[00:00:33] <PetefromTn_> cool engine turned
[00:00:44] <Valen> engine turned?
[00:01:25] <PetefromTn_> looks like engine turning too unless it was master scraped. Looks too uniform to me
[00:02:39] <PetefromTn_> never seen one like that before
[00:03:49] <PetefromTn_> does not look that hard to make. but grinding it is gonna be imperative
[00:05:22] <PetefromTn_> well gotta get to bed here. Cya guys tomorrow
[01:38:51] <archivist> that is spotted in a drill/mill not engine turned
[02:00:26] <archivist> http://www.circuitousroot.com/artifice/machine-shop/surface-finishing/spotting/index.html
[04:28:09] <toastydeath> apparently today is "guess at the correct answer" day in homebrew cnc world
[05:36:01] * Loetmichel has just mopped up a few liters of water+ car antifreeze. *note to self*: next time deactivate the pump before trying to clean out the gunk on the spindle watercooling system by pressing 8 bar compressed air into the coolers outlet (open circuit)
[05:36:14] <XXCoder> lol
[05:38:05] <Loetmichel> pumüp end of the hose popped of
[05:38:12] <Loetmichel> with running pump ;-(
[05:41:47] <Loetmichel> ... and the PC right above the pump outlet
[05:41:52] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14148&g2_imageViewsIndex=1
[05:42:22] <Loetmichel> the (cut open) plastic can on the lowes shelve houses the (indor well) pump
[05:42:41] <XXCoder> sigh gonna get my router cnc working
[05:50:58] <Loetmichel> s/well/fountain
[06:16:50] <Jymmm> Why is the workbench always the hardest thing to clean up
[06:18:35] <XXCoder> it hates you thats why
[06:18:36] <XXCoder> heh
[06:18:42] <Tom_itx> it should never be clean
[06:18:58] <Jymmm> Tom_itx: Now THAT I can believe
[06:19:12] <Jymmm> A clean desk/workbench is a sign of a sick mind!
[06:19:54] <Tom_itx> you must have at least 2 or 3 projects shoved aside on them at all times
[06:20:05] <Jymmm> But... I need to pack it all up and put into boxes
[06:20:18] <XXCoder> if cluttered table is sign of cluttered mind, whats sign of empty table?
[06:21:00] <Tom_itx> sorta like cleaning up a HDD. you know you should but you just can't
[06:21:32] <Jymmm> I have almost the rest of the garage packed, if I can get the workbech cleared I'll be golden!
[06:21:43] <Tom_itx> moving?
[06:21:56] <Jymmm> Hopefully =)
[06:22:05] <Jymmm> Waiting for escrow to close
[06:24:35] <Jymmm> I did a BAD thing
[06:24:43] <Jymmm> I tapped a vent hole on my 5 gal plastic gas cans, emptied them into my SUV, then plugged the vent hole with a bolt.
[06:24:53] <Jymmm> (I'll get REAL vent caps for it later)
[06:25:37] <jthornton> you can get fix it kits for gas cans that include the snap in vent
[06:25:54] <Jymmm> jthornton: These http://www.ebay.com/itm/10-Yellow-VENT-CAPS-Gas-Fuel-Can-Midwest-Blitz-Wedco-Briggs-Scepter-HEAVY-DUTY-/360657081144
[06:26:40] <jthornton> that's even better
[06:27:02] <Jymmm> jthornton: In Calif, we have this "CARB Compliance" bullshit that does NOT permit those type of vents, but phuk em.
[06:28:21] <Jymmm> jthornton: Spring loaded spouts that barely work and take 12 hands to open while holding up 5gallons of gas
[06:28:34] <jthornton> http://www.amazon.com/Replacement-Spout-Water-Update-Your/dp/B00CYNDNM8/ref=sr_1_4?ie=UTF8&qid=1435921492&sr=8-4&keywords=gas+can+vent+caps
[06:28:58] <jthornton> yea the gas cans have become stupid and cumbersome
[06:30:18] <Jymmm> I had been scouring the flea market for pre-CARB Complaince cans for a while
[06:30:53] <Jymmm> That 8" extension will come in handy jthornton, thanks.
[06:32:17] <Jymmm> I had to leave 1/2 gal in the can because the spout was too short
[06:33:48] <Jymmm> jthornton: The spout you linked me to (gas,not water version, even thought the same damn thing) "Due to (CARB) California Air Resources Board regulations, this product is banned for sale in the following states: CA"
[06:34:37] <jthornton> you need to find someone to smuggle them in for you
[06:35:35] <Jymmm> jthornton: Heh, I need to smuggle a LOT of things into Kommifornia. Spouts, generator, magzines
[06:36:43] <Jymmm> jthornton: I love the description "White Or Black Kits Have Identical Parts And Vary Only In Color And Packaging" (hint hint nudge nudge)
[07:03:29] <malcom2073> Jymmm: Or smuggle yourself out
[07:09:22] <Jymmm> malcom2073: Oh NOW you tell me! Too late now, we'll be the owner of a mortgage in a few days
[07:09:30] <malcom2073> Haha whups
[07:15:29] <Jymmm> Man, the crap we gather adds up over the years.
[07:15:47] <Jymmm> Where in the hell did all this come from?!?!?!
[07:22:07] <archivist_herron> mortgage company owns you
[07:22:39] <Jymmm> True, but it'll be worth it =)
[07:23:10] <archivist_herron> rent is never worth it
[07:23:26] <Jymmm> No more "rent". No more slum lord.
[07:31:28] <archivist_herron> over here the landlords charge enough to pay their own mortgage and make a profit
[07:33:04] <Jymmm> and you can never get ahead
[07:34:55] <malcom2073> Someday Iwant to do that, buy a house, rent it otu and get the renters to pay the mortgage heh
[07:36:43] <malcom2073> There's a market: Make injection moulded pre-carb style screw tops that fit on new style gas cans
[07:53:45] <Loetmichel> [12:56] <Jymmm> A clean desk/workbench is a sign of a sick mind! <- so i am VERY sane, arent i? http://www.cyrom.org/palbum/main.php?g2_itemId=15341&g2_imageViewsIndex=1
[07:58:07] <Jymmm> Loetmichel: lol
[07:58:23] <Loetmichel> ... yes, thats my workbench at the company
[07:58:44] <Jymmm> Loetmichel: I can actually SEE workbench there
[07:59:10] <Loetmichel> yeah, some spots are still visible #,)
[07:59:15] <Loetmichel> :-)
[08:00:03] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14538&g2_imageViewsIndex=1
[08:00:06] <Loetmichel> hows that?
[08:08:24] <archivist_herron> far too tidy
[08:11:12] <malcom2073> Ohhh, so it seems my servo amps have differential input, so I can likely run them very low speed off two 0-5v analog signals, rather than -10/+10. Sounds like I can do some motion tests!
[08:12:53] * Loetmichel just warapped half a square meter of 1,5mm thick sheet aluminium around a beamer ;-)
[08:13:58] <malcom2073> What's a beamer?
[08:14:37] <Loetmichel> video projector, sorry
[08:14:52] <Loetmichel> in german its called a "beamer"
[08:17:22] <malcom2073> Ah cool, making an enclosure?
[08:17:58] <Loetmichel> yes
[08:19:00] <Loetmichel> botched the first try, the second fits like a glove: http://www.cyrom.org/palbum/main.php?g2_itemId=15862&g2_imageViewsIndex=1
[08:19:11] <DaViruz> almost a little silly to shield something that is designed to display its
[08:19:13] <Loetmichel> (first try parts in the BG)
[08:19:16] <DaViruz> input as openly as possible..
[08:19:17] <DaViruz> :)
[08:19:54] <Loetmichel> yes, that was my thought, too
[08:20:13] <Loetmichel> @daviruz
[08:20:34] <Loetmichel> but you know, customer wihses, customer gets ;-)
[08:20:38] <malcom2073> Oh nice
[08:20:47] <DaViruz> though it does look it make super rugged and professional :)
[08:20:55] <DaViruz> does make it look*
[08:21:16] <malcom2073> indeed, looks much more expensive than when it was covered in plastic I'm sure :-P
[08:21:37] <Loetmichel> it IS more expensive
[08:21:43] <malcom2073> Haha yeah
[08:21:46] <malcom2073> Laser cut?
[08:21:49] <Loetmichel> thats the third day we are working on that
[08:21:51] <Loetmichel> 2 ppl
[08:22:05] <Loetmichel> so you can imagine the invoice to the cuistomer ;-9
[08:22:10] <malcom2073> Hah yeah
[08:22:12] <Loetmichel> CNC milled
[08:22:33] <malcom2073> Really? How'd you the sheet metal?
[08:22:42] <malcom2073> fixture*
[08:22:51] <malcom2073> Totally lost that word there somehow....
[08:23:16] <Loetmichel> that way: http://www.cyrom.org/palbum/main.php?g2_itemId=14682
[08:23:26] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14685
[08:23:32] <malcom2073> ahhh heh
[08:23:32] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14688
[08:23:33] <malcom2073> nice
[08:23:52] <malcom2073> So how does that work with the larger holes?
[08:24:09] <Loetmichel> int the vacuum bed?
[08:24:12] <malcom2073> yeah
[08:24:18] <Loetmichel> the holes are double diameter
[08:24:22] <malcom2073> I mean when you're cutting larger holes
[08:24:53] <Loetmichel> 1/8" all the way down near the bottom of the platem, then 0,01" thru
[08:25:07] <Loetmichel> i simply miill them with a 2mm mill bit
[08:25:26] <malcom2073> Oh, so the left over metal seals the hole, and you only have a 2mm width circle for air to leak through
[08:25:28] <malcom2073> ?
[08:27:07] <Loetmichel> https://www.youtube.com/watch?v=BWTTP0RomA0
[08:27:12] <Loetmichel> grr
[08:27:15] <Loetmichel> worng link
[08:27:18] <Loetmichel> above
[08:27:34] <malcom2073> Ohhhhh, the cover plate has tiny holes, I got it
[08:27:44] <malcom2073> And you just seal off the rest with more plates, makes sense
[08:27:50] <malcom2073> <- Never done anything vacuume
[08:27:54] <Loetmichel> yes
[08:28:01] <malcom2073> I like that setup
[08:28:47] <Loetmichel> and because its made on the machine you can simply put a new cover plate on and set the mache to do anotehr 3000 holes when the cover plate is worn down
[08:29:20] <malcom2073> Smart
[08:30:33] <Loetmichel> btw: thast just an shopvac generating that vacuum
[08:30:43] <Loetmichel> no expensivem vacuum pump
[08:30:50] <malcom2073> Nice
[08:30:58] <Loetmichel> but you have to have one with "bypass cooling"
[08:31:10] <malcom2073> Ah yeah, I've heard about that, to avoid burning it out
[08:31:15] <Loetmichel> so it doesent overheat when basically choked
[09:26:17] <DaViruz> Loetmichel: do you ever do double sided machining om your enclosures?
[09:26:31] <DaViruz> i'm thinking then need to be bent both ways sometimes
[09:50:27] <Loetmichel> DaViruz: i do
[09:50:29] <Loetmichel> sometiomes
[09:51:01] <Loetmichel> but that involves macining one side, drilling some holesthruu excess sheet AND the waste board and thenm fliping it
[09:51:12] <Loetmichel> so it costs some
[10:04:06] <dirty_d> it works http://imgur.com/f2ITqal,XhjHudg,4pUmiOy,N0dma9N,ckeQCln#3
[10:13:00] <furrywolf> it works, and it is a....?
[10:14:06] <archivist> vernier caliper
[10:14:44] <dirty_d> peltier beer cooling glass
[10:14:46] <dirty_d> thing
[10:15:35] <furrywolf> ah.
[10:15:43] <furrywolf> what holds the upper o-ring down?
[10:15:46] <archivist> I just switched off my peltier junk and gone back to a real fridge
[10:16:14] <dirty_d> larger OD http://i.imgur.com/wPERLyD.jpg
[10:16:27] <furrywolf> and is that alu?
[10:16:58] <furrywolf> and where's the li-ion battery pack and cooling fan to make it portable? :)
[10:17:23] <dirty_d> yup, not done, just trying it out
[10:17:24] <dirty_d> brb
[10:17:42] <Deejay> moin
[10:17:58] * furrywolf thinks deejay slept in
[10:18:51] <redlegion> Advanced beer conditioning systems, for the discerning natural ice enthusiast
[10:19:02] <redlegion> Lulé
[10:19:26] * furrywolf doesn't drink, so doesn't know much about the finer details of beer cooling
[10:19:54] <redlegion> furrywolf, you underage or just surpassingly lacking reasons to drink?
[10:20:07] <redlegion> I have kids, beer is non optional
[10:21:57] <furrywolf> I'm underage for getting too many aarp fliers, does that count? :P
[10:23:44] <furrywolf> why would I want to do something that costs money, makes you stupid, feels stupid, hurts your health, and makes you feel poorly later too?
[10:23:51] * furrywolf has never understood why anyone, ever, would drink
[10:24:15] <malcom2073> Not to mention doesn't taste good
[10:24:31] <malcom2073> http://www.xkcd.com/1534/
[10:24:33] <malcom2073> :P
[10:24:50] <malcom2073> erm I mean
[10:24:53] <malcom2073> that is DELICIOUS!
[10:25:28] <furrywolf> yep, and tastes like crap.
[10:28:10] <furrywolf> utterly unpleasant experience from the time you get your wallet out.
[11:47:48] <PetefromTn_> well I just received my DC power supply for the anodizing station setup.
