12:03 AM rue_mohr: http://imperiya.by/image/lZjMqlUJXIx.jpg
12:03 AM rue_mohr: I have to wonder, how much of festos pneumatic engineers were involved in that one
12:03 AM rue_mohr: and what about those disney actuators
12:03 AM * rue_mohr puts a chart on the wall and points to it, "basic lack of focus"
12:03 AM katsmeow: that's a contraption to push fingersinstead of tendons to pull them
12:04 AM rue_mohr: I think their doubleacting
12:04 AM rue_mohr: but it looks "thick" and the joints look clumbsy
12:04 AM rue_mohr: and there is a missing/broken joint
12:05 AM katsmeow: A HA!
12:05 AM katsmeow: that fictional townin that movie was named after WhaHacka, which is a town/valley in Mexico
12:06 AM rue_mohr: ok
12:07 AM katsmeow: Wahaka may refer to:
12:07 AM katsmeow: The phonetic pronunciation of the state of Oaxaca in Mexico
12:07 AM * rue_mohr , like a fridge compressor failing to start, tries to focus again... "bbzzzzzzz *tick*"

12:19 AM katsmeow: we have a word, spelled and pronounced correctly, to say "did wear before now" : wore
12:20 AM katsmeow: why are so many people nowadays saying "war" like "wore"? "war" is aperfectly good word, that is unambiguously not about what one did wear yesterday
12:33 AM katsmeow: https://www.ebay.com/itm/Electric-Solenoid-Valve-For-Water-Purifier-Refrigerator-Normally-Closed-DC-12V/141748262529
12:34 AM katsmeow: https://www.ebay.com/itm/New-Solid-100PSI-DC-12V-4L-Min-Diaphragm-Water-Self-Priming-Pump-High-Pressure/181392820089
12:34 AM zhanx: got that last link
12:34 AM zhanx: it sucks
12:35 AM katsmeow: ihave not tried the open frame motors, but i have several small ones like that
12:35 AM zhanx: i have to tap it get it to start
12:35 AM katsmeow: it's self priming, isn;t it supposed to suck ?
12:35 AM zhanx: and i can stop the output with my thumb easy
12:36 AM zhanx: but it does fill the fish tank fast
12:36 AM katsmeow: open it up and clean the diaphrams
12:36 AM zhanx: only use it to pump water from the tub to the fish tank
12:36 AM katsmeow: fish tank water is dirty enough to mess with them
12:36 AM katsmeow: k
12:37 AM zhanx: i siphon the tank
12:37 AM zhanx: clear the hose and then use that pump, but for the price i can't really complain
12:38 AM katsmeow: i figured rue could use it to power the mecha's fingers
12:39 AM zhanx: well i know i can run on 12v 1 amp
12:39 AM zhanx: pump 45 gallons of water in 30 minutes, but i have to wack it to start it
12:40 AM zhanx: and will work to 6 feet of head pressure if i prime the lines
12:41 AM katsmeow: my 120vac one was pricey, usa made, pumps from 70ft down at the creek, can do 1000 gallons/day
12:41 AM zhanx: my well pump is close to that
12:42 AM katsmeow: is it a baby pump too ?
12:42 AM zhanx: no its 240vac three phase
12:43 AM zhanx: 150 feet to the point in the well
12:45 AM katsmeow: this looks like the one i run at the creek : https://www.ebay.com/itm/SHURflo-pump-8000-812-288-diaphram-on-demand-pump/382423186702
12:45 AM katsmeow: i have 120vac down there, don;t wanna carry a 12v down there
12:47 AM katsmeow: i wanted to leave it down there, but i couldn;t work out a foolproof way to keep theplumbing to the creek from freezing, and be self-priming without me going downt here
12:50 AM zhanx: mine is close to this one but deep well https://www.tractorsupply.com/tsc/product/countyline-convertible-cast-iron-jet-pump-1-2-hp
12:52 AM katsmeow: i have a big one like that on the pressure tank in the cellar, it pulls from either/or the big pool-tank outside or the 500 gal pool-tank inside
12:53 AM zhanx: i need another one for the garden, will be a small one like your link
12:53 AM zhanx: so i can pump from the creek
12:54 AM zhanx: but next year
12:56 AM katsmeow: cannot find mine on the homedepot site, i guess they quit carryingit
12:57 AM katsmeow: had to work out a way to prime the idiot thing too, if it is not 100% full of water, it will ot pump
12:57 AM zhanx: gave up looking for mine, i only put it in this winter
01:01 AM katsmeow: btw, pool plumbing is much better flow than regular water plumbing, when it comes to check valves and ball valves
01:02 AM katsmeow: the check valve to the pressure tank is prolly 3" dia pvc, was cheaper than any brass valve, and no troubles the last 5(?) years
01:03 AM katsmeow: was in the pool dept
01:07 AM katsmeow: neighbor's place yesterday :

07:51 PM rue_mohr: hmm
10:06 PM rue_shop3: 8-S ok, I put a switch on the pipe bender, .... should I try to bend some pipe now?

