ABSTRACT:
A spring bias spacing attachment for a portable electric router is placed between the router motor and the base of the router. The attachment, which comprises two concentric rings separated by a series of springs, is slidably mounted over the skirt of the router motor housing prior to inserting the motor into the router base. By exerting pressure on the upper portion of the spacing attachment, the router operator may continuously vary the depth of cut of the router as cutting proceeds.
