Culture in Småland, Beijer spark plug engine driving a saw The forest has long been and still is one of Sweden's great natural resources. In order to utilize the trees, the logs must be processed when houses are not being built with solid logs. Processing that began with chipping, later sawing by hand that was mechanized by single-blade water-powered frame saws. Water is still used, but on a very small scale. As a complement were steam saws that could be placed in places other than by watercourses. When the internal combustion engine became more common at the beginning of the 20th century, crude oil engines, also called spark plug engines, were manufactured in many places, and the closest one in Kronoberg was Torps mill. The engine in the film was manufactured in Vimmerby, but was also manufactured in nearby Kristdala, and the advantage of these engines was that they could be built as "village saws" where there was a need and long transports were wanted. Today we might call it ecological thinking, and the spark plug/crude oil engine can also be run on “anything you can burn in a heated frying pan”, which means everything from mineral oil to locally grown rapeseed oil, melted lard and more. Perhaps something to think about now that politicians are thinking of phasing out fossil fuels. Rottner 2016 Björn Carlsson
