What dimensions ( cross section , length ), how many per load, how fixed together, what colour ?

Engineer's Bar, typically loaded on Bolster Es and Twin-Bolsters, was 4" square, and 30-32' long. The loads I remember from Duport to Great Bridge were loaded flat on the bolsters and chained down (this was before tensioning straps appeared), the bars being loaded two or three high over the width of the wagon. Colour was a bluey-grey if fresh from the mill, with some surface rust if they'd been drawn from the stockyard. The ends would be painted red/yellow/blue, depending on the batch- there wasn't enough space to paint a melt number on, as would have be done on larger sections.

The photo mentioned above is in a book called 'Street Jewellery' Published by Cavendish c. 1988 (ISBN 0-904568-21-0). It deals mostly with enameled signs that preceded the hoardings. Another detail I've just spotted is that there is a low hoarding about 5' high and a similar distance in front of a normal sized hoarding, the frames seem to be made up of any timber that was to hand with no two pieces being the same size, from 2" X 4" to 6" X 12".

From the Squires and Dalzell tanks it looks like a Braithwaite tank is what is required, they are synonymous with industrial style water tanks, and still in production! http://www.braithwaite.co.uk/

 

If I recall they are basically a bolt together design to make a tank to whatever requirement the customer had.

Could Braithwaites be approached for a copy of a suitable 1970's design / engineering spec ?

 

Quote from the Braithwaite website :

 

"Braithwaite has a distinct pedigree which dates back to 1884 under the name of Braithwaite and Kirk at Crown Bridge Works, West Bromwich."

Looking at the Squires tank, it appears to be about 50ft high in total with tank sides of 10 ft high (sides 2 x 10 ft square panels). So in 4mm scale about 80mm square x 200mm high, but shorten for BCB purposes?

At the time of construction of that tank it is possible (probable?) that the sides would have been Cast Iron for corrosion resistance, rather than the Galvanised  Steel of more modern types.

What about steel sheet ? How was that transported ?

 

What about I or T beams - what cross sections for those ?  (I've got bits'n'pieces of these left over - I might as well use them up).

 

Also, what is the width between the bolster uprights ?

Theres certainly a lot of images out there and a pleasant few hours have been spent Googling!

 

I don't want to go down the 'etched kit' route as I would like the build to be unique to the project.

 

The thoughts at the mo are either to go for something 'traditional' or perhaps something a 'little bit off the wall', ie something like a conical or even circular.

 

Having said that, I quite like the look of this one: http://www.braithwaite.co.uk/graphics/products/grp1_1.jpg

 

Which to me is slightly different in the way the panels are laid out.

 

The main thing is there's lot of scope to build a freelance prototype thingy putting a bit of individual character into it :)

Steel sheet would be loaded into in Plate or Boplate wagons, with pieces of timber as spacers to allow slings to be passed underneath. I don't recollect seeing any securing devices on the loads in transit, as the loads would be below the wagon sides. The BR 'Green Book' suggests that there should be packing at the ends of the load to stop it sliding.

I, T and U- sections would be transported on bogie bolsters, with bits of wood placed between layers to prevent metal-on-metal contact, with the risk of sliding. The loads would be chained, or later, strapped. The lengths would vary, but the sections would be in what were called 'preferred sizes', which would be held in stock at rolling mills and stockholders; deviating from these could be very expensive, as the mill rollers would need to be changed.

Bolster uprights (stanchions) were normally movable across the width of the wagon; one BR diagram showed all the potential positions and spacings, which Lima took at face value when doing the Bolster E.. Instead of two stanchions per bolster, there were a dozen or so, with no space for the load.

Another 'metals' traffic which hasn't been mentioned yet was Pig Iron for the many foundries in the area; this might be conveyed in the specialist wagons built for it, or in Plate wagons. It could be represented by bits of sprue offcuts- a search for 'Pensnett' might produce photos of it.
