In article , John Flanagan says...

If you had a lot of them to do, I would consider making a profiled
plain milling cutter (to match the smaller diameter) and then simply
do the entire piece with one pass on a horizontal.

Good idea Jim. But I will probably be doing only 4-8 at a time maybe
once or twice a month.

You could start with a simple 90 degree V-cutter, and then form
grind the tip of the V out, as a radius.

Plain milling cutters are cheap.
