Peter, Thanks for the info on hand firing those Fairlies. I always wondered how one could manage inside the cab with the fire doors on the sides of the boilers. Now I see, you have to stick parts of your anatomy outside the cab to load the grates. Now, why would some idiot of a bureaucrat come up with some sort of regulations concerning the diameter of the air piping? I mean, usually pipes (at least here in the USA) are tested to about 1,000 PSI (453 KG) per square inch. I doubt that anyone's compressor will reach that kind of pressure except maybe in an industrial setting.
