The mechanism comprises an arcuate guide means adjacent each of the side edges intermediate the pair of side walls and disposed on a circular axis having a common center point. The guide means have a diametrical pivotal base member pivotally secured on the center point below the flat top surface. Support guide means is secured to the pivotal base member and extends transversely above the flat top surface and displaceable along an arcuate path between each pair of side walls. The support guide means each have a saw blade guide slot axially aligned on a common diametrical axis extending across the opposed side edges and passing through the center point. Arresting means is also provided to immovably secure the pivotal base member at a desired position along the arcuate guide means.
