After much testing and many failures , I finally found a method to bend the tint tubes without collapsing or kinking . Here is a pic of the first of my 2012 arches. Still need to trim to size, clean the tubes up, glue the joins and treat with plastic protector. But I am so excited I had to share. [attachimg=1] Picture of the form to show no kinks etc [attachimg=2] Picture of the lap joint. I didnt achieve this with every piece but I know how to consistently do it now. [attachimg=3] Picture with a 1.5 metre piece of tube to show height. [attachimg=4] Just need to go get some more tube now so I can complete another 2 of these.
