ABSTRACT:
A motorized saw for cross-cutting and mitering elongated workpieces mounted for sliding movement on a pair of spaced parallel guide rods supported by spaced trunnions attached to the ends of a support arm. The support arm is rotatably mounted intermediate its ends on a frame and has a worktable fixed thereon which includes a cutting channel that defines the pathway of travel of the saw. A pair of aligned fence members have their adjacent ends disposed in close proximity with the cutting channel and by means of a link rod operatively connected to each fence member and support arm, the fence members automatically adjust themselves to the cutting channel on selective movement of the support arm to a position for effecting a desired angle cut by the saw.
