I have come across some machines that can cut silhouettes from card stock and thin wood, like balsa and basswood. These machines go by the names of "Cameo, Curio and Cricut". They are used by those who make craft objects, like scrapbooking, greeting cards, etc. I wonder if these machines could be used for cutting out railroad car sides, details, passenger car sides, houses and structures. The car side could be drawn using CAD software and cut out on one of these machines. Basically these machines are computer printers, but instead of printing on paper, a blade replaces the print head. Has anyone had any experience with these machines?
