Magnetic gatekeepers nab metal fly-bys  

While spending the better part of an hour sifting through the contents of my dust separator, looking for a screw that had been accidentally sucked up, I came up with this quick ductwork modification that would save me from having to do so again. By epoxying rare-earth magnets on the separator lid's intake tube, all incoming metal pieces get caught and held in an easily accessible spot.
