Has anyone seen or used a bender for steel edging? I want to find a way to make it follow the curves of the ground (up and down) I use 4"x3/16" steel. I'm wanting to figure out how to bend it on the "edge". The only real luck I have had is using a torch and heat shrinking the edge. I'm kicking around the idea of a bender that locks into the stake pocket on the trailer. Thanks in advance.
