Completed all match drilling, deburing, and dimpling of aileron skins and components. Cleaned all parts with Metal Prep, and primed with Epoxy primer.
Once dry, rivited left counterbalance to leading edge ribs, and that assembly to the aileron spar. Began riveting the leading edge and aft skins to the top of the main spar. This requires a fixture to securly hold the assembly (I used my vice with a piece of carpet in place) since you'll have to bend the bottom skin up and out of the way for the bucking bar.
