How to make an iris diaphragm?
I've been scouring the internet, and I still can't fin anything to help me, so I'm hoping someone here will have the knowledge to give me some assistance.
I would like to build an iris diaphragm. Yes, those things inside cameras. But bigger.
But I can figure out the size thing on my own.
What I'm hoping is that someone will understand the mechanics of it.
I've included a basic picture of one. Google image search might reveal other examples.
Basically, I'll need to be able to slide the leaves with some sort of handle so that they form a larger hole and then can close up again.
Here is a link to the entirety of the useful information I could find.
I would be incredibly grateful! As would, I'm sure, several other people on the internet that are apparently also trying to figure out how to do this.
Hopefully thanks in advance!
