Britannia boiler expansion clips

[fordfocus54]

I have just completed a total rebuild of the frames and motion of 5" gauge Winson Britannia no.25(1999), and I'm now ready to refit the overhauled boiler however, on the original Winson setup the grossly overweight cab was the only thing holding the firebox down onto the ashpan! As the cab was one of the first items to be consigned to the scrap bin in favour of the much lighter and in scale Hewson cab I would like to know how to attach expansion clips to either side of the firebox. Does anyone have some nice photos or a Perrier drawing showing these fittings which I presume screw into the foundation ring. Are they similar to those fitted on my GWR pannier tank ie; two interlocking pieces of angle?

A reasonable question, although the cab screws the rear buffer beam effectively holding the thing down, but I wouldn't like to turn it upside-down! By the time the pipes and the running boards are on, that's adequate for upright usage, but probably no good for servicing if you need to rotate the locomotive.

Hi Frank, as Standardsteam says the pipe work, cab floor, running plates etc are adequate for holding everything in place, which is the course JJ has taken with his Britannia as described in his Britannia Builder's Blog. My boiler weights close to 30 kgs empty and sits firmly on the firebox frame I made to hold the rosebud grate I adopted.
