(1) Connor dimpled the right wing walk doubler using the C-frame, while I helped by aligning the dimple die on the holes, and he hammered. (2) Clecoed the top skins and doubler to the wing skeleton and verified wing twist w/n 1/16". (3) Clecoed right fuel tank stiffeners to skin and match drilled. (4) Clecoed baffle/rib assembly to skin and countersunk skin to baffle holes. Also drilled skin to spar screw holes to #19.
