I'm looking to build my own parallelogram mount for a tripod I have (Benro KH26NL). Does anyone have any suggestions on designs, how to go about doing this, etc.? The maximum weight on the Benro is 11 lbs., is it reasonable to build a p-gram within that weight? I came across these plans, which is generally what I'm looking for, though I'm open to ideas.

The parallelogram puts most of its weight off the side of the tripod so the load rating of tripod shrinks a lot under that (even when a counterweight rod is added). Based on the companies who made those things that we used to sell I am thinking that tripod is way too light. Most of my tripods are Bogen 3021/3221W which have a 13# weight limit and I consider those too light for my heavy Vixen 11x80 binos.

That's a very light tripod for a parallelogram.  Just a p-gram and its counterweight will be pushing its capacity even before you've added the binoculars.  You'd have to have a very light setup indeed.

 

Weight adds up fast with a p-gram + CW; it will substantially exceed the weight of the binocular.  I strongly suggest a higher capacity tripod if you're going to the trouble.

I use my p-gram mount with Vixen 20x80's on an old CG5 tripod - the ones with 2" stainless steel tubular legs.  stable as a rock.

I use a surveyors Tpod. With my P-gram, 20x80 Oberwerks, and 15 lbs of counter weight, it holds the approx 25-30 lbs very well.

Here's some info on a home brew Parallelogram that's easy to do:

 

- Oak 1" x 2"  (3 or 4 6 foot lengths)

- Two Upper LONG bars are 38" long

- Two Lower Short Bars are 18" long

- Pivot Vertical post is 12" long & made from two 1"x 2" pieces

- Bino Vertical post is 8.5" long & made from two 1"x 2" pieces

- 1/2" Nylon Spacers between long/short bars and vertical post

 

- 1/4" x 4.5" bolts with LOCK Nuts adjusted to allow movement without slipping + fender washers.

- Kmart 5 lbs. Barbell, postion and type can be customized.

 

-Bino wood hinge allows left/rigth & up/down movement of bino with adjustable friction to limit movement.

 

- The bino's.are 10x42 and are not too heavy.

 

The Parallelogram works very well and the Oak makes it very strong.
