12:08 AM CaptHindsight: anyone have a delta robot they want to get rid of?
12:19 AM jymmmm: CaptHindsight: let me 3d print one for you
12:30 AM CaptHindsight: jymmmm: I understand the beuty of nature but do you ever get lonely for intelligent contact?
12:30 AM CaptHindsight: beauty/beuty
12:32 AM jymmmm: CaptHindsight: It can be rough
12:33 AM CaptHindsight: farm livin is the life for me.....
12:33 AM CaptHindsight: the chores, the stores...
12:38 AM CaptHindsight: jymmmm: I'm on the edge of corn fields myself
12:39 AM CaptHindsight: but i can decide which direction to head, civilization or un-civilization
05:23 AM JT-Cave: morning
05:24 AM XXCoder: yo
06:06 AM Tom_L: morning
06:08 AM XXCoder: yo^2
07:05 AM Centurion-Dan2 is now known as Centurion_Dan
07:27 AM JT-Cave: So my van is in the shop and Rusty the truck was having issues with the back brakes dragging and by the time I figured out what was wrong I had ruined the rear disks and pads by over heating them while driving.
07:27 AM JT-Cave: So running out of vehicles and checking the radar for rain I decided to ride the GoldWing to town as it was out of gas and get new pads and rotors for Rusty. Got to O`Reilly's and got my parts... hmm the rotors did not fit in the trunk so they had to ride on the passenger seat.
07:28 AM JT-Cave: Stopped at Kroger's to fill up the Wing and noticed it getting darker and darker as I gassed up. Just as I was about to pull out it started to sprinkle so I put my wallet and pistol into the trunk and headed home. By the time I got to the edge of town it was raining pretty hard and the temperature had dropped from 91 to 72. The rain felt refreshing in a way as I rode home.
07:28 AM JT-Cave: Got to the house and dried everything off and got some dry clothes on and carried my parts to the shop. By then it had stopped raining but there is no way to get Rusty into the shop without tracking some mud in but I need to get it fixed so I had to mop the floor after getting it inside.
07:28 AM JT-Cave: Starting my repairs I notice one box has been opened so I open the other box and the two rotors are not the same and the opened one had some the spring parts from brake pads in there and were all covered up with greasy hand prints. Looking at the radar I'm not going to ride a motorcycle back to town to return the rotor, lucky for me my buddy Ricky was not busy and he gave me a ride to O`Reilly's and back.
07:28 AM JT-Cave: Hopefully today is less interesting...
08:01 AM tiwake: yesterday had the power company come out to see about getting three phase hooked into my shop
08:02 AM tiwake: he used language like 'at least $10k', but would not know exactly till a proper quote was written up, which he said he would get to next week
08:02 AM tiwake: ...shit thats expensive
08:11 AM skunkworks: sounds like our town. I jokingly asked what it would cost to get 3 phase to my garage.. 10k came out of his mouth.. The 3 phase lines are less than a block away..
08:13 AM tiwake: they have to put in transformers and string line across several poles
08:14 AM JavaBean: probably be cheaper to get a 3-phase output solar system
08:14 AM tiwake: I can't imagine it would work for heavy duty CNC machines
08:14 AM tiwake: not enough area
08:15 AM JavaBean: and you probably live in an area without decent wind
08:15 AM tiwake: there are lots of wind turbines
08:15 AM tiwake: around
08:16 AM tiwake: I'm in the middle of a town though
08:16 AM tiwake: I have a little less than 1/2 acre
08:16 AM JavaBean: then setup a solarpv and VAWT system... i think.......1/2 acre?? and you want to get 3-phase?? DUDE!
08:17 AM tiwake: ..?
08:17 AM tiwake: dude what
08:17 AM JavaBean: i think it might be more cost/benifit to grab a smallish chunk of place that already has 3 phase
08:18 AM tiwake: not really
08:19 AM tiwake: I'm only paying $74k for the house, property, storage shed, and shop
08:19 AM JavaBean: seems a bit expensive to me, but property values are a messed up topic
08:19 AM tiwake: shop is a new 25'x25' insulated steel building, built like a couple years ago
08:21 AM tiwake: it has 220 single phase going to it right now
08:22 AM tiwake: maybe I'll just get a three phase inverter... iunno
08:22 AM tiwake: I want to put a haas VF2 in it though
08:25 AM Loetmichel: tiwake: maaan, sometimes i envy foreigners... a small 100sqm house with a bathtowel sized front yard and no back yard costs around $300k here where i live in germany.
