I resumed work on the right flap by closing up the nose by flush riveting the line of rivets on the bottom side. As before, I used a digital level to monitor the twist of the two hinge brackets while riveting with the bucking bar held inside. Once about a dozen rivets were in, the twist seems to be stable and doesn't vary as the remaining rivets went in. I think the final twist of this flap will be about 0.2 degrees, the same as the left one. With those solid rivets in, I finished up by installing the pulled rivets along the nose ribs.
I prepared the two aluminum extrusion wedge pieces by adhering the 3M VHB tape to both sides, and then inserting them between the two skins and clecoing them in place. As before, I placed the flap upside down on my kitchen countertop and weighed it down with some cement trim and dumbbell weights.
What's next? After the adhesive has cured overnight, I can do the double-flush riveting on that trailing edge. Then I can finish up by installing the remaining pulled rivets for the ribs
