I finally got a chance to get down to the hangar to rivet in a fuel tank. Everything went smoothly. I had to flip the wing over on my own, but since the table were carpeted I could slide them to one end, lift it up and rotate it over the leading edge. Afterwards, I was wondering what would have happened if I guessed wrong and the wing got away from me. Next time I will get help! And, I need to do that anyway because I can't get the wing off the tables and the other wing on the tables on my own. As they say, that's just too big a lift!
