12:32 AM rue_shop3: james is here! he is welding, yay
01:54 AM rue_shop3: hahahahah it shakes gooodoodododododododod
01:59 AM rue_shop4: hah, thats one indistrial sized vibrator!
01:59 AM rue_shop3: tho, it might have benifitted from not being direct drive
02:07 AM rue_: the weight of the motor makes it spin in a tornaco instead of a cylinder
02:59 AM rue_shop3: 1am
02:59 AM rue_shop3: hmm
03:28 AM rue_shop4: ok, I'll call that for a night
03:41 AM rue_: Tom_L, http://ruemohr.org/~ircjunk/projects/finisher/p1100375.jpg
03:41 AM rue_: see http://ruemohr.org/~ircjunk/projects/finisher/ for build log :)
05:16 AM Tom_L: nice one rue_
03:17 PM rue_shop3: ok, I got the volcanic rock and the pipe clamps
03:17 PM rue_shop3: scrapper has no valve springs he can just sell/etc to me
03:17 PM rue_shop3: so, think I'll go up to other town and go thru scrap metal pile
03:17 PM rue_shop3: bit hot tho
03:52 PM Tom_L: some use rubber mounts
03:53 PM Tom_L: https://www.amazon.com/Mechanical-Vibration-Damping-Mounts/b?ie=UTF8&node=16413771
04:21 PM rue_shop3: bit or rubber hose eh?
05:02 PM Tom_L: something that won't shake itself apart
05:02 PM Tom_L: think car motor mounts
05:03 PM Tom_L: generator rubber mounts
05:03 PM Tom_L: disclaimer: don't go rob the mounts off your gen
06:28 PM rue_shop3: it has none
06:28 PM rue_shop3: causes it all sorts of problems
06:48 PM rue_shop3: tom, ok, legs are comming togethor
06:48 PM rue_shop3: wondering how to mount the springs
07:03 PM Tom_L: U bolts
07:03 PM Tom_L: or body washers with a bolt but you'd wanna tack the washer to the spring
07:04 PM Tom_L: without losing the temper on the spring
07:14 PM rue_shop3: hahah the motor runs backwards and its series wound
07:14 PM rue_shop3: their compression springs, hows a U bolt supposed to work?
07:25 PM rue_shop3: it shakes!
07:41 PM Tom_L: one on each end
07:52 PM rue_shop3: er, ok
07:52 PM rue_shop3: I"ll post the images, I just need to do a water system for it later then
07:53 PM rue_shop3: its sensitive about the speed of the motor, the tumble will actually reverse at the wrong speed
07:53 PM Tom_L: https://www.mcmaster.com/#tumbling-media/=1dvg37m
07:53 PM rue_shop3: no I just used lava rock
07:53 PM Tom_L: is it too coarse for aluminum?
07:53 PM rue_shop3: tom, I cant get real industral stuff here, esp with the money I ahve to spend on it
07:53 PM rue_shop3: I"ll show ya the video
07:53 PM Tom_L: i just wondered if it works
07:53 PM Tom_L: they use walnut shells to polish
07:54 PM rue_shop3: ? in a vibration finisher?
07:54 PM rue_shop3: I know of it used in sand balsters
07:55 PM Tom_L: unless i start making alot of parts, i'm not going to make one
07:56 PM Tom_L: you might want to take some of the weight off your vibrator
07:56 PM Tom_L: .... get a bunch of pager motors and mount to the outside :D
07:58 PM rue_: dude it ust needs paint, its finished
07:58 PM rue_: http://ruemohr.org/~ircjunk/projects/finisher/p1100378.jpg
07:58 PM rue_: http://ruemohr.org/~ircjunk/projects/finisher/p1100379.jpg
07:58 PM rue_: I'll psot the youtube video
07:59 PM rue_: I want bets on which tack welds will break first
07:59 PM rue_: Tom_L, so? you gonna build one?
