Hi, Sorry to learn a disability will prevent you from visiting a club. The Gauge 1 “Project” locomotive, although nominally intended for beginners, is not a particularly simple construction job if you will be working by yourself with no mentor at hand. In addition to making and fitting the numerous chassis components, there will be the boiler to construct as well as a substantial amount of platework.
If you are looking for a very first model engineering project, consider beginning with a single-cylinder Stuart Turner stationary engine, such as their 10V or 10H. There are two construction booklets available describing construction of the 10V. “Building a Steam Engine From Castings” by Edgar T. Westbury is the older and smaller of the two. The other, more informative one is “Building A Vertical Steam Engine from Castings” (64 pp.) by Andrew Smith, former employee of S.T. Smith’s book goes into greater detail with very clear drawings of each part, numerous clear photographs of nearly every machining operation, and thorough descriptions in text. If MyHobbyStore does not carry Smith’s book, try Camden Miniature Steam Services, another major book dealer. Check with Stuart Turner, too.
The cost of S.T. castings is not trivial, however, and it could be expensive to replace a casting inadvertently spoiled during machining – not an unlikely event! Therefore, another approach (below), is worthy of consideration.
On an very elementary entry level, there are two books to consider by Tubal Cain. Book 1 describes two types of boiler/engine combinations and a simple model steam crane. The SMEE uses one of the engines from Book 1 in their training classes. Book 2 describes somewhat more involved projects, going rather beyond the toy characteristics of the machines in Vol. 1. Both of these books are of the hand-holding type, the next best thing to having an instructor at your side. They include clear detail drawings of every part and patient instructions on how to make it. Some of the engines employ castings for which an English supplier is listed. The castings are very simple, so if one inadvertently spoiled, it could be replaced at minimal cost compared to some of the castings used for the Project locomotive or S.T. engines, or it could even be reproduced from solid material. All the boilers are meths fired. The titles of the books are “Simple Model Steam Engines, Book. 1 and Book.2” They were published by Nexus, a predecessor to MyHobbyStore, where you should currently be able to obtain a copy of each.
Since you are just beginning, consider an elementary project for your first attempt. The job will not be so long that you will become frustrated, and it’s very likely that you could complete both a simple project and another more complex one in the same time interval as if you began with the complex project!
I hope these suggestions will guide you in deciding where to begin. Regardless of what you do, continue to read M.E. and/or MEW to get new insights in this greath hobby. And remember, the forums here have great potential for assistance should you encounter any problems during your construction foray. Good luck!
