Showing two main tanks in work. Notice bead rolling in bottom skins!

Pic showing bead rolling inside each baffle area.

This picture provides an illusion. First - the picture shows that each hole is clecoed during the fitting phase. It also looks like I used tape to mark the areas that I am drilling. Actually, if you look to the left you will see the piece of clear plastic thatis installed on top of the tank but below the clecos.

These are casting forms. Each was made oversize to allow for shrinkage. The two on left are for the forward wing spar, the top middle on is for the wing flap gearbox, the long flat one is the flap handle arm, the next one is the rudder cable casting, and the two bottom ones are the rudder antenna post holder and bomb rack fitting.
