I dimpled all the holes in the tank and joint strip for #8 screws, installed the many nut plates on the joint strip then installed the tank. The tank was installed in a temporary fashion with just enough screws and bolts for verifying the fit. (The tank has to be removed to fit the wing to the fuselage.)
I also made a lot of progress starting the cradle that will hold the wing for the rest of its assembly and storage.
