kzbin.info/www/bejne/infMaYmhqdWEmLM Here you can hear a glass fiber cello. It has a really unique sound.

Wow. I'm sorry, but that is a pretty harsh comment. I assume you did not realize this is the condensed video of a large 3-part series you can find on my channel: Part 1: kzbin.info/www/bejne/bYnFeIaFpcqJrrcsi=W89vSjOTaP5Bp3fk Part 2: kzbin.info/www/bejne/iXe5YWCli55norcsi=MsCCLmBtpzs1zr4U Part 3: kzbin.info/www/bejne/lXaXf3iors1pl6ssi=GaaIHSVCV8gOGiGo If you want to hear the sound of the finished instrument, there are more videos on my channel with comparisons and recordings of a quartet in a professional studio. If - after seeing these videos - you still desire more information, I would invite you to read through my PhD book, which anyone can access through this link: drive.google.com/file/d/1ptRsuYhOvl-Ui4afCvU6P6lZpWbpM81P/view?usp=sharing This condensed video is made for a wider audience as an introduction, it has more views (atm 54K) than all my other videos combined precisely because it is shorter and more condensed. I am not a professional youtuber, this is just a (free) video I made with allot of efford and love. I'm sorry it does not suit your needs perfectly.

@@TimDuerinck I'm so sorry. I did not know that this was a summary video, but bear in mind, that if this is the only video someone sees about your work, and not the fifth, your viewer may feel as uninformed as I was. I eagerly await listening to the sound of your 'cello, so thanks for the links.

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

Tim, this is not meant as a criticism of your serious efforts, only my opinion of what has been the result. Maybe, next these will be mass produced, as they can now be, but for cloned babies in an alternative universe.

Hi Lucas, yes, construction can be done with a seperate neck. But as you see me do at 5:39, the angle of the neck can be changed when the top plate is glued on the body. So it is easier, less work, and stronger, to make the neck projection correct at this moment and not make a seperate neck. I did make a seperate neck for a double bass recently, but that's a less standardized instrument then a cello.

@@TimDuerinck Got it! Thanks you

Well, you said it yourself already a little... on a phone speaker you will not be able to tell. Also: I'm not a great player. I assure you a better cellist can easily make the carbon or flax fiber cello's C string sound 'rich', 'dark', 'powerful' and 'open'. I suggest you listen to the video of a later flax fiber cello on my youtube channel. It's a better recording and a better cellist! And also maybe listen with some good headphones or something instead of your phone speaker ;)

Hey! That is confidential information I'm afraid ^^

So much for sound experts.

www.easycomposites.eu/model-board-tooling-board-block Easy Composites sells boards up to 1500x500. The one I am using here is the PU240 Medium density. If you need larger pieces you can easily glue them together. I found conventional white wood glue to work just fine for this!

thank you!@@TimDuerinck

Making all those moulds, parts and then assembling them would be allot(!) more work. Also every glue joint is a weaker point within the instrument. So having as little glue joints between different parts as possible is definitly an advantage for durability. The advantage of this method is also that the moulds can be reused. So construction of additional instruments also goes allot faster then when you would make all parts seperate. So to conclude: I don't really see why you would want to do that or what would be the advantage.

You can try to make a baroque copy ?

And have you test to build a cello with different part of fiber ? Thanks for your response

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

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, 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!

@@TimDuerinck Thank you! It's fascinating to see how one can duplicate the behavior of a wood instrument using modern materials.

I have not made those smaller instruments so I couldn't say :)

These days I have switched to PUfoam and carbon fiber instead of wood. Works just as well. This was still wood as I knew how to make a good wooden bass bar but not yet how to make a good carbon fiber bassbar

Drawing a beautiful and good arching for the CNC machine is VERY difficult. I tried but couldn't get the precise arching I wanted. For me, as a classically trained violin maker, it is much easier and faster to just sculpt it as I did in this video. Once you then have the moulds you can reuse them, so it safes time for later production.

@@drduerinck alternatively there are copy machines like for key cutting and wood work. You are just talented and skilful.

​@@drduerinckHow do you account for plate tuning?

As far as I know there is no school or place really offering classes in this. I do consulting for people who want to make composite instruments, if you are interested in that we could arrange something like that. But in order to make instruments just with consulting you need at least a good practical knowledge of classical lutherie to start.

@@TimDuerinck oh okay. I'm completely new so I want to learn Luthier stuff but I don't know that yet. 😞

@@8Phoenix8 In that case I would suggest to first go to a classic violin making school or do an intership with a conventional luthier! All the best, Tim

Cool! Thanks!

Hi Job, using multiple fibers is definitly possible, but it's not really a simple case of 1+1=2. There are certain restrictions to take into account for example in order to not have your piece warp during construction. There are some other issues as well. I have created violins in which the top plate is made from a different material than the body (ribs, back, & neck). That's the easiest way to make a hybrid.

@@TimDuerinck that makes sense - like the top and back of a traditional instrument are made from different kinds of wood. Did you like these hybrid violins?

@@jobterhaar yes, although I always make my top plates differently than my back plates, even when working with the same fiber. The one I made with a flax fiber top plate and carbon fiber body was especially liked by many listeners and players looking for a warm and easy sound. I do like them myself, but I also really like to push the boundaries of what is possible with just one material, because depending on how you use this material it effects the sound.

@@TimDuerinck I'm curious to try or hear some instruments in the future!

@@jobterhaar always welcome to visit my workshop and try some instruments!

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

Hi, yes, I'm a classicaly trained violin maker. The pattern making process is largely based on that knowledge. The other video's show more composite materials, that I learned during a short internship, through youtube video's and trial and error :)

@@TimDuerinck very cool! Thank you for sharing your process of making that carbon cello! Super interesting stuff!! I love the sound of the flax fiber one as well, very nice sound!
