We picked up some cheap untreated 8′ 1×4″s and a can of butcher block oil and made an all natural compost bin. We didn’t want chemicals from treated lumber leeching into compost. The oil goes on easily with a rag and provides a food safe barrier for the untreated wood. With the help of an air compressor and nail gun this project went together pretty quickly. Peace of mind and the bonus of using pneumatic equipment is always good for the soul.
