I continued work on the right hand wing tip. I positioned it properly then drilled and clecoed it in place. Then I marked the trailing edge portion that lies next to the aileron and marked it with a Sharpie to give a 1/4" gap as per the plans. I removed the tip and cut away to my mark and then laid out the rivet line, top and bottom. I then drilled, countersunk and set the flush rivets completing the installation of the aft rib.