[11:48:05] <PetefromTn_> a quick check with a voltmeter shows it at least seems to be working so that is good.
[11:49:08] <PetefromTn_> going to try setting this thing up beginning of the week once the rest of the stuff I ordered arrives.
[12:03:09] <Tom_itx> are you building some hanging racks for the parts too?
[12:08:58] <PetefromTn_> yeah I plan to
[12:09:47] <PetefromTn_> I have some aluminum scrap that would work good for that
[12:13:02] <PetefromTn_> this power supply is actually nicer than I expected for the price
[12:13:26] <PetefromTn_> it is really heavy little bastard and the knobs and controls seem well made for something chinese anyway
[12:15:26] <archivist> many amps?
[12:15:44] <PetefromTn_> ?
[12:17:10] <archivist> when I were a lad, anodising was set up in amps per square meter, so you need lots for large vats :)
[12:17:23] <PetefromTn_> this is a 10 amp unit
[12:19:20] <archivist> 40 years since I worked at an anodising/electropaint place, cant remember the actual numbers
[12:23:22] <PetefromTn_> well as I understand it which is very little so far the higher the current the faster the process goes up to a point of burning the part. You can certainly do it with less current it just takes more time.
[12:26:02] <archivist> one of those jobs engrained in the brain for the wrong reasons, like the freezing cold journeys to get into work
[12:26:57] <PetefromTn_> that does not sound like fun
[12:27:15] <PetefromTn_> I am hoping to get some money and at least SOME enjoyment from this process ;)
[12:27:49] <PetefromTn_> I think just the cool colors and splash anodizing will be enjoyment enough for me.
[12:27:58] <archivist> and the atmosphere one breaths in, sulphuric and caustic, never caught a cold while working there though
[12:28:24] <Tom_itx> probably caught something else
[12:28:46] <PetefromTn_> well as said before I plan to do the nasty shit outside
[12:29:34] <PetefromTn_> you know so my neighbors can enjoy it too
[12:29:38] <PetefromTn_> hehe
[12:29:46] <Tom_itx> weed control
[12:30:02] <PetefromTn_> Hey that is a nice side effect. I hate weeds
[12:30:36] <archivist> carrying a new bag of caustic one day I could feel the odd stinging sensation through clothes
[12:31:03] <PetefromTn_> jeez is it really that bad?
[12:31:12] <Tom_itx> it's not good
[12:31:27] <Tom_itx> got rubber gloves?
[12:31:28] <PetefromTn_> I have watched TONS of anodizing videos and most of the time people are not even wearing PPE...
[12:31:32] <Tom_itx> rubber apron?
[12:31:57] <PetefromTn_> that guy John Grimsmo does it INSIDE the shop and never seems to wear anything protective in the vids
[12:31:58] <archivist> in those days not a lot of ppe was provided at all
[12:32:13] <Tom_itx> well he's just not that bright then ehh?
[12:32:18] <archivist> you do get used to it
[12:32:32] <PetefromTn_> apparently
[12:33:05] <archivist> after a while you dont notice it, the lungs seem to get used to the effects
[12:33:19] <PetefromTn_> LOL not my lungs
[12:33:29] <PetefromTn_> I plan to wear a respirator the whole time
[12:33:38] <PetefromTn_> even with it outside
[12:34:06] <PetefromTn_> I am actually quite used to that and it does not bother me from YEARS of spraying finishes on cabinetry
[12:34:28] <furrywolf> I got used to being bitten by black windows.
[12:34:31] <PetefromTn_> a good quality respirator is not all that uncomfortable anyways
[12:34:41] <furrywolf> one of the many perks of running cables for a living...
[12:34:48] <Tom_itx> the respirators didn't do much for the strippers i used to use
[12:34:58] <PetefromTn_> really?
[12:35:05] <PetefromTn_> WTF kind of strippers did you use?
[12:35:16] <furrywolf> good ones. :)
[12:35:18] <Tom_itx> came in a 30gal barrel
[12:35:32] <PetefromTn_> I use that mar hyde tal strip shtuff
[12:35:37] <PetefromTn_> works awesome
[12:35:43] <PetefromTn_> burns skin on contact
[12:35:48] <Tom_itx> used an old bathtub with a pump with it
[12:35:55] <PetefromTn_> can't even smell anything with respirator on
[12:36:45] <Tom_itx> at one point i had a brass strainer on the intake but it ate that up
[12:37:26] <PetefromTn_> anyways I plan to be careful :D
[12:37:43] <PetefromTn_> and I plan to make some really cool shtuff with it
[12:38:04] <PetefromTn_> hopefully it will both make my parts more durable and cool looking
[12:38:26] <archivist> ex boss over did a bath of aqua regia and we had some rust on the lathes next day
[12:38:29] <PetefromTn_> even if all I do is get this particular job finished and anodized successfully it will be worth the price of admission
[12:39:59] <archivist> he used to put his fingers in it to get the brass items back out
[12:40:44] <furrywolf> "do not put remaining fingers into vat"
[12:41:10] <archivist> only used it dilute to brighten brass castings
[12:41:27] <PetefromTn_> speaking of brightening
[12:41:48] <PetefromTn_> When I was on Casewells website ordering some stuff they have a product for aluminum brightening
[12:42:19] <archivist> caustic under a trade name?
[12:42:21] <PetefromTn_> apparently it is not a polish
[12:42:40] <PetefromTn_> it is apparenlty removing a slight bit of material from the surface
[12:42:55] <archivist> look at the safety sheet to see what is in it
[12:43:14] <PetefromTn_> http://www.caswellplating.com/anodizing-products/anodizing-accessories/aluminox-environmentally-safe-aluminum-brightener.html
[12:43:29] <archivist> same as first step of anodising, strip
[12:44:33] <furrywolf> hrmm, I put up a load of laundry because the sun was out, and now the sun has been replaced by black clouds.
[12:44:36] <PetefromTn_> not sure what I would need it for
[12:45:44] <furrywolf> you can clean up customer's car parts...
[12:47:58] <archivist> PetefromTn_, sulphuric,phosphoric and hydroflouric acids
[12:48:17] <greg__> yum
[12:48:19] <PetefromTn_> huh?
[12:48:31] <greg__> in your caswell brightner
[12:48:41] <PetefromTn_> jeez
[12:48:45] <PetefromTn_> nasty shite
[12:49:09] <archivist> http://www.collection.archivist.info/archive/mirror/aluminox/
[12:49:46] <archivist> safety sheets are wonderful for industrial espionage
[12:49:57] <greg__> yeah I've read many
[12:50:21] <PetefromTn_> damn that is some powerful stuff apparently
[12:50:23] <archivist> I guess the ehylenexxxx is a detergent
[12:50:33] <PetefromTn_> they talk about it like you can polish diamond plate with it
[12:50:38] <archivist> nah tiny percentages
[12:51:13] <archivist> ish, has a bit of bite :)
[12:51:48] <PetefromTn_> well if I can find a reason to have it maybe I will order some
[12:52:38] <archivist> I like having a selection of cleaners so I can select the best for a job
[12:52:57] <PetefromTn_> sure
[12:53:04] <PetefromTn_> I have quite a collection already
[12:58:31] <furrywolf> looks like the weather is going to get darker before it gets brighter... bleh. I should have checked the weather forecast BEFORE starting a load of laundry.
[12:59:14] <PetefromTn_> its been raining here for three days
[12:59:47] <PetefromTn_> supposed to rain for the fourth tomorrow too apparently but they are saying it may clear up before the afternoon
[13:00:21] <PetefromTn_> I was planning on buying all my high explosives for the celebration but after hearing the forecast I did not. Maybe I should go and do it today....Hm
[13:01:29] <furrywolf> I think I'll burn the oil out of the muffler on my eu1000i by using it to run the dryer. :)
[13:03:23] <malcom2073> Is it possible to anneal used resistive heating wire, such as Kanthal (MoSi2) or Nichrome? Can't seem to find much information, other than the ability to purchase pre-annealed or non new
[13:26:46] <furrywolf> my Outback inverter is doing a surprisingly good job doing generator support. I have the generator current limit set to 5A. when the dryer kicks in, it draws a lot more than 5A. the generator loads up, but the inverter picks up the rest of the load before the generator goes into overload mode of the voltage dips enough for the inverter to reject it.
[13:27:04] <furrywolf> s/of the/or then
[13:27:05] <furrywolf> or then
[13:27:07] <furrywolf> grrrr
[13:27:08] <furrywolf> or the
[13:55:47] <furrywolf> aerospace solar cells are really light... I wonder how thick of a column of hydrogen is needed to float one?
[13:56:27] <furrywolf> build a huge massive blimp covered in solar cells with a tether back to earth, so it can stay above all this stupid weather.
[14:01:27] <furrywolf> meh! rain just started.
[14:07:31] <dirty_d> the rod i used to cut the fins on that rod wasnt tool steel
[14:07:35] <dirty_d> it was kinda scary
[14:07:45] <dirty_d> horrible noises
[14:08:16] <furrywolf> lol
[14:08:22] <furrywolf> wear safety glasses.
[14:09:10] <dirty_d> always, lol
[14:09:36] <dirty_d> i had to hit stop on the last one because the steel got so hot it deformed and stopped cutting
[14:10:19] <dirty_d> how are you actually supposed to thread something like this? http://i.imgur.com/J11QbAL.jpg
[14:10:35] <dirty_d> i just put it loose in the chuck to keep it aligned
[14:11:15] <furrywolf> with a lathe. :P
[14:11:33] <dirty_d> here is my lathe https://www.youtube.com/watch?v=AlngHQy9b1I
[14:11:34] <Tom_itx> wtf
[14:11:39] <furrywolf> (with a die holder in the tailstock)
[14:11:43] <dirty_d> ground a drill bit
[14:12:55] <dirty_d> didnt have any more crappy ones to grind the fin cutter tool thing
[14:14:34] <Tom_itx> what's wrong with this picture? http://i.imgur.com/J11QbAL.jpg
[14:14:53] <furrywolf> a lot?
[14:15:34] <dirty_d> im not actually spinning that, lol
[14:15:45] <dirty_d> the chuck is just keeping the rod straight
[14:15:49] <dirty_d> and im turning it by hand
[14:16:17] <Tom_itx> you don't own a die holder?
[14:16:24] <dirty_d> nope, lol
[14:17:04] <dirty_d> would you be able to cut that with a die holder straight by hand?
[14:17:20] <Tom_itx> why not?
[14:17:48] <dirty_d> i dunno, when i tried threading holes by hand the tap didnt want to go in straight
[14:17:53] <dirty_d> so i figured id have the same problem here
[14:18:02] <Tom_itx> who's guiding whom?
[14:18:09] <Tom_itx> the tap or the operator?
[14:18:21] <dirty_d> little from column A, little from column B
[14:18:37] <Tom_itx> i have been known to put taps in the press for a certain straight thread
[14:18:41] <furrywolf> http://www.ebay.com/itm/ATLAS-LATHE-SOUTHBEND-TAIL-STOCK-1-INCH-DIE-HOLDER-/271916766490
[14:19:27] <dirty_d> i dont have a lathe though
[14:19:54] <furrywolf> you pasted a link with the description "here is my lathe"...
[14:20:11] <dirty_d> oh i was joking, thats just my mill with the work in the spindle
[14:20:20] <furrywolf> ah
[14:20:31] * furrywolf usually ignores youtube links
[14:21:17] <furrywolf> ebay description of the day:
[14:21:17] <furrywolf> “Used but brand new never used”
[14:21:24] <dirty_d> lol
[14:22:03] <furrywolf> http://www.ebay.com/itm/1-2-28-HSS-die-and-tailstock-die-holder-/111703484291 on that listing
[14:23:17] <dirty_d> why the hell dont they make 4.5" angle grinders with a trigger like the bigger ones?
[14:23:19] <furrywolf> this little eu1000i seems to be doing its job... I've been running it at 950W non-stop.
[14:23:29] <dirty_d> did you get it shiny?
[14:23:30] <furrywolf> ... they do?
[14:23:45] <furrywolf> all I had to do was wash this one. it didn't need extra shinying.
[14:23:50] <dirty_d> furrywolf, all ive seen are the ones with a paddle with a safety
[14:24:17] <furrywolf> I had one I got for $20 at a local hardware store that had a squeeze-type trigger... random chinese brand.
[14:24:22] <dirty_d> like this? http://www.ebay.com/itm/Makita-7-Trigger-Switch-15-Amp-Angle-Grinder-GA7021-RECON-/281711630985?pt=LH_DefaultDomain_0&hash=item4197525a89
[14:24:33] <furrywolf> worked for about a year until the motor burnt out.
[14:24:54] <Tom_itx> it outlasted it's warranty
[14:25:04] <furrywolf> http://www.correctcraftfan.com/forum/uploads/9590/angle_grinder.jpg looks like Ryobi makes one that style too
[14:25:27] <dirty_d> oh nice
[14:25:59] <furrywolf> I don't remember what random chinese brand mine was. it was blue. lol
[14:26:05] <dirty_d> hmmmm.... http://www.amazon.com/Kawasaki-841428-2-Inch-7-5-Amp-Grinder/dp/B008PN5K72/ref=sr_1_14?s=power-hand-tools&ie=UTF8&qid=1435950131&sr=1-14&keywords=angle+grinder
[14:26:44] <dirty_d> variable speed too, but its only $36
[14:27:24] <furrywolf> http://www.alibaba.com/product-detail/DB5016-115MM-125MM-4-5-5_227336046.html there's another one, straight from china...
