Facia Former Board Mounting Details
This photo better shows the mounting details. All of the joists and risers through this section were modified to accommodate the plywood. Each riser was cut 3/4" lower - that was straightforward. The joists had to be notched, with 3/4" removed from their top surfaces. The end result was a flush transition between the plywood and 2" joists - perfect for the insulation foam I plan to use for the scenic base.
