What about a bike chain?? I'm not quite sure how you would go about attaching it to the base. Where I work they have tumblers to clean the product. What they are is a metal tube with bike chains raped around them on each end. In this case the chains are tack welded to the tube. Then these tubes a sat on top of 4 cogs which turn the tube. Just another idea for you to think about.
