    A magnetic tumbler.  Unlike your raytech, these use tiny,
    lightweight steel pins.  More like little needles.  No metal removal,
    but a nice semi bright burnished finish in even the tiniest details. 
    Perfect for reticulated surfaces. And unlike brass brushes, it won't
    leave a colored surface residue.  The machines work quickly (fifteen
    minutes to a half hour is quite enough), and because the individual
    pins are so small and light,  there's virtually no surface
    compression to the burnishing action.  Ordinary steel shot will
    press a LOT harder, give you considerable surface compression and
    hardening, and thus tend to remove and obscure fine details.  The
    magnetic tumblers don't do that.
