ABSTRACT
Stop clocks are devices for indicating time duration for the occurrence of two events after a passage of time. They are usually powered by batteries and they measure time in unit of seconds. Most clocks stop working as a result of the inability of the main spring to make a complete revolution. Also problems that do arise in clocks and cause it to breakdown include worn gear teeth, pendulum friction, and sympathetic vibrations among others.
To effectively carry out repairs on stop clocks or other clocks, simple maintenance should be carried out. This includes clearing and oiling the parts of the clock mechanism. In the repair of the stop clocks the clearing and oiling procedure was carried out whereas in the others, simple forgoing of metal drips was done and fitted into the clock to ensure they start working.
The total cost of the material for repair of the stop clock is N2, 000 while the labour cost is N5, 000 to bring the cost of the project to a totalN7, 000 certain guideline and recommendation were made to ensure a lasting usage of the stop clocks. References were made from various textbooks and information was sourced from the Internet to help in the repair of the clocks and researches in this project report.
