[03:42:30] <Deejay> moin
[06:12:57] <jthornton> morning
[08:30:48] <jthornton> so taking the desired arc length and calculating my central arc I can find the xy coordinate of the end point
[10:59:47] <JT-Shop> my download speed is worst than it used to be with dialup :(
[10:59:59] <Tom_itx> that's sad
[11:00:01] <JT-Shop> worse
[11:00:37] <JT-Shop> in any case I'm having fun with trig
[11:00:58] <Tom_itx> i dusted off SW last couple days
[11:01:01] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/rue/reprap/arcol_v4a.jpg
[11:01:23] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/rue/reprap/Test_thread.jpg
[11:01:29] <Tom_itx> did that just to see if i could
[11:01:39] <JT-Shop> I'd look but I'm trying to d/l mate desktop for debian
[11:01:50] <Tom_itx> duh
[11:01:57] <Tom_itx> you just commented on your dl speed
[11:02:17] <JT-Shop> yea, the d/l is going at 48 kB/s
[11:03:32] <Tom_itx> didn't you make a thread calc?
[11:03:38] <Tom_itx> with OD ID etc?
[11:03:41] <Tom_itx> PD
[11:03:43] <JT-Shop> yea
[11:03:49] <Tom_itx> for form threads?
[11:04:05] <JT-Shop> cut threads I assume
[11:04:26] <Tom_itx> yeah
[11:04:34] <Tom_itx> roll threads would be slightly smaller
[11:04:53] <JT-Shop> yea, roll and form threads are a different animal
[11:05:18] <Tom_itx> i call form threads: make it this size and run a die over it
[11:05:26] <Tom_itx> or singlepoint
[11:05:58] <JT-Shop> I call form threads when you tap with a forming tap
[11:07:10] <Tom_itx> point being, will your calc give me the OD for an OD die thread?
[11:07:50] <JT-Shop> if it is the same as cutting external threads on a lathe
[11:08:01] <Tom_itx> i don't see why not
[11:08:08] <Tom_itx> i'll take a look at it
[11:08:40] <JT-Shop> dunno, never looked up the OD for a threading die... I've only picked up a bunch of pipe and threaded it with a die
[11:09:51] <Tom_itx> it should be the same as single point since they're both removing material
[11:10:10] <JT-Shop> http://gnipsel.com/files/sfc/
[11:10:16] <JT-Shop> I think that is it
[11:10:31] <Tom_itx> ok
[11:10:46] <JT-Shop> let me go check that against the one in the beer cave
[11:10:54] <Tom_itx> no rush
[11:11:03] <Tom_itx> i'm not working on it today anyway
[11:11:49] <archivist> people often forget the tip rounding, inserts can cut the top properly on a lathe if you get the right ones
[11:13:15] <JT-Shop> my calculator does take tip radius into the calculations
[11:13:17] <archivist> been drawing parts of a clock pendulume in sw last few days
[11:13:29] <JT-Shop> neat
[11:14:39] * JT-Shop smells a nap looming
[11:16:00] <archivist> my mechanism had it missing, some I found in the wild http://www.collection.archivist.info/searchv13.php?searchstr=evans+tower
[11:17:22] <cathode> hmm if only i had a use for it. this seems like a good deal. http://portland.craigslist.org/clc/mat/4787612978.html
[11:17:51] <XXCoder1> pretty cheap
[11:18:04] <XXCoder1> isnt market at less than dollar per pound for alum for scrap?
[11:18:58] <cathode> i think so
[11:19:21] <cathode> like $0.60-0.75 / lb depending on how clean and how much you have
[11:19:23] <XXCoder1> wow window cover nut is over 10 bucks
[11:19:27] <XXCoder1> insane
[11:20:15] <cathode> eh?
