Start of right and last flap today. I started by smoothing all parts. This took about 2.5 hours. I then clecoed the parts together and match drilled everything together including the 2 small FL708 spacers that fit between bottom skin and end ribs (Image #3 below). Instead of making this part exactly to dimension on drawing, I cut the part longer than required at first to simplify positioning the part between bottom skin and rib to match drill. After the parts were matched drilled, I cut the part to the dimension given in the drawing maintaining the edge distance….. much easier this way.
