Dan came over again tonight to do some more work on the bottom skins. We got the left wing almost completely riveted. Unfortunately I ran into a snag while trying to rivet the aft flange of the second most inboard rib to the rear spar. I've already attached the flap brace, so I need to make a custom bucking bar to be able to buck two of the rivets. Dan headed home and I spent another hour riveting that rib to the top and bottom skins.

The wing looked so good I just had to set the tank in place to get the full picture. I've still gotta prime the outside of the tank ribs and baffle before I screw it on. Brent's supposed to come over tomorrow to work on the other wing skins, so hopefully we'll make some good progress.
