For those wondering, the golden looking metal is called Aluminium Bronze, it's currently the go to choice for its toughness, corrosion resistance, and ability to prevent much of the buildup that other materials can experience.
-
😂 I was interested in seeing how propellers are designed, build and installed with all the science and technology behind it … And I find myself watching 10mins of underwater cleaning 😂😂😂
-
I always found propellers really beautiful things . They have a sort of perfect shape .
-
Very little on the actual manufacturing process. I expected a “how it’s made” type documentary.
-
Beautiful footage, too bad it doesn't always coincide with the dialogue. I'd think blades on variable pitch props could rotate 360 degrees (they can't) if I hadn't worked on them.

Worked for LIPS in Brazil and that time we did a giant one made by CuNiAl!!! Great Time!!!! 55Tons ready to use!!! That time the polish and the machine the blades was by hand. Holes defines the thickness and machining til the holes vanishes. Was incredible, even a 55Ton propeller!!!! 70's

"Curing" is what happens when you have a chemical reaction like 2 part epoxy. Metal casting would be "cooling" ;)
-
It must be fun to drive the underwater hull Zamboni!
-
I liked the vid first yay🤩🤩🇸🇪👑

While working at Pier 71 in Seattle, I watched a giant bronze ship propeller come to life. The whole process took three months. Pour day day was quite exciting. That’s a lot of molten metal. It took weeks to cool.

Um trabalho e tanto num dos maiores transportes do mundo .
-
That's one of the most fascinating things I've ever seen on video. A ship's propeller in motion under the water. And in such crystal clear water too.

12:43 Reminds me of when I built an old 426 Hemi.
-
Greetings from the BIG SKY. Big brass propellers!
-
My old boss worked in a foundry in Serbia. One of the things they made were ship propellers. They were sand castings. It was a one shot deal. If you screwed it up, you had to start all over again.
-
Good job‼
-
You completely skipped the most crucial part of propeller manufacturing: Balancing and Surfacing, which is done by super rare experts and can significantly change a propeller's efficiency.
-
Very interesting! Good job.
-
I always wondered how the propellers were made. And finally I have found the right video regarding it.
-
The propeller, designed by Brunel, on the SS Great Britain, was only 5% less efficient than these.....
