Claim:
A combination angle bisecting tool and miter saw comprising: a) A tool for bisecting an angle formed by two convergent surfaces including: (i) first and second elongate framing arms pivotally coupled to each other at an end thereof, whereby the framing arms can be positioned adjacent to the converging surfaces of an internal angle; (ii) first and second extension arms attached to or which may be attached to said first and second framing arms providing a means for extending the first and second framing arms alone their respective longitudinal axes and across their pivotal coupling whereby the extension arms can be positioned adjacent to the converging surfaces of an external angle; (iii) first and second support links, each pivotally coupled to a framing arm at a point which is equidistant from the pivotal coupling and outside edges of the framing arms, the support links being pivotally coupled to each other at a point equidistant from their respective pivotal coupling with the framing arms; (iv) fastening means for temporarily setting the first and second framing arms in a desired angular relationship facilitated by the pivotal coupling of the first and second framing arms, pivotal couplings of the first and second support links to the first and second framing arms, and the pivotal coupling of the first and second support links to each other; (v) at least two positioning members extending substantially perpendicular to the plane of the tool whereby the axis formed between the positioning members bisects the angle formed by the coupling of the first and second framing arms; and b) a miter saw including: (i) a rotatable planar work surface; (ii) a stationary guide fence for supporting the work piece in an angular relationship for cutting with a saw; and (iii) receiving means for the at least two positioning members in the rotatable work surface, whereby alternate rotation of the work surface such that the first and second framing arms abut alternate sides of the guide fence positions the work surface for cutting a work piece along the axis formed between the positioning members.