08:39 AM perry_j1987: good morning
08:45 AM skunkworks: 73 already this morning
08:49 AM perry_j1987: only 73?
08:49 AM perry_j1987: southern part of the state already 76 :P
08:50 AM skunkworks: we are up nort
09:12 AM tiwake: Loetmichel: yeah, germany has always thought more highly of its land than its worth actually is
09:13 AM tiwake: same thing about its cars... shit cars that are impossible to work on, cost how much BMW?
09:14 AM Loetmichel: my convertible: 2950 eur
09:14 AM Loetmichel: granted, its built in 2004 ;)
09:14 AM Loetmichel: just bought it in february
09:15 AM tiwake: hmm
09:15 AM tiwake: I need a hacksaw
09:15 AM Loetmichel: with 270000km on the odo (around 170k miles)
09:16 AM Loetmichel: and its only an 318ci
09:16 AM tiwake: I payed $2000 for a (manual transmission, woo) car with 67k miles
09:16 AM Loetmichel: "mower engine" you americans would probably say :-)
09:16 AM tiwake: ford escort
09:17 AM tiwake: new paintjob, new windshield
09:20 AM tiwake: https://buildblock.com/
09:28 AM gregcnc: eh I like BMW
09:33 AM tiwake: there are not many cars I like, unless they are old
09:33 AM tiwake: shit to work on
09:34 AM gregcnc: I swapped an engine in E46 recently, not a big deal
09:35 AM gregcnc: To be honest I was surprised how every fastener was easily accessible
09:36 AM tiwake: why were you surprised?
09:36 AM tiwake: because most cars are shit to work on, perhaps?
09:36 AM tiwake: heh
09:36 AM gregcnc: tha'ts my point
09:37 AM gregcnc: there was no trouble at all
09:37 AM tiwake: for that specific thing... what about transmission or rebuilding engine or fuel pump or [insert whatever thing needs replacing]
09:39 AM tiwake: sometimes they tell you to pull the engine to replace one sensor on it, depending on the car
09:39 AM gregcnc: stupid honda van is worse
09:39 AM tiwake: or in a few cases, pull the engine to change the oil
09:39 AM gregcnc: yeah oh well.
09:39 AM gregcnc: do your homework
09:40 AM tiwake: as far as I can tell, the only way to avoid all that in its entirety, is to build a kit car
09:41 AM gregcnc: most people just dump the car after the warranty is up
09:41 AM tiwake: and most people are shitlords
09:46 AM Loetmichel: tiwake: my mechanic just told me that to replace all the brake hard lines he has to pull the rear axle because they fed the lines ABOVE the diff.
09:46 AM Loetmichel: niiice
09:46 AM Loetmichel: aaand the next k€ gone... :-(
09:47 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17827&g2_imageViewsIndex=1 <- doesent look SOO bad, but apparently not that great from the underside... germany DOES use salt on the streets in winter...
09:48 AM Loetmichel: -> brake lines totally rotten, kiked the brake pedal down to the floor a few weeks ago... while driving 200kph on the autobahn :-(
09:49 AM Loetmichel: one line exploded
09:50 AM tiwake: ...and you are still alive
09:51 AM Loetmichel: yeah, i know how to drive and keep my distance
09:51 AM Loetmichel: had time enough to decelerate with the ebrake
09:51 AM gregcnc: did transmission fail too?
09:53 AM tiwake: I went off the road once going 80miles/hour
09:53 AM tiwake: that was fun
09:56 AM tiwake: the only thing that happened was some grass got wedged in between the rim of the tire and the tire, and slowly leaked out
09:56 AM tiwake: was really sick that morning... like really really sick... tried to go to work but that happened
09:57 AM tiwake: still went to work... heh
09:57 AM tiwake: left after a few hours
10:29 AM pink_vampire: Loetmichel: scary!
