I'm Polish and I find this propeller smooth enough
Really?
@@smellygrapefruit8685 Oczywiście
XD
Smooooth...!!!!
Are you a plumber aswell?
Everyone don’t be fooled. This prop is only the size of a bathtub boat. Hammond is just that small.
Kay’shots whoosh
@@Kayshots why u have to ruin everything
Well as news company always compare things with “As big as a bathtub” or “Football fields” That’s what i tried to make a joke on. So yeah. R/Wooosh on you guys instead..
@@Kayshots r/sure
Kay’shots nah you’re just a bit shit
Hammond makes everything look much bigger lol
Hahahahaha
Maybe that is why he needs someone to Help "polish" the "giant propeller"... LoL
True😂😂😂I love the guy and I'm wanna invite him to film my house so it will look bigger😂😂😂😃
Wow
Bahaha Jeremy is that you?
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.
I feel like this show will only emphasize Hammond's small stature. Or rather use his stature to emphasize how BIG the stuff is
That's probably why they picked him for the show
Hes like 5'7 hes not that small
@@robertjusic9097 that's small
@@robertjusic9097 basically Peter Dinklage
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
I love that it is referred to as artistry. And not just work or a job.
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!
Thank you for this information, i was searching where the propellers were made
if the product has actual application, its not art. its craft. that guy's a craftsman.
Those dudes pouring in the uniform... I could totally see Minions doing it and Hammond is their master 😂😂😂
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.
I love that he is wearing a scarf, complaining how hot it is...
Reminds me of the book, "Hunt For Red October" when they were screaming; "WE'RE CAVITATING!!"
reported for misleading title. "Richard Hammond's Big"
(joke, obviously)
🤣🤣🤣
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.
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
Human engineering is such a great thing.
That sanding machine is very awesome.
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
amazing clear and informative
This is really cool! I love watching whatever Hammond does but I find this particularly cool and interesting.
"Top secret metal alloy"... revealed in the previous CZcams video.
I am a simple human being... When I see Hammond i click...
Wow its incredible how much work goes into prop toy propellers to allow richard hammond to stand on them
Gotta give Richard props for doing this.
He’s the David Attenborough of engineering
Nothing more funny than seeing an excited hamster 🐹.....🤣🤣🤣🤣
Amazing work
“The worlds biggest tickling stick” 😂😂😂
“It’s really really hot” as he stands there wearing a scarf.
Hammond makes a great documentary keep up the good work and the grinders and other people that make the propellers are all crafts people
im even amazed the cast even look good before the finishing
Cavitation is such a simple concept but you fail to come close to an adequate explanation.
Hammond must have the coolest safety helmet ive ever seen.
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"? 🤣
Haha - of course they’ve both got the same pitch. Think you are confusing pitch with hand

@@optimist3580 yip. That's the prize for not being a native speaker... 🙄
That animation has multiple issues! Pretty sure cavitation doesn't approach from behind either 🤪
@@Bbonno Bet you are wrong about that. The lowest pressure is behind te screws and blades...
@@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.
Everyone just comments on how small Hammond makes propeller look big. I'm amazed they haven't built a machine to make this work. Still by hand... Crazy
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.
More and more factories use large scale CNC machines for this job.
I love this guy
Really beautiful 👌
“Energy I’m giving nothing but energy “ -pop smoke 2020
That grinding with basicly an excavator. Crazy
I like how in the prop animation one was pushing the boat forward and the other backward
I like how this has already been pointed out by other people.
i like how the title is "Richard Hammond's Big"
Man even the bucket looks bigger near Hammond !
3:21 The worlds biggest tickling stick 🤭
Richard ❤️
TONIGHT: Richard polishes a 5hp motor propeller
Me:reads in title, Richard Hammond's big
Me:now let me tell you what's wrong with that sentence right there
Hammond is that kind of guy, that does backflips under the bed
Is there a longer version off this video?
