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

 So the valves and Tee came in the mail today, so I went ahead and gave it a test run. It works great! the squeaker is pretty slow to refill, but that is okay, as I don't plant to use all but the last 25% of the down stroke, so it will have a good bit of time to rebound. I don't plan to put any kind of air ram in it, so the output will be pulsed. On the other hand I just realized I will be able to use this to keep pumping air into my fish tank if/when my power goes out.... I don't think I have ever had a practical use for any of my engines, so that is pretty neat lol. The second version of the pump plate is on the printer, just need to wait 2 hours...
