Circle cutting is easy with a router and a shop-built trammel. And the trammel doesn't have to be anything fancy. In fact, on the rare occasion that I need to cut circles, I just use a scrap piece of hardboard. Then when the project is complete, the hardboard goes back into my scrap bin.
You can probably figure out how to make one just from the photo, but complete instructions are here (still easy).

Being a woodworker is being part of something much bigger than just a guy in a shop. There's a world of woodworking design, art, and culture. I think that's as interesting as the working with wood itself.
