Tonight I match drilled the aileron skin stifferner in place (and to the bench top) just like the elevators and rudder. I then used the engraving tool to code each stiffener to match the code on the skin. That way I will install each stiffener in the correct postion, once they are primed. I then heated up the soldering iron and removed the blue plastic from the top skin rivet lines and also removed the entire plastic on the bottom side of the skins.
Aileron Skins ready for stiffeners
Rivets on top (leading) edge of the top skins need to be re-riveted
