Picture of 9 Piece Bongo Drum Shell
This will show you how to make a bongo drum (shell only) without a solid piece of wood.

Step 1: The Math

Picture of The Math
We chose to use 9 pieces of wood to make the shell. The math behind this is that esentially we are trying to make a circle. There are 360 degrees in a circle. we are using 9 pieces. two of the sides of each piece are being cut. 2x9=18, and then we divide 360 by 18. This turns into 20, so each side of each piece of wood will be cut at a 20 degree angle.
 
I've seen this construction method before. Just google "stave drums" it's cool stuff.

Nice drum shell - don't forget to post the rest of the project when you skin the top? On that note, how are you planning to stretch the drum head and secure in place?

Very interesting and well done.

About step 1, the math is perfect when the body is prismatic, but not when it is piramidal. In this moment I don't remember well, but I had that problem designing my plain mirrors based solar cooker.

I mention here that because maybe somebody want apply the same method for make a conic body.
