How to cut a mirror?
Hi there, I'm attempting to replace the frameline mirror in my Bessa R3A. For those who aren't familiar, inside many rangefinders is a mirror that is angled at 45 degrees to the frameline image and viewfinder. This mirror reflects the framelines into the viewfinder. I have a couple of spare mirrors from broken cameras, but I can't seem to cut these to the right size. The problem is that it's only about a centimeter tall and 3 centimeters wide, so attempting to score and snap causes them to shatter. Moreover, the mirror has to have a hole in the center to allow the rangefinder patch into the viewfinder. Any tips? Perhaps a cheap rangefinder camera you know of has a similar type of setup?
