Abstract: The invention is directed to an arrangement for cutting contours in a workpiece with a router and includes a supporting structure and a pair of elongated vise members mounted on the supporting structure. The vise members are disposed in side by side relation to each other with at least one of the vise members defining a substantially smooth upper surface upon which the workpiece can be placed. At least one of the vise members is mounted on the supporting structure so as to be movable relative to the other one of the vise members. An elongated fence member adapted for insertion between the vise members is also provided. A clamping arrangement is included for adjusting the vise members with respect to each other to clamp the fence member therebetween. A mounting structure accommodates a router and is mounted on the fence member so that the mounting plate, the fence member and the upper surface of the workbench conjointly define a path for passing the workpiece therealong.
