This was my first attempt at edge profiling, although I had milled right-angled strips before. I was nervous at first, but got used to it quickly. I've found that I don't need to support the base of the router other than resting on the workpiece. I used carpet tape and attached each piece, leaving enough space around it by simply holding the router with my hand. The cutter pulled the cutter along the edge of the part as if it had a magnet. He just turned the corner, which was wild and surprising. The edges came out clean and tight with virtually no tearing (I just brushed off a few fibers with my fingers). See photo. The beat worked great.
