Ive built quite a few in copper for small engines, but now want to build a steel one big enough to easily power a Stuart 5a sized engine without running out of steam! It will also need to provide enough power to allow the 5a to pump water to the boiler. Ive read a few books but cant fathom what size it should be. Any suggestions? Boiler will have 1/2" copper tubes, pre heat coil etc. Coal fed, conventional design. I recon it will need to be quite large! (You cant compare a horizontal loco boiler, they are just too different).

Not an answer to your query I fear but a fellow seeker!
I have exactly the same problem although I would want to fit a ceramic gas burner rather than struggle with coal firing again.
Since moving to deepest southern Shropshire I haven't found any of the model engineering fraternity within a days march of home so I will have to use this forum for advice.

How big a boiler? Try going to **LINK**
Maccsteam.com has the formulas needed for you to work this out. 6” and 7” Copper tube is available, my big steam boiler is made from 1/2” steel pipe cant be moved without a crane weight is a big problem,

for a large engine too, I was tempted to build a boiler similar to this one, riveted and soft soldered only, it looks nice and strong, or should I stop to chicken out and go for a brased job ?

There is an excellent book titled Model Boilers & Boilermaking by K N Harris, it is a worthwhile book to search out.
full of ideas and technical information, it was published by Argus Books Ltd of Watford. in the 1980's