08:01 PM rue_: does it give you any ideas?
08:02 PM Tom_L: you didn't read what i said
08:03 PM Tom_L: <Tom_L> unless i start making alot of parts, i'm not going to make one
08:04 PM Tom_L: looks good
08:04 PM rue_shop3: ugh
08:04 PM rue_shop3: but.... but...
08:05 PM Tom_L: when did you get a miller welder?
08:05 PM Tom_L: is that the tig?
08:07 PM rue_shop3: ..
08:07 PM rue_shop3: .
08:07 PM rue_shop3: .
08:07 PM rue_shop3: .
08:07 PM rue_shop3: <Tom_L> huh, i could add the engraving tool and use it as a chamfer / debur
08:07 PM rue_shop3: <Tom_L> i need a vibra-tumbler now
08:07 PM rue_shop3: <Tom_L> ok, conquer the world whilst i sleep. gnite
08:07 PM rue_shop3: .
08:07 PM rue_shop3: .
08:07 PM Tom_L: it was a wishful list
08:08 PM rue_shop3: ... ok, world conquered... what do you mean by "retorical comment"
08:08 PM rue_shop3: BUT I MADE ONE IN LESS THAN 48 HOURS
08:08 PM rue_shop3: it cost me _$20_
08:08 PM rue_shop3: I WILL NEVER GET THAT $20 BACK!!!!
08:08 PM Tom_L: yeah, nice job
08:08 PM * rue_shop3 bangs his head on the desk
08:09 PM Tom_L: but you needed one too
08:09 PM Tom_L: how's the can holder project goin?
08:10 PM rue_shop3: oh we (the other fellow) did an order of 12 and just got it out
08:10 PM rue_shop3: so were just restocking parts (in reality, trying to remeber how to make them)
08:13 PM Tom_L: i'm just programming parts
08:13 PM Tom_L: when i get time i need to cut some more blocks to size
08:14 PM rue_shop3: oops, I think that was over what the motor could do
08:14 PM Tom_L: burn it out?
08:14 PM rue_shop3: dunno, its burning hot, I think a thermal kicked in
08:14 PM rue_shop3: I'll wait and see
08:15 PM Tom_L: my cooler works great
08:15 PM rue_shop3: if I redo it, I'll isolate the vibrator and use a belt drive
08:15 PM Tom_L: i fill the bucket with water and dump ice in it
08:15 PM rue_shop3: the mass of the motor threw it all out
08:15 PM Tom_L: i could get a tiny radiator
08:15 PM Tom_L: 120mm fan
08:16 PM rue_shop3: or much larger motor and a belt drive
08:17 PM Tom_L: i'd like that but finding one i can control isn't easy
08:17 PM Tom_L: the spindle seems to do fine
08:18 PM rue_shop3: I think the brushless washing machine motors are 1.5Hp
08:18 PM Tom_L: did you ever wear the bearings out in the sherline?
08:18 PM rue_shop3: but you would have to do some coding and re-brain the controller
08:18 PM rue_shop3: no, bearings are all fine
08:18 PM Tom_L: i thought you had bearings go out on one
08:18 PM rue_shop3: had to do the motor brushes, armyofevilrobots said that he never had, and not to worry about it
08:19 PM rue_shop3: its on loan
08:19 PM Tom_L: i know
08:19 PM rue_shop3: the bearings went on my mill
08:19 PM rue_shop3: the spindle
08:19 PM Tom_L: oh
08:19 PM rue_shop3: its a bad design, the wedge hole gives access to drop chips directly into the unsealed ball bearings
08:19 PM Tom_L: this part is gonna take a long time to machine
08:20 PM Tom_L: but maybe it can run un-attended a bit since i'm fixing the paths
08:21 PM rue_shop3: by now you should know if your machine is gonna blow up on ya
08:21 PM rue_shop3: I'm fine with all the machies now
08:21 PM Tom_L: it's solid
08:21 PM rue_shop3: when I finish the new pritner, I'll watch it for 48 hours or so
08:22 PM Tom_L: this will have 5 positions
08:26 PM Tom_L: i don't think i'm gonna do a lightening pocket
08:26 PM Tom_L: hollow out the bottom...
