Make your own rotating compost by following this step-by-step guide, and get a rich soil for your garden and pots, achieving optimal growth of plants and vegetables.

Here is what you need to make your own compost bin:

  • Barrel.
  • 3 ″ abs flange for toilet.
  • 3 ″ PVC pipe.
  • 3 ″ PVC cap.
  • 2 pieces of 2 x 6 x 10 pressure-treated lumber
  • 20 screws for pressure treated wood.
  • 2 hinges with corresponding screws.
  • 1 window latch with corresponding screws and nuts.
  • 1 galvanized tube 1 ″ in diameter and approximately 4 feet (approx. 1.20 cms.).
  • 8 1-1 / 2 ″ wood screws.

And these are the tools you will need to complete the project (subject to using your own tools and skills to do so if you don’t have all these tools listed below):

  • Squad.
  • Manual circular saw with wooden blade.
  • 5/16 ″ drill bit, hole saw slightly larger than your galvanized pipe / closet rod.
  • Fine-grit sandpaper.
  • Circular saw.
  • Mosquito net for window.
  • Scissors to cut mosquito nets.
  • Flat head and head screwdriver.
  • Hammer.

Making a rotating compost bin

If you can avoid buying and reusing all these or most of the materials, it is much better, the sense of this work more meets your expectations. Let us begin!

Determine which end is best for your keg and for you. Use the hand saw to cut the lid into a semi-circle shape (half of the entire circle).

This is what the lid will look like when you’re done cutting it.

Pre-drill the holes for the hinges and latch. Attach the hardware, using the bolts and nuts (bolts on the outside, nuts on the inside).

Put the drill bit or bit into your drill and measure halfway down each side of the barrel, starting on each side of the cap. The holes must be drilled so that the tube passes parallel to the cap.

Drill the holes to pass the tube. Insert the tube to make sure the barrel can turn easily. If not, increase the diameter of the hole slightly.

At the bottom of the barrel, trace a 3 ”opening for the toilet flange. Cut out the circle with the hand saw.

Insert the toilet flange to the outside of the barrel and make sure it fits snugly.

Cut the screen enough to cover the bottom of the opening in the flange. Drill holes to screw the flange to the barrel and the screen to the flange.

Take the pipe out of the barrel and place the PVC pipe vertically into the barrel, fitting it over the toilet flange. Cut it to fit vertically inside the barrel, leaving approximately 6 ″ of clearance between the top of the pipe and the opening of the composter. Place the 3 ″ plug on top of the pipe.
Mark on the galvanized pipe where it will meet the PVC pipe.

Using the drill with the 5/16 ”bit, drill several multi-inch holes in the PVC pipe. Using the hole saw, drill two holes in the PVC pipe so that the galvanized pipe can pass through.

Using the same 5/16 “bit, drill vertically aligned holes in the barrel, about 2” apart from each vertically and 6 “horizontally.

Cut two identical “legs” for the composter with your circular saw and the pressure-treated wood. Start by measuring from the side of the barrel towards the center, adding 1 foot to the measurement. For each “leg”, measure 2 ”from the bottom of one end, center the hole to cut a circle for the tube to pass through.

Cut four identical lengths of wood to secure the legs. Secure with the pressure treated wood screws as you can see here.

I have added spacers between the pressure treated wood and the barrel to keep the tube in place. They were just pieces of pvc tubing that fit around the tubing, cut to 2 “long.

Take a spin and see how much fun it is to make your own compost bin.

Start collecting waste from your kitchen: vegetables / fruit and scraps of shells, eggshells, coffee and garden filters, etc (no meat, eggs or dairy products) and throw everything in the barrel with dry leaves, grass and yard waste with a ratio of 1 (kitchen waste) to 2 (yard waste).

Rotate the barrel once a week and keep it as damp as a damp sponge by adding water as needed.

Our rotating compost is ready to be used in the garden, when the compost smells like heavenly earth and is black and crumbly, you can use it for your crops. Your plants will thank you so much for this delicious concoction.
