Thanks everyone!
So, I take it that quarter sawn would not be desirable in walnut, and only ok in a lower trunk cut with a perfect lay out for the wrist for hard maple?
I've used sugar maple from my area before, for a few long rifles and lot do bow laminations. Most of the wood seemed at least as hard as the maple I bought from Dixie Gunworks and other sources.
How about sugar maples that have been tapped for the sap for a hundred years or so?
