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
To start. Would cast Iron be a plausible candidate?
