Modeled after a real Tennessee grist mill, you can have a little working water wheel (about 12" in diameter) WITH a grist mill -- use a submerged water pump to re-circulate the water and make the wheel turn. It's perfect for the garden or flowerbed. Full size patterns are provided for curved parts, a list of the materials you need to build the unit, plus step by step instructions for building, and even a few photos. Finished size is 28" tall, by 53" wide, by 22" deep.