10:37 AM jymmmm: CaptHindsight: I think flat land / corn fields would be worse, it all looks exactly the same in all directions.
10:44 AM * JT-Cave seems to be caught up in another endless project...
10:49 AM jymmmm: JT-Cave: Making a ring?
10:50 AM JT-Cave: trying to fix the brakes on Rusty
10:51 AM CaptHindsight: jymmmm: oddly enough for this area we actually have some hills and valleys
10:51 AM jymmmm: WOW, you're the third person this week with brake issues, the other two (in here) had to use vice grips on brake lines
10:52 AM CaptHindsight: what I find odd though is that farm houses will rarely be on a hill with a great view, they tend to tuck them into wooded areas with no view
10:52 AM jymmmm: CaptHindsight: WOOHOO, I don't know why, but flatland just does not appea to me in the least. Even though I'm perfectly fine with desert.
10:53 AM CaptHindsight: I'm looking for used delta bots
10:53 AM CaptHindsight: ebay usually has some
10:59 AM jymmmm: CaptHindsight: you can't make soem easily enough?
11:03 AM CaptHindsight: jymmmm: I don't has time for everything
11:04 AM jymmmm: CaptHindsight: Just 3d print more time
11:04 AM CaptHindsight: heh, yeah you sound like reprap in 2012
11:05 AM CaptHindsight: where is my 3d printer that makes everything at home, it's 2020
11:05 AM gregcnc: would be useful to print TP and food
11:09 AM CaptHindsight: are any of the delta glue guns ok or all just crap?
11:09 AM CaptHindsight: https://www.youtube.com/watch?v=VXBr3MTs50c How to Build the Best Delta 3D Printer for the Money in 2020
11:10 AM CaptHindsight: using belts
11:10 AM jymmmm: CaptHindsight: It's more irony than 2012
11:10 AM CaptHindsight: the irony of the ironong
11:10 AM CaptHindsight: ironing
11:24 AM jymmmm: CaptHindsight: polyester, the anti ironing
11:25 AM CaptHindsight: if you haven't wrinkled polyester then you aren't trying hard enough
11:27 AM jymmmm: lol
11:28 AM CaptHindsight: is Google changing their search algorithms, they have been crap lately
11:29 AM tiwake: you are just now noticing?
11:29 AM CaptHindsight: just now mentioning
11:30 AM gregcnc: pretty soon it will be like searching amazon
11:30 AM CaptHindsight: been using the -(whatever does not apply)
11:30 AM tiwake: with people being blacklisted just as much as amazon
11:32 AM CaptHindsight: youtube without an ad blocker is like watching UHF at night in the 70's
11:32 AM CaptHindsight: commercials every 5 minutes
11:40 AM jymmmm: CaptHindsight: could just download the video
11:40 AM Loetmichel: *Pfrrrrrt* re at home... MAN i want an A/C at the company... its SUCH a relief to get into the car after a day of sweating at the desk at 36°C in the company and put the A/C on 20°C and drive home... ;)
11:41 AM jymmmm: CaptHindsight: just add 'pp' before the .com
11:42 AM jymmmm: Loetmichel: DO it, get one of those portable AC and run the exhaust hose into the Bosses office
11:43 AM Loetmichel: jymmmm: thats a bit complicated because bosses office is a story up and on the other end
11:43 AM Loetmichel: of the company
11:44 AM jymmmm: Loetmichel: Oh, well out the window then?
11:44 AM jymmmm: Loetmichel: they just use the flex duct
11:45 AM Loetmichel: yeah, but i dont see why I should buy one... thats bosses job
11:45 AM jymmmm: Loetmichel: Ok, he buys you use
11:46 AM Loetmichel: yeah, thats what i hope for...
11:47 AM jymmmm: Damnit, wheres my package, trcking shows it "out for delivery" 3 times this morning
11:59 AM veegee: I converted all my air couplers to Milton G style
11:59 AM veegee: 1/2", rated flow rate is 99 SCFM
11:59 AM veegee: you can feel the recoil in the air blow gun now at 150 PSI ahha
12:00 PM veegee: I found anything less than 1/2" air hose restricts air flow significantly unless you run at very high pressure and put the regulator at the end of the hose near the tool
12:01 PM veegee: the flexzilla hoses are so nice and lightweight. I absolutely love them and pairing them with G couplers
12:02 PM veegee: now time to find a blow gun with a 1/2" port
12:03 PM veegee: takes quite a bit of force to engage the coupler at 150 PSI though, need some upper body strength.
