Clamp mechanism for use in maintaining a workpiece in desired position against a stationary backstop including a clamping member mounted for free linear movement for being positioned in engagement with the workpiece regardless of the dimensions thereof and a camming and locking device for selectively engaging and camming the clamping member to apply a desired clamping force to the workpiece and for locking the clamping member against the free linear movement thereof in the cammed position. This preferred clamp mechanism may be utilized in an apparatus for cutting the ends of workpieces, e.g. mitered end picture frame moldings, and which includes a table top linearly movably mounted on a support frame and having a longitudinally extending slot therein and a saw mounted in fixed position within a portion of the table top slot. The backstop and clamp mechanism are mounted on the table top with the backstop disposed at a predetermined desired angle to the saw for clamping the workpiece on the table top for movement toward the saw for the cutting of the end thereof.
