01:53 AM rue_bed: hi
01:29 PM Tom_L: rue_mohr
04:28 PM Tom_L: May 28, 2019 at 12:02 pm
04:28 PM Tom_L: Delivered
06:31 PM zhanx: blah today sucked
06:31 PM zhanx: the local IT department was terrible
06:34 PM Tom_L: ignorant?
06:35 PM zhanx: yep
06:35 PM zhanx: 4 -48 port cisco's not one wire labeled on the router or physically
06:36 PM Tom_L: all colorcoded.... grey
06:36 PM zhanx: they are not gonna like the bill
06:36 PM zhanx: all color coded black but yea
06:37 PM zhanx: it was funny Tim Hortons IT was like what do you mean there is no rack everything is in a pile on the shelf
06:37 PM zhanx: sent a photo
06:38 PM Tom_L: heh
06:38 PM zhanx: needless to say its right now for the rack and everything is labelled on the routers and banked right
06:39 PM zhanx: oh and 2 routers are removed as they were hooked to nothing but old wires after tracing out the place
06:40 PM zhanx: It amazed me the IT dept didn't have a console cable
06:42 PM zhanx: Tom_L, I watched them search for one for 20-25 minutes, then find an old serial port one and failed to find a laptop that it would work on before I pulled out my usb one
07:30 PM rue_mohr: zhanx, how do you define "captin" I was thinking about it, and I dont know the commonality
07:30 PM rue_mohr: Tom_L, delivered?
07:30 PM rue_mohr: I'll go check the box
07:31 PM rue_mohr: heh
07:31 PM zhanx: Captain or captin the drug
07:31 PM rue_mohr: ok, mailbox!
07:31 PM rue_mohr: maybe my new credit card is there...
07:32 PM rue_mohr: captain
07:32 PM rue_mohr: cause, there is a ship captain, but its also a position where your not commanding a machine...
07:32 PM zhanx: Captain is a company level commander rank in the Army, a rank of a smaller to mid size vessel
07:32 PM rue_mohr: but not driving it, cause thats the pilot...
07:33 PM zhanx: Captain is also the senior pilot
07:33 PM rue_mohr: aha
07:33 PM rue_mohr: that would start to define the duality
07:33 PM rue_mohr: "company level" aka, on the field ?
07:33 PM zhanx: Captain is the senior ranking person in most areas minus the navel
07:34 PM rue_mohr: hmm
07:34 PM rue_mohr: so, aside from seniority, there isn't much difference
07:34 PM zhanx: with very larger ships its Admiral with 5-10 captains
07:34 PM zhanx: no
07:34 PM rue_mohr: a ship with 5-10 captains?
07:34 PM zhanx: captain of the watch
07:35 PM zhanx: captain of the guard
07:35 PM rue_mohr: whats the name of the guy driving the ship tho
07:35 PM zhanx: (yes two different things)
07:35 PM rue_mohr: pilot?
07:35 PM rue_mohr: hmm
07:35 PM zhanx: Helmsman with a Navigation Captain
07:35 PM rue_mohr: hmm
07:35 PM rue_mohr: ok
07:36 PM zhanx: Got to remember on very large ships they have daughter ships
07:36 PM zhanx: So the biggest ship has the main dude in charge with underlings
07:36 PM rue_mohr: ok, that makes sense
07:40 PM Tom_L: rue_mohr, you goin sailin?
07:40 PM zhanx: that is what i was wondering
07:42 PM rue_mohr: no I was thinking about space ships again today
07:42 PM rue_mohr: peanuts!!!
07:43 PM rue_mohr: and
07:43 PM rue_mohr: their not edible ones tho
07:43 PM rue_mohr: phuaph
07:43 PM Tom_L: welcome to try
07:43 PM rue_mohr: phuaph
07:43 PM rue_mohr: phphhpphppp
07:44 PM zhanx: well musk is building one out out stainless steel
07:44 PM rue_mohr: what dis! what dis!!
07:44 PM zhanx: https://www.businessinsider.com/elon-musk-spacex-steel-test-hopper-starship-texas-2019-1
07:44 PM rue_mohr: ooo
07:45 PM rue_mohr: 4x u2! :)
07:45 PM zhanx: plus he has started on 3 startships
07:45 PM zhanx: starships
07:45 PM Tom_L: mustuv sent the wrong box....
07:45 PM rue_mohr: did anyone warn him about the metelergy of stainless?
07:45 PM rue_mohr: SWEET programmer!!!!
