The fuselage is of "monocoque" or "stressed skin" design, meaning the rigidity is obtained by assembling the skins onto bulkheads and stringers. The first task is to fabricate all the bulkheads, from the firewall in the front to the last one in the tail. I needed a good part of the afternoon to locate all the bits and pices scattered around the workshop. On the first picture all the bulkheads, except the firewall which is on the second one.
