Re-primed R-1012 counterbalance rib, squeezed the rivets for the R-1012 and used a “heavy duty” 1-1/4″ OD closet rod from Home Depot with a 7/8″ Husky socked bolted on one end.  Mounted a ratchet in the socket and per the plans rolled one section at a time (from cut out to cutout).  This worked well with two people.