[11:20:56] <XXCoder1> oh sorry, my van window is missing its holder nut and "washer". its really expensive
[11:21:46] <XXCoder1> http://www.ebay.com/itm/like/261482311820?lpid=82&chn=ps
[11:21:52] <XXCoder1> cheaper ebay but still
[11:24:29] <XXCoder1> anyway good find
[11:24:41] <XXCoder1> I dont need stuff like that yet though :)
[11:28:06] <cathode> heh
[11:28:09] <cathode> i wish i had a mill
[11:28:41] <cathode> my project for this summer (maybe) or next year is to build a 4-axis CNC vertical lathe/mill
[11:29:47] <XXCoder1> nice :)
[11:31:59] <cathode> essentially a 2 or 3 ft diameter turntable with jaws, and an overhead gantry
[11:32:18] <cathode> so for normal 3-axis milling i could just lock the turntable rotation
[11:32:33] <cathode> at least that's the idea i have in my head
[11:32:53] <Tom_itx> archivist, that clock almost appears to be on the backside of the building
[11:33:26] <archivist> Tom_itx, it is the inner wall behind the dial
[11:34:14] <archivist> we went to quote but never got the job, took pictures as it is the same make as mine
[11:34:14] <Tom_itx> the face seems obstructed by roofline
[11:35:09] <archivist> roof covers it from direct rain a bit
[11:35:45] <cathode> damn those are some huge bearings. http://www.ui-pi.com/userfiles/image/4.4%20Meter%20slewing%20bearing.jpg
[11:39:41] <XXCoder1> cat yeah
[12:15:19] <Tom_itx> pcw_home you around?
[12:42:39] <pcw_home> yes
[12:47:59] <Tom_itx> pcw_home, can i pm?
[12:48:56] <pcw_home> sure
[13:26:23] <furrywolf> argh, china... 20 handle turns is 3 inches. would it kill them to use rounder numbers? :)
[13:27:43] * furrywolf enters 6.666667tpi
[13:28:22] * Deejay suggests to use millimeters! ;)
[13:28:55] <moorbo> 76.2mm!
[13:28:57] <moorbo> even rounder.
[13:30:07] <moorbo> but yeah anything that isn't metric is bananas.
[13:30:32] <Deejay> ^^
[13:31:37] <pcw_home> 0.150" per turn is not too crazy
[13:32:13] * furrywolf enters 18.939394 microfurlongs per revolutions just to annoy moorbo
[13:33:44] <furrywolf> the microfurlong is a very underappreciated unit! look how well it specifies the pitch...
[13:35:26] <XXCoder1> foot pounds
[13:35:35] <XXCoder1> and pound-feet
[13:35:42] <XXCoder1> both has lots jokes
[13:39:11] <jdh> old vaxen had a time expressed in uFN
[13:39:26] <XXCoder1> anyone remember @time?
[13:41:49] <moorbo> furrywolf: I prefer using mini gerbal penises for measuring
[13:42:04] <moorbo> furrywolf: 15.465mgp
[13:42:08] <moorbo> :D
[13:42:20] * furrywolf needs a 42 tooth 1|5in timing pulley with 12mm bore. argh, mixing metric and imperial...
[13:42:39] <furrywolf> hrmm, I'm not sure zeta creations stocks one of those for me to use for measuring...
[13:43:06] <moorbo> probably not :(
[13:43:48] <moorbo> furrywolf: I assume you know http://theoatmeal.com/pl/senior_year/science
[13:44:46] <furrywolf> looks like they changed their name to zeta paws... but I don't see any gerbils. they have a mouse, though. however, at 9.5" long, it's most definitely not to scale, unless we're talking about mice from a '50s horror movie...
[13:50:06] <furrywolf> I should order something from zeta one of these days just to say I have...
[13:51:36] <XXCoder1> cubits :P
[13:53:56] <furrywolf> I like toys, but I prefer non-realistic... but I really should get something from them anyway.
[13:59:40] <furrywolf> so where do I find a 42xl037 with 12mm bore? bleh
[14:02:40] <furrywolf> seems imperial pitch pulleys with metric bores are hard to find... so I'll be stuck boring it myself, and I lack enough tooling... yay, an excuse to buy more tooling!
[14:04:24] <furrywolf> in related news, can we please round up and shoot every person who writes a website that scrapes ebay?
