ABSTRACT:
An index bar is secured to a machined and leveled surface of a base. One side of the bar is machined to be contacted and to act as a buttock plane. The bar has a series of in line holes positioned for lengthwise indexing. A second index bar, secured to the base, has a series of matching holes and the bar is positioned parallel to the buttock plane. The index bars are used for alignment for scribing header locations on the base. Headers, contoured with respect to the base surface and with respect to the buttock plane, are formed and while on the scribed line and while contacting the base and the buttock plane surface, are secured to the base. The secured headers are vertically aligned and held in that position to provide the critical lines for forming a master model.
