A pulley is a device made of a wheel or shaft that may have a channel within two projections around its perimeter. A pulley is made of a single wheel and with a path for a cable or a rope at the wheels edge. They come in different forms and sizes used to lift objects of different weights. The huge pulleys are made in factories, whereas small pulleys can also be hand-made. One has to follow the following steps to make a pulley:
- The first step is to remove a wheel from somewhere. You can decide the wheel size depending upon the size of pulley you want to make.
- If you have removed a wheel from a cycle or a vehicle, remove the tire on it.
- Now take a long wire that can be protracted from one side of the wheel, round the path of the wheel outside and to the other end of the wheel. The wire should have 4 inch of extra wire on each ends. Make sure that the wheel spins.