[14:43:40] <moorbo> furrywolf: do you have a stepper/servo with a 12mm shaft
[14:43:47] <moorbo> but using an imperial belt?
[14:46:04] <furrywolf> the leadscrews on my machine have 12mm ends.
[14:46:12] <furrywolf> I got the machine with five of the six pulleys... missing one.
[15:00:47] <furrywolf> yay, shopmaster still has replacement pullies.
[15:01:36] <furrywolf> they want $28 for it though... but it's probably easier than boring a cheaper one.
[15:34:03] <furrywolf> they also want $13/each for the timing belts... that seems a little steep to anyone else?
[15:34:47] <XXCoder1> dammit I cant find any guide on how to replace sparkplugs on my car
[15:35:09] <XXCoder1> common 2.0l v4 is everywhere. my car is rare v6 2.5l
[15:35:22] <XXCoder1> so instructions all are related to common version.
[15:37:39] <XXCoder1> See, as soon as I complain.. I find https://www.youtube.com/watch?v=hkdEc0pOaKs lol
[15:38:52] <XXCoder1> anyway football time laters
[15:38:55] <XXCoder1> seahawks!
[15:39:30] <furrywolf> xxcoder: ... guide on replacing spark plugs? remove old spark plugs. install new spark plugs.
[15:39:57] <furrywolf> remove anything in way, reinstallation is reverse of disassembly.
[15:52:31] <furrywolf> yeah, there's nothing in that video that needs a video.
[15:53:53] <furrywolf> if you want fun, do the rear bank on a voyager/caravan...
[16:03:04] <Deejay> gn8
[16:03:14] <zeeshan> bought another lathe
[16:03:14] <zeeshan> lol
[16:08:07] <zeeshan> http://i.ebayimg.com/00/s/ODAwWDYwMA==/z/qrUAAOSwwTlUoBP1/$_20.JPG
[16:10:17] <toastydeath> that looks like a fukin' baller lathe
[16:10:18] <toastydeath> just sayin
[16:10:24] <toastydeath> what brand, i can't read the plate
[16:10:30] <toastydeath> looks like a monarch pattern
[16:12:27] <zeeshan> monarch
[16:12:38] <zeeshan> you wont believe how much i paid for it
[16:12:44] <toastydeath> how much?
[16:13:34] <zeeshan> $300
[16:13:37] <zeeshan> its the monarch 14c
[16:14:07] <toastydeath> God dayum
[16:14:14] <zeeshan> he has a sodick
[16:14:15] <zeeshan> wire edm
[16:14:17] <zeeshan> $800
[16:14:21] <zeeshan> i wanted it, but i have no where to put it
[16:14:31] <zeeshan> its too tall for the garage shop
[16:14:55] <zeeshan> if anyone is interested in a wire edm for $800 in toronto area, lemme know, i can forward details
[16:18:01] <toastydeath> damn
[16:18:12] <furrywolf> sure, as long as you deliver it free to california area.
[17:02:33] <furrywolf> bbl, off to storage to yank the leadscrew.
[17:27:06] <jdh> whatever works foryou.
[18:22:33] <Jymmm> Loetmichel: Hey, do you use any 18650 vaps?
[18:35:55] <MrSunshine> hehe testing if a router bit is sitting in a collet by pulling on the bit by hand .. thats nice :P
[18:36:56] <MrSunshine> or cute ...
[19:04:25] <XXCoder1> victory!
[19:04:43] <furrywolf> leadscrew out... my torch tanks are empty, and I can't afford to refill them now, so I'll bug someone with a working torch tomorrow.
[19:06:20] <XXCoder1> furrywolf: not for me. im not mechinically inclined
[19:06:36] <XXCoder1> so yeah I needed video to see where sparkplugs are. my car is pretty rare
[19:06:46] <XXCoder1> not tucker or lamgani rare but yeah
[19:07:17] <furrywolf> eh... virtually all spark plug changes are a variation on remove anything in the way, remove spark plugs, install new spark plugs, re-install anything you took off the same way you took it off. :)
[19:07:17] <Tom_itx> follow the wires
[19:07:33] <XXCoder1> Tom_itx: cant, not with bigass airintake on way
[19:07:42] <Tom_itx> move it?
