I was given an old pair of Bausch & Lomb 6x30 Zephyr binoculars by a friend (similar to the ones in the picture I attached). The optics look fine, but the focusing mechanism is stuck. I sprayed a little WD-40 on it, and managed to get the focusing knob in the center to turn, but it just screws off of the focusing mechanism and doesn't change the focus at all.
I don't believe that they need any repair to the optics, just the focusing mechanism in the center probably needs to be disassembled and lubed. I tried to get at the focusing mechanism from the eyepiece side, but I think that you may need to unscrew it from the objective side which has a cap with two holes in it (see attached picture). Does anyone have any idea how to disassemble these things?
What you need is called a spanner wrench, it is basically a flat handle with a U shape at the end that has two small (hardened steel)pins that protrude from the legs of the U. There are many different sizes and they are usually sold as specialized tools for a certain application (Bausch and Lomb techs prob. used one to assemble your bino's). The cheapest alternative is to find a pair of 90 deg. snap-ring pliers that fit the hole size correctly, the pliers can be opened or closed to the correct distance to fit the holes. Be sure to hold pressure on the top side to keep the tips from trying to push out when you start turning on it. FWIW, the one-piece pliers work much better than the one's w\interchangeable tips.
All I'm going to say is that the tip of the rocket is going to be placed along the natural flight plane for a small dog. This will place the tip of said rocket just below the tail of this yapping, shivering, near hairless replica of a real dog. Let's see how he survives outer space with less hair on his body than I've got on mine!
Well this thread is certainly going places I hadn't planned, ....
Back on topic though, has anyone actually ever opened a focusing mechanism like this? I can probably figure out how to get the thing opened using the toolman's advice. I just want to make sure I'm not going to get into trouble once I get it open.
Good luck w\it, after you get the cap off, you might want to record the number of turns it takes to get it apart. Sometimes these are timed so the travel will be correct, it just depends on how it's set up.
the threads around here can tend to wander but it usually ends up with a good answer.
i try to keep folks on topic but you know how it can get.....
My view is you have led threads off ***by the way,did you see where Tom Cruse is building a bunker to keep aliens out.I never got it straight if it was illegal or outer space.Will check the web.To stay on topic try getting B&L on the web.They might repair them. sam.
Yeah, I thought about sending it to B&L, but they don't build or service Binoculars anymore. I'd have to send it to Bushnell (I believe B&L is or used to be a parent company of Bushnell).
Also, I don't have a warranty statement for the Binoculars, and so I don't know what's covered, and the only warranty info I can find for B&L binoculars is for a newer model. It's a limited lifetime warranty good for the lifetime of the original owner, and since my buddy picked these up at an estate sale...I'm pretty sure that they're out of warranty (but, I don't have to tell Bushnell that I'm not the original owner ).
Anyways, it would cost me at least $10 + shipping to ship them to Bushnell, and I'm not even sure whether they would repair them for free under the warranty. Plus it's a 6-8 week turn around on the repair, and I was hoping to take them with me when I go deer hunting this fall.
Besides, I've always had the mindset, of why should I pay someone to do something I could do myself for free.
