Riveted reinforcement plates to spar. Clecoed top rib to spar. Primed nutplates. (Placed bottom three rivets on lowest reinforcement plate “shop-head out” to amuse future Oshkosh judges. In case I am one day deluded into thinking I have a “perfect” airplane, these rivets will keep me humble. That's my story, and I'm sticking to it. To reinforce this notion further, I had to drill out and replace one rivet.)
