Hi guys
I'm looking ahead here and thinking about a future test boiler for when I begin making the various backhead and injector fittings... I found drawings for a boiler designed by Tubal Cain that's rated for 80 PSI, ID M36... Do I actually need a test boiler that goes to the working pressure of 4472's boiler (100PSI) or would this 80 PSI do the job?
I want something that's simple/quick to build but also with the bells and whistles that I may need for the future.
Does anyone have experience of this particular design, any pros/cons about it and would it be good enough for what I need? Alternatively, can anyone recommend something that may be more suitable?
I guess another question would be, any idea on material costs involved in making said boiler?
Over to you guys, all opinions welcome.
Pete

For testing injectors, you'd want to know that the operating range went up to your boiler's rated pressure. No point having a boiler blowing off and dodgy injectors.

Thanks, Wilf, I suspected as much...guess I best keep looking for a design.
Cheers

You could do a lot worse than copy Roger's design

On a seperate note, does anyone have the Tubal Cain drawing for the M36 test boiler of 80PSI or something similar that they would be willing to share?

You could start with an old fire extinguisher, co2 type

Good idea Jem.. I may have something in the offer which is a steel vessel...I'm awaiting details later tonight... I'll, of course, report back here ...

Pete
