How to use an english wheel

It is, essentially, a rectangular frame bolted to a large stand.
The frame is shaped in the form of a closed letter' c'.
At one end of the frame are two wheels that are used to form the sheet metal. The top wheel is called the rolling wheel, while the bottom wheel is known as the anvil wheel.
