The drawing, [Fig. 21], calls for a piece that is 8 inches at its longest, 2 inches at its widest, and 1 inch at its thickest point, and that may be designated thus: piece 8 inches × 2 inches × 1 inch finished.
For measuring, a standard rule 2 feet long that can be folded up is preferred. The rule is divided into feet, inches, ½ inches, ¼ inches, ⅛ inches, ¹/₁₆ inches, etc. On some rules will be found scales that can be used in measuring drawings that are drawn to scale. The drawing may be of any scale, using ⅛, ¼, 1, 1½, 3, or 6 inches to the foot.

The first thing to be done toward carrying out the work is to saw out a piece from the plank that is laid on the saw trestles ([Fig. 27]). Mark with a pencil the lines to be sawed; holding the rule in the left hand, and the pencil in the right, and placing the index finger of the left hand against the edge of the plank, as shown in [Fig. 28], draw both hands toward the body, thus marking out the piece lengthwise; then measure the length required and place the try-square ([Fig. 29]) against the edge of the plank, and draw a line along the blade through the point marked.
The piece should be marked out larger than the finished exercise so that there will be stock enough in the piece to perform the operations required, say 8½ inches × 2½ inches, the plank being thick enough to provide for the work on the sides.

Having “laid out” the piece on the plank, take the rip-saw and hold it as shown in [Fig. 30]: saw down the line, taking care that the “kerf” is square to the side of the plank; then take the cross-cut saw, and saw across the line marked. Hold the cross-cut saw as in [Fig. 30].
After having cut the piece from the plank take the jack-plane and put it in good condition for work. A sectional view of the Bailey Iron Plane is shown in [Fig. 31], and the parts are as follows:
