The science of instrument-making | Creators | ABC Australia

Do you think of instrument-making as an old-world craft?
Well, it doesn’t need to be, as Daniel Brauchli’s work goes to show. He’s using science and innovative design to bust the myths that surround instrument construction.

A luthier is someone who builds or repairs string instruments generally consisting of a neck and a soundbox.
The word "luthier" comes from the French word luth, which means lute. A luthier was originally a maker of lutes, but the term now includes makers of stringed instruments such as the violin or guitar.

I have to present myself as an instrument maker or a luthier because I'm making, you know, violins, guitars, mandolins.
Virtually any stringed instrument.
But all of my designs are based on being non-traditional.
There's no reason for me to redo what other people have already done.
The big innovation, which is changing the sound of my instruments,
and makes them very notably different to a standard traditional instrument
is the use of carbon fiber to change where the wood moves, and where it doesn't.
Being able to add strength and stiffness to a piece of wood without adding weight is the key to it.
That's what Formula One cars and all that and helicopters are all about now.
Is using modern materials to create something which performs but doesn't have weight attached to it.
The carbon fiber goes above and below the bracing system,
which is inside the guitar underneath the bridge.
I actually do my bracing and all the fine work when the sides in the top are joined into one pace.
That allows me to really see if it's got enough flex and the places I want and enough stiffness.
So using carbon fiber is a huge part of this because
if I was working with just wood braces, there is a strength to weight ratio,
that can't be changed. It's that's the strength to weight ratio of that wood.
But using synthetics, I can surpass that ratio by 10 to 20 times.
Which means I can do things acoustically which traditionally could never happen.
A lot of traditionalism is mythology.
There's a lot of people say stuff about a guitar.
You know what parts of it should move and what parts shouldn't move.
A lot of it's not true. If you look at real acoustic modeling.
It's about creating parts that don't move.
And that's very important to sound production, is to make parts just supportive structural things
and not part of the sound.
I think being a multi-instrumentalist, and a sound technician and a lot of other things.
Has led me to a place where I want to break a lot of those barriers that are traditional ones.
This is my Lifetime's work,
my bringing together my musicianship with a love of wood
with a love of science and with also wanting to pass on things.
I think what really motivates me is creating something different that will go on to influence other people
and become part of the whole traditional education.

I have always admired Daniel as an original and a genius. At times it was hard having a younger brother who was just so good at everything, but then I realized, "Hey, if we're related, I must be smart too".... God Bless You Daniel...

I love Daniel's Mandolins - the flurocarbon string models look amazing. Nice vid on the process too 👌

[Monkeyboy]

how are there only a thousand views, is no one else interested, it's so fascinating

Look and sound are beautiful. I have taught myself how to make, what I call - "box ukuleles". I really enjoy all parts of the process, especially the working with only hand tools and then the reveal of the sound and playability in the end. I really identify with how you are breaking away from the paradigm.

The x braced design looks very heavy and clumber some, it doesn't look like a feat of well thought out engineering
Falcate and the lattice shown here are two ingenious methods

[weareallbeingwatched]

Yea the bearing edge or the ground- *precisely* - the fulcrum point is the secret