[14:28:51] <furrywolf> the dewalt cordless one is on my list of tools to pick up when I have spare money and/or find cheap at a yard sale.
[14:30:14] <furrywolf> http://www.menards.com/main/tools-hardware/power-tools-accessories/grinders/stanley-reg-fatmax-reg-4-1-2-paddle-grip-angle-grinder/p-2229453.htm looks like staney makes one too, but it looks a bit uncomfortable...
[14:31:35] <dirty_d> yea i dont know why they put the trigger so far forward
[14:32:02] <dirty_d> lot of reviews saying that kawasaki one is very underpowered
[14:32:40] <furrywolf> kawasaki-branded tools are the crappiest of the chinese crap
[14:33:10] <furrywolf> usually worse than harbor freight
[14:33:20] <dirty_d> i wouldnt think that was possible
[14:34:39] <dirty_d> hmmm http://www.ebay.com/itm/DPST-Momentary-Control-Electric-Power-Tool-Trigger-Switch-AC250V-10A-/231326188561?pt=LH_DefaultDomain_0&hash=item35dc1d8411
[14:34:41] <furrywolf> harbor freight has a warranty you can actually use, so they can't make it break TOO quickly...
[14:35:16] <dirty_d> yea thats true
[14:35:25] <furrywolf> http://img19.photobucket.com/albums/v58/Zrexxer/Tools/bd.jpg apparantly b&d made one, but no longer does
[14:35:49] <furrywolf> I've had decent luck with Ryobi
[14:35:58] <PetefromTn_> I have had a bunch of different angle grinders
[14:36:34] <PetefromTn_> I have had believe it or not a black and decker for a LONG time and it still works great. Even a metabo I used to have which is regarded as one of the best died on me.
[14:36:37] <furrywolf> so have I... I have a Makita I use mostly now, for 4.5" ones.
[14:36:58] <renesis> cheap craftsman shit is usually > ryobi and horror fate tools
[14:37:22] <furrywolf> I have a b&d 7-9" from back when they were solid aluminum and you got a good workout just holding it, never mind using it...
[14:37:26] <renesis> and its usually about the same price
[14:37:34] <renesis> ha b&d
[14:37:58] <renesis> as good as ryobi but odd because you can also buy b&d food processors and crock pots
[14:37:59] <dirty_d> yea 7" grinders are tiring as hell
[14:38:08] <furrywolf> modern b&d is garbage... but they used to make some really good tools before the '80s.
[14:38:10] <PetefromTn_> http://www.acehardware.com/product/index.jsp?productId=2808177&KPID=3912905&kpid=3912905&pla=pla_3912905 I THINK this is the one I have
[14:38:38] <PetefromTn_> hate to disagree but
[14:38:57] <PetefromTn_> like I said I have had this one for several years now under almost daily abuse and it still works great.
[14:39:15] <dirty_d> looks decent http://www.ebay.com/itm/Makita-4-1-2-Paddle-Switch-AC-DC-Angle-Grinder-9557PB-RECON-/281709502273?pt=LH_DefaultDomain_0&hash=item419731df41
[14:39:19] <furrywolf> dirty_d: the one pete just pasted might be one for you
[14:39:22] <dirty_d> i always confuse makita and milwakee
[14:39:36] <PetefromTn_> I have bought several harbor freight electric tools and basically every one has failed quickly
[14:39:37] <renesis> theyre both pretty good
[14:40:04] <dirty_d> i have a die grinder taht still works, but ive only used ot for a total of 5 minutes
[14:40:25] <PetefromTn_> I have like six different pneumatic die grinders
[14:40:43] <dirty_d> i got an electric one
[14:40:44] <furrywolf> http://cdn.globalauctionplatform.com/abc4e4cd-286b-4d1d-afeb-a2ae00019eae/923ff9c7-8bc7-4027-e98b-0011d5b0b8e1/540x360.jpg I have an old b&d like those... they don't make them like they used to. :)
[14:40:46] <PetefromTn_> I also have two US made high speed pencil grinders that are really cool for small stuff
[14:41:05] <renesis> furrywolf: is that shit from like the 50s
[14:41:15] <furrywolf> if you put a wire brush on it, and it catches, it'll either rip it out of your hands or send you flying. :P
[14:41:19] <furrywolf> it doesn't stall. ever.
[14:41:25] <dirty_d> i always felt like the whole point of air tools was to sell air compressors
[14:41:41] <PetefromTn_> Love my air tools. Got tons of them.
[14:42:00] <furrywolf> I have lots of air tools too.
[14:42:09] <dirty_d> like whats the point? is an air motor smaller than an electric motor of the same power?
[14:42:43] <renesis> prob more reliable
[14:42:45] <furrywolf> http://fw.bushytails.net/airtools08.jpg there's a picture of some of them from 8 years ago, when someone asked about them. lol
[14:43:04] <PetefromTn_> I have quite a few air tools that are more than a decade old that still kick ass when I use them
[14:43:06] <renesis> air and magnetic gaps are both hella inefficient
[14:43:11] <furrywolf> dirty_d: air motors have a much higher power/weight or power/size ratio. they let you get lots of power, with the big heavy electric motor somewhere else.
[14:43:36] <PetefromTn_> in industrial applications you see an awful lot of air tools
[14:43:52] <dirty_d> yea
[14:43:55] <PetefromTn_> even in the cabinet shops I worked in almost everything that was not a saw was pneumatic
[14:44:09] <furrywolf> http://fw.bushytails.net/airtools05.jpg I like swivel hoses on mine.
[14:44:12] <dirty_d> the electric motor is power tools can be a hell of a lot more powerful, they just arent
[14:44:21] <dirty_d> like RC motors are rediculously powerful for the size
[14:44:26] <renesis> in the cabinet shop i was at, only electric shit was the cnc router and the little hand routers for doing edges on the laminate
[14:44:34] <PetefromTn_> sanders, nailers, grinders, impacts, sprayers, etc. etc.
[14:44:43] <renesis> oh and the bigass table saw
[14:44:46] <furrywolf> I wish I still had a shop. :(
[14:44:54] <dirty_d> but youre kinda stuck with shitty brushed motors for 120V tools
[14:44:59] <furrywolf> RC motors are ridiculously good at burning out, too.
[14:45:19] <dirty_d> not if theyre cooled, they have no brushes
[14:45:25] <dirty_d> the only moving parts are the bearings
[14:45:44] <renesis> i want a big empty warehouse without columns for measuring speakers
[14:45:48] <furrywolf> good point. I've only used brushed ones.
[14:45:58] <renesis> giant shop with nothing in it!
[14:46:00] <dirty_d> i dont think they even make brushed rc motors anymore
[14:46:14] <renesis> im sure they do for cheap shit
[14:46:24] <dirty_d> the stuff is so cheap too, you cna get an 8kW motor for like $150
[14:46:24] <renesis> nothing cheaper than brushed dc
[14:46:31] <furrywolf> renesis: want a pair of Wharfedale 12" woofers? I picked them up at a yard sale, but don't have any wharfedales to put them in. I'm tempted to stick them in my ESS AMT-1s, but I'd have to cut the 10" hole to 12"...
[14:46:43] <dirty_d> renesis, i think brushless are cheaper now because theyre simpler
[14:46:49] <dirty_d> the compexity is moved to the controller
[14:47:10] <renesis> dirty_d: i just mean for smaller stuff
[14:47:22] <renesis> you prob right for anything above a few watts
[14:47:23] <dirty_d> like you can get a 1500W brushless motor for $30
[14:47:46] <dirty_d> and its like the size of a D battery
[14:47:50] <renesis> furrywolf: i dont think so
[14:47:53] <PetefromTn_> http://i.imgur.com/7MNde0o.jpg This is not even half of my pneumatic tools and that does not even include nailers and staplers
[14:48:07] <renesis> furrywolf: unless you still have them in a month, im not at home
[14:48:19] <furrywolf> they're from the '60s. :P
[14:48:40] <renesis> yeah but they would be interesting to measure and see assembly details
[14:48:50] <renesis> old stuff can be pretty goofy
[14:49:25] <furrywolf> yeah, I've acquired more since I took that photo... and it doesn't include my nailers and staples either. have about a dozen nailers and staplers. lol
[14:49:33] <furrywolf> that reminds me, I need to fix my paslode impulse.
[14:49:43] <dirty_d> this one looks pretty good right? http://www.amazon.com/Makita-9557PB-2-Inch-Grinder-Paddle/dp/B0009OR8XO/ref=sr_1_1?ie=UTF8&qid=1435951544&sr=8-1&keywords=angle+grinder+paddle
[14:50:18] <furrywolf> got a paslode impulse on craigslist a couple months ago... it doesn't do anything. heh.
[14:50:34] <PetefromTn_> my friend at the shop I used to work in that does all their welding swears by metabo grinders..
[14:50:48] <furrywolf> I've heard metabo is good too, but very expensive.
[14:51:00] <furrywolf> renesis: I'd describe their construction as goofy, yes.
[14:51:38] <renesis> do they have open spiders?
[14:52:22] <furrywolf> no. but they do have a weird-ass square magnet mount.
[14:52:43] <renesis> the magnet is square or the frame?
[14:53:04] <furrywolf> http://www.ebay.com/itm/Wharfedale-Woofer-W60-12-4-65-W60-4-ohm-Tube-Amp-Speaker-England-2-avilable-/221387509547
[14:53:05] <renesis> either is goofy
[14:53:48] <renesis> is that aluminum or steel?
[14:53:54] <renesis> thats kind of cool
[14:53:56] <furrywolf> they're good strong magnets... I think I could stick the speakers to the bottom of a steel plate and they'd stay there. lol
[14:53:56] <furrywolf> alu
[14:54:10] <PetefromTn_> just redid my sacrificial vise jaw program for my kurt vise to have reversible jaws. Gonna power up the VMC and try to cut one set. Hopefully it works and I will be able to use existing ones I have here on the second side..
[14:54:41] <renesis> crazy how little has changed with the basic design
[14:55:09] <renesis> is almost all gap geometry, assembly and material details
[14:55:21] <dirty_d> is makita better than dewalt?
[14:55:26] <furrywolf> a speaker is a speaker. :)
[14:55:35] <renesis> no way
[14:55:36] <furrywolf> dirty_d: now that dewalt is b&d, yes.
[14:56:08] <renesis> improvements in speakers are huge, easily measurable
[14:56:11] <dirty_d> so the older dewalt tools are better?
[14:56:26] <furrywolf> I mean the construction... a moving round coil in a magnet with a cone stuck to it.
[14:56:39] <furrywolf> only speakers I have that don't follow that design are the air motion transformers on my ESSes.
[14:57:01] <dirty_d> this one looks kinda nice http://www.ebay.com/itm/DEWALT-D28402N-4-1-2-Small-Corded-Angle-Grinder-with-No-Lock-On-Paddle-Switch-/231596819990?pt=LH_DefaultDomain_0&hash=item35ec3f0616
[14:57:37] <renesis> furrywolf: planar magnetics are diff
[14:57:59] <PetefromTn_> to be honest if you are looking for an angle grinder or any electric power tool a great place to look is a local pawn shop. I have gotten some damn good deals on used electric power tools for a fraction of the new prices
[14:58:38] <renesis> and ribbon tweeter stuff, but yeah 99% of transducers are woofers (with spiders) or tweeters (without spiders)
[14:58:55] <furrywolf> http://www.ebay.com/itm/Pair-of-Heil-ESS-AMT-1A-Air-Motion-Transformer-Speakers-/271902161687 I have a pair of those I need to fix. that pair has random woofers... mine has stock woofers with no foam left.
[14:59:15] <furrywolf> PetefromTn_: the local pawn shop here charges 90% of retail, and is generally unfriendly and unhelpful.
[14:59:15] <renesis> magnet geometry might be diff because neo, but its all voice coil attached to diaphragm in a gap
[14:59:30] <furrywolf> renesis: look at the tweeters on the pair I just pasted. :)
[14:59:37] <PetefromTn_> surely there is more than one pawn shop
[14:59:41] <renesis> yeah i am
[14:59:53] <renesis> theyre ribbon or what?
[14:59:54] <PetefromTn_> besides the one I go to is the same thing but they usually come down a LOT off their asking price
[15:00:10] <renesis> they prob measure bad =\ gut feeling
[15:00:36] <dirty_d> hmm, i think there are some pawn shops around here i can check out
[15:00:46] <furrywolf> http://www.ebay.com/itm/Pair-ESS-Heil-Air-Motion-Transformer-AMT-Tweeter-/391074505592
[15:00:51] <renesis> transducers are so much better now, and you can tweak freq response with DSP with awesome results when distortion is low enough
[15:00:56] <furrywolf> they use some pleated mylar accordian-fold thing
[15:01:19] <renesis> yeah its a ribbon tweeter
[15:01:19] <PetefromTn_> don't be afraid to low ball em hehe
[15:01:31] <furrywolf> I don't remember all their literature, but they claim it stays stationary, doesn't move front-to-back.
[15:01:50] <furrywolf> instead the accordian folds roll side to side, making the gaps bigger on one side and smaller on the other side, squishing air out
[15:01:54] <renesis> prob not noticably
[15:02:12] <PetefromTn_> I just bought a milwaukee metal housing sawsall for like $40.00 and it looks and works excellent.
[15:02:20] <renesis> oh
[15:02:28] <renesis> i ithink ADAM has tweeters like that
[15:02:46] <renesis> theyre usually very low resonance
[15:03:01] <furrywolf> that is, if it looks like ___|"""|___|"""|___ etc at rest, it squishes to __|""""|__|""""|__ etc...
