Hi JE Bishop, glad your having fun with your router! I would just go to the links shown and you will see some basic and more sophisticated fences. A good easy to use fence that is made for straight up routing is the Oak Park phenolic fences. Just clamp them down nothing fancy but they do the job. I bought one for my mini table and I have a Bench Dog Pro Fence on my big table. A fence can be as simple as a board or as complicated as you want.

Hope this helps.
