ABSTRACT:
Alternating contour mating surfaces on two workpieces are produced by a working tool, for example a router bit of a router, by rotating the working tool and displacing it relative to the workpieces with guidance of the tool by a base member which has a first substantially flat surface and a second surface which is spaced transversely from the first surface and has two surface portions offset relative to one another in a transverse direction.