[15:03:26] <furrywolf> at least, that's what I remember them claiming. :)
[15:03:42] <renesis> http://www.adam-audio.com/en/technology/x-art
[15:04:42] <furrywolf> yes, and that even starts out with "a new approach to the Air Motion Transformer concept originally developed by Dr. Oskar Heil". the ones I have are original Heil AMTs...
[15:05:35] <renesis> adams sound good
[15:05:48] <furrywolf> so to heil AMTs. :)
[15:05:50] <furrywolf> so do
[15:06:06] <furrywolf> they're ungodly expensive, and very heavy. heh.
[15:06:24] <renesis> this pair is $600, thats not so bad
[15:06:45] <furrywolf> a relative has some speakers with four AMTs each... but one has a burnt out diaphragm. $100 for a new diaphragm.
[15:07:27] <renesis> not a fabric dome, but not crazy expensive either
[15:08:29] <furrywolf> PetefromTn_: heh, I got a milwaukee super sawzall for $20 last saturday at a yard sale. it seems to work perfectly, but I think once I heard the motor spin faster while the blade slowed down... hoping I didn't.
[15:08:36] <zeeshan-laptop> hi
[15:08:43] <furrywolf> or maybe it was two saturdays ago. I think last saturday I was useless.
[15:08:55] <zeeshan-laptop> you were useless yesterday!
[15:08:57] <zeeshan-laptop> you said!
[15:09:20] * furrywolf has been useless for a week and a half now. :(
[15:09:35] <zeeshan-laptop> dude
[15:09:38] <zeeshan-laptop> today is a GOOD day
[15:09:45] <zeeshan-laptop> i got back results from my experimens
[15:09:50] <zeeshan-laptop> to check repeatability of strain
[15:09:55] <zeeshan-laptop> looks pretty frigging good so far!
[15:10:14] <furrywolf> do I get my masters yet? :P
[15:10:24] <zeeshan-laptop> haha im gonna have a section on my thesis
[15:10:28] <zeeshan-laptop> in acknowledgements
[15:10:59] <zeeshan-laptop> definitely getting acknolwedged for control help
[15:11:05] <zeeshan-laptop> unfortunately all that indent work was garbage
[15:11:08] <zeeshan-laptop> and got thrown out :{
[15:11:11] <zeeshan-laptop> and abandoned
[15:11:47] <furrywolf> heh
[15:12:02] <zeeshan-laptop> welcome to research
[15:12:09] <zeeshan-laptop> 80% work is dumped in garbage
[15:13:02] <furrywolf> renesis: the x-art looks like a scaled-down, cheaper version of the AMT.
[15:13:27] <furrywolf> the AMT is much larger, with more surface area, more magnet, more power handling, and a wider frequency range.
[15:13:37] <renesis> smaller is prob much better for higher freq reproduction, 10khz is around 1" wavelength
[15:14:05] <renesis> so the bigger one prob comb filters like a mofo above few khz, is my guess
[15:14:14] <furrywolf> I think the AMT claims 800hz-20khz...
[15:14:32] <renesis> lots of companies claim lots of things
[15:14:44] <renesis> and 1/3 octave smoothed, its maybe even true
[15:14:46] <furrywolf> whoops, they say 500hz-20khz
[15:15:05] <renesis> anyway thats super low, but it makes sense crossing with a bigger woofer
[15:15:16] <furrywolf> I know my ESS AMT1s only have a 10" woofer and the AMT... they claim you don't need a midrange.
[15:15:29] <renesis> and comb filtering in the super high frequencies doesnt always sound horrible
[15:15:43] <furrywolf> 40W RMS power handling to go with the frequency range it covers
[15:15:47] <renesis> its happening anyway because of stereo interaction and room reflections
[15:15:59] <furrywolf> and they weigh 14lbs. :P
[15:16:11] <renesis> my guess is the ADAMs measure very, very well, theyre about as credible as genelec
[15:16:21] <furrywolf> my ESS AMT1s are VERY topheavy, and fall over... 14lbs for the tweeter sounds about right.
[15:16:28] <renesis> furrywolf: im sure they sound great in the mids
[15:16:49] <renesis> but i doubt highs are super accurate, but doesnt mean it sounds bad
[15:17:25] <renesis> most people dont like reference low distortion sound at first
[15:17:35] <renesis> 'this speaker makes my music sound bad'
[15:18:00] <furrywolf> lol
[15:18:05] <renesis> because theyre not used to the voicing, and they not used to hearing that many details in the mix
[15:18:30] <furrywolf> or they're not used to realizing just how poorly the band did performing or producing the music, because they couldn't hear half of it. :P
[15:18:38] <renesis> right
[15:18:55] <renesis> most people get used to it in a few songs, a lot of people realize theyre hearing more
[15:19:20] <furrywolf> my van's stock ford speakers are sometimes missing entire instruments compared to my house speakers...
[15:19:32] <renesis> my guess is over time, people hear their favorite music on enough different systems that they hear all the components, just not at once
[15:19:51] <renesis> because they always seem to response like they *know* thats how the song really sounds
[15:19:53] <furrywolf> I've decided stock ford 6x8 speakers simply suck...
[15:19:56] <renesis> *respond
[15:20:19] <renesis> they may or may not, but it wouldnt matter much as cars are very hostile acoustic environments
[15:20:21] <furrywolf> my best car stereo is uselss now. :(
[15:20:28] <furrywolf> I'll probably rip it out and put it in my other subaru
[15:20:30] <renesis> so many reflection, so much loose trim
[15:20:41] <renesis> so a camb filtering and rub+buzz nightmare
[15:20:49] <furrywolf> no point in having a good stereo in a parts car...
[15:20:59] <renesis> harmonic distortion is prob not even significant in comparison
[15:21:16] <renesis> do you ever buy from parts express?
[15:21:32] <furrywolf> no
[15:21:50] <renesis> it all comes from the same factories, and their house brand, dayton, is usually very affordable, usually measures decent
[15:21:59] <furrywolf> I buy all my stuff from yard sales.
[15:22:05] <renesis> you can get a lot of closeout and overstock type stuff too
[15:22:18] <renesis> i know, all you stuff is used up =(
[15:22:50] <furrywolf> last yard sale car audio stuff I got was a set of MB Quart QM components... 6.5" woofers, 1" tweeters, crossovers.
[15:22:52] <renesis> transducer suspension is like a clutch, only lasts so long, changes over time
[15:23:12] <renesis> the little passive xover boxes?
[15:23:25] <furrywolf> they're not so little. heavy enough they have at least a couple inductors in them.
[15:23:35] <renesis> if it has bipolar electrolytics, i wouldnt get too excited, and would be happy if they just work
[15:23:54] <renesis> if it has film caps, the shit might actually be decent
[15:24:33] <renesis> the seperate tweeters will help tho, coax is an IMD mess
[15:24:51] <furrywolf> http://www.ebay.com/itm/MB-Quart-QM-160-03-KX-6-5-Co-axial-Speakers-Pair-RSB-218-Mobile-/281736222132 like that, but with black crossovers so you can't see the insides. lol
[15:25:07] <renesis> usually takes a lot of active EQ to get FR response right, and you can EQ out suck, will still have IMD issues
[15:26:00] <renesis> really hard to tell if those are plastic or ferrite coil formers
[15:26:34] <furrywolf> I got them for my other subaru, because someone installed the door speakers such that they shut into the seats, "slightly" affecting the top end... but now that car is gone, so the project isn't happening.
[15:26:58] <renesis> i think its plastic, which is cool (air core much better than ferrite) but the caps a bipolar electrolytic
[15:27:17] <renesis> yeah how is stuff going with your accident?
[15:27:35] <furrywolf> insurance company is waiting for the police report from the highway patrol to get there
[15:27:50] <renesis> sounds normal
[15:27:58] <renesis> hows your neck?
[15:28:17] <furrywolf> I'm mostly useless, but I'm starting to be able to get basic things done again finally.
[15:28:42] <renesis> been to dr besides the initial urgent care thing?
[15:29:01] <furrywolf> no
[15:29:37] <renesis> well, dont try to get better too quick i guess
[15:29:55] * furrywolf hates being useless
[15:30:08] * zeeshan-laptop slaps furrywolf
[15:30:08] <renesis> yeah but you fuck yourself up and youll be useless a lot longer
[15:30:29] <renesis> prob best to keep moving around without doing anything hardcore
[15:31:46] <renesis> not doing anything is bad
[15:32:35] <zeeshan-laptop> renesis are you a chiropractor
[15:33:13] <renesis> this is pretty common sense stuff, also a lot of chiropractors are not great for your health
[15:33:26] <zeeshan-laptop> i guess that answers my q
[15:33:37] <renesis> most likely i am telling furrywolf stuff she already knows but doesnt want to hear =)
[15:33:54] <zeeshan-laptop> furrywolf is a he
[15:33:57] <PetefromTn_> she?
[15:33:58] <zeeshan-laptop> randy is a guys name :P
[15:34:08] <zeeshan-laptop> hi pete!
[15:34:17] <PetefromTn_> HI ZEESH
[15:34:20] <zeeshan-laptop> making more parts today?
[15:34:26] <renesis> he, she, theres strapons involved im not too concerned
[15:34:26] <PetefromTn_> you know it
[15:34:32] <zeeshan-laptop> sweet dude
[15:34:36] <zeeshan-laptop> im still impressed at that 3/4 cut
[15:34:39] <zeeshan-laptop> that shit is cool dude
[15:34:40] <PetefromTn_> got my power supply
[15:34:55] <PetefromTn_> dunno what is so impressive about it LOL
[15:35:01] <zeeshan-laptop> cause i cant do it
[15:35:02] <PetefromTn_> pretty tame really I think
[15:35:04] <zeeshan-laptop> without blowing up an end mill
[15:35:05] <zeeshan-laptop> lol
[15:35:11] <zeeshan-laptop> i wanna do it!!
[15:35:16] <zeeshan-laptop> me needs flood coolant
[15:35:16] <XXCoder> renesis: just avoid "magic hands" people and she'll be fine
[15:35:18] <PetefromTn_> you mean in stainless?
[15:35:28] <XXCoder> there is ones that belive aligning back cures everything
[15:35:55] <zeeshan-laptop> no in al
[15:36:01] <PetefromTn_> oh
[15:36:05] <zeeshan-laptop> like to give you an idea
[15:36:08] * furrywolf is a wolfy!
[15:36:09] <renesis> right but most of the people i know who use choropractors will admit that not every session actually helps
[15:36:17] <zeeshan-laptop> i was telling yesterday i can run 6 flute 1.5 cutter in aluminum no problem
[15:36:21] <zeeshan-laptop> cause the flute space is a lot
[15:36:24] <PetefromTn_> maybe try one of those maritool 3 fluters I like
[15:36:27] <zeeshan-laptop> but smaller 4 fluuters
[15:36:27] <zeeshan-laptop> i cant
[15:36:31] <zeeshan-laptop> i tied 3 flute too , a rougher
[15:36:32] <zeeshan-laptop> i snapped it
[15:36:43] <zeeshan-laptop> only thing that is happy with air blast is 2 flute
[15:36:50] <PetefromTn_> I use the high helix 3 flute aluminum specific in ally
[15:36:54] <XXCoder> zeeshan-laptop: easier to keep cool I guess
[15:37:12] <zeeshan-laptop> XXCoder: my prob is chips get packed
[15:37:18] <zeeshan-laptop> if i try to do a real cutting speed like pete is
[15:37:18] <zeeshan-laptop> :D
[15:37:33] <XXCoder> zeeshan-laptop: if I recall (dont quote me) more flutes = faster rpm?
[15:37:42] <zeeshan-laptop> no
[15:37:45] <renesis> heh i spray the chips out
[15:37:51] <zeeshan-laptop> more flutes = more feed
[15:37:56] <zeeshan-laptop> just rmember 2 formulas
[15:37:56] <XXCoder> ok
[15:37:59] <dirty_d> what are those white grinding wheels called for an angle grinder, we called them polishing wheels in shop in high school, but searching for that only shows the cloth type, these were solid
[15:38:03] <PetefromTn_> you can setup an air blast to clear chips too most likely
[15:38:07] <zeeshan-laptop> rpm = 4*cuttingspeed/diameter
[15:38:13] <renesis> chipload is less
[15:38:16] <PetefromTn_> I use flap wheels
[15:38:29] <zeeshan-laptop> feed = #ofteeth * rpm * chipload(also called feed per tooth)
[15:38:43] <XXCoder> oh yea thanks
[15:38:50] <zeeshan-laptop> PetefromTn_: itried 50psi
[15:39:01] <zeeshan-laptop> but the problem is aluminum causes a bue
[15:39:10] <dirty_d> its almost like they were cloth on the inside impregnated with epoxy
[15:39:15] <zeeshan-laptop> asap that happens, and youre going too fast, its like 5 seconds to failure
[15:39:16] <PetefromTn_> I would be surprised if I could not run the same feeds and speeds with a properly directed air blast
[15:39:24] <zeeshan-laptop> try it!
[15:39:29] <zeeshan-laptop> snap some end mills
[15:39:32] <dirty_d> they worked really damn good though
[15:39:32] <zeeshan-laptop> and let me know what works :)
[15:39:33] <zeeshan-laptop> hehehehe
[15:40:15] <PetefromTn_> dirty_d Flap wheels work great in angle grinders, cut fast but also are controllable and you can blend easily with them
[15:41:11] <renesis> zeeshan-laptop: youre not trying coolant/lube?
