It would be easy on a lathe with a spindle mounted cutter (just use ball end mill), but what about on a lathe with a standard low tech stationary cutter?
Trying to figure out an economic way to make these things - the retail price for a set is $625.
thanks in advance!
======================= I don't mean to belabor the obvious, but as this is alt.machines.cnc, do you have a cnc lathe?
If so, an old technique may help. If you lathe has enough swing, rig a faceplate. It will be an interrupted cut so HSS may better than carbide, but G2/G3 and lots of patience may be a solution.
If a strictly manual lathe you can use the method described in one of Lautard's "Machinists Bedside Readers" to generate a radius using a series of plunge cuts. see
What equipment do you have available and what are the sizes of the dies?

The dies are about 6" in diameter.
CNC vertical mill, manual lathe.
I just figured out that I could put the die on a shellmill holder (in the vertical mill spindle), put the cutting tool in the vise and do a Z axis interpolation on the mill.
Thanks for your suggestions!