[19:08:02] <XXCoder1> ij least it looks easier than mecury sable lol now that was hardass
[19:08:25] <XXCoder1> tom too much work just for sparkplugs. LOTS parts just to remove that thing
[19:08:27] <furrywolf> there are some vehicles where the easiest way to change the spark plugs is to torch a couple access holes in the firewall. :)
[19:08:42] <XXCoder1> lol wish I did that. sable was hell
[19:08:54] <XXCoder1> 3.8l v6 which is huge engine in sedan
[19:09:59] <furrywolf> you don't need to change spark plugs in a sable/taurus. just do yourself a favor and crush them as soon as anything breaks. :)
[19:10:32] <XXCoder1> actually that sable was best car I ever owned. 9 years basically zero mainance
[19:10:44] <furrywolf> that has not been my experience.
[19:10:47] <XXCoder1> then some dumbf* did left turn without stopping to look and totaled it
[19:11:51] <furrywolf> suggestions on the best way to straighten a bent shaft? has about a 10 degree bend in it, with a ~1" radius, plus a very slight bend over a longer distance.
[19:12:08] <furrywolf> I was planning on getting it nice and hot and hammering it between two blocks of wood...
[19:12:26] <XXCoder1> you has good lengths of steel pipe?
[19:12:45] <XXCoder1> you could warm up the bend part and use one end secured pipe and other end you leverage
[19:13:23] <furrywolf> I thought of that, but figured it might create an indentation at the end of the pipe, and not bend smoothly over the entire bend.
[19:13:32] <furrywolf> sec, I'll grab a photo, if I can find my camera.
[19:14:13] <XXCoder1> good question, not sure what method would not cause indention.
[19:41:05] <zeeshan> https://www.flickr.com/photos/128539016@N05/16132598192/
[19:41:06] <zeeshan> hmm
[19:41:10] <zeeshan> crazy frame
[19:43:46] <Connor> zeeshan: What's it for ?
[19:45:39] <Tom_itx> wee bit overkill wouldn't you say?
[19:46:46] <zeeshan> connor to mount enclosure
[19:46:50] <zeeshan> i think i need to shorten the spacers
[19:46:52] <zeeshan> theyre too far out
[20:00:03] <zeeshan> has anyone power tapped larger threads
[20:00:07] <zeeshan> like 1/2" 3/4"
[20:00:10] <zeeshan> maybe even 1"
[20:00:18] <zeeshan> i guess anything above 1/2" can be thread milled
[20:00:21] <Tom_itx> why not?
[20:00:30] <zeeshan> i dunno, its a lotta force
[20:00:41] <Tom_itx> we used some that were propane bottle size
[20:00:48] <Tom_itx> to thread the connector
[20:00:58] <zeeshan> usually you use a hydraulic threading tool for that?
[20:01:19] <Tom_itx> just a regular reversing thread thingy
[20:01:31] <Tom_itx> lathe..
[20:01:46] <Tom_itx> 6 spindle lathe
[20:01:53] <zeeshan> when i use my drill chuck to hold the tap
[20:01:55] <zeeshan> it just spins
[20:01:56] <zeeshan> :P
[20:02:17] <Tom_itx> well maybe it wasn't meant to do that
[20:02:23] <zeeshan> i know
[20:02:23] <zeeshan> lol
[20:02:33] <zeeshan> i havent seen an off the shelf tap hold for a lathe
[20:09:03] <SpeedEvil> zeeshan: If it spins - loctite
[21:01:57] <zeeshan> anyone have a chart
[21:02:00] <zeeshan> for parting feedrate?
[21:02:16] <zeeshan> ipr ?
[21:10:13] <jdh> use the book
[21:10:22] <zeeshan> which book
[21:11:18] <jdh> Machinery's Handbook
[21:54:50] <Tom_itx> jdh, the bible of machinists :)
[21:56:16] <Tom_itx> zeeshan, you can download this also and put it on your smartphone: http://zero-divide.net/index.php?page=fswizard&shell_id=199&load_tool_id=27011
[22:10:17] <Computer_Barf> Connor: you around?
