Abstract: A jig for holding a workpiece on a cut-off saw includes a work-engaging wall adapted to extend transversely to a support table of the saw and be disposed between a backup plate and clamping plate of the saw. A guide pin secured to the work engaging wall extends into a guide groove on the support table, and an angle-setting projection, which can be adjustable, on the work-engaging wall extends toward the backup plate on the table to set the angle at which the workpiece is cut by the saw.
