Drop the wing upside down into your newly constructed saddle and weight it down to keep it from shifting around too much. (I use sand bags for this.) In order to position the wing accurately simply line up the main wing spars with the marks on the saddles.

Add the remaining 3/32" vertical grain shear webs to the back side of the main spars and to the front side of the rear spars as shown on the plan.

Install the R7a and R8a doublers to their respective ribs. These should fit tight up against the top wing skin as shown above.
