P3D Mounting Guides/Dali Museum/Screens

[HatfieldMk@xxxxxxx]

Dear Friends:
I have several questions plus a few observations and comments for the group. 
First a couple of weeks ago I wrote in questioning the feasibility of 
constructing my own silver screen vs. the expense of purchasing one. Of the 
responses I received about 80% advised that painting foam core board would be 
a marginal solution at best. A few of you suggested that I try a local thrift 
store (such as Goodwill/Salvation Army). I am happy to report that I found a 
50X50 DA-Lite Silver Pacer screen at the Waterfront Mission Thrift shop in 
little Ft Walton Beach, FL for $11.99! They also had a great selection of 
various old cameras and projectors, thanks to all of you for the terrific 
idea! 
Next I have a question about mounting guides. I have just finished reading 
the excellent tutorial on stereo slide mounting offered on the RMM home page. 
I suspect that the separation of the near-point vertical lines on the 
mounting guide is directly related to the mount being used. If I wanted to 
try and produce my own guide would I separate the near-point vertical lines 
by a distance equal to say right edge to right edge window separation of the 
intended mount? And if so (or even if not) what is the proper offset for the 
far-point vertical line. Finally on this subject, once the guide is produced 
can it be photocopied onto clear stock such as used for overhead projectors. 
My concern is that the copying process could produce some errors, i.e., 
either enlarging or reducing the image slightly. Your thoughts?
Finally; I have read with great interest the thread on Salvador Dali and his 
stereoptic paintings. I believe that St. Petersburg, FL has a Salvador Dali 
museum, does anyone know if the museum has either the paintings or 
publications of the works in question?
As always respectfully submitted:
Mark H
