On my ultra slow build -4, the front vertical fin spar missed the pickup tab on the horizontal stab front spar by half an inch. I understand this is fairly typical. The airplane was designed with pencil and paper and the various tolerances can add up. The upshot is that the fit of the supplied intersection fairing was laughable so I made a fairing by laying up 4 layers of carbon cloth over clay. It is thin, light and very stiff. Came out great but took a lot of time.
Should I use countersunk washers on the fasteners that hold it in place? Or will the composite hold up to an unsupported #8 screw head? I guess this fairing comes off at annual? Any comments appreciated, especially those based on long experience with older airplanes.
