Hi all just started back on my model for the winter period…………….. Now that I have most of it built I really need to take a serious look at getting a boiler design sorted I know all the sizes and wp I would like but designing it is completely a miss for me…….

BBassicly needs to be 20 inches long end to end

5 inches diameter

Working pressure of around 100 psi

Ideally gas fired

thinking twin flues with 2 burners and multi cross tubes

Basiccly that's pprett much what I require does any on on here think that would be possible to design

Hi Jason yh it is for the pyrte but the design has changed greatly and is now a lot bigger and in a wagon style model apose to a traction engine…….. How do I work out how much steam I need to produce?

I don't mind designing my own boiler if someone could lead me in the right directions for the calculations used to work out tube thickness etc?

I already have a good idea of the design wanted/needed thru looking and researching on google and wikki

Joining a club for me at the moment is no option to me due to not driving so will have to be designed in house so to speak although I will get the design approved by a boiler inspector etc

I just need the basic info to set me on my way