12:08 PM veegee: I don't know why 90 psi is the "standard" for air tools though. It's like making a 30HP motor rated for 48V. Why just why would you do that
12:11 PM roycroft: probably because 90psi is enough for most consumer/small business tools, and most consumer/prosumer compressors cannot keep up the cfm at higher pressures
12:12 PM Loetmichel: veegee: i usually use my air tools at 120psi... because the mobile compressor cant do more ;)
12:12 PM roycroft: you won't sell many tools if they require a $3000+ compressor to run
12:12 PM veegee: Yeah that makes sense
12:13 PM roycroft: now if you are using tools that really do need higher pressure ( most tools are cfm hogs, not pressure hogs ) then you need to pony up for the big compressor
12:13 PM veegee: Yeah my devilbiss 447 can do 300 psi
12:13 PM Loetmichel: roycroft: or make yone yourself
12:13 PM roycroft: also, 90psi is a lot safer than 150psi
12:14 PM roycroft: and if you're a consumer who does not know better, you're better off with a low pressure air system
12:14 PM veegee: that is true, I used to be scared of connecting pneumatic tools when I was a little kid
12:14 PM Loetmichel: btw: there is an additional reason: if the tools are made for european markets: at 120psi the safety requirements DRASTICALLY increase
12:14 PM veegee: but even now at 150 psi, the couplers are no big deal
12:14 PM roycroft: see above :)
12:14 PM Loetmichel: so most consumer devices stay below that
12:15 PM Loetmichel: the safety checks by the state i mean
12:15 PM veegee: Luckily I run a hobby only shop so don't need any auditing
12:16 PM Loetmichel: if your compressor/pressure vessel is below 120PSI and below a certain volume (cant remember, about 20 litres??) it doesent have to have as stringent a test as the bigger units have to have, also its a one time test then not one every two years.
12:16 PM Loetmichel: IIRC: those safety tests are even mandatory for customers. not only for companys
12:17 PM Loetmichel: (ok, nobody "private" really cares, but theoretically...)
12:17 PM veegee: hmmm I'll have to see that
12:17 PM veegee: I don't want to die of course, but at the same time I know those pressure vessels have a very high safety margin
12:17 PM veegee: I'll stick a camera in there and look at the rust situation
12:18 PM veegee: Also the refrigerated air dryer I bought from someone for a low price (unknown CFM rating, sticker scratched) is only drawing 50W continuous
12:18 PM veegee: I thought it was way too low to be able to do anything but it's clearly ejecting water as I use my blow gun
12:19 PM * Loetmichel has built a compressor out of an Golf GTI engine... 1.6 liter 4 cylinder, new head with valves, 60kw threephase motor on the crankshaft, some railway tracks to hold the two togehter, a 120 liter pressure vessel...
12:20 PM Loetmichel: took less than a minute to have that vessel at 24 Bar/350PSI :-)
12:21 PM veegee: 120L is pretty small
12:22 PM veegee: Mine is 120 gallon
12:22 PM veegee: and my devilbiss 447 can fill it up really quick
12:22 PM veegee: about a minute to 150 psi
12:22 PM veegee: that's with a 15 HP motor though
12:24 PM Loetmichel: yeah... we used what was "spare"
12:24 PM Loetmichel: the electromotor was a bit big
12:24 PM Loetmichel: but it worked really well for sandblasting
12:25 PM Loetmichel: and the vessel was only rated 20 bar ;)
12:25 PM veegee: probably has minimum of 2 or 3 safety factor
12:26 PM veegee: if I exceed those values though, I'm going to put them inside a blast shield cage made of 1/4" thick cold rolled steel
12:27 PM veegee: it'll be loud, but I'd be very surprised if shrapnel can penetrate that
12:32 PM veegee: I _could_ go for armour steel plate but that's quite a bit more expensive
12:39 PM veegee: Actually, I'm going to make my own desiccant air dryer using PVC pipe. I'm going to make a small blast cage and experiment with the pressure limitations of PVC
12:39 PM veegee: can't imagine PVC shrapnel penetrating 1/4" cold rolled
12:41 PM Loetmichel: veegee: you would be surprised
12:42 PM veegee: Ok I'll line the inside with armour plate then
12:42 PM Loetmichel: i managed to fire 20m glass marbles thru entire street lights with a rubber slingshot as a kid
12:42 PM veegee: street lights?
