Started putting together the fuselage starting with the center section bulkhead. Started off by countersinking and placing a few nutplates and a retainer block. The fun then began with match drilling 73+ holes into the center section assembly. Per plans I clecoed the bottom skin to get the alignment of the center section aft bulkhead and then clamps were placed to hold parts together. It took over an hour to then get all the holes drilled. A few of the holes were countersunk as per plans. The skin attach flanges and stiffeners were then cut apart and deburred.
Time: 2.5 hrs.
