Transferring files and ran across this. Quite neat I thought. However. There is ALWAYS a however. However, I would NOT recommend using pressure treated wood to make one of these. There's a piece somewhere on the web about using pressure treated wood in buildings used to house animals, and the attendant problems that causes. People already have enough problems with wood they have reactions to without adding to it by using stuff like this for furniture, or where you'll have close physical contact with it. Other than that, I believe this could be a good 'training film' for beginner woodworkers. http://www.youtube.com/watch?v=aarbx-3Qx8M
