This engine was built by using some available parts according to my well-approved and reliable principles, including transparent cylinder. The base consists of flat aluminium parts being soldered together. This proves that aluminium can really be soldered (solder available at Hans Rexin), but it becomes relatively soft by heating indeed. By the way, this engine was sold at the auction at Ebay.
