Now that you have a piece cut to length it is time to bend it. Bending rebar is all about leverage. Place the rebar on the ground. Using a long metal pipe with a large enough internal diameter, place the rebar into the pipe stopping about six inches from the point you'd like to start the bend. Place your foot 6 to 12 inches (15.2 to 30.5 cm) back from where you'd like to bend. Pressing firmly down with your foot, raise the bar off the ground until the bar bends to the angle you'd like. It is often necessary to bend a piece a little at a time if you are trying to get an exact bend
