Hi guys! I'm a recent convert to Russian rangefinders and must admit have been trolling in this forum for quite a while!
It's just too damn good a source of information!
My first FSU camera (otherwise known as crack in camera form!!), a fed 3b arrived last week and I've been tinkering about with it since. I've managed to calibrate the rangefinder at infinity and cleaned the lens so far. My problem is this:
After reading the fantastic guide to relubing these interstar lenses by Matt Denton, I decided that I was probably not *that* confident with my repair skills yet so I went as far as removing the focus ring and cleaned off as much old grease as I can. Then I had a inspiration and reached for that ever trusty can of WD40. Indeed, with a small squirt of it the focus ring started to move like an eel in a waterpark!! I careful reassembled the lens and put it back onto the camera. Now the focus is working much better than before but It's a LOT stiffer than it is when NOT screwed into the camera. i.e. it turns but needs a bit of effort. I'm totally baffled by why this is. Any suggestions? As far as I can make out the usage of WD40 hasn't affected the focussing movement as it still moves smoothly when not screwed in.
Just a word of warning, I have a fed5 winding its way to me too so expect lots more stupid noob questions!!
