On my computer screen, I google up APUG and am brought to "todays posts" Despite all the categories I could select as a preference, I assume that any post in any category appears under "today's posts" for the broadest appeal, and presume from that we are all on the same page. That is my intent in the starting of this new thread; that I may hear stories and glean a procedure to deal with separating lens elements. For my purpose I bring up a Hasselblad 80mm lens in the old silver barrel where the front 2 elements are cemented. Being a world class do-it-yourselfer, I dare to think I could get those 2 elements apart, clean, and re-cement them. Right now the lens in my mind has separation on the outer 3/32 of the group. Ideas? Thank you.
