Binocular parallelogram mount

Introduction [ edit this section ]

This parallelogram mount is for binoculars with a front 1/4"-20 mount, Celestron SkyMaster 15x70s in this case.  It has five degrees of freedom, and the binoculars are well balanced.  The height is for standing children or sitting adults.

I made it from scrap parts I had at home.  

There are many variations possible.

Notable parts:

  • Four cherry strips for the horizontal sections.  These are scrap wood from a discarded crib.
  • Paired strips of 1/2" Baltic Birch plywood, laminated together, for the upright members, for the semi-circular binocular holder, for the azimuth rotating section, and the leg attachments.
  • 1/4-20" knobs and carriage bolts from Amazon
  • Bondable PTFE pads (from Amazon) bearing against CD inside the azimuth rotating section
  • PTFE washers inside all the rotating joints
  • PVC tube legs
  • Webbing for making the legs not go far apart.


Some construction notes:
There is a section of 1/4"-20 threaded rod with a glued-on knob that mounts the binoculars to the semicircular section.
All the circular and semi-circular portions were cut with a router.
The very ugly counterweight is sand inside a bubble-wrap envelope.  There is good reason for it: it's so that when one kid is moving the binoculars, other kids who might be near the other end don't get too badly hurt, as they would if there were a hard counterweight.

Enhancements:
Since the pictures were taken, I strengthened the central upright with additional oak pieces to make for less torsion.
