Work on LW aileron: Drilled all skin holes to 3/32"with #40 bit and dimpled new skin which i ordered 2 weeks ago that i had made a drilling mistake. Then put all the parts togather as i had before, then back riveted on stiffeners using my large 1/2" x 30" x 24" steel plate on my bench. taping all the rivets in and using the same routine as the other aileron.
