Shopguy, there ae different base plates available and some will have the guide bushing holes while others do not. One important consideration is the size of guide bushings you will be using. The most common is the Porter Cable style which locks in place with a knurled nut. The Router Workshop style attaches the same way but lets you use larger bushings. (Router Workshop tools are developed as a system) These are not interchangeable. Other brands attach using screws or in the case of Bosch a special quick release device which also accepts PC style bushings by way of an adaptor plate. If you plan on using your router with female templates in the method taught by Template Tom you will want the larger guide bushings. Some days there are no easy answers.