07:45 PM zhanx: they did then he schooled them on it
07:46 PM rue_mohr: he isn't worried about how it fatiuges?
07:46 PM zhanx: no one knew musk was conducting experiments on it at space temps
07:47 PM rue_mohr: oooo steeeeeel
07:47 PM zhanx: what i got of the talk, at those temps stainless steel is not able to tear in the same way
07:47 PM rue_mohr: so you just have to keep it hot
07:48 PM zhanx: it self arrests the fatigue tears at supercool temps
07:48 PM rue_mohr: ah, ledges incase I have to pry it!
07:48 PM rue_mohr: I think you mentioned that
07:48 PM Tom_L: they're not deep enough
07:49 PM Tom_L: kindof an afterthought
07:49 PM Tom_L: i'd grind em deper
07:49 PM zhanx: not really an afterthought if they spent 5 years testing materials for it
07:49 PM rue_mohr: I just want to try it
07:49 PM rue_mohr: I wonder if I have to preheat them
07:49 PM Tom_L: try one
07:50 PM Tom_L: i'd do a little cleanup on it first
07:50 PM rue_mohr: ok!
07:50 PM zhanx: liquid nitrogen !
07:50 PM zhanx: super cool it and drill it
07:50 PM rue_mohr: I'll just try it straight off and see if it'll cast at all
07:50 PM rue_mohr: zhanx, did you see the steel molds for casting alum?
07:50 PM Tom_L: small enough it might work
07:51 PM zhanx: yep
07:51 PM zhanx: Tom_L, showed me
07:51 PM rue_mohr: I think I should pour fast...
07:51 PM zhanx: pour fast and vacuum chamber it
07:51 PM rue_mohr: I cant do that...
07:52 PM rue_mohr: I can preheat, and pour fast
07:52 PM rue_mohr: hmm, it wont spit at me
07:52 PM rue_mohr: a ladel would be handy
07:52 PM zhanx: https://www.youtube.com/watch?v=UMNA6T-yaB4
07:55 PM rue_mohr: hmm
07:55 PM rue_mohr: youtube is sure I like locomotives
07:55 PM rue_mohr: got to think
07:56 PM rue_mohr: should I melt down most of the scrap I ahve and muffin it too
08:02 PM rue_shop1: ok
08:02 PM rue_shop1: first firing of the year...
08:02 PM rue_shop1: some things need a bit of help
08:02 PM rue_shop1: (some things need lots)
08:02 PM rue_shop1: and some things will get it!
08:03 PM Tom_L: you think it'll do ok?
08:03 PM Tom_L: i have no clue
08:04 PM Tom_L: if you do a dmesg, i'm not sure if sserial shows up there or not but you could look
08:04 PM Tom_L: wrong window
08:06 PM rue_shop1: no holes in the pot
08:06 PM rue_shop1: I have no clue either!
08:07 PM rue_shop1: I'm eager to try
08:07 PM rue_shop1: can you imagine if it works out really well?
08:07 PM rue_shop1: what kinda things you can make?
08:07 PM rue_shop1: fire, next step I need fire
08:07 PM Tom_L: what can you imagine?
08:10 PM Tom_L: if you keep the pot hot, maybe you can do several at a time
08:10 PM Tom_L: that'll keep the mold nice n hot
08:13 PM rue_mohr: yea, I'm curious about the cooling time too
08:14 PM rue_mohr: its heating a load, I need to change my pants and make a ladel
08:15 PM Tom_L: ahh, gonna attack it tonight?
08:44 PM rue_shop1: ladel is done, wating for the rest of the alum to melt
08:44 PM rue_shop1: would help if I stopped putting more in
08:45 PM Tom_L: you only need a teaspoon full :)
08:45 PM Tom_L: or a tiny bit more
08:46 PM zhanx: look at shirts
08:46 PM zhanx: wow that came out wroing
08:46 PM rue_shop1: almost at 2L
08:47 PM zhanx: ok, I am looking at shirts for my company etc, rue do you wear full sleeve or polo style
08:47 PM Tom_L: polo would look more professional imo
08:48 PM zhanx: yea talking with the wife, the helpers will wear polo shirts with their name on them and the company stuff
08:49 PM zhanx: 2 polo's each with 3 shirts a sweat shirt and a jacket some day
08:52 PM rue_shop1: erm where did my bottle of powdered babies go?
08:53 PM zhanx: check the vacuum
08:58 PM rue_shop1: eeep face shield
09:05 PM rue_shop1: aluminum doesn't pour nice, practising...
