Abstract
A mortise and dowel hole jig for ensuring timely and consistent cuts with a plunge router. The jig mounts to a work table and includes slot(s) to confine the router bit while cutting horizontally and holding the router in place vertically by two router guides. The jig also includes a rear clamp to lock-in-place and serve as a face for one or more pieces of wood; front clamp(s) to secure each piece of wood while making cuts; and a centering tool that enables a woodworker to quickly line up the center point of the piece of wood and determine where to make the desired cut.
