Anyone use two routers, one with the dovetail bit and another with the straight bit, for making through dovetails on a Leigh jig? I'm using a Super 12 not the D4R. The manual recommends not using two different routers because tolerances between the components (router concentricity, template guide bushing, etc) can lead to ill-fitting joints. It just seems so convenient to set up two different routers for the task.
