Last session I cut and sanded everything to get the top of the aileron bay closed out. Well, not everything; after gluing in the CW37 piece I realized that there were some additional supports I hadn’t cut. As I was running short on time, though, I had to leave them for another day.
The fun part (and it actually was kind of fun) was cutting notches in CW37 for the ends of the rib caps. After marking the location of both sides of each rib. I cut a shallow slot with he razor saw, then used an X-Acto knife to gradually fit the depth of the notch to fit. In the end I got it in and clamped, then had to leave.
