Materials needed to build a tongue drum

Making a metal drum requires specific tools and suitable materials. To complete this project successfully, it is crucial to have the right equipment and choose quality components.

List of tools and materials

Here is a detailed list to help you get started:

• 125 mm angle grinder with Norton discs for precise cutting.
• 800 W drill or more for drilling through metal with ease.
• Korg OT-120 tuner for accurately adjusting the notes.
• Hammerite rust-resistant paint to protect and customize your instrument.

If you use a standard 13 kg gas cylinder, make sure it has been emptied and cleaned before you begin.

Where can you obtain the materials?

To save up to 60%, choose refurbished materials. Here are some useful places to look:

• Specialist recycling centers where you can recover scraps of 2 mm sheet steel.
• Industrial marketplaces where you can find second-hand tools in good condition.

This environmentally friendly approach reduces waste while saving money.

Preparing the gas cylinder

The success of your project largely depends on the initial preparation. This step is crucial to ensuring safety and the quality of the final result. Poor preparation can compromise the entire process.

Emptying the gas cylinder

Before handling it, make sure the gas cylinder is completely empty. Follow an INRS-certified procedure to depressurize it safely. A residual-gas detector, such as the Dräger X-am 2500, is recommended to confirm that no gas remains.

Mickaël Chaput’s professional technique includes rinsing it three times with a degreasing additive. This method removes all residue and prepares the surface for the following steps.

Removing the supports and preparing the surface

Once the cylinder is empty, remove any unnecessary metal supports. Use an angle grinder to cut away the unwanted parts cleanly. This step makes the steel surface easier to access.

To optimize the subsequent tuning, prepare the surface by sandblasting it to 80 microns. This method removes rust and imperfections, providing a solid base for cutting.

“Sandblasting is essential for ensuring an even surface that is ready to be worked.”

Finally, wear suitable personal protective equipment (PPE), such as level 5 cut-resistant gloves and an FFP3 mask. These precautions minimize risks and ensure that you can work safely.

Choosing a cutting pattern

Choosing the cutting pattern is a key step in creating a harmonious instrument. It determines the scale of notes and directly influences the sound of your drum. Take the time to consider this step carefully for the best possible result.

The different available scales

Several scales are commonly used for metal drums. The pentatonic scale, for example, is ideal for beginners because of its simplicity and soothing tones. The diatonic scale offers more musical possibilities, while the chromatic scale provides great versatility.

The Akebono scale, which originated in Japan, is also an interesting option for anyone seeking unique tones. Each scale has its own characteristics and can be selected according to your musical preferences.

How do you choose the right scale?

To choose the scale that suits you, start by defining your goals. If you are a beginner, the C major pentatonic scale is an excellent starting point. For more advanced projects, explore scales such as Akebono or the chromatic scale.

Here is a comparison table of frequencies and their associated emotions:

To calculate the length of the tongues, use the following formula: L = √(E/(ρ*(f/2)^2)). This method allows you to obtain precise, harmonious notes.

Finally, to make your work easier, download PDF templates suitable for standard diameters from Instruments du Monde. These resources will help you make a perfectly tuned drum.

Cutting the tongue drum’s tongues

Cutting the tongues is a crucial step in achieving a harmonious sound. This stage requires special care and maximum precision to ensure the instrument’s quality.

Marking the cuts

Before you begin cutting, it is essential to mark the areas carefully. Use thermal transfer paper to transfer the template onto the metal. This method ensures optimal precision and prevents errors.

Here are a few tips for successful marking:

• Check the template’s alignment before applying it.
• Use a pencil or fine-tipped marker to create clean lines.
• Make sure the measurements correspond exactly to the chosen pattern.

Precise cutting techniques

Cutting the tongues requires suitable tools and a rigorous technique. Mickaël Chaput’s method, which uses CNC-assisted laser cutting, achieves precision of ±0.1 mm. For hobbyists, an angle grinder fitted with a 1 mm disc rotating at 12,000 rpm is an effective solution.

Here are a few tips for successful cutting:

• Choose a V-shaped cut to improve resonance.
• Check the quality using a suitable holographic projection.
• If you make a mistake, use a corrective solution to adjust the tongues.

“Cutting precision is the key to obtaining a perfectly tuned instrument.”

By following these steps, you will create a drum with harmonious, soothing tones.

Tuning the tongue drum

Tuning is an essential step in bringing your instrument to life. Without precise adjustment, the notes will be unbalanced, affecting the sound quality. This stage requires patience and suitable tools to achieve a harmonious result.

Using a tuner

For professional tuning, use an electronic tuner or software such as Audacity with the Gnaural plug-in. These tools analyze the frequency of each note and allow you to adjust the tongues accordingly. Here is a five-step procedure:

• Place the tuner near the drum so it can pick up the sounds.
• Play each note individually and observe the displayed frequency.
• Use N52 neodymium magnets to make fine adjustments.
• Correct unwanted harmonics by slightly changing the length of the tongues.
• Check the result using a spectral analysis in SpectrumView.

Adjusting the tongues to obtain the correct notes

Adjusting the tongues is crucial to obtaining the desired notes. Use a reference table matching thickness and length to frequency to guide your modifications. For example, a shorter tongue will produce a higher note, while a longer tongue will produce a lower sound.

“Precise tuning ensures soothing, balanced tones.”

Finally, test each note after adjustment to make sure it is in tune. A well-tuned instrument offers an incomparable musical experience.

Finishing and customization

Give your drum a soul with carefully applied finishes. This final step transforms a simple object into a unique instrument that reflects your personal style and creativity. Whether you choose a restrained appearance or intricate patterns, the finishing touches add an artistic element to your creation.

Sanding and smoothing

Before adding any decoration, make sure the surface is perfectly smooth. Use fine-grit sandpaper, from 220 to 400 grit, to remove imperfections. This step is essential for applying paint or other finishes evenly.

For a professional result, wipe the surface with a damp microfiber cloth to remove dust residue. A clean surface ensures better adhesion of finishing products.

Painting and decorating

Painting is one of the most common ways to customize your drum. Here is a comparison of the available options:

To create custom patterns, explore acid etching or the nitric-acid metal patina technique. These methods can produce unique, durable designs.

Mickaël Chaput offers an exclusive technique: cold brass inlay. This method adds an elegant, durable touch to your drum.

“Customization is what transforms an instrument into an extension of oneself.”

For optimal protection, especially outdoors, choose a marine-grade anticorrosion treatment. Finally, let your imagination run free with creative ideas such as UV fluorescence or resin inlays. Your drum will become a true work of art and music.
