Make a compost tumbler




compost1Here’s how to tumble your way to rich compost for your garden and plants.

WHAT YOU’LL NEED

  • Sturdy plastic 55-gallon (or so) food barrel
  • Drill
  • Saw
  • Hammer
  • Adjustable wrench
  • 8 3⁄8-by-3 1⁄2-inch carriage bolts
  • 8 3⁄8-inch nuts
  • 8 3⁄8-inch washers
  • 16d galvanized nails
  • 2 bungee cords (If barrel has a locking lid, you won’t need the bungees.)
  • 5 2-by-6-inch boards (Lengths will be determined by the size of the container.)
  • 3⁄4-inch galvanized pipe, threaded both ends (You can get a standard-size pre-cut threaded pipe. The length will be determined by diameter of the barrel.)
  • 2 3⁄4-inch galvanized pipe caps

WHAT YOU’LL DO

Prepare the Barrel

1. Wash out the barrel and drill two 7⁄8-inch holes halfway between the top and bottom. These holes are for the 3⁄4-inch galvanized pipe.

2. Drill 1⁄2-inch holes evenly spaced around the barrel.

Build a Sturdy Frame

3. Cut the 2-by-6-inch boards and assemble the frame as shown, using the hardware listed. The feet should be almost as long as the legs are high.

5. If the lid needs to be held in place, drill small holes around the lid to hook bungee cords.

COMPOSTING BASICS

Layer yard waste into the tumbler. Alternate green materials like grass clippings with brown ones like hay or fallen leaves. Put in some garden soil and kitchen waste such as veggie scraps, fruit peels, cereal, bread, crushed egg shells, tea bags, and coffee grounds and filters. Never use meat, poultry, fish, dairy or pet waste. That stuff can attract unwanted critters.

Bacteria breaks down the materials in your tumbler and turns it into rich organic compost. The decomposing material will become hot as the bacteria does its work. The material in your tumbler should be about as moist as a damp sponge. Spin your tumbler one or two times a week to mix the contents and keep it aerated.

HOW TO FIND A BARREL

Food barrels are used for things like juice or pickles. Try checking with large restaurants or food distributors. Also, there are companies that sell used food barrels.

    my dad and I built a composter and it works great!

  2. Compost Wantabee says:

    How long does it take for the compost to breakdown and is there a way to separate the newly added scraps, etc from the already broken down compost that is use-able?

  3. Degreaser says:

    The compost tumbler that boys life put on pintrest works great.I made one this
    weekend i had all the material except for the pipe and the two end caps that cost me 11.89 + tax not bad. Great idea.
    Thanks Degreaser

  4. Vida says:

    I live in the mountains. I would really like to build a compost tumbler but I am wondering if I have to put so many aeration holes in the tumbler. I don’t want the bears, lions, variuos creatures to smell it. Any advice? Thank you.

    • honeybear says:

      If you don’t want critters in your compost, don’t compost cooked food,{such as meats, anything with butter on it, ect}, only compost raw vegetable scraps, paper, yard waste, coffee grounds, eggshells.. .. you get the picture.

  5. steve says:

    I dont think there is anyway that a bungee cord is going to keep the lid on when its upside down cause those cords stretch

  6. softstep says:

  9. tom says:

  10. Frenchy says:

    How often do you turn it? Daily? How long for chicken, horse or goat compost is ready? Any Recipes for it?

    Thanks

      The tutorial states that you should turn it 1-2 times per week. I’m not sure what you mean by “chicken, horse or goat compost”, but again, it clearly stated that you should NOT PUT ANIMAL WASTE into the compost. Hope this helps and is not too late!

      • lkmbiker says:

        Actually, it doesn’t say not to use animal waste. It specifies “pet” waste/ This is because dog and cat waste can contain pathogens harmful to humans. Composting cow, goat, sheep, horse, chicken, etc actually improves the output.

      • zoonoticvet says:

        Actually all animals (goats, dogs, cats, cow, horses, etc) can potentially carry parasites that can be harmful to humans; especially if proper deworming protocols are not used.
