[LargeFormat] Deardorff black stuff

[Karl Faller]

Craig,
  Presto Felt by Kunin Felt, Hampton, NH 03842.  Your camera is a Folmer 
Schwing.  I have just replaced the light traps on a 12x20 and it is 
neccessary to rout a channel about
1/64" deep by 1/4' wide in the back of the lens board frame to accept 
the pressure sensitive felt.  There are three, two at the top and one 
at the bottom each about 1/16" wide.
Check a fabric store near you for felt. You may find some that does not 
have glue on the back but is tougher than Presto Felt.  If so, use 
contact cement before you cut the 1/4" strips.

Steve,
Since Steve's camera is a Cambo (a metal Camera) the camera is probably 
not warped or bent so It would be wise to check the holders for the 
light leak.  If they are warped
(sight down all four sides of each and or lay them face down on a 
surface you know to be flat and try to move them up and down... get the 
picture?  Light leaks are a touchy
problem, difficult to discern via email.
