[photo-3d] RBT/Spicer mount window differences

["John Goodman" <jgood@xxxxxxxx>]

Has anyone using RBT mount jigs for easy Spicer mounting 
noticed that the respective 5p and 7p window apertures are 
different in size? I often set the near point just inside the RBT 
stereo window but find that such chip spacing leads to a 
violation of the Spicer window in some cases.

Using the pushed out Spicer window paper chips as a gauge 
against the RBT windows, it's clear that the Spicer 5p aperture 
is wider than the RBT, while the 7p is a tad smaller. There are 
probably slight differences between corresponding window 
centers as well.

So if one is treading these thin lines, delicate window settings 
need to be previewed by laying the intended Spicer mount over 
the RBT jig, prior to transfer. Or is this standard operating 
procedure?  :>)  Of course I'd like to learn all about the origin 
of these slight differences.
