Well, for bending it is necessary to use a plate)) and for bending it, it is necessary to kill a bolt (with a thread, if anything), two nuts (if anything, also with a thread), because the thread can be used for other really necessary purposes ... Yes, and you still need this miracle must be welded (and not screwed) to the workbench, we don’t need a workbench anymore, except to bend the metal

What's a craft? 5-year-olds really do this kind of shit.

and to think that this artifact was first in your mind friend and you took it out into the world creating it that is ingenuity I congratulate you on your iron bender it is always necessary

Great idea! Have you made a tool to bend loop or “P” type clamps? I’ve been struggling with a way to make them repeatedly

Instead of a pressure roller - a roller or just a tube on the shaft. It will be easier to bend. Good luck.
