Yes sir it is indeed black walnut. We have a lot of it here in northwest Arkansas. We have a lot of red oak too but a lot of that was damaged over the last decade or so by the red oak borer beetle. Lots of standing dead timber when you get into the ozark mountains. I think they took down about 4 trees for my house. Local guy with portable sawmill came over and cut my 8 foot logs into lumber. Also have some cherry from a tornado at my dads place in 2006. Since I've gotten interested in pen turning...I now see all trees (both live and dead) as potential writing instruments!
Well, join to the team mate, I stop driving and let the wife do it as I spend more time looking on the side of the road for trees and searching for something I not seen before, and while you see lots of "writing instruments" in them, I see those, bowls, plates, platters, vases, eggs, tool handles, knife handles and another dozen of things that sometimes I don't know what they are until I see it...!
:biggrin:
Oh... and all about those twisted, curved, awkward trees, branches, limbs that nature produce for us...???? you starting looking and all of a certain you see, table legs/stands, chairs, stools, and a million other possibilities, yeah, you don't know how "bad" you can get mate but, you seem to be on the right path, already...!:wink::biggrin:
Good luck,
Cheers
