One big problem with reground cranks is no one seems to grind the radius in the rod journals like it should be. That is a high stress area. It should have the right radius and a smooth surface. This is very important, most that I see have no radius or they grind to the radius with a sharp edge on the wheel and leave a step. That is a break waiting to happen.
