PREFACE
Our purpose of embarking on the construction of a project of this type is to present a vivid and understandable fact that if given the necessary supports, that we the youth and Engineers in potentials can move this country forward as regards to technological endeavours.
Such as bird eye-view right from time immemorial has provide that a lot of time and money has been wasted without any reason. Money in the sense that the nation has been spending the hand earned foreign exchange on importation of bench sharing machine from China, India and some parts of the western nations.
Our roadside welding and fabrications technical who control half of the engineering productive capacity of this nation spend a lot of time cutting a plan street of metal with chisel without getting a uniform sharp cut, while some waste their time waiting for power supply to operate their cutting or sharing machine which is electrically powered.
The motive of this project is to reduce time, suffering and material wastage by introducing and representing a modern exposition of a manual operated bench sharing machine through which metal sheets material can easily shear out without much suffering.
Perhaps structural difference may exist between this machine compared to power shearing machine but its working principle is the same. Though the main frame of the machine is formed by welding and filling, other methods such as casting and forging can be use to produce the main frame and also its component parts.
