beware, the nut and washer trick only works on really old cheap cups.
Anything decent/modern have hollow walls, and the method will crush the races rendering them useless.
Also the bolt's got to be pretty special, otherwise it'll just shear. Be careful of trashing frame too, its worth soaking it in plusgas (or other decent fluid) for a few days first.
