a succession of inane standardized tests. Miserable and unproductive for everyone involved. I wouldn't submit a child to that.
[10:35:25] <zeeshan> rab those tests are so ez
[10:35:26] <zeeshan> lol
[10:35:30] <tiwake> zeeshan: endmill and drill
[10:36:06] <norias> zeeshan: that's really for...
[10:36:16] <norias> uh, the deckel pantograph type machines
[10:36:19] <Rab> zeeshan, special ed teacher. But the tests are mandatory for all students. ;)
[10:36:33] <zeeshan> lol
[10:36:35] <zeeshan> nice
[10:36:43] <zeeshan> that is quite dumb
[10:36:52] <norias> i'm sure you can use them for other things
[10:37:01] <zeeshan> norias hm
[10:37:22] <norias> but someone good with those grinders and a pantograph mill
[10:37:24] <norias> back in the day
[10:37:31] <norias> was king of the mold-making shop
[10:37:54] <norias> if i look enough, i can find you a refference for that
[10:38:02] <norias> i think it's on Phil Kerner's site
[10:38:14] <zeeshan> i cant visualize how you'd sharpen an end mill on that
[10:38:32] <zeeshan> especially the end of an end mill
[10:38:39] <tiwake> the grinder has a point thing that rides in the flute of the drill|endmill and you rotate it to keep that point in the flute
[10:38:44] <CaptHindsight> tiwake: were you in the US when home schooled?
[10:39:10] <tiwake> CaptHindsight: yeah... most other countries pretty much don't let you do that
[10:39:48] <norias> it's on phil kerner's site
[10:39:54] <norias> but behind a paywal
[10:40:04] <norias> on the other hand, it's only like $97 for lifetime
[10:40:42] <norias> http://www.thetoolanddieguy.com/
[10:42:00] <gene78> Dee4p do-do on the lathe, what is a good alternate superblock to use for an e2fsck -b?
[10:42:51] <zeeshan> Doh
[10:43:08] <zeeshan> https://www.youtube.com/watch?v=RAUtNy0CeX4
[10:43:09] <zeeshan> free
[10:43:38] <zeeshan> lol
[10:43:39] <zeeshan> nm
[10:43:43] <norias> heh
[10:45:34] <ssi> zeeeee
[10:45:38] <zeeshan> hi
[10:45:41] <ssi> hi
[10:47:23] <zeeshan> man im not looking forward to these 6" holes i gotta drill
[10:47:29] <ssi> "drill"
[10:47:29] <zeeshan> and they gotta be 5 thou from center
[10:47:38] <ssi> oh 6" deep?
[10:47:40] <ssi> or dia
[10:48:28] <zeeshan> 6 deep
[10:48:34] <ssi> that's no fun
[10:48:36] <tiwake> what diameter?
[10:48:46] <tiwake> in a mill or lathe?
[10:49:29] <zeeshan> sec
[10:50:32] <CaptHindsight> tiwake: many actually do, it can also be a problem in the US, the desire to indoctrinate is just too tasty for many administrators
[10:51:17] <CaptHindsight> plus k-12 schooling in the US is a big business now
[10:51:55] <CaptHindsight> and they earn less when your little blood filled meat sacks don't attend
[10:52:08] <ssi> lol
[10:56:52] <tiwake> I'm off to work
[10:56:54] <tiwake> TTFN
[10:57:33] <tiwake> lets hope I get that loan and consequently the house I'm looking at getting
[10:57:43] <zeeshan> .242 dia hole
[10:57:45] <zeeshan> 6" deep
[10:57:50] <zeeshan> .003 max off center
[10:57:52] <archivist> gun drill
[10:57:56] <tiwake> ouch
[10:58:05] <zeeshan> i was thinking drilling from both sides
[10:58:24] <zeeshan> and hoping it meets in the center! :P
[10:58:26] <archivist> a gun drill is better for deep work
[10:58:30] <zeeshan> why
[10:58:39] <zeeshan> it looks very flexible
[10:58:46] <archivist> because its made for that job
[10:59:20] <archivist> the support part is clever, it also needs pressure lubrication to clear chips
[10:59:54] <_methods> 24xd hole lol
[11:00:08] <CaptHindsight> don't the barrels of guns tend to be deep and very straight?
[11:00:20] <_methods> indeed
[11:00:27] <archivist> this is routing to deep hole drillers
[11:00:39] <archivist> routine
[11:00:44] <CaptHindsight> I wonder what they use to drill them?... oh yeah Gun Drill
[11:00:47] <_methods> walter titex drills are good for 30xd
[11:01:15] <_methods> http://www.fms-tools.fi/images/uploads/pdf/XD_Eng.pdf
[11:01:21] <archivist> I have one gun drill bit here did a very good job
[11:01:51] <archivist> managed to use it dry in brass
[11:02:02] <_methods> anything over 30xd you need a gun drill
[11:02:47] <_methods> if you need it to be straight that its
[11:02:52] <_methods> s/its/is
[11:02:57] <archivist> main reason to wander is poor chip control, hence the pressure lube
[11:03:47] <_methods> thru spindle coolant is a must for drilling like that
[11:03:59] <_methods> or thru tool oil like gun drill
[11:04:33] <archivist> some also rotate the job as well as the drill
[11:06:52] <_methods> gonna be a spendy drill
[11:07:06] <_methods> even ghetto 30 xd drillis like $600
[11:08:26] <_methods> i always work very closely with the drill manufacturer when i set up a 30xd + job
[11:09:03] <zeeshan> lol
[11:17:13] <archivist> I managed to scrounge the drill I used :)
[11:17:55] <zeeshan> nm no more gun drill needed
[11:17:58] <zeeshan> decreased plate width
[11:18:04] <archivist> I think it is bigger than .242 so cannot make a large sale :)
[11:19:21] <zeeshan> haha
[11:19:42] <Tom_itx> zeeshan you could alwasys argue the test methods were poor
[11:20:10] <Tom_itx> especially if it's a blind hole
[11:21:03] <zeeshan> haha
[11:21:06] <zeeshan> http://i.imgur.com/TLdU9Zx.png
[11:21:23] <zeeshan> im thinking this might be adequate enough to circulate fluid through to cool the bottom block
[11:21:33] <Tom_itx> oh gawd.. you still on those!
[11:21:41] <zeeshan> ill be on them for at least another month
[11:21:41] <zeeshan> ahha
[11:21:45] <zeeshan> im working on the apparatus
[11:21:46] <zeeshan> concept
[11:22:18] <zeeshan> like i cant just hack one together (i would like to)
[11:22:25] <zeeshan> i need to show heat transfer calculations and all this bs
[11:22:31] <zeeshan> before they'll approve my budget
[11:22:56] <Tom_itx> so you need to spend your budget before they approve it?
[11:23:16] <zeeshan> pretty much :P
[11:24:07] <Tom_itx> it's kinda scary to think that most things in life went to the lowest bidder
[11:24:19] <zeeshan> not necessarily :P
[11:24:22] <zeeshan> dude
[11:24:28] <zeeshan> im thinking instead of all these lame holes
[11:24:28] <Tom_itx> i said _most_
[11:24:38] <zeeshan> why dont i just ball nose the bottom of the plate
[11:24:47] <zeeshan> !
[11:24:52] <Tom_itx> i wondered that a week ago
[11:24:54] <zeeshan> and put a water manifold
[11:24:58] <_methods> hahahahhahahah
[11:25:05] <Tom_itx> you didn't wanna have a tool change as i recall
[11:25:14] <zeeshan> haha that was for something else
[11:25:15] <zeeshan> silly :P
[11:25:22] * Tom_itx knows
[11:25:28] <zeeshan> you ball nose lover
[11:25:43] <Tom_itx> they're wonderful when you're building airplane parts
[11:25:47] <Tom_itx> nothing is flat
[11:28:22] <zeeshan> like for blisks?
