Abstract: A portable, double bevel, combination table saw and slide miter saw comprising a horizontally disposed working platform with an elongated slot, is supported by a frame. A saw assembly is pivotably mounted beneath the working platform, with a saw blade that protrudes through the slot to cut a workpiece on the platform whereby stationary workpiece operations as well as moving workpiece operations may be executed. The stationary workpiece operations are executed from one side of the platform, and moving workpiece operations are executed from the opposite side of the platform, with separate appropriate controls on each side. The possibility of interference between saw assembly parts and the underside of the work platform inherent in double bevel configurations is avoided by the self-adjustment of the maximum depth for the workpiece bevel cuts.
