On this episode of "Shop Class," the teams are challenged with taking an iconic school item and transforming it into a skate park obstacle. Each team is given wood, steel, and metal tubing to incorporate into their obstacle. After three full days of designing and building, a pro skateboarder stops by "Shop Class" to skate each of the teams' skate park obstacles. Three teams compete but only one team will earn a spot in the semi-finals and be one step closer to the championship, the title of "Shop Class" Champs, and take home an epic grand prize.
