Rudder Stiffeners, Bellcrank Housing, and Rear Upper Deck Finished

I got a manual squeezer which was able to get into the areas I needed. It kind of bent the rivets over in some cases which I don’t understand why it was doing that. I had it straight on to the rivets, but I couldn’t tell if it was bending open some or not. Either way, I got that all done and the upper deck is almost done and the battery / bellcrank housing is done. I just need to finish riveting some additional parts of the upper deck, put a few bolts in there, and then rivet all of the top skin and we are done with the empennage!
