I guy that I work with heard me talking about turning wood on my lathe and said that he knew where I could get some black walnut wood. Of course I was intrested...anyway....he told be there was some in his backyard that I could have and has been there for several years. I went to look at it and it is a tree trunk about 8 feet long and at least 35-40 inches round. WOW!! It has been laying there ever since it was cut down several years ago and even all the bark has been weathered away. I don't even think my 16 inch chain saw could do anything with this. I will have to get help cutting it up. However I'm now wondering if it could have rotted in these few years that it has been down and left outside? It feels very solid.
