Abstract
A miter saw is constructed to move a workpiece supporting fence between rearward and forward longitudinal positions relative to a saw blade, as well as the automatic transverse movement of the workpiece supporting fence relative to the saw blade as a turntable is rotated to selected miter positions. The workpiece supporting fence includes a T-shaped slot in fence supportng sections thereof and a pair of downwardly directed pins fixed to the underside of the workpiece supporting fence. A fence lock extends through the longitudinal portion of the T-shaped slot, to enable the fence to be moved between its forward and rearward position. The fence lock engages the fence in a repeatable and controllable locking action. The downwardly directed pins are positioned within a pair of generally parallel openings in the turntable, there being one opening on each side of a saw blade slot. When the workpiece supporting fence is in its rearward position, one of the pins engages peripheral areas adjacent a curvilinear portion of its associated opening in order to move the fence from side-to-side as the turntable is rotated for selected miter cuts. When the workpiece supporting fence is in its forward position and the turntable is rotated, the opening moves relative to the pins, without engagement therewith. Thus, no relative transverse movement of the fence to the saw blade is required when the fence is in the forward position.
