Riveted the rear spar together, got on a roll and riveted the ribs on the rear spar too. Wondered briefly why I needed blind rivets on the middle rib, when I had such good access, but just briefly. Read the next step and saw that I was supposed to rivet the ribs onto the FORWARD spar. So, out came the drill and I drilled out the rivets, and then followed directions and riveted the ribs onto the forward spar. Messed up one rivet, so my rivet drilling experience will come in handy tomorrow when I drill out that one. Then I'll be ready to rivet the skin on.