09:06 PM Tom_L: don't cook your toes
09:06 PM zhanx: dont worry rue doesn't eat meat
09:09 PM zhanx: lol i just got an email about today client cant find key to the rack, I responded back, they lost it in 08 so i pulled the lock clip and installed the stuff they stacked next to it, they need a new lock for it
09:15 PM rue_shop1: fail, trying again
09:15 PM rue_shop1: need a funnel tho
09:16 PM Tom_L: yeah i wondered about that spout
09:16 PM Tom_L: kindof a small target to hit
09:35 PM rue_shop1: wow
09:35 PM rue_shop1: yea
09:35 PM rue_shop1: and the mold causes the aluminum to cool pretty damn fast
09:36 PM rue_shop1: tried to preheat it, but the bottle was freezing up as the sun had gone down
09:36 PM rue_shop1: I got 3 tries in,
09:36 PM rue_shop1: 1) a bit of promise
09:36 PM Tom_L: well you're learning about it
09:36 PM rue_shop1: 2) dismal fail
09:36 PM rue_shop1: 3) dont know yet ;)
09:36 PM rue_shop1: but I got 23 muffins
09:36 PM rue_shop1: and a ladel
09:36 PM Tom_L: but you got something to play with
09:36 PM rue_shop1: the scrap bin is now half empty
09:37 PM rue_shop1: yea, and it might work if I can preheat it enough
09:37 PM rue_shop1: I couldn't get it glowing
09:37 PM rue_shop1: after the first pour, the steel was a perfect blue
09:38 PM Tom_L: huh
09:39 PM Tom_L: maybe you need to insulate it too
09:40 PM rue_mohr: the second try I tried to use a pipe fitting to funnel it in, it sucked out all the heat instead
09:40 PM rue_mohr: that entry taper tho? I think I got 3 perfect caastings of that
09:40 PM rue_mohr: :)
09:41 PM Tom_L: hah
09:41 PM rue_mohr: I'll take more pics as it cools n stuff
09:41 PM Tom_L: all new ground for me
09:41 PM Tom_L: you must need alot more heat on the mold
09:42 PM rue_mohr: I have a larger tank that moon gave me, I can try that next time
09:42 PM rue_mohr: I have lots more aluminum
09:43 PM rue_mohr: there is still a wheel rim, 2 engine heads, pullies, ...
09:43 PM Tom_L: you can still use what you spilled
10:05 PM rue_shop1: totally
10:05 PM rue_shop1: I just send it off to recycling and wait for them to turn it into another lawn mower that I break up and melt down to try the pour again
10:13 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/smelter/p1120470.jpg
10:13 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/smelter/p1120471.jpg
10:18 PM rue_mohr: oooo
10:18 PM rue_mohr: and the results...
10:19 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/smelter/p1120478.jpg Casting One, - pour aluminum everywhere
10:19 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/smelter/p1120479.jpg Casting two - overcool the metal with a useless funnel
10:20 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/smelter/p1120481.jpg casting 3 - preheat and pour like hell
10:20 PM rue_mohr: !!
10:20 PM rue_mohr: so! I think if I make 2 more air vents on the top, it might work!
10:20 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/smelter/p1120482.jpg
10:21 PM rue_mohr: it doesn't flow into that step, less being incomplete, its awesome!
10:23 PM rue_mohr: ??
10:24 PM Tom_L: wonder if we should fill from the other end
10:25 PM Tom_L: skinny to fat
10:25 PM rue_mohr: I think two small vents in the top will fix 'er up
10:25 PM rue_mohr: I dont think that air can get out
10:25 PM Tom_L: clamp it and drill a couple holes
10:25 PM Tom_L: unless you hardened it when heating
10:25 PM rue_mohr: I'm thinking just a dremel cutting disk in one sde
10:25 PM rue_mohr: side
10:25 PM Tom_L: yeah
10:25 PM rue_mohr: make a little slot
10:26 PM rue_mohr: just those two top shoulders
10:26 PM rue_mohr: it comes apart super easy
10:26 PM rue_mohr: I can do it while its still like 300c
10:26 PM Tom_L: good
10:26 PM Tom_L: that was the idea
10:26 PM Tom_L: the other pins were tight
10:27 PM rue_mohr: so, I'm not callin it a fail
10:27 PM rue_mohr: definitly say its better slated for larger parts
10:27 PM Tom_L: the vent seemed to do it's job
10:27 PM rue_mohr: yes, it just needs some backup
10:28 PM Tom_L: you really only need to slot one side
10:28 PM rue_mohr: oh ya know, I think on the second one the vent got plugged
10:28 PM Tom_L: half the mold
10:28 PM rue_mohr: yea
10:29 PM rue_mohr: thats a hard hole to hit
10:29 PM rue_mohr: the metal skinns as it starts to freeze up
10:29 PM Tom_L: any bigger and i'd need thicker steel
10:29 PM Tom_L: then you'd need more heat
10:29 PM rue_mohr: I suspect my smelter isn't really as hot as it should be
10:29 PM rue_mohr: hey, I have a little kiln,
10:30 PM rue_mohr: I wonder how much energy before I'm expending more than the cnc machines to make them :)
10:30 PM Tom_L: doesn't take long to make em here
10:30 PM Tom_L: i'm sure you already have
10:35 PM rue_mohr: I think were 45 mins on the first cnc
10:35 PM Tom_L: how much does it pick up the print from the machining?
