Re:Re: I'm impressed. Anyone want to write the G-Code for this?

Huh? Bowling alleys???

Use an end mill with a curved profile, less than 10 lines of code.
(housekeeping, plus 5 circular pocketing cycles) Or, a few more
lines of code and develop the curved inner wall with a conventional
center cutting end mill.

Or a lathe with boring bar only, still about 10 lines of code.

I vote for the lathe method.
