Laying Out Rough Stock

The tools needed for this are the rule, try-square or steel square, a straightedge and a pencil.

Figure 2 shows the try-square and steel or framing square, and gives the names of the parts. The rule used may be the single-piece rule or the folding 2-ft. rule, such as carpenters use (Fig. 3). A straightedge is anything which has one of its edges straight.

Squaring: Across a Board

Directions: Measure off and mark the length of the piece required; measure off near the end the width wanted; at what is to become the other end of the piece, mark off the width as before. With the straight­edge, connect these points and draw a line through them (Fig. 4). With the try-square or steel square draw a line to limit the length (Fig. 5).

Thumb" Gauging

A second way to lay out the piece, where the first edge is fairly straight, is to thumb-gauge for width.
This is done as shown in Fig. 6. The pencil is held against the end of the rule and the whole is pulled toward the worker. The thumbnail of the left hand held on the rule at the desired point acts as a gauge head.
