Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

   I now have a boiler that can keep up a steady 60+ PSI, and maybe the use of steady expanding steam as opposed to merely compressed air might help, although I can't see that if it took 160 PSI to run it previously. But the previous owner never tried anything else. I need to check to see if I have the right combo of threaded connections to try.
