Drilled the R elevator skin #40, clecoed, updrilled #31, re-clecoed. Flipped the elevator over and used a few blocks and ratchet straps to contour the skin to rib structure so the skin was tight to the ribs and spars. Aligned the skin, drilled #40 and clecoed as I went untill all of the ribs and spars were clecoed. The skin is nice and tight to the structure. Just have the hinge to drill, and then it gets riveted.
