Drilled, deburred and dimpled the seat pan ribs for nutplates. Installed all the #8 nutplates and the one legged nutplates I had. Need 11 more one legged ones to finish. Used the pneumatic squeezer for the ones closest to the fuse sides and tried to use it for all the others. Had limited success due to access so went back to using the manual squeezer which worked much better. At least I didn't have to drill out any rivets. Not sure it was worth the time and effort versus just reinstalling pulled rivets, but it's almost done now.
