The cooper may have had a base, but he travelled around to where his skills for churn and barrel making were required. The exact nature of the work depended on location, connecting with land or sea. He might even make buoys at sea. The need for him was diminishing with factory processes, and he overlapped with the wheelwright in terms of skills and processes.
