Re-calibrating Kodak Focus

[P3D <Linnstaedt@xxxxxxx>]

Dear Colleagues,

I have now mustered the  courage to work on my Kodak Stereo Camera, to
eliminate its focusing problems.  I seek your guidance.  The camera is in top
working order, except that the focus is way off from the marks on the lens
barrel.  In use, I have stopped down (up?) to smaller apertures and
lengthened exposure, even to making 30" time exposures.

Can anyone suggest proper procedure for this fix?  I have already fabricated
a "ground glass" from a strip of 35mm film.  My plan is to mount the camera
on a tripod, the back open and the "ground glass" in the usual film channel.
 With aperture at f/3.5, a cable release will hold the shutter (B) open while
focusing.  The room will be dark except for a lit candle placed at a
carefully measured distance.  I'll wear my reading glasses so I can see more
detail in the image.  When the flame is correctly focused on the film, I will
be ready to do the next step....

But what is the next step?  I do not know the correct way to go about
changing the lenses from the old calibration to the new.  There are two small
screws on either side of each lens; do I remove these?  Should the camera be
placed in a particular position so nothing falls out?  Is there a particular
distance I should use for this re-calibration?

If someone could please help me, it night save much anxiety and/or damage.

Regards,
Robert Linnstaedt
