Homebrew PCBs

  I remember seeing a setup (I don't remember what it was feeding, but 
it was flat plates of some kind)  
where the plates (pcbs for us) had 2 plastic strips connected across all 
of them.  The strips had the
appropriate holes for the old tractor feed mechanism.  The strips were 
folded between boards so that it
stacked and feed like paper - except it did not bend in the middle.  The 
proof of concept is out there.
The question is where to get the plastic stripping.  Vivisimo.com search 
for "tractor feed carrier" came
back with:

They sell something that might work.  Tape strips, 3.125" by 1296" (108' 
should last a little while), 2.5"
center to center on the tractor feed holes.  Chop it in two, put it on 
the sides.  I'm guessing alignment would
be an issue unless you made some kind of a gig for aligning each board 
to the last.  It would probably be
either capital or labor intensive.
