03:12 katsmeow The twenty-three accidents listed below involving U.S., Soviet, and Russian nuclear weapons or nuclear- armed ships and submarines are some of the more serious nuclear accidents to befall U.S. and Soviet nuclear forces. As a result of accidents, some 51 nuclear warheads were lost into sea (44 Soviet and 7 U.S - although at least one Soviet warhead was recovered).
03:12 katsmeow Also, seven nuclear reactors (5 Soviet and 2 U.S.) from three Soviet and two U.S. nuclear-powered submarines have been lost at sea due to accidents. Another 19 nuclear reactors from nuclear-powered vessels have been deliberately dumped at sea (18 Soviet and 1 U.S.).
12:47 rue_house just think, thats maybe 25 nuclear plants that could be in peoples back yards powering their town
12:47 rue_house my understanding is: u salvage, u own
12:48 Tom_itx you gonna salvage a nuke plant now?
12:50 Tom_itx so what did the kids do yesterday?
12:51 rue_house it was just me
12:51 rue_house the new one didn't show, the regular called in
12:51 rue_house ...
12:51 rue_house time for a new batch?
12:51 Tom_itx yep, the old batch is getttin stale
12:54 rue_shop2 have to wind up all my material again
12:55 Tom_itx rif is sure full of gusto now
12:55 rue_shop2 never did get the 3 at once to do a unified project with one doing electronics, one with mechanics and one with programming
12:55 rue_shop2 yes, he's doing neato stuff
12:55 Tom_itx shame he won't learn the low level stuff
12:55 rue_shop2 if he can just put a little more value on learning to program
12:55 Tom_itx seems he's got a handle on his lib
12:55 rue_shop2 good
12:56 Tom_itx what was that color sensor for?
12:56 rue_shop2 it takes a while to get the swing of how a particular author writes informaion on their stuff
12:56 rue_shop2 I think its just to
12:56 rue_shop2 like my screens
12:57 Tom_itx i wanna wire up all this washer stuff and test that serial link to the motor driver soon
12:57 Tom_itx then get an avr to do it
12:57 Tom_itx with a pot or something
13:20 katsmeow you can't salvage a nuke plant, it's military, and the military almost never un-owns anything, they just disavow responsibility for that damage it does
13:23 katsmeow not sure about the status of ww1 and 2 german wrecks, since officially the country that built them no longer exists, and since ww1/2 the usa has done whatever they please to german war wrecks
13:23 katsmeow ~10 yrs ago a oil well platform hit a sub, they took picks, partially raised it, and then towed it to deeper water and re-sank it
13:24 katsmeow the usa nuke wreck off the Azores, and maybe the one closer to the usa, has proximity sonar alarms around
13:27 katsmeow Iran has announced it's intention to plant nuke on the bottom anywhere a major usa warship might go
13:27 katsmeow but i can imagine Iran and N Korea are interested in where those bombs are
13:28 rue_shop2 ok I took a pipe, and with the carrige set the same on both ends, turned a piece of pipe down a bit, on the head end I get 21.2mm on the tail end I get 20.63mm
13:28 katsmeow if all they want is dirty bomb material , it's well known that UK has a nuke dump off their shores, and the usa once used one off Califonica
13:29 rue_shop2 so, the tailstock is too far forward to the carrige by
13:29 rue_shop2 .57/2?
13:29 katsmeow 61/2
13:29 katsmeow oops
13:30 tsmeow has too much on her
15:50 rue_house !assist circuits
15:50 tobbor Possibly http://eds.dyndns.org/~ircjunk/circuits
15:51 katsmeow ?
15:54 tsmeow resets the clock of rue doing something or other about the kline and #RoboTics,,, resetting it to "will never hap
15:55 tsmeow-afk just isn't wort
16:13 rue_house this has happened twice to me, I have a 5 spoke thing I need to fit in the 3 jaw chuck...
17:09 Tom_itx that's what 4 jaw is for
18:08 rue_house how you gonna put a 4 jaw on the inside of a wheel with 5 spokes?
18:09 Tom_itx what?
