Ep 12. Barber Chairs and Sewage Pumps

In season 21 episode 12 of How It's Made, viewers are taken on a behind-the-scenes look at the manufacturing process of barber chairs and sewage pumps.

The episode starts off with the manufacturing process of barber chairs, which involves several intricate steps. First, viewers get to see the welding and shaping of the chair's frame, which is typically made from metal. Next, the chair is covered in foam and then upholstered in high-quality leather or vinyl - the materials for which are chosen based on the chair's design. Viewers also get to see how the chair's adjustable height mechanism and footrest are assembled, along with the chair's headrest and armrests. Finally, the completed chair is tested before it is packaged and shipped to its destination.

Following the coverage of the barber chair manufacturing process, viewers are shown how sewage pumps are made - an entirely different process that involves a series of different steps. Sewage pumps are responsible for pumping out wastewater and sewage from homes and businesses, which is why their construction and quality control are of utmost importance.

The episode delves into how sewage pumps are built from the ground up, starting with the motor's fabrication, which involves the assembly of the rotor and stator. This is followed by the installation of the impeller, which plays a crucial role in moving the wastewater through the pump as efficiently as possible. The body of the sewage pump is typically made of durable materials like cast iron, which are designed to withstand the corrosive properties of wastewater over time. The pump's float switch is also installed to ensure that water levels are monitored and controlled to prevent overflows.

Throughout the episode, viewers get to see how the manufacturing machines involved in making both barber chairs and sewage pumps work. They also get an appreciation for the many skilled workers and technicians who help bring these products to life. Additionally, the episode highlights the importance of quality control and product testing, not only for the safety of consumers, but also to ensure that these products are built to last.

Overall, How It's Made season 21 episode 12 offers a fascinating glimpse into the world of manufacturing and the intricate processes behind the creation of two essential products - barber chairs and sewage pumps. Viewers come away with a newfound appreciation for the skilled labor and technologies involved in making these products that many of us take for granted in our daily lives.