[11:35:53] <Tom_itx> what's that?
[11:40:06] <zeeshan> those compressor/turbine blades made from one piece
[11:40:41] <Tom_itx> oh
[11:40:49] <Tom_itx> yeah they make those here too
[11:41:02] <Tom_itx> we didn't
[11:41:41] <zeeshan> what were you makin
[11:43:27] <Tom_itx> all sorts of stuff
[11:44:19] <Tom_itx> i've still got alot of the models
[11:46:36] <jdh> plant next door makes blisk from solids and welded
[11:50:49] <zeeshan> http://i.imgur.com/3KN20Pf.png
[11:50:54] <zeeshan> i feel like something weird is going on here
[11:50:59] <zeeshan> http://i.imgur.com/YET4OAw.png
[11:51:06] <zeeshan> the way that fluid is going to circulate
[11:53:35] <zeeshan> http://www.mcmaster.com/#heat-elements/=x2bwv7
[11:53:37] <zeeshan> anyone use these before?
[11:54:28] <Tom_itx> why?
[11:54:36] <zeeshan> can i just hook em up to a regular pid
[11:54:39] <zeeshan> two of em
[11:54:41] <archivist> point inlet and outlet to promote sensible circulation
[11:54:46] <Tom_itx> they're just heating elements
[11:54:54] <zeeshan> archivist: i might ball nose it
[11:55:06] <zeeshan> archivist: you're talking about the transition right?
[11:55:07] <Tom_itx> i use heating elements on my toaster oven
[11:55:12] <Tom_itx> avr controlled
[11:55:21] <archivist> zeeshan, yes
[11:55:37] <zeeshan> Tom_itx: so basically as long as i don't exceed the current rating of the switching controller
[11:55:39] <zeeshan> i am okay
[11:55:42] <zeeshan> i can put as many as i want in parallel
[11:55:50] <Tom_itx> i suppose yes
[11:55:59] <Tom_itx> i've got 2 and 2 on 2 circuits
[11:56:02] <zeeshan> cause they are like big resistors
[11:56:02] <archivist> or series or a combination
[11:56:05] <zeeshan> er
[11:56:09] <zeeshan> low ohm , high wattage resistors
[11:56:14] <Tom_itx> would have had all 4 but i'd already purchased the triacs
[11:56:31] <zeeshan> triacs are used so you dont blow up a relay
[11:56:32] <zeeshan> right?
[11:56:37] <zeeshan> no hv spike to deal with
[11:56:45] <Tom_itx> i suppose yes
[11:56:53] <Tom_itx> also the opto was a triac opto
[11:57:16] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/toaster_oven/control_sch.png
[11:57:25] <Tom_itx> right corner is the triac circuit
[11:58:02] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/toaster_oven/triac_top2.jpg
[11:58:06] <Tom_itx> and the layout
[11:58:13] <Tom_itx> opto is on the bottom
[11:58:40] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/toaster_oven/triac_bottom2.jpg
[11:58:55] <Tom_itx> coated the copper for more current
[11:58:59] <Tom_itx> not that it needed it
[11:59:19] <Tom_itx> but i wasn't sure.... not all scientific etc on the calcs ya know
[12:00:20] <Tom_itx> those were 2w resistors iirc
[12:00:34] <zeeshan> why were you using an avr
[12:00:42] <Tom_itx> why not?
[12:00:48] <zeeshan> like why not a regular pid controller
[12:00:52] <zeeshan> did you wanna just try to design one?
[12:00:57] <Tom_itx> because i had avrs
[12:01:04] <Tom_itx> and they would do the job
[12:01:39] <Tom_itx> go to sdp-si and tell me if their belt calculator is borked...
[12:02:04] <Tom_L> https://sdp-si.com/eStore/CenterDistanceDesigner
[12:02:19] <Tom_itx> none of the dropdowns show up here
[12:02:48] <archivist> borked here too
[12:03:06] * Tom_itx is gonna call em
[12:03:15] <archivist> designer is probably drunk on broken JS
[12:03:51] <archivist> lots of idiots are breaking sites at the moment
[12:04:35] <_methods> what are the js cdn's down or something?
[12:05:08] <Tom_itx> they blamed their host provider
[12:05:44] <Tom_itx>  /s/host/hosed
[12:06:00] <zeeshan> http://i.imgur.com/N1whRmt.png
[12:06:11] <zeeshan> haha
[12:06:11] <archivist> Tom_itx, I just looked at the source of the page, selects are plain empty
[12:06:15] <zeeshan> what do you think of this
[12:06:18] <zeeshan> 2 heating elements
[12:06:23] <zeeshan> and then the cooler
[12:06:27] <zeeshan> i wonder if it will temp control :[
[12:06:33] <Tom_itx> zeeshan you making a huge reprap now?
[12:06:39] <zeeshan> hahahah
[12:06:41] <archivist> repcrap
[12:06:42] <zeeshan> no
[12:07:31] <Tom_itx> heat the water coming in
[12:07:33] <_methods> hahah you better not make fun of 3d printers that malcolm guy will get all upset
[12:07:40] <Tom_itx> you'll have hotspots on the top
[12:07:52] <Tom_itx> and cool spots on the bottom
[12:07:59] <zeeshan> id let it get to steady state
[12:08:17] <Tom_itx> put about 15 temp sensors all over it to monitor it
[12:08:22] <zeeshan> haha
[12:08:30] <archivist> get busy woth some thermal FEM software
[12:08:34] <archivist> with
[12:08:39] <zeeshan> i will fem it
[12:08:50] <zeeshan> but i am picking your brains for intiution
[12:08:53] <zeeshan> my intuition says it works
[12:08:58] <zeeshan> but it can be wrong :)
[12:09:09] <Tom_itx> no funding...
[12:09:13] <zeeshan> the worse is when you spend hours feming it and it doesnt fkn work
[12:09:19] <zeeshan> and you have to redo your entire study
[12:09:46] <archivist> fem phail due to forgetting the important bit
[12:09:52] <zeeshan> the bottom block is copper
[12:10:01] <zeeshan> middle and top block are aluiminum
[12:10:45] <Tom_itx> what's the target temp?
[12:10:52] <gene78> New copy of binary.hybrid.iso, where is install icon?
[12:10:53] <zeeshan> -10 to 260C
[12:11:11] <zeeshan> designing for -20 to 300C
[12:11:27] <zeeshan> im thinking of keeping the cooler simple
[12:11:40] <zeeshan> and just using a liquid co2
[12:11:47] <zeeshan> liquid co2 + salt mixture
[12:12:01] <zeeshan> only fancy thing ill need is a pump that can handle that temp
[12:13:42] <zeeshan> blah viton can only take 400F
[12:15:29] <archivist> metal seals
[12:15:53] <Tom_itx> use the rubber seals NASA used on the shuttle
[12:15:54] <Tom_itx> :D
[12:18:30] <ssi> lol
[12:19:40] <archivist> or wankel seals guaranteed to fail
[12:20:57] <ssi> boost goes in -----> wankel -------> apex seals come out
[12:24:00] <PetefromTn> Sorry guys while I know wankels have their issues after hearing some built ones local here they are frackin' awesome motors LOL.. Sounds like a damn F1 car when revving almost!
