03:31 AM -!- #linuxcnc-devel mode set to +v by ChanServ
08:49 AM skunkworks: cradek, first I will say - There is a button to take a snapshot? Cool. No - I never figured it out. (didn't try obviously)
09:35 AM hazzy: cradek: Well, after you mentioned the "supereyes" I looked it up to see what is was, and I guess I ended up buying one in the wee hours.
09:35 AM hazzy: I have a conformation email at least ...
09:35 AM archivist: too much beer?
09:38 AM hazzy: No, I actual did not drink anything last night but a bunch of coffee, but it had been a long day and I guess I was just half asleep lol
09:39 AM archivist: I use stereo microscopes rather than cameras
09:41 AM skunkworks: for the price - it is a pretty nice camera - it will focus from 0 to infinity...
09:43 AM archivist: just took a pocket watch apart, cannot see how the mainspring arbour comes apart to get it out and fix
09:55 AM hazzy: archivist: Stereo microscopes are great! I have several that I keep set up in my various work areas so I don't have to walk too far
10:00 AM skunkworks: I used hte camera to play around with vision https://www.youtube.com/watch?v=Pe2RACwiEbg
10:01 AM archivist: hazzy, I have one over the lathe for hand turning small stuff
10:03 AM hazzy: skun
10:03 AM hazzy: skunkworks: That is pretty neat!
10:05 AM hazzy: Might you happen to have the code for that laying around anymore?
10:10 AM skunkworks: I think so - it used ummm opencv with python
10:41 AM cradek: archivist: the idea is to make the camera fit onto one of the eyepieces on my (stereo) microscope
10:43 AM archivist: I have used a camera down the eyepiece to get images of some worn pivots
10:43 AM cradek: archivist: what's weird about it?
10:43 AM archivist: the watch?
10:43 AM cradek: yeah the mainspring arbor
10:44 AM archivist: cannot see the join, this style http://static.flickr.com/110/307311934_0064baa55b_b.jpg
10:45 AM archivist: there is a ratchet wheel on top and the spring centre under no sign of screw/ whatever to get it off the bar and barrel outer
10:45 AM cradek: I love those swiss bars, where you only have to put in one wheel at a time
10:46 AM archivist: the ratchet wheel has some broken teeth and its not holding
10:47 AM cradek: the ratchet doesn't just lift off the winding square?
10:47 AM archivist: cylinder and escapement and dial are all ok so seemed worth fixing for a giggle
10:47 AM cradek: I guess I can't picture what you're saying
10:48 AM archivist: I cannot see a gap for it to come off and it retains the barrel
10:48 AM cradek: heh I saw this one and said to myself - he's lucky, at least it's not a cylinder
10:48 AM archivist: I have a soft spot for cylinders :)
10:49 AM cradek: haha I have a total hard spot. won't touch them.
10:49 AM archivist: bottom looks like http://ihc185.infopop.cc/eve/forums/a/ga/ul/9901081022/inlineimg/Y/Geneva_Stop_Work.jpg
10:49 AM cradek: with a fusee they might even sorta keep time, but I don't think anyone ever did that
10:49 AM archivist: except the hole for the taper pin is buggered
10:50 AM archivist: the bar and mainspring assembly is crude on these
10:50 AM cradek: usually all the parts are crude on those...
10:51 AM cradek: I wish I had taken the pictures last night to show you what I'm doing on mine (just a staff replacement)
10:52 AM archivist: still ticks dunno about all the walthams and elgins in the bit boxes :)
10:53 AM archivist: I could take a couple of pics of this awkward bit
11:07 AM archivist: cradek, http://www.collection.archivist.info/searchv13.php?searchstr=bar+swiss+PD
11:12 AM skunkworks: does the square unscrew?
11:13 AM archivist: I have tried unscrewing and it feels very solid
11:14 AM archivist: the bar cannot take any pressing force it is very thin in the middle
11:15 AM archivist: as there is no rear bearing they use something in that arbour to hold it
11:15 AM archivist: may be that is the taper pin that is supposed to have been there
11:31 AM cradek: I'm pretty sure it unscrews
11:31 AM cradek: it would be a righthand thread, right?
11:32 AM archivist: the ratchet is left so I tried right
11:32 AM cradek: what part were you holding when you tried unscrewing it?
11:33 AM archivist: the mainspring disk/hook
11:33 AM cradek: hmm I do think that should work
11:33 AM archivist: but cannot see a sign of the thread
11:34 AM archivist: as the teeth are broken and the taper pin hole is damaged may just have to cut it out, I am wondering if a clown glued it
11:35 AM cradek: center: http://www.abbeyclock.com/gbk/gbk/4.jpg
11:36 AM cradek: "hanging barrel" is a good search term
11:36 AM archivist: I had been searching swiss bar mainspring arbour
11:38 AM cradek: https://mb.nawcc.org/threads/swiss-mainspring-arbor-barrel-removal.30136/
11:38 AM cradek: unfortunately the photo is gone, but this also says you unscrew it
11:39 AM cradek: you could try a little heat if you have to remake the parts anyway
11:41 AM cradek: although it seems like you could keep your hook part if you can get it apart and then match the thread
11:41 AM cradek: but I want to know how on earth did someone break out the taper hole?
11:41 AM archivist: that picture made all the difference, it came apart
11:41 AM cradek: sweet!
11:41 AM cradek: do you still have the stop work?
11:42 AM archivist: yes
11:42 AM cradek: cool. those seem to "get lost" a lot
11:42 AM archivist: was hanging on precariously
11:55 AM archivist: hmm, could be kludge time, just file up the teeth
11:56 AM cradek: and then harden it properly like wasn't done before?
11:57 AM cradek: but the click won't reach then will it?
11:59 AM archivist: looks like the bar slot is not formed properly thus causing part of the problem, also the pin that keeps the click inline was missing and was not screwed up tight
12:00 PM archivist: the teeth were full of brass chips also stopping the click from full depth
12:01 PM archivist: couple of bad teeth, rest not so bad
12:08 PM cradek: would love to see your result
12:15 PM archivist: trying to find a nice way of holding it
01:38 PM archivist: cradek, trial assembly with new pin in the click and teeth and slot filed feels like its a runner
01:47 PM cradek: neat, that was easy!
01:47 PM cradek: are you going to harden the clickwheel?
07:12 PM andypugh: Boo Hoo! It’s too hard, you shouldnt make me edit text files and understand my hardware….
07:14 PM skunkworks: elitist...
07:40 PM hazzy: LOL, just read that
07:41 PM hazzy: if you can't recognize that 1w4r is not a valid number then you prolly should not be operating a machine tool
07:47 PM skunkworks: JohnD had asked me off list about how hard it is to setup a simple shortcut to launch machinekit with a given config. he said the config picker doesn't have the 'create shortcut icon' and right clicking on the doesn't allow him to add the ini path to the command. seems odd. I told him I probably would not have started with machinekit
08:24 PM hazzy: skunkworks: Would a standard desktop entry file not work?
08:31 PM hazzy: One of my many LCNC shortcuts: https://thepasteb.in/p/g5hPZRw8VKOIr
08:39 PM hazzy: maybe I like editing those text files too much ;)
09:00 PM skunkworks: heh
09:04 PM hazzy: ??
09:04 PM hazzy: or does he not think a desktop entry is simple enough
