Excellent, as always, John. Thanks for posting!

An Old Boiler

Occasional Special No. 3. Part B


Hello Chums

I know, I know! I shamelessly 'plugged' this 'Occasional Special' as having interesting stuff about locomotive boilers and all I've shown you is a picturingham of the firebox end of a boiler with the cladding removed. Nothing new about that - every steam railway enthusiast and her pet poodle will have seen one of these, either in the metal or in an illustration in a book or magazine. You'll be saying, "Pull your socks up, laddie, and show us something new."

After taking the course photograph seen in Part A, I shimmied [wobbled on crutches, more like] to the other end of the boiler and took another coarse photograph. "Not yet another picturingham of a smokebox," I expect you are saying. Not quite:-





You see, the boiler has been partly dismantled and this gives us an opporchancity to examine parts normally only seen by a boilersmith.

We have already discussed how, since Robert Stephenson's time, a locomotive boiler has an inner and outer firebox and a series of tubes. The tubes are absent, but you can see the holes in the inner firebox into which they fit. That's the bigger holes. The smaller ones towards the bottom are for the stays that hold the inner firebox to the frontplate of the outer firebox. This has been removed.

You can see the water space between the sides of the inner and outer fireboxes - possibly narrower than you expected.

The thick piece of metal, with lots 'N' lots of holes, at the bottom is called the 'Foundation Ring'. Certainly, it's the foundation of a boiler, but it is a bit of a stretch to call it a ring. More a rectangle with rounded corners. The inner and outer fireboxes are rivetted together through the holes in the foundation ring.

There's more to see, of course, but, for that, we'll look at another coarse photogarph in Part C.

To be continued...


'N' Gauge is Such Fun!

Many thanks for looking and all best wishes.

Agreed. Transition period modelling at its best and loved the running speeds !

Super spiffing videos.

Pretty sure Arran's already done a Stolt tanktainer.

I will have one of everything proposed! No suggestions on the other gaps. Tex 20' would be good, or maybe TAL in brown with the red Transamerica Leasing building logo.

I think 20 footers provide the opportunity for oddball rarities. I'd buy a dozen of any of:

Containerships

Cronos Containers

Balearia Cargo

An Old Boiler

Occasional Special No. 3. Part A


Hello Chums

When I wrote the postingtons about boilers for the remarkably brief mini-series, I was aware that I was describing parts of a boiler without being able to provide an accompanying picturingham. A recent visit to the Lakeside & Haverthwaite Railway provided an opportunity to take some coarse photographs of a boiler from, I understand, a Hunslet 'Austerity' 0-6-0ST, which might be of interest.

Before we continue, my greetings and thanks to the wonderful people at Haverthwaite who seem to be intensely relaxed at a coarse modeller peering at the innards of their precious locomotives.





The picturingham shows the outer firebox and the part of the boiler which protrudes into the cab. Called a backplate, faceplate or backhead, according to whom one is speaking.

The firehole is obvious. As are the mounting pads for various fittings such as the gauge glasses. The profusion of dome-shaped thingamajigs are the stay heads.

At the side of the outer firebox you can see one of the flanges which hold the rear of the boiler in place on the frames whilst allowing it to slide back and forward, due to expansion and contraction as it heats up and cools down.

The front of the boiler is fixed firmly to the frames, which permits the fitting of the steam pipes to the inside cylinders and their exhaust to the blastpipe without worrying about movement.

Finally, even through the mirk of my coarse photography, the welded insert repair to the outer firebox can be seen. A corroded or cracked piece has been cut out and a new steel section welded in. Careful work and diligent testing is required for boiler repairs as we are looking at a pressure vessel - in other words, a potential bomb.

Quote from: Moonglum on Yesterday at 07:04:41 PMFab Martin @port perran ... a school chum introduced me to Santana, probably "Abraxas"  but it wasn't until I heard "Caravanserai" that I became hooked and had their albums up to "Marathon". MS's drum solo is on a small kit compared to what we have nowadays.

Here is a more recent example of drum solos...

Did you hear the John Bonham bit?

Tim

Do you mean the Moby Dick soundalike bit?

As for the drum solo itself - not up to the Michael Shrieve standard to my mind.
More playing to the crowd rather than mastery of his drumkit.

Tanktainer-Liquid Air?

Carried helium inside nitrogen insulation/ sacrificial coolant inside glass fibre insulation. US to Europe, including Felixstowe.

Only remember carrying one other tanktainer westbound to US, possibly Suttons heated type but it was over 40 years ago...

ISO containers are too late for my modelling, but I well remember the Hornby red Manchester Liner ones, and carried loads of them on Montreal service.

Martyn

Later thought- Stolt tanktainer? I think they are rail hauled in UK.
