Model engineering kits
A more demanding model engineering project, a propane fired 1:8 scale live steam train, here seen running on the Finnish Railway Museum’s miniature 7.25″ (184 mm) track.
These fall into two categories. Machined kits or unmachined kits. The unmachined kits often consist of drawings, castings, stock metal and all the necessary nuts, bolts and other fixings necessary to complete the model. They require machining facilities to complete. Typically this will include a lathe, drilling machine and possibly a milling machine. A good level of knowledge about machining is necessary to successfully complete these kits. Machined kits are a set of parts that are fully machined and only require finishing with hand tools, painting, etc. Workshop machinery is not required. The kit will typically contain all the parts necessary to complete the kit, including all fixings, pressure gauges and other steam fittings, etc. These kits require a lot less work than an unmachined kit, but are very expensive. Availability tends to be limited as productions runs are small due to the high price.
Building from scratch
Many builders do not use any pre-fabricated parts, ready-made castings, or even drawings. This is called “building from scratch”, and it adds another facet to the hobby.
Model engineers
Historically, some of the leading names in the hobby have been those who encourage others through their writings, notably Edgar T. Westbury, “LBSC” (Lillian “Curly” Lawrence), Martin Evans and “Tubal Cain” (Tom D. Walshaw), all writing for the British Model Engineer magazine. Kozo Hiraoka has authored several series of logging locomotive articles in the U.S. magazine Live Steam.
Many of the projects published by these authors contain detailed instructions and drawings for building steam and petrol engines, as well as locomotives in scales ranging from 1:24 to 1:8, capable of carrying passengers on a backyard railroad track.
The quality of work of some modern proponents of the hobby is astonishing, foremost among living model engineers are Cherry Hill, Gerald Wingrove and Barry Jordan.
Tools
Tools used for model engineering include the Lathe, the mill, the shaper, and the drill press. Until the introduction of cheap mini-lathes, lathes produced by Myford were fairly ubiquitous in model engineering.
