Are you sure you want to make an iris diaphragm? The thin metal leaves are easy or hard, depending on your method. I would etch them out of metal foil. However, there are pins at the end of the leaves and at one end the pins run in tiny slits. You will have fun making all those slits, though they can be made by filing and drilling. Wouldn't it be better to find a scrap shutter or lens with a diaphrgm and "borrow" it?
