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.
