Binochair prototype is finished

The parallelagram arm was made using a LCD swing arm
It works quite well but I do need to make the groundboard larger. With the bino's mounted it tends to tip to that side when I'm not seated.
The LCD arm works very well as a raw parts deliverer for a P-mount.

Perhaps a lump of lead or similar on the opposite side of the base board to the bino pillar might prevent the tipping and give you smoother azimuth?
10 out of 10 for Scrapheap challenge use of the LCD monitor arm for the parallelogram arm.
Is the tilt of the chair fixed? Are you considering making it variable and linked to the binos?
I am very impressed.

Instead of a larger groundboard, how about some ballast? Maybe a heavy plate (steel) for a weightlifting set under the center of the chair would keep it level whether you are seated or not. Just an idea.

I found I had to add a wider triangular frame (37" per side) out of P.T. 2x2s for the groundboard assembly on my binochair to keep from tipping. Now it's completely stable.

The problem with the counterwieght is that by back schreems every time I lift the thing in and out of the car.
The arm was purchased from Conrad Electronics here in Germany (www.conrad.de). I do not know of a US source.
The back of the chair of fixed but I've modified the angle and have the movable pillow. It is fine from Zenith to about 25°. Below that the skies in Germany are unusable to I'll stay with that for now.
Now all I need to do is make the thing lighter and maybe lengthen the P-mount arms a bit.
FORTUNATLY I will not be able to make the needed modifications soon :-)

Congratulations on the new addition to the family. (Another 3kg counterweight?) No wouldn't be very stable.
Before you know it she'll be wanting to look through those binoculars.

I could knock together a binochair given enough time - but you have received a greater blessing in your daughter than I could ever hope for for myself. May you find peace and joy there.
