Ep 9. NASCAR Car Bodies; Hurley Sticks; Tube Power Amplifiers; Thermal Coffee Pots

"How It's Made" is a fascinating show that takes viewers on an inside look at how everyday objects are manufactured. In season 16, episode 9, we are taken on a journey to see the process behind NASCAR car bodies, Hurley sticks, tube power amplifiers, and thermal coffee pots.

First up, we dive into the world of NASCAR and see how these highly specialized race cars are built. NASCAR car bodies are crafted in a very specific way to meet the unique demands of racing. The process begins with a wooden template that is used to shape the car's body. From there, a mold is made, and fiberglass is laid on top. The fiberglass is then coated with a special resin and left to dry. Once the composite material has hardened, it is removed from the mold and any excess material is trimmed away.

Next, we take a look at Hurley sticks, which are used in the sport of hurling, a popular team sport in Ireland. Hurley sticks are made from ash trees and are carefully selected for their strength and durability. The sticks are then cut to the desired length and shape, and any bark or knots are removed. The sticks are then sanded and polished before a coat of varnish is applied.

Moving on, we explore the manufacturing process behind tube power amplifiers, which are commonly used in audio equipment such as guitar amps. Tube power amplifiers consist of a series of glass tubes that amplify the signal of an electrical instrument. The tubes are created by first blowing a glass tube into a bulb shape. Then, a metal filament is inserted into the tube, and a vacuum is created to remove any air. Once the vacuum is complete, the tubes are heated to a high temperature, which causes the filament to glow and produce an electrical signal.

Finally, we take a look at thermal coffee pots, which are designed to keep coffee hot for long periods of time. The pots are made from stainless steel and are double-walled to provide insulation. The manufacturing process begins with the creation of a stainless steel shell, which is then filled with a special insulating foam. The foam is then covered with another layer of stainless steel before the pot is polished for a sleek finish.

Overall, this episode of "How It's Made" showcases the diverse range of manufacturing processes that go into creating everyday objects such as NASCAR car bodies, Hurley sticks, tube power amplifiers, and thermal coffee pots. Through careful attention to detail and skilled craftsmanship, these manufacturers create products that meet the highest standards of quality and performance.
