Abstract: The present invention is a simple, inexpensive and lightweight straight-cut saw guide comprising a rigid structural guide member with a number of holes along its axis, a screw driven holding clamp which is attached at one end of the guide member and provides an abutment for engaging one end of the work piece, and a stop clamp with an abutment for engaging the other end of the work piece. The stop clamp is inserted through any one of the holes in the guide member at varying distances from the holding clamp depending upon the size of the work piece to be held and cut. The screw driven holding clamp serves to clamp the saw guide onto the work piece after the abutment is in place.
