What Router Should I Use?
Leigh recommends a midsize router, from 1-1/2 to 2-1/4 HP (9-13 amps) with a 1/2” collet. This size provides great power to weight ratio. Fixed base routers are ideal because they have a lower center of gravity with handles mounted to the router base rather than the motor, as with plunge routers. However, if you are proficient with the use of a plunge router, it works just as well.
Guide Bushing Adaptors for your Router
All Leigh Dovetail & Box Joint Jigs need a router fitted with a Leigh guide bushing. Because the router industry isn't standardized, you may need an adaptor to fit the guide bushing to your router. Learn more >
The F3/F3M requires a router with a 1/2" collet, and smaller bits require the use of collet reducer. See video >