18:10 rue_house its the sprocket from the pedal axle of a bike
18:10 rue_house its got 5 sprockets
18:10 rue_house er spokes
18:20 Tom_itx bolt it to a backing plate
18:28 katsmeow-afk turn a shaft that fits the id of the sprocket, tap it for a bolt, and an offset pin, chuck the shaft, slip on the sprocket, bolt on a large washer to clamp it
18:29 katsmeow-afk you can even use a portion of the bike crank to make the shaft from, it's already threaded, maybe keyed
18:29 katsmeow-afk but yeas, like Tom said, flat plates are the fasten-everything jig of lathes
18:30 katsmeow-afk you can even get them (i have two) with T-slots in them for mill bed attachments
18:30 katsmeow-afk and you can always (if you're good) remove the bolt-on jaws that came with it, and bolt on some otehr attachment method
18:31 katsmeow-afk push come to shove, use the tailpiece to push and hold the sprocket to a set of pins in the faceplate
18:32 katsmeow-afk nother trick would be to cut the OD of the sprocket into the ID of a pipe that you then insert the sprocket into and clamp that all up in the lathe, any number of jaws
18:34 katsmeow-afk i'd prolly go with making a shaft to fit the sprocket, chuck that up, and bolt the sprocket to or mash tight with the tailstock, and use a pin as a dog on the faceplate
18:35 katsmeow-afk you don't need much pin, a 3/16 will make for a lot of torque 3 inches out from the centerline

18:52 katsmeow-afk else i would know about that formula
19:39 katsmeow-afk sixty, seventy, eightty, ninety, tenty, eleventy, twelvety,......
20:41 rue_shop2 I found the washers!
20:42 katsmeow-afk congrats!
20:42 rue_shop2 hows your day been going?
20:42 rue_shop2 working over digitized data?
20:43 rue_shop2 I was able to use the drafting program to come up with a template to find the 'approx' centre of the sprocket
20:43 katsmeow-afk really slowly, i did finally get the grape vine freed, by removing the tree and the honeyskunkle
20:43 katsmeow-afk the approx center isn't the center of the hole?
20:43 rue_shop2 well it wasn't by lathe, it was but punch and press
20:44 katsmeow-afk btw, anotehr way: chuck the center hole of the sprocket in a mini-chuck, and then chuck the mini-chuck in a normal lathe chuck
20:46 katsmeow-afk this one can grip the inside of the crank hole : http://www.harborfreight.com/2-inch-mini-lathe-chuck-with-mt-2-shank-4486.html
20:47 rue_shop2 its the sprocket on the pedals, there isn't a centre hole, just 5 short spokes
20:47 katsmeow-afk here's a cheap 4-jaw that's easy to change the jaws on : http://www.harborfreight.com/6-inch-wood-lathe-chuck-with-key-31223.html you can prolly clamp up his in your real chuck also
20:47 katsmeow-afk ummmm,,, all mine, cep the bolt-on sprockets for deraileurs, have center holes
20:48 rue_shop2 http://bike.shimano.com/publish/content/global_cycle/en/us/index/products/road/sora.image.-groupTextImage-Single-image.dash.jpeg
20:49 rue_shop2 see how on the big ones, they go to ... see?
20:49 katsmeow-afk here's anotehr trick that works on gears and sprockets: put a section of chain or gear pieces tween the jaw and the sprocket or gear, so the jaws grip pressure is where business occurs
20:49 rue_shop2 cant really fit 4 or 3 jaw in there
20:49 rue_shop2 too big for my lathe to grab by the outside
20:49 katsmeow-afk o that is ugly
20:50 katsmeow-afk you cannot flip your jaws over so they clamp presure inwards?
20:50 rue_shop2 thats what I was trying, but you cant hit the same part in 3/4 places around
20:51 rue_shop2 I suppose I could duff with it a long time in the 4 jaw
20:51 katsmeow-afk no, use the pipe idea
20:51 katsmeow-afk the pipe spreads the jaw contact area off to many teeth
20:52 rue_shop2 hmm
20:52 katsmeow-afk on a derailur you don't necessarily want to clamp the tips the the teeth anyhow, remember it's meant to make it easy for he chain to be pushed off it
20:52 rue_shop2 its just for those large sprockets
20:52 katsmeow-afk wrap the sprocket in some scrap chain, then use the pipe idea to clamp with
20:53 e_shop2
20:53 katsmeow-afk the chain will let it clamp to the bottoms of the u^u^u^u^
20:53 katsmeow-afk v^v^v^
20:53 katsmeow-afk you know
20:53 rue_shop2 yup I get what you mean
20:55 katsmeow-afk the ultimate in custom holding to a lathe : https://en.wikipedia.org/wiki/Lathe_faceplate
20:55 rue_shop2 I have a plate, but centering it would take forever
20:56 katsmeow-afk if your chuck is sizeable, you can bolt up the faceplate to the work, and then chuck tha faceplate in the normal chuck
20:56 katsmeow-afk there hasto be a crank *shaft* for that funky pedal-sprocket to mount on, can't you make something using it?
