Aligning wings, lessons learned - 2 hours

So happy with the alignment and level, I cleco'd on the top of the wing skins to the spar. Overall the alignment is good, just tough the get the holes closest to the inboard side of the spar to line up. I appears that there is still an amount of bow on that side. I will have to address that somehow.

Then, it became very clear that the wing skeleton was not square as it was skewed like a trapezoid and the rear spar holes were about 1/2" out. Haha...I spend quite a bit of time to remove the skew out out of the wings and clamp the rear spar t have to remove it and do it all again.

I also noticed that the level was just ever so different on the inboard end of the wing spar. According to my measurements....The thickness of the Main Spar doublers are different. I see on the build logs that everyone places a level on the top. However on my spars, the thickness of the spars are not the same, so the bottom if the spar (or aft face of the inboard end) is the best place to represent level. The forward face of the outboard end of the spar is the best place to check level though.

More adjustments where made. I reset level and decided to call it. I'm becoming irritated.
