Figure 1 :The improvised material: Stainless steel can conventionally used as food carrier and a drainage pipe of brass have been used to construct an irrigation can. The can is drained by a plastic rubber tube which is normally used as drainage tubes for petrol and water in many homes in Nigeria. A ‘dog chain’ has been improvised as light cable suspension chain. The basic equipments have been fabricated using materials obtained from the scrap iron market. The production costs are small fractions of the prices of the imported brands.
