Abstract: A router having a rotary bit is mounted on a table in a position to enable the bit to engage a workpiece on which is secured a template having a configuration corresponding to that to be duplicated on the workpiece. A template follower overlies and confronts the bit and has a socket in its lower end in which the tip of the bit may be accommodated to ensure that the bit and the follower are coaxial. The socket is defined by a side wall which is adapted to engage the edge of the template and thereby prevent engagement between the bit and the template.
