I saw this on a UK model site. I liked it so I made one from an old bolt and nut. I have a nice bender I made but this one is easy to store and easy to use for those quick bends that pop up. Use a wrench to make the bend. In my case a 15/16”. I’m making mine for a 5/32” wire. With a spacer or two you can bend 1/16 and 3/32” wire. Mine is not as nice as in the video but if it works it is good. Video to follow if I can get the link.
