This may be the quickest step in the build to this point. All of the flap parts, with the exception of the skins, spars, and trailing edges have been drilled, cut, and deburred as specified. The primary task in this step is to bend the spar flange of the inboard ribs to be parallel with the forward edge of the bottom skins. The inboard edge of the flaps flares out just a bit, which changes the angle of the inboard rib. The most challenging part of this step for me was figuring out the orientation of the bottom skins. The forward edge is shorter than the trailing edge, the square edge is outboard and the angled edge is inboard. Once I had that figured out, I cleco'd the inboard ribs to the angled edge of the skin and adjusted the spar flange angle.

The final task of this step was to cleco the flap skeleton together. The drawings in the plans are very clearly marked to show the orientation and location of each part. I marked each of the nose ribs (L-1 through L-8 and R-1 through R-8) from the inboard end of the spar to the outboard end. I did the same for the main ribs to help me maintain this orientation throughout the remainder of the build.
