The main portion has at least one workpiece engaging face, a first side and a second side. A passage extends through the main portion perpendicular to the longitudinal axis from the first side to the second side. The passage is positioned and configured to receive a flexible clamping device which is used to clamp the at least one workpiece engaging face to a workpiece. The tongue has a first face, a second face, a first side and a second side. A threaded aperture extends through the tongue perpendicular to the longitudinal axis from the first face to the second face. A set screw engages the threaded aperture.
