iBob, the way that worked best for me was to get the wings skins all riveted up, leaving the last few holes on the leading edge simply clecoed together. Next I strapped the wing down so that it can't move when is came time for a friendly shove with the wingtip. Next I eased the big, rounded, leading edge of the wingtip into place. With some wiggling, I then eased the trailing edge into place while applying pressure to keep the leading edge as tightly forward as I could. The clecoed trailing edge wouldn't allow the tip to drift aft, keeping the leading edge fairly rounded around the wingtip. Once I was satisfied that the tip was as far into the wing as I wanted (basically as far in as possible to give the rivets the most to grab, right to the edge of the "flat" area before the slope started), I then drilled one of the holes nearest the trailing edge one handed and snuck a clecoe into hole. Once that clecoe was in place, everything held nicely allowing me to methodically drill and clecoe each hole as I went, giving me a fairly flat and wrinkle free install of the edge. I started with the center of the leading edge, then alternately worked around the wing on both sides toward the trailing edge. I DO NOT recommend my first effort.... I placed the wing tip, drilled and clecoed it into position, then wrapped the leading edge around the wingtip much like the wing was done. Seemed like a good idea, but the straps caused dents that took much elbow grease to work out, I still have a slight depression in one place. So.... the second wing is better than the first! Oh well, my next airplane will be perfect! ;-)
