I have the wing portion done now. Despite my wife's protests, I decided the kitchen granite slab was the best, long, flat surface in the house so I used that for the joining on the jigs. The left wing panel at the LE was raised about 1/2" above the middle jig but a few sand bags when sheeting seemed to lock it back to the right place.

For the ailerons, since I added a bay, I needed some 36" 3/8" sq. stock as the kit only came with 24 and you need 25"!
