I turn the barrel in the lathe chuck and use a Jacob's chuck in my tailstock to feed the 'chamfering cutter' in. I eyeball it until the groove is cut to the bottom.

I've seen multi-angle crowns, rebated crowns, and odd angle crowns but really, is all that necessary??? I'm a simple person, my tools are simple, my work is as simple as I can make it.
