Model engineering is the hobby of constructing machines in miniature.
The 'classic' areas of interest are live steam models (typically steam locomotives,
stationary engines and traction engines), internal combustion engines, and clock
Other popular subjects are Stirling engines, workshop equipment, miniature machine
tools and ornamental turning. These constitute stable genres which are often reflected
in competition categories at model engineering exhibitions.
Model engineers typically produce models made in metal. These are machined from stock
metal and castings. Some of these are intended as utilitarian working models, others
as highly meticulous display models, or sometimes a combination of both.
The model engineer usually purchases commercially available drawings which are used
as reference to make the models. However some people produce their own drawings,
or even work without drawings.
The most elaborate models involve hand manufacture of thousands of parts, taking
thousands of hours to complete, usually over a number of years or even decades.
There are some complete pre-manufactured kits available, but these are limited in
the choice of subject matter and are usually expensive.
