Abstract
A model and die system has a working quadrant of parallelepiped construction and a opposing quadrant of the same construction. The working quadrant has an upper flat surface disposed in confronting relation to a lower flat surface of the opposing quadrant. Pin-receiving bores are formed in the working quadrant and mounting members depend from the opposing quadrant. Each cast tooth supported by the working quadrant has a pin depending from it and is fully seatable against the upper flat surface. Each cast tooth mounted on the upper flat surface is secured to a mounting post that depends from the upper flat surface. In a first embodiment, the quadrants are held in spaced apart, adjustable vertical relation to one another by a pair of parallel guideposts. In a second embodiment, an articulated hinge performs that function. In a third embodiment, a semicircular base opposes a semicircular top member.
