How to Build Your Own Cajon Box Drum With Adjustable Snare

In this instructable I will be showing you how to build your very own Cajon box drum. We made 2 Cajon drums for under 50$, so around 25$ a piece. I will be entering this instructable in the Musical Instruments Contest, so please vote!

Things you will need will include: Wood- its up to you what type, we used 1/4 inch Birch Plywood for the drum faces. and 1/2 in Birch ply for the remaining 4 sides. Wood Glue. Screws- make sure they look nice because they will be visible. Snare Mechanism- You will need 1/2 of a standard snare wire set. You can find them here. Dowell Rod- 1/2 inch. The Tools You will need: Table Saw- or a handsaw if you do not have one. Screwdriver- one that matches the type of screw. Sandpaper- rough for getting the overall shape, finer grit for the overall finish. Dremel- or another tool that can be used to cut a circle. Drill- used to presink screws as to not crack the wood. Optional- Paint- your choice. Stain or varnish- your choice

We've all heard it, measure twice and cut once. The goal was to make the Cajon Drum 1x1x1.5 ft (length X width X height). We also wanted to make the box sit flush with the ground, which means you will not see the bottom piece of wood at all. This overall made it a little complicated to do the measuring and lining up of the box. In the end we settled on an ideal design that consisted of 2, 1/4 inch panels (used as the front and back panels) that were 18.5 inches tall by 12 inches wide. the two sides (left and right) measured 18 inches tall by 1 foot wide. the top was a square that was 12 inches by 12 inches. the bottom was cut as to fit flush with the ground and measured 11 inches by 12 inches. Look at the picture if your confused, excuse the handwriting.

Cut out the pieces for the box. Make sure that you tape over the lines to prevent the saw from shredding the edges. After you cut all of the pieces out, you can then build the basic box shape. Clamp the shape and let set. If you don't have corner clamps you can tightly wrap string or belts around the shape to help compress it. At this point you can add ribbing along the inside. We used 1x1/2x1/2 (LxWxH) blocks as ribbing along the inside to help hold the screws. Press these blocks into place and wipe away any access glue. Next you can work on the faces, use a small amount of glue to secure the front onto the box. Use weights or books or something to put pressure on the wood. Next take the back, and cut a hole about the size of a CD in it using something like a dremel or other tool.   

The goal for this was to keep it simple, but make it effective. The snare is what really sets apart the Cajon from just a wooden box. This way of attaching a snare allows you to play with no snare sound, or a lot of snare and everything in between. We took a 1/2 inch dowel rod and cut it to about 13-14 inches. We then cut a hole in the side of the box and slid the rod through. On the other side of the box directly across from the hole we put a block of wood with a hole halfway through it to hold the other end of the rod. We secured the rod inside the box by gluing a wheel to the edge. Look at the pictures to help follow along. On the outside of the box we made a "gear" out of spare wood, and a "toggle switch" that would keep the snare from bouncing back. Super Simple, and Super Effective.  Cut the entire snare in half and screw one half to the rod. you can turn the gear, and press the switch into place to keep it from turning backwards.

Use some glue to secure the back onto the box. Take some screws and pre-sink the holes into the wood very carefully. Use some screws to tighten the back and front into place. DO NOT INSERT SCREWS IF YOU WANT TO PAINT/STAIN/VARNISH YOUR DRUM. its best to do the screws after you've done what you want to do.

Decorate it your way. I printed off my name in a custom font and used a CriCut machine to outline it, and used it as a stencil. I then took tape, and made 3, 1 inch stripes going up and over the box and sanded them to make it rough.  On the remaining side I wrote "This Side Up" and painted it on also. On the other box we put my brothers name and a logo he liked. The project turned out so much better than I could have ever thought. They both sound great and compared to store made versions they look a lot cooler. The entire project was a success in the quality and cost. Thanks for reading!
