Priming Done And Started Right Elevator Spar

I first primed all internal parts for the right elevator. On the top and bottom right skins I primed only along the rivet lines. Finally, after many hours of prep work over the past month, I started riveting structure together. Per plans I started with the tip ribs, got the reinforcement plates and nut plates attached to the main spar before getting the tip ribs attached. As usual with an initial fragile and flimsy structure much time is wasted figuring how to secure it for riveting without damaging it. I got careless on one AN470 rivet and ended up with a huge smiley on the factory head from a misplaced rivet set. I wasted an hour getting it removed due to its awkward location, fortunately without incident. Its replacement went in without a problem.
