How to Bend Metal Rod to Make a Perch
Bend it around something like steel pipe ( a mandrel).Clamp one end of the rod and the pipe in a vice and pull or push the rod around ; you can use a hammer  It does require a sturdy vice. After the first bend rotate the pipe and rod into the vice jaw to make more bends such as 180 or 360 degrees. Once you practice it is easy; i have made about 25 copper "S" hooks with 270 degree bends on each end; using about 3/16 ' wire. OR, the tools should work well.
