Sheeting the Top of the Wing:


2. Trim each end so the sheeting still slightly overhangs the root and tip ribs by at least 1/8”. (You might want to give yourself a little extra material as a “fudge factor.”)


3. Measure and mark 5/8” up across each end of the trailing edge of the piece, and using a long straightedge, draw a line. Use a sanding bar, held at a slight angle to the edge of the sheeting, taper (or bevel) this 5/8” section of the sheeting at the trailing edge, as shown in Figure 1:1 on the plan sheet. With each top and bottom piece beveled in this manner, the sheets can later be glued together to a relatively sharp edge without causing under-camber or similar deviations from the fidelity of the shape of the airfoil.

Left edge is tapered, beginning 5/8" ahead of trailing edge to a sharp point at the trailing edge.


Above picture did not focus well enough to show appropriate detail, so another picture is shown. Pictured is the bottom trailing edge sheet, tapered in the same way. (If you are noticing the background, please note that at this stage in the directions, the top sheet has not actually been glued down, yet.)