08:27 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Skate_truck/Skate_truck3.jpg
08:27 PM Tom_L: i gotta angle the ends to put holes in those angled flats on each end
08:28 PM rue_shop3: I love skelatonized stuff
08:28 PM Tom_L: takes too long
08:28 PM Tom_L: and i may need a larger cutter to get the right depth
08:29 PM Tom_L: it's over the 1/8" cutter's cutting length
08:29 PM Tom_L: i did the pockets on the bottom for the bolt heads though on those 2 larger holes
09:25 PM rue_shop3: the motor is ok, turns out the charger couldn't keep up with the motor draw and the battery dropped a cell
09:27 PM Tom_L: good
09:27 PM Tom_L: something like that probably should have an AC motor
09:27 PM Tom_L: since it will run a while
09:31 PM rue_shop3: but needs speed control
09:31 PM Tom_L: ok 35 deg
09:31 PM Tom_L: had to boot into 64bit to see the original model
09:41 PM rue_shop3: the smallest thing change the way it tumbles
09:41 PM Tom_L: there may be more to them than meets the eye
09:42 PM Tom_L: for what i do i think if i make one it will be a simple barrel roller
09:42 PM Tom_L: like a rock tumbler
09:56 PM rue_shop3: vibra-tumber ate my small parts..... .com?
09:56 PM Tom_L: if you leave them in too long :)
09:57 PM Tom_L: i wish i had a sin plate
09:57 PM Tom_L: gotta cut a 3 deg backing plate to hold the part at the angle
09:57 PM Tom_L: 35 deg
09:58 PM furrywolf: I'd be worried if my vibrators tried eating my small parts...
09:58 PM zhanx: are they names buzz and woody?
09:59 PM Tom_L: hmm, i could make one and bolt it to my sacrificial plate at the right angle...
10:00 PM zhanx: Tom_L, just shim your 123 block for it
10:00 PM zhanx: wait do you have a threaded 123 block for that?
10:00 PM Tom_L: i gotta hold it in several places, that may not work
10:01 PM Tom_L: i have threaded 123 blocks yes
10:01 PM rue_shop3: Tom_L, I'm not doing a sine plate, look what I eneded up with last time you got me on a project
10:02 PM zhanx: been awhile but they are made to do that also
10:02 PM Tom_L: but you needed one rue_
10:02 PM Tom_L: they are?
10:02 PM rue_shop3: not enough to build one, you tipped the scale
10:02 PM rue_shop3: I half made it so you would have a design ref
10:02 PM zhanx: yea the different threads with a stopper allow angles on them, last time i did it was like 94,95
10:03 PM rue_shop3: furrywolf, it took me like 6 mins of digging to find my part
10:04 PM Tom_L: zhanx, i don't quite follow how you would do that
10:04 PM Tom_L: i'm gonna hold the part in the vise at the angle at this point
10:05 PM Tom_L: unless i come up with a simpler solution
10:05 PM zhanx: triangle math, really. but i think all my hold downs were magnetic at that place
10:08 PM rue_shop3: ok, I was excited to be finsihed this so I could start the....
10:08 PM rue_shop3: needed to code for it....
10:08 PM Tom_L: oh wait i need one of these too .....
10:09 PM Tom_L: i bet rue could make one..
