I’ve finally put the diy cajon drum build process in a single post which now includes a demo video.
*** Now updated for single page view and video demo. ***
For my next project I decided to make a lap sized cajon. I’d seen a smaller flatter Cajon in Cuba which looked pretty handy and I’m aware that Meinl make a good looking Bongo Cajon.
I’ve put together some plans for building Cajon Drums. There may be a some errors but it should be enough to get you started. The plans are available here Cajon Drum Plans.
To follow the full Cajon build process with images and a demo visit the new collated Homemade Cajon Drum page.
For details of my diy Lap Cajon and a video of the drum in action read how to build a lap Cajon.
Good luck with the Cajon construction.
With the frame built the remaining items are the playing surface and resonant side. As previously described I planned to use an angled resonant side on the lap Cajon to try and create a difference in pitch end to end. This seemed to be simpler to construct than two separate chambers and should provide tone across the length of the drum.
Both the resonant and playing surfaces were cut from 3mm plywood. The resonant surface was glued into position at an angle supported by wood strips and clamped to give a good seal. Once this had dried the playing surface was then glued and clamped into position.
I decided against adding any snares / strings to this Cajon to give more of a bongo sound. I also decided not to cut a sound hole as I was unsure how this would work on an angled surface but it may be something worth experimenting with in future versions.
To finish off the project the edges were rounded and the drum given a couple of coats of Danish Oil.
