Frazer, wow thank you :bow: great information in those two threads! It's going to take me all night to read and absorb. I've had ET Westbury's flash steam book and Benson and Rayman's experimental flash steam book for almost ten years -- they are well worn! I have also collected Model Engineers for many years and have paid close attention to Dr Chaddock's and Jay Bamford's work and Bob Kirtley's among others. R.F. Yates also collected a lot of monotube information in his book "Model Making." And even Henry Greenlee had a go at it with a flash domestic power plant. And then of course HH Groves, and his steam aircraft, who seems to have hit many advanced concepts all at once in his engines and very early on. Kind of like Parsons did in turbines. It's like these guys put 6 different major innovations in any particular step they make, and they just work out of the box. Anyway the above two threads are gold. Thank you again! :beer: |

Another web site I have bookmarked from a few years ago :- http://www.flysteam.co.uk/index.htm Might still be of use, he mentions the same names as you did. I want to make a small version (eventually), to run my models. Ian |

I don't know exactly what the boiler is for is it for a model or for a small launch? The use of PICs has had a great effect on boiler control I keep thinking of getting back into it but would consider some kind of feed back loop.Don't know what you think ? I seem to remember a couple of American designs in The Modern Steam Launch magazine I think the editor was Bill Fitt or Durham Also I think Lunevalley in the UK made a monotube boiler there maybe some info on the Steam Boat Association UK site http://www.steamboatassociation.org.uk/Default.aspx?pageId=1242242 Bobs drawings for Pisces 2 are available from My Hobby Store cheers |

A generator, Frazer, the specs are in the first post. I think electronic control using PICs is fine and interesting, very attractive and I really look forward to seeing more. But for me the need for a number of sensors and actuators and a microprocessor is a different direction than the one I want to head in. Control by wire is I think very applicable to a system with negative stability, where highest heat exchange and high temperature performance is the goal. I would love to see your work if you pick back up on that direction. That would be cool! I'm taking the opposite tack which is dumbing down the system and reducing the heat exchange efficiency to try to get more control stability. Most of what I am thinking about has no application to racing or automotive steam power. And so it is kind of interesting in its own right. As far as I know, the only surviving common practical domestic use for steam power are the pressure cooker and espresso maker. Both of those use simple mechanical control rather than electronic control of the steam itself -- and both are robust systems. I'm a sentimentalist. I still don't have DRO's on my tools, though I'm sure I will some day. Just not ready for it yet -- having fun acting like I'm back in the last century still! |
