You mean across the floor? I think ours are bolted down. I was referring to the speed of the axis movement and tool changes.
I will! I've seen the taps that have a grove down one side, but not on the very small ones (4-40 to 0-80). Do you have a brand name?
Should be. But I just look. I'm in the lathe dept. (I work with two citizen L25s and one M20)
Yeah.
So, in he end, were these. LOL
OSG is one.
Lathe's are dangerous. I stay away from anything that has the work piece flying around as a normal part of the process.
I've used Alumicut for threading operations. I had some gummy extruded rod I needed threaded on the ends. Regular aluminum threading compounds just left a ragged mess resembling a corncob. Alumicut left nice shiney threads. Was good stuff. Just googled it, looks like it's still available, might not have the same composition. Was a light oily liquid, not like Tap-Magic was.

I use alum-tap, specifically formulated for tapping in aluminum. it seems to work LOTS better than oils. it is a clear, oily fluid. I hope it is still available. I used to use a tapping head, but now have rigid tapping on the mill. I tap small holes up to 1200 RPM.
