I would like to have a 180 deg twist in a thin sheet of aluminium (the thickness is not very important to me), length ~1m and width ~10cm. I would also like to have the twist to be spread all over the length, so that the curvature is small.
Is this something easy to make? Do I have to design special tools
I am not to sure I understand
but I think you can do it with rollers
