I am sorry to tell you, it will not work.
The issue is; as you change focus distance, the posts will drop deep inside the barrel and so the aperture will disengage. This is why the post needs to be extended and the fingers need to be recessed as I have done it.
Why did'nt you just bend the legs of the fork down as I did on my FD 85/1.2L?...That way you would'nt have had to extend the "post"/lever.
If you read the thread, you'd see that Leon tried this as well, and I explained to him that it would not work because the mechanisms would then disengage as you focus the lens to closer focus distance. If you only want the aperture to work when focused at infinity, then your idea would work. If you want a fully functioning aperture throughout the focus travel, then the only way to do it is how it is detailed here. Leon soon realized that I am correct, and he did it the right way. If you bent the fork legs down too far, they would prevent the focus from traveling back to infinity again. The FD 85L is irrelevant to the discussion.
