This is probably the poor mans Vibratory tumbling machine. Old tyres, old water heating bowl tank, an old motor seating onthe selves, some old car’s top mounts from the suspension, and some other scrap metals, and voila, prety good for zero expenses I would say! Update: thank you, unforunately the motor didnt last much time. so then I bought a vibrator motor for 150 euro and modified the motor mount and the bowl mounting and as you can see on the new video it really rocks the parts up! www.youtube.com but it still is a way for a cheap vibrtor tumbling system.
