This is a fun thread to read. "How many engineers does it take to ..."?? I say that with many smiley-face emoticons.

FWIW, the simple taper pin that my friend made works 10 times out of 10 with my -29. It's just a delrin pin with a solid handle at 90 degrees to the major axis of the pin. If the wing bushing are misaligned by a few mm, the pin pulls the wings together. If they are misaligned by more than that, it's time to make sure a) the flap handle was in -2 or so and b) the stick was more or less neutral and c) the divebrake handle was at the forward 1/4 or so of travel.