[12:28:15] <ssi> lol
[12:28:53] <Tom_itx> PetefromTn, bud of mine used to race em. our shop was near downtown by tall buildings. he used to take it up the alley and turn off the ignition and fill the chambers with fuel before turning the ignition back on so they would purposely backfire
[12:29:27] <Tom_itx> one way to scare off the crows for sure
[12:29:40] <PetefromTn> yeah these guys are always playing with the 2 step and whatnot making loud noises and giggling like schoolgirls hehe
[12:30:05] * Tom_itx imagines PetefromTn is right there with them giggling too
[12:31:01] <PetefromTn> I never really thought much about mazda cars before but after being around them a lot lately working with these guys I gotta admit they sure are growing on me. I love the braap braaaaap of the motors sound. They just built one making 760 hp and now they are working on a 1k motor.
[12:31:57] <Tom_itx> one run and it's done
[12:32:25] <PetefromTn> LOL I hear ya but apparenlty not...
[12:32:51] <PetefromTn> The 760 HP car has been prowling the streets for quite awhile now.
[12:34:21] <Tom_itx> i guess thinking back on it, he's lucky he didn't break any windows out
[12:35:46] <PetefromTn> Personally I love the interior of the car. Its actually a sweet car and while kinda tight inside it is well laid out. Not saying I am gonna sell my car for one but I would take one if I got a good deal on it. They are building a badass Supra right now 2JZ!!!
[12:36:48] <PetefromTn> anyone know how to add an item to the bookmarks toolbar in Chrome without having it add the frackin
[12:36:54] <PetefromTn> other bookmarks toolbar?
[12:37:17] <PetefromTn> tab rather..
[12:37:45] <_methods> make new folders
[12:37:54] <_methods> then add the bookmark to your folder
[12:38:18] <_methods> it will ask you waht folder you want to add to when you bookmark it
[12:38:44] <PetefromTn> and this allows you to have the little icon added at the top?
[12:38:46] <CaptHindsight> zeeshan: did you figure out your flow rates yet?
[12:38:59] <_methods> what do yo mean?
[12:39:33] <Tom_itx> ff changed the way it does bm now too
[12:39:35] <PetefromTn> I mean I have a bunch of icons for favorited pages atop my screen in the bookmarks toolbar and I want to add more.
[12:39:40] <Tom_itx> i'm not liking it much
[12:39:49] <_methods> ahhh
[12:39:56] <_methods> just add bookmark to toolbar
[12:40:06] <PetefromTn> how?
[12:40:17] <_methods> ok when you hit the bookmark button
[12:40:24] <_methods> hit the add to folder dropdown
[12:40:32] <_methods> then select bookmarks bar
[12:40:49] <_methods> and it will add it directly to your bookmark bar
[12:41:03] <PetefromTn> Wait I just did it..
[12:41:40] <PetefromTn> Just bookmarked it and got the OTHER BOOKMARKS TAB then clicked and dragged the item to the bookmarks toolbar at the top and the Other bookmarks tab disappeared...COOL
[12:42:09] <_methods> yeah you can do it from the manage bookmarks page too
[12:42:15] <PetefromTn> thanks for trying to help ;)
[12:42:19] <_methods> haha np
[12:42:55] <PetefromTn> got a couple items to machine today that are kinda of a quick turnaround for a previous customer
[12:43:12] <PetefromTn> just cleaned out the chip trays and washed down the inside of the machine
[12:43:27] <_methods> nice repeat work is what you want
[12:43:31] <PetefromTn> two damn parts both two sided and are unique
[12:43:44] <PetefromTn> also kinda difficult to hold onto..
[12:43:53] <_methods> soft jaws
[12:43:58] <PetefromTn> Gonna have to make a substrate fixture screw down setup I think
[12:44:06] <_methods> ah
[12:44:08] <_methods> fun fun
[12:44:34] <PetefromTn> I am gonna ante up and buy a shitload of soft jaw blanks here just as soon as I get some extra cash.
[12:44:48] <Tom_itx> make ur own
[12:44:54] <_methods> yeah i need to get a bar of alum and make some myself
[12:45:00] <PetefromTn> this week has been a BAD one for me as far as techno gadjets are concerned damnit
[12:45:14] <PetefromTn> they are so cheap it is not really worth making them
[12:45:21] <Tom_itx> we had several different thicknesses
[12:45:44] <Tom_itx> you never knew what profile you would have to cut in one
[12:45:45] <PetefromTn> ebay has many different packages of them for just a bit more than the damn material costs
[12:45:51] <_methods> hmmm
[12:46:26] <Tom_itx> alot of our material was supplied and we always had scrap
[12:46:40] <PetefromTn> anyways but beloved HTC one decided to stop working in regards to Wifi and Bluetooth
[12:46:56] <PetefromTn> so basically made it useless other than for calls and textx
[12:47:15] <_methods> damn they are about as cheap as the material
[12:47:19] <PetefromTn> then my damn AC adapter for the Laptop I use for all my programming dies on me
[12:47:29] <_methods> gonna have to just order some from ebay i guess
[12:47:31] <PetefromTn> I know right
[12:47:31] <renesis> that sucks
[12:48:11] <_methods> i'm not bitchin hell saves me from having to cut all them up
[12:48:18] <_methods> and drill and cbore
[12:48:20] <PetefromTn> then I finished some parts for my best customer and went to grab my best camera to take some photos since my cellphone is not transmitting and it was giving me issues too...
[12:48:42] <PetefromTn> yeah it is not really worth it unless you just have some material laying around.
[12:48:54] <Tom_itx> made from the finest scrap from Chernybly sold to china
[12:49:01] <_methods> hahahah
[12:49:02] <PetefromTn> LOL probably
[12:50:11] <PetefromTn> machining a bunch of cast iron parts lately shit cuts like butter even with that 1/8 endmill I ordered. Kinda surprised how easy it cut really. Just makes a big mess and have to clean out the machine each time I cut it.
[12:50:21] <ssi> it's dusty
[12:50:43] <_methods> yeah vacuum and airblast is your friend
[12:51:22] <_methods> lots of black boogers
[12:51:23] <PetefromTn> yeah I just blasted air and put down some cloth in the chip trays to catch most of it. Then vacuumed out the trays after I cut it.
[12:51:33] <PetefromTn> no coolant
[12:52:34] <PetefromTn> so I ordered a brand new damn AC charging adapter for my Laptop but until it arrives I am SOL.
[12:52:41] <ssi> :(
[12:52:46] <PetefromTn> Was looking at getting a universal laptop charger
[12:52:48] <PetefromTn> locally
[12:52:54] <ssi> are you IRCing from the cnc computer?
[12:53:09] <_methods> 19v?
[12:53:25] <_methods> too bad you don't have some buck-boosts layin around
[12:53:28] <PetefromTn> but wally world, Office Despot, and Staples all have them online but only stock their fucking most expensive one in the stores
[12:53:32] <_methods> you could just use an old pc power supply
[12:53:44] <PetefromTn> yeah its 19v
[12:53:54] <PetefromTn> no I am on my desktop
[12:53:57] <_methods> yeah buck up a 12v pc supply to 19v
[12:54:16] <PetefromTn> we have like six different computers around here as well as the tablets and cellphones
[12:54:19] <ssi> lol
[12:54:33] <ssi> so you're not so much SOL as "mildly inconvenienced"
[12:54:40] <PetefromTn> but my Post processor is on the damn laptop and I guess I never got around to transferring it to another machine
[12:54:43] <Tom_itx> i hope by the time i need a surface supply ebay has them cheap
[12:54:44] <_methods> what's that place you give your stuff to
[12:54:45] <_methods> goodwill
[12:54:50] <_methods> they usually have tons of them
[12:54:55] <Tom_itx> damn MS and their magnetic plugs...
[12:55:00] <_methods> for like $1
[12:55:08] <gene78> Install and update complete, need amanda-client, not in default repo's, what entry in sources.list do I need?
