I cut out and shaped the end ribs for the right aileron, then used my hinged 2 by 6 to clamp the aileron skin into shape. I marked the 1.5 inch spacing for the rivets, leaving un-marked the spaces for the hinges. Then I drilled and clecoed all the rivet holes outside the hinge areas. Next step will be fabricating the aileron horn brackets, positioning them and drilling and clecoing them into place.
