    I ordered a copy and received it very quickly. It is very well written and easy to understand a good buy.

    Hi,

    I'm just starting this myself and bought Harris and Parts 2&3 of the AMSC codes. Part 2 contains a lot of stuff I found useful when trying to work in the fitting locations, such as the sizes for various bushes and the min web in the tube plate. Given that harris is pretty thin on detail in his final design chapters, this was invaluable.

    Dave.

    Just a quick question for the Aussies in the know....

    My planned build of a inglis type Scotch boiler 100mm diam. but under 1 litre capacity, would this fall under code 3 regulations, or code 1 ?



    Cheers, Neil

    Hi Neil,
    The codes are quite clear. In each of them, the "scope", or range of parameters allowable, is unambiguously stated.
    Code part 3 has a maximum allowable diameter of 76mm, so your proposed 100mm dia boiler is clearly within the scope of code part 1. The fact that it is only 1 litre is of no consequence.
    All parameters must be met simultaneously; barrel size, water volume, and pressure have stated limits. If any one of those limits is exceeded, then the next level applies. If any parameter of code part 1 is exceeded, then the boiler must be approved and inspected by commercial inspectors if insurance is required.
    Above all, please discuss the matter with your local club boiler inspector.
    Regards, Ian.
    (ex-AMBSC chairman) ;)

    Thanks Ian, much appreciated. I've been wondering about this for a while now.

    I have been given the name of a local club boiler man, so I will track him down and discuss the build further to get my head around the rules and regs before proceding too far.

    Cheers, Neil

    The last chapter in Martin Evens "Model Locomotive Biolers" is about testing boilers for efficiency which is the work of Jim Ewins. The chapter describes the test set up and results obtained from the testing.

    Now here is the good bit. I found a website that takes Jim Ewins research and placed it in excel so initial boiler design can be checked and compared to existing designs.

    A further page on this subject by Jim Ewins can be found here:

    Nice find Dan. That's handy info.

    I finally ordered a Part III manual on sub-miniature boilers ans the steel boiler manual.

    Hi Gerald,
    It took me a bit to track down John Baguley's new website. The information about locomotive design using Jim Ewins system is here:

    Now that this is a sticky of some books;
    Books
    ________________________________________
    Here is a short list of Books.
    (Maybe not so short ;<)

    K.N Harris's book Model Boilers and Boilermaking.
    (This one is almost considered the Bible among Boiler Makers)
    Found online PDF copy:
    http://www.fastonline.org/CD3WD_40/JF/424/19-422.pdf

    "Model Stationary and Marine Steam Engines" by K.N.Harris
    Found online PDF copy:
    http://www.fastonline.org/CD3WD_40/JF/424/19-423.pdf

    The next two have simple pot boilers in them;
    Building Simple Model Steam Engines
    Books 1 & 2
    by Tubal Cain

    Making Simple Model Steam Engines
    Model Marine Steam
    by Stan Bray

    Another Article/book to add,
    Safety of Copper Boilers by Kozo Hiraoka this nine page article was first in Live Steam & O.R. (Vol. 40 No. 6 Nov-Dec 2006) and is included in Building the New Shay.

    For those who want to really move along.
    "Experimental Flash Steam" by J.H.Benson and A.A.Rayman.

    This link applies more to full size equipment than models, but does cover steam basics;
    http://www.pipingnews.com/steam2.htm

    Not really a book but usefull,I found this years back
    The Truth about Steam Oil
    by Harry Wade
