24 forum posts | I want to run a Stuart S50 on compressed air, but only want a small, quiet compressor, as it will be kept in the house. It will be run at very low speeds, & with no load. If the engine runs freely when turned by hand, will an aquarium pump give sufficient power, - there is a full Stuart Beam on youTube being operated by this method. If so, what power of compressor will I need to give 10-20 PSI, as aquarium pumps are rated in litres per hour ? Any help will be appreciated. Mike. |

526 forum posts 45 photos | Although more expensive than an aquarium pump, I believe you will get more satisfaction from an airbrush compressor. Certainly a more versatile appliance (unless you have an aquarium!) Lidl and Aldi have them for sale from time to time if you can wait. Otherwise have a look at eBay 131015709681. If you see this in time, 131425392878 looks like good value. Dave |

2032 forum posts 41 photos | Hi mike. Don't know the s50 But this might lead you to a ballpark figure. . Area of piston x stroke of piston...x 1( or 2 if double acting) x pressure ( in bar).. Will be the volume of air per stroke.. Multiply by rpm will give the volume per minute. .. Area in case you didn't know..diameter of bore D A= pi (D*D/4) If you measure D in mm and stroke in mm The volume per stroke will be cubic mm..to get that in litre..divide by 1 million.. Eg 20 mm bore 20 mm stroke double acting 30 rpm at one bar( 15 psi) 3.142*(20*20/4)mmsquare * 20mm *2 acting /1000, 000 *1 bar *30 rpm.. *60 minutes Or about 22 l/hr Edited By jason udall on 15/02/2015 22:52:46 |

![]() 25215 forum posts 3105 photos 1 articles | As the average aquarium is only two feet deep these pumps are not intended to run at any great head of pressure, you will find they run out of air as soon as any great head load is added and won't work at much over 5ft depth, koi pond pumps go deeper. Given that 3ft is approx 0.1 bar then 5-6ft is 0.2 bar or 3psi. As dave says a small airbrush compressor will be more use but watch the cheap ones as they can be very noisy. |

2011 forum posts | My wifes car came with a tin of glue and a tyre pump, these have been replaced by a proper spare wheel. Yesterday I was playing about with the pump and it seems this could be a useful w/shop tool. Runs of 12v DC ,up to about 50psi. A small air tank and a pressure switch makes a good little tool. |

How do you add a link to a previous thread ? .. Paul, It's a bit laborious: Find the old thread, select its URL, then add it as a link like any other. MichaelG. |

![]() 7468 forum posts 230 photos | I tried a portable 12v tire compressor on a Stuart Turner S9, 1.5 " bore x 1.5" stroke double acting, no go, the volume per minute not enough, maybe with a tank the motor would run. This is a some what bigger motor than the 10V, but these little compressors are noisy wee beasts. Ian S C |

![]() 1022 forum posts 127 photos | Find an old fridge and remove the compressor/motor and use that, not very environmentally friendly if it is still gassed up but they can be purchased on that well know auction site. Add a small receiver and it should be a low cost option. Bob |

![]() 7468 forum posts 230 photos | If you are careful with the mounting of the frig compressor, it should be quite quiet, use rubber isolating blocks, and don't let vibrating metal parts touch the frame. Ian S C |

2276 forum posts 801 photos | Hi Michael, Running small engines on air was also discussed in a thread called "Air compressers for steam engines" In which I said that I saw some small engines running on a steam cleaner. Very quiet and real steam. Paul. |

1 forum posts | I just got an airbrush compressor from there. It is a really nice option, as for me. Maybe, it will work for you |
