Brief Description: Ribs - Assembled Left wing frame
I riveted the center ribs onto the main spar and rear spar of the left wing. I decided to do them one at a time rather than cleco the whole thing together, so that I'd have plenty of space, especially among the first 4 inboard ribs. Rivet gun set to 45 pounds worked fine on 1/8th inch rivets. I decreased pressure a little on the far outboard ribs where rivets are a little shorter. I clamped the spar down to my work bench so I could put a lot of pressure on the gun and bucking bar without having to balance forces. Worked great.
