ABSTRACT:
This invention relates to a jointer which can be accurately positioned and firmly held to the mating members of a workpiece. The jointer, when used in conjunction with a series of removable templates, will properly guide a hand held router utilizing a variety of bits to cut the matching edges of the workpieces. The jointer can be positioned to cut matching joint configurations either across, or parallel to, the edge of the workpiece which when joined form, a variety of completed and matching joints. The joints which can be fabricated include, but are not limited to the following: through-dovetail joints of different configuration sizes, box joints, through-dovetail joints where the board thickness is greater than the bit cutting length, half blind through dovetail joints, in plane dovetail joints, sliding dovetail joints, mortice and tenon. The jointer includes accurate indexing means formed therein cooperating with the templates for precisely defining the relative positions of each segment of the joints to be fabricated in the workpiece.
