I received an email from Ted Derryberry recently showing me a plywood cajon he made for his percussionist friend. I made a regular cajon a few years ago, but had never heard of a bongo version. As with its larger, deeper sounding cousin, cajónes are traditionally made with plywood, and have a thin tapa (top) made from 1/8″ plywood which acts as a drum head. Some, such as the one Ted made, include snares inside that press against the tapa. I left them out of mine.
If you have trouble finding 1/8″ plywood, it is often sold at lumberyards as a “door skin”, and I presume is used to dress up a drab door. I have also found small sheets of thin plywood at some craft stores. You will only need a piece that is about 7″ x 16″. And if you have no luck finding 1/8″ ply, I suspect 1/4″ ply would sound pretty good. In larger cajónes, the thin plywood flexes to allow for a deeper sound. I used 1/2″ plywood for the rest of the drum. It’s sturdy, yet lightweight.
I jointed my pieces together with rabbets on the edges of the front and back, into which the sides fit. I cut dadoes (grooves) on the inside of the front and back to hold the divider, which gives the drum its two tones.
On standard cajónes, the tapa is screwed in place. This allows the player to adjust the tightness of the screws to create different tones. Due to the smaller size of a bongo cajón, I felt screws were unnecessary so I simply glued the tapa into place.
I angled the two short sides in at an 8 degree angle. This makes the drum more comfortable to hold between your knees if you play it that way. There seems to be no “right” way of playing a plywood bongo. I also added curved cutouts on the bottoms of the sides so the sound would resonate out if the drum is played on a firm surface.
Super Simple Version
If you don’t have a lot of tools or space, you can easily make your own plywood bongo drum! Cajónes were originally built by resourceful individuals using crates or old drawers. I like that the tradition of using an inexpensive material like plywood remains. It is somewhat ironic that music stores sell such expensive ones! So if you are a musician, make your own: it’s way cooler.
Use a handsaw to cut the plywood pieces to size. You might even be able to get them cut to size at your local home center. If you can find free wood, all the better! (Be interesting to try this with pallet wood.)
You will need:
- 3 boards that are 16″ x 6″
- 3 boards that are 5.5″ x 6″
To assemble it, just butt the pieces together and glue them. You can even use regular white glue. You will need to clamp the boards together to dry. If you don’t have clamps, you can nail or screw the pieces together. Still use the glue…the fasteners will act as clamps. Let the glue dry for a couple hours and you’ve got a bongo cajón!
It will sound good if you play it on your lap so the the sound can resonate out the bottom opening. You can also experiment by cutting some sound holes in the sides and see how that sounds.
