Abstract
The method and apparatus for creating elevator buckets decreases the number of molds required to create a wide variety of dimensional configurations of such buckets by dividing the configurations into families, each of which has at least one dimension in common while each member of a family varies from other members thereof by at least one dimension, the method and apparatus being used to create all members of one family and enables changes to produce different bucket sizes within the same family without removing the mold base used in creating the family from the apparatus.
