Hi Stephen, I never took any photo's when I did that set but here's what I did. I bent the channel in the folder to the size I wanted and simply bent it around the same shaped form of the original radius. In this case I folded the channel with a 5mm inside measurement. the material you see is 5mm thick and I just put it in the vice and just hammered id around part way. it will flare out but if you take it out of the vice with the form a couple of times and hammer down to shrink it then it will form the right radius. There was no rocket science in the way I do this and that was about one minute to form that bend. I had a form the same dimensions as the glass but I just can't find it. I hope this helps.
Colin.
