Below is a tripod I'm assembling,
to support a pair of 20x90mm Oberwerk binoculars, with the help of a few
friends, Lee Younglood, Nate Perkins
and John Hartman. Thank you for your expertise fellows and the use of your shops. These images are intended to be 3D sets. If you set back about 3'
and focus on the right image, cross your eyes a little, then reduce the distance to the images, they two should converge into one 3D image.

This tripod will .
Here are most of the parts for the tripod itself, except the counterblance group. On the left are three oak legs ripped down the middle, the brace with three
stabilinzer arms is to the right, below is the collar that holds the brace in place, top platform & centerpipe, rotator cylinder are to the right, the legs are
screwed to the 7" thick circle with the three tabs. The adjustable mount to which the binoculars will attach . And of course the aluminum tubing that will
make up the arms of the parallelogram itself. I have changed my mind about using two 45 rpm records to provide smooth rotating surface, the surfaces
of the discs are very smooth and hard and with a little paraffin, should provide low friction surfaces for easy rotating.
As of April 07, 2009, this is as far as I've got. now I can work on the top part that carry, aims and translates the bincoulars, the arms will beGetting Closer: (April 12, 2009) Happy Easter all
constructed of 1" square aluminum tubing, the counterweight will be a 7.5 weightlifting weight.
On the cosmetic side of this construction, all edges and surfaces were sanded smooth to the touch (no splinters here) and old varnish removed.
The final exterior will be a light walnut color, think I'll keep the arms their metal color.
3D View: This is the 'squareing' jig. Dreamt up to make sure that the pivotblock and the parallelogram arms are square to each other. They may not be exact, but pretty darn close. The 1" aluminum tubing is level & evenly spaced. It should be possible to make out the centered bubble in the middle of the level. The T-square made sure that the pivot block was perpendicular to the arms. And I measured the angle of the pivot block itself, to make sure it was exactly square (90*).Completion So Far: April 11, 2009
