Kieran and I drilled out the pop rivets holding the aileron skins on near the hinge area to allow access for mounting the hinges to the aileron. We sanded some paint off the aileron hinge fittings, then pressed the spherical bearings in place. We used various socket wrenches and a C clamp to press on the bearing housing until it slid into the hinge bracket. If it was too tight, we used the same technique to press the bearing out of the hinge bracket, sanded a little more, and tried again for a press fit.

It looks like we will need to drill the holes for the aileron hinge points and also on the mounting flanges for mounting the aileron hinges to the ailerons. Then, hold the aileron in place while marking the locations of the hinges on the aileron spar. Then drill the holes for attachment of the mounting flanges onto the aileron spar, before bolting them in place. I'm going to check with Avipro before doing the drilling.
