A rule with which to lay out your work and measure your stock is one of the first tools of which you can make use. A two-foot rule, folding once, is the most convenient for shop-work, but the more common kind, folding to six inches in length, is more convenient to carry around away from the shop. One brass-bound (with brass edges) is more durable, but hardly as convenient to use as the common cheap kind, which will answer every purpose until it breaks.

To mark distances with the rule for accurate work, lay the rule on edge so that the divisions marked on it will touch the wood and not be an eighth of an inch above it, as they are when the rule lies flat (Fig. 650). You can thus mark the points more accurately.
