Marked the F1032 longerons per the instructions, trimmed to length, made and smoothed the notch, and then bent them using the skin as a guide. Assembled the F1008 and F1010 bulkheads to the bottom skin and then threaded the F1047-F stringers into place, located them per the instructions, and match-dtrilled through the skin into the stringer centerlines. Repeated the process for the F1047G stringer. Added the bellcrank ribs and drilled to the F1007 bulkhead per the instructions. Added the right side F1047-C, -D, and -E stringers and then clecoed the right skin over them. Located the forward end of the stringers per the instructions and drilled and clecoed them. Next session I will continue match--drilling the stringer centerlines through the skins.
