First time posting, thanks for any help. I bought a ridged R29303 routher with R2901 Moto, R2911 fixed base and R29202 plunge base. I want to mount this on my bench. I'm new to the router game, I assume the fixed base R2911 is the best one to use but what should I do to it, buy a insert plate? make my own? Does anyone know the hole spacing seem like something that should be on the operators manual but it is not. Thanks again!
