I was chatting with a fellow at work, and discovered that he is also a musician, albeit more serious than I am, and he learned that I am a woodworker, also more serious than most people, and the conversation turned to cajones, (A drum made entirely of wood – originally from Peru, according to Wikipedia, made from boxes) Relatively recent versions include an octagon bongo-like cajon. Traditionally, they’ve been a box you sit on and drum on the front surface, but I’ve been thinking of how to have one and not have to bend over.

So, he wondered if I could make him a round one. I agreed to try and as usual for me, I started with a prototype made of cheap scrap. It was, as the saying goes “a learning experience”. But having learned from the experience, I went ahead and spent several weeks of free time producing the one in the first picture.

It’s made of 30 pieces of 3/4” Birch, beveled, glued and sanded to a nice cylinder, with a 3 3/4” sound hole and top and bottom made of 3 mm birch plywood.

For the final glue up, I cut a circle of plywood fitted and strapped around the center (picture 4) to make sure that it really WAS a cylinder. Then I used many of my smaller clamps to make sure that the alignment of all the staves on each end. More on how I cut the circle on another project post.

It’s finished smooth, inside and out, and he loved it. This might be a lousy business model since I didn’t charge him anywhere near the amount of time it took for me to learn how to make it, but on the positive side, I got to play with the concepts, materials and skills on somebody else’s nickel, so I view it as a win-win.

I’ll be posting the second one later today.

You never get what you are worth monetarily speaking. You got experience and as you said, someone else paid for you to learn. Cajones are on my todo list, but I am not happy about the box type.

Hi OldSkookModder,

I don’t care about what I might be worth monetarily speaking – I was enjoying the experience, and it was a nice addition that someone suggested something that I could learn from.

I wasn’t happy with the box type either – that’s what led to the conversation at work. But I’m grateful that some unknown person in South America saw something in a wooden box that no one else saw – and made something of it.
