It's actually not that hard, probably the biggest difference is you build a maching solution around the job rather than building the job around a machining solution.

Is there a forge near by? 800 TONS of steel... screams "Recycle ME!" Ps. I'm trying to figure out, for a personal project, where large forges/sources of steel are and eventually QUALITY. Examples: Seattle(?), Pittsburgh, China(Beijing), England(London?)
I can't fathom how that crankshaft alone was forged and machined to no doubt extremely precise tolerances in the 1920s. It is a piece of mechanical art ❤
For those who could not understand the name of the engine, it's "Sir William Prescott." "The ‘Sir William Prescott’ and ‘Lady Bessie Prescott’ engines are inverted marine-type triple-expansion engines. They were built by Worthington Simpson in Newark-on-Trent and named after the Chairman of the Metropolitan Water Board and his wife. The engines were installed to each pump 12 to 19 million gallons of drinking water per day to reservoirs in North London for the supply of fresh water to The City, Central, East and West London. The triple-expansion engines stand 62 feet tall and weigh 800 tons. They have a top speed of 25.4 revolutions per minute and generate 1008 water horsepower. Each engine has three double-acting cylinders known as the high, intermediate and low-pressure cylinders. Each measures 29, 54 and 86 inches, respectively. In service days, steam entered the high-pressure cylinder at 200 pounds per square inch. The pressure has been reduced to 60 psi for operation in preservation. The remaining two cylinders reuse the steam before being exhausted into a separate condenser which produces a vacuum. A bank of Coal Fired Boilers in an adjacent boiler house originally produced the steam. Steam is now generated by a small gas-fired boiler. The crank webs are set 120 degrees apart, providing smooth, balanced operation to the engine motion and a steady discharge from the pumps into the water mains. There is no point in the engines’ rotation where no pump delivers water. The triple-expansion engines were commissioned in 1929 by the Minister of Health, Arthur Greenwood and ceased operating in 1980 when Kempton Park became an electric pumping station. The ‘Sir William Prescott’ (No. 6) & the Lady Bessie Prescott (No.7) triple-expansion engines are mirror images of one another."
In the US Navy I was a boiler technician and we had to use slam hammers in order to turn those big ass nuts. There's no other way and it worked but it took a lot of effort

This engine was used in the '57 A Night To Remember. Because the engine was operating as intended, filming area was limited. This engine has been used many times in film and tv. Ex:poirot
If you want the maths, at 25.4 rpm (max speed) and 1008 hp the engine has (63025*1008)/25.4 ft.lbs of torque. Or if you plug that into a calculator. 2501149.606 lbs.ft. AKA *2.5 million* ft.lbs, or *3.4 million* Nm of torque!
Where did 63025 come from? The constant is 5252. You're out by a factor of more than ten. The actual sum should be (for ft-lb) (1008*5252)/25.4 = 208,426 ft-lb
Btw this is the same size engine that powered the titanic, as a matter of fact the engines of the titanic were possibly larger than this. Also, quick fun fact, the engines are still standing on the seafloor over 110 years later, meaning the bedplates (the piece that holds the engines up) of titanic are still operating the way they were intended after a violent sinking and 100+ years of deterioration
I've heard the ones on Titanic were bigger. We also still have Britannic's engines around too which are the same size. Both are underwater. It would be incredible to see those engines recovered from the wreck but thats dang near impossible just due to their weight and size.
@@Crazyguy_123MC i know i am one month late but it could be possible to raise Britannic's engines as its closer to the surface then titanic but they might have already become coral like most of Britannic and you would have to get permission from all the governments and other people
They still make them that big. Google Wartsila-Sulzer, the biggest diesel engines in the world, 3 stories high. They're what they use in Container Ships and Tankers.
@@brucerogermorgan2388 I'm sure they do. The ships are getting bigger, so the engines must get bigger, too. I'm sure that as technology progresses, we'll be able to extract more power out of a smaller engine, but with ships that big, we're still gonna need massive engines.
It's the largest *still running* steam engine in the world. But it's completely dwarfed by the pumping station of Cincinnati, where the four engines weights 1400 tons each, and are 11 stories high (or low, being installed in a pit). A full sized railcar can enter the engine house to deliver spare parts...
I cannot picture ANY students of ANY schools, putting out workers of the caliber needed to invent and build something as beautiful as this, and others similar. Damn shame, really.
I've been in the engine room of a Liberty ship with a triple expansion engine, much smaller of course, I think the low pressure piston is only 6 feet across. Amazing how silent it was, even at 60 rpm.
At first I thought I was looking at an art deco apartment building, with the arches and openings, it was as if 18th century milk maids where about to step through the doorway and start singing opera. Then I realised I was looking at a very big machine.

My...God. look at the size of that piston rod!!!! Its like 4 people standing on eachothers shoulders. That thing has gotta weigh many thousands of pounds alone! Hell...a regular engine, only like 2 feet square, is literally 500lbs and it isn't solid metal like that o.O

Big difference here this engine is a 3 cylinder. Titanics was 4 cylinder even though it was a triple expansion engine. They had two 3rd low pressure cylinders which fed the center steam turbine.
In Derbyshire, the Leawood pumping engine pumps 4 tons of water every stroke (7 strokes per minute), and it's big, but much smaller than the Kempton Park engine. (The Leawood engine is also the oldest non rotating engine in the world still working on it's original site. (It doesn't have a crankshaft.)). That's a rate of 840 tons of water per hour, or 20140 gallons in 24 hours.
@@zagatozele If you're interested it works out to about 2.5 million ft.lbs or 3.4 million Nm of torque! And that would be assuming peak power is at maximum RPM. At rest, or at a lower RPM it would be a lot higher.
Triple expansion steam engines were quite common. The SS Delphine, The Dodge family 257' steam powered yacht has 2 quadruple expansion engines.

Partly, a lot of skilled blueing & scraping by hand, involving hours of work to get all the bearings to fit, and much skilled work to prepare the foundations and seat the engine frame accurately on its base, and to fit all the other components together into one whole machine.

Interesting thing about steam engines: They develop maximum torque at zero revs, so there's not much point revving them high.
This is why steam powered vehicles don't need a clutch to disengage the drive when the vehicle stops, unlike an internal combustion engine.
