Finished riveting the left wing spar cap. Rivet front flange of ribs that had to be removed to replace the spar cap. Fitted the wing root doubler. Drilled holes to mount it and located and drilled holes for the 6 AN-5 bolts to mount the wing spar to the center section spar. Reamed those holes for the bolts, but left them a snug fit. Final reaming to size when the wing is finally put on.
