Today I drilled the 1/8th holes common between the centre bottom skins, the F-822 fwd floor panel, and the centre section bulkheads. I drilled the aft lower skin to the bulkheads as well as the Baggage rib assembly. I also drilled the four 3/32nd holes to full size in the same panels. I then clecoed the three bulkhead tops to the F-807,808,809 bulkheads and clecoed into place the top deck skin.
