Tim, you have serious skill! I've been making model planes and replacement parts for instruments for about ten years. Your ability with carbon is simply astonishing! Keep it up!
Excellent work Tim, thank you for sharing. I truly believe Carbon (and other composites) has a very bright future ahead so please keep us posted on your developments. looking forward to your success!
Amazing. I would love to try out a carbon fibre cello. There is a company in London, Ontario that makes them, but the people at the repair shop I go to, told me that the cellos aren't properly made and there are many issues with them. One day I will visit the shop and check them out for myself. I won't be able to afford one of those, but like the look of them and they come in various colours.
I can't speak about the quality of instruments of other makers. As you can see in the video my instruments are very properly made ;) Always welcome to visit my workshop in Ghent, Belgium to try out some instruments yourself! All the best, Tim
You mean to make a mould (instead of glass fiber) or to make the actual instrument? In case of the actual instrument the stifness to weight ratio of PVC is not that good, making it less ideal for instruments that rely on soundboards.
Just wanted to ask, if the material is now easier to vibrate, does it mean 3/4, 2/4 sizes are much easier to play, and in theory would make a better sound? I know cost is a big issue, but if cost aside? Another thing, now that the material is flexible before treatment, unlike rigid wood, have you tried different shapes, without sharp corners (with round edges instead), which in theory would make vibration much more efficient, essentially like a flattened Gourd shape.
Great videos, Tim! I am curious about the violin with a trapezoid shaped body, visible in back left behind your vacuum table. What is this thing, how did you choose this shape, and how did it turn out? We’re there changes you made to the plates to work better with this different shape?
Hi David, it is a trapezoidal violin made after the instruments and description of Félix Savart (1819). I've published a paper about the modal analysis of the instrument: acoustics.ippt.pan.pl/index.php/aa/article/view/792 He chose this shape in an effort to simplify the production and optimize the sound. He believed that completely flat plates in a simple and symmetrical shape would work better then the classic once with an arching. The bass bar is also not below the bridge foot but rather in the middle of the instrument along the axis. If he succeeded in his quest is a yes and no answer. Obviously, these kind of violins did not replace the 'normal' shape we still use today. On the other hand, he did succeed in making the vibrations in the violin more symmetrical and the violin does sound pretty good. If you like the sound more or less then a conventional instrument is very personal. Personally I was surprised that the sound difference was rather small, I had expected a bigger difference.
@@TimDuerinck great info, thanks! I will read through your paper for sure. I love learning about violin experiments, especially from times past. It is brave to do something so different!! I’m curious, do you make 3D models of your instruments?
@@openfabpdx I made some scans of my violin model in the past. A student from Ghent University used it to make a virtual model for research purposes. But as you see in the video I shape them by hand, so I don't usually work with 3D software.
It's clear how you came up with the shape, but I wonder how you came up with the layup schedule? That seems like it would have been a lot of trial and error. Were you able to come up with something that worked on the first try, or did you have to experiment with different layups? Did you use any calculations or analytical tools, like Finite Element Analysis, in determining the layup pattern/schedule?
Hi, it was calculated based on knowledge of thickness/stiffness of wooden instruments, followed by some trial and error to get it perfect everywhere. A master student of University of Ghent did make a FEA model of my violins to experiment with different materials and thicknesses and their effect on the vibrational modes of the plates. We learned allot from that as well!
This was very interesting. I have a Quintas cf cello and always thought it was the first maker of cf. I love it but I have a problem with not being able to hit the middle of the string at the base of the neck. Is it possible to make adjustments since neck and body look like all one piece?
Hi, for my instruments the body and neck is indeed one piece, I don't know how your cello is made specifically. The distance relation between the position of the middle of the string and the base of your neck is usually made by cellomakers to fit within a standard. A newly made modern cello (carbon or wood) should fall within these standard measurements. It could be that this is not the case for your cello (I don't know the instrument), in that case it's an error from the maker. The shape of the heel of a carbon neck cannot be adjusted, but depending on current string length and the ratio between your neck and body some smaller adjustments could be made that shift the middle of the string more towards where it should be for you. This really depends on how the instrument is made and glued together. If the touch is removable or not,... This I can't say without seeing the instrument. For these smaller adjustments, you can always go to a luthier near you to see what's possible.
I have based them on the dimensions of conventional wooden cello's. The shape stems from these dimensions and is my own design, of course inspired by other luthiers (in particular the cornerless insturments by F. Chanot). If you'd like to know more on how classic bowed instruments are designed I suggest reading the following book: F. Denis (2006). Traité de Lutherie; The Violin and the Art of Measurement.
@@TimDuerinck thanks so much, i'll definitely give It a read. really interesting stuff. whilst I'm here, i am curious, does the air capacity that a cello holds (volume of the cello body) effect the fundamental frequencies, overtones and harmonics of notes at all?
@@jeremywong3318 Yes, definitely. The air volume determines the Helmholtz resonance. It is especially important for the radiation at lower frequencies.
Hi Mika, as you can see in the video it's a bit thicker then the other parts of the soundboard. You can see in the video that it's 6 layers, of which two are unidirectional.
I already make violins from carbon fiber and flax fiber! I just did not make any videos about them. There are pictures and recordings of the violins on my fb and insta page if you are interested! I do have a video here on youtube of a quartet in which the violins played are also made by me.
Hi Kaan, you can see more details and explanation on the making in my other detailed videos! The amount of layers depends on the place in the instrument. Some places must be thicker to be stiffer while other places must be more flexible for the sound. You can contact me through my website www.timduerinck.be
What's the material of the translucent cello? Sorry, I know you mentioned it in the video, glass fibre? Amazing work, carbon instruments have been an interest of mine for a while now.
The classic C-bouts of a cello are not well suited to make in a composite material. This shape of the body is not really new, I think Chanot was one of the first violinmakers to use such a shape. The precise outline is my own design though and is based on just a few connecting circles.
Hi, I have another video in which I show and compare 3 cellos from other materials: Carbon, Flax and Glass fiber. I have also made 'hybrid' instruments that combine carbon fiber with flax fiber for example. So yes, all of that is possible and it offers many possibilities!
Hi Bruno, good questions! The bass bar is not made from carbon fiber because it is easier to give it the required stiffness that way. A carbon fiber bass bar is definitly possible, but not easy to get right! For the bridge, that's a whole other story, it has a very unique acoustic function and replacing it with carbon fiber is sure to have a large acoustic effect. It would require a large research on it's own before one could do that. For the reverb, I did not make the music or do the recording. These are artistic choices by the composer and cellist, so not for me to answer ^^
@@Knoight Both are carbon but 2:08 is unidirectional, this means that all the carbon fibers are in the same direction, while 2:16 is woven, so the fibers run in two directions. The fibers are what give the material stiffness and strength, so depending on how you put the fibers, you change the stiffness of the material in the different directions.
Hi Fedor, as you can see at 5:06 the cello had both a pickup and a small mic attached. Both were used to record depending on the sound the cellist made on the instrument (which one of the two was most suited).
Hi, this cello would be around 10.000€, I make custom instruments, so the price depends a little bit on what you want exactly. I do have a small waiting list for instruments. If you would like to order an instrument you can contact me, f.e. through my fb page facebook.com/AtelierDuerinck and we can discuss the details. All the best, Tim
"I hope you enjoyed the video". To be frank, no I did not. Sorry to sound so nasty. But you did not explain what you were doing, nor why. Then we did not get to hear the sound of the finished 'cello, just some sort-of miming. You did not compare the weight or tone with a wooden 'cello. You are clearly very skillful, but the video totally under-represented your craftsmanship. It is very hard to see even how you are forming the basic shape or how you are bonding the parts together. We are left with no idea about how thick the material was, why you used wood for the bass-bar and sound-post. We are not expecting you to teach us all that we need to know about how to make a carbon instrument, but this video gives us nothing, other than the impression that this is a slow and highly skillful craft. So, how did the final instrument sound? How were its tone, projection, dynamics and resonances. I'd love to know.

