I bought a bunch of 8/4 mixed wood from a guy in South Texas that was in the oil field. The wood came off of train cars that would be spacers for stacked 36” pipe. All of it was rough wood and full of nail. There was quite a bit of oak, hickory, etc. Each board was approximately 6” wide and 1 7/8” thick. I put this wood through the jointer and said, “WOW!” The figuring was really cool. I truly have no idea what it is. I was thinking possibly the heartwood of maple. It is a closed grain wood, not as dense as oak, but plenty hard. I took it to wood craft and asked what they thought it was. The best guess was Ambrosia Maple. I thought I would ask and find out if y’all could identify it.
