Finished riveting on the wire cradles to the rear spar. Flipped right wing skeleton over and clecoed on the bottom skin. The wing was turned back over to start cutting and fitting L-angle stiffeners. The angles were cut, then checked for fit. Once they fit, the first two holes for the rivets were marked through the holes in the skin and drilled, then the angles were clecoed on for drilling the remainder of the holes.