[12:55:17] <_methods> anytime i need a cheap power supply for a project i hit them up
[12:55:38] <Tom_itx> i can't count the number of supplies i've replaced around here
[12:55:58] <jthornton> I'm so glad I got BackupPC working
[12:55:59] <PetefromTn> just spent all our spare cash on brand new couches, kitchen table and chairs and materials for our kitchen so this could not come at a better time LOL
[12:56:06] <_methods> yeah i have a stack of old server power supplies i use for more voltage "intensive" projects lol
[12:56:12] <Tom_itx> jthornton, works good ehh?
[12:56:23] <jthornton> so far
[12:56:25] <ssi> _methods: yea I was running my bitcoin asic farm on a DL380G5 supply
[12:56:29] <ssi> 12V @ 72A :D
[12:56:37] <_methods> i made a battery tab spot welder out of a pair
[12:56:46] <_methods> yeah mega amps
[12:56:54] <_methods> server power supplies are beast
[12:57:06] <_methods> you can usually crank the voltage up a bit past 12 too
[12:57:16] <_methods> with a few mods lol
[12:57:18] <ssi> yeah
[12:57:33] <_methods> some make it easy with a pot
[12:57:57] <_methods> thx PetefromTn for killin my soft jaw plans
[12:58:00] <PetefromTn> this is a 19v 3.42A model PA3714U-1ACA
[12:58:10] <PetefromTn> heh
[12:58:13] <PetefromTn> sorry dude
[12:58:15] <_methods> hahah
[12:58:17] <_methods> jk
[12:58:29] <PetefromTn> you should thank me for saving you a shitload of wasted time
[12:58:29] <_methods> kinda glad now i really didn't want to saw all that up
[13:00:15] <_methods> gene78: i think it's in backports
[13:00:21] <_methods> if you're using debian
[13:03:03] <_methods> https://packages.debian.org/wheezy/utils/amanda-client
[13:04:27] <_methods> looks like it should be in the regular repos for wheezy though?
[13:10:46] <_methods> http://www.miteebite.com/images/product_pages/t-slot_kit_1.jpg
[13:10:57] <_methods> heh i always wondered how those little things worked
[13:11:06] <_methods> they just turned the screw head eccentric
[13:16:04] <renesis> yeah they have cam heads
[13:16:32] <renesis> i have some are like ground down button heads
[13:26:14] <_methods> yeah i've never used those before i've always used the big toe clamps with the screw that goes into the foot at a 45
[13:26:30] <_methods> used plenty of other mitee bite clamps before though
[13:26:38] <_methods> the ID clamps are the shiznit
[13:29:24] <ssi> lol so a couple weeks ago I machined a prop spacer for a friend of mine for his pitts
[13:29:34] <ssi> he needed like 1.75" taken off the length
[13:29:52] <ssi> he's flown it ~25 hours since we did it
[13:30:00] <ssi> yseterday he uncowled it and about shit himself
[13:30:29] <ssi> the flywheel wasn't tigth between the crank flange and the spacer, there was like a .030" gap, and you could rock the flywheel through 10 degrees or so
[13:31:02] <ssi> turns out the counterbore for the crank nose wasn't deep enough and it was tightening up on the nose
[13:31:24] <ssi> the prop was solid but the flywheel has been rattling around and peening the spacer
[13:32:16] <ssi> I faced the back of the spacer where it was peened, and opened up the counterbore
[13:32:23] <ssi> blued up the back of the spacer and we test-torqued it
[13:32:36] <_methods> wow
[13:32:52] <_methods> poop in da pants moment
[13:32:55] <ssi> yep
[13:33:07] <ssi> he's been doing a lot of gyroscopic maneuvers in it too
[13:33:18] <ssi> only thing really holding the prop solid was the bushings and bolts
[13:33:38] <_methods> centrifugal force hehe
[13:34:19] <ssi> gyroscopics are really hard on the prop and crank flange
[13:34:23] <_methods> i bet
[13:34:33] <_methods> speed up, slow down, climb, dive
[13:34:47] <ssi> snap rolls
[13:35:33] <ssi> I just texted him and told him to pull the flywheel before he puts it back together and make sure it didn't beat up the crank flange too bad
[13:35:43] <ssi> he said that there are a few marks on it and he's gonna do a dye pen check before he reassembles
[13:42:50] <FinboySlick> For smart cookies out there: Imagine a setup like figure (c) in this http://www.physics.sjsu.edu/becker/physics51/images/28_09_Magnetic_filed_lines.jpg with a permanent magnet in the gap. How would one maximize the input current to mechanical force beyond making the gap as small as possible? I'm assuming that there would be loss in the metal core.
[13:44:56] <SpeedEvil> What are you trying to do
[13:45:02] <_methods> super cooling
[13:45:08] <SpeedEvil> If you're trying to make a motor, look at existing motors.
[13:45:17] <SpeedEvil> They are the result of a century of answering that question
[13:45:31] <SpeedEvil> Good motors are >95% efficient
[13:45:42] <FinboySlick> SpeedEvil: Pondering a 'magnetic' pull rod mechanism for a spindle.
[13:46:00] <_methods> a drawbar?
[13:46:11] <FinboySlick> SpeedEvil: It'd be a ~3mm travel linear motor, I guess.
[13:46:29] <SpeedEvil> you mean you want to make basically a solenoid?
[13:46:38] <SpeedEvil> Or do you want to be able to accurately control it
[13:46:48] <FinboySlick> No accuracy, stops when it bumps.
[13:46:51] <SpeedEvil> What force do you need
[13:48:04] <FinboySlick> SpeedEvil: I imagine a couple hundred pounds or more. But not sustained for very long.
[13:48:16] <FinboySlick> (it wouldn't be for a big mill)
[13:49:04] <SpeedEvil> That's a long enough throw and enough force to make solenoids uncomfortably large
[13:49:09] <FinboySlick> I'm more curious on what factors other than the obvious (number of turns, distance) that one should consider when designing a solenoid actuator.
[13:49:40] <PetefromTn> kinda surprised you did not hear or feel the problem with that prop..
[13:50:15] <ssi> PetefromTn: the prop was solid... and at speed, the flywheel would have straightened itself out due to centrifugal force
[13:50:20] <SpeedEvil> FinboySlick: saturation matters - you can only get so much magnetic field into iron before it stops being a magnetic conductor - and there isn't any batter
[13:50:24] <ssi> it actually ran smoother after we machined the spacer :P
[13:50:55] <PetefromTn> sounds like you guys like to live dangerously ;)
[13:51:06] <SpeedEvil> FinboySlick: I would look at a car door-lock actuator and a lever
[13:53:00] <FinboySlick> SpeedEvil: OK. Saturation isn't something I readily had in mind so that's a good catch. With the lever thing though, wouldn't that be something to optimize? I'm figuring that the more travel distance you have, the more magnetic loss you have so while you gain from the actual lever, you loose on the distance. I guess there would be a sweet spot.
[13:53:16] <Jymmm> FinboySlick: with remote control http://www.ebay.com/itm/4-Door-Power-Central-Lock-Kit-With-2-Keyless-Entry-Car-Remote-Control-Conversion-/400330362846
[13:53:23] <ssi> lol
[13:53:33] <Rab> A car door lock actuator doesn't have a couple of hundred pounds of force.
[13:53:37] <SpeedEvil> FinboySlick: yes - car door lock mechanisms use little geared motors, not solenoids for this reason
[13:53:43] <PetefromTn> http://i.imgur.com/0H0xazD.jpg
[13:53:48] <SpeedEvil> Rab: no, but it will usually have ~30mm or throw
[13:53:58] <Rab> SpeedEvil, oh, you mean an example of a linear actuator?
