[00:00:55] <DaViruz> "Iceland, invaded in 1940 by the British after the neutral nation refused to enter the war on the Allies side. The invasion force, of 745 marines, met with strong protest from the Iceland government, but no resistance."
[00:00:58] <andypugh> Historically our wealth as a nation depended on world-wide trade and so we wanted a fleet capable of assuring he safety of all merchant shippping worldwide. (and genuinely protected _all_ merchant shipping)
[00:01:42] <DaViruz> i guess sweden could have been invaded for the same reason then :)
[00:02:22] <DaViruz> i'm not sure what use inviding iceland is
[00:02:49] <andypugh> I would expect that in 1940 the real aim was to be able to harbour convoy protection vessels in Icelandic ports.
[00:03:42] <andypugh> The Icelandics had to say “We are neutral, you can not use our harbours” and we said “how about if we invade you” and they said “works for us”
[00:03:57] <DaViruz> i guess iceland was more sincere about their neutrality then we were. in reality we helped whoever as long as they didn't tell anyone
[00:04:07] <DaViruz> ah i see

[00:08:54] <andypugh> Actually, it wasn’t quite like that, but it was nearly like that.
https://en.wikipedia.org/wiki/Invasion_of_Iceland
[00:09:37] <andypugh> The problem for the UK was that Denmark was under German control, and technically at that point Iceland was tied to Denmark

[00:14:40] <SpeedEvil> ^The UK is actually AIUI self-sufficient in food calories - if we stopped exporting food, and stopped feeding so much to livestock
[00:15:39] <andypugh> Indeed, with a monoculture or potatoes we would be fine. And cover the one majot food group (chips)
[00:16:55] <DaViruz> all this invasion business made me hungry
[00:17:02] <andypugh> That Wiki article is genuinely funny. It’s like a comedy invasion. But actually hugely important in world history.
[00:19:04] <CaptHindsight> Icelandic bars were closely watched throughout the war for signs of enemy infiltration

[00:24:30] <DaViruz> ncomfortable with the crowd, Consul Shepherd turned to the Icelandic police. "Would you mind ... getting the crowd to stand back a bit, so that the soldiers can get off the destroyer?" he asked. "Certainly," came the reply.[35]

[12:45:05] <Tom_itx> collet
[12:45:12] <__rob> right, thought so
[12:45:53] <archivist> morse taper collets are cheap enough
[12:46:23] <archivist> they only work on exact sizes though
[12:46:37] <__rob> there is a colet adapter for this proxxon lathe
[12:46:41] <__rob> its a micro thing
[12:46:59] <__rob> but, I dont have the collet face adapter
[12:47:07] <__rob> I do have a straight shank er20 holder
[12:47:17] <__rob> that should be ok in a 3 jaw chuck no ?
[12:47:17] <archivist> best to do everything in one setting
[12:48:08] <archivist> ER collets are not the best for random clamping bar has to be full length of collet

[16:10:00] <CaptHindsight> depending on the version of RTAI what happens will change with that parameter

[19:19:18] <cradek> yeah
[19:19:38] <cradek> to bend that sharply, the wire would have to be very fine

[20:24:07] <gregcnc> I understand it's also normal to use a brake while c axis is active
[20:25:59] <Sync_> enleth: you can position an async spindle just fine
[20:26:15] <Sync_> but yes, there are a lot of servo spindles
[20:36:05] <enleth> I've even found a guy who retrofitted a servo as the main motor in a bridgeport
[20:36:53] <gregcnc> What do you want to do?
[20:36:57] <enleth> although there is one problem with that if used for positioning: the splines have some considerable backlash
[20:37:43] <enleth> right now, just see what makes sense for a possible future upgrade, no immediate plans
[20:41:38] <gregcnc> unless you want to tap really fast what would it be used for in a mill? I'm asking because I don't know
[20:43:30] <pink_vampire> for M2 bottom tapping it's better to do it by hand? or with servo spindle?

[21:03:58] <gregcnc> I thought I saw some reasonably priced AC servos/drives for driving the spindle for machines of that size, but can't find it now

[21:06:05] <pink_vampire> for 3 springs to make a servo spindle conversion.. it's (a bit) over kill..

[21:32:29] <pink_vampire> how I can fine the SFM of material?
[21:32:36] <pink_vampire> find*
[21:37:44] <gregcnc> cutting speed depends a lot on the tool, best to look it up in the tool makers data

[21:49:56] <pink_vampire> gregcnc: I'm talking about bismuth
[21:50:19] <pink_vampire> I think it's similar to lead / copper.
