Your welcome Rover Brewer. Hickory would be a good choice too. I have been to every lumber yard or hardware that carries the red oak within an hour and a half of where I live. Have got about 6 keeper 1/4 inch ones. The other I bought thicker and will cut them down to 1/4. If you have any lumber mills around you, they may be of help for you. I have one here. My neighbor down the street is getting me some hickory, hard maple, and walnut. He's a supervisor at the mill, so that doesnt hurt either.
But if you do have some mills near by, I'd go to them, tell them what I was doing, and just see. My experience so far, is that once they see what your doing, they become interested, cause for most they have an interest in woodworking too.
