is faster when resawing multiple pieces. Use a push stick as you near the last 3″ (76 mm) of the workpiece. Make sure the stock is supported behind the blade. 23.9 Scroll Saw The scroll saw cuts small radius curves. Its thin, narrow blade saws intricate work, such as marque- try and inlay. A scroll saw operates much like the band saw. However, unlike a band saw, the scroll saw will cut out pockets (interior openings). 23.9.1 Scroll Saw Parts Scroll saw parts include a table, hold-down, blade clamps, blower nozzle, and a guard. See Figure 23-54. The table tilts to make bevel cuts. A hold-down keeps material from vibrating on the table. It is attached to the machine frame or to a guidepost. The blade, held by two clamps, cuts by moving up and down. The lower chuck drives the reciprocal motion of the blade. The upper chuck is spring-loaded and retains blade tension. A blower nozzle is attached to an air supply line. It blows away chips so the cutting line remains visible. The majority of scroll saws are rear-tension saws. With rear-tension scroll saws, the entire overarm piv- ots as the blade moves up and down. Blade tension is adjusted at the rear of the machine. The advantage of rear-tension saws is that the blade moves slightly back from the workpiece. This helps prevent the workpiece from jumping up and down. The hold- down serves as a guard for rear tension scroll saws. Patrick A. Molzahn Figure 23-53. Resawing on the band saw is a one-pass operation.
