Since I'm setting aside the flaps until I receive the backordered part, I decided to start working on the ailerons. The first step was to take out the punched pieces, remove their protective blue plastic vinyl, and write on their part numbers with a Sharpie marker. I also had to cut several apart using the bandsaw, since a few of the parts were still connected to each other in order to simplify Van's manufacturing processes. After that I used the Scotch-Brite wheel on the bench grinder to remove the rough saw remnants and smooth those edges.

What's next? Since I'll be traveling for a few days to Houston for a work event, I've packed a small box with these parts and some supplies (deburring tool, metal files, and scotch-brite pads) so that I can try to get some progress done while sitting in the hotel room in the evenings.
