Abstract
This invention provides a frictional clamping arrangement for holding the workpiece being cut by a router so as to prevent movement of the cutout portion of the workpiece in the last increment of the cut. The device includes a pressure foot having a clamping member which is forced downwardly against the surface of the workpiece when the cut is nearly completed for holding the cutout portion of the workpiece motionless relative to the worktable so as to prevent its lateral movement during completion of the cut. The clamping member is fixed relative to the spindle during the principal part of the cut, but is released for limited movement relative to the spindle when holding the workpiece.
