As a one time semi-practicing machinist, I would be be very interested

That's true but many people own lathes. A nice Bridgeport vertical mill
(as Bruce Gordon used) is another level of expense mass and shop space.

I wish I had the shop space for a mill. I do have two metal lathes and
one wood lathe, the latter in semi-storage.

But if I were mitering tubes for one bike frame, I don't think building
much sophisticated tooling would be worthwhile. Something simple,
perhaps, based on using the compound rest to control angles.
