Sync_yeah my lathe can do steel00:01
Sync_well, I clamp the nut against the screw00:01
Sync_that eliminates the play at the cost of wear00:01
glowplugWouldn't that wear cause the leadscrew to be less accurate over time though?00:06
Sync_that's why you use brass for the nut00:06
Sync_because the brass will wear and not the screw00:07
glowplugYou are talking about a method like the youtube video I linked.  Where he had a spring that pushed down on the nut from the side?00:07
Sync_yes but only I have no spring00:07
Sync_I just clamp it directly00:07
glowplugDo you have a link for what the setup looks like?00:08
glowplugAlso that is an extremely good idea with the nut.  As long as the nut wears but is clamped down snuggly you wont lose accuracy.  Very nice. =)00:09
Sync_I cannot find proper pictures I'll take some tomorrow00:13
glowplugAlright cool.  I might still end up using the spring method but I would like to see how you have it setup.00:15
Sync_it's just a screw through the nut00:20
Sync_the nut is a long block00:20

B0101I wonder what effects copper electrodes have on making LEDs11:24
B0101I tried building an OLED based on Jerri's glowstick video, but this time with copper as the electrode. It didn't work11:26
Sync_possibly copper ions contaminating it11:34
B0101hmm, but wouldn't the free valence electron allow for conductivity in the blue dye? (9,10 disphenyl antracene)11:36
Sync_good question11:41
B0101hmmm.... what is the rate of Cu2O and CuO growth while being heated @ >200C for half a minute?12:49
