I'm happy that they explained Cavitation at the end. And the way he said that it's artistry and sculpture will never be seen, was dramatic and hard hitting.

[@bartman8876]

I love that it is referred to as artistry. And not just work or a job.

[@huey-fan8335]

Fun Fact: The Factory for the Props is the Mecklenburger Metallguss, based in Germany....it is about 80 km far away from the shore, so the Propellers have to be transportes either by Trucks or by Train to the customers!

[@herrkluger]

Thank you for this information, i was searching where the propellers were made

[@TheGnarTube]

2 men in the world are fit to be clean-shaven the rest of their lives. One is cumberbatch, the other is hammond. Good show anyway

[@random_stranger185]

if the product has actual application, its not art. its craft. that guy's a craftsman.

[@TallTav]

I work in the foundry of a large coppermill, and I'm actually the only grinder they have for the thousands of castings we put out a month... I wish we had one of those machines, because everything i do is 100% handwork due to fine tolerances. This video was interesting to me in the best way.

amazing clear and informative

[@neonviking8447]

reported for misleading title. "Richard Hammond's Big" (joke, obviously)

[@quincekreb6798]

🤣🤣🤣

[@stephendoherty8291]

The submarine designers had the same issue and it also created noise to help their enemy hunt them, so they made propellors with more vanes so it could turn slower but generate the same torque and some surrounded them in an enclosure to drive the water entering the vortex faster. Strange ship builders looking for fuel efficiency and not speed don't consider this

[@yammmit]

This is really cool! I love watching whatever Hammond does but I find this particularly cool and interesting.

[@65elcamino283]

Reminds me of the book, "Hunt For Red October" when they were screaming; "WE'RE CAVITATING!!"

That sanding machine is very awesome.

[@lostmymarbles9151]

Gotta give Richard props for doing this.

[@BalwinderKaur-wt7ux]

Amazing work

[@srh2301]

Haha, the animation at 4:34 is wrong. The two propellers have got the same pitch, but turn in different directions. Is the ship supposed to turn on the spot? Or is the left propeller a magic design, which sends the thrust backwards although it turns "Full Astern"? 🤣

[@optimist3580]

Haha - of course they’ve both got the same pitch. Think you are confusing pitch with hand www.steeldevelopments.net/pages/how-props-work

[@srh2301]

@@optimist3580 yip. That's the prize for not being a native speaker... 🙄

[@Bbonno]

That animation has multiple issues! Pretty sure cavitation doesn't approach from behind either 🤪

[@hamstrtj]

@@Bbonno Bet you are wrong about that. The lowest pressure is behind te screws and blades...

[@Bbonno]

@@hamstrtj nah, that's where the water is moved towards. The low pressure is ahead of the propeller giving cavitation damage on the leading edge.

[@indicus9075]

Wow its incredible how much work goes into prop toy propellers to allow richard hammond to stand on them

[@allyourcode]

IIRC, the US Navy has figured out how to shape propeller blades to significantly reduce cavitation. This helps keeps submarines undetected. When subs are out of water (before launch), they cover the props to prevent people from copying their winning design. Science for the win.

[@GrahamWalters]

A ship is recognisable by the noise it's propellor makes, no two are the same, it's called a ships signature, and submarines use it to indentify hostile ships

[@darrylrajamae4855]

Hammond makes a great documentary keep up the good work and the grinders and other people that make the propellers are all crafts people

It seems like a machine would be unnecessary in quality over quantity products like this. They make maybe one a week at most. Besides, a machine this size would cost quite a lot i would think.

Tens of mm is not that tight tolerance. By hand, sure, with a lot of surface area, but that end product looks really rough. It'll all be worn smooth anyways by cavitation, though
