Probably not, this is caveman technology! I do like it though.

Maybe here's a pic or 2 of the application.

I would be interested in hearing more about
what you did, and how you went about doing it. I? hope some
day to be skilled enough to make a rifling machine, and it
looks like what you've done here could be helpful to
know.

Hope I can find
the pics of part of my never ending project from a few years
ago.
Needed to cut 1" pitch on a
4" diameter part 24" long. Here's the kicker,
2" root diameter. Don't remember the angle or
radius at the root but you get a sense of the process.
Single point was NG, milling was the only
option. 2 pcs. 303 SS and 2 pcs. Delrin. 1 each left hand
and right hand.
Not regular screw threads.
Feed screws for pleated filter media to glue the ribbons
on.
I love a little challenge once in
awhile.