12:42 PM Loetmichel: ok, those are made of 1/8" steel here, but still
12:43 PM veegee: are you serious? no way you can penetrate 1/8" steel that easily
12:43 PM veegee: definitely not with a slingshot, regardless of the hardness of the projectile
12:43 PM Loetmichel: veegee: yes, stright upwards, thru the plastic lens, thru the natrium vapor bulb, thru the aluminium reflector and making a big dent in the steel cap
12:43 PM veegee: ok I have a 50 lb hunting bow
12:44 PM veegee: I'm going to tip my arrows with tungsten carbide
12:44 PM Loetmichel: no, it didnt penetrate the steel cap, but they always had a visible dent
12:44 PM veegee: the arrows will have much more kinetic energy than your slingshot. I'll shoot it at the 1/4" steel plate I have and see how for it gets
12:44 PM Loetmichel: i meant: dont underestimate the impact of high velocity times mass... in both meanings of the word.
12:45 PM veegee: well yeah E = mv^2
12:45 PM veegee: I mean E = 1/2 • m • v^2
12:45 PM Loetmichel: if that plastic shrapnel is fast enough it can do quite a bit of damage.
12:46 PM Loetmichel: doubt it would penetrate 1/4" steel though
12:46 PM Loetmichel: for that it had to be REALLY fast ;)
12:46 PM veegee: keep in mind, totally enclosed 1/4" thick steel plate blast cage with pressure vents
12:46 PM veegee: and if I line it with hard armour plate on the inside, it definitely won't penetrate
12:46 PM veegee: bullets won't even penetrate armour plate
12:47 PM Loetmichel: btw: that slingshot was of course illegal... 2 20 kg pull power rubber hoses from a model plane launch line instead of the original 5kg hose...
12:47 PM Loetmichel: that thing was EVIL
12:48 PM veegee: odd, not illegal here in canada
12:48 PM Loetmichel: (and good training for my "kid upper body") ;)
12:48 PM veegee: but now you sparked my curiosity. I'm going to tip my arrows with tungsten carbide and see what kind of damage it can do
12:49 PM veegee: I also have a small pump pellet gun
12:49 PM veegee: can penetrate soda cans but definitely not any kind of steel
12:50 PM veegee: It shoots lead slugs. Even if I put some kerosene or ethanol in there, not that much more power
12:51 PM veegee: I wonder what the pressure in the cylinder is after you pump it. Don't really want to disassemble to measure the dimensions
12:55 PM veegee: Hmm tungsten carbide might shatter actually. Should tip it with tool steel instead
01:26 PM Tom_L: JT-Cave, quite the morning ehh?
01:29 PM jymmmm: Tom_L: maybe his tin foil hat is croocked
01:34 PM JT-Cave: yea and it ain't over with yet...
01:43 PM tiwake: ...the garage door still has not arrived
01:43 PM tiwake: was supposed to arrive yesterday
01:43 PM JT-Cave: my hydraulic hoses have not shipped yet either
01:58 PM tiwake: were they sitting in a warehouse 5 hours away for two months?
