So I've got a nice hybrid bike that I picked up secondhand, was doing some maintenance on it to get it up and running and thought I'd replace the bearings in the rear axle. In doing this, I've found a small pit in one of the cone nuts.
I don't have a picture, but this is the type of thing (In reality, mine's not as bad as this, it's less long and less deep):
Just thinking, would it be a really bad (or silly) idea to try to file the whole nut, so that the surface is smooth. I appreciate that this would be quite a lot of work to get right.
Cone nuts seem to vary so much and finding an exact replacement could be tricky, so thought I'd explore this idea...
Look forward to hearing your thoughts!