[13:54:00] <SpeedEvil> Rab: and a force of ~10kg
[13:54:02] <SpeedEvil> yes
[13:54:21] <SpeedEvil> Rab: so with a lever, it goes to 3mm and 100kg
[13:54:53] <Rab> FinboySlick, if you've got compressed air, pneumatics seem like a shoe-in.
[13:55:12] <Jymmm> FinboySlick: $5 USA free shipping http://www.ebay.com/itm/UNIVERSAL-POWER-DOOR-LOCK-ACTUATOR-MOTOR-12-Volt-Car-Auto-Brand-New-/400583186980
[13:55:36] <FinboySlick> Rab: Yes, obviously. But I was wondering about an all electric solution.
[13:55:44] <Rab> I wonder if power locks are cammed, or geared, or both.
[13:56:06] <FinboySlick> To be clear, that's just me bouncing ideas here. I'm quite a long way from actually trying to implement it.
[13:56:11] <Rab> http://s.hswstatic.com/gif/power-lock-actuator2.jpg
[13:56:32] <_methods> https://www.grizzly.com/products/Electric-Power-Drawbar/H8368
[13:57:26] <Jymmm> _methods: $1000 phuk that!!
[13:57:31] <_methods> hahah
[13:57:38] <FinboySlick> Jymmm: That's more or less what I was thinking.
[13:57:46] <FinboySlick> A thousand bucks, I'll buy a compressor ;)
[13:57:53] <_methods> you can use and electric impact wrench
[13:57:55] <_methods> and modify it
[13:58:02] <Jymmm> FinboySlick: Buy the first one and connect all four together =)
[13:58:35] <FinboySlick> Jymmm: Thought of that too. But again, I'm not on the implementation side of things yet ;)
[13:58:51] <_methods> http://www.cnczone.com/forums/benchtop-machines/99601-cnc.html
[13:59:25] <Jymmm> But for $5, that could make for a cheap lock. Just attach 1/2" round bar to it
[14:00:16] <FinboySlick> The impact wrench thing is what I'd be trying to avoid. Seems very mechanically harsh on the whole thing.
[14:01:40] <FinboySlick> Ganging up a bunch of little actuators with proper leverage could be pretty neat though.
[14:11:53] <_methods> oh and back
[14:11:56] <_methods> kinda
[14:12:33] <XXCoder1> some network issues it seems tpday
[14:12:54] <_methods> poor freenode
[14:31:16] <XXCoder1> yeah
[14:35:23] <norias> no
[15:50:52] <asdfasd> http://mcu-bg.com/mcu_site/download/file.php?id=8380
[15:52:16] <XXCoder1> no.
[15:53:59] <malcom2073> Everyone still would've failed, but they would remember which end of the sine goes up on which side :P
[15:56:04] <furrywolf> ?
[16:07:45] <zeeshan> [12:59:18] <ssi> boost goes in -----> wankel -------> apex seals come out
[16:07:46] <zeeshan> ROFL
[16:10:32] <furrywolf> lol
[16:10:43] <zeeshan> that will never get old for me
[16:10:54] <malcom2073> Boost conversion device.
[16:22:48] <Deejay> gn8
[16:43:47] <Tom_itx> zeeshan i can see them using one in a blown dragster
[16:44:05] <Tom_itx> like.. blown all over the track
[16:45:02] <zeeshan> when they blow
[16:45:05] <zeeshan> they arent too catastrophic
[16:45:08] <zeeshan> ill give them that
[16:45:19] <zeeshan> they do alot of damage, but its not like a connecting rod out of a block
[16:46:14] <Tom_itx> they probably just lose power and sound funny
[16:46:23] <zeeshan> well for me it's been one rotor goes
[16:46:30] <zeeshan> and if you dont stay on the throttle, and let it die out
[16:46:39] <zeeshan> you cant get it back started again cause theres not enough compression
[16:47:00] <zeeshan> it sounds like 2 pistons not firing on a 4 banger
[17:38:29] <zeeshan> http://www.ebay.com/itm/Dell-Optiplex-775-Heat-Pipe-Heatsink-PN-D9729-/171335719485?pt=LH_DefaultDomain_0&hash=item27e4679a3d
[17:38:33] <zeeshan> hmm
[17:38:37] <zeeshan> if i mount two of these
[17:38:44] <zeeshan> one on the hot block and one on the cold block
[17:39:00] <zeeshan> i wonder if they can help keep the ambient air around the sample at the temperature i want
[17:40:01] <malcom2073> Nice
[17:41:11] <malcom2073> I love heatsinks
[18:00:44] <Crom> zeeshan, that's a great idea... Peltier cooler are great, power hogs though
[18:01:02] <zeeshan> not using peltier chips :/
[18:01:18] <Crom> I wonder how many calories minute you get transferred at 60w
[18:06:16] <Tom_itx> zeeshan use a couple fuel rods
[18:07:13] <zeeshan> ??
[18:07:28] <Tom_itx> U235
[18:07:56] <Tom_itx> you should get plenty of heat from them
[18:14:19] <zeeshan> http://i.imgur.com/56JPzOp.png
[18:14:27] <zeeshan> currently im cooling the bottom block and middle block
[18:14:33] <zeeshan> i mean heating the middle block..
[18:14:40] <zeeshan> i need to ensure the ambient air is at the same temp :/
[18:15:44] * furrywolf wonders why zeeshan's project sounds like it's been complicated
[18:15:53] <furrywolf> whatever happened to just a peltier or two?
[18:19:53] <zeeshan> need 260C to -10
[18:19:56] <zeeshan> peltier isn't going to do that well
[18:20:02] <zeeshan> at the rates i want
[18:20:15] <zeeshan> i wanna be able to drop 10C / min
[18:20:32] <zeeshan> and when i say 10C per min, i mean uniform 10C / min throughout the chamber
[18:21:09] <furrywolf> dry ice?
[18:21:21] <zeeshan> yea im planning to circulate dry ice
[18:21:24] <zeeshan> well liquid co2
[18:21:45] <furrywolf> co2 is only liquid under high pressure. you're finding some way to make this more complicated. :P
[18:21:55] <zeeshan> i can use liquid n2 too
[18:22:17] <furrywolf> yes, you could use liquid n2. do they sell liquid n2 at grocery stores where you are? because they do sell dry ice...
[18:22:31] <zeeshan> im not planning to buy my supplies from the grocery store
[18:22:32] <zeeshan> lol
[18:22:38] <furrywolf> go for simple with common materials, not expensive with exotic materials.
[18:22:54] <zeeshan> i was also considering -20C chiller
[18:22:57] <zeeshan> with glycol
[18:23:07] <zeeshan> im not worried about finding a medium that can cool it down that low
[18:23:13] <zeeshan> im worried about keeping the chamber air at that
[18:23:24] <furrywolf> how much thermal mass do you have? 10C/minute seems well within peltier territory...
[18:23:39] <zeeshan> im trying to figure out a way to integrate the current heating block + cooling block
[18:23:44] <zeeshan> in a way that i can attach some sort of h eatsink to it
[18:23:52] <zeeshan> and and use a fan to circulate air
[18:23:57] <furrywolf> if not, get two cold plates, dump dry ice on one, and circulate glycol to the one in your chamber.
[18:25:01] <zeeshan> https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcSRZ6LnzxFGuOVRx63f2uznNacggwG94upvUlnTAD6GUhP4xJJMmQ
[18:25:03] <furrywolf> 260C is pretty hot, though... what's glycol boil at? might need silicone heat exchanger fluid. in which case you can just heat the fluid externally and have nothing but a single block in your chamber.
[18:25:07] <zeeshan> maybe i should just attach a shit load of these
[18:25:22] <zeeshan> furrywolf: i expect it to boil at that temp
[18:25:35] <zeeshan> but even with boiling, it should cool
[18:26:01] <furrywolf> the url you pasted is nothing but a captcha. I'm not going to solve a captcha for a random link.
