The bullroarer is an ancient musical instrument used in rituals and to communicate over long distances. It is believed to date back to the Paleolithic period and has been found in Europe, Asia, Africa, the Americas, and Australia. In this article, we will explore the history and cultural significance of the bullroarer in Australia and provide a step-by-step guide on how to make your own Australian bullroarer. Making an Australian bullroarer typically involves using materials such as cedar wood, jute twine, and beeswax, and shaping the wood into a thin rectangular slat that can be attached to a long cord.

What You'll Learn
Choosing the wood
The wood used for an Australian bullroarer is typically a rectangular thin slat of wood, about 15 to 60 centimetres (6 to 20 inches) long and 1.2 to 5 centimetres (0.5 to 2 inches) wide. The wood should be trimmed down to a sharp edge, and you can choose to add serrations along the length of the wooden slat, depending on your cultural traditions.
Cedar is a popular choice for bullroarers because it is lightweight, plentiful, and beautiful. However, any type of wood will work, and you can use whatever is available to you. If you are using a log, you will need to split it to get a reasonably sized piece. Saw to a depth of approximately half an inch, with the desired length of the finished bullroarer plus some extra for wiggle room. For example, if your desired length is 10.5 inches, your saw cut should be at 11.5 inches.
The shape of the bullroarer is important, as it needs to be able to rotate and create sound. It should not be too wide or heavy, or it will not rotate properly. The design of the bullroarer is mostly a matter of taste, and you can experiment with different shapes and sizes to find what works best for you.
Once you have cut and shaped your wood, you can finish it with a coating of beeswax or any other type of finish you prefer. You can also decorate your bullroarer with stains, carvings, pyrography, or paintings.

Shaping the wood
To shape the wood for an Australian bullroarer, start by selecting a suitable piece of wood. Traditionally, a rectangular thin slat of wood, approximately 15 to 60 centimetres long and 1.2 to 5 centimetres wide, is used. Cedar is a popular choice due to its availability and aesthetic qualities, but any type of wood will work.
Once you have selected your wood, use a hatchet and mallet to split the wood to the desired length, allowing for some extra room to work with. The finished length of your bullroarer can vary based on personal preference, typically falling within the 15 to 60-centimetre range.
Next, use a drawknife for rough shaping. This tool will help you create the rectangular shape and refine the dimensions of your bullroarer. Work carefully, ensuring the wood is not too wide or heavy, as this will impact its functionality.
For more detailed shaping and to achieve a sharp edge, use a pocketknife. This is where you can fine-tune the design and add any desired serrations along the length of the wood. The serrations are optional and depend on cultural traditions, so you can choose to include them or keep the design simple.
Finally, use a drill and bit to create a hole at one end of the wood for the string. This hole should be large enough to accommodate your chosen string, typically about 5 feet in length. Experiment with different string lengths to find the most comfortable setup for swinging your bullroarer.
Remember, the design of your bullroarer is a matter of personal taste, and you can further customise it with cosmetic touches like staining, carving, pyrography, or painting.

Drilling the hole
To create the bullroarer, you will need a piece of wood, typically cedar, a drill, and a bit for making the string hole. The wood should be split into a rectangular thin slat, measuring approximately 15 to 60 centimetres in length and 1.2 to 5 centimetres in width. The edges of the wood are usually trimmed down to a sharp edge, and serrations may be added along the length, depending on cultural traditions.
Once you have prepared the wood to the desired shape and size, it's time to drill the hole. Mark the centre point of one of the narrow ends of the wooden slat. This is where the drill bit will enter. Ensure the drill bit is slightly larger than the thickness of your chosen string or twine. You don't want the hole to be too big, as it may weaken the structure, but it needs to be big enough to allow the string to move freely.
Hold the drill firmly and perpendicular to the wood. Start drilling slowly and with gentle pressure to create a smooth and precise hole. Take your time and avoid forcing the drill, as the wood should be soft enough to cut through without too much pressure. Go slowly and steadily until the drill bit emerges from the other side, creating a clean hole.
Now you have a basic bullroarer ready for stringing. The next step is to add the string and experiment with its length to find the most comfortable and acoustically pleasing configuration.

Adding a finish
Now that you've crafted your bullroarer, it's time to add a finish. The type of finish you choose is a matter of personal preference, and you can use anything from beeswax to paint. If you're using a finish like paint or stain that needs to be applied to the wood, it's a good idea to sand your bullroarer first. This will ensure that the finish adheres properly and creates a smooth, even surface.
If you're using beeswax, melt the wax and apply it to the wood with a brush or cloth. You can also use a hair dryer to heat the wood before applying the wax, which will help it absorb into the wood. This will give your bullroarer a natural, rustic look and help protect the wood. You could also use a finish like linseed oil, which will need to be applied with a cloth and left to dry.
If you want to get creative, you could try pyrography, which involves burning designs into the wood with a heated tool. This can create unique and intricate patterns that will really make your bullroarer stand out. You could also paint your bullroarer with acrylic or watercolour paints to add colour and design. If you're feeling adventurous, you could even try carving designs into the wood with a knife or other sharp tool.
Don't forget to finish the string as well! You can use any type of string you like, but make sure it's strong and durable. Experiment with different lengths to find what works best for you. A longer string will create a slower, more relaxed spin, while a shorter string will create a faster, more energetic spin. You can also try using different materials for the string, such as jute twine or cotton, to create different sounds and effects.

Stringing the bullroarer
Now that you have your weighted airfoil (a rectangular thin slat of wood), it's time to string your bullroarer. The string you use should be about 5 feet long. You can use jute twine, braided sinew, or any other type of string.
Drill a hole at one end of the weighted airfoil to attach the string. Loop the string through the hole, leaving enough slack to comfortably swing the bullroarer around in a circle over your head. You may want to add a handle to the string to prevent blisters.
The length of the string and the speed at which you spin the bullroarer will affect the sound it makes. By modifying these factors, you can control the modulation of the sound produced, making it possible to code information. The low-frequency component of the sound can travel long distances and can be heard clearly over many miles on a quiet night.
Experiment with different string lengths and spinning speeds to produce a variety of sounds. You can also try using different materials for the weighted airfoil, such as wood, bone, or even cardboard, to see how that affects the sound.
Once you've found the right combination of string length and spinning speed, you can use your Australian bullroarer to make a distinctive roaring sound that can be heard far and wide.

Frequently asked questions
You will need a piece of wood, a saw, a drill, a draw knife, a pocket knife, a finish (like beeswax), and some string.
Cedar is a good option as it is plentiful and beautiful, but any type of wood will work.
The bullroarer should be a rectangular thin slat of wood about 15 to 60 cm long and 1.2 to 5 cm wide. The wood slat should be trimmed down to a sharp edge.
Tie a long piece of string through a hole at one end of the bullroarer. Twist the string a good bit and give it some slack, then spin the bullroarer above your head. The goal is to spin it just fast enough so that its outward momentum keeps it up.
