I've decided to mount some scrollsaw projects on elliptical bases with finished edges rather than hang them. The bases are all going to be 1 inch thick, and range between 10 by 4, and 14 by 5 1/2 inches long with a 1/2 inch wide x 1/2 inch deep dado down the topside within which to insert the finished project. Do I freehand the piece around the mounted router, or clamp the base and freehand the router around the edge? My experience with routers is limited to rough carpentry only - no finesse was required. I'd appreciate any suggestions. Thank you, Barry
