Given the concern about the first broken belt removing the remaining one, I've often wondered why no one has suggested a sheet metal guard that separates the 2 belts?  A flat sheet of .040 aluminum mounted to some brackets that were outside the perimeter of the belts with clearance holes for the pulleys would shield the belts from each other... there must be at least .250 or more between the belts.  Has anyone ever tried anything like this?
