Model Boilers and Boilermaking by Karl Noble Harris. It is more than 60 years since the late E. L. Pearce’s excellent little handbook ” Model Boilermaking ” first appeared; it went through many editions but has long been out of print. Naturally, in the interim, many developments have taken place. This book is in the nature of an attempt somewhat to expand the original book, and so far as possible to bring the subject up-to-date.

I have endeavoured to provide such information and statistical data, as will enable any intelligent model engineer to design a boiler to meet his own particular requirements, with a reasonable assurance that it will do the job for which it has been designed successfully and efficiently. Model boilers are, to a large extent, the Cinderellas of model engineering. I think that the principal reasons for this are twofold.
Firstly, there is a great paucity of information about them. Secondly, with the average model engineer, the engine usually comes first, and by the time this is finished and he gets around to making the boiler, he is, quite understandably, in a hurry to see results, and he decides that almost any old receptacle that will boil water and is reasonably steamtight will do.
