I would think if you had an old liner you could use it as a template. Aren't the paperboard ones basically all one piece and then stapled at the top? I have been holding on to my old ratty liner with hopes of making a metal one. Can you just pop the staples, unfold it onto a piece of sheet metal, mark your lines and start bending? That sounds way too easy but maybe that is it.
