A mechanism for clamping a banjo toolrest or toolrest bracket to a lathe bed which makes use of a sliding cam which is actuated by a drive shaft. The cam is supported independently of the drive shaft by a support block resting on a ledge which is formed in the base of the banjo. The cam is slidable with respect to the drive shaft along the length of this ledge on the banjo. This structure allows for sturdy clamping with minimal deflection at a predicable catching position along the length of the banjo rest. An eye bolt is used to connect the cam to a clamping plate which is positioned below two, spaced-apart rails extending along the top of the lathe bed. The banjo rest has a generally open bottom through which the shank of the eye bolt extends. Opposite ends of the drive shaft are rotatably supported by end walls of the banjo rest.
