The engineering on this little beam engine is superb! Must oil all movement points. The shorter the wick, the better. May take 10 minutes or more to boil water (like a bigger steam engine does) and start your run , but worth the wait. If it runs within 5 minutes of lighting, the flame is still to big. Filling 1/2 full with water was a 20 minute run time after up to a boil. Setting the engine on a tissue really quiets the operation. No need to remove piston to oil, just a tiny drop to the side of it, same for valve shaft. Engine upper plate showed up to 150F, but burner base can be handled fine. Clean enough to run on kitchen table. A little beauty and great value. Also, surprising power, enough to ........? Safety never did open. One of my favs.

Estética e funcionamento muito bons. / Ao abrir a caixa, parece uma coisa muito pequena. / Olhando melhor, parece uma obra de arte para exposição. / Colocando a funcionar, é mesmo uma verdadeira e muito boa máquina a vapor. / No primeiro ensaio operou 25 min com 10 cm3 de álcool etílico 96% gastando 28 cm3 de água desmineralizada previamente aquecida. / Basta uma chama muito pequena para não rodar com velocidade demasiada. /***/ Very good aesthetics and functioning. / When you open the box, it looks like a very small thing. / Looking at it better, it looks like a work of art for exhibition. / Putting it to work, it is a real and very good steam engine. / In the first trial, he operated for 25 min with 10 cm3 of 96% ethyl alcohol, using 28 cm3 of previously heated demineralized water. / A very small flame is enough to not rotate too fast.
