Grain mill
i think the vibrations would shake the grain into the rollers, but I crush the grain by hand, so a knock to the side every now and again is all i can do.... i will however modify the hopper so it accepts a little more grain at once... and i might even get one of those downpipes so i'm not stoping every 4 minutes to fill the hopper...
