I’m purchasing some Black Walnut from a guy who told me it’s been sitting around since the 60’s. I brought my MC meter with me when I looked at it and it measured 6%. Lowest reading I’ve ever gotten from wood. It looks good, he tells me its never been stored outside. The ends are raggedy and it’s only rough sawn with some slight planing on one side just to show evidence of final surface condition. A buddy of mine claims it’s possible the wood could be ‘too dry’ and hard to work. His example of what he’s talking about is it could be hard to drive a nail into it because the wood is too hard. I don’t understand what he’s telling me, or believe in what he’s telling me. Does wood harden over time as it ages? I’m confused. The walnut looks great, I think I’m getting a great deal. There’s 500 bf of it, so if I’m wrong, I’ll have a lot of material I can’t use and wasting a lot of money too….
