Home made binocular support – cheap and easy!

Hello,

My wife’s Leica binocular does not have a ¼ inch threaded socket for the typical binocular mounting post, for mounting the binocular on a photographer’s tripod. I had a look around the web for alternative mounting devices and all I came up with was a Leica model that looked quite bulky and cost a lot too!

So, using a few bits and pieces, I made my own:
  • 1 ¾ inch length of 70mm diameter PVC plumbing pipe.
  • Aluminium bar 4mm (T) x 25mm (W) x 85mm Long.
  • A strip of 1.5mm closed cell foam.
  • Blind rivets – 4 off.
  • A dab of contact adhesive.

As a picture is worth 1000 words, I’ll let the attached photos do the talking.

Some key points are:
  • Angle the binocular support cups, if the bino optical tubes are tapered.
  • Make the mounting plate 4mm thick to recess the tails of the blind rivets.
  • Fit the domed, shallow rivet head on the inside of the binocular support cups.
  • Glue a strip of 1.5mm closed cell foam strip inside the binocular support cups to cover the rivet head and provide a cushioned surface for the binocular optical tubes.
  • Trim the two binocular support cups from semi-circles to crescents as per the profile of your binocular optical tubes.
  • Use a continuous length of Velcro strip sandwiched between the binocular support cups and the mounting plate, held in place by the x4 rivets.
  • Place the soft, furry side of the Velcro on the inside where it contacts the binocular body.

The support is mainly for bird watching, although I suspect that it could be used for astronomical observations up to around 60 degrees altitude.

Cheers

Dennis

PS – the unassembled version in the series of photos is the prototype that I built before completing the final model with a 4mm thick mounting plate.

Good solution Dennis. I have an old pair of 7x50s also without a mount point. I came up with a very poor solution. This is right on the money! Thanks!

Thanks guys! Just an additional note – if your binocular optical tubes are longer than ours, you might benefit from cutting a longer length off cut from the 70mm PVC pipe. This should provide more longitudinal stability.

Also, the 70mm PVC pipe had an ideal circular cross section for our Leica 12x50’s. I believe you can get different diameter pipes if your binocular optical tubes are of a lesser or greater diameter.

Another possible design improvement might be to use a strong rubber band and clip rather than the Velcro strap, although we’ve found that by setting the binocular interpupilliary distance first, then clamping the binocular in the holder second, seems to be a suitable approach. We both enjoy the same settings as our eyes are the same distance apart – oh bliss!

Cheers

Dennis
