Donald Clement asked:

I'm going to use a camera shutter release cable in a foucault tester. Does
anyone know the diameter and thread pitch for the connector on a typical
35mm camera shutter release cable? 

I cannot tell you the exact thread size.  But I can tell you that it is no
standard thread.  The threads on a cable realease are tapered and coarse.  I
do not doubt that you can jury rig some acceptable threads through a small
hole in 1/16" thick metal.  Or do as I planned:  run the cable release through
a drilled block ( mine is a 3/8" bar stock) and hold it there with a set screw
tapped into the side of the block.  That will allow you to more carfully set
the position of the release.
