Self-guiding cutters for rounding over edges do not require a side fence. They are supplied with two bearings. Use the larger bearing for a round-over. If the cutter is lowered, a top quirk can be produced. A full round/bullnose for stair treads can also be produced by taking a second pass from the opposite side of the workpce.