[15:41:43] <dirty_d> hmm, these didnt wear out though, they just got smaller like a regular grinding wheel
[15:43:10] <PetefromTn_> the flap wheels sort of just glaze over when they are done at least mine seem to. They are reasonably cheap and cut fast and smooth. Not sure what kind of wheel you are talking about.
[15:43:22] <dirty_d> yea i know i cant even find a picture
[15:43:32] <dirty_d> maybe they stopped making them because they kill you or something
[15:43:41] <dirty_d> i remember they smelled really good when you were grinding
[15:43:54] <renesis> haha
[15:44:51] <zeeshan-laptop> PetefromTn_: what kind of coolant do you run
[15:45:09] <PetefromTn_> trimsol bluish stuff
[15:45:40] <PetefromTn_> works good so far
[15:45:46] <PetefromTn_> its a solubile oil
[15:45:51] <zeeshan-laptop> ah emulsion
[15:45:52] <zeeshan-laptop> nice
[15:46:08] <zeeshan-laptop> does it stink
[15:46:11] <PetefromTn_> all I have to do is keep adding water due to evaporation
[15:46:19] <PetefromTn_> define stink...
[15:46:37] <zeeshan-laptop> like burning tapping oil
[15:46:46] <zeeshan-laptop> that tangy smell
[15:46:50] <zeeshan-laptop> sometimes sweet
[15:46:54] <PetefromTn_> no it honestly does not smell at all really.
[15:47:05] <PetefromTn_> just a sort of soapy smell I would say
[15:47:10] <zeeshan-laptop> thats not bad!
[15:47:13] <zeeshan-laptop> i dont mind soapy
[15:47:26] <PetefromTn_> so far has never gone bad either
[15:47:35] <zeeshan-laptop> how long is never
[15:47:45] <PetefromTn_> I do need to add some more of the mix to it it is getting greener
[15:48:01] <zeeshan-laptop> at my old job
[15:48:02] <PetefromTn_> as long as I have had the machine running it is the same stuff I put in originally
[15:48:10] <zeeshan-laptop> they used a similar tool like you use for cars coolant systems
[15:48:10] <PetefromTn_> I just maintain it
[15:48:13] <dirty_d> hmm this might be what im talking about http://www.bestmaterials.com/detail.aspx?ID=19889
[15:48:18] <zeeshan-laptop> to check the mix here and there cause it evaps like you said
[15:48:27] <zeeshan-laptop> wow nice PetefromTn_
[15:48:34] <PetefromTn_> as it evaporates it gets kinda thick lookig
[15:48:39] <PetefromTn_> so I just add water
[15:48:45] <zeeshan-laptop> tap?
[15:48:49] <PetefromTn_> until it flows the same as it did originally
[15:49:01] <PetefromTn_> yeah I don't deionize
[15:49:01] <renesis> whats ratio like?
[15:49:25] <PetefromTn_> I would have to check I don't recall
[15:49:36] <renesis> kind of blown away by how far the rustlick i have goes, dont think i will ever use up the whole gallon for my micromill
[15:49:54] <PetefromTn_> most shops I worked in just use a garden hose and a venturi setup to mix it right from a barrel
[15:49:57] <renesis> its like 10:1 to 30:1 or something
[15:50:26] <PetefromTn_> well I have bought a 5 gallon bucket of the stuff and still have about half left here
[15:51:17] <PetefromTn_> and the machine has dual troughs with a large diameter rubber hose across the front connecting the two troughs
[15:51:27] <renesis> and yeah the rustlick doesnt smell so much, kind of like tapping fluid i guess, not nearly as strong
[15:51:29] <PetefromTn_> don't remember how many gallons it took to fill it
[15:53:21] <renesis> i spray bottle 4 flutes with it and dont have issues with aluminum and acrylic fusing, and drips down into pockets and slots
[15:54:17] <PetefromTn_> zeeshan is there any reason you don't setup a flood system on your mill?
[15:55:12] <renesis> in pockets ill get lazy and just fill it up and let it recut chips, even then wear and fusing doesnt seem like an issue
[15:56:14] <renesis> ive had endmills cutting in aluminum-rustlick paint and not had issues with tips chipping and edges wearing, <3 water soluble lube
[15:57:15] <renesis> i thought about flood setup but i think its maybe too messy for indoors
[15:58:24] <dirty_d> ahh, here it is http://www.ebay.com/itm/4-1-2-x-7-8-Cotton-Fiber-Wheel-for-Finishing-and-Blending-/121344141740?pt=LH_DefaultDomain_0&hash=item1c40aca9ac
[15:58:35] <dirty_d> aluminum/stainless blending wheel
[15:58:50] <renesis> looks like a denim wheel
[15:59:14] <renesis> oh nice its doped with aluminum oxide
[15:59:24] <dirty_d> we used them to clean welding test plates
[16:00:10] <dirty_d> think these will explode and kill me? http://www.ebay.com/itm/FREE-SHIP-LOT-OF-20-4-1-2-GRINDING-WHEEL-DISC-NO-INTERNATIONAL-SALES-/141517165916?pt=LH_DefaultDomain_0&hash=item20f314955c
[16:00:37] <renesis> just dont stand in the cutting plane!
[16:00:44] <dirty_d> POWER MIKE, that sounds like the most chinese thing ever made
[16:00:48] <renesis> that way they can explode and not kill you
[16:00:49] <renesis> maybe
[16:01:19] <renesis> punch out brand grinding consumables
[16:05:47] * furrywolf tosses the eu3000is piston in the ultrasonic cleaner to see what happens
[16:06:12] * renesis predicts a noise will happen
[16:09:26] <furrywolf> but will you hear the noise? :P
[16:10:33] <renesis> i think so because bouncing will be sub fundamental
[16:10:46] <furrywolf> lol
[16:11:13] <furrywolf> I need to get a bigger ultrasonic cleaner... it's one of my favorite tools.
[16:11:24] <furrywolf> I can toss in dirty grimey crap, wait a few hours, and pull out a part that looks like it just came from the factory.
[16:11:40] <renesis> do you know what the big vibrating vats of abrasive are called?
[16:11:49] <dirty_d> hmm, these seem scary thin http://www.ebay.com/itm/25-Pack-4-1-2-x-040-x7-8-Cut-off-Wheel-Metal-Stainless-Steel-Cutting-Discs-/121554469693?pt=LH_DefaultDomain_0&hash=item1c4d36033d
[16:12:10] <PetefromTn_> you mean a vibratory finisher?
[16:12:13] <renesis> its not ultrasonic, you can see the thing vibrating and it swirls small parts around in abrasive slush
[16:12:45] <renesis> petefromtn_: probably, stuff looked sandblasted and it was kind of trippy to watch
[16:12:51] <XXCoder> vibratory finisher :P
[16:13:00] <renesis> sounds kinky
[16:13:17] <furrywolf> yeah, I don't have one of those. I have an ultrasonic cleaner... you fill it with water and a bit of soap, and it uses ultrasonic sound waves to blast crap off.
[16:13:39] <renesis> right ive used cheap ones
[16:14:06] <furrywolf> I have a good-quality one, but it's small.
[16:14:17] <renesis> they were work or school things tho and they didnt break so i havent gotten to take one apart, dunno what the transducers are like =(
[16:14:21] <furrywolf> it's a commercial-duty jewlry cleaner.
[16:14:25] <XXCoder> its suprising hard to find honest reviews on ultrasonic clkeaner :(
[16:14:36] <furrywolf> ... why would there be a dishonest review?
[16:14:41] <XXCoder> its always omg it rocks and omg it sucks
[16:15:03] <renesis> for the same product? heh
[16:15:08] <XXCoder> furrywolf: kidding? because compeitions sometimes hire to give good or bad reiews
[16:15:31] <furrywolf> I didn't realize the ultrasonic cleaner market was quite that cutthroat. lol
[16:15:46] <XXCoder> renesis: what im saying is that ultrasonic reviews is pretty polarized
[16:16:04] <renesis> it might just be able expectations
[16:16:13] <XXCoder> that is possible too.
[16:16:16] <renesis> theyre cheap so all kinds of people buying them for all kinds of things
[16:16:41] <XXCoder> I wanted one to clean used stock I buy from others to sell.
[16:17:08] <furrywolf> wow. there's a circuit breaker on ebay made is lesotho. I didn't know they made anything. lol
[16:17:12] <furrywolf> s/is/in
[16:17:58] * furrywolf wonders what the quality of made-in-lesotho products is
[16:18:20] <renesis> whats lesotho
[16:18:40] <furrywolf> https://en.wikipedia.org/wiki/Lesotho
[16:18:43] <renesis> oh its a kingdom
[16:19:07] <renesis> oh man thats a crappy place to put your county
[16:19:28] <XXCoder> why?
[16:19:44] <renesis> its landlocked and surrounded by south africa
[16:19:53] <Deejay> gn8
[16:20:13] <XXCoder> ren africa is big
[16:20:22] <XXCoder> you can almost fit all other landmasses in it
[16:20:40] <renesis> i think you are wrong
[16:20:48] * furrywolf also thinks xxcoder is wrong
[16:21:00] <renesis> south america alone is prob 2/3 of it
[16:21:25] <XXCoder> actually wrong yeah http://infobeautiful2.s3.amazonaws.com/true_size_of_africa.png
[16:21:31] <renesis> india and mid east and bits of europe could fill the rest
[16:21:32] <XXCoder> but still big
[16:22:07] <XXCoder> my point is that south africa has HUGE vareity of ecosystems
[16:22:41] <renesis> i dont think being landlocked and surrounded by another country gives you much trade leverage
[16:22:53] <renesis> you are going to be someones bitch to move product
[16:23:39] <XXCoder> yeah
[16:23:39] <renesis> africa is much bigger than texas
[16:23:42] <furrywolf> wikipedia says africa is 11,668,599 mi2. siberia is 57,506,055 mi2. or, roughly, 5 times larger. thus, any claims of fitting most of the world's landmass into africa... no. :P
[16:24:01] <XXCoder> renesis: no way! texas is bigger than africa, usa, earth, texas combined!
[16:24:17] <renesis> also the US fitting doesnt take into acount canada and mexico, theyre kind of big
[16:24:36] <XXCoder> usa do not contain cananda and mexica
[16:24:40] <XXCoder> north america do :)
[16:24:51] <renesis> yeah but north america does and i think they count as land mass
[16:24:59] <XXCoder> thats what I said
[16:25:02] <furrywolf> a better scale would be that africa is so friggin' tiny that you can fit five africas inside siberia. :P
[16:25:44] <XXCoder> furrywolf: heh was teasing how texans think their state is biggest in everything
[16:29:14] <furrywolf> hrmm, there's something wrong with wikipedia's numbers.
[16:29:14] * furrywolf is too lazy to look up proper values
[16:29:18] <furrywolf> ignore above size comparrison.
[16:29:56] <XXCoder> I see some navial engineer played with ksp too much https://electronicmercenary.files.wordpress.com/2015/07/20150701_151820.jpg
[16:30:02] <SpeedEvil> Steradians are the only sensible unit
[16:30:10] <furrywolf> moral of the story: wikipedia is not a reliable source. :P
[16:30:18] <XXCoder> no current local king feet is better
[16:31:15] * furrywolf looks at the image and doesn't get it
[16:31:27] <XXCoder> fur you would if you played ksp
[16:32:07] <furrywolf> it's an amphibious vehicle, with wheels on struts added to a boat... and the name "Sealegs" being a bit of a pun...
[16:32:34] <XXCoder> wheels and struts exactly
[16:33:54] <furrywolf> ok, I'll bite. what does an amphibious boat have to do with space?
[16:34:15] <XXCoder> there is people who made boats in ksp
[16:34:21] <XXCoder> including my neice lol
[16:35:19] <XXCoder> and yes it had wheels and struts lol
[16:36:12] <XXCoder> my strangest creations was ion drive plane (one of weakest motors in game) and "snowflake" a engineless plane that went 4k m/s
[16:36:22] <XXCoder> last one exploited physics error
[16:37:00] <furrywolf> lol
[16:37:16] <furrywolf> that does sound like a bit of an error, yes.
[16:37:43] <XXCoder> yeah some wings had drag but changing direction added more thrust than drag
[16:38:01] <XXCoder> comboined with SAS means wings constantly wiggle = very fast plane
[16:38:25] <XXCoder> I had orbited it lol but its lowest point was in air so drag evenually dragged it down
[16:39:40] * furrywolf isn't a gamer
[16:39:46] <furrywolf> go build real things! :P
[16:39:52] <XXCoder> lol
[16:40:08] <furrywolf> if you want to try to exploit physics errors, see if you can make the emdrive work. :)
[16:42:05] <MrSunshine> hmm compressed air to evacuate chips/cool when routing plastic, does that work ? =)
[16:42:09] <dirty_d> any news on that?
[16:45:54] <XXCoder> dirty_d: emdrive? chinese apparently successfully tested it, then nasa did
[16:45:58] <XXCoder> still dunno
[16:48:20] <dirty_d> last i heard nasa was upping the power to see if it still "worked"
[16:52:46] <XXCoder> dirty_d: I just hope it will turn out workable
[16:52:53] <XXCoder> we REALLY need reactionless drive
[16:53:00] <os1r1s> Does anyone know if there is a 2.6 version livecd that will install to a cd rather than a dvd?
