I have an old drawing MAP publication drawing M24.

There are two copper boilers described on it and i am interested in the smaller one, which i am currently making.

The drawing states what size of engine they are suited to in terms of cylinder bore, how ever there is no working pressure included.

Using the formula from 'The model steam locomotive' book by the same author i can get the working pressure to 80PSI.

Has anyone made boilers to these drawings and if so what working pressure did you calculate and decide on?