10:20 PM katsmeow: http://tinyurl.com/y9fpx5dw

10:52 PM katsmeow: got video of the pipe bender?
10:53 PM rue_mohr: YES
10:53 PM rue_mohr: (working on it)
10:53 PM rue_mohr: ... just let me edit in a pipe..... :)
10:54 PM rue_mohr: if I'd made my welding-thing helper, I'd have had the cameramn that I needed
11:03 PM rue_mohr: https://youtu.be/fFQvuijcwlM
11:08 PM katsmeow: that's cheating, you used a pip that was already bent
11:14 PM * katsmeow looks at rue
11:15 PM rue_mohr: I did that in about 15 stages
11:15 PM rue_mohr: I need a way to work out the radius
11:15 PM rue_mohr: and I NEED A LARGER TABLE
11:15 PM rue_mohr: a much larger table
11:16 PM katsmeow: portable tables, to account for different bends
11:16 PM rue_mohr: I am super pleased
11:16 PM rue_mohr: I should have a stalled-cutout, stalled it twice
11:16 PM katsmeow: i would be also
11:17 PM rue_mohr: the other surprise was not needing a wrench to tighten it, when the pipe it out, its loose and can be given __1/4 turn only__ by hand
11:17 PM katsmeow: are you accepting feedback on it being too noisy in the video, or the wrong color? wrong voltage?
11:18 PM rue_mohr: sure, whatever, it works
11:18 PM rue_mohr: I kinda like the sound
11:18 PM katsmeow: ( there is no sound in the video )
11:19 PM rue_mohr: there is, its noisy
11:19 PM rue_mohr: the bend comes out like its hydraulic too
11:21 PM katsmeow: wierd, played it back the 5th time got audio!
11:24 PM rue_mohr: https://www.youtube.com/watch?v=FO6My1joJVc
11:24 PM rue_mohr: you following this guy
11:26 PM katsmeow: no?
11:26 PM katsmeow: actually, not following anyone
11:26 PM rue_mohr: didn't mean itnernet following, just watching for new videos
11:27 PM katsmeow: i muted and stopped that video 4 sec in, due to the yelling
11:28 PM katsmeow: looks like he is nto torturing dolls, is that all ?
11:29 PM katsmeow: caution, i ate sinus pillsand sleeping pills
11:32 PM katsmeow: "it's a gated community, with 24-7 armed patrols. it's a jail"
11:35 PM rue_mohr: ok, so, my pipe bender works
11:35 PM rue_mohr: let me post a better pic
11:36 PM * katsmeow congrats rue again, with special cong rats
11:37 PM rue_mohr: http://ruemohr.org/~ircjunk/robots/sparrow1/p1090982.jpg
11:37 PM rue_mohr: high res of the pipe
11:38 PM katsmeow: sweet curves
11:39 PM rue_mohr: I need to work out what the ring dia's are supposed to be
11:39 PM katsmeow: yeas, because unbending them usually fails
11:39 PM zhanx: the ones you make the last time of course
11:39 PM katsmeow: afk to change shoes
11:39 PM rue_mohr: its a gyro set
11:40 PM rue_mohr: er gimbal set
11:40 PM zhanx: k
11:40 PM rue_mohr: for an "austronaut trainer'
11:40 PM zhanx: 10% reduction right
11:40 PM rue_mohr: ?
11:40 PM zhanx: from outer to each inner ring its a 10% reduction in size
11:41 PM rue_mohr: oh? I'z gonna gap it 3"
11:41 PM zhanx: might work out the same with that
11:41 PM rue_mohr: where does the 10% come from
11:41 PM zhanx: or close
11:41 PM rue_mohr: I need to fit a human in the inner ring
11:41 PM zhanx: not a clue its something that stood out in my brain on gimbal sets
11:41 PM rue_mohr: that can flail without hitting it
11:42 PM zhanx: so start with the inner ring
11:42 PM rue_mohr: yea
11:42 PM zhanx: leg span plus error room
11:42 PM rue_mohr: that one is *close* to an 8' dia
11:42 PM zhanx: for you
11:48 PM katsmeow: back
11:54 PM rue_mohr: :)) pipe bender works
11:54 PM rue_mohr: I can make the rings
11:55 PM rue_mohr: but I dont have the force feedback suit ready
11:55 PM katsmeow: you need someone to force you to make it?
11:55 PM rue_mohr: the plan is to make two of the gyro cages, sell one for project funds
11:55 PM rue_mohr: heh
11:56 PM rue_mohr: in theroy I can make other dies for it too
11:57 PM katsmeow: so i now have some 4ft scraps of 4" steel tube, 1/4 wall, to make uprights for a milling machine, howmuch vertical movement does the mill head need? 2ft?
11:57 PM rue_mohr: I'm gonna need motors to operate the rings
11:57 PM katsmeow: why would i have something 2ft thick i need tomill?
11:58 PM rue_mohr: when I made my last machine, I just gave in, and only gave it about 2"
11:58 PM rue_mohr: almost EVERYTHING I do is profile cutouts
11:58 PM katsmeow: my pcb driller was accurate only 1/4 inch travel
11:59 PM katsmeow: that said, the vertical travel was tighter than the runoutin any bearings i had
