Re: Gravity bends a crank?
Glass don't move, it stays the shape it was made. The belief was based on the thick bottom of a window. This was just the way it was put in in the first place.
And if JWL has stated that flathead cranks stored anyway for unknown time, show no evidence of "bending" in storage, when put on a crank grinder, then the question has been answered.
They don't bend.
