Step 1: Create A Compost Tumbler Lid 

To create the compost lid, you’ll need to mark out a rectangle. Carefully measure 11 inches across and 10 inches wide. You will be cutting the sides and front of the lid, but leaving the back of the lid attached to the compost bin for now.

Step 2: Cut The Compost Lid  

Start with the angle grinder and carefully cut through the compost bin, following the lines you’ve just marked out for the lid. If the angle grinder starts to burn the plastic, switch to a wood hacksaw and manually cut the lid. It’s a good idea to stand over the compost bin to ensure you have a steady grip on the saw. Take your time, there is no need to rush.

Step 3: Mark Out The Hinges  

So you can easily lift and close the compost tumbler lid, it’s time to add two hinges. First, measure 2 inches from each side of the lid, and place the hinges on the back of the lid, as shown above. Using a marker, make a note of where the holes will be. Now you can cut out the whole lid and remove it from the bin.

Step 4: Add The Hinges  

Now use the drill to cut four holes in the lid, where the hinges will go, and four in the compost bin where the lid will be securely attached. Add the hinges to the lid using bolts.  Sand down any rough edges of the lid and inside the cut out part of the compost bin. Now make sure the lid is tightly attached to the compost bin.

Step 5: Add The Barrel Bolts  

It’s important to make sure that the barrel bolts are aligned correctly. One part will attach to either side of the front of the lid, and the other two will be secured on the compost bin, allowing you to lock it in place. If they’re not aligned well, you’re not going to be able to shut the lid. Any gaps with cause spillage when you spin the compost tumbler. Again using a marker, mark out where the barrel bolts will need to go on the lid and on the compost bin and then double-check your measurements are accurate. When you’re happy, start drilling the holes and attach the bolts.  

Step 6: Measure & Cut Wood Mount  

Measure 35 inches in length, for both the 2 by 10 wood panels, which is the height of the 55-gallon compost drum. Using the wood hacksaw, cut the wood to the right size.  For the 2 by 4s, mark 18.5 inches in length and cut using the hacksaw. This measurement is the full length of the 2 by 10s, put together, as shown in the below. 

Step 7: Adding The Wheels 

Measure 4 inches on both ends of the 2 by 10s, and this is where you’re going to attach the wheels that will help your compost tumbler to turn and rotate freely. Check the image above for reference. This will mean your wheels will be 13.5  inches apart and evenly spaced out. Mark out three holes in the 2 by 4s, an equal distance apart and screw the pieces of wood together to form the base of your compost tumbler. Now screw the four wheels in place. 

Step 8: Create Airflow Holes 

Mark out several rows of holes above the lid of your compost bin and all the way around, 5 inches apart, as shown above. Carefully drill the holes. This will allow air to flow freely throughout your compost bin, speeding up the process of making your own compost. 

Step 9: Add Compost Mix 

You can often find free compost online, by searching on Facebook Marketplace and Craiglist, or you can ask family, friends, or neighbors. Rabbit hay, rabbit poop, and grass cuttings are a great base for your compost tumbler. After that, you can start adding any leftover food products such as eggshells, coffee grounds, and food waste.
