Just posted a few photos of the folding wing joint in my album. Haven't seen too many other close-ups on this site. Hope it helps.

Les, in Albuquerque

That looks really good Les... nice work!

that all looks really good. The parts all look very professional! Out of curiosity, did you fabricate (what looks like to me) that u-joint type connection near the rear spar? That would seem difficult to precisely fabricate.

Don't know if you know, but the U-joint tube slides in and out to accomodate closing the gap between outer and center wing before installing the pin at the rear spar. The tube is hollow, but I pressed a solid plug in one end to machine the slot. The other part of the U-joint is milled with a slot also. Not too difficult. The U-joint does need to allow enough freedom on the wing to line up holes for the pin. Until you get it all worked out it takes a lot of on and off cycles with the wing. Good to have a helper for that.

If you need more photos of the folding gizmo , I have several in my photo section to graze upon . Les is right, a helper (my wife) sure helps a lot to get the wing into the flight position . When I am ready to bring it home I can fold the wings myself while on the trailer and then head home .
