Abstract
A guide for guiding a power tool such as a circular saw has a planar deck, and two shoulders extending from opposed edges of the deck in diametrically opposite directions. The deck is provided with mounting fasteners for securely attaching the saw to the guide. There is an aperture in the deck for receiving the circular saw, the aperture being off center. By attaching the power tool to opposite sides of the guide it is possible to obtain straight cuts of different widths.
Claims18
A guide for guiding a portable power saw along a workpiece to be cut during the sawing thereof, the workpiece having a surface to be cut and an edge surface, the saw having a blade and a baseplate, the baseplate having at least two mounting holes therein, the guide comprising:
- a) a planar deck having a longitudinal axis and opposed edges on opposite sides of the longitudinal axis and substantially parallel to the longitudinal axis, the deck being adapted to contact the workpiece surface to be cut;
- b) first and second flat shoulders extending from the opposed edges of the deck in diametrically opposite directions, each shoulder being in a respective plane that is substantially perpendicular to the plane of the deck, each shoulder having an inner face which provides a blade guide adapted to provide a predetermined line of cut and to guide the blade therealong, each inner face being adapted to contact the edge surface of the workpiece;
- c) a slot in the planar deck sized so that the blade extends therethrough for cutting when the saw baseplate is on the planar deck, the slot being closer to the first shoulder than the second shoulder;
- d) mounting fasteners for securely attaching the guide to the planar deck;
- and
- e) a plurality of mounting openings in the planar deck for receiving the mounting fasteners, the openings being sized and positioned to provide at least first and second cutting positions,
- wherein for each cutting position at least two baseplate mounting holes are aligned with corresponding mounting holes for receiving the mounting fasteners to securely attach the saw to the guide, and
- wherein in the first cutting position there is a first cutting distance between the blade and the inner face of the first shoulder and in the second cutting position there is a second cutting distance between the blade and the inner face of the second shoulder, the first and second distances being different, so that by flipping the guide over there is provided different pre-determined cutting distances for the saw.
An article for guiding a power tool having a working element along a workpiece having an edge, the article comprising:
- a) a planar deck having a longitudinal axis and opposed edges on opposite sides of the longitudinal axis and substantially parallel to the longitudinal axis;
- b) first and second shoulders extending from the opposed edges of the deck in diametrically opposite directions, the shoulder being adapted for sliding movement between the edge of the workpiece and the article during the working on the workpiece by the power tool;
- c) an aperture in the planar deck for receiving the working element, the aperture being closer to the first shoulder than the second shoulder;
- d) mounting fasteners for securely attaching the guide to the power tool;
- and
- e) a plurality of mounting openings in the planar deck for receiving the mounting fasteners for attachment of the power tool thereto with the working element extending through the aperture, the opening being sized and positioned to provide at least first and second different working positions changeable by changing the shoulder in contact with the workpiece for positioning the working element at different distances from the edge of the workpiece.
