Homebrew PCBs

I'm convinced now that I should give the photographic method a try and 
even try pre-sensitized boards.  I'd like to do things the Right Way 
instead of going sloppo like I have been so far.  That might explain my 
previous problems.  Anyhow, I'll start with constructing a UV exposure 
box.  The box and timer stuff seems straightforward enough, but what I'd 
really like is to make a gizmo that sandwiches the PCB and films between 
two sheets of glass or lexan.  The idea is to put the things in this 
frame, adjust for registration, clamp it closed, and that's it.  Insert 
into the UV box for exposure.  I saw a page a couple years ago discussing 
something like this, but I can't find it anymore.  Does anyone here smell 
what I'm cooking?

I keep the boards small and one-sided, would a UV EPROM eraser work?
