Thank you Carl - these videos are absolutely fantastic (as is the print material of yours I've found on the web). I bought an old BH-2 yesterday. As expected (and advertised) it has lots of potential but needs some work. Thanks to your videos I've already taken the field diaphragm adjustment ring from seized and immovable to silky smooth and like new. The head retaining pin is moving freely again (blimey that C clip is tiny - was very pleased to have that safely back in place!) The trinocular head is also seized absolutely solid so I have a longer and more challenging job there - but I'll do it. It is a joy to work on 1980s Japanese engineered kit - so beautifully designed and built. Many thanks for the tip about JIS screwdrivers - that explains a lot - I have a set on order! I've spent years using old scopes and have just put up with everything being a bit stiff. I think those days are over - now everything is going to be moving freely! If someone could just do a comparable series on the SZIII life would be absolutely perfect! Many thanks again Ian
As a postscript the trinocular head is done and working, scope is all in one piece and first results look pretty good. The phase condenser is next for the treatment. Without your videos I wouldn't have a functioning BH2 which I have the enormous satisfaction of having bought back to life. Thank you!
Awesome. Thanks! As far as cleaning the parts, what can be cleaned in an ultrasonic cleaner and do you have a suggestion for a cleaning product? (I am going to guess just Dawn or similar).
I use an ultrasonic cleaner for some parts. Simple Green works well removing the dirt and stuff from the focus knobs. The old dried grease is very stubborn. I sometimes run the brass gears and focus rack through in a small glass bottle of acetone. Even that won't remove it, but it loosens it up nicely.
Thanks so much for the video, very helpful. What should I do if the interoccular distance mechanism is totally seized and I can't slide it apart to access the screws?
Have I told you lately I love you. Taking a part my scope to salvage it after an accident. You are my RUclips hero.
This is a perfect example of how a step-by-step repair course should look. Thank you! You are a national treasure Carl!
Thank you so much for doing this Carl! We Olympus BH2 user community are very lucky to have someone like you!
