Abstract

A chop saw has a saw unit connected pivotally about a horizontal axis to a turntable mounted rotatably in a base plate about a vertical axis. An indexing mechanism for locating rotational positions of the turntable comprises catch recesses on the underside of the turntable along a circular arc. A leaf spring is mounted on the base plate and has a free end engageable in the catch recesses upon rotation of the turntable. A release element is movably mounted in the base plate and operable to flex the leaf spring to move the free end thereof out of engagement with any catch recess engaged thereby. Advantageously the leaf spring and the base plate may be integrally molded or cast. Also, the catch recesses may conveniently be formed during casting or molding of the turntable.
