Making and using cylinder relief valves

[@lukebrennan5780]

This was very nice. Interesting, brief and very clear. Looking forward to more.

[@andrewpullen3166]

Nice work! I ran one of those lathes for a number of years.

[@legoboysk]

Nice Work Edward. Glad you’re doing well since you left Wales.

[@Martin_Adams184]

Fascinating. Such a good explanation of the design and of the manufacture.

[@maestromecanico597]

Absolutely beautiful. But you did floor me with the lathe-from-a-supermarket line. Question: Will a similar valve be fitted to Tornado?

[@thep2steamlocomotivecompan19]

In due course it would make sense to replace the LNER type valves on Tornado but not until they are life-expired.

Great video, well done Ed.

VERY EDUCATIONAL FROM A SAFETY STANDPOINT! LIQUID HYDRAULIC DAMAGE FAILURE CAN BE QUITE CATASTROPHIC!! I ONCE SAW A PHOTOGRAPH OF A PENNSYLVANIA STEAM LOCOMOTIVE THAT BLEW AN ENTIRE RIGHT FRONT CYLINDER HEAD OFF IN SERVICE!! WORSE YET, IN THE PICTURE WAS AN SWITCHMAN WHO WAS STRUCK DOWN BY THE FLYING CYLINDER HEAD!

Great work and video 👍. Niceeeeeee slow mo loving the chips.

[@wexfordwaster7423]

Well done! Please can we have more of these? Also it was about the right length. Many thanks and best wishes.

We will do our best! However, to achieve continuous progress we need continuous funding www.a1steam.com/p2donation#/

@@thep2steamlocomotivecompan19 . You’ll get find you’ll get more funding with more exposure. I’ve commented to this effect a few times - one way to get more exposure is to put more effort into your UTube channel. You’ve a very nice website and facebook pages, so I can’t understand why your utube channel has been left neglected. Just follow what Simon at the Steam Workshop is doing with the Fowler NG loco, the two lads at Talyllyn are doing, ditto Festiniog. It might feel painful at the start but practice makes perfect (just compare the early Festiniog or Talyllyn videos with current ones …). There’s 100s of pretty boring videos of locos running all over the place on utube, but the interesting ones are where stuff gets explained.

@@thep2steamlocomotivecompan19 As you well know, I don't have one. But I don't see why this should prevent me - or anyone else - making what are intended to be constructive suggestions to the promotion of what is an admirable project. (While on the subject of promotion, I see that the individual who appears responsible for a very good documentary on Tornado for the BBC has also posted a copy on U-Tube. So what about thinking to link to it?) My concern at the moment is that all you are doing is - to use a phrase - preaching to the converted. Which doesn't get "new" money in.

So by around 2035 we will have Tornado the peppercorn A1 Prince of wales the Gresley P2 Highlander the Gresley V4

Nice video

It is indeed Britain's most powerful *express passenger* design and in today's world the most powerful overall but I think there where stronger freight engines like the U1 Garatt but I'm not sure If it exists so the P2 is the strongest currently.

[@thep2steamlocomotivecompan19]

No. 2007 will be the most powerful express passenger locomotive in the UK when it is completed.

[@DeCasoU1]

Do not confuse tractive effort with power. It is a force and as such is of little use when trying to assess how powerful a locomotive might be. This has caused people to believe that a diesel electric locomotive with a tractive effort of say 52,000 pounds (should be pounds force) is more powerful than a Pacific locomotive with a nominal tractive effort figure of around 36,000 pounds. Well the Pacific can produce in excess of 3,000 cylinder horsepower and the diesel engine fitted to the diesel electric produces 2,000 horsepower. You can also have two steam locomotives with similar tractive effort figures but one will produce twice the horsepower of the other. It all gets rather complicated.
