Abstract: A model and die system includes a working quadrant having an upper flat surface. Pin-receiving tapered bores are formed in the upper flat surface and a thin metallic foil covers the bores. Cast teeth are supported by the working quadrant and each cast tooth has at least one tapered pin depending from it. Each pin includes a tapered main body that matches the taper of the tapered bore, a reduced diameter section of the same taper that accommodates torn or ruptured foil, an annular ramp section that sharply crimps the foil about the entry of the tapered bore, and a tapered rim that matches the taper of the tapered bore to lock the pin into its fully seated position.

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.
