A stop for a tool that engages a work piece on a work platform includes a mounting assembly that can be movably mounted on the tool so that the mounting assembly is selectively positionable on the tool. A first member is operatively connected to the mounting assembly and projects outwardly from the mounting assembly. A second member projects from the first member to engage and locate the work piece with respect to the tool. The second member is mounted on the first member for movement along a length of the first member and is selectively fixed to the first member to adjust a distance between the second member and the mounting assembly.
