How to make a cam plate for a mechanical iris?
I was wondering how you would make a cam plate for the iris, I have spoken to him and he has said that it is made of a brass sheet 6mm thick and he used an angle grinder. I was wondering if it is even possible to make one using handheld tools? I live on a small island where there ar'nt many hardware stores, let alone with the right tools, and i'm probably not even going to buy them anyway.
So any ideas on how to make a cam plate?
