I've built fences with the stuff you're referring to, the green comes from the mixture of copper and cyanide (heh heh bad news) that the wood is impregnated with. It kills anything that tries to chew through it


I've done some more research. By using red oak, I accidentally started with one of the hardest woods to use, but oh well. I'll get some cedar or willow as soon as possible. Also, I need to thin out my drill so I can get more rpm's off of it
