Diamond embossed edging stones & platform paraphernalia!
I mentioned in a previous blog entry that I was trying to to make a representation of the diamond embossed edging stones that the GWR commonly used on their platforms. I tried scribing some using a fine tooth saw on plastic card, but they didn't look very convincing I'm afraid. I thought that something manufactured by cadcam might be the answer, but quite how that was achieved was something completely out of my skill set!
At the Bristol O gauge show back in January I met Chris Ward of CW railways who has a business designing and producing parts for railway modellers by using CAD and 3D printing them in resin. He said he would be willing to have a go at producing some 7mm scale edging stones if I could provide dimensions and photographs of the prototype.
Fortunately this type of edging stone was used in a variety of situations in Victorian times and I found some suitable prototypes on a harbour wall at Barry island! I took a number of photos that I hoped would be useful for the project.
I sent some photos along with the necessary dimensions to Chris who came up with the following CAD drawing.
From this drawing by a process that I still convinced must be some kind of witchcraft the edging stones were printed in resin! The edging stones come in a strip about 150mm long and can also be produced to any given radius.

I must admit I'm delighted with the results, they are certainly a huge improvement over my scribed efforts! To highlight the embossed detail incorporated in the stones I've flowed some dilute Humbrol enamel paint onto the surface.
Chris has also said that he would be willing to produce a similar tile but without the bull nose that I plan on using under the station building canopy. Chris has added these edging stones to his range of modelling parts, so if anyone is interested in using these on their layout get in touch with him through the website. http://www.cwrailways.com/0-gauge-7mm-scale.html
Once I get chance to install the edging stones on my platform I'll update the blog with pictures of them in situ.
I've also spent time building some etched brass platform barrows and seats from Southwark models range of parts http://www.roxeymouldings.co.uk/category/88/7mm-scale-/-0-gauge-southwark-bridge-models-accessories/
They are certainly fiddly to construct, but do in my opinion have a delicacy and fineness that would be hard to achieve using white metal castings.
I've booked next week as leave from work, so unless Mrs Wenlock has any plans for me I'm going to make a start on painting the layout's backscene.
Happy Easter to all!
Best wishes
Dave
