its 4 inches in dia


no I did not design it ( I am not good enough with the stress calculation and material knowledge to do so )  I can build them OK but the design i leave to others


It was built from a GLR design I just order the copper kit from them ,beat up the tube plates flanges got it good and hot and stuck it together

BTW the info on their site it at total variance to the drawings you get  they state its a 45 psi unit the plans call it a a 90 pound SWP unit , then the go on to tell you to test to 200 psi hydro  the last bit is wrong the max first test should be 180psi.

to sort it out I did correspond with the designer and ran the plans past out clubs boiler inspector who did the calcs and said test to 160 SWP at 80 and retest at 120 psi


the drawings do contain an unmakeable component the fire hole tube is not able to be made as drawn , and the safety valve is a dead weight one not a spring one


Please note with boilers ALWAYS consult with your clubs boiler inspector at the start , during and testing the boiler ,these are not things to mess with without the help of a boiler inspector

BTW that unit is gas fired using a Polly ceramic burner

Stuart,  I think this is the boiler I'm using - with a shortened firebox - in my model Best steam traction engine.  Any chance of some photos please?  Yours don't seem to be there any more.

Kind regards, John Fearnley.

As I do not have the boiler now ,it's a non runner
