l went beyond my abilities and opened my (rare) carl zeiss jena vario-tevidon 15-150mm c mount to spray out dust in between two of the elements just below the aperture section. upon reinstallation, one of the stationary glass elements went into a tube sideways and got stuck. (there will be three times in this order of events which you may call me an idiot. this is the first.)
I got the glass out by bending the metal tube parts so I could relieve enough pressure to pop the glass out, but of course now the threads on the metal tube aqre damaged and I cannot hold the final elemnt in this selection in the tube.
I'm fucked, what next? ive been thinking about either shaving off the mangled parts so the cap which holds the final element in place can catch something. I loved this lens, but I guess not enough to pay someone professionally to clean it for me. ive got no choice now because its become a pretty serious job

Welcome skyegreen42!
screwing into a 1" x32tpi thread-repair die might fix that. (I'm not certain that is correct thread size, but you get the idea, eh? Find the correct size die...) _________________ ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮ like attracts like! ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮
