Get a Grip on Stock With the Four-Jaw Chuck

Chucks also can grip most common sizes of turning squares. Because square stock cannot be held as securely as round stock, hold it with the chuck and support it with a tail center, as shown at right. Then turn a round spigot on the tailstock end. Now flip the square end for end, and grip the spigot in the chuck, once again supporting it with the tail center. When you cut square stock for mounting in a chuck, make accuracy a priority; out-of-square stock is difficult to grip securely. The slightly rounded jaw corners of Oneway chucks offer the best design for gripping square stock.
