My friend and I attempted to make a cello--these are the results. 
1) We made a functioning cello, as well as a bow from scratch.  The main body of the cello i used plywood, not traditional, but soaked- and compressed pinewood can become pretty dense and resonates well, also it bends well! For the fingerboard, I'm not sure what kind of wood it is, but if you go to any local home improvement shop, you should be able to find some railing. Also, i used regular wood glue to glue the body, then I added hot glue where i felt necessary. The bridge and peg box are oak, the only metal pieces are a bar near the area where the neck meets the peg box, and the strings which are regular cello strings. All the tools i used i either own, or in the wood shop at my school, I list some of them later.. You can play all the regular notes on  a real cello from C2 to F6. 
2) We began the project for an event called Sound of Music in the New Jersey Science Olympiad
Competition, in which we placed second at states in. In this event, we were required to build a treble instrument, for which we built a flute, and a bass instrument, for which we decided to take on the ambitious project of a cello.
We were also required to arrange two pieces of music. However, the cello soon became the
centerpiece of the project. Beginning as a simple outline, the cello took weeks and months to
3) We began the construction of the cello, including the faceplates and sound post, in Justin’s
 garage. But in order to make the more delicate pieces of the cello
including the bridge and the end pins, we worked in the woodworking classroom in our school.
This room had both more powerful tools as well as more delicate tools that we could use to
construct the more difficult parts of the cello.
4) The first obstacle we had to overcome was the sheer magnitude of the idea of building a
playable cello from scratch. The most difficult parts of the construction included building the
bridge and the other more delicate parts of the cello. However, we were able to use our school’s
woodworking classroom which helped us tremendously. The proudest part of the experience
happened when we were completely done building the cello and we played it for the first
time. We were so excited and shocked that it produced such a deep, rich tone. After months of
construction and weeks of practicing, we were able to play actual pieces of music. If we had to do it again, we would have used the woodworking classroom to begin with because the tools we used in Justin’s garage made it take hours to build
one piece.

A lot of instruments are made from non-traditional materials. I have an inexpensive mandolin and owned a Harmony archtop that are both made from "laminated wood".
When I worked for a music store, we farmed out our violin repairs to a shop in Broad Ripple where they had a bass in the rack that had a body made of pressed aluminum. The story was that they were built during WWII for Army orchestras because they were light, rugged, and not made from as strategic a material as Spruce.
It sounded OK

Hi, there.

Thanks for your instructable. It's very nice.

I just want to add a piece of information which is actually a piece of wood to your cello. :)

It's missing its "soul": the sound post. It's the small rod that connects the bottom and the lid, below the A string, inside the "box".

You can find more info about it here:


And how to place it here:



You'll see that after this, your cello will gain a new soul and life when you play it!

This is pathetically ingenious (I hope that came out as a compliment).

Thank you again for the cello.
Do you know the cubic inches of the bouts?

Thank you for your cello. I've made one out of cardboard. It's an 'emulated cello - viol da Gamba'. My next build will be of 1/16 inch pine. Oh, G-D willing. Again thank you for your cello.

This should help...


Hi there!
I'm considering doing this myself. What did you use as a frame to bend the wood?

I made a cut out of the cello out of scrap wood, and used clamps as well as weights to hold it down

I despair that so many "Instructables" are so poorly written and by no means is this one the worst I've seen but it is above average (or should that be below average?)

Previous commenters have pointed out the usage of "finishing line" instead of "fishing line" and "table [jig] saw" instead of "scroll saw" (with the ubiquity of Google or Bing search it should take seconds to find out the right term) in this document. They could have easily started with the first sentence "So i'm attempting to make a cello with my friend.. and here were the results." Here we have a confusion between present tense "attempting" and past tense "here were". "My friend and I attempted to make a cello--these are the results" or "My friend and I are attempting to make a cello and this will be a documentation of the results" might be better depending on when the text is being written.

To quote fully from AutoDesk co-founder John Walker's Reading Unedited Text http://www.fourmilab.ch/documents/strikeout/ :

'[Some argue that] the Internet is a dynamic medium; there's no time to carefully proofread text before posting it.

Consider what the folks who advance this argument are saying. "I'm in such a hurry that I can't be bothered to critically read what I've written before I dispatch it to be read by hundreds, thousands, or millions of other people. My time is so valuable, the five or ten minutes it would take to spelling and grammar check my posting, then read it over for coherence and edit it accordingly cannot be justified. Better all of my readers spend the time to figure out what I was trying to say than I spend a minute making it clear." '

Perhaps this site needs a cadre of editors to review first-time submissions? They could provide feedback to the poster to improve his or her writing. In the mean time I would suggest that posters ask three to five people to read their text and make suggestions for improvement. Perhaps then their writing may deserve the superlatives commenters give it.

