Dean Bogies
Can anyone point me to drawings of Dean coach bogies - 6' 4", 8' 6" and 10' ?

Just to save me ploughing through volumes and volumes when I reach home after work - there's nothing in the usual Russell volumes as sources?

Thank you for the thought, Paul, but regrettably, no. I cannot find any anywhere in my fairly extensive library.
I am after a diagram so that I can get some cosmetic sides printed. I am not sure of the length of springs for each wheelbase or any other variations there might be. I gather the general arrangement is similar for all but that there are some differences.

David,
I know of a possible source, and will make enquiries.

I am sending a drawing by PM which may help

Re: Dean Bogies
There are small scale reproductions in "A Pictorial Record of Great Western Coaches including the brown vehicles Part 1 (1838-1913)" by J. H. Russell; Oxford Publishing Company, 1972; SBN 90288803X. Most, but not all, of the dimensions are readable.
The 6'4" bogie is on page 89, the 8'6" on page 93 and the 10' on page 95.
There are good photos and descriptions as well. Also detailed drawings of brake cylinder and Mansell wheel and carriage framing although the latter is not likely to be of much practical use in 4mm modelling.
When it comes to modelling these a couple of questions come straight to mind.
1. what's the best way of modelling the scroll irons?
2. has anyone made a 4mm model suspended "properly"?
My own interest in these is not for coaches - some use of this type of bogie was made on locomotives and there are one or two of these on my list of things to model one day.

Re: Dean Bogies
There are drawings of the three standard gauge (NG) bogies in the NRM/OPC scheme. Copies of the drawings can be obtained from their Search Engine facility. If you can visit you can see the aperture cards and make sure that they are what you want.
Dean 10ft bogie: NRM/OPC 1615 dwg of Jun 1895)
NRM/OPC 8386 of 1898
Dean 8ft 6in bogie: NRM/OPC 13194 of 1893 - 6ft springs
NRM/OPC 13195 of 1893 - 4ft 6in springs.
NRM/OPC 13513 of 1895 for Lot 630 (E35)
Dean 6ft 4in bogie: NRM/OPC 8665 of 1892
NRM/OPC 13510 of 1891
The OPC list can be downloaded from the NRM web site <http://www.nrm.org.uk/researchandarchive/archiveandlibrarycollections/railwaycoworks>
Do check what I have written above against the list. The numbers quoted above are the OPC list numbers not the GWR drawing numbers and the 18xx numbers are the quoted date of the drawings..
Best of luck!

Andrew, I assume from your question that you're talking about the spring. Whilst it was a bit of a fiddle, I have managed to model the scoll by incorporating it with the top two leaves in a single strip of brass of appropriate width and thickness. The two ends butt together on the upper leaf where the joint is helpfully covered by the strap. Additional leaves are added as necessary. Should you need more details, please e-mail.
Derek.

Thank you for this, John. I am grateful you found these as I find the NRM lists totally bewildering. I have looked before but got hopelessly lost.
Thank you, too, to the other people who have contacted me. Your help is much appreciated.

Derek,
Apologies for the slow response, the last few days have been rather hectic.
The scroll iron is the forging(?) that is fixed to the solebar and to the cross beam under the bogie and is a rather complex shape. See the bit clipped from figure 92 in Russell's book.

Re: Dean Bogies
Andrew,
Oops! In that case, what are the circular bits at the end of leaf springs called? I was thinking about the scrolled ends of handrails on finely crafted balustrading, which they resemble. So I'm sure you can appreciate my error. As for an actual scrolled end...?

I regret I've no idea what the names of the bits of the spring hanger assembly are.