[22:11:34] <Computer_Barf> so im just starting to take stuff apart on my g0704 to do a cnc upgrade,
[22:11:38] <Computer_Barf> http://i.imgur.com/uNJ0XMc.png
[22:11:55] <Computer_Barf> took the endcap bolt off the z axis handle
[22:12:05] <Computer_Barf> then pulled on it a bit..
[22:12:12] <Computer_Barf> didn't slide off how i anticipated
[22:12:24] <Computer_Barf> wondered if I should apply a little more force..
[22:12:37] <Computer_Barf> then though.. humm ask internet
[22:12:44] <Computer_Barf> *thought
[22:21:40] <XXCoder1> I see notch at hole
[22:21:50] <XXCoder1> wonder if you need to align with pin inside or something
[22:22:33] <Computer_Barf> it does appear to have a keyway
[22:23:39] <Computer_Barf> https://www.youtube.com/watch?v=yY4zD-XRU6I
[22:24:01] <Computer_Barf> at 9:20 ish in this video he appears to be arriving the same issue
[22:25:29] <XXCoder1> guy removed the whole thing
[22:25:36] <Computer_Barf> yeah
[22:25:49] <Computer_Barf> gotta love youtube
[22:26:17] <XXCoder1> yep I recentl;y found solution on how to change sparkplugs on my car by youtube
[22:26:22] <XXCoder1> my car is quite rare
[22:26:54] <XXCoder1> not expecially rare but only 2% of cars is like mine (ignoring that my car is even rarer automatic version)
[22:27:32] <Computer_Barf> we have a smartcar that needs work , i wish ppl would put up videos on youtube
[22:27:47] <Computer_Barf> we had a mechanic that did some work and gave up
[22:28:00] <XXCoder1> whats wrong with it
[22:28:31] <Computer_Barf> he left one of the spark plugs out of it, but i basically can't put it back in without dropping the engine. smartcars have increidbly tight engine spaces
[22:28:59] <XXCoder1> lol reminds me of old mecury sable 1986 with 3.6l engine
[22:29:08] <XXCoder1> its 2 ton truck engine type in sedan
[22:29:11] <Computer_Barf> the thing overheated at some point, we had a guy machine the block
[22:30:15] <Computer_Barf> since we have other cars, im not in a rush to fix it, mostly using it as an oppertunity to try to learn about car engines
[22:30:17] <Computer_Barf> but im a noob
[22:30:50] <Computer_Barf> and ppl that helped so far, are spanish speaking so.. i don' have the best info on what exactly was done
[22:31:00] <Computer_Barf> basically two seperate guys worked on it
[22:31:28] <Computer_Barf> one guy did some machining and said mechanically it was ready but the electronics needed looking at
[22:31:48] <Computer_Barf> and the other guy gave up after draining the battery and leaving the spark plug out
[22:32:06] <Computer_Barf> so at that point im basically.. ok ill do this myself when i do it
[22:32:48] <Computer_Barf> it sounded like reboring the engine altered the compression ratios and thats probably why its not starting
[22:32:58] <Computer_Barf> but thats a guess based on second hand translations
[22:33:24] <Computer_Barf> i know it turns over
[22:33:50] <jdh> put a compression checker on it
[22:34:33] <jdh> if they were slightly overbored, oversize rings will work. else you need new pistons + rings
[22:35:33] <cradek> I predict you are missing compression, correctly-metered fuel, or correctly-timed spark :-)
[22:35:51] <cradek> next step is figure out which one it is
[22:35:52] <jdh> I agree
[22:35:54] <Computer_Barf> thanks.. Ive been watching videos on the basics of car engines, and how they work. I watched videos on diagnosing car engines and that was in the list of things. Sounds good to have someone else second it.
[22:36:40] <cradek> if the engine was apart it sure could be compression - incorrect rings, valve timing wrong, forgot the head gasket, who knows
[22:36:59] <cradek> don't assume anything
[22:37:53] <Computer_Barf> i know that the head gasket was replaced in the course of the first guys work
[22:38:29] <Computer_Barf> second guy essentially didn't do much. First guy did machining but essentially said now that mechanics are done , electronics ain't his thing.
