My 19 year old daughter Sophia helped me rivet the flush rivets for the nutplates for the root z-bracket. We had to drill out one, but that went well. It's the first time she's bucked rivets, so she was proud she "built an airplane."
BTW, they should have instructed the builder to install those nut plates BEFORE riveting on the main wing ribs. They would have been a lot easier to do, and would not have interfered with installing the ribs.