20:58 katsmeow-afk unbolt the lil sprocket, using a turntable in the drill press, transfer the bolt pattern to anything you can chuck in the lathe, then bolt up the funky thing
20:59 katsmeow-afk don't really need the turntable, i spose
20:59 katsmeow-afk but a axle stub from the junkyard is ideal for this sorta thing
21:00 katsmeow-afk chuck in lathe, score a diameter where the bolt holes go, and presto, centered
21:03 katsmeow-afk http://designerthinking.com/images/carhub/i%20resurfaced%20it%20in%20place.jpg
21:03 rue_shop2 I needed a thin hub
21:03 katsmeow-afk but you need a rear drive axle, which will have something for the chuck to grab
21:04 katsmeow-afk it's surprisingly cheap steel, easy to cut to length, and then face off
21:04 rue_shop2 so I took a peice of plexigalss and bolted it over hte holes, but finding the center was what I wanted to do on the lathe, it turned out easier to just use the drafting program to draw out where the 5 bolts where, put an X on the middle, and print 1:1
21:04 katsmeow-afk drive cheap bolt into the holes, spot weld on the back, then face
21:05 katsmeow-afk or, make a set of bolt-on faces with custom holes
21:05 katsmeow-afk i turned and faced that flange with it on the car
21:06 katsmeow-afk it was bent : http://designerthinking.com/images/carhub/yep,%20it%27s%20bent.jpg
21:06 rue_shop2 ooo
21:06 rue_shop2 was that the one they used the sledge to take the axle out?
21:07 katsmeow-afk no, i had to use a 3-jaw wheel puller to force the axle out, to replace the axle
21:07 katsmeow-afk i dunno how they got it in there, but it didn't want out
21:07 rue_shop2 ah
21:07 katsmeow-afk the puller warped the flange
21:08 rue_shop2 I thought they just slide right out after you undo the clip
21:08 Tom_itx pressed on
21:08 Tom_itx or rusted
21:08 katsmeow-afk pulling the axle out with a tug from a sledge is an old trick when all that's holding it is a small compression C clip
21:09 Tom_itx i used to hook a chain on one of the lugs and give it a good snap
21:09 katsmeow-afk they are supposed to just about fall out once the bolt is off, maybe a lite tap with a hamemr
21:09 katsmeow-afk i use chain and 5lb sledge
21:10 rue_shop2 oh
21:11 katsmeow-afk but that one side absolutely refused to come apart,, if they pressed it, it was cocked or had debris in it, i had a lot of scrap swarf to clean out of the hub once i got the shaft out of it
21:12 katsmeow-afk i finally had to ink over the shaft splines and tap into the hub, then back out and drmel off the scratches in the ink
21:12 katsmeow-afk no problems at all with the otehr side, or the one rear i had to replace bearings on
21:13 rue_shop2 black green white red
21:16 rue_shop2 I have to sit down a work off a todo list on the truck
21:37 Tom_itx what's the truck need a list for?
21:42 rue_shop2 I told myself I would NOT pour a bunch of time into any vehicle
21:42 rue_shop2 I have better things to put my resources to
21:43 rue_shop2 arg, I have a sensor address conflict of soemthing
21:43 Tom_itx but if it has treated you well you should take care of it
21:44 rue_shop2 yes, but I'm not gonna pour a bunch of time into it
21:44 rue_shop2 its been worked out
21:44 Tom_itx what's wrong with it?
21:45 rue_shop2 lots of little things that aren't important now
21:45 Tom_itx is it time for me to sell my manuals?
21:45 rue_shop2 I'm trying to get a new sensor working on the boilet
21:45 rue_shop2 heh, maybe I should pay you to keep them :)
21:45 Tom_itx haha
21:45 rue_shop2 this is set to address 5, but when I plug it in, sensor 0 drops off the map
21:46 rue_shop2 101
21:47 rue_shop2 this should be 5
21:47 rue_shop2 damn, I do not want to build antoher philips interface to test this
23:12 rue_house the rock bed on the boiler completely fused again
23:12 rue_house had to pull out all the burning wood and ram it a few times as hard as I could with a crowbar
23:12 katsmeow-afk http://www.youtube.com/watch?v=V2WebXIuPYY&list=UUjTG9JMCE0o4IIkz8togf_w&index=154
23:37 rue_house YAY! my 1M $50 roll of vecro is canceled!
23:38 rue_house THE RESONANCE!!! CAREFULL!!!! THE RESONANCE!!!! YOUR APPROACHING THE RESONANCE!!!!!!!!!
23:42 katsmeow-afk why did you want a mile of velco?
23:42 Lola8088 meter
23:42 katsmeow-afk yeas, for several moments there he actually had over 6ft of water in a 2.5ft pool
23:50 katsmeow-afk something wierd going on, i have not recieved *any* emails on either account all day, not even any spam
