There are many plans and designs to choose from, so make sure you take a close look over the rest of the workshop plans featured on our website. Plan everything with attention and adjust the size and the shape of the table to suit your needs. Plumb the legs and make sure the corners are right-angled before inserting the galvanized screws into place. Drill pilot or pocket holes to prevent the wood from splitting.

Building a compost bin

Building the base of the compost bin

The first step of the project is to build the base for the worm compost bins. As you can easily notice in the free plans, we recommend you to attach the 3/4″ plywood base to the 4×4 wooden legs. Cut the components at the right size and lock them together as in the diagram.

Drill pilot holes through the plywood and insert several 2 1/2″ screws into the wooden legs. Leave no gaps between the components and add glue to the joints.

Attaching the bottom trims

The next step of the woodworking project is to attach the 1×2 trims to the base of the worm compost. Align the trims with attention, making sure they are flush with the edges and insert 1 1/4″ screws into the base. Add glue to enhance the bond of the joints.

Building the frame of the units

The next step of the woodworking project is to build the frame of the worm compost bin from 1×6 lumber. As you can easily notice in the image, we recommend you to cut the components to the dimensions described in the article.

Drill pocket holes at both ends of the red components and secure them to the perpendicular components. Make sure the corners are right-angled and insert 1 1/4″ screws to enhance the bond of the joints.

Fitting the slats

Now, it is time to build the bottom of the compost bins. In order to get a professional result, we recommend you to adjust the length of the 1×3 trims as described in the image.

If you want to get a professional result, we recommend you to lock the frame using pocket screws, before fitting it to the main unit. Smooth the edges with sandpaper and don’t leave any gaps between the components.

Fitting the mesh supports

Next, attach the second frame to the bottom of the main units. Build this frame out of 1×2 lumber and lock the components together tightly before fitting them to the main unit. Work with attention and leave no gaps between the components. Align everything with attention and insert the screws after drilling pilot holes, to prevent the wood from splitting.

Fitting the mesh

Afterwards, attach the mesh to the second frame and staple it into place properly. It is essential to remove the excess and to make sure the mesh is secured into place tightly.

Fitting the top trims

Next, turn the main units upside-down and attach the 1×2 trims to the edges, as described in the diagram. Leave no gaps between the trims and lock them together with pocket screws before attaching them to the frame.

Building the top

Building the top for the worm compost bin is one of the last steps of the woodworking project. Build the top out of 3/4″ plywood and attach two 1×2 supports to it, as described in the diagram. Make sure you align the components with attention and lock them together tightly. Build as many main units as you want, before assembling the bin.

One of the last steps of the woodworking project is to take care of the finishing touches. Therefore, fill the pilot holes with wood putty and smooth the surface with 120-grit sandpaper.

Top Tip: If you want to enhance the look of the woodworking project and to protect the table from decay, we recommend you to cover the components with paint (make sure the pain is toxin-free). Place the bin in a proper location.
