An original device that can bend a bar, strips and other metal objects can be made independently in garage conditions.
Two pieces of a channel of different sizes after completion are connected by a steel rod in the likeness of a hinge. It’s convenient to work with the tool by holding it in a yew, therefore a metal round is welded to one movable joint so that by fitting a pipe on it to increase the force on the bent object.
With the help of the resulting device, you can bend almost all the iron objects that fit into it.
