With the prep work out of the way, I started to level the wing and align the skin.  These pictures show various stages of that process.

      These two pictures show the laser level targets I used – one at each end of the skin – to give myself a reference for the forward edge of the skin.  After the wing was leveled, I had to make small adjustments to the location of the skin in relation to the alignment marks.  In the end I had to settle for a compromise position that left the edges squared with the spars and about 90% of the holes centered over their alignment mark.  The minor misalignment of the remaining holes was probably due to transfer errors. The lines were visible, just not perfectly centered.
