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?

I have never been able to make a nice groove in a round piece with a
dremel, it grabs and cuts an arc, and with music wire (how thick?) the
wire would be bending a bit, too.

If you have a straight shot at the end you could make a small toolholder
that fits over the end of the wire, maybe bottoms out, and has a cutter
that you advance with a screw, almost like a tubing cutter but with a
small parting tool, or a collar with a setscrew but the setscrew
advances a parting tool.

It's 1/8" diameter, and I was thinking of something along the lines of
your toolholder idea.

I would say you could sell such an item... there's a good need in the
RC industry for a reasonable way to cut a nice C-clip groove in, say,
a 5mm ground motor shaft.
