This instructable describes the process to build a small cajon similar to commercially available ones. I will call it mini cajon, but the instructions can be easily applied to build a full size cajon.

At the time of writing I could find 3 instructables on how to build full size cajones:
http://www.instructables.com/id/How-to-build-a-cajon/
http://www.instructables.com/id/built-your-own-Cajon-for-less-than-25-Euro/
http://www.instructables.com/id/How-To-Build-Your-Own-Cajon-Box-Drum/


So why bother with another instructables? The reason is simple: instead of using snare wires to obtain the snare sound I have used a guitar string. Many cajones are built in this way and I thought someone out there might find this interesting.

Unlike full size cajones, you cannot sit on a mini cajon but you rather hold it between your legs at knees height when playing it. It is a very compact and portable solution when you need a good percussion instrument on the go.

Would you ever consider manufacturing?

Hi olesgreb,

thanks for your comment. I do have sold a couple of cajones but I have never thought to do it on a large scale. They are still average products that anyone who does not want to invest on a high end branded one can easily build. You should give it a go ;)

How tight do you make the guitar string?
VortexSurfer (author)  colt011 year ago
Hi colt01

the tension of the guitar string is adjustable from the outside of the cajon using the hex cap screws: by tightening them the slider will move towards your hand increasing the tension of the string. It allows you to find the sound that you like the most and to change easily sound (perhaps removing completely the snare effect) simply using an allen key. When you are setting up the string the first time I would suggest to make it as tight as possible and to have the slider in a central position on the scews (as shown in the pictures) so that it has some leeway to move in both directions.

Thank you for your question: clearly I did not explain it well enough in the instructable and I am going to edit it to include these informations.

I hope I have answered your question.

Can we hear what it sounds like?

Hi Kiteman,

unfortunately my mini cajon is back in Italy and I currently live in Melbourne... To get an idea, I have drawn inspiration from the Palito Cajon produced by Meinl, which is built in the same way. One of several videos on the web:

For a comparison, the Cajonito (by Schlagwerk) uses snare wires:

Nice job!

By the way... next time you post a reply, click on "Rich Editor" then when you put your links in, you can highlight them and make them an active link like this...

Or, if it is a YouTube video... copy the EMBED code from the YouTube Link, then click the filmstrip in the rich editor and paste... then you get this...

I hope that helps you.

Terrific variation of the traditional cajon.
Great build. I am a huge fan of cajons, and I believe the guitar strings have a better sound
