A trommel to process charcoal for vehicle use

This is my trommel to separate charcoal from ash, and to crush it finer so it performs better in a gasification unit on my vehicle or tractor. More info about my alternative energy projects here:

It runs on a small AC gearmotor. The cabinet, which amazingly fits the 5-gallon pail trommel screen design, is from a RainSoft(tm) Apollo II water softener.
