Milling Machine Made Entirely From Lego

OK, almost entirely: The actual cutting is done by a metal drill bit. Everything else, however, is Lego system elements. It looks like the machine uses a “raster” type subtractive process, covering the surface of a florist’s foam block in a close-packed grid of holes, each of which is drilled to an appropriate depth to form the final surface contours. It doesn’t look like it works at all, until maker Arthur Sacek turns on the hair drier to blow away the chaff. Then the magic happens. [via The Brothers Brick]
