ABSTRACT:
A method of making a mold assembly for molding inner and outer shells of an equipment shelter utilizes a generally rectangular frame on which are supported a plurality of large flat panels formed of plywood and covered by thin sheets of stainless steel. The panels are separated by rib gaps on the sides and corner gaps at the corners which are closed by temporary, wooden rib and corner patterns. A reinforced plastic laminate is applied to the temporary patterns to form negative molds. When cured, the negative molds are removed from the frame, along with the temporary patterns. A reinforced plastic laminate is applied to each of the negative molds and cured to form permanent rib and corner molds. The permanent molds are positioned in their respective rib and corner gaps to complete the mold assembly.
