The top rear deck core is a bit different than some. There is a flat area atop the deck that will later be capped with a 3/8" balsa sheet. This cap will provide lots of rigidity and allow us to sand a sharp radius to achieve the designed intent for this section of the fuse.

The sheeting can be laid out and tape hinged along the top edge of the flat. Apply polyurethane glue to each skin. This assembly can then be inserted (wedged) back into the shuck and allowed to dry with weight or vacuum.

Once again, sand all over-hanging edges flush to the core.