[18:26:16] <zeeshan> http://www.conradheatsinks.com/images/1004_c.JPG
[18:26:35] <furrywolf> a random heatsink
[18:26:39] <zeeshan> yea
[18:26:39] <zeeshan> haha
[18:26:48] <zeeshan> if i mount that on all four corners of the assembly
[18:26:53] <furrywolf> why the fuck does a random heatsink need https and captchas to protect it? :P
[18:26:59] <zeeshan> and blow a fan from underneath, it should work
[18:27:03] <zeeshan> simulation will tell!
[18:28:06] <zeeshan> http://www.mcmaster.com/#8822t13/=x2gznb
[18:28:09] <zeeshan> oo these are sexy
[18:29:21] <ffurrywol> <furrywolf> rather than heating inside the chamber, heat your heat transfer fluid externally (with an off-the-shelf heater module), and have a mixing valve to fluid cooled with a cold block with some dry ice on top.
[18:29:24] <ffurrywol> <furrywolf> why the fuck does a random heatsink need https and captchas to protect it? :P
[18:30:15] <zeeshan> conduction of the heating element will heat things faster
[18:30:18] <zeeshan> vs circulating fluid
[18:30:54] <ffurrywol> but you can circulate fluid all over the place to evenly heat side heatsinks, etc
[18:31:12] <ffurrywol> and I thought you were extremely limited on space?
[18:31:19] <zeeshan> not anymore
[18:31:19] <zeeshan> lol
[18:31:25] <zeeshan> not using this on the 3d microscope anymore
[18:32:17] <ffurrywol> ah
[18:34:12] <zeeshan> =/
[18:36:27] * ffurrywol tries do design things simply and cheaply
[18:37:30] <zeeshan> sometimes simple and cheap isn't the solution! :P
[18:37:38] <zeeshan> its be so much more compact using peltiers
[18:37:55] <zeeshan> most peltiers cant handle 300C unless they are theromgenerators
[18:38:15] <ffurrywol> yeah, you seem to have expanded your temperature range since last time you mentioned this project.
[18:38:24] <zeeshan> yes things, have changeed :P
[18:38:41] * zeeshan needs a 1.5x4 heat sink
[18:39:20] <ffurrywol> you mean you need a random heatsink and a saw?
[18:39:26] <zeeshan> haha
[18:39:37] <zeeshan> i want the most amount of fins in that area
[18:39:48] <zeeshan> or in other words, the most surface area in fins to fit in that area
[18:40:18] <ffurrywol> the most surface area does not result in the most cooling
[18:40:30] <zeeshan> it results in the most heat transfer
[18:40:41] <zeeshan> thats the point of fins
[18:40:41] <ffurrywol> for convection you want thicker fins further spaced, getting thinner the harder you can blow air through them.
[18:40:54] <ffurrywol> transferring heat to stagnant air doesn't help
[18:41:05] <zeeshan> youre right that you need more pumping power
[18:41:09] <ffurrywol> you need to both transfer the heat to the air, and let the air move. these are counter to each other.
[18:41:12] <zeeshan> but that isn't a design constrain
[18:41:18] <zeeshan> even if it takes 10 hp to pump air
[18:41:21] <zeeshan> its ok :P
[18:44:37] * ffurrywol notes dot5 brake fluid is good to 260C
[18:44:46] <zeeshan> hey
[18:44:48] <zeeshan> thats a good idea
[18:44:48] <zeeshan> LOL
[18:45:00] <zeeshan> i wonder what its specific heat capacity is
[18:45:02] <zeeshan> vs water
[18:45:22] <ffurrywol> it's silicone, which is also used for heat transfer fluid, so it can't be total crap.
[18:45:59] <zeeshan> Polysiloxanes have a specific heat capacity of 1.3 to 1.5 kj/kgk
[18:46:03] <zeeshan> water 4.2kj/kgk
[18:47:26] <zeeshan> not terrible
[18:47:37] <zeeshan> and dot5 fluid is cheap! :P
[18:53:01] <zeeshan> .3125/2
[18:53:37] <Tom_itx> .15625
[18:54:05] <zeeshan> accident
[18:54:08] <zeeshan> =]
[18:54:33] <Tom_itx> careful where you put those fingers
[18:54:51] <Tom_itx> you might not get to keep em
[18:55:54] <Tom_itx> i should stop trolling and get motivated to do something on my control
[18:58:40] <_methods> counterboring with a hand drill is much more challenging than cbore in mill
[19:00:13] <ffurrywol> dot5 fluid is not cheap. it is, however, much cheaper than things sold as heat transfer fluids.
[19:00:49] <ffurrywol> unless you have some connection somewhere that'll get them cheap in quantities smaller than a drum.
[19:01:51] <ffurrywol> the local auto parts store wants $100/gallon. that's not cheap. :P
[19:02:55] <ffurrywol> it's cheaper tham BMW power steering fluid, however.
[19:03:24] * ffurrywol asked about the price of it once, back when owning a bmw... $32/qt.
[19:04:34] <zeeshan> well its cheap in brake fluid quantities
[19:04:40] <zeeshan> (for its intended application)
[19:04:42] * ffurrywol used generic atf, and it worked just as well
[19:06:10] <CaptHindsight> zeeshan: I found you some glycols good to 300C +
[19:06:40] <ffurrywol> the advantage of dot5 is you can get it at the local auto parts store, in a $10 size container, rather than needing a specialty supply company and ordering a bucket...
[19:07:45] <zeeshan> CaptHindsight: really? :D
[19:07:48] <zeeshan> cheap?!
[19:09:06] <CaptHindsight> how many KG do you need?
[19:10:11] <ffurrywol> 1
[19:10:13] <ffurrywol> 0.5
[19:10:20] <CaptHindsight> Density 1.1255 g/mL
[19:10:28] <zeeshan> kg?!
[19:10:28] <ffurrywol> depends on how much he spills. :P
[19:10:39] <zeeshan> 2-3 gallons would be nice!
[19:10:43] <zeeshan> is it expensive?
[19:11:03] <CaptHindsight> probably a 20Kg pail
[19:11:07] <ffurrywol> ... gallons?! how big is this thing you're building?
[19:11:16] <CaptHindsight> Triethylene glycol
[19:11:22] <zeeshan> keeping that fluid at low temp is always good thin furry
[19:11:29] <zeeshan> more fluid to hold that temp
[19:11:39] <zeeshan> that way when i control the solenoid, it will stay at the intended temp
[19:11:48] <zeeshan> a 5 gallon pail would be awesome
[19:12:07] <ffurrywol> ... awesome != practical or affordable
[19:12:19] <zeeshan> ffurrywol: you dont know the budget im working with! :P
[19:12:22] <CaptHindsight> the Dow version: Boiling Point at 760 mm Hg 288.0°C
[19:12:35] <CaptHindsight> but there's another that goes to ~320C
[19:12:36] <zeeshan> who is this dow company
[19:12:42] <zeeshan> i keep hearing their name
[19:12:43] <ffurrywol> perhaps, but I do know that if your budget is that large, my consulting fee is $500/hr, starting a couple months ago. :P
[19:12:52] <ffurrywol> ... who is dow? lol
[19:12:54] <zeeshan> ffurrywol: dont have to help :P
[19:13:39] <zeeshan> this heat sink thing LOOKS COOL
[19:13:40] <zeeshan> to me!
[19:14:16] <zeeshan> http://gyazo.com/26a85e127043bbafcf72aa8c86b59e16
[19:14:26] <ffurrywol> asking "who is dow" is like asking "who is microsoft" or "who is the united states". http://en.wikipedia.org/wiki/Dow_Chemical_Company
[19:14:46] <zeeshan> im thinking a big ASS fan
[19:14:51] <zeeshan> under neath this!
