Once the ribs and rear spar were on, we dropped a couple "plumb lines". There was very little twist at first, but we adjusted the bottom attach brackets until it was perfect...

...and clamped the rear spar in place.

Then we did the same for the right wing.

We've got the inboard skin on the top of the left wing.

All the lightening holes line up.

...started clecoing on the inboard skin on the top of the right wing.

Got the main skins on top of both wings. I'm gonna need a lot more clecos. I only bought 300 when I originally shopped for tools. That's not going to be nearly enough.

...an action shot.

The underside view is pretty slick.
