      Having just completed my very first steam engine (see 20130512_194510[1].jpg

      and

      20130512_194523[2].jpg

      for shameless plug) I need to think about something to run it before I get started on a boiler? I have used an air line and was delighted when it sprang into life (with a helping flick of the finger) but have had a suggestion about using an airbrush compressor and hose (changing the inlet to suit)

      I have found this **LINK** and this **LINK** but am not sure if they would be suitable?

      Also not sure if they will be a bit noisy and it would be better to buy one with a reservoir?

      Thanks

      Chris

          They are noisy, have a read of this thread

            Ahh – thanks

            As I am a diver, I might make something up and use a compressed gas cylinder – but think I will be have to be careful with the pressure (normal cylinder is 232 bar or 3300 psi+) so I will have to stick a diving regulator on it but the intermediate pressure for that is around 12 bar which is 170+ psi…

            …or perhaps I should bite the bullet and cough up for a small compressor with tank and put up with the noise when I run it to recharge the tank, but they are not cheap as the thread mentions (at least for the quiet ones)

              You proberbly don't need more than about 30psi, and it should run on a lot less. I find with my S9 Stuart Turner that it's not the lack of pressure, but the lack of volume of air. My home built workshop compessor will barely keep up. I tried a 12V compressor, it might be OK on a small engine. Ian S C

                Hi Chris,

                Congratulations on finishing your first engine. It's quite satisfying when the first one runs. I finished a very similar one last year. Here it is running on a car foot pump.

                Another shameless plug wink

                  Or make a very simple boiler out of a piece of 1.5" diameter copper or brass tube with ends soldered in and sat over a methylated spirits burner. Fill it with boiling water from the kettle and it does not take long to raise enough steam for a small engine.
