placing a piece of 1/4″ (6 mm) hardboard on it. Screw or nail the hardboard to the saw table, away from the blade’s travel. After replacing a damaged table protector or fence, you must recut saw kerfs. This must be done through the fence and across the table for crosscutting. Later, kerfs may be needed for miter and bevel settings. 23.7 Sawing Curved Lines Stationary machines that cut curved parts include the band saw and scroll saw. Both machines have narrow blades that allow the saws to cut curves. See Figure 23-39. Choose a band saw for cutting large radius curves and large cabinet components. A scroll saw, with its smaller blade, is best for small radii and intricate curves. Patrick A. Molzahn Figure 23-38. Beveling with a radial arm saw. Patrick A. Molzahn Figure 23-36. Warped stock can present problems when cutting on a radial arm saw. A—Position bowed stock with the bow up to prevent pinching the blade. B—Stock with crook can be shimmed with a block of wood if necessary so the stock does not shift when cut. Patrick A. Molzahn Figure 23-37. By raising the saw above the table, boards can be kerfed on a radial arm saw. A—Repeat cuts are made at the same distance between each cut, leaving approximately 1/16″ (1.6 mm) of material. B—Kerfed parts can be bent to tight radii. Shim A A B B Chapter 23 Sawing with Stationary Power Machines 389 Copyright Goodheart-Willcox Co., Inc.
