It's not really hard to make, but getting all the materials to make them can be.
Where I live, slate is almost everywhere I look, but finding an old turtle shell is the tough part.
I was shown how to do this by a late friend of mine, so I can't take credit for coming up with the idea, but a turtle shell does make a good sound chamber.
