i really think Bulkheads are the structure of any fuselage other than glass types. when i cut these i will only leave approx 1/4 inch of wood material to all 4 edges and use 2 x 1/16 inch ply laminated to form cross grains, this method is very strong and very very light. the same goes for fuselage sides where i use the good old method of balsa doublers set at 45 degrees and lightly laminated to the mains.
