Welcome to the Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines - Enjoy!
Here is quick try at slowing it down, note I made sure foot pads not catching any heat.https://youtube.com/shorts/xW0taX2rLiE?si=sUwGzollo0cvmJFg
Happened to be 70% alcohol I had handy. As to runtime I only ran a short test but was having no trouble holding rpm. With experimentation I am sure a pleasing rpm setup could be fashioned.
It seems ebay has it in for Jin. I don't understand it myself because I have seen far worse feedback records for years.There must be a small group of just a few very small but vocal people who complain loudly or something of that ilk.Here is the e-mail I received from Jin:Hi Gil,I am very sorry to write to you, because our second store has encountered problems!This shop has been in business for 17 years. But unfortunately, because we are limited by the EBAY platform. We were limited by the buyer's three medium comments and the bottom share (we could not resist the transportation damage, and we did the refund processing in time, but the buyer still gave us a bad comment!)Now only before September 15 to improve the rating can only increase the store trading volume through this time (8.16-9.16)! What I'm thinking right now is that we offer a mini Stirling engine J06-E to have on the forums for sale. The lowest price is $29. (We don't make money except for processing costs and transportation costs EBAY transaction fees) as long as we can reach 50-100 transactions, we hope to recover the store.I'd love to hear from you.Regards,JinIt looks like a very fair deal to me. We get a J06-E Stirling Cycle engine at cost in return for our good feedback.Here is the link to Jin's offering:https://www.ebay.com/itm/235706420085 I have ordered one already and will order another.Gil
