Cutting a tapered thread with G76

Not the best thread I've ever cut but it's tapered and seems to work on the fitting so somewhat of a success (did it the hard way with multiple g33)

You can even run the thread through, changing the angle (and possibly the pitch)

I have a subroutine to cut tapered threads. John Thorton helped me write it a few years ago.
the sub uses G33.
I use it a lot to cut pipe threads.
See attached files for 1/8" and 1/4" pipe.

At that time I looked at the source code for G76. I think it could easily be modified to do tapered threads.
