Fig. 180.—Second Operation in Sawing Tenons.
Fig. 181.—Cutting Channel at Shoulder of Tenon before Sawing.
To saw the tenons, place the rail in the vice as at [Fig. 179] and, with a panel, tenon, or hand saw, according to the size of the work, cut down the outside of the tenon line as shown. Reverse your position and cut as shown at [Fig. 180], then place the rail in a vertical position, and you will find little or no difficulty in sawing down square with the shoulder line. Repeat the above methods of sawing until all the tenons are sawn.
Next saw out the pieces at the side of the tenon by the following procedure. Place the rail against the bench stop, or in the vice, and cut a small channel in which to run your tenon saw as shown at [Fig. 181]. If you have scored the line deeply with your knife when you were marking out the work, you will have little difficulty in removing a small portion with the chisel. The amount removed in the illustration is, of course, exaggerated. In the small channel thus made place the tenon saw and, guiding the saw blade with the finger so as to keep it upright or square ([Fig. 182]), saw away the waste material. Remove the waste material at the sides of the tenons in a similar way, and then saw out the portion marked H, [Fig. 177], lower sketch.
The Mortising of the stiles may next be taken in hand by putting the stiles edgeways in the vice and boring away the bulk of the waste wood from the mortise with a suitable-sized twist bit and brace. This method will save a great amount of noise, as to a great extent it does away with the use of the mallet. Take the mallet and chisel and chop down about 3⁄8 in. as shown at [Fig. 183]; then turn the chisel to the position shown at [Fig. 184] and remove the small piece as shown. Continue these two operations until you are about half-way through the wood and then start in a similar manner at the line a, [Fig. 183], after which turn the other edge of the timber uppermost and repeat the methods shown.