10:09 PM zhanx: if he had time
10:14 PM rue_shop3: hah, with the new feed rates that part that took 4 hours takes 48 mins
10:14 PM rue_shop3: if I had coolant it'd be less
10:15 PM zhanx: time to get a cheap pump and add it
10:16 PM Tom_L: i mix a gal at a time and just use that cheap mister
10:16 PM Tom_L: works great
10:17 PM Tom_L: lose quite a bit in the chips but i try to drain them
10:18 PM Tom_L: one of my first jobs had a huge metal spinner to reclaim the cutting oil
10:18 PM Tom_L: ahh that's it!!! rue you need a metal spinner now
10:18 PM Tom_L: i could toss em in the washer but i bet she would frown on that
10:19 PM zhanx: more stuff for rue to make
10:20 PM furrywolf: I got an air+coolant mister setup thingy, but haven't used it yet
10:21 PM rue_shop3: hahahah
10:21 PM rue_shop3: furrywolf, yea, I got one too
10:21 PM rue_shop3: did you see toms?
10:22 PM rue_shop3: he uses his continious
10:22 PM rue_shop3: I just have a air puff thing on my machines
10:22 PM rue_shop3: I dont ahve large enough compressors to do continious
10:24 PM furrywolf: https://cdn.mscdirect.com/global/images/ProductImages/0942100-24.jpg I got that one, with the shiny stainless tank
10:24 PM rue_shop3: Secure Connection Failed
10:24 PM rue_shop3: An error occurred during a connection to cdn.mscdirect.com. Cannot communicate securely with peer: no common encryption algorithm(s).
10:24 PM rue_shop3: }:|
10:25 PM rue_shop3: I have to hack my own connection so I can browse the freaking web
10:27 PM furrywolf: http://d2j6tswx2otu6e.cloudfront.net/R3-GtJj95_57YgKdrgFxtyZsqZU=/600x801/10c8/10c8e601737741998edce2db41f86f39.jpg (random used one, first one I could find that worked with http)
10:33 PM rue_shop3: oo
10:33 PM rue_shop3: huh
10:33 PM rue_shop3: I could make one of those
10:33 PM rue_shop3: WAIT A MIN
10:34 PM rue_shop3: I have other things to do
10:34 PM * rue_shop3 takes a tape meausre and goes back to the large ring by the 12' robot
10:34 PM Tom_L: those cheap chinese sprayers work but you need to add another o-ring to keep the end from vibrating off
10:37 PM rue_shop3: ok I get 278cm of usefull arc from each peice
10:37 PM rue_shop3: the outter dia of the ring is...
10:37 PM rue_shop3: er circ.
10:37 PM Tom_L: mark a chalk line in the dirt and roll the ring down the hill and measure it
10:38 PM rue_shop3: the outter circumfrance is about 839cm
10:39 PM rue_shop3: so just about bang on 3 pieces per ring
10:39 PM rue_shop3: so I need 6 peices
10:39 PM rue_shop3: I have...
10:39 PM rue_shop3: ok I have 5
10:40 PM rue_shop3: to the bender!
10:43 PM rue_shop3: that leaves 4 peices in stock, that means there was a moderate error in my origional math
10:43 PM zhanx: for a second i read that as too the blender!
10:43 PM rue_shop3: I'm not sure if that was supposed to be enough for 2 rings or not
10:43 PM rue_shop3: I think I wanted to make two of these, and sell one for funds recovery
10:46 PM Tom_L: you could hang one from the celing and use it as a clothes rack
11:12 PM rue_shop3: https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQ61isUfY__m6xk5aOZlFp137oxqNApzOGWqb4lqm-oGylEffwB
11:12 PM rue_shop3: ??
11:12 PM rue_shop3: how now brown cow?
11:14 PM rue_shop3: http://ruemohr.org/~ircjunk/robots/sparrow1/p1100158.jpg
11:14 PM rue_shop3: your following, right?
11:15 PM rue_shop3: arg, where are the new images
11:17 PM rue_shop3: ugh, and now the inevitable problem, I have nowehre to put this damn finisher
11:17 PM rue_shop3: that didn't stop me from building the 3d printer thats been occupying the soldering station for about 6 months now
11:35 PM furrywolf: bbl, wolfy bedtime
11:47 PM rue_shop4: gngiht
