Here are some of the better known books on boiler building. During the computer upgrade the reviews have been misplaced. Volume 1 and 2 paperback and hard cover There are a number of others who's scan has also gone missing. |

I do not mean to come across as being arrogant or bossy but I feel it could be pertinant to beginners such as myself and other guys who wish to start in the steam world. Again, many kind regards, Ron. --- End quote --- If all the conditions are met it might be possible. But the commercial ones are designed with abuse to a point in mind. Small fuel/fire box larger water/steam space then the full can convert etc. A home made one, can also have a failure if all the conditions are met. Again they don't go like in the TV or movies like with the car explosions, a car parked across the street was rear ended by a drunk, We slept through it and the lazy/slow fire. What woke me up was the 200 people on my front lawn making noise! :doh: |

Well thank you all, I have certainly learned a lot, and probably so have lots of others. Your generosity in giving your knowledge and taking the time and effort to write and post it, is sincerely appreciated. :bow: :bow: :bow: Dennis thanks for your offer – accepted with thanks. :) :) :) Ron(Ronkh) are you happy? :beer: DaveH |

Ron, If I sort out your question correctly, it concerns the possibility of a separation of the boiler from the chassis of a model engine in the case of say, a failed crown sheet. Please correct me if I've gone down the wrong track. Thew answer is, always "possible", but hightly, greatly, unlikely. I have only known of one separation of parts upon the occurrence of a model boiler failure. Some years ago in the UK, the lower edge of a firebox wrapper seperated from the mud ring in a 5" gauge (1"scale) model locomotive while standing in steam. The resultant release blew the nearest adjacent drive wheel off the end of its axle and of course sent ballast and dirt flying. There was no serious injury reported but observers and examiners were perplexed at how a release of such relatively small scale could have the force to dislodge a drive wheel, especially when the spoked drive wheel would allow an ample pressure escape route. So far as a boiler leaving its frame and becoming airborne, no such event has ever been reported in an engineered model although over the decades many crown sheets (or their stays) have failed without catastrophic results. I specify "engineered" models apart from soldered brass tabletop toys which can blow at any time for a variety of reasons. The only explanation I can offer as to why no separations have occurred is that model locomotive boilers, even those which strictly adhere to scale detailing, tend to have more relative strength of connection than full size locomotives at the firebox end, while at the same time would have many times less propulsive force acting in the event of a crown failure. Not very scientific, but that's the opinion I have. |
