FUSELAGE BULKHEADS
.....
In this section, you will construct the following bulkheads:
FS120, FS94, Seatback Bulkhead, and aft canopy bulkhead. All bulkheads
are made from the 3/B" thick white foam. You will find full size
template outlines on the large Appendix Sheets 1 and 2. On this sheet,
you will find sketches showing the foam layouts. Where two full size
template outlines are overlaid with one another, work your way in
toward the middle by making the outside template bulkhead first, then
trimming the template down so that the inside bulkhead can be made.
(e.g. make FS94 bulkhead first, then make the FS120 bulkhead).
