Machines of this kind are, in all kinds of shops, labor-saving devices. While many such machines might be omitted from a shop equipment, the time and cost for turning out work without them would be greater than if the machine were used, and in many cases hand work would be less accurate.

The usual power-tool equipment of pattern shop includes:

(1) Circular saw.

(2) Wood lathes, usually large and small sizes.

(3) Face lathe.

(4) Band saw.

(5) Hand planer, or jointer.

(6) Surface planer.

(7) Boring machine.

(8) Mortise machine.

(9) Scroll saw.

(10) Emery wheel.

(11) Grind stone.

The variety and quantity of work to be done in a shop determine its power-tool equipment, hence in many small shops some of the tools of the foregoing list may be omitted, while in the most extensively equipped shops some special tools not here named may be installed.
