Several inches of excess length on the inboard hinge pin permitted enough length to flattened the end somewhat with a hammer on a anvil. Repeated hammering on the end widened the pin end enough to be very snug in the hinge knuckles. Chucked the opposite end of the pin in a battery powered hand drill and used the flattened end as a reamer to open the clearance of the hinge knuckles slightly (tip learned at Jeff Shultz firewall forward seminar).
Same treatment to the outboard hinge knuckles. Cut and bent the inboard hinge pin. Pin fit for inboard and outboard hinge pins can be inserted freely, but remain snug.
Sanded areas of primer to smooth pebbly surface. Added lightweight filler to close several holes in aileron skin.
