Page "Hobby" Paragraph 29

Model engineering refers to building functioning machinery in metal, such as internal combustion motors and live steam models or locomotives.

This is a demanding hobby, requiring a multitude of large and expensive tools, e. g., lathes and mills.

This hobby originated in the United Kingdom in the late 19th century, later spread and flourished in the mid-20th century.

Due to the expense and space required, it is becoming more rare.
