Determine Size of Pottery Wheel Head
Before purchasing a pottery wheel you should also determine the size of the equipment you want to use. Most potter's wheels come with either an 11-inch, 12-inch, 13-inch, or 14-inch wheel head. This is sometimes called the centering wheel. The size of the head will determine how much clay you'll be able to center. For example, most 11-inch potter's wheels only let you center a small amount of clay, say, up to 25 lbs. Also, many of the 11-inch wheels are actually desktop wheels. This type of pottery wheel is strictly for the most basic of beginners that don't have a lot of floor space.
Ideally when looking for a pottery wheel for sale you want to choose one with a 13-inch or 14-inch reinforced aluminum head.
Get the Right Horsepower for the Used Pottery Wheel
The horsepower for a pottery wheel ranges from 1/4 HP to a 1 HP motor. The more horsepower, the more clay you can center and the more powerful the overall pottery wheel will be. If you're a beginner you may want to choose a pottery wheel with a 1/2 HP motor. More advanced potters may choose wheels with 1 HP motors.