10:35 PM rue_mohr: then drill
10:35 PM rue_mohr: then sand the round edges
10:35 PM Tom_L: i did a chamfer on mine instead of round
10:35 PM rue_mohr: almost nothing, I'lldo a closeup of #3
10:35 PM Tom_L: cause i don't have a radius cutter
10:36 PM Tom_L: yet
10:37 PM rue_mohr: :)
10:39 PM Tom_L: what's A12?
10:39 PM Tom_L: i thought i had a video cutting A3 but i can't find it
10:40 PM rue_mohr: http://www.ruemohr.org/
10:40 PM rue_mohr: heh :)
10:40 PM rue_mohr: 12...
10:40 PM rue_mohr: 12 is a latch for the can clamp
10:40 PM Tom_L: that's the one i made the slot holder for you
10:40 PM Tom_L: i have one cutting it but not A3
10:40 PM rue_mohr: yup!
10:41 PM Tom_L: they go pretty quick
10:41 PM Tom_L: shipping would kill that though
10:41 PM rue_mohr: right now we 3d print the triggers, but its the limit of the plastic and they have been the #1 fail item
10:42 PM Tom_L: yeah
10:43 PM Tom_L: i bet putting pins in this mold would be a fail
10:43 PM Tom_L: for the holes
10:43 PM rue_mohr: yea, some dents might be nice, but getting the shape would be awesome
10:44 PM Tom_L: you could add some pointed grub screws where they go from the outside
10:45 PM Tom_L: let the point stick into the mold
10:45 PM Tom_L: sharpen the point
10:45 PM rue_mohr: ! yes
10:46 PM Tom_L: i could probably locate the holes and send you a drill file
10:46 PM Tom_L: align the corner as 0,0
10:46 PM Tom_L: unless you just wanna guess
10:47 PM rue_mohr: its ok, I can locate it ok
10:47 PM Tom_L: put a printed part in the mold with the holes in it
10:47 PM Tom_L: and drill thru them
10:47 PM rue_mohr: first trick it getting it to pour
10:47 PM Tom_L: yeah
10:48 PM Tom_L: you think you can do multiple at once then?
10:48 PM Tom_L: if it works...
10:48 PM rue_mohr: what I realize from this, is that it would not be plausable to have ducts in a mold to distribute the metal
10:49 PM rue_mohr: but it could be plausable to make some double sided middles and stack them sideways
10:49 PM Tom_L: don't follow you
10:49 PM rue_mohr: hey you know what
10:50 PM rue_mohr: what would help would be to have a ring, like the vent around the interrior, it would buffer the casting from the heat loss
10:50 PM rue_mohr: ABBBBBBC
10:50 PM rue_mohr: where I have A and C right now
10:50 PM rue_mohr: B would have a pocket on both sides
10:50 PM Tom_L: pics
10:51 PM rue_mohr: do you know what i mean about a thermal break tho?
10:51 PM Tom_L: yeah
10:51 PM Tom_L: a hollow around the mold
10:51 PM rue_mohr: yea
10:52 PM Tom_L: you can't cut steel can you?
10:52 PM Tom_L: i'd say try to hollow it out some
10:53 PM rue_mohr: hell no
10:53 PM rue_mohr: it could probably also serve as a vent duct
10:53 PM rue_mohr: :)
10:54 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1120483.jpg
10:55 PM rue_mohr: does that make sense?
