THIRD.

Set the gauge, Fig. 42, to the width given in the drawing, and gauge a

line from the face edge on both sides; then plane to the gauge lines.

[Illustration: FIG. 43.]

In using the gauge see that it is held as shown in Fig. 43, and push

away from the body, having the pressure on the gauge as shown by the

line A, B, Fig. 44. This will keep the head of the gauge close to the

work. Do not try to mark a line by holding it as in Fig. 45, with the

spur at right angles to the work, as it will generally follow the fibre

of the wood and a crooked, ragged line will be the result. By holding

it as shown in Fig. 43 (and gently letting the spur touch the work,

going over it once or twice until the line is of the desired heaviness

to work to) a clear, clean-cut line will be obtained.