[16:53:14] <dirty_d> im like 99% sure it wont
[16:54:19] <dirty_d> it cant possibly work unless its somehow extracting energy from the vacuum
[16:54:51] <dirty_d> because at some point the spacecraft would have more kinetic energy than electical energy put into the engine
[16:55:07] <XXCoder> it need massive energy to get little thrust
[16:55:19] <XXCoder> problem is why it apparently works at all
[16:55:22] <dirty_d> thats not the problem though
[16:56:07] <dirty_d> the kinetic energy increases with velocity squared, but the increase in velocity and energy into the device is linear
[16:56:26] <dirty_d> so if you thrust long enough you have more kinetic energy than you put into it
[16:56:44] <zeeshan-laptop> MrSunshine: my expwerience is if you use 2 flute cutter
[16:56:51] <zeeshan-laptop> air blast works fine
[16:57:36] <dirty_d> i bought one of those mist coolers and some kool mist lube
[16:57:41] <dirty_d> hopefully it works ok
[16:57:48] <dirty_d> the thing was only $10
[16:57:56] <zeeshan-laptop> make sure it sprays droplets
[16:57:58] <zeeshan-laptop> not actual mist
[16:58:06] <zeeshan-laptop> dont wanna be breathing mist :P
[16:58:09] <dirty_d> it said its not harmful
[16:58:19] <zeeshan-laptop> if you smell coolant
[16:58:20] <dirty_d> i think it is mist though
[16:58:21] <zeeshan-laptop> you know it is :P
[16:58:29] <zeeshan-laptop> if you dont smell it, then its working correctly
[16:59:05] <dirty_d> the material datasheet said its not harmful besides minor irritation
[17:00:03] <XXCoder> still wrong pon physics I see
[17:00:36] <dirty_d> hmm?
[17:01:48] <dirty_d> then again ciggarettes used to be considered safe, lol
[17:01:53] <MrSunshine> maybe worth buying a 1 flute router bit for soft plastics .. tho the jobs pay will only pay for the frekkin bit :P
[17:02:00] <XXCoder> suppose you got a solar car. its getting power from sun. it will evenually go faster (has more kenetic energy) than it gets from sun
[17:02:06] <MrSunshine> starting to get quite the arsenal of bits by now =)
[17:02:31] <XXCoder> OMH impossible right?
[17:02:43] <dirty_d> thats not true
[17:02:54] <dirty_d> because you have constant power in and constant power out
[17:03:01] <dirty_d> as you go faster and faster your acceleration decreases
[17:03:03] <XXCoder> well its same for emdrive
[17:03:10] <dirty_d> so your kinetic energy is always <= the power in
[17:03:15] <XXCoder> ypu feed in power and get motion and heat. mostly heat
[17:03:19] <dirty_d> no the emdrive operates on constnat thrust
[17:03:22] <dirty_d> so constant acceleration
[17:03:41] <XXCoder> with power yes
[17:03:50] <dirty_d> same thrust on increasing velocity is increasing power without bound
[17:03:54] <XXCoder> turn off power and it just keeps moving but no additional speed
[17:05:45] <dirty_d> lets say tehy make an emdrive powered 1kg test craft that can accelerate at 1m and uses 1000W of electrical energy
[17:05:56] <dirty_d> 1m/s^2 i mean
[17:06:24] <furrywolf> just checking the piston, almost entirely clean... now that I can see it better the skirt looks pretty scuffed, but I'll probably just use it anyway.
[17:06:38] <dirty_d> after 1 day your velocity is 86400m/s
[17:06:57] <XXCoder> after feeding it 1000w for a day too
[17:07:12] <dirty_d> your kinetic energy is 0.5 * 1 * 86400^2 = 3732480000.0J
[17:07:41] <dirty_d> electical energy consumed is 1000 * (24 * 3600) = 86400000J
[17:08:27] <XXCoder> J = W/s correct?
[17:08:44] <dirty_d> you can change the mass, power, and thrust to whatever you wan, and eventually your kinetic energy will be more than the electrical energy you used
[17:09:03] <dirty_d> since it increases non-linearly, but energy in increases linearly
[17:09:33] <dirty_d> thats why its not possible unless its stealing that extra energy from the vacuum
[17:09:37] <XXCoder> comelling argument
[17:09:48] <dirty_d> which is also considered impossible
[17:09:57] <dirty_d> but hopefully its not
[17:10:01] <XXCoder> good question, maybe it looks constant because it wasnt increasing speed
[17:10:04] <dirty_d> because that would be neat
[17:10:17] <XXCoder> but once in space and increasing there may be increasing resistance
[17:10:34] <dirty_d> then einstein would be wrong
[17:10:44] <dirty_d> physics should be the same in any reference frame
[17:10:56] <dirty_d> but that would also be a good thing
[17:11:00] <dirty_d> but its probably just not true
[17:11:06] <XXCoder> would be weird if there was something broken with universe LOL
[17:11:12] <dirty_d> hopefully there is
[17:11:18] <dirty_d> the universe is an asshole
[17:12:05] <XXCoder> https://dl.dropboxusercontent.com/u/53432577/snowflake.png furrywolf my snowflake, ready to go. https://dl.dropboxusercontent.com/u/53432577/snowflake1.png flying lol
[17:12:15] <XXCoder> it is lol
[17:12:56] <dirty_d> the laws of physics pretty much guarantee that we will never really go anywhere outside our solar system
[17:13:26] <XXCoder> dont be too sure about that, even with 10% lightspeec we will evenually colonize entire galaxy in few million years
[17:13:28] <dirty_d> well some people can if you could "freeze" them, but then we wont know what actually happens
[17:13:30] <dirty_d> so thats kinda lame
[17:14:31] <dirty_d> well the thing is you could build a spaceship that could go that fast and get somewhere, but then everyone on earth you knew will be dead
[17:14:33] <furrywolf> don't they sell those on TV for chopping onions? :P
[17:14:55] <dirty_d> like i said, the universe is a very unfriendly asshole, lol
[17:15:18] <malcom2073> dirty_d: Progress for the race at the cost to the individual. Many people would be very willing to take that (look at the applicant list for the mission to mars)
[17:15:52] <dirty_d> yea for sure
[17:15:58] <furrywolf> many people would be perfectly happy never to see any more people. :P
[17:17:32] <dirty_d> the thing is no country is going to pay for anything like this if only the people on the ship learn anything
[17:18:14] <malcom2073> Of course, constant communication is key, even if there is a delay
[17:20:07] <XXCoder> it would start as somewhat delayed commucation to virtually video mails
[17:20:17] <malcom2073> Yeah
[17:20:30] <XXCoder> evenually it will be "oh look our ascentors is speaking!
[17:20:32] <dirty_d> that would only really be practical for the closest stars
[17:20:50] <dirty_d> and even then, how much is a ship going to cost that may or may not make it there in 40 years?
[17:21:03] <dirty_d> if 10% is even possible
[17:21:07] <XXCoder> billions
[17:21:17] <XXCoder> but start small
[17:21:24] <XXCoder> local solar system
[17:21:33] <dirty_d> yea for sure
[17:21:38] <XXCoder> more people and workers = easier to build bigger multi generational ships
[17:22:21] <dirty_d> I think large mobile stations are a lot more practical than settling on other planets
[17:22:34] <dirty_d> gravity is a pain in the ass
[17:22:46] <dirty_d> once youre in orbit, just stay there
[17:23:15] <XXCoder> yea and evenually evolution would cull out people who has problems in no gravity
[17:23:20] <dirty_d> not neccesarily around the earth though, you can take your time moving around once you are, mine asteroids and shit
[17:23:27] <XXCoder> yea
[17:23:33] <dirty_d> artificial gravity is easy though
[17:23:41] <dirty_d> so that wouldnt even be an issue
[17:23:56] <XXCoder> heh hope we find electric -> gravoty someday
[17:24:01] <XXCoder> like electric to magnet
[17:24:09] <dirty_d> i doubt it
[17:24:15] <dirty_d> just do it 2001 style
[17:24:29] <XXCoder> rotating frame of reference is bit annoying though
[17:24:33] <XXCoder> 'unless really big
[17:24:46] <dirty_d> yea it would have to be big
[17:24:49] <XXCoder> colious force something
[17:25:00] <dirty_d> something like that
[17:29:37] <dirty_d> if a human can deal with no gravity for a year at a time though then i think most everyone can deal with a little less gravity at their head than their feet.
[17:30:18] <XXCoder> dirty though cant grow up normally with no gravity for mammals
[17:30:45] <dirty_d> you would have gravity though
[17:30:54] <XXCoder> yeah
[17:31:02] <XXCoder> fake one anyway lol
[17:31:29] <dirty_d> well technically i think it is indistinguishable
[17:31:35] <XXCoder> I know
[17:31:56] <XXCoder> more like mostly no difference
[17:33:34] <dirty_d> it would be exactly like being a certain distance away from a point of certain mass, and when you move, it changes mass
[17:34:11] <dirty_d> or something
[17:35:26] <dirty_d> i wonder what happened to that spacex rocket
[17:35:37] <XXCoder> oxy leak? lemme look
[17:36:21] <dirty_d> they dont know yet all they have said is that there was an overpressure in the oxygen tank
[17:37:07] <XXCoder> interesting
[17:37:12] <dirty_d> it seems like the only thing that could have caused that would be the helium pressurization system overpressurizeing it
[17:37:12] <XXCoder> space is hard]
[17:37:52] <dirty_d> because if the valves that vent boiling off oxygen failed they would have seen a slow steady increase in pressure
[17:37:57] <dirty_d> and it would be obvious
[17:38:24] <dirty_d> plus the hemium tanks are inside the oxygen tanks
[17:38:51] <XXCoder> tankecption
[17:39:04] <XXCoder> why is tanks combined?
[17:39:15] <dirty_d> they probably know, they just arent certain enough to make it public yet
[17:39:39] <dirty_d> there just isnt anywhere les to put them because the rocket itself is just a tank
[17:39:49] <dirty_d> the outside walls are the tank walls
[17:39:51] <XXCoder> interesting
[17:40:10] <XXCoder> you play ksp?
[17:40:13] <dirty_d> i have
[17:41:49] <dirty_d> probably wont be seeing a rocket land on a barge anytime soon
[17:42:26] <XXCoder> dunno
[17:43:01] <dirty_d> they released another video of the failed landing, pretty cool https://www.youtube.com/watch?v=NcTOTeoaafU
[17:44:33] <PetefromTn_> jeez that did not look too good
[17:45:53] <dirty_d> so close though
[17:46:34] <PetefromTn_> seemed like it came in way too fast for it to be able to adjust any
[17:46:37] <dirty_d> i think there was a problem with that particular rocket, something about throttle valve sticktion
[17:46:58] <malcom2073> the drone ship “Just Read the Instructions”
[17:47:00] <malcom2073> I love that.
[17:47:25] <PetefromTn_> maybe needs some more reading?
[17:47:31] <malcom2073> From what I've read, the rocket *can't* throttle down, the engine just isn't capable, so they have to come in full speed at high throttle for the landing
[17:48:00] <XXCoder> wonder if it should use paracles intead
[17:48:02] <dirty_d> they renamed it http://www.trbimg.com/img-558c8959/turbine/os-spacex-resupply-launch-barge-landing-sunday-001/450/450x253
[17:48:07] <PetefromTn_> then how did it actually slow down at the pad?
[17:48:36] <dirty_d> the minumum thrust is more than the weight of the rocket when its landing
[17:48:37] <PetefromTn_> LOL of course I still love you
[17:48:47] <malcom2073> dirty_d: Yep
[17:48:48] <dirty_d> so they time it so it reaches 0 velocity at 0 altitude
[17:48:58] <XXCoder> sucide burn
[17:49:02] <dirty_d> plus adjust it as muck as they can along the way
[17:49:07] <XXCoder> did that few times its crazy
[17:49:37] <XXCoder> landed at mun by just burning all way down, reached 0 speed less than meter above ground and landed
[17:49:47] <PetefromTn_> honestly the whole idea of landing a long tall stick of dynamite vertically to me is almost hard to believe possible. I salute them for ALMOST pulling it off
[17:50:10] <XXCoder> indeed heres to them finally landing
[17:50:16] <dirty_d> theyve done it a bunch of times, just not on the barge, and other times not from space
[17:50:33] <dirty_d> the water landings looked like they would have succeded if there was a barge under it
[17:50:42] <malcom2073> They're getting damn close
[17:50:54] <dirty_d> pretty sure it would have worked if not for the throttle valve problem
[17:51:00] <PetefromTn_> shudder to think how much a MISS costs heh
[17:51:16] <dirty_d> well the good thing is its free for now
[17:51:18] <malcom2073> PetefromTn_: Probably a couple percent off Elon's bonus at the end of each year :P
[17:51:43] <PetefromTn_> I need that guy to be my bestest bud... maybe I can put together a complete shop then hehe
[17:51:59] <malcom2073> hah yeah
[17:52:02] <malcom2073> Don't we all :P
[17:52:27] <dirty_d> he has to be some kind of super villain
[17:52:37] <PetefromTn_> dunno if I mentioned it before but to me that guy is just freaking amazing and much respect for him and his balls to put his money where his mouth is...
[17:53:27] <PetefromTn_> not too many times in history has someone said they were going to do so many things others thought were impossible and he just freaking does it....
