The design and force analysis of a mechanical pedal powered hacksaw developed to modernized and less stressful operation for cutting of engineering materials. The machine was tested and found to be very efficient with an ideal mechanical advantage of 1.22, velocity ratio of 1.64m/s, a power output of 0.395kw and an efficiency of 74.4%, which makes it very adequate and capable for cutting. Furthermore, the rotational speed of the flywheel was fond to be 10.3 rad/s. It is very useful for cutting PVC materials (pipes) and can be used widely in lather and in furniture making industries. This work can also serve as an exercising machine for fitness while cutting; it uses the principle of a slider crank mechanism which converts the rotary motion of the flywheel to the reciprocating motion of the hacksaw during pedaling.
