I'm gearing up to be making a Cuban style bajo cajon soon, maybe even this week, or possibly next. I've been fortunate to have corresponded with several individuals that either own or have measured cajons owned by notable rumberos. Also other individuals have taken the time and posted dimensions of cajons they have made on the web.
I've always liked the simplicity and versatility of the older style boxy cajons. I like how they are a chair and an instrument, you can play them with hands, sit on them, use spoons and play palitos. Also you can stick stuff inside it and carry things around in it like, well, a box!
Seems like some of the manufacturers are charging quite a bit for cajons, which doesn't seem right, to me at least. I mean cajons were originally free, or nearly so. Still not everyone is crafty, so there is nothing wrong with spending $300 on a wood box if you are so inclined. The Peruvian style is most common variant, probably because of it's association with flamenco. Seems like there are all kinds of curious cajon configurations; round, octagons, trapezoids, batajon's, conga cajons, bongo cajons, etc.
Me, I want a deep bass cajon. I want a instrument that is completely different than a conga, so I'm going for the sit on the top, played between the legs, suitcase shaped bajo cajon.
In preparation for my new project, I made a documentation of all the cajon dimensions I have collected, with the source and pictures when available. I'm posting this document here for free download to any rumberos out there in the blogosphere that may be interested in making their own bajo cajon, or just in the cajons in general.
