Abstract
Abstract A guide apparatus suitable for use as straight edge and a guide for portable power and hand saws. The guide includes a receiver or holder, preferably approximating in length the length of the piece to be worked. A replaceable guide member adapted to be snap-fitted into the holder, preferably fabricated of an expendable material such as plastic, is also provided. When first put into use the replaceable guide member is cut along its saw blade edge so as to precisely fit it to the blade-shoe configuration of the specific power saw with which the apparatus is to be used. In a preferred embodiment the saw shoe and guide apparatus are each modified to provide a guide track configuration at the side of the shoe remote from the blade. Anchoring and clamping devices adapted to engage the holder along its length or at its ends for securing the apparatus in position on the piece to be worked are also included.
