I have two GEM Cambrian 2-4-0 tanks to build, 1192 and her sisters, and can't seem to find a reference to wheel details, I think the drivers should be 4' 6" but no idea as to the leading wheels or the number of spokes. Russell seems to have passed these locos over his two volumes (maybe there's another covering the absorbed engines?) any how, does anyone know of a suitable source of wheel? Gibson does two 4' 6" drivers but I suspect neither are correct.

Re: Wheels for GEM 2-4-0
According to Mike Sarman's wheel specification booklet the only Cambrian railway 2-4-0T was built by Aston in 1866, classed as Small side tank. 3ft leading wheels with 9 spokes. 4' 6" Drivers 14 spoke. 20"cyl stroke. 20" wheel stroke and pin between spokes.
Hope that helps.

Thanks for that Andy, I understood they were built by Sharp Stewart, now, who does Mikes wheels now?

Re: Wheels for GEM 2-4-0
Indeed 3 attractive little engines - pity you've only got 2 kits as there were also three clearly different stages, single bent sheet "cab", box like cab with new safety valves and the Westernised version.
Wheels were 9 spoke (3' on GW rebuild) with 14 spoke drivers with the crankpin between the spokes.
Above details are from Russell's "A Pictorial Record of Great Western Absorbed Engines" where there are two diagrams and six photos.
There's probably more in the RCTS book but I don't have that to hand.
The HMRS has a drawing of these locos:

and a photo of Seaham

Re: Wheels for GEM 2-4-0
Steve,
As well as Jim Russell's GWR Absorbed Engines, you will find all the required information for building one of these engines in Mike Lloyd's book on the Tanat Valley Light Railway (Wild Swan 1900). There are plenty of photographs of 1192, 1196 and 1197 in various forms as well as a meticulously prepared set of scale drawings by Mike for the GWR period of ownership. After there grouping I think at least two of them spent some time in the West Country e.g. 1192 worked on the Culm Valley line in the late 1920s.

I believe that some Sharman wheels can be had from London Road Models, but only along with the locomotive kit that they are suitable for. Other than that I think you can consider them unobtainable now, apart from the second hand market.

I was afraid that might be the case, Gibson does a 4' 6" wheel with the correct number of spokes and pin between, admittedly LSWR in origin, but the crank throw is listed as 9 1/2" ... a big difference to the 20" listed in Andy's information. Might just have to grin and bear it!
Thanks for the useful info, a good excuse to get a copy of the Tanat Valley book!

not that much difference, only half an inch!
The 20" is the cylinder stroke from end to end, equates to 10" crank throw.
The 9.5" is the distance from wheel centre to crankpin centre, equates to 19" stroke.