[17:53:41] <dirty_d> he seriously sticks it to the man
[17:53:48] <PetefromTn_> it takes more than just tons of money to make that happen
[17:53:50] <dirty_d> making electric cars and reusable rockets and shit
[17:54:40] <PetefromTn_> yeah personally I think he is by far one of the most amazing people on earth today. Wonder if he's hiring ;)
[17:55:23] <dirty_d> he does stuff taht isnt the most profitable in the short run, but will blow everyone else out of the water when it is
[17:55:48] <dirty_d> once the rockets are actually resuable, no one will be able to compete
[17:55:56] <dirty_d> not for a long time
[17:56:02] <PetefromTn_> what is amazing to me is if you listen to him speak honestly what he has already accomplished is NOTHING compared to some of the things he wants to do
[17:56:08] <dirty_d> yea
[17:56:16] <XXCoder> dirty_d: and reusable in GOOD way too. space shuttle you gonna basically rebuild it each launch
[17:56:25] <dirty_d> yea, exactly
[17:56:32] <PetefromTn_> visionary is just inadequate description
[17:56:50] <dirty_d> hes also got that lithium battery gigafactory and methane rocket going on too
[17:57:41] <PetefromTn_> I think there are a lot of things he is working on we have not even heard about yet that will be even more amazing. He hints at some of these things in interviews occasionally.
[17:57:43] <dirty_d> hyperloop, when will it end? lol
[17:58:11] <dirty_d> yea probably
[17:58:20] <XXCoder> I hope that will be successful
[17:58:29] <XXCoder> planes is bad for envorment
[17:58:33] <dirty_d> i dont see why not, seems very doable
[17:58:40] <XXCoder> quite ironic I make lot airplane parts now
[17:58:44] <PetefromTn_> Altho watching the ruskies launch a successful rocket to the SS today was kind of a slap in the face a bit hehe
[18:00:03] <dirty_d> he said the delay will be a few months
[18:00:45] <dirty_d> they probably know what happened, just not exactly why
[18:00:56] <dirty_d> its gotta be the helium
[18:01:42] <PetefromTn_> damn I used the wrong original drawing for my soft jaw reversible mod
[18:02:03] <PetefromTn_> the one I used was for the Chinese vise instead of the kurt. DAMN gotta redo it....
[18:05:06] <dirty_d> speaking of rockets, wtf? http://digg.com/video/homemade-thai-rocket-is-a-spinning-spectacle
[18:08:28] <XXCoder> http://www.sciencealert.com/watch-a-giant-spinning-thai-rocket-blast-off-to-ridiculous-heights
[18:08:31] <XXCoder> is it same?
[18:08:43] <dirty_d> yea
[18:09:14] <greg__> Musk only got 4.9Billion in subsidies
[18:09:52] <XXCoder> wow
[18:09:56] <XXCoder> it goes on and on and on
[18:11:37] <XXCoder> talking about odd https://i.chzbgr.com/maxW500/8524382976/h641CE961/
[18:31:33] <andypugh> I wonder if I have fixed the Ner-a-Car? It died last time out, but I don’t actually know what was wrong. The crank-case gland seems to allow leakage on the “suck” stroke into the crank, but I very much doubt that the fundamental design changed half way up the hill.
[18:32:47] <andypugh> I spent all evening chasing a lack of spark, until I realised that I had nudged the safety gap on the magneto, and so it was sparking there rather than at the plug.
[18:33:01] <dirty_d> whats the ner-a-car?
[18:33:08] <andypugh> So I will re-assemble having not actually found anything wrong.
[18:33:23] <andypugh> Ah, it’s not a CNC machine or a Linux thing.
[18:33:48] <andypugh> It’s a 1921 motorcycle (that I did use LinuxCNC to restore)
[18:33:54] <dirty_d> sweet
[18:34:09] <dirty_d> have pictures?
[18:34:31] <andypugh> I have an entire step-by-step blog :-) http://bodgesoc.blogspot.co.uk/search/label/Neracar1
[18:34:32] <Jymmm> lis it that lil black one?
[18:34:37] <Jymmm> is*
[18:35:47] <Jymmm> andypugh: Whats the lil black one of you riding in the driveway video I saw?
[18:36:06] <andypugh> Aye , it is.
[18:36:44] <Jymmm> You did a nice job on that for sure
[18:37:26] <andypugh> Super-nice photos from a friend who is a pro-photographer: http://www.beautifullytold.com/ner-a-car/
[18:39:03] <dirty_d> damn, thats cool
[18:40:01] <dirty_d> how much work did the engine need?
[18:41:55] <andypugh> The engine needed almost no work, I only needed to rewind the magneto.
[18:42:13] <andypugh> (and make an exhaust)
[18:42:33] <andypugh> Oh, and straighten a bent conrod.
[18:45:54] <dirty_d> thats surprising, id figure it would be mostly rust by now
[18:46:30] <andypugh> The engine is largely aluminium, and oily. The chassis was mainly rust.
[18:46:40] <dirty_d> ahh
[18:51:29] <XXCoder> andypugh: interesting read so far

[19:47:30] <XXCoder> andypugh: amazing recovery too bad lost position
[19:48:44] <XXCoder> greg__: dang
[20:28:56] <zeeshan|2> andypugh: hi
[20:32:13] <andypugh> Hi
[20:32:28] <zeeshan|2> i need your opinion on something
[20:32:29] <zeeshan|2> mr phd
[20:32:32] <zeeshan|2> :-)
[20:32:59] <zeeshan|2> when you're checking an experiment for repeatability
[20:32:59] <andypugh> I can opinionate on any subject. But there is no guarantee of quality.
[20:33:03] <zeeshan|2> and say you do 3 tests each
[20:33:40] <zeeshan|2> posting pic of graph..
[20:34:04] <zeeshan|2> http://i.imgur.com/xBGhWgb.png
[20:34:08] <zeeshan|2> thats the pressure response trace
[20:34:27] <zeeshan|2> http://i.imgur.com/Oc9vuQt.png
[20:34:33] <zeeshan|2> here is the major strain response
[20:34:46] <zeeshan|2> do you think its better to output data like how i currently have it
[20:34:49] <zeeshan|2> or do something like this:
[20:35:34] <malcom2073> zeeshan|2: http://i.imgur.com/YPqytg5.png
[20:35:37] <zeeshan|2> http://i.imgur.com/WIKGOZm.png
[20:35:50] <zeeshan|2> a single graph with just standard deviation shown
[20:35:53] <zeeshan|2> the problem is i only have 3 samples.
[20:35:57] <zeeshan|2> so std deviation doesnt make sense?
[20:36:24] <andypugh> I like the triple graph
[20:36:47] <andypugh> It’s not mathematically pure, but it gives a good feel for spread.
[20:36:58] <zeeshan|2> well im showing spread with the error bars
[20:37:02] <zeeshan|2> (hard to see in the last pic)
[20:37:22] <zeeshan|2> like is it perfectly valid to show the triple graph in an academic paper?
[20:37:28] <andypugh> The error bars conceal raw data, and in this case I think your raw data is more illustrative.
[20:38:12] <zeeshan|2> okay i value your opinion a lot
[20:38:14] <zeeshan|2> and that makes sense
[20:38:22] <andypugh> I am not sure if there is a problem with a triple graph. Ask your prof?
[20:38:41] <zeeshan|2> i kidna wanna have it perfect for him
[20:38:55] <zeeshan|2> cause i need to focus on other issues
[20:39:03] <andypugh> Personally I would use the triple graph, but I don’t write academic papers any more, I do Poerpoint for Managers :-(
[20:39:08] <zeeshan|2> hehehe
[20:39:57] <zeeshan|2> dude im so excited
[20:40:02] <zeeshan|2> my pressure control is working
[20:40:11] <zeeshan|2> and i am in the process of getting all the major strain and minor strain data
[20:40:26] <zeeshan|2> and it all seems to be very repeatable!
[20:40:31] <andypugh> It’s pretty data.
[20:40:57] <zeeshan|2> its illustrating almost linear increase in strain vs ramping pressure
[20:41:02] <zeeshan|2> same with deramping
[20:41:20] <zeeshan|2> but you can see creep happening during the constant psi section
[20:41:52] <andypugh> You might want to do a least-squares fit on the two ramps to quantify just how linear it is.
[20:41:54] <zeeshan|2> MacGyverX: looking sexy
[20:41:59] <zeeshan|2> malcom2073: i mean
[20:42:00] <zeeshan|2> :)
[20:45:33] <malcom2073> zeeshan|2: Seems like it'll work without flexing too badly heh
[20:49:01] <robinsz> so, how exactly do I upgrade to 2.7?
[20:49:33] <robinsz> 2.6.8 doesnt really seem to do it from an apt-get update/upgrade
[20:52:52] <andypugh> robinsz: Edit your repo data in the package mangler
[20:53:13] <robinsz> ummm
[20:53:21] <robinsz> and in English?
[20:53:52] <andypugh> Ah sorry, did I fall the wrong side of “not patronising” ?
[20:54:03] <robinsz> ;)
[20:54:24] <andypugh> Like this, but 2.7 http://wiki.linuxcnc.org/cgi-bin/wiki.pl?UpdatingTo2.6
[20:54:53] <robinsz> so there isnt a prug and pray CD/DVD?
[20:55:27] <andypugh> Or edit /etc/aptsources.list.d as here: http://buildbot.linuxcnc.org
[20:56:03] <andypugh> robinsz: It’t only a package upgrade, so a LiveCD (installer + Kernel etc) is overkill
[20:56:47] <robinsz> I was wondering about trying it on another machine, if there isnt a live cd, its no problem, I cna do a 2.6.8 and upgrade I gues
[20:57:06] <andypugh> Or build from source.
[20:57:11] <robinsz> I seem to have all the other bits working nicely now, with the exception of pause
[20:57:17] <andypugh> That’s what the cool kids do :-)
[20:57:32] <robinsz> im way too old to be kewl
[20:58:21] <robinsz> I was tempted to buy a boat this week
[20:58:25] <robinsz> but I held out
[20:58:37] <andypugh> I like to think I am too kewl to be old, but the calendar disagrees.
[20:58:59] <andypugh> What boat? Was it the one I wanted but decided against?
[20:59:07] <robinsz> was yours steel?
[20:59:32] <andypugh> No. Carbon.
[20:59:55] <robinsz> there was a bruce roberts 40' steel, needing an internal refit for almost no money
[20:59:57] <andypugh> It was to ordinary boats as an R1 is to ordinary bikes: http://www.ebay.co.uk/itm/151722237294
[21:00:19] <andypugh> 6.5m with canting keel :-)
[21:00:40] <robinsz> ah yes, saw that
[21:00:46] <robinsz> did you see this one?
[21:00:47] <robinsz> http://www.ebay.co.uk/itm/40ft-aluminium-hull-Sailing-Yacht-cruise-her-or-go-short-handed-solo-racing/131541482196?_trksid=p2047675.c100011.m1850&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D32334%26meid%3Ddcf4c27e8c3b48ed9bd1c414f0cebfce%26pid%3D100011%26rk%3D5%26rkt%3D10%26mehot%3Dpp%26sd%3D151722237294
[21:01:03] <andypugh> I also looked at a Folkboat with the marvellous phrase “don’t even consider this unless you are prepared for life with a wooden pet"
[21:01:13] <robinsz> ah god folkboat
[21:01:24] <robinsz> I saw a lot of those when sailing in the aaland
[21:01:44] <andypugh> They look lovely out of the water. It’s a pretty hull.
[21:01:50] <robinsz> they smell of tar and creosote
[21:01:55] <robinsz> so do their owners
[21:02:08] <andypugh> You make that sound like a bad thing :-)
[21:02:20] <robinsz> we were on an H boat
[21:02:27] <robinsz> 6 of us ... 8 at times
[21:02:43] <andypugh> 35k is to much. when I looked at the Mini it was £6k
[21:03:04] <robinsz> https://en.wikipedia.org/wiki/H-boat
[21:03:13] <robinsz> the steel ... was 7K
[21:03:45] <andypugh> For 9k you can have a share of 17k12
[21:04:02] <andypugh> (1958 America’s Cup boat, very pretty)
[21:04:16] <robinsz> do they make you sleep standing up?
[21:04:25] <andypugh> Sleep is for race finish
[21:04:30] <englishman> what's the latest ubuntu supported by linuxcnc? 12.04 like on that upgrade page?
[21:04:45] <robinsz> a freind has a Sparkman and Stephens classic racer
[21:04:55] <robinsz> accomodation is a bit "spartan"
[21:06:06] <andypugh> englishman: Probably. The latest LiveCDs have switched to Debian. That doesn’t mean that you can’t build LinuxCNC on newer Ubuntus, but you do tend to need an RTAI kernel, or possibly an RT_PREMPT one
[21:06:13] <robinsz> http://3.bp.blogspot.com/-WuqaS4rr5z8/TniMa37NqMI/AAAAAAAAJVg/-xWzHKwL2o0/s400/Prospect%2B2001.jpg
[21:06:17] <andypugh> The Mini was very spartan
[21:06:20] <englishman> thanks andypugh
[21:07:43] <andypugh> Had a tour of the new Clipper 70s last week. They are huge compared to the 68. They are not a lot longer, but wider and flat-topped like an aircraft carrier. Pretty cool actually.
[21:09:22] <robinsz> outside my comfort zone those
[21:09:32] <robinsz> I was out on my Wayfarer the other day :)
[21:09:54] <robinsz> Port Dinorwic to Caernafon and back
[21:10:06] <andypugh> Silly picture, but gives a sense of the uncluttered deck for running about on: http://sailinganarchy.com/wp-content/uploads/2013/08/Clipper_Delivery_BrianCarlin_2013_2108__IMG-9542_BC.jpg
[21:11:03] <robinsz> goodness
[21:11:10] <robinsz> big boat
[21:11:28] <robinsz> did you see Ben Ainslies latest effort>
[21:11:29] <robinsz> ?
