Final drilled holes in the AST Ribs and riveted top skin to ribs. Riveted the inboard ribs to the Control Horns. This is an easier way to do it. Separated the hinge halves prior to using the drill guide to drill attachment holes. DON'T DRILL HOLES IN OTHER HALF AT THIS TIME, as I did. the are done later using the other side of the drill guide. The holes don't match (see picture). Made a brake for the trailing edge radius, so the skins will not bulge out. just tweeked the radius a little.
