Welcome Chris. We use guide bushings of different sizes to follow the edge of a pattern. The size of the bushings determines how much offset there is between the pattern and the wood we are cutting. This is similar to using a bit with a bearing on the end as a guide, but gives many more possibilities. If you want to head down I-75 for about an hour I will set you up to try them out. Nothing teaches as well as doing.
