Claims8
Apparatus for guiding a power circular saw across a workpiece and effecting splinterless cutting thereof, comprising:
- (a) a saw guide assembly having a shield member with a bottom surface and a saw guide surface along one side thereof,
- (b) a base member with an upper surface and a lower surface, and fastening means for detachably and adjustably securing the upper surface of said base member to the bottom surface of said shield member whereby a portion of said base member extends normally of said guide surface a distance to a lateral base guide edge, parallel to said guide surface fastening, said base member being of material cutable by said power saw and the distance to the base guide edge being defined by an initial cut to said base member by the power saw when guided by said guide surface, and
- (c) means for mounting said saw guide assembly on the workpiece to be cut, whereby said lower surface and guide edge of said base member are in intimate direct contact with the top surface of the workpiece, the base edge delineating the line of the intended kerf to be made by the power saw.
A saw guide assembly for guiding a portable power saw having a circular blade across a workpiece to be cut comprising:
- a shield member having a guide surface to guide the baseplace of the saw so that the blade will follow a predetermined line of cut,
- a base member having upper and lower surfaces and being of a material cutable by the saw blade to provide a guide edge,
- fastening means for securing said members, with the upper surface of the base member contiguous with the shield member and said guide edge distant from and parallel to said guide surface on the shield member,
- the extended portion of the upper surface between the guide surface and the guide edge accommodating the baseplate of the saw with the guide edge abutting the saw blade,
- said assembly being adapted for mounting on the workpiece with the lower surface and guide edge of the base member in close surface contact with the workpiece and with the guide edge aligned with the predetermined line of cut for accurate and splinterless cutting to the workpiece.
