I'm still making preparations prior to riveting the bottom wing skins on. I have decided to run string through the conduit so I can pull the necessary wiring when I am ready to hook up the lights, Pitot tube heat controller and the roll servo. I built a stand that supports a vertical 4 X 4 post to hold the wing skin out and away for improved bucking access. I realize now that I will have to move the wings back to the building jig to make it easier to set the rivets between the wing walk ribs to the aft spar. The wing cradle positions the wings with the leading edges facing down. The building jig will face the leading edges up and allows me to better position my bucking bar to set the difficult first few rivets.
