Brief Description: Blend Left Top Outer Wing Skin Joint
16-2: Step 5: Blend Left Wing Top Outer Wing Skin Joint using block sander and 150 grit aluminum oxide paper. I brought the outside edge to .020 inches thickness one anvil depth of the 0 - 1 inch micrometer. The forward edge, the one over the inner skin that butts up to the .032 inch wing tank skin thickness, was worked down only a few thousands for the full length of the overlap joint. Test fit on wing showed very little proud metal at leading edge of joint next to .032 in test piece. Side joint mid lengh down the seam wal also acceptable. I probably took off less than the plans indicated but I did not wish to challenge structural integrity.
