Paragraph 14. In forming tenons for mortise and tenon joints, the tenon should be sawed to the gauge line, as shown in Figure 31. The material should be fastened in the vise at an angle; this will make it more convenient for starting the saw. In sawing wide tenons it is sometimes convenient to saw part way from one edge, and then reverse and saw from the other edge, thus enabling one to follow the lines more accurately. Sometimes the back saw is used for this purpose, but the large saw is more desirable for larger work.
