Episode overview
Molten iron is poured into moulds, cleaned and finished before the heavy castings are assembled into wood-burning stoves. Lightweight structural components are joined into ultralight aircraft; tracked chassis, hydraulic systems and grooming equipment are combined into machines that maintain snow-covered trails; and cured rubber tubes are sliced into individual rubber bands.
