A lathe is the appropriate tool for turning wood stock because it is specifically designed to rotate the material while cutting it. This allows the user to shape and refine the wood into various forms, such as spindles, bowls, or intricate designs. The lathe holds the wood piece securely in place and enables the application of various cutting tools, making it ideal for producing round shapes and smooth finishes.
In contrast, the other tools listed serve different purposes. A drill press is used for drilling holes with precision and cannot achieve the shaping needed for turning wood. A table saw is primarily designed for making straight cuts along the grain of the wood or across wider pieces, but it cannot create the rounded contours required in turning. The band saw, while capable of making curved cuts, lacks the rotational function needed for turning, making it unsuitable for this specific task. Thus, the lathe stands out as the best choice for properly turning wood stock.
