Here are a couple of pictures that show how well the back fit after I glued the drawing to a double thickness of poster board. A few holes, the interlock, and the H Size control cut outs were moved about 1/16. Then the overall outside lines were moved in 1/16. Then a final drawing was made. This will be printed off in reverse and glued to the inside of the Masonite. This way there won't be any damage to the outside or visible side of the back.
