Thanks Jim and Pat.
Pat, it sounds like getting the angle right for the kerf would be challenging, but it really only takes a couple tries with scrap, i.e., less than 5 minutes at the start of a project. But some warm up is definitely worth it. One hazard is cutting the wrong direction around a piece (i.e., clockwise instead of counter clockwise), which results in a piece that is too big or small for the opening...
