Power tool guide-clamp assembly

A tool for enabling the cutting of an exceptionally straight line on a wooden board or the like to be used with a table cutter of a type having a flat table-surface on which a board to be cut rests, a cutting element positioned at said table-surface for cutting said board resting on said table-surface and a straight, vertically upwardly extending, table-surface guide at a position on said table-surface offset from said cutting element against which a first edge of said board is slid while said board is being cut, said tool comprising:

• an elongated guide clamp for clamping onto a first edge portion of a board to be cut, said guide clamp having an elongated straight edge extending parallel with the location of said cut to be made to be slid along said table-surface guide, said guide clamp being channel-shaped to receive said first edge of said board to be cut with a portion of said guide clamp extending above said board and a portion extending below said board, said guide clamp including clamping member means for clamping said board in said channel, the portion of said guide clamp extending below said board being flat and smooth on its bottom surface and having a certain thickness for resting on said table-surface to thereby support the first edge of said board to be cut a certain distance above said table surface, said elongated straight edge being positioned laterally beyond said first edge of said board so that said board can be slid across the surface of said table-surface to bring said straight edge into contact with said vertically-upwardly extending table-surface guide and slid across said table with said straight edge in contact with said table-surface guide so as to move said board parallel to said table-surface guide;
• and,
• a separate shim means also having said certain thickness to be positioned independently from said guide clamp laterally intermediate said table-surface guide and said cutting element, between the table-surface and the bottom of said board, at a second, opposite, board edge portion to support the opposite edge portion of said board said certain distance above the table-surface to thereby hold said board level as it is being slid across the table-surface for cutting by said cutting element.
