How It's Made Season 22 Episode 8 Office Chairs, Vinobrews, Reconditioned Sander Drums, and Lithographs

In season 22 of How It's Made, episode 8 explores the manufacturing processes of four different products: office chairs, Vinobrews, reconditioned sander drums, and lithographs.

The episode begins by showcasing the creation of office chairs, starting with the production of the chair frame. The frames are made through a process known as extrusion, where long pieces of aluminum are forced through a shaped opening to create a hollow tube. The tubes are then cut into the appropriate length and shape for the chair frame. The next step is to add the chair's various components, such as the base, casters, and armrests. The chairs are then coated with paint or other finishes before being shipped to their final destination.

Next up, the episode explores the world of Vinobrews, a hybrid drink that combines beer and wine. The production process for Vinobrews starts with brewing a batch of beer, which is then mixed with wine. The mixture is then transferred to a fermentation tank, where it will ferment for about a week. After fermentation, the Vinobrew is carbonated and bottled. The final product is a unique blend of flavors and aromas that can be enjoyed as a standalone drink or paired with food.

The third product featured in this episode is reconditioned sander drums. These are machine components used in sanding wood or metal, and they require periodic maintenance and repair to keep them in working condition. The reconditioning process begins with disassembling the drum and separating the rubber surface from the metal core. The rubber is then stripped off, revealing the worn metal surface beneath. The metal core is then cleaned, repaired, and polished to remove any dents or scratches. A new layer of rubber is then applied to the core, and the drum is reassembled and tested for accuracy.

Finally, the episode explores the production of lithographs, a type of printmaking process that involves creating a design on a flat surface using various materials, such as stone, metal, or even plastic. The lithograph process starts with a drawing or design that is transferred onto a flat surface using special ink. The surface is then treated with a series of chemicals to create a printing plate. The plate is then run through a printing press, where the design is transferred onto paper or another suitable material. The lithograph prints created using this process can be highly detailed and are often used in art prints or reproductions.

Overall, this episode of How It's Made provides a fascinating glimpse into the manufacturing processes behind four very different products. From the precision and engineering required to create an office chair to the artistic finesse used in lithography, viewers are sure to learn something new about the world of manufacturing and production.
