Oleg:

Got your message about the 2 1/4 twin rig cranking solution.  That's a usable 
idea.  So I investigated a little further; I have a Rolleiflex TLR. with 2.8 
Zeiss lens, to put two side by side the stereo base is 100mm, which is good 
for most cases.  I tested the 6x7 with 55mm lens, set to 70 mm separation 
(film deviation 1.2mm) and 140mm separation (film deviation <2mm), very 
viewable in both settings. So the Rollei's 100mm is OK, but how to sync the 
shutters is still a problem.  

I checked out e-bay to look for a Rolleiflex to match mine (just for fun, 
don't want to buy another one yet), but it is very difficult, since mine is 
very unique, it can use 35mm film as well as 120, but I don't have the 35mm 
adopter.

As for the progress of the 6x7 3D viewer, I am gaining ground.  I made two 
slide holders.  One for landscape setting, and one for portrait setting, and 
the lenses I have can cover both of them nicely.  By George, I think I got 
it.  I am going to make a prototype box with heavy card board first, and make 
improvement as I go along.  I can build a light box like those I've learned 
for the MF-3D list. Or I can buy one from B&H, but they don't seem to have 
one to fit my size, I needed a 3"x6" light box with DC operation.  More info 
later.
