I haven't gottena all of the particulars worked out yet, but I am
working on designing a camera stand and trying to decide on the best
material to make most of it out of.

I'm not trying to reinvent the wheel, but a special project makes it
necessary to be able to take a series of as many as 180 equally spaced
photos across a 45° swing and be be able to do the same again without
any perceptable deviation.

In other words if I take a picture at 12-1/4° and then continue
turning the camera all the way to the end, when I return the camera to
the same spot I took the photo I will need to be able to stop and lock
the camera so that the photo next photo I take there is *exactly the
same as the previous one I took.

This is not plausible with conventional camera stands. So I'm trying
to decide on the best metal to make the moving parts out of. A metal
that will best retain it's dimensions under changing temperature
conditions.

To start. Would cast Iron be a plausible candidate?

Thanks.

A Haas indexer would do the job nicely.

And you can program it to whatever positions you need.



The methodology of the left has always been:

1. Lie
2. Repeat the lie as many times as possible
3. Have as many people repeat the lie as often as possible
4. Eventually, the uninformed believe the lie
5. The lie will then be made into some form oflaw
6. Then everyone must conform to the lie
