Deburred and dimpled holes in F972 bottom skin and clecoed onto fuselage. Countersunk F972B's and clecoed into place. Deburred the F714 aft deck and clecoed into place. Riveted F714. Trimmed a F757 gusset and tried to place. Realized I hadn't cut the slot into the F721B so I over-trimmed the gusset way too much. Fabricated a new F757 with some left over sheet metal of the appropriate thickness. Cut slots into F721B's and deburred. Clecoed F721B's in place and began trimiing the F757's to fit. Drilled the F757's after clecoing in place. Measured and drill aft three holes into F757's as well as the hles throught the 721B's through the 718 to the 757's. Removed all pieces and deburred and dimpled. Countersunk the holes in the top of the 718's where the 721B's are located. Riveted the side skin to the 718's where the side rails go except for the few at the forward end where the F775 top skin goes on. Clecoed in 721B's and 757's. Quit for the day. A good day overall.
