Electric wheels are also lighter and much more easily moved than wheels that use a heavy flywheel. This has allowed potters greater freedom in sharing their craft since they can take an electric wheel with them and do demonstrations. Torque determines how much clay by weight the wheel is able to center. Commercially available wheels can all center at least 20 pounds of clay, and one can center up to 400 pounds. Something to consider: the power of a big motor is great if you are making big pots, but if you are throwing average-sized pottery, you will rarely want more than 20 to 50 pounds of clay on your wheel at one time. At this point, electric wheels have gone through some changes, including changes in noise levels. Most currently available wheels are not obtrusively noisy, and many make their quiet operation a large part of their sales pitch. Some wheel heads also have removable pins, which allow for trimming directly on the wheel head.
