ABSTRACT:
A horizontal base including a plurality of side by side horizontally spaced apart parallel guides is provided and a follower is selectively removably engageable with any one of the guides for guided movement therealong. A workpiece support is rotatably supported from the follower for angular displacement about an upstanding axis substantially normal to the plane containing the guides and the base is stationarily positionable on the horizontal table of a band saw or jig saw and a workpiece to have a constant radius arcuate cut made therein may be supported from the workpiece support and angularly displaced therewith in order that the blade of the saw may make the desired arcuate cut. The spacing of the parallel guide with which the follower is guidingly engaged from the blade of the saw determines the radius of curvature of the arcuate cut to be made.
