The first job today was to shape the sections of wood that will form the leading and trailing edges of the wing. The 3/8" thick stock material for the aileron spar and the inner section of the leading edge nose block had been supplied as 6" wide sheets so a combination of the bandsaw and the table saw were used to convert this to the sections needed. The aileron spar has an angle of 87 degrees on the lower edge and 80 degrees on the top edge. The inner nose block has an angle of 60 degrees on top and 79 degrees on the bottom. Angles up to 20 degrees can be cut on the bandsaw but above that the table saw is needed. After setting up the saw tables with fences and 
feather boards to hold the material test cuts were made on scrap material to adjust the sizes precisely. The final cuts were then made to exact size to butt precisely against the ribs and to require no further adjustment before gluing the skins in place. The aileron spar and inner nose block fit inside the wing skin. The outer nose blocks butt onto the front of the inner blocks and the edges of the skins. These were cut slightly over size and will be shaped by hand to form the leading edge shape. These were cut using the table saw from 1" x 2" stock. First this was resawn into two 7/16" x 2" sections and then the angles cut into the edges.Then the 1/16" ply reinforcing plates were glued to the sides of the spar roots. The second and third pictures shos the wing mounts in place. The ply and spar bushes will be drilled to secure these in place. It is important that the mounts butt tightly against the ends of the spars as many flight loads are compressive and this tight fit provides additional strength to the joints.
