For what its worth I have a 7.25" loco which was designed in accordance with Mr harris's excellent book and it has just been retested under the Southern Fed Rules. It has a rudementary drawing and a set of imperial calculations.
the Southern Fed Boiler and Safety Officer may also offer advice...
Hello Chaps
I think I get the message! Flanged sheet ends it is
the idea was to rivet the ends in place onto a deep flange before brazing and with the holes for the three flue tubes cast in it would simplify the construction for a novice as there would be no machining to do at all.
But thanks...
Gentlemen
I am proposing to build a gauge 3 model of a small 1900 bagnal steam loco. The original is small - 12' long and 6' high - cute!
It will be steam powered and have and have a marine type boiler - the combustion chamber is a larger tube offset from the main barrel - and it seems to me...
It has been suggested that I build a small locomotive boiler (3" od) in Monel Metal - It seems to be useful stuff.
Does anyone have any experience or advice
