I occasionally have had problems folding the camera, because the cam under the
rails got out of line. The solution was just to push it over an little with my
finger.

Thanks I got one with a 35mm hole when I got the camera because it was all
they had, and I bought it just for that reason, a pattern. Paid about $40
for it too and bought a 42 mm hole saw. It very well may be just yarn after
I have seen the emails, and the consensus seems to be it would do no harm.
Even if it did, it doesn't seem like there is much of a danger if any of
doing any damage that would take this from a usable camera to one only to sit
on a shelf. That was my concern, and its readily apparent my experience with
this type of equipment at best would be called limited. Trying to think it
out before I act in haste.
Thing is I might have a sheet of aluminum already on hand that is the right
thickness. If so this might be easy to deal with. Everyone has been helpful
and its appreciated

Igorcmaera.com <http://igorcmaera.com/> lists a Tech III board (with a 50mm
hole) for $40. You might get that one and use it for a pattern (if not for
your existing lens).

Myron you can send an attachment to me, but I doubt the list would appreciate
it. I suspected the one I got was for the IV, or maybe even later. It
definitely wasn't for mine, and I had to make the call without even a view of
the back. Probably should have just passed.
Probably a lot of things that would work IF push come to shove. Anything
from flat black yarn to really thin weather stripping might work as a light
trap IF it was a problem. I am not sure it would be at all. It may not be
rocket science, but to me its still new. Thanks everyone.
An extra thanks to Richard that takes the time to make this resource
available to all of us

... Mine is the III version 5 ...
The lens board I thought I found isn't the right one. It is slightly wider
so it won't fit in the standard. More importantly instead of a recessed
ring cut into the back, it has a protruding lip rising from the back. There
are a couple other minor differences.
I used to own a III, and currently have (on loan from my friendly X) two
lenses mounted on official Linhof III boards. I also have a home-made lens
board I used on the III for a 360mm TeleXenar. Plus a couple generic boards
that fit the III. The official Linhof boards have a slight indentation or
machined depression to match the fuzzy light trap material surrounding
opening on the Linhof. The others do not. All worked in all kinds of lighting
conditions.
The protruding lip you describe appeared with Model IV, and fits *into* the
Linhof opening. The III lens board depression matches the fuzzy material
*around* the opening in the III.
I made several model III lens boards from flat pieces of aluminum, using only
hand tools and flat black paint. They all worked in Arizona summer sun and
Ontario sunny snow. No fog, no leaks. Look at some of the Japanese wooden
cameras. They often get by quite nicely with flat lens boards and nothing in
the way of a light trap around the opening in the cameras.
... There does seem to be some sort of soft material that is around the
lens hole in the front standard that seems to match the ring cut in the back
of the lens board. Feels like a felt like material, and it's not thick at
all. I am sure a flat board would work, at least at first, but would it
damage that material?
I’m not sure what you call that material, but it isn’t magic. It’s just
black, opaque and compressible. Black yarn or string of an appropriate
thickness would probably work. But in my case the original material did not
seem to suffer from my totally flat lens boards. The boards do not fit so
tightly that they apply much force to the “light trap”. If you fret about
it, you could simply use contact cement to attach black cotton or linen cloth
to the lens board around (outside) the ring where the depression/ring is
machined on the official boards.
Can we send attachments to the Pure Silver group? If we can, I can attach
some photos of my lens boards.
I’ll check my supply of light trap material for fixing light leaks in elderly
cameras (like Nikon F or Pentax 67).
