ABSTRACT:
An improved miter gauge includes a gauge body and a lead arm pivotally coupled together. The lead arm is provided by a substantially rigid member which includes a plurality of slots formed in a length direction of the member which define adjoining side wall portions of the rigid member. A plurality of threaded bores are provided, each through one of the side wall portions, in communciation with one of the slots. A plurality of set screws are provided in the threaded bores and are adjustable to project out of the rigid member or to span the slot and contact the opposing side wall portions of the member so that overall width of the rigid member of the miter gauge can be adjusted to fit the width of a guiding slot on a piece of power equipment.
