[Al Skierkiewicz]

Bill et al,
The bump of a flush mounted bearing is not at issue and should be viewed in terms of the "minor protrusion no greater than 1/4"" that a bolt head or weld produces. I do not want teams to think that pillow blocks or other mounted bearings mounted on the outside of the frame will be looked at in the same light. "Minor" is the operative word here.
These are a sampling of what I am thinking might need to be included in the Frame Perimeter determination, depending on use and orientation.
