Placed cargo straps around forward top skin. Placed 1"x1" boards on each side of skin to press skin against bulkheads more tightly. I placed a long board across the F-606 and F-607 bulkheads and climbed into the fuselage. I laid on the board and back-drilled the F-607 to the forward skin, through the aft top skin, from the center down the right side. Back-drilled through the right longeron and the forward skin.
