CROSSCUTTING

Cutting directly across the grain of a piece of lumber is called crosscutting. Fig. 14 illustrates a crosscut operation. Position the work so that the cut will be on the left, as shown.

RIPPING

Cutting wood lengthwise is referred to as ripping. This operation is performed in the same manner as crosscutting with the exception of supporting the material to be cut. If material is supported on a large table, bench or floor, several pieces of scrap stock approximately one inch thick should be placed beneath the material to allow clearance for the portion of the saw blade that extends through the material. Large sheets of paneling or thin plywood supported on saw horses should have 2 x 4’s placed lengthwise between the horses and the material, to prevent it from sagging in the center.

For narrow rip cuts, the rip guide, available as an accessory can be used. The saw is guided by keeping the inner face of the rip guide, Fig. 13, tight against the edge of the board.

For making wider cuts, such as might be made in plywood and wide sheets, a wooden guide strip or a commercial cutting guide can be tacked or clamped to the work. The left edge of the saw base can then be guided, as shown in Fig. 15. NOTE: The line of the cut must be adjusted to allow for the width of the guide.
