Added the bolts at the lower inboard .188 angle part. Spent most of the time finishing up the -6 length rivets (on the outer 9 rib bays). Got 10 of the -7's done, then screwed up the same rivet twice after drilling it out. Figure I'm tired, and drilling it out again I'm not going to get it right. Error was allowing the gun to bounce off the head, putting a strike across the center of the rivet head. Also now getting towards the root as the upper and lower spar cap extrusions get wider, there is less clearance for the bucking bar and rivet driver. Maybe next time I'll try the Sonex bucking bar (cut to fit around the spar caps). I think it's heavier than the one I'm using. Just passed 650 hours logged on the project.

Setup for the further in rivets. Moved to other side of table.
