Garden knowledge: Making your own compost bin Making compost.

There are many advantages to having your own compost bin in the garden. A particularly sustainable option is this DIY version made from wood. In this video, we show you how to build and set up your own compost bin.

Step 1 3

Measuring and cutting the boards

A wooden plank is being cut to size using a jigsaw.
After cutting the boards, double check to make sure they are all the same size.

You need: Multi-sander, Jigsaw blade T 101 B, 80 to 120-grain sanding sheet, Jigsaws, pencil, pocket rule, Planches en bois

It’s easy to build a compost bin. All you need are several long, wooden boards of the same size. Of course, you can purchase cut boards from your hardware store.
However, if you wish to cut the boards to size yourself, begin by measuring out the correct length and marking the boards accordingly. The longer the boards, the larger your compost bin will be. We recommend that you plan the location of your compost bin before beginning the project.

Once you have measured all the boards, you can begin cutting them to size using a jigsaw. It may be necessary to sand down the cut edges afterwards.

Step 2 3

Cutting the lap joints

A specialised plunge cut saw blade for a multi-function tool is being used to cut a notch in a wooden board.
The width of the notches will depend on the thickness of the boards.

Once all of the boards are cut, they can simply be fitted together. To ensure a secure fit, you must cut lap joints, or notches, at the top and bottom of the long sides of the boards. Note: The width of the notches will depend on the thickness of your boards. The depth of the notches will determine how far apart the boards will be spaced.

Measure the thickness of the boards, and mark out the width and depth of the notches on each board. Make sure that each of the markings is exactly the same. The boards at the top and bottom of the compost bin only require two notches, both of which will be on the top or bottom side of the board, respectively. We recommend using a multi-function tool with a plunge cut saw blade to cut out the notches.

Step 3 3

Fitting the wood boards together

You need: rubber hammer, Wooden boards with lap joints

Now you can begin to assemble your compost bin one board at a time. To do this, simply fit your wooden boards together using the lap joints that you have cut (image 1). We recommend assembling the compost bin in the same location where you intend to place it.
Start by placing two boards (with notches on the top side only) parallel to one another on the ground. Now, use the lap joints to connect the first two boards to two additional boards. You may want to use a rubber hammer to secure the joints. Now you will have a square frame on the ground in front of you.
Add each additional board step by step – the frame will get taller as you progress (image 2). The top edge of the frame will be made up of two boards with notches on the bottom side only (image 3).
