Wonder if you could make it work with a bike dynamo?
Sorry for the super late answer! The hardness of the wood is the important part. Softer woods give you a more mellow tone, hardwoods make the instrument louder(seeing your instructables page makes me think I don't have to go into detail here :D). Spalted maple would make an exquisitely beautiful kantele. I hope you still have some left!
