In this photo, Adagio’s male mold is being constructed to laminate both hulls and the underwing as one continuous structure. We used the underwing section of the mold as a large laminating table to build all of the structural bulkheads.
That is why the right hull in the photo (the port hull mold) is unfinished at this stage. Because the cabin-back bulkhead is so large, we built the underwing mold/laminating table to extend through the space that will become the port hull mold. Once the cabin-back bulkhead was completed we could finish the port hull mold.
