Brief Description: Riveting the rib halves to the skins
I noticed that the rib halves are opposite (top and bottom), from right to left. When I clecoed the rib halves together, I labled all the larger pieces to go on the bottom. I assumed that I final drilled the right elevator with the ribs backwards. I was so sure that I called Van's to see if it was OK. I realized that I really did it right when I assembled the whole elevator. I had already riveted two pieces on. I was glad that I really did it proper and I removed the two pieces to do it right.
