Good article, but there's one thing I just don't get. He describes how to cut planks with an angle on each edge by tilting your stripper, making a cut, then "swiveling the balsa sheet 180 degrees and cutting off the other side. I just don't see how it's possible to get the shape he describes as "A" using this method. Seems to me you would get a "C" shaped piece off each time you made a cut.
Obviously I'm reading this wrong, could someone set me straight?
