This was a big day in my workshop. A fellow homebuilder and neighbor came over and helped me dismount the wings from their assembly racks, and remount them on the fuselage.
When installing the left wing, I was somewhat bumfuzzeled because the wing was about ½” short of allowing the spar pins to engage, even with the upper wing skin against the fuselage structure. After scratching my head for a few minutes, I remembered that the wing walk doubler would not be trimmed to the fuselage until later in the process, and needed to be removed for the wing to properly engage. With the removal of a few clecos and the doubler, the problem was eliminated and the wing slid neatly into position.
The right wing slid into position relatively easily. The right pin fit the right wing a little tighter than the left pin, requiring light tapping with a small mallet to drive the pin home. This may improve when the wing guides are aligned, or when my temporary spar pins are replaced with the SPA pins.
