7/19/23 - 1.2h Step one in this section is installing the hardware to attach the ailerons to the wing. This was just a temporary attachment in my case since I plan to remove the ailerons before installing the bottom wing skins. I installed all of the hardware, but just left the nut finger-tight. The drawings in this section of the plans are very good to show exactly how the hardware is arranged within each of the aileron hinges. The washer closest to the bolt head on both the inboard and outboard hinges has the potential to be installed incorrectly, though. Those washers do not go directly under the bolt heads, rather they go in the very narrow space between the aileron hinge brackets and the wing hinge brackets. I noticed that arrangement after installing the first bolt incorrectly, and it should definitely be inspected for correct installation every time the aileron is removed and installed. I started each hinge installation by using a thin pick to get all of the washers in place before installing the bolt. The first trick (working from the outside in) was the set of double washers on the outboard hinge. I threaded a strip of wire lacing tape through the washers, and then used the lacing tape to suspend the washers in line with the hinge holes while I inserted the thin pick. The washer just inside the hinge from the bolt head is the next tricky one to deal with since it is tough to get to. I used a small standard (flat blade) screwdriver to hold the washer in place while I threaded the pick through the hinge holes and the washer. Once I had all of the washers and bushings inserted in the right areas on the pick, I slowly pushed the pick out of the holes with the bolt to get the washers on the bolt. The end result is an aileron installation that moves freely with very little length-wise play due to the tight tolerances of the washers. Nice!
