The wide piece was next planed on its sawed edge, and the blocks screwed on. That the bench hook might always be handy and have a definite place of its own, a half-inch hole was bored as shown in the illustration, and it was hung on a nail, set in the end of the bench.
The bench hook is designed to protect the bench from saw marks and the cuts of chisels, gouges, etc. The method of using it with the saw is shown in [Fig. 91]. Wherever possible, it should be made of hard wood.

THE EQUIPMENT FOR A SHOP
Nothing is so necessary to the saving of time and energy as an orderly shop. Our boys had bought a quantity of white pine to begin operations and it was lying in a pile on the floor where it was always in the way.
To cut a piece of stock from one of these 12-foot boards it was necessary to use two kitchen chairs for trestles, so it was decided to construct two saw horses, and as soon as they were finished, to build a lumber rack against the wall where their little supply could be stored out of the way.
"We will carry out our regular practice by first making a drawing," said Ralph. "We know from experience that it saves time."
[Fig. 92] shows the proportions of the trestle at a, and the mechanical drawing with all dimensions at b.
The body of the trestle was built up of four pieces, two long and two short ones. The open space in the centre, Ralph explained, would make a convenient tool rack where hammers, chisels, etc., could be placed while they were working, especially at outdoor work, instead of being dropped on the ground. The body then called for two pieces 3 feet long by 4 inches wide, and two pieces 10 inches long by 4 wide.
