I started out today by making the mounting bracket for the tip ribs to attach them to the wing stand. Once that was done, I realized how wide the wing stands actually were so I set about tearing down the spar shipping crate to give myself more room. I was able to save a lot of wood from the walls of the crate. I now have eight 1"x10"x3.5' pine boards instead of a 16 foot box with lots of staples sticking out of it. Not too shabby. After the house cleaning was taken care of, I grabbed the inboard top wing skins and the wing walk doublers to do a little match drilling. You'll notice the little yellow drill on the skin in the picture. That's my new best friend I think. It's light, powerful, goes forever on a charge, and is just a joy to use. I don't know how I didn't buy one of these puppies earlier in the project and get rid of the corded behemoth! Anyway, here is one of the skins and doublers getting match drilled.  After the doublers were drilled, I went ahead and clecoed on the top inboard skin to the left wing. Note the high-tech super-fancy wing sag remover (2x4 board that randomly happened to be the exact length I needed to take the sag out perfectly).  Why stop there? Let's go aead and throw on the outboard left top skin as well!  With the top skins clecoed on my wings transformed from a wobbly parallelogram into a rigid structure so I got that going for me, which is nice. At this point I leveled the spars both length-wise and width-wise to 0 degrees +-0.1 degree. Then I dropped a plumb bob from both the tip and root and measured the distance from the line to the rear spar. The tip and root measurements were identical so I know now that my wings are held on the stand without any twisting or warping. I did the same for the right wing but you'll notice I only have the inboard skin on. It's only got about 25 clecos in it because I ran out and couldn't continue.  After stopping, I came in and ordered 350 more clecos so I can continue fitting the skins. When those get here, I will cleco on the bottom skins and then match drill 26748 holes (approximately, of course).
