"Sandy's already sent you some info on this, but I think the  confusion
may be between a vacuuum frame and a vacuum easel.  You may be  thinking
of something that holds a piece of paper flat, either for  rephotography
or for enlarger work."
 
               
                Eric... Yes!   You hit the nail on the head.  That's where i 
was confused!
 
"A vacuum frame is a hinged piece of equipment, with a sheet of  glass
facing up and a rubber membrane (usually called a blanket) at  the
base.  The sandwich of negative (or positive) and sensitized  material
is placed on the rubber, the glass cover is brought down, and  the
vacuum pump is turned on so that it sucks out the air between the  glass
and the rubber, ensuring very close contact."
 
 
                    Ahhhhhhhh  i see!  Knowing that, along with what Sandy 
said 
                    about large negatives  and diffused light sources ( both 
of which 
                    i  will have ), i realize now that i DO need a vacuum 
FRAME. 
 
The  next question i have of course, is can i build it, or will i have 
                    to,  ....gulp...., buy one?  Seems i could use a large 
vacuum easel
                    and  add a glass frame hinged to it.  Would that work?
 
 
 
whew... thanks so much.
