Abstract
The disclosed chuck has a cylindrical body and a mounting hub secured thereto for concentrically connecting the body to the powered spindle of a lightweight woodturning lathe. The body has a faceplate opposite the mounting hub, and radial grooves are formed in the body from the faceplate. Adjustment screws fit in the grooves, being rotatably held therein by spaced bearings, and chuck jaws are supported on the rotatable adjustment screws and project forwardly from the faceplate. Rotation of each adjustment screw thus moves the chuck jaw thereon radially of the faceplate and within the grooves to provide keyed gripping of a workpiece to be shaped by the lathe. The workpiece can be of virtually any cross section as each jaw can be independently adjusted. The chuck body is approximately 10 inches in diameter and 1 inch in thickness and is formed of wood to be light in weight, only approximately 3 pounds.
