I could buy one. You can find a cheap one for around 200 US dollars. But what would be the fun in that?
Additionally, Percussionists are notoriously protective of our instruments (As all musicians should be). The problem is drums and mallet percussion instruments like the Marimba and Timpani are very large, very expensive, and about waist high. So other non-percussionists frequently mistake them for tables.
This Djembe is going to fix that problem by doubling as a table. This is an easy fix, all you have to do is place a glass top on it.
First you have to decide what "build" means to you. To me it means carve up a tree myself.
However, if you prefer you can buy ready made djembe shells from suppliers such as African Rhythm Traders. If this is the best option for you, you can skip the next few steps of the instructable. However this instructable will focus on making the shell, and I'll refer you to some other sources for tying the ring knots and verticals.
Step 1: Identifying a Tree
In my search, I looked for a tree which had already fallen.
The advantage is, half the work is already done for you and the lumber has already started drying (more on that later). The disadvantage is worms. If the tree has been down for some time, worms will have already started decomposing the material by burrowing holes in the material. This can be fixed later, so don't let that scare you.
Regardless of the tree's condition, try to get material from as close to the base as possible. For one, the diameter is larger, which will allow for a larger drum. Two, the "heart" of the tree is bigger (see pictures). I suggest you section off 2 or 3, 40 inch lengths to make your drum out of. 40 inches leaves plenty of work room and the additional logs can be used to make more drums, or as backup material.
