Hi Gang:

Since I received a thread cutting lathe (Smithy Granite) I have tapped thousands of hole, but only set the lathe up once for threading. And that was to guide a tap through an intermittent hole.

Tapping is one of the fastest way to add a thread to a part. Thread milling might have the possibility of being more accurate, but that depends on your CNC machine.

For external threads I keep a stock of threaded rod on hand. So to approach the tailstock screw I would tap the end of some M8x1 LH for the M5 RH and Loctite it in place, or cross pin it.

Is there a way to cut LH threads on the Unimat? Did they ever make LH masters?

Carl.
