This is a summary of work done since last weekend.
I re-worked the trim tab closures, and then dimpled the trim tabs and control horns for rivets. The Trim Tab spars were also dimpled and countersunk for rivets.
I managed to remove most of the wrinkles in the trim tab skins - the result is not perfect, but I think it is acceptable. The worst of the endges is shown in the pictures. - I may work this a bit more to try to smooth it out, but I am leary of dong too much and work hardening the metal.
wrinkling of the skin near the closure tabs. Ths is the worst edge.
