Not much work today, getting ready for holiday weekend guests, a trip to the hangar construction site, but then some progress. I finished riveting the delrin bearing and stiffener on the leading edge root rib, and then drilled and installed the fuel fittings in the main root rib. Including proseal. I decided to put the head of the rivet to the outside, in case I ever needed to drill them out. However, they were too close to the flange and it made pulling difficult. In hindsight, I would do it from in to out next time, keeping the rivet gun away from the flange.
