I'm hoping to get a little advise. I'm looking to build a wheelset for an old frame and ended up winning an Ebay auction for a set of Shimano 600 hubs that were described as "spin smooth".

The rear hub is beautiful and spins silky smooth. The front hub is a little rough. On closer inspection, I found one of the cups to be slightly pitted.

So I'm trying to figure out what to do. I did some research on if the cups can be fixed and found a comment somewhere that using a metal polishing compound like Simichrome (http://www.amazon.com/Simichrome-Pol.../dp/B000BGOC0W) can fix the cup if it isn't to bad. You remove the bearings and grease, fill the cup with the polishing compound, reassemble with the bearings and run it until the pits are smoothed out. The bearings get tossed and everything is cleaned. New grease and bearings go in.

I'm curious if anyone has heard of this or tried it. I would say the hub is usable but I certainly would not start a new wheel build with it.

If there is not viable way to rehab the front, then I'll have to take issue with the seller within 14-days. This hub does not "spin smooth". Has anyone heard of the polishing compound trick?

Thanks!
