Abstract
A dado indexing jig includes a plurality of indexing members and indexing surfaces that are adjustable relative to one another and a cutting element to account for a width of a workpiece that corresponds to the width of a dado to be cut. In addition, the indexing surfaces are adjustable to account for a width of a blade or router to cut a dado.
Claims17
A dado indexing jig comprising;
- a base having a back surface to abut a fence on a woodworking table;
- a first indexing member connected to the base, and the first indexing member has a first side that is parallel to a second side thereof, wherein the first and second sides are both perpendicular to the fence when the base is placed on the woodworking table with the back surface of the base abutting the fence, and the first indexing member has an end with an end surface that is parallel to the back surface of the base;
- a second indexing member connected to the base and adjacent to the first side of the first indexing member, and the second alignment member has an end with an end surface that is parallel to the back surface of the base;
- wherein the end of the first indexing member and the end of the second indexing member are each adjustable to respective positions adjacent to a cutting element of the woodworking table for making a first cut in a workpiece;
- and,
- a third indexing member connected to the base and adjacent to the second side of the first indexing member, and the third indexing member has an end with an end surface that is parallel to the back surface of the base, and the end of the third indexing member is adjustable to a position between a surface of a fence and cutting element for making a second cut in the workpiece, wherein the first cut and second cut define a width of a dado.

A method of cutting a dado in a workpiece, the method comprising
- positioning a jig on a woodworking table with a cutting element the jig has a first indexing member, a second indexing member and a third indexing member, and a back surface of the jig abutting a fence of the woodworking table;
- positioning an end of the first indexing member against a first side of a cutting element that faces the fence;
- positioning an end of the second indexing member adjacent to a second side of the cutting element that faces away from the fence to account for a thickness of the cutting element for making a first cut in the workpiece;
- and,
- positioning an end of the third indexing member between the fence and cutting element and relative to the end of second indexing member to account for a location of a second cut in the workpiece relative to the first cut, wherein the first cut and the second cut define a width of the dado.