4:04 That's one hell of an Allen screw.
Give him PROP, this is impressive
In part two Hammond polishes the shaft!
"Only becomes molten when it reaches 1200 degrees..."
Oh that's hot but surprising
..."Celsius"
Oh damn that's REALLY hot nevermind
Celsius is standard in any country
Why you american capitalist noob
@@010falcon it's the American way, gotta change things for no reason
@@help3102 That doesn't make sense in this case, they haven't changed from the British imperial system they started with. Though SI is already standard in US industrial/commercial fields.
@@010falcon "Capitalist noob." I'm glad you got that out of your chest
@@MrDJAK777 it slowly finds it's way through the public, too.
I've been used to have to convert from US imperial to metric myself, while in the past couple of years, many media, especially youtubers go ahead and just add both measurements. It's still a slow process, but eventually, even the US will pick up metric.
4:29 ooh that’s my hometown :o
Last time hammond done this. He got a job on top gear 🤣🤣
These videos are like travel cooking shows for boys
World biggest tickling machine. That good one..
I read the title said: "Helps a Polish propeller"
Hes becoming James May with all the engineering shows he does.
Nice video hamster
Imagine being a huge metal blade weighing tons but being destroyed by bubbles
Legend says Richard is in the comment section
Did he work the shaft too?
These propellers can cut great white sharks in half.
The worlds biggest tickling stick😂
When did he help polish it exactly? I must have missed that part of the video
they called James May to do that, it's a precision job after all.
2:46 f18 joystick i see. Very nice
I polished my propeller this morning.
"10's of milimetres"... you mean centimetres?
He said tenths of millimeters. Party adjourned, 12 likers
What he means by tens of millimeters is a tolerance of 0.1/ 0.2 ... mm
@@u1zha - No he didn't, he clearly fked-up and said 'TENS' ...... are you his mum???
Why in gods name would you thumbs down this video ? Good work Hammy ;)
Dave Johnson because he didn’t help polish anything like the title promised
I was eating to see the Polish person in the video, but all I saw was a propeller being being polished .
Why isn’t the show available on Discovery+? Put it on the app.
MMG propeller! :D
@01:00 - Well, I thought that went down really well Richard...... like a lead balloon!!!
Would have been interesting to see how they check for balance.
i wanted to see the machining side of it. like the tapered bore
what is that casting process called? when it is poured into the mould?
All fun and games till its in water then for some reason it becomes terrifying
Amazing ! روعة
And this is why the titanic sunk Richard helped 😂
Would rather look at new and old propellers than go to an art gallery.
At the beginning with the hats on I thought he was Ironman
RICHARD HAMMOND’S BIG WHAT!?!?!?!?
up next: richard helps polish a giant shaft.
I may be the only one but I miss Richard getting excited about motorcars, motors and exhaust components. I guess this will have to suffice?
Is that propeller held on with just a grub screw
That polishing machine reminds me of the manned robots in avatar
My friend once got arrested for polishing his propeller in public.
1:01 this dude reminds me of john oliver
Did he also get to polish the shaft?
Hammond compensating for his size
I'm not sure how valuable the dust is, but do they collect it ?
Crazy, so, grinding with that machine, a simple operator error might cause a large dent in a million dollar propeller?
Shouldn't he be wearing a mask when he was in the polishing room even the guy operating the crane with the polisher on it had his mask off... that look like a lot of metal alloy dust being sent up into the air
Dane Endly it's so heavy, it just falls to the floor instantly
@@niklasalmaas6369 that plus the torque/ grit on that machine definitely helps. Probably makes chips compared to a 2x72”
Wonder if that will fit on a Boston Whaler??
Do they reuse the scrap metal shavings?
Chuck Norris drinks one of these every morning
Wow years of experience does not equal a couple of hours of experience. Who would of thought...
what about the building of the mold??
No one:...
The one polish worker: KURWAAAAAA!!
I feel like I'm watching the Borrowers.
