Skip joined me for tonight's session to man the bucking bar while I used the rivet gun to rivet the eading edge ribs to the main spar. This was a difficult but manageable task on the left wing even using solid rivets driven from inside the leading edge down through the spar. The right side was a bit more difficult, especially on the inboard ribs because there is no access hole to use for reach. Ultimately I gave up on using solid rivets for the 3rd inboard rib and have ordered some LP4 pull rivets from Van's to complete this.
