Replacement e10 Elliptical Guide Bushing for Leigh RTJ400, B975 and F3, F24 and F18 Box/Finger Joint Templates.
All Leigh Dovetail & Box Joint Jigs require a router with a 1/2″ collet fitted with a Leigh Guide Bushing. To determine if your guide bushing fits directly to your router, measure the opening in the bottom of your router. The widest part, or counter bore, of the opening must be 1-3/8″ and the inner hole must be 1-3/16″. If the opening matches these dimensions, you do not need an adaptor.