01:58 PM tiwake: lol
01:58 PM tiwake: homedepo shitheads
02:00 PM tiwake: I called a few minutes ago and they hung up on me
02:19 PM gregcnc: heh Zoro is Grainger
02:21 PM CaptHindsight: https://en.wikipedia.org/wiki/W._W._Grainger#Subsidiaries
02:42 PM Loetmichel: *giggle* just got ordered by wife to defrost the fridges deep freezer compartment... "i cant get my ice cube maker out..." $me looks: true, the useable volume of the deep freeze compartment has shrunken to about ice cube tray size... and its frozen in. so i defrostet it (mechanically, with a wooden pan spoon)... what you find in those ice mountains... garden greens in boxes with best before
02:42 PM Loetmichel: dates of 2012 to 2018... fish in ziplock with no date, two garlic butter baguettes with "best before 2011"... it was DEFINETLY time to defrost that fridge. ;)
02:44 PM gavlee_ is now known as gavlee
03:05 PM perry_j1987: https://www.youtube.com/watch?v=FRA4yPvgEto
03:05 PM perry_j1987: been watching this
03:05 PM perry_j1987: trying to figure out how to do a power drawbar
03:08 PM CaptHindsight: rod actuator
03:08 PM CaptHindsight: rack and pinion
03:09 PM CaptHindsight: gear and lever
03:10 PM CaptHindsight: https://staging-diy.haascnc.com/reference-docs/spindle-drawbar-how-it-works-and-troubleshooting-guide
03:15 PM CaptHindsight: this one is pretty simple https://shane.engineer/blog/power-drawbar-x2-mini-mill
04:02 PM perry_j1987: looks more complicated than the one in the video
04:06 PM CaptHindsight: my kids use to ask me if something was easy or hard to do
04:06 PM CaptHindsight: it depends on who is doing it
04:15 PM jymmmm: lol
04:15 PM perry_j1987: lol
04:15 PM perry_j1987: bbiab someones buying my bandsaw for 500 bucks heh
04:15 PM perry_j1987: more money towrds the mill
04:15 PM jymmmm: Is it possible to work harden a kitchen knife by sharpening it on a steel?
04:22 PM CaptHindsight: harden a steel knife by rubbing it on steel?
04:22 PM CaptHindsight: https://www.youtube.com/watch?v=Ahf2zGVScf8
04:23 PM SpeedEvil: kitchen knives are made of a wide variety of mateirals.
04:23 PM SpeedEvil: some will work harden
04:23 PM SpeedEvil: Others the edge can be maintained somewhat by regular use of a steel to keep the blade edge non bent
04:24 PM CaptHindsight: if he rubs them enough he can weld them and harden
04:34 PM Tom_L: mmm, took the paper shredder all apart thinking the feed microswitch was bad. cleaned it all up inside and found nothing wrong. still didn't work and then i noticed the screw in fuse in the back had unscrewed
04:34 PM Tom_L: oh well. at least it's clean
04:35 PM CaptHindsight: could have been worse, could have only been unplugged
04:36 PM jymmmm: stripped plastic gears
04:36 PM Tom_L: those are all good for it's age
04:37 PM Loetmichel: jymmmm: usualy kitchen knifes (the cheap walmart kind) are made of a stainless steel thats barely hardened.
04:37 PM jymmmm: Loetmichel: one step up from walmart, but now it just doens't want to hold an edge after two years
04:38 PM jymmmm: no matter have many times I sharpen it
04:39 PM jymmmm: all the toher knives in the set are not a problem
04:39 PM jymmmm: other*
04:43 PM XXCoder: cant you re-harden it?
04:45 PM CaptHindsight: he needs one of those stay sharpened pyramids
04:46 PM CaptHindsight: blades never dull when stored inside
04:46 PM XXCoder: lol
04:52 PM Loetmichel: CaptHindsight: may i interest you in buying lady liberty from me? ;)
04:53 PM CaptHindsight: Loetmichel: have a Tower of Pizza?
04:54 PM Loetmichel: that can be arranged for the right price ;)
04:55 PM Loetmichel: jym: the sharpest kitchen knife i own is a heritage from my grandma... its about 80 years old and made of carbon steel. and yes, it rusts if you dont clean it right
04:55 PM Loetmichel: but THAT thing can take a beating AND can be sharpened to razor sharp easily.
04:56 PM Loetmichel: AND holds that sharpness for ages
04:56 PM XXCoder: man keep that blade
04:56 PM XXCoder: its getting hard to get one that good
04:56 PM CaptHindsight: I have some cheap steak knives from Sams Club that cut aluminum cans
04:56 PM XXCoder: in least without hefty price tag ob it
04:57 PM CaptHindsight: Loetmichel: do they still make great blades in Solingen?
