Its the specialty market your looking for.I mill and my buddy who mills can get 3$ and up a board foot for Black walnut. The real money is in the Burls/ root wad, and crotches that make fiddle back grains premo stuff that fetches way way more.
Most sawyers that deal with these kinda woods use metal detectors and are able to cull or work around the inperfections and it is possible to find rocks of diffrent sizes in the burls... thats part of doing buisness.
When and if anybody taps into this market it can be profitable.
People/companys ship these burls/wood over seas! The person making the larger money is not so much the tree/home owner but the sawyers and middle man that deals with you. In the end that tree may make a bunch of people some really good money. Depends how large the tree is 5ft? 8ft..even 10 and up!!
My other buddy specializes in this trade and will pay home owners several thousand dollars for a quality tree. He cuts the tree down digs out the root wad,loads everything on a truck,cleans up. In some cases he hikes in digs masive wads out by hand sometimes taking 2 days and then has a helicopter
do a GPS pick up takes it to the veneer mill and still makes money on it. I havent seen him in 6 months but he's always scouting the west coast for trees neighbor hoods to timber lands was even setting up a veneer mill last we talked.
This may not be realistic for you in your area but it is in mine and i would LOVE to have all YOUR Black Walnuts,Pepperwood,Cherry,Madrone...........
