Thanks Chuck. :beer: I just went through Phil's build article again, and you're right! I don't know where I got the idea from it had to be soldered :doh: - and that was the trickiest bit of the build for me - that was a bugger to silver braze ::) Setting the valve flat on the face would be a LOT easier if its not soldered - it would basically just be a simple job of adjusting the plate pressure - as long as the curve on the spring plate closely matches the slit on the valve plate and it fits fairly square in the slot - no need to faff around bending the spring plate to keep the valve flat to the face like I had to do! :lol: :lol: :lol: And I even wondered about what kind of "solder" to use for this part :lol: :lol: :lol: - better go and edit the posts! I hope to see your one running soon :thumbup: ; making the engine base really took the most time and you're past that already. Phil's instructions are excellent; the only bit I had a problem with was - and I quote: "Finally, the last item in the valve push rod assembly to make (Photo 44) is the flat steel valve spring - no problem!" :doh: - That's all he mentioned about it and caused me the most grief! Kind regards, Arnold |

All's well that ends well! I haven't worked on mine for a while. I've been bouncing around between projects. Been doing some airgun work, building a new telescope, making some changes to my plumbing parts engine, and my opposed 4 cylinder air engine, which is now done. Chuck |

Hi Arnold, Iīm a bit late with my congrats, due to circumstances out of my control (a lightning bolt hit the house). An excellent build, and and excellent runner. Iīll just finish another Stirling, and then Iīll try my hands on a(nother) flame licker too. Your build will be closely watched over and over again, although Iīll probably make it somewhat different (donīt have the Duclos book). I very much like a build thread that goes into detail, why and how, as all of yours (and many othersī, Bogs gets a cookie/M&M...) do. Thereīs nothing like following behind a masterīs shoulder, when trying to learn how things work. Please, keep up the good work. :nrocks: :wave: |

Chuck, I know the feeling of bouncing around... I've found if I don't settle on a single project and get it done, I never get anything done. Have a lot of stuff on the back-burner myself, and I'm going to start attacking them one-by-one... - though another more pressing project came up that I'll start and finish first. Thanks very much Olli; much appreciated :beer: I'm by no means a master of any sort; in fact I'm pretty much a raw beginner, so don't take what I do or show as the best way to do things. In fact, I'm pretty much in awe of your work on Stirlings; that's something I'd really like to get my teeth into, so I'm learning from you as well. I've found a supplier of laboratory equipment locally, and can finally get my hands on some test tubes, so it won't be too long now before I try one :-) :beer:, Arnold |

Hi Arnold, having watched your build from start to finish, I wanted to say first off, every detail you showed, everything you spoke about was taken in and well appreciated, much of it "old hat", but of good value even to one with experience. In my own never too humble opinion, there was no excess, and those of a different opinion could skip over what was such in their minds. I learn as much from people doing things for the first time, and starting from a different point of view, as I do generally, from the experts who show their mettle here, as we all bring different backgrounds to the forum. Because of your build, I took a piece of salvage cast iron to turn a cylinder, and found it was too poor quality and porous to be used, but that induced me to use the other generator brush, after measuring my bore, and finding two thousandths clearance, and turning a new piston out of it, and taking great care to ease up to size, something I've got to learn patience on, as I'm accustomed to much larger parts and less need for the absolutes of accuracy, but now my engine will run until it is too hot, and will start again as soon as it is cool, where by leaving it alone for a while, or using my hands to cool it quickly, but I still need to fit a graphite valve as the bronze one is still scoring the side of the cylinder. Your first choice of cast iron for the cylinder never entered my mind, until I saw you take that turn, and that was a lesson for me, as I knew aluminum was a poor choice, yet used it anyway. I am about to re-embark on the radial engine, now that I have most of the cleanup after the flood done, and the first inspection from the insurance company behind me, and I've got my cylinders back from honing, leaving me no excuses. Your build was very well documented, illustrated, and your immediate success was inspirational for all those who are beginners, you showed there is no good reason a beginner can't do an engine right the first time, it's just a matter of taking care, and taking the time to do it right. All in all, I thoroughly enjoyed it, and got some inspiration of my own from it, even if it meant some of the other dozen or so projects got back burner for a bit. :beer: here's to engines, and those who build them :bugeye: mad jack |
