Dimensional Changing the crank with Nitriding would be a hell of a stunt from what I understand. Since the changes are made on a molecular levil with heated gas atoms altering the structure that would be pretty cool to for anyone to even be able measure that minute a change.....however if due to heating (the guy I talked with mentioned 1000F max things got pliable and were distorted by wacking or dropping the crank dimensionally things could change big time but not the machine work dimensions..JMHO
