00:01 <Sync_> yeah my lathe can do steel

00:01 <Sync_> well, I clamp the nut against the screw

00:01 <Sync_> that eliminates the play at the cost of wear

00:06 <glowplug> Wouldn't that wear cause the leadscrew to be less accurate over time though?

00:06 <Sync_> that's why you use brass for the nut

00:07 <Sync_> because the brass will wear and not the screw

00:07 <glowplug> You 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 spring

00:07 <Sync_> I just clamp it directly

00:08 <glowplug> Do you have a link for what the setup looks like?

00:09 <glowplug> Also 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. =)

00:13 <Sync_> I cannot find proper pictures I'll take some tomorrow

00:15 <glowplug> Alright cool. I might still end up using the spring method but I would like to see how you have it setup.

00:20 <Sync_> it's just a screw through the nut

00:20 <Sync_> the nut is a long block

03:04 <glowplug> 8)

11:24 <B0101> I wonder what effects copper electrodes have on making LEDs

11:26 <B0101> I tried building an OLED based on Jerri's glowstick video, but this time with copper as the electrode. It didn't work

11:34 <Sync_> possibly copper ions contaminating it

11:36 <B0101> hmm, but wouldn't the free valence electron allow for conductivity in the blue dye? (9,10 disphenyl antracene)

11:41 <Sync_> hmm

11:41 <Sync_> good question

12:49 <B0101> hmmm.... what is the rate of Cu2O and CuO growth while being heated @ >200C for half a minute?
