For the beam blocking pieces, you can either use a solid piece of 1/2" x 1/2" balsa, or laminate together two pieces of 1/4" balsa, like that leftover from the end-ribs. Measure carefully, and cut the ends off a 45-degree angles using a razor saw. Also, you will need to make a beam "nose piece", out of similar wood. Make the nose piece the same width as the beam, but the height and length can be estimated as you'll be sanding it to the airfoil anyway.
