Hi Mike, that's not what I asked, I asked, if it needs to be so thin, why cut a 10mm piece and cut it again to 2 to 4 mm, why not start with a piece that thin to begin with? NAU recommends a thin section maker and they want the piece 27 x 46 mm rectangular and 10mm thick, I see no reason to waste 3/4's of it. Thanks, Tom peregrineflier <><
