Monitor Swing Arm Bino Mount
Posted 11 August 2005 - 04:21 PM
It arrived today in one piece. It has a couple of small nicks on the base, but is in pretty good shape after it's trip from CA. It's heavy, maybe 15 lbs +/- and very solid. thick metal and clamps to a table very solidly. I was hoping the arm would have vertical capability, but it only extends sideways about 21" and pivots in azimuth. It will hold 55 lbs. so my 8 lb. binos will be like mounting a feather on it. The tray and it's azimuth pivoting arm will unbolt from the main swingarm.
I'm think of mounting it on a pier next to a turntabled chair. The arm would move to the observer from the side. So the problem is how to modify it to get the bino to move up and down enough to look to zenith and down to the horizon. Stay tuned as I rack my my brain for ideas. I'm open to suggestions also.

...but without the little pivot piece on the bino "L" bracket.
I calculated the P-mount's vertical travel to be around 9 1/2" which should be enough to raise the binos' EPs for zenith viewing. I think the short booms and "L" bracket will be sturdy enough to hold 8 lb. binos. Design variances could include longer booms on the counterweight side of the P-mount to reduce the amount of counterweights. If more height is needed, increase the vertical spacing to 5" between the booms or increase the boom length on the bino side an inch or two. I think this design could be adapted to a Bino Pod or Bino Bed style turntable. I think the Bino Bed would work better since a shorter pier could be used.
While this design is heavier than my current Bino Bed mount, it's 55 lb, capacity means 10 lb. and larger binos could be used which is more capacity than the wood mount I use now. Don't really need a mount like this since I my heaviest binos are 8 1/2 lbs., but for those with lighter 100mm binos it's a possible mounting alternative that could be very stable. This is going to be an interesting weekend in the basement. Stay tuned for more bino mount madness.

Here's a plan of what I had in mind.
