Two of the wood strips that I cut last week were marked up, drilled, and countersunk to attach them to the front and rear of the ribs. Then each rib was match drilled front and back with a guide hole to take #6 wood screws. The inner leading edge strip was then screwed and glued to the front of the ribs, then the aileron spar was screwed and glued to the rear of the ribs. Next triangular sections of wood with one right angle were cut to length to make corner blocks which will secure the ribs to the main spars and to the leading edge and aileron spars. Using a jig in the drill press to locate the triangular sections nose down, the blocks were then each drilled in two places to take panel pins which will secure them to the spars while the glue dries. I made enough blocks for both wings, the ones for the left wing are in the plastic bag in the foreground of the picture - lots of cutting and drilling.
