Abstract
A mortise and tenon generating system 10 having a removable tenon template 12 that attaches to the work piece. A router 26 utilizing a router bit 18 with a bearing collar 30 is guided so that the bearing collar 30 circumferentially contacts a guide edge 54 on the tenon template 12 and machines the tenon 36 out of the work piece 18. A router jig 16 with a tilting table 100 having a machining opening 118 is provided for supporting the router 26 and receiving the router bit 28. The router jig 16 also includes a clamp assembly 98 with a rotatable guide member 168 for receiving the work piece. The tilting table 100 and rotatable guide member 168 allow the work piece to be oriented at a variety of angles with respect to the router bit 28, for the creation of angled and compound angled tenons and/or mortises.
Claims13
A uniform tenon generation system for use in conjunction with a workpiece, said workpiece having a template plane formed on a surface thereof upon which the tenon is to be formed, said workpiece further having one or more guide holes, in and extending generally perpendicularly to said template plane, and a router for machining the workpiece, comprising:
- at least one tenon template, each said tenon template including a surrounding guide edge disposed generally perpendicularly to said template plane and defining the exterior shape of a desired tenon;
- one or more guide pins extending through said tenon template, each said guide pin being adapted to extend into each said guide hole;
- and
- guide following means for attachment to the router, said guide following means being adapted to follow the surrounding guide edge such that the router machines the tenon during a complete pass of said guide following means around said tenon template.
A uniform tenon generation system for use in conjunction with a workpiece, said workpiece having a template plane formed on a surface thereof upon which the tenon is to be formed, and a router for machining the workpiece, comprising:
- at least one tenon template, each said tenon template including a surrounding guide edge disposed generally perpendicularly to said template plane and defining the exterior shape of a desired tenon;
- adhesive means to secure a said tenon template to said template plane;
- and
- guide following means for attachment to the router, said guide following means being adapted to follow the surrounding guide edge such that the router machines the tenon during a complete pass of said guide following means around said tenon template.
A method for machining a workpiece using a router having a router bit with a bearing collar, comprising the steps of:
- a) forming a machining plane on the workpiece;
- b) providing a template having a vertically disposed guide edge and at least one vertically disposed guide pin;
- c) drilling one hole corresponding to each said guide pin, said hole being arrayed to be generally perpendicular to the plane on the workpiece;
- d) inserting said guide pins into the ones of said holes corresponding to said guide pins;
- and
- e) machining the workpiece with the router by guiding the router bit such that the bearing collar circumferentially contacts said template guide edge.
