About three years ago, a magnificent Elm that was at least 90 years old finally died, after agonizing for the last several years. It was in my brothers yard and we decided that it will be honored by transforming it into furniture. We cut it in November 2006, we ended up with 10 logs that ranged in between 2’ and 4’ diameter and about 10’ in lenght. The month after, we hire a portable mill and cut it in several thicknesess and withds. After sitting for nine months in a tent with plenity of air and wind I moved them to my shed. The humidity level in the 1” thick pieces went down to 12%, while the thicker ones are at about 19%. My question is, considering the local humidity in central New Jersey, at what percentage can I start working without risking warpage or end cracks?
As you can see in the pictures, there is about 700 bdf of lumber plus a few turning pieces. So far no warpage and a minimum of end cracks. The piece with the bolt in it cost me $50 in a new blade. It was embeded very deep in the wood and the metal detector did not registered. The blade did.
One of the logs is 4’ in diameter. To big for the portable mill, and to heavy to bring it to a bigger one. We spend many hours tryng to cut it in half, we even put a 20 ton jack in a cavity that we carved. So far it is still sitting in the ground. We are waiting for the spring to give it another try. Any ideas are welcome. No explosives please.
