I cut out the parts this afternoon, and will assemble and prime it tomorrow.  I had bought 7x9s for the garage when we built the house, but when now building the 12×12 equipment shed, decided to make the matching 7×6 rollup door myself.  Core is 5/4 pine, skins are 11/32 exterior siding plywood, face trim is 3/4 western red cedar, lites are true divided.  Overall it is about 2-3/8″ thick, and has shiplap joints at the horizontal junctions.  Each panel is 72 wide by 27-1/2″ tall.  I will do a photo of the shed with garage door installed when all is done and painted.  Wish it would stop snowing!
