Sanded the front ribs to contour using the plywood rib doublers as guides.
Sanded the butt ends of the rear ribs to ready them for gluing. Made a plywood template for the end rib that is angled to the spar. Cut and sanded the bevel. Prepared balsa "crutches" for fixing the ribs to the spar with CA glue during epoxy hardening. Glued all rear ribs to the main spar with cotton-cab mix.
