Figs. 6-8.
Some Forms of Bench-stops.
One of the simplest forms of stops is shown in Fig. 7. It consists of two screws placed in the top of the bench, which can be raised or lowered with the screw-driver to the height you desire.
The stop shown in Fig. 8 is made out of a block of wood with a "bird's mouth" cut in one side. It should be nailed to one end of the bench in such a position that the end of the work can be placed in the "bird's mouth."
While most of your work will be done on the bench, and a good portion of sawing done with the wood in the vise, large pieces, especially long boards, are generally sawn while placed across horses.

Fig. 9.
Two Carpenter's Horses will be required. A good scheme for these is shown in Fig. 9. The top is made out of a piece of two-by-four with bevelled mortises cut in two sides of each end as in Fig. 10. These mortises are made to receive the legs, and the angle of the bevel will of course determine the angle at which the legs will spread. Cut the legs out of four-inch boards, and bevel the lower ends to make them set solidly upon the floor. Nail the legs firmly in place and brace them with two boards cut and fitted in place, as in the illustration. When the pieces have been nailed together, plane off the tops of the legs to make them flush with the top of the horse, and trim the lower ends if they require it until the horse is solid.

Fig. 10.
Boring, paring, and nailing on the bench will soon make the surface uneven, unless something is placed beneath the work during such operations. You should therefore make and use
A Bench-hook, such as shown in Fig. 11. A good size is ten by twelve inches, but it may be made larger or smaller if desired. Nail a strip along one edge of the under face and another strip along the opposite edge of the upper face. The latter strip should have three kerfs cut in it as shown in the drawing, one at right angles and the other two at forty-five degrees. These may be laid off with a try-square, as shown in Figs. 38 and 39 (Chapter II), or with the bevel, as shown in Fig. 42. Be careful to keep the saw on the line and in a perfectly perpendicular position in making these kerfs. The upper strip on the bench-hook serves the purpose of a stop, and the kerfs make it possible to use the bench-hook for mitring with the back-saw. Further description of the uses of this handy article will be found in the following chapter.
