It consists of upper and lower wheels with a table to support the work between them, a band saw with a continuous flexible blade rotates around the wheels. Release the tension on the blade, wrap the blade around the lower wheel and then around the upper wheel, making sure the teeth face down towards the top of the table. When the saw blade stops moving, mark the table with a pencil along the edge of the scrap piece. Loosen its set screws and adjust them so that they are the thickness of a piece of paper away from the blade. If you cut the curve and go through the cuts, the scrap will fall off and give the back of the blade room to move. First, loosen the blade locking screw from the top and adjust the thrust bearing so that it is about the thickness of a business card that does not touch the blade. Each time you change the blade, you should check that the blade cuts parallel to the thrust bearing. Finally, adjust the table so that it is perpendicular to the blade. To keep the saw blades on their wheels, band saws rely on guides above and below the table. With the right blade, a band saw can cut wood or metal in curves or straight lines. Before making cuts, adjust the blade guard so that it is about ½ inches above the shank. The size refers to the distance between the blade and the saw neck or column supporting the top wheel. For example, a good general-purpose saw blade may be ½ inches wide with three teeth per inch. If the scrap is properly aligned with the blade, you will feel that you are cutting straight without having to make major adjustments. For a band saw to cut better, the blade must be properly installed.
