Next came planking the bottom of the fuselage. I glued in a small number of trapezoid bulkheads, then ran three sheets of 1/8” planking. This is the one bit of structural design that survived pretty much intact from the original Giles, except for the lightening holes, and lack of pipe tunnel. I used a sharpened 3/8” brass tube to make holes at the corners of the lightening holes, then I cut between them. As I often do, in the middle of building something and a better way occurs to me. Rather than use solid planking, Run ¼” wide strips at the corners, then cap strip the bulkeads. In the next version this will require 3 additional bulkheads, but the reduction in waste material, makes it worth while, especially since it might also save some time. You can see where I added a “fake” bulkhead about midway through the aft section of planking.
