I had some circles to cut out of plywood so I built a sled with out a fence for my new tablesaw. the backgroundnoise in the video is bad because of the saw, and the dust collection going. What I was saying in the video was take light cuts while spinning the circle piece into the blade than advace the sled, and spin the piece again until no more material is being removed, than the piece is completed. I like the router for large circles, but for smaller circles I like the tablesaw the circles are accurate, and the finish is smooth.
Hope you enjoy the video.
