re: as simple as 1,2,3... ENCODER/JOG

Hi to the list,

In thinking about the encoder Joystick interface and Bill's question
about synchronizing lathe spindle and carriage move, Bill Darby just
gave me an idea:

What if I setup my rotary table and a tail stock on the Sherline mill,
and use a 60deg. conical point (or something else?), by driving the
rotary table and the 'X' axis, I should be able to cut threads on the
mill! Although other then the obvious code to simulate a "back gear
ratio" between rotary table and 'X' axis, I haven't sat down to figure
out how to do it in CAD/CAM.

Going one step (ha!) further, one should be able to cut an ACME screw?
The nuts are going to be a little harder to crack, er, machine! (oops,
did it again) ;>)
