Upcycle Final Report: Tennis Racket Guitar

Design Process

For my Upcycle project, I constructed a guitar out of leftover household items, such as a tennis racket, a block of wood, and some L-brackets. The original inspiration for this project came from watching a street performer playing something similar years ago, and from the tradition of people constructing their own instruments. I had also recently seen a movie called It Might Get Loud, in which Jack White builds a guitar out of nothing more than a 2×4 and a bottle with guitar strings, which reminded me of the idea.

I knew I wanted to construct a guitar out of something I already had, so the next step was looking at the important parts of a guitar and how they work. Several components must work together for a guitar to be able to produce sound. For this step, I drew a picture of a basic electric guitar and labeled the important parts and what household parts I could use to serve that purpose on my design. After that, I drew a picture of what a tennis racket guitar would

Originally, I just wanted something that could emulate the appearance of a guitar and maybe have some functionality. My first couple of sketches were just of guitar shapes and I tried to think of items that looked similar. This idea changed after I did some research into DIY guitars and realized that to make a simple guitar that could produce sound would be possible with a few design changes. I had spare guitar strings at my house and several leftover brackets and fasteners from my senior design project, so I figured I could attach them to an old tennis racket that I had and use it as a guitar. I found an article on how to do exactly that online (link at the bottom), and so I used that idea for a few of the parts of the guitar. For my final design, I wanted it to produce sound with multiple strings and for it to be possible to modify the pitch of the strings similar to tuning an actual guitar.



Functionally, the tennis racket guitar worked for the most part. The bridge (made out of L-brackets and a piece of leftover wood) worked well and the spacers used to hold the back end of the strings did not slip.

The strings themselves played loud enough to be heard, and the pitch could be altered with the tuning screws on the neck of the guitar. The tuning screws were made by looping the strings through the neck of the tennis racket and tying them around a screw that had a hole drilled down the center. After they were secured into the neck, they could be adjusted by using a screwdriver to either tighten or loosen the screws themselves.



One problem with this design was that the tuning screws did not have a lot of material to be screwed into, and over time the strings started to go out of tune very quickly. This could be fixed on future versions by building a more secure tuning device, such as the worm drive system used on traditional guitars. Another improvement could be mounting a microphone or pickup onto the tennis racket under the strings. This could be used to amplify the sound, which allows for a lot more possibilities while playing it. Overall, this design worked well to emulate the basic functions about a guitar and I understand them a lot better after working on it.


Final Project

Aesthetically, I was originally going for something that looked like an old blues instrument. I wanted to have a worn look to it. Unfortunately, the tennis racket I had did not really have a vintage look to it at all, and the frame was mostly made of metal. After deciding to use the L-brackets for the bridge and neck part, about half of the guitar was metal. It started to resemble something that a person busking or a street performer would use. These people are usually creative and they can repurpose objects into something musical. My guitar wound up having a mismatched, stitched-together look to it and I thought that mirrors the street performer aesthetic very well.



If I want to continue to develop my tennis racket guitar, the next step would be to refine the tuning system, as I mentioned earlier. This combined with a source of amplification would be the main improvements that would need to be added. Ultimately, what I want to do is build my own guitar from scratch one day in my spare time. It is something that I have always wanted to do, which makes sense as an engineer who plays guitar. Working on this project gave me a lot of insight into what it takes to make a guitar work and a lot of information about their construction, which would be very helpful for when I build my own!

  • Wow, amazing post, this is great technique, I can’t believe how to make a guitar from a tennis racquet.. this very amazing. Really I will appreciate this post. htps://pickleballhube.com

  • Love how you made something useful that you could keep. The project goals were very good. The iterations really added to your design process. You also did a fantastic job of covering everything in your presentation. Some caps to cover the sharp parts of the design would be a good addition.

  • He got his idea from the movie Making it Loud, which is a documentary on guitars. He used a lot of design considerations and diagrams. I like that he labeled all the parts on a drawing of an actual guitar and then brain stormed what materials he could make it out of. It sounds like besides just making it aesthetically pleasing, he used a lot of math to figure out if this would work or not. I strummed the guitar and it actually sounded like a guitar which is very cool. He even demonstrated the sounds, and has an idea for the future to make it even better.

    It was awesome being able to hold the finished product! I never would have thought that one could turn a tennis racket into a guitar, so great job there! It was great seeing all the components that you used to create the guitar and how they all interacted together. Any plans for the future for the guitar? Are you planning on modifying so it can pick up sounds? I’m curious if shortening your bridge pieces might enhance the sound?

    What a cool idea! I like your explanation of your inspiration for the project. The design considerations slide helped created perspective about how you went about the design for the guitar, as well as your selection of the materials. It was also interesting to hear how you considered which materials could be used to physically construct the guitar, versus which materials would allow the guitar to have a pleasing sound. I really like the aesthetic you chose and the inspiration you found for it. What could you do in a future version to improve the ability to keep the guitar strings in tune, and how could you make the design a little safer by covering or removing sharp edges? Also, would it be possible to replace the tuning screws with something that could be manipulated by hand?

    In your presentation I liked the fact you brought your finished product with you. It’s really interesting to see a guitar made from an old tennis racket. Being able to hold the guitar in my hands let me see how structurally sound the instrument was. I would have doubted that the strings on the tennis racket could support and bridge and the added stresses that come with securing the bridge, but it seems to hold up exceptionally well. Are you planning on installing a device that would amplify the sounds, such as a pickup or microphone?
