Finished riveting the baggage floor ribs to F-706 bulkhead. The angle that gets riveted on the aft side of the F-728 A Bellcrank Channel was still just clecoed on, and by removing it, I was able to get a straight rivet set on the the aft side of all those ribs except the two center ones, which I had to shoot with the gun on the front. Any time I'm able to avoid using a double offset or other weirdly shaped set, I'm all for it, so I was glad that I hadn't set those rivets yet. Per the suggestion in the instructions, I started riveting around the F-704 bulkheads and worked forward & aft on both sides. I was able to reach about 1/2 way back on the F-715 ribs trough the aileron pushrod hole, and likewise got almost all the rivets in the vertical rows through the F-704, with the exception of 1 rivet where the flange of the armrest is in the way of getting my tungsten bucking bar on it. When I get some help, I'll get on the inside where I can see what I'm doing and buck that one with a steel bar I have that will fit in there. Also finished all the #4 rivets common to the upper edge of the gear web. they were -7s (I think?) and took quite a bit of grunt to set but came out okay. If you look close at the pix below, you might notice that there are 3 rivets not set in the F-715 rib that I would have been able to reach. Thats because I already installed nut plates on those ribs, which are in the way of my solo blind bucking endeavors, so the next time I have some help in the shop I'll get those as well Will continue with the ones that I can reach solo next time, or branch out to some harder to reach ones if Kriya has some free time to shoot while I buck this weekend.
