Every year, members of my other forum have a charity steam up, at Eastwood in Nottingham. Near to Junction 26 of the M1 motorway. Hence..... The J26 Steamup. On behalf of the Rainbows Children's Hospice. Last year, we made over £2,500. Presentation day....... At the end of the day, this orphan was left on my table. It will be recycled, then auctioned on forum......... I believe it has traveled all the way from Australia. Then had a little adventure here. Before finally coming to me......... Stripped......... Another poorly designed Seig engine. Unfortunately, there are a few things, not right. The aftermarket perspex base holds the burner in the wrong position. The displacer is too short, compared to the swept volume of the hot cap. The ratio between pistons is only 1.15. I'm thinking of enlarging the displacer volume, this time. As opposed to (usually) sleeving down the power cylinder. Hopefully, there will be steady progress. As and when, I can get comfortable workshop time........ David D |

David, this looks like it will be an interesting thread. I will be watching your progress with interest and hopefully learn a thing or 2 for the day when I get round to build my first hot air engine.......OZ. |

Thanks OZ! Hot air engines need that little bit of magic to be successful. :smart: But, the correct design, in the planning process is a good help! :thumbup: Two earlier adventures. Both with the same problem as this one.... http://madmodder.net/index.php?topic=7223.0 http://madmodder.net/index.php/topic,8821.0.html David D |

That will keep you busy. No magic needed just a big hammer You only need one qualification to build hot air engines :loco: Thanks for the cuppa |

If I could wield a "big hammer" the way you seem to do. I'd be a happy man! :headbang: That one qualification isn't lacking here. Or, is it just stubbornness? :loco: Cuppa? Any time Pal! :thumbup: David D |
