This evening I used the water trick with the plumb bobs to great success. They are less than 1/32 off from end to end. Then I located the sheet of aluminum for the wing walk doubler and drilled it per the instructions, using the inner top wing skin for a pattern. Just before quitting for the evening, I clecoed the top skin on the left wing. I also marked 2 pieces of 1/2" plywood for the nose rib cut out and gave them to Jim to cut them out, since he had my jig saw.
