Same reasons as for my annealing post: I'm trying to do a nicer job of
mounting wheels on model airplanes.

Given a piece of music wire that's already bent up (because you don't
really know where the end is going to be until it's bent), how would you
put a snap ring groove in a piece of hardened music wire? Would a groove
made by a 1/32" cutoff disk in a Dremel tool have any chance of being
good enough? Can you think of any simple fixturing that would make the
process better?
