Abstract
This invention provides a quick and accurate gauging means for locating and clamping a guide onto the top surface and leading edge of a workpiece, with respect to the line of cut desired. During execution of the cut, the gauging member of the guide is automatically returned to its storage position and cocked for the next cut. This guide is completely operable with only one hand, leaving the other hand simultaneously free for holding and operating the portable hand power saw. This invention yields cuts that are accurate and more quickly executed than freehand cuts or cuts where other types of saw guides are employed.
