Mark,

As you say, a good resource for those impossible to find parts.

One thing that I question and the person didn't address in his eBay listing description was what about bearings that are not through hardened.

Many lower quality and some top quality bicycle cups and cones are not through hardened.

You can do the best grind job in the world but once you get under the 58-60+ RC layer you're into softer metal.

The deeper you grind the softer it gets even in many through hardened parts.

Also the last time I read his listing he seemed to indicate that he could regrind anything... I have some BB spindles with 1/4" chunks missing... ;-)

Keep us updated how your regrinds last.
