Ep 24. Screwdrivers, Rubber Track Loaders, Physician Scales, Carbon Fibre Baseball Bats

In season 6, episode 24 of How It's Made, viewers are taken on a fascinating journey through the production processes of four very different products: screwdrivers, rubber track loaders, physician scales, and carbon fibre baseball bats.

First up are screwdrivers. Viewers get an inside look at how the blades and handles are manufactured separately before being assembled together. From forging and shaping the blades to heat treating and coating, the process of creating each screwdriver involves multiple steps and a variety of specialized machinery.

Next, the episode explores the production of rubber track loaders. These heavy-duty machines are used for construction and other heavy-duty applications, and their manufacturing process is just as robust. The episode breaks down each component of the loader, from the engine and hydraulic system to the tracks and bodywork.

Moving on to physician scales, viewers learn how these important medical tools are made. Precision is key in the creation of these scales, which typically feature both traditional mechanical dial displays and digital readouts. The episode follows the manufacturing process from the initial design stage to the assembly and testing of the finished product.

Finally, the episode finishes off with a deep dive into the production of carbon fibre baseball bats. These advanced sporting goods are made by layering carbon fibre sheets and combining them with a resin that is cured under high pressure. The process is complex and involves carefully laying out each layer of fibre by hand. Viewers get to see the steps involved in making both the barrel and the handle of the bat, as well as the final steps of finishing and sanding the product.

Overall, How It's Made season 6, episode 24 offers an engaging and informative look at the manufacturing processes behind four very different products. Through detailed explanations and high-quality visuals, viewers gain a deeper appreciation for the level of skill and precision required to create each item.
