I have taken apart the rear wheel assembly from a 1972 and found the threads on the axle are deformed.
I searched the forum posts and read that failure on the axle is typically a break at the end of the threaded portion.
I wouldn't run this axle on a road bike any more but has anyone tried to clean up the threads using a 9/16-20 die? I would guess that the original threads are rolled rather than cut to lessen the stress at the end of the threads.