[22:39:47] <Computer_Barf> which seemed, kind like he didn't want to take responsibility for his mechanical work but who knows. Fortunantly family friend so his payment pends ultimately on it running at some point.
[22:40:14] <cradek> overheating caused all this?
[22:40:23] <Computer_Barf> I really appreciate you guys input though, Im definantly taking notes
[22:41:10] <Computer_Barf> yes we were driving alone and the engine started running strange, I pulled over and we go out, fluid spilling out all under the car
[22:41:25] <cradek> overheating was probably not an electronics problem
[22:41:54] <Computer_Barf> i know that at some point, fumes were coming back up into the coolant
[22:41:59] <cradek> "I don't know what all I unplugged, so good luck"
[22:44:17] <Computer_Barf> yes.. I suspected this was the case, cause it seemed kind of bullshit to be separating out mechanical from electronics, when this same dude does odd jobs fixing electrical work.
[22:52:11] <furrywolf> pictures taken... got distracted helping neighbor with car work, then showered to get all the grease off me...
[22:52:42] <Computer_Barf> pictures taken of what?
[22:53:42] <furrywolf> I was asking earlier about straightening a bent shaft
[22:53:57] <Computer_Barf> damn
[22:54:00] <furrywolf> and one of these hours they'll finish uploading. $@#$@#ing crappy internet connection.
[22:54:02] <Computer_Barf> that can't be fun
[22:57:22] <furrywolf> still uploading... two jpegs...

[22:59:06] <furrywolf> I have a connection that can barely transfer two still images. I'm not watching videos. :P

[23:00:37] <Computer_Barf> YOWCH!
[23:00:46] <CaptHindsight> go to town with a rubber mallet and sand box
[23:01:04] <furrywolf> I was thinking a torch, a couple blocks of wood, and something a lot heavier than a rubber mallet...
[23:01:22] <furrywolf> heat red, put on one block, beat with hammer and second block...
[23:01:47] <CaptHindsight> it doesn't look heated
[23:01:57] <furrywolf> yet. :P
[23:02:12] <Computer_Barf> is that off a cnc?
[23:02:19] <furrywolf> yes
[23:02:31] <Computer_Barf> how did this happen?
[23:03:02] <furrywolf> several owners ago, either the machine fell or got hit with a forklift or something... the story wasn't too clear.
[23:03:30] <CaptHindsight> you need a much larger screw to be forklift proof
[23:04:10] <furrywolf> that's the end the timing pulley goes on. the other end has the manual handwheel. they cut out a big hole to let the shaft wobble around and used it as a manual mill.
[23:05:33] <furrywolf> it has the sharp bend at the end, and a gentle bend in the opposite direction (not just camera distortion). I couldn't find any bend in the threaded portion, either with a straightedge or watching for runout on the machine.
[23:06:36] <furrywolf> I'd like to do it without heat, but I'm worried it'll crack if I just stuff it in the press...
[23:13:24] <cradek> not much of a cnc if it doesn't have ballscrews
[23:13:31] <cradek> are you sure it's worth fixing?
[23:13:35] <furrywolf> it's a cnc that's within my budget.
[23:13:42] <furrywolf> and fixing it will likely cost under $1.
[23:14:01] <furrywolf> nothing with ballscrews is anywhere near my budget.
[23:14:24] <cradek> how about chop it off, turn it down, press/shrink fit an extension
[23:14:59] <cradek> if there's clearance you could shrink an extension to the outside of this original diameter, and not have to heat the screw at all
[23:15:32] <furrywolf> chop and extend is plan B, if it breaks during plan A.
[23:16:22] <cradek> I guess I've unbent some surprising things, like pushrods
[23:16:31] <furrywolf> I wouldn't even bother with shrink fit, just sleeve and weld...
[23:16:35] <cradek> all you need is patience and a surface plate to roll it on and observe
[23:16:47] <cradek> weld!?
