Abstract
The present invention relates to a form for molding building components, such as columns, having a desired size, shape, and surface features from solidifying building materials such as concrete. The form is sculpted from a plastic material such as polystyrene or urethane. The cylinder is hollowed so that the interior of the resulting form has the size, shape, and surface features of the desired building component.
