Completed Sections 7-10, 7-11, and 7-12 Steps 1-2. After removing the trailing edge clecos from the aluminum angle, it was a bit difficult to separate the trailing edge, due to adherent JB Weld that oozed out of the rivet holes. I was able to separate using a sharp blade but there is some scratching of surface on one side of trailing edge. This won't matter ultimately as the skin will be scuffed extensively for painting. It's more of an annoyance than anything else.
Quite a lot of riveting of parts, including the final part which is riveting the trailing edge. I used the standard "double flush rivet" technique as taught at Synergy. This worked well. I did about 1/2 of the rivets on one side and noticed a very slight bow in the trailing edge. Turned it over and did the remaining rivets from the other side which removed most of the bow. After completion, measuring along the edge using a straight edge (aluminum angle), the total deviation end-to-end is about 1/10 of an inch. Very pleased with this result!.
