Abstract: A template for use with a jig having a workpiece positioning member. The template supports and guides a cutting tool used to cut joint members in two workpieces and comprises a support surface and at least one set of guides formed on the support surface for guiding the cutting tool. The support surface is movable with respect to the workpiece positioning member a predetermined distance between a first position to cut joint members in one workpiece and a second position to cut complementary joint members in another workpiece. This arrangement permits accurate routing of rounded or square finger joints or other types of uniform, spaced joints as determined by the template being used. Moving the template with respect to fixed workpiece positioning members means that no adjustment of the positioning members or workpieces is necessary between cutting of complementary joint members on separate workpieces which tends to result in more accurate cutting of the joints.

Abstract: Apparatus for guiding the movement of a hand held router relative to a workpiece comprises a support forming an upwardly facing base adapted to underlie and support a workpiece to be routed.
