Amazing job, Rick!  The ability to make such a sensitive part is just awesome!

Thanks, i don't think I can make the ones for automatic iris. I will need a press for that
the shape has to be maintained which is very hard when doing it with a hammer.

i had to sacrifice. it is the MIOJ nikkor-Q, it's a very rare lens and very sexy like Kuroki Kaoru

Wow, good job!
What is a 10.5/4 MIOJ Nikkor-Q ??
I know of the Nikkor-T 10.5cm/4, but that lens has 9 aperture blades, not 8 like the one shown here

Fascinating work!

I totally agree. It is good to see that this important work is captured for new generations!

Rick, could you share an image of the finished lens with the aperture stopped down by one stop or so?
