Next I edge-glued a 6" and 2" wide sheet (The hobby shop didn't have the 4" sheet I wanted)

Then I glued the sheets in place.

I used mostly wood glue, but I put a drop of CA on the spar at each rib so I could secure the spar area first.

Once that was secured, I layed the sheeting down over the back of the wing.

And look!!! I finally found a good use for the AMA Magazine!
