I found that making a flange on a sheet of 2mm steel was quite difficult, so I decided to make a simple bending tool to help with the many repair sections I will need.
This is a copy of some designs that I have seen for sale, but made a bit stronger. The maximum width it can bend is about 300 mm. Any more would take a lot of force to operate.
Here is a test piece I bent in 2mm sheet. This should make the repairs a bit easier.
