This simple and straightforward jig lets you make strong and attractive through dovetails using any 1/2" router. The double-sided jig has pin templates on one side and tail templates on the other. The joints can be fine-tuned for a snug fit with the supplied eccentric guide bushing, and their positioning can be adjusted with cams mounted on the jig. You can use the jig on a router table, or operate the router freehand, guiding it manually along the template affixed to a stationary workpiece.
