A potter's table including a rotating pneumatic clay extruder coupled to the potter's wheel. Clay is fed from a vented storage cylinder in centered relation to the wheel past an interchangeable template via a hand valve controlled pneumatic piston and rotatable ram head coaxially mounted within the storage cylinder. An electric foot-operated, proportional speed belt drive, belt tensioning assembly and upper and lower bearing assemblies support the cylinder and potter's wheel in rotative relation to the table and pneumatic piston.
