How to Build a Rotary Compost Tumbler

Fresh organic compost helps your garden produce more healthy vegetables while maintaining an earth-friendly, organic lifestyle. Using a rotary compost tumbler that you build yourself can provide this compost while saving materials and kitchen scraps from the landfills. Follow the simple directions to build a rotary compost tumbler that will turn yard waste and kitchen scraps into rich, nourishing soil for your plants.

Rotary Compost Tumbler - Materials Needed

This do-it-yourself compost tumbler requires a large plastic barrel or drum, a galvanized metal fence post, some 2 by 4 inch lumber and screws. You will need an electric drill with a large drill bit and an electric saw as well. Dark-colored spray paint, such as black or dark green, is optional but can help your compost barrel work more efficiently since dark colors absorb heat from the sun.

Rotary Compost Tumbler - Build It

Cut four pieces of 2 by 4 inch board approximately four feet long and nail them together a bit higher than the center to form X shapes. These are the side supports of the rotary compost tumbler stand that will support the barrel. Measure the length of the plastic barrel you will use and cut four more pieces of 2 by 4 inch board at least eight inches longer than it. Nail these board between the two X-shapes at the bottom and directly under the point where they cross. This gives stability to the structure.

Drill a hole in the center of each end of the compost barrel large enough to pass the metal pole through. Drill smaller holes randomly across the entire barrel. These will provide drainage and air flow for the compost to decompose more effectively. Also drill a hole cross-ways in the end of the metal pole and insert a piece of metal rod or even a strong dowel through the hole. This will make it easier to turn the compost barrel.

Also cut a large rectangular hole in the side of the barrel for a door to put the yard waste and scraps inside. Use hinges and hardware to attach the rectangle back to the barrel and include a clasp on the opposite side that will hold it closed securely.

Rotary Compost Tumbler - Set Up and Use

Position the wooden stand of the rotary compost tumbler where you want it in your yard. The position should get sun but be out of the way of foot traffic and play space. Set the barrel and metal post aparatus into the stand. If desired, paint the entire structure a dark color to aid in heat absorption.

To use the rotary compost tumbler, simply put organic yard waste and vegetable and fruit kitchen scraps into the barrel, add water, and tumble once a day until it turns into compost. Be sure to keep the mixture wet and tumble frequently to prevent excessive heat build up. Your garden will thank you for this nutrient-rich, organic addition.
