One of the regular series of Wednesday night talks was on how to build a ‘Cracker’, a small geared 16mm steam locomotive.
It’s a very simple and easily-made machine which lends itself to a variety of body types, of which we saw several during the evening.
The website of the Association of 16mm Narrow Gauge Modellers has a description of the build process. There is also a link to a site where photos like the one below are shown, and from which drawings can be downloaded.
A similar type of locomotive is the Cricket, which also has the option of different body styles.
