This manual, which describes how to build a machine for rolling sheet metal into curves and cylinders, gives full dimensions and assembly instructions. This machine would be a very useful addition for any workshop producing items in sheet metal. It allows quick and easy production of curves and cylinders for articles such as stove pipes, buckets, water troughs, fuel tanks and agricultural equipment. It is also useful in vehicle building and repair work.
Designed specifically for construction from readily available steel sections, the machine could be built by most small metal workshops and blacksmiths.
The ability to make, locally, equipment for small farms and villages in rural areas, is increasingly being seen as very useful, both in the developing countries and in the more industrialized nations. Being built locally also means 'can be repaired locally', a very valid point when considering remote rural areas, transportation costs and local self-reliance.
The clear illustrations and step-by-step building instructions make this a very practical manual for any small workshop wishing to increase its capacity to fabricate in sheet metal.
The author (who also illustrated and laid out the pages for this manual), has a background in 'practical' engineering and appropriate technology workshops. His business, ApT Design and Development, based in Gloucestershire, England, designs and makes a wide variety of village-scale equipment for workshops in both developing and industrialized countries.
Rob Hitchings is interested in hearing from other designers/engineers who are building similar equipment around the world and hopes that a network of people may emerge who can share ideas and collaborate together to develop further designs.
