I pulled my old early-70s Sears MIJ 7x35 binos out and, frankly, have been having more fun with those than my Nexstar 4se over the last few months.  I decided to try to attach it to a camera tripod, so I ordered a Barska binocular tripod adapter and, well, it won't screw on. I suspect that sometime in the last 45 years, the standard thread changed, but maybe I'm being a true noob and missing something obvious - any ideas on what to try next would be appreciated!

Perhaps give this one a try?

It works well enough for my Maven B5 15x56.  I am sure it can handle 7x35's without breaking a sweat.

Any chance that one side or the other is metric?

Even on Asian binoculars the tripod thread is 1/4 20. However the 7x35's might not be tripod adaptable via a threaded access as only larger bino's were threaded that way. That item from Amazon looks like your ticket.

1/4 20 is the norm. There are a few binoculars that have nonstandard threads. Suggest going to a hardware store with your binocular to gently try a few different threads to see what fits.

Thanks all - I added a couple of photos to my original post. Is it possible that this brass piece is some kind of adapter? I'm tempted to take a flathead to it, but I really don't want to disassemble anything I don't need to.

 

Good suggestion on that other style of mount. Seems to be overkill for my little 7x35 but it would certainly work.

is it just me, or is there no fillet in the hole?

No, it is only a screw (drilled to get inside the mechanics) that is used to adjust the hardness of the rotation for IPD.
You can take it apart and thread it at 1/4" and then use your tripod adapter. That would be a solution.

If a 1/4-20 bolt won't go in, go smaller, try a M6 bolt just to see if that works - the difference in bolt diameter is small (approx .230" for the M6 bolt,  .240"for 1/4-20 bolt and the thread is different but that might happen. Why do bino's have a  1/4- 20  bolt size for a tripod mount in the first place when the rest is metric? Left over from tripods of the past century?  Pat

Looking at your photo's, that hole has no threads at all and so not designed to take a tripod adapter. If it's close to .25" you can possibly thread it but it was not designed for the purpose of threading an adapter. You may weaken the joint. That Amazon item still looks like the ticket. I might even get one myself :) 

 

Here's an additional one

The US was once a colony of Great Britain.

Great Britain is an island and what is now called England was still a Roman province a few centuries ago. The only area that was actually conquered from the empire, and the rest of those islands are still "pure" ... as far as I know.  

 

But then there was also the war of independence ... smirk.gif

I have a section of 1x4 wood about a foot wide that I stuck a 1/4-20 tee nut on the top of the board with a through hole at the  center to mount it to the tripod- it has 2 small stubs  that allow me to hold any bino  smaller than a 70mm  by winding a inner tube bungee over the top of the bino. Cost nothing but scrap and a tee nut. Works fine on the smaller., less weighty stuff.  Pat

Well, dang. I took a magnifying glass to that hole and you're absolutely correct. Looks like I'll be sending that one adapter back and getting one of those strap mounts!

 

Thanks all. I've just processed the return - now need to choose which alternative to go with.

Some binos just don't come equipped with a threaded hub in the hinge. frown.gif

 

Another adapter that looks like it could work is the Nikon #7806 "hinge clamp" adapter that's made for some Nikon Porros but fits others as well.  You'd have to verify it fits the hinge diameter of your binos and that it allows sufficient IPD range / body clearances to be sure, though.