I highly recommend borrowing the book How Not to Write Bad, by Ben Yagoda, from your local library. It is a quick read and very useful.
That proves that we are all human beings (but I don't know about you, I think you're an exception to that) :)

Are you just constantly complaining about things? You always talk about how poorly written instructables are and I've yet to see you publish a single one. If you want to offer friendly criticism that's one thing, but sod off if you're gonna just complain about everything.
This man obviously spent a fair bit of time working on this project.
Why are you insulting him?
If you have nothing positive to contribute to the article why even bother.
As far as "How Not to Write Bad" how about you spending some of your time reading "How Not to be Obnoxious"
I'm just glad he posted this. There were some typos, but nothing I would cry about. It was a very good instructable, considering that it's the only one I know of to make a cello from scratch.
I understand you were trying to help, but it came off slightly offensive. Just thought I'd let you know.

Thank you for the feedback, it will definitely help in writing future instructables. I have no excuse for my many typos- and this comment is a testament to how little time i have spent revising the text. Hopefully this experience will help me learn and grow, again thank you for the constructive criticism.

How does a Cardboard Cello sound? I'm making one of out of Cardboard (well, Chipboard actually) and I'm making it stiff enough to resonate the sound and take the pressure of the strings... but i need help "how do I make chipboard stiff enough? what chemical can I use to stiffen it (not fiberglass please)? some chemical that doesn't change the acoustic properties of the paper...

How much did all of the materials cost?

This may be the solution to school orchestras experiencing a cello shortage (thanks to "The Piano Guys") I'm now inspired to make one of my own!

I noticed you don't have the bridge on the finished version does it not work? how about a sample video of it in action luv to hear it thx
I added a video to step eleven!
greenmagic2 years ago
Can I please a audio sample of this violin? Have you ever thought of an electric version?
I've added a video to step 11! Currently I'm working on an electric balalaika, should be up soon
Its a cello.

Nice. I only have one little unasked (mea culpa) tip for you: which I fell over, once, making an upright bass (not on instructables).

Your bridge, the thing with the hearts in it needs to be quarter sawn (kwartiers gezaagd: in Holland-isch). If I say this right. This means the lines of the wood need to be horizontal, yours is vertical I believe.
Why is this?
Because of the vibrations, which give the sound, etc. Vertical lines will break or "bite in" over time. Also every snare should meet air in the bridge; that is what the "hearts" are for. This also has to do with the vibrations of the bridge moving to the body etc.
All in all I do like your project!

I really appreciate this project. I've been teaching myself to build instruments for a few years now, and it's nice to see what a couple of non-professionals can accomplish.
If you ever want to, feel free to bug me and I may have information or design information about some instrume t you might be building. My current project is 3 simultaneous lyres. :-)

Since I have deep rooted conections with Paraguay I want to share how others have made insturments. http://www.kickstarter.com/projects/405192963/landfill-harmonic-inspiring-dreams-one-note-at-a-t?ref=live
great group. I've been following them on Facebook for a while now

This is amazing! Well goes beyond the level at which I made my instruments, the caliber of sound compared to the materials used is amazing- simply amazing.
Whoa! You just lost me. One moment you're cutting out some blank as a reference, then you're putting pieces of wood in a pan, now most of the cello is complete. What happened? How do I construct the rest of the cello.
jaxboy2 years ago
I so wish you had shown how you did the side bending, as it looks awesome! To me, that would seem to be the hardest part, because you can glue the top and bottom on and then trim them to fit. Your side piece looks quite professionally done. I'm impressed. What was the wood you used? It would have been nice to get pieces of mahogany or oak. How many pieces did you you use, how thick was it, and how did you join the ends together? Whatever you did to make it, you did a very fine job! How did you curve the top and bottom as well? I love music, but have no talent. I have had a violin, a viola, a,mandolin, several 6-string guitars, and now own an electric bass which I use to play along with my music. It sounds terrible most of the time, but occasionally I will get into the right cord and play along well. I love the sound of the cello, and I think this will be my next indeavor. That you for giving me the inspiration to tackle it. I, too, Can't wait to hear your video of you playing it. By the way, there are several sites on ebay that sell pegs, nuts saddles and bridges for very little. "songtieling" seems to have god prices.
:"in this picture my G string is missing"
I laughed so hard at that.
I'm sorry I'm so immature.

i want to listen how it sounds....make a video

that was my first question. I sort of assumed it would sound terrible, but then I remembered a video I saw on youtube of this old Mexican guy playing beautiful music using a plastic 2 liter coke bottle as an improvised trumpet, so I suspect that it sounds wonderful.
