36" in diameter, 1 1/4" thick. I think this is white oak, I'm not a dyed in the wool woodworker, so it may be red oak.. In either case, very heavy, 1 1/4 inches thick glu-up. 3 feet in diameter. Black dot is a filler of some sort, may be an imperfection in the wood. I have NOT tried to sand it. Ask questions, but please ask via the telephone. 330-9three4-8231. I do NOT text, ever. But I do answer as long as I hear the ring. I have two (2) of these rounds, your choice. Thanks for looking. Can be picked up in Clark or the Mt Hope flea market on Wednesdays. CALL FIRST
