Setting aperture hack ?

Hi folks, I am currently working on making an old Canon Vid lens into a working lens for my Nikon 1. Focus and zoom work great as manual; but, aperture is electronic.

I have opened the lens and the spring Iris mechanism moves smoothly, easily opening the lens up to 1.4. Once released the click-less Iris slams shut tight.

The lens is meant to be f 1.4 to 2.1, thus should I count it as a maximum 3 stop range? Or could I set it to to a smaller Iris settings of  5.6, 8 or even 11.?

My idea is to drill small holes into the aluminum casing, then cut a thin slit across their tops and insert a tiny 'stick shift' to be placed into the holes as lighting requires.

Maybe 6 holes will be too many for such a small distance.

Any ideas out their?
