I riveted in the right middle nose rib to the top skin without too much muss or fuss. Vicki helped me by shooting the forward most rivets on both ribs Next, I clecoed in the rear middle rib and the tip rib to hold down the skin to rivet in the bottom of the middle nose rib. I can see the method to the plans’ madness. I won’t rivet until I get the “oops” rivet from Vans (I ordered it today).
