Interesting, Dave.

Looks like you rough the entire cup with a spade drill /form tool you make yourself from tool steel. Not many machinists make their own tools any more.

I assumed that mouthpiece cups were finished with a single-point boring bar. Do you use the form tool for the finish also, or a boring bar?
