ABSTRACT:
A method and apparatus for fabricating columns, wherein the apparatus includes a column fabricating assembly and a column extractor. The column fabricating assembly includes a unitary column mold and a mold support assembly. The unitary column mold is reusable and is fabricated specially for the task of fabricating a column therein. Uncured column materials are placed into the unitary column mold and the unitary column mold is enclosed in the mold support assembly. The uncured column materials cure, and thus the column is formed, while the unitary column mold is encased in and spun by the mold support assembly. The unitary column mold is removed from the mold support assembly with the column therein. The column extractor is used to extract the column from the unitary column mold; the unitary column mold is secured by the column extractor and the column extractor pulls the column out of the unitary column mold.
