The invention relates to miter saws and in particular to a miter saw and a fence assembly for supporting a workpiece during cutting of the workpiece.
Compound miter saws, typically include a base having a support surface for supporting a workpiece and a turntable mounted on the base for pivotal movement about a vertical axis. A saw arm is supported by the turntable for movement therewith, and a fence is supported by the base to provide support for a workpiece on the support surface during cutting of the workpiece. The saw arm has a saw blade and is pivotable about a horizontal axis between non-cutting and cutting positions. If it is desired to engage in compound miter cutting of the workpiece, the saw arm is pivoted about a horizontal bevel angle axis to allow the user to make the angular cuts in the workpiece. In some prior art miter saws, to provide sufficient clearance for the blade of the saw arm and yet provide adequate vertical support to the workpiece during the cutting of the workpiece, the end of the fence adjacent the saw blade has an angular edge portion. The angular edge portion is intended to provide support for the workpiece while also providing clearance for the saw blade during compound miter cutting of the workpiece. It is known in the art to adjust the position of the fence toward and away from the saw blade to allow cutting at extreme bevel angles and yet provide support to the workpiece.
