Carbon Fiber Tailpieces by Kenneth Kuo shared Santiago Cañon Valencia's post. ... See MoreSee Less

For those of you that asked, this is my new Carbon Fiber Tailpieces by Kenneth Kuo, which was custom made and given to me. It only weighs 28 grams and it is made out of carbon fiber and composite materials. I have been using it for a few days now and it truly is fantastic! You can find detailed info here: tonaltailpiece.com Some people have also asked me about my new bridge so I will be making a post dedicated to it tomorrow.

A customer came in today ask me to rehair this bow for her because other shops refuse to do it. After I cut the hair I realized whoever rehair It last superglued the shell slide and it is completely stuck. Upon removing it, the shell cracked and came off. After rehairing it and built a new slide, I could not find a piece of shell to dress it up so decided that this probably match better with this carbon fiber bow.... ... See MoreSee Less

Manufacturing Process

Carbon Fiber(CF) is basically carbon that is woven in to threads and act as a fabric. It is usually a cross weave just like any other fabric but there are various sizes of the weave, the most common for what I am doing is using a 2mm x 2mm.

As a piece of fabric, it is weak and flexible but once the epoxy resin is added, it is incredibly strong compare to other materials of the same weight.

The most exotic cars, bikes, and even now drones are using CF in the construction mainly to reduce the weight.

One thing that no one has ever pay attention to it is the way it sounds. Because of its density after the resin cured it has a natural ringing effect that is pure natural. Because of how hard and light it is, it is able to transmit vibration in a much faster time.

CF is very brittle, unlike the Kevlar which absorbs vibration, it will shatter upon impact while the Kevlar will not and that’s why Kevlar are used for making bullet proof vests etc. but it is terrible for transmitting vibration or sound.

Making a CF part is time consuming, there are no short cuts when doing it the correct way and that’s why they are very expensive. Each step takes tremendous effort and waiting for the epoxy to dry can take up to 8-10 hours each time curing in the oven at 180 degrees. It’s similar to making a violin. You have your material, pattern, lots of extra material that you throw away, you make a mess, you glue it, cut it, shape it, varnish it (clear coat), you sand it, polish it, drill holes etc..

I have spoken with many experts in F1 racing and everyone agree that each piece is made by hand and the mold for each part can take weeks to refine. That being said, this entire CF tailpiece experience has been amazing that I am able to learn and discover how we can use this amazing technology to enhance our beloved instruments and set it free at last.

Grinding away excess resin, this process needs to be done in a enclosed environment as the resin powder in this stage is bad for your lungs

Thanks to my dear friend Renato, we are able to use a 3D scanner to scan the original tailpiece and create additional designs base on the original measurement and curvature. You got to love modern technology.


Please put on your headphone, get ready for something amazing!


Maybe I should be making marimbas instead of tailpieces! Lol, 4 different tailpiece 3 different pitch.
