Hamilton County came to us to replace the existing seating in the Cincinnati Reds Stadium. The current seats were not made to correct specifications and were failing. The seats were cracking and falling out of the metal brackets. I quickly realized the issues and we made some design changes. There were 8 new molds made to replace the seating. The widths are 19",20", 21" and 22" of the Seat Pan and Seat Back. The new molds are all CNC machined from aluminum billet. The Reds had a problem fastening the seat pan to the metal brackets. The 1/4-20 nut would strip out of the part so we came up with idea of molding a wingnut into the part and using air cylinders to push it up into the part during the molding process. It worked perfect and the whole project was a huge success. It saved Hamilton County over $2 million dollars.
