Harbor Freight / Leegol Duel 3 lb. rock tumbler cheap upgrade...(using mini ball transfer bearing)

Most complaints I see, are from the friction and wear and tear that's put on the motor because of the drums rubbing against the black tabs, and eventually, the metal sides. Instead of building a whole new contraption to install a roller wheel ....try this !!
