Which often makes me wonder why guys aren't CNC machining the moulds rather. You'd have a simple CNC mill where the tool sticks directly upwards, and use a dremel as a spindle. Now you just 'machine' away the green sand until done. You machine the cope and the drag in a similar way, including registration features.
