Outboard rib W-7A was glued in and the aileron cut free. The 1/32 clearance gap is not enough for the aileron after covering and painting so I sanded the sides of the aileron and the gap is now about 1/16 which should be ok. Hate to have a finished aileron bind [&o]

Balsa blocks for the hinges were set then the leading and trailing edge balsa applied. Using the Robart hinge centering guide I drilled 3/16 holes for the hinged then marked the centerline of the aileron. planed and sanded the aileron was shimmed to center and the holes for the hinges were marked and drilled. Some "squaring" of the holes to set the hinged deep so there is no gap. The finished aileron looks good with plenty of throw and good clearance on the sides.
