ABSTRACT:
A miter saw clamp accessory to facilitate vertical and/or horizontal clamping of a workpiece against a supporting worktable and fence is disclosed. The miter saw clamp accessory includes a pair of extension rods extending laterally outwardly from one end of a frame with a clamp support mounted on such extension rods. A clamp shaft is adapted to be mounted in a top opening of the clamp support for vertical clamping or in a side opening of the clamp support for horizontal clamping of the workpiece. A clamp assembly is mounted on the clamp shaft and includes a connecting arm for adjustable mounting of a clamping arm having a workpiece clamp at one end that is arranged for confronting opposed positioning relative to the frame for vertical clamping or to the fence for horizontal clamping of the workpiece. A miter saw crown molding jig accessory is also disclosed for mounting on a miter saw frame. This accessory includes a shaft mounted immediately adjacent to the worktable fence and a clamp head that is adjustably mounted on the shaft and includes a vertically extending bearing surface and a horizontally extending upper shoulder which overhangs the vertically extending bearing surface. The clamp head is moved on the shaft until the horizontally extending upper shoulder rests on a top edge of the crown molding while the vertically extending bearing surface engages a side edge of the crown molding in alignment with the worktable fence.
