That's a great idea!! You just gave me another one ! Turn the whole thing around , use rollers where those black rubber looking things are, set your bucket on top (with that or another classifier inside the bucket) and you have an Awesome bucket trommel that you can turn by hand ! The inner classifier could protrude out a few inches from the bucket so the tailings dump out past the sluice and the classified material fill fall from the lip of the bucket into the sluice.
