Ep 38. Drill Bits, Photo Booths, Stamps #1, Stamps #2

How It's Made season 4 episode 38 takes a look at four very different products: drill bits, photo booths, stamps #1 and stamps #2.

The episode begins with an in-depth look at how drill bits are made. Viewers will see the process of creating a steel rod from scratch, which is then heated and molded into a specific shape. The drill bit is then sharpened and polished before being treated with a special coating that prevents rust and wear. Finally, the drill bits are packaged and sent out for sale.

Next up are photo booths, a modern take on a nostalgic concept. The episode shows how these booths are assembled, starting with the metal frame. The electrical components are then installed, which power the camera and printing system. A custom curtain is added, as well as a comfortable bench for users to sit on. Finally, the booth is tested to ensure it works as intended.

Then, the episode moves onto the manufacturing process for stamps, specifically the first type of stamp. Viewers will be taken through the creation of the stamp's rubber base, which involves mixing different chemicals and dyes to create the desired color and texture. The base is then molded and cut to size before being mounted on a wooden block. The image for the stamp is then laser cut into the rubber and mounted onto the block. Finally, the stamp is tested before being packaged and shipped.

Lastly, the episode explores the creation of the second type of stamp, which is made using a different process. Rather than using rubber, these stamps are made from pre-inked pads and a plastic substrate. The pads are made by mixing pigments with a gel-like substance before being molded and cut to size. The plastic substrates are also cut to the correct shape and size before being pressed onto the pads. The image for the stamp is then laser etched onto the plastic, with each color being added layer by layer. Finally, the stamp is tested before being packaged and shipped.

Throughout the episode, viewers will be provided with interesting facts and insights into each product, including their history and how they have evolved over time. The episode provides a fascinating insight into the manufacturing process for these everyday items, highlighting the intricate detail and care that goes into their creation.
