Feeler gauge is exactly what I was thinking - the flat blade type, not,
obviously, the wire type. The flat blades will give you some pretty
thin options.

The problem is that the ball bearing is held "high" by a spring beneath it.
You must compress the spring so the ball bearing is low enough to slip
the aperture ring over.
Now imagine trying to keep the ball bearing "down" as you slide the
ring one. As you slide the ring, whatever you were holding the bearing
down with is in the way. You need something stiff and THIN that will
be strong enough to hold the bearing in, and yet thin enough that you
can pull it out from between the aperture ring and the lens when the
ring is *in place*.
Haven't figured out what that stiff thin thing is yet and I have a
couple of repaired lenses patiently waiting in baggies for me to
figure it out.
The first thing I'd think of trying for "stiff and thin" (quiet, Larry!)
would be the blade of a spark plug feeler guage.
