Abstract: A concrete post molding device is disclosed for simultaneously forming a plurality of uniform, reinforced concrete posts. The device includes a housing containing an annular chamber defined by a fixed horizontal first plate having a central cylindrical pipe and a spaced concentrically arranged sleeve vertically supported thereon. A plurality of circumferentially spaced radial fin members are connected with the pipe for dividing the chamber into a plurality of circumferentially arranged vertical compartments, and the first plate contains a plurality of openings arranged opposite the compartments. The concrete post molding device is characterized by novel reinforcing rod suspension and tensioning apparatus. An annular ring is connected with the upper portion of the pipe and includes a plurality of first chucks for gripping the upper portions of the reinforcing rods. The lower portions of the rods are suspended in spaced relation in the compartments and extend vertically through the first plate openings.
