Heavy Duty Pottery Wheels are made to throw a lot of clay and have maximum power capabilities for the most demanding potters. They are strictly for professional use or for anyone who wants to throw a lot of clay with the most torque. These wheels also include certain features and options that cannot be found in any other wheels (budget and standard). Because they have the most power, they also cost the most so it is important to consider the average weight of clay you are willing to throw at one time. Having a big and powerful motor is great and all for making big pots but if you are only throwing average-sized pots (20-50 pounds), it may be better to consider getting astandard pottery wheelinstead.
