Riveted the Shear Clips (F-1284) to the J-Stiffeners (F1283 A & B) and then riveted the J-Stiffeners to the Bottom Skins (F-1282). To attach the Frames (F-1208, F-1209 to the Bottom Skins you have to turn them upside down and need tall saw horses to prevent the the largest frame from hitting the floor. I put a 30 inch saw horses on top of a 10 inch box and used the grinder stand to support the other end of the skins. I then clecoed the 3 Frames . Had to flute the Frames to align some of the holes. The fit was good, so far.
