Got all of the center ribs trimmed, drilled, deburred and clecoed in tonight. Everything fit perfect.
I used small pieces of .032 clamped onto the rib at the rear spar to simulate the wing skins, this makes it simple to align the rear of the center rib. I checked spar web distances, level front to back, and level between spars before and after adding each rib.
You’ve got to be careful down at the root end of the main spar when checking level. The top cap strap is .25 thick and the bottom is .125. I threw the level up there and noticed it was .06 degrees off….and I was thinking about how to compensate when I realized what was going on. I small piece of .125 bar as a shim showed everything was good.
Looking like a wing again.
All that drilling and ribs in/out…..happy to see things still look good.
