Gosh I LOVE this group!! I am off from school right now but can't wait to get into the darkroom Monday & experiment! Snoopy, the reason for wanting the lenses to face front is that I'm teaching a bunch of high-school students. We are getting into fine-tuning prints, and I think being sure what aperture they are using is getting in the way of most of them. Richard, most of them are omega C700's w/condenser heads. And a Beseler or 2, not sure of the model. I cannot get the lens to face front on any of them. Thanks for everyone's advice & comments.
