Just had an hour today to spend in the shop. I was able to cut, sand, and locate the 8 skin stiffeners for the bottom of the left aileron. I then drilled and clecoed them to the skin, and to the work table. Then I drilled the skeleton to the lower skin. Be sure the stiffeners are not going to interfere with the final bend on the trailing edge, and that they will not contact the spar. I probably left .040" or so between the spar and front of the stiffeners.
