There are a total of 4 cover support ribs. Time to do the outside ribs. These have a 704M stiffener that gets riveted on the spar. Then the 782B's get screwed on the opposite side.
I deviated from the plans a bit here. The 704M stiffener is riveted onto the spar with 3 rivets. The plans say to use flush rivetes for all 3. Well, only the center one of these rivets will be under the 782B that fits on the opposite side of the spar. So why do we need flush rivets for all three? I used an opps rivet for the center rivet (first deviation) and normal 470-5 rivets for the outside rivets (second deviation).
The center flush "opps" rivet was bucked and the two outside 470 rivets were set with the C-Frame. I'll use the C-Frame when ever I can.
