Microlux, maker of miniature tools, has come out with a filing machine. It won’t help with your taxes, but it’ll take the tedium out of filing metal, resin, plastic, or wood.
Though filing machines are usually heavy dudes, Microlux has made one for the serious hobbyist. The tool works like an inverted jigsaw, but with a file instead of a blade. The machine cuts only on the pull stroke and only on stock up to 3/8″ thick. Just clamp it to the edge of your bench and begin filing.
By attaching a separate transformer, you can adjust the speed between 1,800 and 6,900 strokes per minute. That, combined with the choice between a coarse or fine file, gives you a lot of control over the level of finish and the speed of removal.
The Microlux filing machine is being sold exclusively through Micro-Mark, so there’s no street pricing. Micro-Mark is selling it for $80.
