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:

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.

Step 1: Tools and Supplies

Here is a list of tools and supplies that I have used for this project

- Drill
- Sander
- Jigsaw
- Circular saw
- Grinding machine (optional)


Multiplex plywood for the resonating box and sizzle effect (snare sound)

- 290x130x10 mm (2 pieces)
- 200x130x10 mm (2 pieces)
- 290x180x10 mm (1 piece)
- 290x30x10 mm (1 piece)
- 100x21x10 mm (1 piece)
- 310x200x4 mm (this will be the slap surface)

Pine wood for the inner frame:

- 140x20x20 mm (2 pieces)
- 290x20x20 mm (2 pieces)

- Glue for wood
- 10 wood screws
- 1 classic guitar string (A)
- 2 t-nuts (size 6mm)
- 2 hex socket head screws (at least 6 cm long)
- Wood finish

- 4 rubber feet
- 4 washers
- 4 bolts
- 4 nuts

<p>Hi!</p><p>I've recently made a cajon based on this design and it works well except for the snare effect. I'm finding I'm getting an audible &quot;note&quot; from the guitar strings rather than just a snare effect. Any idea what I need to do to fix that? Thanks!</p>
<p>I know this -ible is a bit old and you have probably long since moved on but I used your basic setup and instructions to make my mini-cajon. Thanks for sharing the process. I think I'll upscale to a full size. It sounds nice though the &quot;sizzle&quot; is a bit weak. I'll probably remove the top and add another guitar string or two to give it a more snarey sound. Also, I realize it's probably a good idea to add a &quot;stop&quot; for the socket head screws since one could accidentally unscrew them to the point of disconnecting the Tee bolts. Thanks again.</p>
<p>What was your approximate cost to make a mini cajon? I would like to make 60 with my students and wondering if I can manage the cost. Thanks for any input on cost, additions/subtractions/substitutes in building materials you believe would make the project more cost effective or simplified without compromising the effectiveness of the instrument. </p>
<p>Hi, apologies for the slow response. The overall cost was about 20-25&euro;. To minimise costs you can consider: 1) modifying the sizing in order to optimise the use of your plywood sheets (i.e. reduce scrap bits); 2) substituting rubber feet with recycled material (plastic bottle caps?); 3) not applying finish (or make it optional for your students to do at their own cost - though it does not sound great). What you really can do without: A) plywood (cheaper options such as MDF would not work); B) guitar strings (snare wire would be even more expensive); C) glue and hardware. I hope it helps.</p>
Would you ever consider manufacturing?
Hi olesgreb, <br> <br>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?
Hi colt01 <br> <br>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. <br> <br>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. <br> <br>I hope I have answered your question. <br>
Can we hear what it sounds like?
Hi Kiteman,<br> <br> 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:<br> <br> http://www.youtube.com/watch?v=CjsMwj-WgA4<br> <br> For a comparison, the Cajonito (by Schlagwerk) uses snare wires:<br> <br> http://www.youtube.com/watch?v=tPVr8FCgCN0<br> <br> vs<br> <br> <br>
Nice job!<br> <br> By the way... next time you post a reply, click on &quot;Rich Editor&quot; then when you put your links in, you can highlight them and make them an active link like this...<br> <br> One of several videos on the web:<br> <br> <a href="http://www.youtube.com/watch?v=CjsMwj-WgA4" rel="nofollow">http://www.youtube.com/watch?v=CjsMwj-WgA4</a><br> <br> For a comparison, the Cajonito (by Schlagwerk) uses snare wires:<br> <br> <a href="http://http://www.youtube.com/watch?v=tPVr8FCgCN0" rel="nofollow">http://www.youtube.com/watch?v=tPVr8FCgCN0</a><br> <br> 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...<br> <div> <object height="360" width="480"><param name="movie" value="//www.youtube.com/v/CjsMwj-WgA4?hl=en_US&amp;version=3&amp;rel=0"><param name="allowFullScreen" value="true"><param name="allowscriptaccess" value="always"><embed allowfullscreen="true" allowscriptaccess="always" height="360" src="//www.youtube.com/v/CjsMwj-WgA4?hl=en_US&version=3&rel=0" type="application/x-shockwave-flash" width="480"></embed></object></div> <br> I hope that helps you.<br> Jerry<br>
Hey Jerry, <br> <br>Thanks for the heads up. Will do next time ;) <br> <br>vs
nice one, have been planning to build one myself for my son! i believe this is a good guide!
cool, thanks
That's really cool. For those interested in what it sounds like I found one with strings on youtube <br> <br>http://www.youtube.com/watch?v=X4ByERhIIz0 <br> <br><iframe frameborder="0" height="315" src="//www.youtube.com/embed/X4ByERhIIz0" width="560"></iframe>
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
I like the use of the log
