Hi Bob, all
Please don't hold your breath - we are probably 6 months away at least from being fully exhibition ready. We had some layout "misbehaviour" problems at the Convention that prevented the "pretty's" like layout skirting and and some other display items from going out onto the layout.

So we still have some more trouble to "shoot", but we were running the full operations at about 1/2 capacity.

Post convention, we are concentrating on building the final buildings for the mine. There is still also one other module that needs more vegetation (aka rainforest).

Dan Pickard got some photos of the layout being set up at the convention. See https://www.flickr.com/photos/146324467@N05/albums/72157690927955603/page2
New buildings include the Lamp House, Weigh Cabin, Workshop (cutaway to show interior). The Boiler on the V block is to be bricked in as part of the yet-to-be-built Powerhouse building.

Now back to "potholing" the layout build history - still only another 8 modules to go...

Hi Oz  :wave:



Good to see some more 'Corrimal' Postings !  :bg:

We need MORE coal !  :thumb:



I really like the last little series of photos from the previous << Page, on this corner of the layout.

What a great feature & could just as well be on a diorama or micro-layout.

A lot of modelling in a small space !  :shocked:
























I think the photos show, a good scenery 'strategy' is ... Building up using different layers.  L:

I think it is less daunting to do, when you have a good 'layers strategy' !  :P



Very  C :cool: :cool: L  final result.

Nice work Oz !  :mex:



:moose: :moose: :moose: :moose: :moose:



Si.

In one of my books (circa 1922) there is a plan for the brick work for the Cornish boiler you have for your power house.

If you like I will post the plans on.

Hi Ken and all,
Yes please, ONLY if it is not too much trouble.

The reason that the rivet bands on the boiler do not go beyond the top half of the boiler is that I am planning on bricking it in similar to the Lancashire boilers shown in the South Bulli colliery powerhouse photos at
https://www.illawarra-heritage-trail.com.au/electricity-in-the-illawarra-coal-met-industry/

Only the external brickwork around the boiler will be modelled. I also think I can get an "acceptable" vertical feed pump by filling in the fins on a Westinghouse airbrake compressor. I'm still trying to work out in my head how I will manage the flue and main steam line going offstage "into the crowd". I promise that there will be more on powerhouse planning when my build history potholing gets to the mine modules and "what went where" on them.

The powerhouse will be another cutaway building the following photo of the foamcore mock-up should give you an idea of where it fits.

with the boiler going in at the front left of the building.

and a closer look at the end of the trestle over the bunker

This track fed an end-dump tipple - another thing I have to fudge. L:

The skips were shoved into the end-dump tipple manually - another scenic cameo for the trestle. 
Along with Neddy and his wheeler hauling the empty skips away on the other leg of the trestle. (Photo by Dan Pickard)

Photo of the brick setting for a Cornish Boiler.

The flue gas flow is a bit confusing.
 
When it exits at the rear of the boiler,
it splits and makes a second pass along side the boiler.
Then it meets at the front and drops down,
to make a third pass under the boiler,
before exiting to the stack.

Spent 35 years as a Power Engineer,
so feel free to ask questions on piping, equipment, etc.

Both plants I worked had their starts in the early 1950s,
so there was a interesting array of equipment to be operated.
Some of which perhaps should have been in a museum!.

Thanks Ken,
That diagram helps a lot. I did see some "undressed" Cornish and Lancashire boilers when I was in the UK last year. Like this Cornish boiler at Blist's Hill village near Ironbridge


But I've yet to stand next to one of these in a "dressed" state with the brickwork around it. So I'll just have to build a model one for the Corrimal Colliery powerhouse.  :)

It is not to often you will come across a boiler complete with setting,
the brick work has usually broken down and left a pile of brick on the ground around the boiler.

In my collection I do have a few photos of boilers in various stages of decay,
with just about anything reuseable having found a new life in some other operation, or scraped.

Hi Ken,
I can understand the brickwork breaking down. Depending on its mineral make-up, one of the things I can remember from my metallurgy training was volume changes in refractory materials with temperature, both on the way up and when cooling off - with about a 10% volume change on the way down.

That's one of the reasons you can't stop things like blast furnaces and coke ovens batteries in the steel industry - the brickwork falls to bits when they cool off.

When I was much younger, I operated a Lime Kiln,
took 5 day's from pulling burner to allow access into the kiln.

With sour gas furnaces, it was a 3 day cool down for access.

Most interesting refractory failure was during the initial dry out period,
the furnace lining failed and caused over heating of the furnace shell.
Needed 1/2 of the vessel to be replaced.

Interesting time's, all behind me now.
