OK but no one (on-line at least) has really put together a step-by-step on 
how to calibrate a camera rangefinder. The link is a good start but there 
are a lot of points which could be covered in more detail. Clear agreed upon 
definitions of parts involved would be a good start.

  You need to adjust the length of the arm. A general discussion can be  
  found here:

  This photo shows the infinity eccentric but you can also see the  
  eccentric at the pivot and the two arm travel limit adjustments:
