This arrived the other day. I believe it's a Poly Models 1/3 scale...... Very nicely machined and first off assembled/ unfinished. .....*(Edit, mid November...... Ignore that last sentence!).*..... Complete with broken foot, and slightly bent crank. Which I did know about. No problem! :thumbup: Guess it's been dropped....... :doh: Slipped a small piece of esbit under...... We have a runner! :clap: Do I fill the rusty hole with water, and keep it topped up? Some form of instructions/ ideas would be appreciated. There's next to no mention of these engines on HMEM! ::) |

Nice looking engine, Same as any hot air engine it's got a hot end and cold end. Looks like the top of the displacement cylinder does have a water jacket so yeah fill it with water. Looks like there's a drain on rear. I would apply light oil to all joints, a drop on the displacer rod and oil the piston too. Nick |

Well Still, that is a nice looking engine, a little tlc, and a couple of toes and half a foot, a spot of paint, and you've got a nice running display. Can't say's I've ever seen one of those before, but it is interesting looking in its intersecting linkages, you ought to post a video of it, so we can hear it, too. Very nice if I say so myself :bugeye: :thumbup: mad jack |

Nick, Jack, Thanks for your comments. I've been into the shed, with camera...... But! ::) With water, it's not as happy as was.......... Lurched to a standstill..... I had a closer look........ Water from shaft, and piston. ::) I didn't intend running it as is. It was bought to set up properly as an autumn project. I would like to see a pic of component pieces/ whats inside, if anyone can help. Before I start having to prise the Hylomar joints apart...... :scratch: David D |

Jack, Here's a vid of the real thing, at Stew's favourite Museum...... I saw this engine, and thought, hmmm, maybe, I could..... :scratch: Then a member of my other forum posted this, and I realised castings were available...... http://modelsteam.myfreeforum.org/about32786 Then, when this one showed up, on Ebay. I thought it would save on machining time. :lol: All within two weeks! :thumbup: David D |
