I mounted the wing skeleton to the wing jig and supported the middle of the rear spar after making sure that the front spar was level. I did this by using a fishing line as other builders have done.
I cut the wing walk skin from the AS3 0.025, 10 x 48 sheet and match drilled wing walk using holes in top skin being careful to position wing walk per dimensions in instructions and drawing.
I then clecoed inboard top skin and wing walk doubler to wing spars and ribs.