I watch this video at least once a year, realistically much more than that because I have to replay it at least once. Such a soothing video
I assume that, with access to that much carbon fiber, you've already built yourself a functional Batman suit...
S Class Fiber glass is better than Carbon Fiber :D
I can't help myself, but Batman wears latex, so is flexible 😉🙃 He was supposed to be a ninja really, not the Hollywood version.

Is there somewhere that I can hear a glassfibre cello? What are some f the points that would make me wabt glass fibre?
ruclips.net/video/TFi8VktpQbQ/видео.html Here you can hear a glass fiber cello. It has a really unique sound.
I wonder how heat molded pvc sheets would work for cello construction. With the seems being either glued or welded.
You mean to make a mould (instead of glass fiber) or to make the actual instrument? In case of the actual instrument the stifness to weight ratio of PVC is not that good, making it less ideal for instruments that rely on soundboards.

It would look great but non functional. Mainly for cosmetic appreance. Great job.
@@JOEGGGJOE Thanks! It would indeed look great. But at the moment I'm more into function.
Looks amazing! what material did you use to fill the neck,...and was it difficult to fit the pegs?
PU foam, the pegs (wittner fine tune pegs) were just fine :)
What type of wood is that at the beginning the gigantic slab one....???
It's not wood, It's PU foam (density 250kg/m³).
Slick. Looks like wood, until you realize that was the mold... Totally bad ass! My buddy could use a bass.
This is satisfying 😀😀😀😀😀
damn when u revealed the song was the cello itself I was shocked
Don't be fooled. If you run any cello through a bunch of synthesizers they all sound the same
Amazing, continue the research ! I would like to play it once :)