[19:15:02] <CaptHindsight> Triethylene Glycol Ethyl Ether (TGEE)* and MPEG350
[19:19:33] <zeeshan> ah
[19:19:35] <zeeshan> they own union carbide!
[19:19:38] <zeeshan> thats a brand i know
[19:20:30] <CaptHindsight> TGEE is US$1.40/lb
[19:20:40] <zeeshan> how many gallons is that
[19:20:44] <zeeshan> whats the density
[19:21:34] <CaptHindsight> TGEE Density (g/cm 3 ) 1.02
[19:21:43] <CaptHindsight> so close to water
[19:22:08] <CaptHindsight> $3.08 usd / Kg
[19:23:32] <zeeshan> g/cm^3 ; p = m/V ; V=m/p = 1000/1.02 ; 980.39 cm^3
[19:24:01] <zeeshan> .98 L ; .259 gallon
[19:24:29] <zeeshan> so about 12 bux a gallon
[19:24:30] <zeeshan> not bad
[19:25:55] <CaptHindsight> CAS Number 112-60-7
[19:26:18] <CaptHindsight> Boiling Point @ 760 mm Hg, °C (°F) 329 (625) Decomposes
[19:27:09] <ffurrywol> I'm getting really sick of my connection.
[19:33:10] <LeelooMinai> I would buy few km of cable and connect to civilisation:)
[19:34:52] <LeelooMinai> ffurrywol: .- .-. . / -.-- --- ..- / - .... . .-. . ..--..
[19:37:26] <CaptHindsight> DOT 5/.1 boiling point 260C
[19:38:15] <LeelooMinai> Making pancakes?
[19:41:59] <zeeshan> CaptHindsight: can you give the link to tgee
[19:42:02] <zeeshan> i wanna read the msds
[19:45:55] <zeeshan> there has to be a fan that can take 300C!
[19:49:36] <Crom> My grandma lived Mr. Dow of Dow Chemicals house in Piedmont, CA behind Oakland. He built it after the 1906 Earthquake
[19:49:49] <Crom> lived in
[19:50:01] <TekniQue> Question about G code and linuxcnc
[19:50:02] <Crom> I lived there a time or 3
[19:50:18] <Crom> TekniQue, ask away
[19:50:19] <TekniQue> I was milling something today, haven't used my mill in quite a couple years
[19:50:42] <TekniQue> cutting profiles in a piece of plastic, used cambam to generate the G-code
[19:51:05] <TekniQue> problem is, I started out with too much speed and notices that the controller was taking shortcuts around corners
[19:51:30] <TekniQue> so instead of coming to a full stop at corners it'd skip the corner to save on deceleration
[19:51:52] <Crom> That's G64,
[19:52:13] <Crom> google G64 G61 G61.1
[19:52:30] <Crom> Constant speed vs. exact cut
[19:52:43] <TekniQue> thanks
[19:53:28] <Crom> there is a setting for how far away from the actual line you'll allow the mill to get
[19:54:10] <furrywolf> I thought the default was "close enough you won't notice"
[19:55:16] <Crom> that's the second G61,G64 in 2 weeks
[19:55:42] <zeeshan> http://i.imgur.com/Xf6Hj2F.png
[19:55:50] <zeeshan> those fan blades were fun to make
[19:56:09] <TekniQue> mhm
[19:56:16] <TekniQue> I found the setting in Cambam
[19:57:43] <Crom> I haven't used CamBam
[19:57:53] <TekniQue> It's pretty basic
[19:58:25] <TekniQue> can import DXF
[19:58:26] <Tom_itx> zeeshan make it a round chamber
[19:58:36] <Crom> I tend to do all my stuff G61 since I'm cutting gears or slots
[19:58:39] <TekniQue> and then you select elements of the DXF and convert them to machining operations
[19:58:39] <zeeshan> Tom_itx: no
[19:58:54] <Crom> zeeshan, no no Ovoid!
[19:59:03] <zeeshan> Tom_itx: harder to form and mount lol
[19:59:12] <zeeshan> but better circulation!
[19:59:44] <Crom> ok I'm off to the creator space... trying to get the RepRap going
[20:00:01] <Crom> board it came with I can't get to talk to the computer
[20:00:23] <Crom> so I'm swapping it out for a Geeetech Melzi
[20:01:57] <zeeshan> i think im gonna have to use a remote shaft
[20:02:14] <zeeshan> a shaft to place the fan blade inside the chamber, while the motor is outside
[20:02:18] <zeeshan> so it doesnt blow up the motor
[20:02:22] <zeeshan> i cant find a motor that can take 300C :P
[20:05:31] <zeeshan> Tom_itx: i like your round idea.

[20:07:14] <CaptHindsight> http://www.inchem.org/documents/sids/sids/eges.rev.pdf
[20:07:31] <zeeshan> that firest thing says flash point 182 - 213 C
[20:08:43] <CaptHindsight> http://msdssearch.dow.com/PublishedLiteratureDOWCOM/dh_004d/0901b8038004d042.pdf?filepath=ethyleneglycol/pdfs/noreg/612-00004.pdf&fromPage=GetDoc
[20:09:33] <furrywolf> use a hydraulic motor running off your circulating thermal fluid. :P
[20:10:28] <CaptHindsight> zeeshan: http://www.dow.com/ethyleneglycol/about/properties.htm
[20:10:33] <furrywolf> the more you try to change the temperature, the faster the fan runs. :)
[20:10:55] <zeeshan> im confused
[20:11:00] <zeeshan> the flash point is at 177C
[20:11:03] <zeeshan> but the boiling point is at 288C?
[20:11:05] <zeeshan> whats going on
[20:11:28] <furrywolf> lol
[20:11:34] <CaptHindsight> you read too slow :)
[20:12:02] <_methods> https://www.youtube.com/watch?v=lr2r66Ko260
[20:12:07] <zeeshan> it freezes at -4.3
[20:12:09] <zeeshan> !
[20:12:19] <CaptHindsight> http://www.inchem.org/documents/sids/sids/eges.rev.pdf page 10
[20:12:45] <CaptHindsight> zeeshan: whats your range?
[20:12:50] <zeeshan> -10 to 260
[20:13:03] <CaptHindsight> all then throw some methanol in
[20:14:04] <CaptHindsight> http://www.dow.com/ethyleneglycol/prod/tetraeg.htm
[20:14:22] <CaptHindsight> with a little something with a lower freezing point
[20:16:01] <CaptHindsight> if they are both in solution that will extend their temp range, especially in a sealed system
[20:17:56] <CaptHindsight> TetraBE 332 c - -33
[20:18:24] <CaptHindsight> CAS No. 1559-34-8

[20:20:15] <CaptHindsight> http://www.hitech-chemicals.com/msds2/butyl_triglycol_ether_MSDS.pdf
[20:22:43] <zeeshan> lol
[20:22:46] <zeeshan> im going crazy with this design
[20:22:52] <zeeshan> without worrying about manufacturing it
[20:22:56] <zeeshan> ..
[20:28:03] * furrywolf mentioned that earlier
[20:28:26] <zeeshan> ill water jet a lot of it
[20:29:52] <CaptHindsight> zeeshan: I'd mix the two types of glycol or if you can find http://www.hitech-chemicals.com/msds2/butyl_triglycol_ether_MSDS.pdf
[20:30:17] <CaptHindsight> since it covers the whole temp range
[20:55:20] <zeeshan> CaptHindsight: ill look more into it when selecting heat trandsfer fluid
[20:55:33] <zeeshan> but now i have a few choices!
