Nothin' to it, eh?

My lathe--even though it is Chinese--is sophisticated (?) enough that I can cut all
the common metric threads just by changing dials on the lathe. No gear changes,
thank God...

I’m fortunate enough to have all quick change gears for metric and inch threads on my daily lathe at work. My home lathe, not so much. Too old of a south bend for that.

Ran a Meuser for a while, had around 150 or more different threads on 4 or 5 charts. Had 8 different ways to cut a 1"x8tpi thread.
