Yikes. This is more complicated than I thought. Thank you.
How do you know which blade to put on first, and how do you know whether they go on anti-clockwise or clockwise ?
The most common failure is when someone forces the aperture ring and breaks the locating pins off of the blades.
It's really not all that complicated... Once reset aperture blades in a shutter similar to yours. At the time instructions were impossible to find. First evening was tired so had a cup of coffee - bad idea. Finally fixed the blades. Memories are that it took a lot, I mean a lot of patience, but it wasn't all that complicated in retrospect.
