EXERCISE NUMBER 9.
BENCH HOOK.
(This exercise may be omitted at the option of instructor.)
It will not be necessary to give many directions for this exercise, as the student by this time should have learned the sequence of operations in preparing material. The special points to be noticed in the working out of this exercise are that the sides are cut out with the rip-saw; the ends cut with the back-saw; the sides to be finished with the plane, using the rabbet plane to plane the corners at the stops at the ends, and the jack-plane for the rest of the surfaces. Surfaces are to be finished with sand paper and shellaced.
In Fig. 112 will be seen the working drawing. The thickness of stock required is 1¾ inches. The angle at which to set the bevel for the ends is ½ inch in 4 inches. All the other dimensions are found on the drawing.
After the piece is cut out and finished with sand paper, give it a coat of shellac varnish and let it dry from 8 to 10 hours. Then with No. 00 sand paper smooth the shellac (but do not cut through). After which give another coat. To obtain a glossy surface the pores of the wood must be filled with the varnish; by repeating the operation with the sand paper and giving another coat of shellac, a very good surface will be obtained.

Care must be taken in putting on the shellac varnish not to put it on too thick, as it sets or dries quickly and an uneven coat of varnish is unsightly. Spread it quickly; see that plenty of shellac is on the brush; do not go over it after it has once been spread evenly, as it will roll up in small lumps which will have to be left to dry before anything can be done to it, and then it will take a great amount of labor to smooth it.
This is one method of finishing with shellac varnish.
