In the morning session I made final preparations for riveting the inboard rib by ensuring all surfaces were clean and wiping everything down well with MEK. Used the squeezer to set most of the rivets, but I had to shoot a couple of rivets near the tank vent ell with gun and tungsten bucking bar as I could not get the squeezer on them properly. Used cutoff toothpick to put sealant in dimple. Picked up rivets that were washed in MEK with tweezers to insert in the dimple. Wiped off excess sealant and squeezed the rivet. Repeated in a pattern from nose to tail, setting a rivet, skipping one, and setting another rivet. Went back and repeated process until all rivets were done. Used some leftover sealant to dab on shop heads.
In the afternoon I spent some more time cleaning up the outboard rib in preparation for riveting.
