Brian, thanks for elaborating on this.  The "ridge" is exactly what I have
and want to remove.  I don't have the little center bump, but I've seen it
on other capstans.

My MSC Industrial Supply Co. catalog (800-645-7270) has several different
models of 3M (Scotch- Brite) deburring wheels.  I'm tending toward the
Scotch-Brite High Strength Disc designed for light deburring work.  What is
the wheel you're presently using?

Thanks for the expanded answer, have a good weekend.
