Clecoed the bottom skin to the aft and forward bagage door ribs on each end since the ends are flush with the skin. Used the prepunched holes in the inner skin to locate and drill the holes for the aft and forward baggage door skin, cleco as progress is made. Eventually ended up with a completely drill structure for the inner door skin and forward/aft ribs.
Now, it was possible to locate the top skin since the outboard rib could be used to locate the outboard and inboard holes of the top skin. Then, used the pre-punched holed of the outside skin to locate the holes for the forward and aft baggage door ribs, cleco as progress is made.
At the end, al holes drilled and clecoed.
Inner Skin drilled and clecoed to forward and aft ribs
Top Skin match drilled to farward and aft ribs, and cleco underway
