I spent a little time disassembling some of the clecos from the left flap so that I could finish match-drilling the last hole in the flap hinge bracket that was too close to the skin to drill. I then deburred the two holes in each of the nose ribs that had been previously match-drilled through the nose skin.
After deciding to make some progress on the right flap, I fetched all of its pieces from my shelf and clecoed all of its parts together. Nothing too eventful, but it went quicker than the left flap since I knew what to expect this time.
What's next? I didn't have time to start on any of its match drilling tonight, but I'll get to that tomorrow and that should bring both flaps to the same state of completion.
