Hi Randy, so one other thing that I'm not quite sure if I understand is if you're sure you want this little kind of ledge left by the cutting object here (the one outlined in yellow):



Do you possibly want something more like this? :





On that example the cutting object has a kind of outward swoop to it so that when it cuts it doesn't leave a little ledge or shelf in there...
