Final sized and dimpled tip skin for wingtips. I have decided to go with one of the standard vans solution for nutplates out on the tips rather than the hinge solution that has become pretty popular. The other possibility is to just pop rivet them on but since I'm going to have lights and VOR antenna out there, it seems like making them somewhat removable is the way to go. Cleaned up a few other little tasks: Torqued down the heim joints in the flaps, including blue lock-tite. Took the flaps and ailerons to the hangar to join the rest of the flight control surfaces. Worked on all the nut plate locations on the wing root. Dimpled or countersunk as required and added nut plates. Ran out of time and have just a couple left on one wing, plus the ones on the fwd tank attach brackets. FYI- the upper wing root fairing is dimpled and nests in countersinks through a stackup of materials. Per print, they knife edges the upper skin and go about 1/2 way through the wing walk doubler. It's normally frowned upon to knife edge your countersinks, but in this case it's through a thick stackup and the structural elements are sound.
