Fabricated, drilled, and primed shims for upper and lower control horns from 0.025 aluminum stock. Used 0.025 inch for upper control horn and 0.050 inch for lower control horn. Reference notes on 10/18/10. Match drilled left and right aft hinges to flanges of right main skin (page 09-08, steps, 1 through 3). Shot primer along rivet lines on inner surfaces of both main skins. Clecoed right skin to spar box assembly with all holes lining up with little trouble. Riveted right main skin on upper and lower surfaces except for aft skin holes on outer trailing edge. Clecoed left side skin to spar box assemblies with all holes lining up with little trouble (page 09-08, steps 4 and 5). Still need to complete step 5 by riveting left main skin to spar box assemby.
