Finally got all the rivets on the right side done. Then moved on to installing the floor pan on the right side. Carefully removed all debris and vacuumed everything well before sealing it up. Floor slipped into place fairly easy and was able to align all the holes with clecos. Starting using the manually rivet puller then used my pneumatic one. The pneumatic one sprays oil all over the place though so went back to manual. Got tired of that and decided to just deal with the oil spray. Then the pneumatic one stopped working - not sure what's wrong with it. Back to manual. Took a long time to get them all pulled. 7/16: got the last side rib riveted in place. The right side of Section 29 is done. This section is taking forever. Just noticed that at some point in the past week I passed 1000 hours.
