I have a question that you might be able to answer. I have a whole grove of Persimmon trees, some 14-16" in diameter. I was going to cut one this spring, but noticed from Wikipedia that the grain is interlocking. That conjures up images of Elm and Hickory to me, which is a wood that will not split easily. Can you tell me if your friend had any trouble splitting the staves out?