10:55 PM Tom_L: so more than one part in the mold? 4
10:55 PM Tom_L: or 3
10:56 PM rue_mohr: the middle ones might cast really well on account of having a pour on each side
10:56 PM rue_mohr: you just stack in B's
10:56 PM rue_mohr: technically, what we made are A and C
10:56 PM rue_mohr: a thought
10:57 PM rue_mohr: see if I can pour them!
10:57 PM rue_mohr: this is pretty cool
10:57 PM rue_mohr: I'd also like to try sand casting them
10:57 PM Tom_L: can you dremel a slot around it?
10:57 PM rue_mohr: dont know if I can get a good one out of my stuff tho
10:58 PM Tom_L: sand would be rougher
10:58 PM rue_mohr: probably yes, it would likley be best if its about 1/8 or 1/16 from the interrior
10:58 PM Tom_L: lots of rework
10:58 PM rue_mohr: yea, my sand castings come out kinda .... lumpy
10:58 PM rue_mohr: again, I suspect I need more heat
10:59 PM Tom_L: yeah
11:00 PM Tom_L: it would work better if you could force it in
11:01 PM Tom_L: is the radius good on those?
11:03 PM rue_mohr: its awesome
11:04 PM Tom_L: mess with it a while and see what you can come up with
11:04 PM rue_mohr: yea, this is exciting
11:04 PM Tom_L: you could always saw part of that flat hunk off it
11:05 PM Tom_L: leave the pins
11:05 PM rue_mohr: AND it motivated me to get the equip all up and going again
11:05 PM rue_mohr: there is some other casting stuff I want to play with
11:06 PM rue_mohr: I might tack in the pins
11:06 PM rue_mohr: the only reason I still have both is because it was smoulding in the grass
11:06 PM Tom_L: the pins i sent?
11:06 PM Tom_L: you may not want to, they're carbide
11:07 PM Tom_L: it might shatter
11:07 PM rue_mohr: I have some 1/8 welding rod too
11:07 PM rue_mohr: doesn't have to go right thru
11:07 PM Tom_L: i should have sent the other 2
11:07 PM rue_mohr: and, I think two C clamps is overkill
11:08 PM Tom_L: just draws heat out
11:08 PM rue_mohr: I'd almost bet, if it works, it could be welded to some pliers
11:08 PM rue_mohr: ... err parallel jaw ones...
11:08 PM rue_mohr: anyhow
11:08 PM rue_mohr: COOL
11:08 PM Tom_L: yeah some of those C type welding vise grips
11:09 PM rue_mohr: it doesn't seem to take long to cool
11:09 PM Tom_L: i knew it wouldn't
11:09 PM rue_mohr: and its better if it builds up some heat
11:09 PM rue_mohr: so if I could do a cast-a-thon it might thermally come in to a good temp
11:10 PM Tom_L: seems you definitely want to do a batch of em at once
11:10 PM rue_mohr: yea, lots of effort to melt down the metal
11:10 PM rue_mohr: but I can do 2L in a go, and I can add to it during that
11:11 PM Tom_L: maybe set the mold on a bbq cooker
11:11 PM Tom_L: small batch of charcoal
11:11 PM Tom_L: bunched around it or something
11:11 PM rue_mohr: the smelter IS running
11:12 PM Tom_L: can you use it's exhaust to heat it?
11:12 PM rue_mohr: I did throw it in the over-flame of the smelter for a while for #3, but then I got delayed and it wasn't as hot as I'd wanted, but the tank was freezing up pretty good
11:12 PM rue_mohr: yea
11:12 PM Tom_L: did the part fall out like you figured?
11:13 PM rue_mohr: yea
11:13 PM rue_mohr: no resistance
11:13 PM Tom_L: so it would be easy to do a batch
11:13 PM Tom_L: once it's organized
11:13 PM rue_mohr: I had to tap the mold a few times to get it apart, but it was all extremely co-opertive
11:13 PM rue_mohr: It might be the weekend till I try again
11:13 PM rue_mohr: have to see
11:14 PM Tom_L: np
11:14 PM Tom_L: just glad you got it all
11:15 PM rue_shop1: didn't you have a casting setup at one time?
11:15 PM Tom_L: no
11:15 PM Tom_L: i melted some lead for a well driver but that's about it
11:18 PM rue_mohr: hmm
11:24 PM Tom_L: ok, enough for one day.
11:47 PM rue_mohr: gnight
11:58 PM rue_mohr: https://www.youtube.com/channel/UCkEYj8wtK3aEW8vSGhlB43g
