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. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