04:57 PM Loetmichel: they do indeed
04:58 PM Loetmichel: and as i was born and raised one city over...
04:58 PM Loetmichel: (born in Wuppertal, raised in Remscheid)
04:58 PM CaptHindsight: i thought you were pretty close
04:58 PM Loetmichel: ... i tend to have good knofes in my drawers
04:58 PM Loetmichel: yes, i worked in solingen for a short time
04:59 PM CaptHindsight: Wuppertal with the upside down train

05:01 PM Loetmichel: XXCoder: if you want a good blade for working: take a good quality metal file and reforge it into one.
05:01 PM Loetmichel: THATS good blade steel
05:01 PM XXCoder: interesting
05:01 PM Loetmichel: been there done that
05:01 PM XXCoder: unfortunately no forge skills here heh
05:01 PM Loetmichel: for a "bowie knife" back in my kid days
05:01 PM Loetmichel: you can also get a large dull fine and simply grind it down
05:02 PM Loetmichel: forging is more fun though
05:09 PM jymmmm: Loetmichel: Oh I dont' expect this to be hardened, but I mean could it become "work hardened" from being sharpened?
05:10 PM Tom_L: not much
05:10 PM XXCoder: theres this very expensive computer controlled oven that can harden or de-harden stuff
05:10 PM XXCoder: it'd be nice to have but so expensive lol
05:11 PM Tom_L: some they burnish harden the edge
05:11 PM CaptHindsight: XXCoder: I can make you a really really expensive one if need be
05:11 PM XXCoder: yeah thanks for offer
05:12 PM CaptHindsight: anytime
05:12 PM Tom_L: http://www.tb-haute-coutellerie.com/en/news/article/burnishing-steel-efficiently-maintain-your-kitchen-knives
05:12 PM CaptHindsight: I can pretty much make the worlds most expensive anything
05:12 PM XXCoder: or just drop ship
05:13 PM Tom_L: but can you sell it?
05:13 PM CaptHindsight: too expensive to resell
05:13 PM CaptHindsight: precious one of a kind
05:13 PM XXCoder: "Then place the knife in a basin filled with room temperature water then immerse it in the sodium hydroxide bath for an additional 4 minutes. Repeat these steps until the desired color is obtained."
05:20 PM jymmmm: Tom_L: make one
05:21 PM Tom_L: one what?
05:22 PM XXCoder: everything since its not defined
05:23 PM Tom_L: "1"
05:25 PM jymmmm: Tom_L: expensive compuer controlled knife oven
05:25 PM Tom_L: usps has the worst tracking...
05:26 PM Tom_L: jymmmm, i did make an inexpensive toaster reflow oven
05:26 PM jymmmm: Tom_L: You should have had the gpstracker installed
05:27 PM Tom_L: wasn't an option on the checkout
05:27 PM jymmmm: Tom_L: Yep, you did. I think insulation is the key. if you don't want to use expensive ceramic wool, use perlite
05:28 PM Tom_L: since the temps were alot lower, i just used regular insul on mine
05:28 PM jymmmm: Tom_L: I molten salt (1400F) using one inch of perlite, the outside was 140F
05:30 PM Tom_L: for what purpose?
05:31 PM jymmmm: Tom_L: To test the insulation properties of perlite
05:32 PM jymmmm: Tom_L: I didn't have anything that could measure above 1000F, so the known temp of molten salt is 1400F,

05:33 PM jymmmm: the soup can I used to hold the salt was compltely destroyed, you could poke your finger thru it =)
05:34 PM Tom_L: CaptHindsight, i was just gonna use an old mower blade :)
05:36 PM jymmmm: Mmmmm, that chinese electronics when the fan turns on smell
08:50 PM snakedGT is now known as snaked
10:05 PM CaptHindsight: modified a $30 1.4mm HF spray gun to 2.0mm for primer, works great
10:06 PM CaptHindsight: like their other tools, you have to get a good one with all the holes through that should be through
10:06 PM CaptHindsight: and clean it up and reassemble properly
