I have a pair of inexpensive 10x50s that were given to me. The problem is that the EPs are no longer connected to the focusing shaft. Can these be easily fixed or would you recommend disassembling them (the objective barrels easily unscrew) and rebuilding them in another way?

Charles,
both arms are broken. Spare parts are most probably not available and such a repair doesn’t make sense in a so cheap binocular.

this may be a stupid idea but i havent had time to think of a better solution, seeing as these are cheap and currently useless, you could try epoxying the eyepieces permently in place focused to infinity and use them for astro only or long distance terestrial, you'de have to do it at night when its clear and use a star for focus or the moon and use a half hour set epoxy and keep them aligned and focused as it cures... just a thought mind

maybe it would be possible to use some electrical tape wrapped around the tubes the ep's slide on to hold them semi firm and just push and pull till focused, once positioned you'd need to be gentle with them but it should work for long distance and allow you to adjust them still. it would need to be a tight fit

I still have decent (and FREE) 50mm lenses I should be able to use for something. All I really need to do is to find a way to get the EPs to move with the center shaft.

JB Weld is another good repair compound for something such as this perhaps?

i dont think you find a glue/epoxy or any adhesive that will be strong enough to fix those broken ep arms, they'll just keep snapping.
it may however be possible to make a new arm with plate alluminium but the ipd would be fixed

That sounds good. They are quite light-weight and FREE, so I hate not to use them. Thank you.

I was thing of something similar. I am going to take them to Lowes today and see what I can find to attach them to the focusing shaft. The shaft doesn't turn, so maybe I can "bolt" them to it.

Yes. Surely, there are plenty of ways to make to peices of plastic move up and down.

The picture shows how the two arms should be rebuild in a binocular of some value.
The gold coloured part is the prosthesis, it should be made possibly with brass and glued with UHU Plus epoxy adhesive. Then some rivets (red coloured in the picture) or screws (thread 1,7 or 2,0 mm, conical head) should join for good the two parts.

Think about it guys; this is NOT just an issue of FOCUS. We're overlooking the "C" word again. A third of the optical train is attached to these two bridges which are decidedly out of collimation.
The simplist LASTING fix would cost MUCH more than a NEW bino. FREE is only a good price if it comes attached to a serviceable instrument.
Just a thought.
Cheers,
Bill

you could just make a finder scope useing the objective some plastic pipe and a 25mm ep, thats what i did with a broken pair of 10x50's keep the other side as a small spotting scope/monocular, use the right diopter to focus and just epoxy the thing on....?

Free can be good if something can be serviceable with little expense. If someone gave you a free truck that did not run, but you can get it back into good service for $400 or you can buy a similar truck for $1500, then you have a decision to make.

If I knew as much about vehicles as about binoculars, no I would not take the truck. But go ahead if you must. Experience is a great teacher. It can also be VERY costly and time consuming.
To each his own. We'd all be glad to hear how it turns out.
Cheers,
Bill

I will. I am not going to spend over say, $10 or so. If is is more than that, I will use the lenses for something else.
