P3D contact printers, was B&W slide machine

In digest 3609, Nick Merz writes, in part:


<<....  However, I can imagine building 
something that might do the trick...
[snip]... then is to build some kind 
of a light box that allows me to sandwich the exposed and unexposed 
rolls together and expose them.  >>



To which Brian Reynolds adds, in digest 3610:

<<...What you describe is a contact printer. ...>>  
(and then goes on to descibe a hand contact printer, suitable for cut films).


A different kind of contact printer comes closer to this.  APAC (American 
Photographic Appliance Corp, the same people who make Kearsarge timers) 
(APAC-Kearsarge. 413 625-2322; fax: 413 625- 2322) make (or have offered in 
the past) automated, motorised roll film contact printers to meet this exact 
need.  They are used by motion picture labs (to make multiple prints for 
distribution) as well as labs like Dale & Seattle Film Works (to make slides 
from negs).  They are/were available in both colour and monochrome versions.  
The exposure is controlled by adjusting both the light intensity & the film 
transport speed.

I've never seen one for sale secondhand, but you could make enquiries with 
some of the "pro lab" organisations (APCL, 
etc)(http://www.pmai.org/sections/apcl.htm).


Hope this helps!

ps.  the advice previously offered on scala & the kodak dp kit seems to me to 
be your best bet...and the comments on processing technique & control are 
spot on.
