ABSTRACT OF THE DISCLOSURE A device for use in the art or craft of molding hollow artistic objects from thermoplastic molding material, such as wax. The molding device includes a frame with a vertical stationary, circular gear rack secured thereto. A crank driven shaft is journaled through the frame in a position concentric with the rack. A yoke-like mold carrier is secured to the end of the shaft for rotation therewith. A mold holder is, in turn, mounted on the mold carrier for rotation about an axis generally perpendicular to the crank shaft axis between the yoke arms of the mold carrier. The mold holder has a shaft projecting through one of the yoke arms of the mold carrier and is secured to and driven with a disc gear, which is enmeshed with the gear rack. As the crank is turned to rotate the mold carrier, the disc gear rides on the gear rack and rotates the mold holder. In operation, a mold in the form of a pair of mating mold halves providing a mold cavity is supplied with molten thermoplastic material, assembled, and mounted on the mold holder. Turning of the crank causes the mold to be rotated on the two generally perpendicular axes and generally evenly distributes the thermoplastic material on the interior of the mold cavity surface as it cools and sets.