[21:11:32] <andypugh> Not yet
[21:12:14] <andypugh> Last weekend some friends and myself came 371st in a yacht race
[21:12:40] <robinsz> cross channel race?
[21:13:06] <andypugh> Round the Island.
[21:13:15] <robinsz> right
[21:13:22] <robinsz> in preparation for fastnet I assume
[21:13:55] <andypugh> No, not doing Fastnet. I had the chance but demurred on the grounds of cost and time.
[21:14:29] <robinsz> time ... I had some of that once
[21:15:02] <robinsz> right, I'll download 2.6.8 and do a 2.7 upgrade
[21:15:06] <andypugh> Yes, exactly,
[21:15:36] <andypugh> I want a nice little wooden boat as a project, and a private income. Because I like boats more than I like sailing :-)
[21:15:47] <robinsz> you want my GP14?
[21:16:49] <robinsz> see, can;t give them away
[21:17:15] <andypugh> No, I need heads and the option to go somewhere. (ie, must be able to cross oceans)
[21:17:32] <andypugh> Hence the Mine Transat boat looking really nice.
[21:17:38] <andypugh> (Mini)
[21:17:49] <robinsz> might be a bit small
[21:18:02] <robinsz> I consider 40 feet the minimum really
[21:18:12] <andypugh> The Mini? The clue is in the name :-)
[21:18:17] <robinsz> yes, well
[21:18:31] <andypugh> But they are intended for ocean racing by the certifiable.
[21:18:49] <robinsz> too small in my book
[21:19:12] <robinsz> I played an a Farr 39 a while back that was OK
[21:19:23] <robinsz> and a Westerley Oceanlord was fine
[21:20:10] <robinsz> that mini ... gee
[21:21:01] <andypugh> I don’t get the impression that it was a boat you could keep in the water in a Marina
[21:21:13] <robinsz> mm ... no
[21:21:20] <zeeshan|2> malcom2073: hi
[21:21:28] <robinsz> more of a trailer jobby
[21:21:57] <andypugh> There seemed to be a bag to keep the oggin out round the tilting keel.
[21:22:13] <andypugh> You wouldn’t want sea urchins living in there.
[21:22:26] <robinsz> crunch ...
[21:22:35] <malcom2073> Hi
[21:22:41] <robinsz> ive nly ever been on one tilt keel job
[21:22:48] <andypugh> One more than me
[21:22:58] <robinsz> you could lift the table top off and see the water rushing around
[21:23:22] <andypugh> Sounds very Dinghy
[21:23:31] <zeeshan|2> can you post the deformed result
[21:23:35] <zeeshan|2> so i can see whats going on in your fea
[21:24:01] <robinsz> anyway ...
[21:24:02] <malcom2073> Ahhh I already closed out, about to head off to bed. I'll post it tomorrow and ping you
[21:24:06] <andypugh> Time to sleep, need to vist parents tomorrow, and said I would be there by lunchtime.
[21:24:07] <zeeshan|2> okay :D
[21:24:13] <zeeshan|2> guys its only 10 pm
[21:24:15] <zeeshan|2> why so early!
[21:24:18] <robinsz> same, see you
[21:24:19] <andypugh> 3am here
[21:24:22] <zeeshan|2> jeez
[21:24:24] <robinsz> 03:01
[21:24:25] <malcom2073> Married with kids man :/
[21:24:27] <malcom2073> kills the nightlife
[21:25:49] <XXCoder> boo
[22:02:06] <os1r1s> Can someone help me set the isolcpus paramter?
[22:49:20] <furrywolf> zeeshan seems to have some form of insomnia.
[22:50:11] <norias> how do you know this?
[22:51:27] <XXCoder> zee sleeps?
[22:51:45] <furrywolf> because he's always complaining when other people go to bed at already-too-late hours, saying they're too early.
[22:52:17] <XXCoder> oh its just the case of zee never sleeping so he dont understand concept of sleeping and waking up heh
[22:52:17] <norias> someone is complaining on reddit
[22:52:23] <norias> in my cities sub
[22:52:41] <norias> that the city will pickup trapped pest animals
[22:52:45] <norias> but that...
[22:52:48] <norias> they get killed!
[22:52:53] <norias> trap and kill!
[22:53:11] <norias> i don't have the heart to say i am also upset about this
[22:53:20] <norias> because i think it should be kill and trap
[22:53:26] <norias> or just kill, kill, kill
[22:53:53] * furrywolf doesn't like killing animals
[22:54:11] * XXCoder dont like unesscary killing
[22:54:47] <norias> define necessary
[22:54:57] <XXCoder> diffult.
[22:54:57] <Jymmm> Kill for food, not sport
[22:55:08] <XXCoder> yeah thats one of aspects
[22:55:16] <norias> i say it's necessary to shoot the groundhogs that eat my garden
[22:55:21] <XXCoder> what I hate worse is hunt and kill for selfie and fur
[22:55:23] <norias> and destroy my stuff
[22:55:37] <Jymmm> They were thre first
[22:56:32] <norias> they aren't there, anymore
[22:56:55] <Jymmm> Neithr are the Native Americans
[22:57:07] <XXCoder> norias: that falls into "gray area" for me
[22:57:20] <XXCoder> I think its not allright but its not big enough for me to worry
[22:57:33] <norias> i don't see the big deal
[22:58:50] * furrywolf doesn't see the big deal with shooting norias, but figures norias might mind.
[22:59:08] <Jymmm> Now, you could just lay down chew proof mesh and not have to kill anything
[22:59:42] <norias> trap them in their holes?
[22:59:46] <norias> that's harsh
[23:00:04] <Jymmm> unger your garden for next season
[23:00:27] <norias> they eat it from the top side
[23:00:34] <norias> walk up to the plants
[23:00:48] <Jymmm> so put a fence around it
[23:00:54] <norias> furrywolf: it's been tried. eh.
[23:01:34] <norias> fascinating idea, Jymm
[23:01:55] <norias> .22 rounds are cheap, though
[23:02:10] <Jymmm> you just rather kill it seems.
[23:02:24] <Jymmm> give them a gun make if a fair fight =)
[23:02:52] <norias> still wouldn't be fair
[23:02:55] <norias> no thumbs and all
[23:03:21] <norias> eh, my wife felt the same way till they got in the garden
[23:03:24] <Jymmm> So they can have proxy shooters. I think furrywolf would volunteer for that
[23:03:28] <norias> she's odd
[23:03:32] <norias> (my wife)
[23:03:51] <norias> she hunts, but i'm not allowed to hunt the animals in our yard
[23:04:22] <norias> i'd take that deal, if furrywolf wants to be guardian of the groundhogs
[23:05:04] * Jymmm hands furrywolf a phalanx
[23:15:03] <XXCoder> http://www.cinema52.com/2013/wp-content/uploads/2013/09/Shag2.jpg
[23:15:09] <XXCoder> cant find video of that dannit lol
[23:15:53] <furrywolf> what takes breakers that have what look like giant banana posts on the back?
[23:16:19] <furrywolf> http://i.ebayimg.com/00/s/MTM4NlgxNjAw/z/UkcAAOSwYGFUuGod/$_57.JPG like those
[23:25:05] <zeeshan|2> hello friends
[23:26:22] <zeeshan|2> furrywolf: HELLO
[23:27:19] <XXCoder> yo
[23:28:43] <zeeshan|2> hi
[23:29:35] <zeeshan|2> I present you strain data and verification of pressure response: http://i.imgur.com/Wy0WHeO.png ; http://i.imgur.com/2mgmnGT.png ; http://i.imgur.com/i6gVFQv.png
[23:31:13] <zeeshan|2> this stuff is CREEPing like mad
[23:33:09] <furrywolf> strain being measured displacement?
[23:33:23] <zeeshan|2> kind of
[23:34:03] <furrywolf> also, no graphs of behavior vs temperature? :)
[23:34:04] <zeeshan|2> its defined as change of length over original length
[23:34:14] <zeeshan|2> right now im just testing the repeatability of the tests
[23:34:21] <zeeshan|2> i ran the same experiments at different ramp rates
[23:34:24] <furrywolf> right, so it's based on measuring the size. :P
[23:34:45] <zeeshan|2> you said measured displacement
[23:34:47] <zeeshan|2> its not displacement :P
[23:35:10] <furrywolf> are you actually measuring a line across it, or just measuring how far it sticks out? :P
[23:35:19] <zeeshan|2> im measuring it at the pole of the hemisphere
[23:35:57] <furrywolf> lol
[23:36:11] <zeeshan|2> one interesting thing is this material is anisotropic
[23:36:17] <zeeshan|2> its stretching more in one direction than the other
[23:36:19] <zeeshan|2> for the same load
[23:36:27] <furrywolf> major/minor being grain direction of some form?
[23:36:41] <zeeshan|2> no
[23:36:54] <zeeshan|2> those names come from the strain element
[23:36:59] <zeeshan|2> imagine a square on a flat piece
[23:37:09] <zeeshan|2> after that flat piece becomes a hemisphere
[23:37:27] <zeeshan|2> how that square stretches/compresses along its two axis is major and minor strain
[23:37:31] <zeeshan|2> major being the bigger amount of strech
[23:37:43] <jmkasunich> does anyone know if documentation for older versions is online anywhere?
[23:37:59] <furrywolf> ... yes. and I'm guessing it's due to grain direction of some form?
[23:38:00] <zeeshan|2> im just amazed at how repeatable the test is
[23:38:10] <zeeshan|2> furrywolf: its a polymer
[23:38:11] <zeeshan|2> there are no grains
[23:38:19] <furrywolf> and yet it has directionality. :P
[23:38:23] <zeeshan|2> nots not a polycrystalline material
[23:38:27] <zeeshan|2> *its
[23:38:35] <zeeshan|2> yes
[23:38:44] <zeeshan|2> im almost damn sure it's been made through a calendering process
[23:38:47] <zeeshan|2> which is very similar to rolling
[23:39:13] <zeeshan|2> one thing to note is that major and minor strain
[23:39:18] <zeeshan|2> become almost the same upon unloading
[23:39:28] <furrywolf> so... isn't it supposed to be a shape memory polymer? why does it look like it's not holding its shape?
[23:39:29] <zeeshan|2> its such a weird material
[23:39:41] <zeeshan|2> cause im not thermocycling it
[23:39:51] <furrywolf> 25C is above the threshold?
[23:39:56] <zeeshan|2> yea
[23:40:00] <zeeshan|2> around 21-28C
[23:40:01] <furrywolf> I thought you were talking 300 degrees at some point. :P
[23:40:03] <zeeshan|2> is it's glass transition
[23:40:14] <zeeshan|2> so i'd need to be around 15-10C to store it's shape
[23:40:21] <zeeshan|2> im pretty sure that will be my next test
[23:40:23] <zeeshan|2> thermocycle
[23:40:29] <zeeshan|2> actually i wanan blow some of these up first
[23:40:50] <furrywolf> in this part of the world, blowing things up is traditional tomorrow.
[23:40:59] <zeeshan|2> hahaha
[23:41:06] <zeeshan|2> dude its just exhillerating
[23:41:12] <zeeshan|2> even though you know it's gonna kaboom
[23:41:17] <zeeshan|2> you still shake
[23:41:22] <PetefromTn_> Speaking of blowing things up hehehe
[23:41:27] <furrywolf> I think there's a fetish for that.
[23:42:10] <PetefromTn_> paid a visit to our local fireworks stand this evening..mortars and roman candles, and bottle rockets Oh my!
[23:42:43] * furrywolf checks, and google finds 388,000 results for balloon popping fetish.
[23:42:57] <zeeshan|2> lol
[23:43:13] <furrywolf> PetefromTn_: all illegal here. :P
[23:43:42] <furrywolf> so apparantly you're not the only one who finds exploding polymers to be exhillerating and make you shake all over. :P
[23:44:19] <zeeshan|2> you know whats even more fun?
[23:44:21] <zeeshan|2> blowing metal up
[23:44:27] <zeeshan|2> with hydraulic pressure
[23:44:37] <PetefromTn_> yeah I used to live in Sacto and you can't buy none of this stuff legally
[23:45:29] <furrywolf> make a graph of popping pressure vs temperature. claim it's research.
[23:47:21] <furrywolf> it's all available here, just not legally. and you have to make sure you have a lookout up the road to tell everyone to scatter if any cops head that way.
[23:47:59] <PetefromTn_> Hard to hide mortars that fly up a couple hundred feet heh
[23:48:17] <furrywolf> yes, which is why you set them off somewhere that's not your house, with a lookout. :P
[23:48:53] <furrywolf> some of the amateur fireworks shows here are better than the ones the city puts on...
[23:49:04] <furrywolf> and every year the cops try busthing them
[23:49:07] <furrywolf> busting
[23:49:48] <furrywolf> http://humboldt.craigslist.org/tls/5102659936.html wow, that's an ugly color scheme.
[23:53:59] <furrywolf> I think I'll look for something more modern and a lot less kludgey-looking... but for some reason TIG is stupidly fucking expensive.
[23:54:04] <furrywolf> next cheapest TIG on craigslist is $1900...
[23:54:50] <PetefromTn_> I have an L-tec Transformer machine. It's a 350 amp beast...works great for years now
[23:56:18] <furrywolf> I'm trying to find someone who will take a honda generator as trade. :)
[23:56:27] <furrywolf> as I don't have nearly enough cash for the prices people are asking!
[23:56:52] <PetefromTn_> I bought mine from an older local fellow for $1k
[23:57:58] <furrywolf> $1k is a couple weeks' net income... not spending it on a toy.
[23:59:58] <furrywolf> or, it's a couple months of not eating. heh.
