Ep 9. Armored Vehicles, Tension Fabric Buildings, Rowers, Sculpture Enlargements

In season 18 episode 9 of How It's Made, viewers are taken on a journey into the manufacturing process of four different products: armored vehicles, tension fabric buildings, rowers, and sculpture enlargements.

The episode begins with a look at how armored vehicles are made. The process begins with steel sheets being cut and bent into the necessary shapes for the vehicle's body. The sheets are then welded together, and the vehicle is fitted with bullet-resistant glass. The vehicle is then sandblasted and painted with an outer coating that is scratch-resistant and rust-proof. Finally, the vehicle is tested for safety and durability before being delivered to the customer.

Next, the show examines the construction of tension fabric buildings. These structures are made using a combination of steel and a specially-designed fabric that allows sunlight to filter through while blocking harmful UV rays. The steel frame is first built and bolted into place. Then, the fabric is stretched over the frame and tensioned into place. The building is finished with doors and windows, as well as an HVAC system that controls the temperature and humidity inside.

The third product covered in this episode is rowing machines. These machines are designed to mimic the motion of rowing a boat on water, providing a full-body workout that is low-impact and easy on the joints. The process of building a rowing machine starts with welding the frame together and attaching the seat. Next, the wheels and chains are installed, and the machine is fitted with a flywheel that generates resistance. Finally, the machine is tested for safety and performance before being shipped to the customer.

The final product showcased in this episode is sculpture enlargements. These are exact replicas of existing sculptures, blown up to a larger size for display in museums, art galleries, or public spaces. The process of creating a sculpture enlargement begins with a 3D scan of the original sculpture. The scan is then used to produce a foam model, which is carefully carved and finished by hand. The finished model is then coated with a special material that hardens into a durable shell. The shell is then used to make a mold, which is filled with a durable, lightweight material to create the final replica.

Overall, season 18 episode 9 of How It's Made offers a fascinating glimpse into the manufacturing processes behind some very different products. From armored vehicles to rowing machines, this episode showcases the skill and expertise required to make some of the world's most complex and unique objects. With detailed explanations and stunning visuals, viewers will come away with a new appreciation for the work that goes into creating the things we use every day.
