First today, the fuselage was levelled fore and aft and left to right and chocked in position. Then the wings were bolted into place and the dihedral set to zero as per the plans. All the measuring I'd done
http://tailwindbuild.blogspot.com/2009/09/15th-september-2009-rib-rework.html paid off as the front and rear spar spacings exactly matched the fuselage brackets on both sides and the spar attach bolts slid comfortably into place in both the wings. A block was cut to create an exact level between the front and rear spars of the right wing
. This wing had both the front and rear spar attach brackets bolted into position so provided the reference for setting the incidence of the left wing. On the left wing the rear spar attach bracket had not been drilled to the spar so the incidence of the left wing could be set precisely the same as the right. This was done and the bracket clamped into position and then drilled through the bushes in the spar and bolted into its final location.
