Mortise and Tenon joinery has been around for a long time; a seriously long time - it's actually ancient history. But, it's always been difficult to ensure that they line up correctly and are sized appropriately.
General Tools has introduced an EZ Pro™ Mortise & Tenon Jig that helps that issue be a thing of the past. It comes assembled ready to use to produce 1/4" mortise and tenon joints. Using a plunge router with the jig, woodworkers can quickly and easily cut fully aligned mortises and tenons ranging from 1/4" to 1/2" thick and from 1" to 3" wide in materials from 1/2" to 1-1/2" thick. The jigs can be mounted on your workbench or can be mounted to a board which is then attached to your workbench and removed for storage if workbench space is at a premium. The jig is manufactured from T6 aircraft aluminum for durability. Thumb screws hold your work piece in place. Sliding templates allow you to adjust the length of the joint and a swing arm centers and aligns your cuts.
The kit includes a wrench for the guide sleeve, a 1/4" up-cut spiral bit, bushing kit, a centering pin and a User's Manual. The jig is 14-1/2" x 3-1/4" x 4" and weighs only 5 lb. Imported.
