[09:01:23] <seb_kuzminsky> trentster1: you know the trick of turning the machine max velocity way down, when you're running gcode you're not sure what it'll do? it's saved me some end mills :-)
[09:28:55] <archivist> I recognise that Elgin site, was identifying some movements years ago
[10:09:21] <cradek> kwallace: cool - he's a friend from long ago and I hope he's doing well, wherever he is :-)
[10:10:07] <cradek> I got into machining because of watch work, and into cnc because of machining
[10:12:42] <archivist> I went into clockwork after machining, thence into cnc to make gear cutting easier
[10:26:43] <cradek> there's some neat stuff on his site: http://elginwatches.org/scans/tech_doc/bulletin_receiving_time_by_wireless/m_index.html

[10:29:07] <cradek> jepler: whee
[10:47:40] <kwallace> cradek: The last update on the Elgin website was ten years ago, so my next question was going to be "have you kept touch with Wayne, how is he doing?", but you answered that. The serial number database has been very handy.
[10:55:34] <kwallace> All my machines are too big for watch work and not that convenient for clocks. I need to get a lathe with WW collets. I have a junk AA109 that I could rebuild and modify for WW but it was junk when it was new -- cute but still junk.
[10:56:16] <archivist> you would be surprised how small you can work in a larger machine
[10:59:37] <cradek> I agree with that
[11:00:29] <kwallace> I have to start with 1/16th or 3/32nds stock because these are my smallest 5C collets. I'm out'a luck for work holding existing staffs. Or I'm not clever enough yet.
[11:01:55] <cradek> to hold existing staffs drill a hole in a piece of brass and fix the staff in it with shellac
[11:03:03] <cradek> spin it and center it with a toothpick as the shellac hardens
[11:03:58] <archivist> and then hand rest, graver and stereo zoom microscope
[11:04:00] <cradek> shellac will hold plates/cocks on a flat too, and you can center a hole the same way
[11:05:42] <cradek> for flats, a shape like this is easier to warm: http://www.ebay.com/itm/111839267437
[11:06:00] <cradek> the "tables" on mine are thinner than this
[11:06:13] <kwallace> I'll have to give that a try. I have seen videos by Steffen Pahlow where he uses shellac for work mounting, https://www.youtube.com/user/spahlow
[11:07:14] <cradek> for a staff, you don't really need to drill, just turn a divot with your graver. try hard to get it to come to a point at the center, and your staff will center very easily
[11:08:23] <cradek> am I misremembering, or do you have a sherline lathe?
[11:08:56] <archivist> I have used wooden chucks for gear, to machine the centre or rim on a barrel after the teeth are cut
[11:09:19] <kwallace> No Sherline here. HNC, Feeler and Zubal.
[11:10:05] <cradek> HNC would be a fine watch lathe :-)
[11:10:50] <kwallace> http://www.wallacecompany.com/machine_shop/index.html
[11:11:48] <kwallace> and: http://www.wallacecompany.com/machine_shop/Craftsman_AA_109/Craftsman_109-07a.jpg
[11:11:52] <cradek> I made a sherline spindle-shaped thing out of a 5C blank
[11:12:09] <cradek> so I could mount the little sherline 4-jaw
[11:14:55] <cradek> maybe you could do a similar thing for WW, but not being hard I bet it wouldn't last very long
[11:15:16] <archivist> kwallace, you know you can code the path in gcode to generate the involute, no spreadsheet needed :)
[11:15:18] <cradek> you'd have to make a very silly drawbar
[11:17:28] <kwallace> I have been studying this link, http://www.csparks.com/watchmaking/CycloidalGears/index.jxl to try to create the tool path for gears, but I don't have a handle on it yet.
[11:22:06] <archivist> I have hand ground up a cutter to be near enough for a clock date wheel, else over her we just use cutters from a british maker so rarely need the cycloidal maths
[11:23:21] <archivist> eg http://www.clock-works.clara.net/cata/wnpc.htm
[11:23:36] <jepler> hm actually posting a post takes a very long time
[11:24:00] <jepler> I have a feeling that it is taking a lot of time to send out e-mails now, such as to people who are following a post
[11:27:09] <kwallace> To me, the tooth cutters are too expensive and I really like to understand the details if I can. Crud, I need to drive Mom to another Dr. apmnt. bbl.
[11:29:10] <jepler> in fact it's been minutes
[11:29:25] <cradek> to post on the forum?
[11:29:39] <jepler> yes, I clicked "submit" before 10:58 and now it's 11:04
[11:30:07] <cradek> argh.
[11:30:44] <cradek> I suppose only the signup-related things would really need to go through gigglemail
[11:30:57] <jepler> that is not a preference
[11:31:01] <cradek> yeah
[11:31:03] <jepler> it's all or nothing, as far as I've seen
[11:32:31] <jepler> netstat shows me that an outgoing connection to gmail (over ipv6!) is in SYN_SENT state
[11:33:24] <jepler> my post did finally post
[11:44:58] <jepler> The Gmail mail server send limit is approximately 100-150 emails per day when connected to the server from a remote email client" according to this undated e-mail
[11:47:10] <jepler> so far since setting up the system, it appears 286 e-mails have successfully been sent
[11:48:21] <jepler> .. 50 in the last hour
[11:48:53] <jepler> so we may be sending enough that gmail is rate-limiting us :-/
[11:48:59] <jepler> so much for that great idea
[12:07:31] <lair82> Hello Guys, I have been on the mailing list about copying files around between Wheezy and Ubuntu, and have been talking to some people on the #debian forum, For some reason when I edit my nc files, it is changing the permissions of the file, so it can't be accessed from any other machine on the network. Any thoughts as to what may be causing this?
[12:08:59] <lair82> I have tried mousepad, kate and gedit, and they are all doing it, I tried to change the umask, but the debian guys said that is going to have no effect on fixing whatever is going on with my machine
[12:15:05] <andypugh> Is anyone else seeing the forum being very slow to post replies today? Like 10 minutes… (but if you press “Cancel” the reply is there?
[12:19:28] <jepler> andypugh: yes
[12:19:31] <jepler> I fear it's due to the e-mail change
[12:19:38] <jepler> check into the log from about 50 minutes ago
[12:19:39] <jepler> zlog:
[15:53:01] <andypugh> Ah, I see.
