ABSTRACT:
A precision router guide for guiding a router in the formation of grooves, slots, steps or other cutaway sections of various widths in a work piece. The precision router guide includes a rectilinear guide member with an integral clamping assembly for securing the guide member to a work piece, and an adjustable template assembly adapted to be slidingly coupled to the guide member. The adjustable template assembly is configured to receive a router base, and has provision for the router bit to extend through an opening into engagement with the work piece. The adjustable template assembly also includes two adjustable guide elements and one fixed and one adjustable stop designed to allow adjustable movement between the router base and the template assembly in a direction perpendicular to the guide member, the amount of such movement being determined by the desired width of the cut. Adjustable pointers are provided on the template assembly to enable the groove, slot, step or other cutaway section to be precisely located on the work piece.
