I have a drill press vise that has four pivoting surfaces - two facing  
two - that will accommodate tapered and odd shaped things. I'll attach  
a photo. Then it's a matter of center-punching, and using some oil  
while drilling. I've done a whole set at least a couple times if not  
more, and it isn't TOO bad a job (not that much fun, though). I think  
this style of vise is pretty readily available.
