Hello everyone

I've joined a local drum circle 3 months ago and need to practice at home. I need a djembe - but instead of buying one I want to make one.

My friend is a woodturner and can craft the actual piece.

There is also a local hardwood supplier that can give me freshly cut oak pieces for free.

I just need to design and make a technical drawing for the drum.

I measured some existing drums and made dimensional calculations (assuming a djembe is a Helmholtz oscillator).

Could anynone check if calculations are correct?
