I recently bought a nice Campy record high flange hub, and when it came to me the lock nuts were just barely threaded on. I assumed this was from the former owner checking a date code. When I went to tighten them down, I found the locknuts would only go a turn or two before jamming up.

You're probably thinking what I was thinking: someone swapped the axle and hardware for a non-Italian axle, but kept the lock nuts.

Well, I went to unthread everything to pull the axle and lo and behold the cones are genuine Campy marked 10x26. They thread just fine until they get to the ends of the axle and won't come off.

A closer look at the axle ends shows the threads are quite smashed. I would presume this is from being mashed into the dropout hundreds of times?




Anyway, is there any hope of "chasing" these threads so th lock nuts can go on?
