Gravity bends a crank?

[Roger/Sacramento]

It has been verified that a sheet of window glass standing vertically will eventually become thicker at the bottom than at the top. It sort of slides down as if like honey. I suppose this could happen to a vertically standing crank if left that way for a long period of time. So make sure when storing you alternate positions from time to time. Need data to know the proper timing on this theory. Has anybody on the BARN done the research ?
