My wife is a principal in an elementary school and need a spinning wheel for a system they use in school for grouping kids in a learning, motivation and reward system. I was of course designated as lead builder for this. Wheel is 4 feet across and stands about 7 feet tall. Kids in school love getting to spin wheel so is a success. Was fun building something that makes kids happy. The mutt is my Murphy Man, he wanted to be in photos. 128 lbs of pure baby.
