[LargeFormat] Film holder question

[Les Newcomer]

the locks on the plastic film holders aren't a thread they are sort of a 
knurl(actually concentric rings).  They are pressed in the plastic when 
the plastic is warm and the plastic "heals" itself.  Thus they don't come 
out. Once pulled out you'll be better off with a two part epoxy than paper 
because you'll have to replace the plastic that held it in in the first 
place. The problem with the epoxy is whether it will let the lock rotate 
after it set up.

The suggestion that  they (the people who make all of the film holders in 
the US) told me was maybe a warm or low temp soldering iron could move the 
plastic back around the lock.  I bought several 5x7 film holders on ebay 
and found that some masochistic dental trainee had ripped all of the locks 
out.  I was able to aquire a few extra locks but have yet to find the time 
to fiddle with that project yet.
