ABSTRACT:
A chuck and methods of chucking or clamping a workpiece for multiple machining operations without requiring rechucking or repositioning of the workpiece employs an arcuate cradle for supporting the workpiece with an abuttment at one of its ends. The workpiece is slid along the cradle until one of its ends is stopped by the abuttment, and then a jaw is pivoted against the other end of the workpiece to securely clamp the workpiece under hydraulic force derived from a machining tool to which the chuck is attached.
