Hi all,I've built a parallelogram mount for my celestron badged Vixen 20x80's which I must say are an excellent binocular! the problem I'm having is with the axis where the binocular pivots up and down.
I've used a 6mm bolt with large metal washers inbetween both pieces of oak to secure it to the bars with a spring washer and self locking nut.
I tighten it up so that the weight of the binoculars do not make it slip when tilting the handle assembly but when you move it up and down a few times it becomes loose,what do others use to combat this problem?
Do you have to leave the whole handle assembly to be able to move freely and then balance the binocular using the built in bar to address this problem?
any help and advive would be greatly appreciated! please see attached photographs.
