Router requirements

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. A plunge router is recommended for Isoloc Templates and is required for the M2 Attachment. When buying a router, also consider ergonomics, switch location, a good plunge mechanism and easy, accurate adjustment of bit height.
 
Router Collets

3/8", 8mm and 1/4" bits require the use of a collet reducer, or a collet that matches the bit size. See video >
 
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 >