[21:06:09] <CaptHindsight> zeeshan: http://www.dow.com/heattrans/pdfs/DispellingTheMyths.pdf
[21:07:37] <zeeshan> CaptHindsight: you really like chemicals dont you!
[21:08:20] <CaptHindsight> I'm more materials science now
[21:09:38] <CaptHindsight> zeeshan: it's more fun when you know your way around lots of different tech
[21:10:01] <zeeshan> CaptHindsight: i dont know, it doesnt interest me a lot
[21:10:04] <zeeshan> the polymers grew on me
[21:10:10] <zeeshan> i wasn't a big fan of them either...
[21:10:16] <zeeshan> i really like structural and forming
[21:10:29] <CaptHindsight> there is just so much you can do with it
[21:11:04] <CaptHindsight> so much that hasn't even been touched yet
[21:11:25] <CaptHindsight> I need to brush up on my biology
[21:13:36] <CaptHindsight> i stated working on water soluble polymers recently (post cure) now I'm looking at grafting water soluble proteins onto monomers which is a really new field
[21:14:32] <CaptHindsight> or proteins from animal cell walls onto monomers and oligomers to make nanomachines that the immune system won't attack
[21:14:47] <zeeshan> are you working in r&d at your work place?
[21:14:59] <zeeshan> that is cool stuff!
[21:15:10] <CaptHindsight> custom tailored synthetic virus
[21:17:52] * furrywolf would love to have an interesting job
[21:18:20] <CaptHindsight> shape memory polymers are neat since they combine polymers with mechanics
[21:19:18] <CaptHindsight> zeeshan: and like you sai the chemists didn't really understand them since they really work like little springs tied together at the ends with different sprint rates
[21:19:24] <CaptHindsight> sai/said
[21:19:37] <CaptHindsight> sprint/spring
[21:19:48] <CaptHindsight> time to bbl, too many typos :)
[21:20:00] <zeeshan> haha
[21:21:33] <CaptHindsight> furrywolf: you should get out of whatever you are doing and work somewhere with your all-around tech skills
[21:21:44] <zeeshan> i forsee a LOT of slip roll action in my future :(
[21:22:42] <zeeshan> http://i.imgur.com/19zh7bt.png
[21:23:14] * Tom_itx giggles a little
[21:23:15] * furrywolf is driving a delivery van
[21:23:25] <zeeshan> Tom_itx: its all your fault!
[21:23:31] <zeeshan> all for the sake of nice circulation
[21:23:33] <zeeshan> all this round stuff
[21:24:04] <furrywolf> that looks overcomplicated.
[21:24:15] <zeeshan> make it better
[21:24:19] <zeeshan> and easier to fab
[21:24:25] <zeeshan> all this stuff, i can easily make
[21:25:29] * zeeshan waits for furry's improvements
[21:25:44] * furrywolf waits for consulting fee
[21:25:55] * zeeshan negates furrywolf's earlier comment
[21:26:23] <furrywolf> how big is your sample?
[21:26:27] <furrywolf> (the thing being tested)
[21:26:44] <zeeshan> 2" diameter
[21:26:52] <zeeshan> i might move to 3"
[21:26:53] <zeeshan> max
[21:27:01] <furrywolf> and how big is that thing you designed to put it in? lol
[21:27:07] <zeeshan> about 12"
[21:27:08] <zeeshan> :D
[21:27:14] <zeeshan> with 2" of insulation layer
[21:27:31] <zeeshan> i will optimize later, i just need a bare bones to start heat transfer simulation on
[21:27:47] <furrywolf> are you trying to heat/cool the sample by conduction (directly sitting on something), or only by changing the ambient air around it?
[21:27:54] <zeeshan> furrywolf: both
[21:28:28] <zeeshan> so forced convection and conduction
[21:28:31] <furrywolf> how does it to do both when the middle looks hollow?
[21:29:04] <zeeshan> there are a lot of middles
[21:29:07] <zeeshan> which middle haha
[21:29:29] <zeeshan> are you talking about the big gaping hole in the top lid?
[21:29:43] <furrywolf> can you skip convection and use radiation heating, with an IR thermometer to measure surface temp and adjust ir source appropriately?
[21:29:55] <zeeshan> doesnt cool
[21:30:42] <furrywolf> correct, but if the air around it is cold, and you turn the heat off...
[21:31:24] <zeeshan> those heating elements in there are like 25$ each
[21:31:26] <zeeshan> and theres two
[21:31:30] <zeeshan> 750W
[21:31:35] <zeeshan> or 500W (i forget)
[21:32:46] * furrywolf adds wheels to it and christens it lunokhod
[21:32:48] <zeeshan> i wonder how quickly you can blow up an ir bulb
[21:32:58] <zeeshan> a heating bulb by cycling it
[21:34:10] <furrywolf> given as printer fusers last gazillions of cycles, I'd say you have to work at it.
[21:35:19] <zeeshan> which hole were you talkin about??
[21:35:48] <furrywolf> the greenest area in the center
[21:36:06] <zeeshan> thats where the film goes
[21:36:09] <zeeshan> and air blows from the bnottom side
[21:36:25] <zeeshan> the top of the film thats exposed in the chamber is what im trying to convectively cool/heat
[21:36:47] <zeeshan> and the bottom of the film is what im trying to cool / heat through conduction->then convection of the air
[21:36:55] <zeeshan> thats trapped ballooning the film
[21:37:24] <furrywolf> so there is no actual conduction to the film, then?
[21:37:53] <zeeshan> very little if any
[21:38:01] <zeeshan> because its a really good insulator
[21:38:11] <zeeshan> like to give you a feel for it
[21:38:23] <zeeshan> i had the film at 260C and i opened the oven door and i grabbed it with bare hands
[21:38:27] <zeeshan> within 10 seconds..
[21:38:57] <furrywolf> so there's compressed air on bottom, outside air pressure on top?
[21:39:10] <zeeshan> yea ambient on the top
[21:39:27] <zeeshan> im gonna have a small gap to ensure it never pressurizes
[21:39:31] <zeeshan> (the ambient side)
[21:40:03] <furrywolf> yes, you'll need a decent amount of venting, or it'll pop when heating or implode when cooling.
[21:40:12] <furrywolf> a 1/8" orifice or something is plenty
[21:41:50] <zeeshan> https://www.youtube.com/watch?v=fNuI6keQXYA
[21:42:36] <zeeshan> that looks scary to stand next to
[21:42:37] <zeeshan> but so bad ass!
[21:43:36] <furrywolf> so in addition to the heating elements, you have fluid loops somewhere in there?
[21:43:48] <zeeshan> yes
[21:43:57] <zeeshan> http://i.imgur.com/N1whRmt.png
[21:44:00] <zeeshan> you can see the fluid loop thingy there
[21:44:11] <furrywolf> I can't load images until the youtube video loads or I cancel it.
[21:44:18] <zeeshan> watch the video!
[21:44:19] <zeeshan> its cool
[21:44:32] <furrywolf> then it'll be 5+ minutes before I can load the image. heh.
[21:44:56] <RyanS> anyone done casting? aluminum, brass or iron
[21:47:47] <furrywolf> 350hp isn't that big... it's just very, very old.
[21:48:54] <furrywolf> so it lets the stator rotate, then brakes the stator, to avoid excessive startup currents?
[21:52:06] <furrywolf> the scary part is to work out the hoop stress in the stator. :P
[21:52:43] <zeeshan> its prolly stupid high
[21:52:49] <zeeshan> all the centrifugal "force"
[21:55:37] <furrywolf> think about all the copper and steel spinning...
[21:56:36] <Jymmm> IF you can do this, you get the job... https://www.youtube.com/watch?v=Q1CMSV81_ws
[21:58:20] <furrywolf> that's not that uncommon
