fedex broke a crank I shipped. They dropped it on the flange end and must have hit at a 45 or something as there was a huge 50 degree chunk of flange rattling in the crushed box. I even put a 3" styrofoam block at each end.
When a crank warps from being stored on it side or improperly (not on its end?) they say to mount it up, torque it and walk away for a week. Even metal is somewhat fluid over time. They rotate propeller shafts on ships when they are stored every now and then.
