[QUOTE="Tathradj, post: 160405, member: 2436"] Generally the trommel runs on 4 wheels set at an angle so the drum falls into it. Then there is a flange set parallel to it with a thrust wheel that stops it from sliding down. A belt would be a bit fiddly as it would pull to one side. You could mount it underneath but it would get a lot of water and debris over it. A small motor and light chain is more ideal because it does not require much tension. The bigger commercial units have a gear drive. 3 20 litre drums that stack on top of each other would be a simple way of constructing a barrell but you would have to work out a gear drive for it. A piece of storm water pipe that fits through the bell crank drive sprocket off a push bike is fairly large in diameter. All depends on how far you want to go I guess. [/QUOTE]
