They're starting to look a lot like elevators now. The worst kind of riveting occurs on these, where you are barely able to hold bucking bar with your fingers (I have XL hands) through the corner of a rib with the skin bent up and blindly holding the bar to what you hope is the rivet head. It takes a little practice, but having tungsten bars is a huge benefit for these tight, blind spots. Other than that, it went pretty smooth and I finished step six by doing the MK-319-BS rivets on the bottom root rib. Next is closing out the trailing edge and the trim tabs.
