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 always found propellers really beautiful things . They have a sort of perfect shape .

Um trabalho e tanto num dos maiores transportes do mundo .

😂 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 😂😂😂

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

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.
-
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.

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.
-
Very interesting! Good job.
-
Will toroidal propellers be made/used in the future?
-
What's intersting to me is how even the largest propellers is dwarfed by the shipt they are on, yet they can still move the ship with ease.
-
It must be fun to drive the underwater hull Zamboni!
-
Very little on the actual manufacturing process. I expected a “how it’s made” type documentary.
-
"Curing" is what happens when you have a chemical reaction like 2 part epoxy. Metal casting would be "cooling" ;)
-
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.
-
The bigger, the more fascinating
-
Are there any videos on how they used to make big propellers before computers and multi axis machines?
-
Thank you for sharing the useful video. I watched and get much information. Thank you. Have a nice day!!
-
You are true artists from the casting to the finishing. Cheers to all who make it happen.

12:43 Reminds me of when I built an old 426 Hemi.
