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.

Claims7

Dependent claims

A jointer for accommodating the cutting of a workpiece with a router comprising:

a positioner member having two generally planar parallel faces and adapted to be mounted vertically when employed with a router, said positioner member having a horizontal upper edge and two generally vertical side edges and having a cutout extending inwardly from said upper edge and having sides thereof spaced from the side edges, respectively;
a generally planar support base member mounted on said upper edge and extending perpendicularly to said positioner member and outwardly from each of said parallel faces thereof, said support member being secured to said positioner member so that when said positioner member is mounted vertically, said support base member extends generally horizontally;
said support base member having an inner cutout therein positioned in alignment with said cutout in said positioner member, means for mounting a removable router template on said support base member so that said template extends across at least a portion of said cutout in said support base member, and
one of said support base member and said positioner member having indexing means thereon for precisely referencing an end of a workpiece relative to said template when said workpiece is secured to said jointer.
