If not a hob maybe a single point cutter? The problem with doing a hob is the pitch which would require interesting gearing on most lathes.

A CNC router would be ideal here but I don't have one of those. Maybe I should build a CNC router instead. The thing I have about cutting them out on a bandsaw is the thought that the gears would end up bumpy.