[23:16:55] <cradek> I thought the point was to have it straight when done
[23:17:04] <renesis> very tiny welder
[23:17:06] <furrywolf> and then adjust with a hammer. :P
[23:17:28] <furrywolf> the way the machine is built, I can live with a couple thous runout. I can't, however, live with an 8 degree bend. :)
[23:17:32] <cradek> have you ever ... seen welding? haha
[23:18:12] <furrywolf> I can weld 225A continuous duty with my lincoln... 300A intermittant if I dig the big Miller out of storage...
[23:18:15] <cradek> but yeah you're right, if it's a sloppy screw in sloppy bronze nuts it doesn't have to be very straight
[23:18:22] <furrywolf> I'd probably use my little 110V MIG, however.
[23:18:50] <furrywolf> I have a miller wire feeder that plugs into the 300A supply, so I can do big mig... but the little mig is much more suitable for a 12mm shaft. heh.
[23:20:02] <furrywolf> the bracket that holds the nuts can flex in the runout direction easily... it can take a _lot_ of runout with no problems. and the other end is a timing belt, which again can absorb a lot of runout. that said, a hammer is very good at slight adjustments.
[23:22:06] <furrywolf> I could also join it with a flexible shaft coupler and add a second bearing
[23:22:28] <renesis> silly putty
[23:22:38] <renesis> or play-doh
[23:22:48] <furrywolf> ?
[23:22:49] <renesis> play-doh is structural if you let it dry out
[23:24:00] <furrywolf> the big question is whether I press it cold or hot...
[23:27:01] <furrywolf> cradek: a good weld is just as strong as the original material. a standard test of welding skill is to butt weld two bars together and grind the joint smooth, then bend them 180 degrees. if you're competent, you won't be able to see where your weld was, as it flexes the same as the rest of the bars, without cracking. people more skilled than I am can do really impressive things, like tig weld soda cans. :P
[23:31:14] <renesis> i think cradek was concerned about the heat warping near the weld, not the strength
[23:31:27] <renesis> just guessing tho
[23:31:53] <furrywolf> stitch weld, weld and anneal, or go all the way around in one pass and let it cool evenly...
[23:32:01] <furrywolf> and then adjust with a hammer. :)
[23:46:40] * furrywolf suspects welders and machinists have long-standing issues with each other over tolerances and methods of improving them...
[23:48:52] <furrywolf> bbl, wolfy bedtime
[23:52:09] <XXCoder1> howl
[23:52:28] <furrywolf> http://www.ebay.com/itm/NEW-SAMSU-840-EVO-1TB-2-5-SSD-MZ-7TE1T0BW-SOLI-STATE-DRIVE-/231435823528?pt=US_Dolls&hash=item35e2a669a8 think buying that actually results in a drive showing up? I'm leaning towards "no".

[23:53:11] <XXCoder1> probably a very nice drive
[23:53:19] <XXCoder1> err
[23:53:23] <XXCoder1> I meant drive box lol
[23:53:29] <furrywolf> lol
[23:53:45] <XXCoder1> was joking but forgot to finish with box :P
[23:54:30] <XXCoder1> 75 feedbacks
[23:54:39] <XXCoder1> only 4 shown
[23:55:05] <XXCoder1> "Gfhfjhbjkghkhgjgjfggghhhjjjjjhgghhhgfddfxddcfgh"
[23:55:08] <cathode> lol
[23:55:44] <XXCoder1> I wouldn't touch it with insulated 100 feet robot-operated tong
[23:56:13] <XXCoder1> but then maybe ikt's strange but legit
[23:56:30] <furrywolf> ten of them? :P
[23:56:44] <furrywolf> if they exist, probably stolen...
[23:57:03] <XXCoder1> use the correct code word: "it fell from back of truck"
[23:58:55] * LeelooMinai notes interesting category it's listed under:p
[23:59:11] <furrywolf> I got something once that really did fall off a truck! I found a big jar of 3m crimp connectors in the ditch by where the phone company was working once...
[23:59:30] <XXCoder1> clothe your computer with barbie hard drive :P
