I'm overhauling the hub on my project bike and noticed some pitting on the cones. No problem I think, I head down to the bike store with one of the cones to get a couple of new ones. But no, It seems Shimano has used something like 5million different cones throughout the years.

I should be able to get some replacements, but one of the mechanics mentioned something about polishing the pitts out by mounting the cones to a drill press and using some steel wool on them. Has anyone done this or have details on this procedure?
