F11-01 Fuselage Box Assembly.
I clecoed the side panels to the Aft Fuselage Assembly using the pre drilled holes in both.
I made the 5 degree bend in the lower skin. I place the skin in location on the assembly. I clamped the upper and lower cross ties to help hold the box shape. I up drilled the holes in the lower skin where it attachs to the aft fuselage. I clecoed the skin in place as I drilled. I positioned the side panels so that the lower skin was properly located. I then drilled and celcoed the pilot holes that go through the lower skin and the logerons of the side panels. I used the pre drilled holes in the lower skin for locations.
