I have a set of Nikon Sporter I 10x36 binoculars. The center hinge is so loose that I must constantly adjust them to keep the separation to match my eyes. How can I tighten the hinge so that it does not move quite so easily?

Simple solution: Pry or unscrew the cap covering the end of hinge shaft on the rear of the binocs (between the eyepieces). Use a screwdriver that fits snugly in the slot on the end of the shaft & tighten to desired tension. Place a dab of Goop-type cement on the inside of the cap if it was pried off & press it firmly back on the shaft . Helpful hint: Slide a small knife blade (an old dull one you don't use for cutting) under the cap and gently work your way around to pry it off. Note the position of the index numbers before you remove it so you can replace it in the same position.
Does this pair have two parallel tubes with a bridge in between?
If it does, then removing the caps at the eyepiece end of each hinge will reveal a grub screw. Tightening these will add tension to the hinge and give you the proper feel once more.
What an excellent glass you have. Nikon in your country should have a service center. I have had them get me a replacement set for a 7x50IF SP WP which is not a common model. They emailed me an order form and I emailed it back. They were not in stock so it takes about 6 to 8 weeks. May I suggest you order a back up set when you do.
If they aren't too helpful (they needed a shove) try Binoculars.com or Adorama Camera in new York. They will also ship internationally.
they were famous for that, because the screwpin that holds the eyepice shaft is metal and the groove that it rides in is plastic, and eventually gets jammed....look where you put your fingers to adjust eyepieces. should be small metal plate in center of hinge(sometimes with bushnell logo) that will simply pry off by using small screw driver,and now you will be able to see if the screw is loose or damaged. good luck...firstname.lastname@example.org
first open and close the binoculars untill they fit you eye width,now adjust left eye with the flat section located on the center hinge,now turn right eyepiece till clear. note: once you have adjusted right eyepiece you only have to leave it in that position in order to focus from near and far.........good luck......email@example.com
on some models the center focus control is located on the center hinge,it should be flat,and not hard to find,if there is no center wheel this is where it should be...good luck...firstname.lastname@example.org
I agree with you on that! I have a feeling they are either Nikon or Leupold sourced. The body is alot like green ring leupold ive seen but the lenses have a magenta multicoating on a lens surface which ive seen on nikon. I'm in the process of looking for the maker of them myself as I need an objective lens. I'm going to call the Cabela's Cust SVC number and see what they say. I've heard the new Euro styled binoculars are made by Meopta.
