Ep 19. Guitar Pickups, Heated Furniture, Water Well Cylinders, Nonconductive Tools

"How It's Made" season 23 episode 19 explores the intricate manufacturing processes behind the creation of guitar pickups, heated furniture, water well cylinders, and nonconductive tools.

The episode begins with an in-depth look at the making of guitar pickups. Viewers learn that pickups are responsible for translating the vibrations of a guitar's strings into electrical signals that can be amplified and heard. The manufacturing process involves winding up to 5,000 individual copper wires around a plastic bobbin to create a coil. The coil is then dipped in a special polymer to prevent interference and sealed in a metal casing. Finally, the pickup is tested and calibrated to ensure optimal sound output.

Next, the show moves on to the production of heated furniture. This segment takes us behind the scenes of a factory where heated massage chairs are made. Viewers learn that the chairs are designed to target specific pressure points and muscles for a more effective massage experience. The manufacturing process involves the use of specialized metal frames, motors, and foam padding. Heating elements are also installed in key areas of the chair to provide warmth and relaxation.

The third segment of the episode focuses on the production of water well cylinders. These devices are used to pump groundwater from a well and store it in a holding tank for later use. The manufacturing process involves the use of high-strength steel that is welded together and then coated with a layer of epoxy paint to prevent rust and corrosion. The cylinder is then fitted with a specially-designed pump and motor before undergoing rigorous performance testing to ensure it can withstand years of use.

The final segment explores the manufacturing of nonconductive tools. These tools are used in high-voltage environments such as electrical substations, where metal tools pose a risk of electrocution or damage to equipment. The show takes us to a factory that produces a range of nonconductive tools, including shovels, wrenches, and hammers. The tools are made from highly durable materials such as fiberglass, carbon fiber, and nylon, and are carefully designed to meet the needs of workers in the field.

Throughout the episode, viewers are treated to fascinating glimpses of the precise and complex manufacturing processes that go into creating these everyday items. From the winding of guitar pickups to the welding of water well cylinders, every step of the process is meticulously documented and explained. The show also highlights the dedication and skill of the workers who bring these products to life, emphasizing the importance of hard work, attention to detail, and innovation in modern manufacturing.
