Physical Model of Stirling Engine Generator Small Engine External Combustion Engine steam Engine

Very good machined product

suggest using alcohol wick to make it work. Candles and things don't produce enough heat. Suggest make it work outside - don't want a fire inside the home. Great display item either way.

Appena comprato funzionava bene ma dopo la prima scaldata, alla seconda accensione non funziona più

I have been shopping around for over two years to buy a Sterling Engine, but never pulled the trigger until now. Come On... this model sells for almost $100 and I picked it up for $39. It came in a Foam Box, and bubble wrapped, fully assembled, bright and shiny polished and the only assembly was putting the LED light on the generator. I had a 50/50 chance of connecting the LED with the right polarity... worked first time and to my surprise, the LED changes colors as it flashes. But here is some past experience things to know about the glass elements of this model that get very hot... you already know to never touch a Halogen bulb with your fingers as it will crack, so don't touch any of these glass parts on this model, don't take any chances. I used some machine oil for my 3D printer to lube all the beam and piston linkages. I use 91% rubbing alcohol for the burner, they suggested 95%, 100% Vodka would work too, but after the initial flywheel pump that you do to get it started, pay attention to the sound of the piston and beam, and when suddenly it sounds like it just doubled in speed, .... important... blow out the flame and just watch it continue to run for a lot longer than you would ever expect. After playing around with this for several days, I'm going to donate it to a school science teacher. This was a cool Amazon purchase. 5 STARS

Ein optisch und technisch wirklich schönes Modell (mein 10. mittlerweile). Wird gut verpackt und komplett montiert geliefert (Lieferzeit allerdings fast 1 Monat). Einiges an Zubehör/Ersatz dabei. Nur ein wenig Spiritus in den Brenner, 1 Min. vorheizen und Rad in Schwung setzten. Habe ein kleines Voltmeter am Motor befestigt. Der Knirps erzeugt tatsächlich über 6 Volt. Keine nachträglichen Einstellung notwendig. Am besten vor dem Betrieb 1-2 Tropfen Feinmaschinenöl oder Graphitpaste auf die beweglichen Teile, wie Wellen und Gelenke geben (NICHT in/auf die Zylinder). Für Sammler dieser Maschinen eine Bereicherung. Verarbeitung, Preis und Optik stimmen. Findet in meiner Sammlung einen festen Platz.
