A while ago, I started buying and fixing used bikes and parts.
As a result, I have quite a large number of old individual wheels lying around, most of them with bearings that are no longer good. Since it's typically the cones that give out first (by design, if I understand correctly), one could of course replace the cones. Those do cost a bit, though. But most of all, I like repairing things whenever I can, rather than replacing them.
So here's my question: Would it be possible and sensible to machine the bearing race of the cone, rather than replacing the cone?
I assume that 0.1 or 0.2mm (up to 8 thousands of an inch) should do to get a nice surface, and that this should not be a problem for the overall geometry.
Would you say that is about correct, or am I overlooking something?
