I did the sockets with a form tool on the lathe. But, for the balls, I made an internally threaded collar and slit it along the axis so it would squeeze the threads when clamped. I mounted a carbide triangular insert on a QC lathe holder and clamped it in the vise. I set a few offsets and turned it loose with a simple program to step inward with am arc move. It made excellent balls, although it obviously wasn't as rigid as a solid lathe. > But my question is EMC2 settings and how I can use EMC2 in ways that > are more lathe specific.

Really the only thing is the tool offsets, and EMC2 now has lathe offsets. This only matters when you are changing tools in one setup.
