Abstract

A precision router guide is described which is specifically configured for cutting or routing out slots of different widths in panels, boards or the like. The precision router guide includes a plurality of frame members pivotally joined together near their respective extremities to form a parallelogram wherein two of the frame members are longer in length than the other pair of oppositely disposed frame members and have straight edges and are disposed in edge-to-edge facing parallel relationship, securing means for securing one of the frame members to the workpiece thereby placing the frame member in relatively fixed relationship thereto, gauge means adapted to operably set a specific reference displacement between the longer of the frame members whereby the distance between the respective gauge means establishes the precise width of the routers cutting swath on the workpiece, locking means for locking at least one of the pivoting joints of the parallelogram following the use of the gauge means whereby the distance between the two longer in length frame members remains fixed while the router's base plate is operably disposed in intimate guiding relationship between the pair of fixe…
