a claw hammer (or ball peen) and a piece of pipe (1 ft +). you can hold one end of the pipe in your hand and the other resting on something rigid (i.e. a fire hydrant). Rest what you want to bend out on the curve of the pipe with the location of where you want to bend and the direction you want the bend to occure on the highests spot on the pipe and along the direction of the pipe. HIT the object to be bent exactly on this spot with the face of the hammer. repeat until you are satisfied. Do not hit on either side of the pipe, hit on TOP of the pipe.
