This was a lot easier than I expected. The page calls out for fabricating Actuation Brackets and Pivot Brackets out of extruded aluminum, and VAF had several comments about the amount of time this would take. To my pleasant surprise, I discovered that the parts are already machined and ready to install, so steps #1 and #2 are pre-completed. The other steps involved very easy fluting of the ribs that will hold the counterweight and support the leading edge of the flaperons.
