If there is one thing that we like seeing around here, it’s cool videos that highlight the ways mankind has developed to machine metals into the shapes and sizes that are needed for different jobs. When it comes to cars, some of the neatest looking parts are inside the cases of superchargers. There’s the cool looking straight or twisted rotors of a Roots style blower and then there’s the hypnotic screw supercharger that takes the root concept and makes it more efficient and effective. Now, these designs were not initially developed for use on engines and it took decades and decades to adapt them to help making horsepower. The screw and Roots blower were designed to be used as air pumps for things like blast furnaces, mines, and other occupational and industrial needs.
Turns out, they are still used heavily in these occupational and industrial applications and that means that they need to be produced in a massive range of sizes. That is exactly what you are going to see in this video. You’ll see rotors and screws that look like something that might be found on a big engine and then you will see stuff that seems to belong on a locomotive, ship, or other mondo spot. Hell, look at the photo above and this guy checking a set of screws that are bigger than he is!
This is a fun and relaxing look at some awesome machining. Enjoy.
