A friend had a different approach to this and we tried it out last night. It really using the basis of a lith article by Ed Buffaloe in blinking eye. http://unblinkingeye.com/Articles/NbyR/nbyr.html
A sheet of paper (MG RC)was exposed in camera for twice the metered exposure (in testing it was found to get the best end result), then under a enlarger set to about 700mm high and lens stopped down to f22 we preflashed the paper for 6-8 sec. Developed , Stop, lights on, Bleach, Wash, Clear, redeveloped in same developer, wash, we then fixed and washed again get to clear the slimy feel. End result is pretty good. That's the basics anyway, we need to do some more testing using some originals which have been exposed the same to determine what different preflash times do to the contrast.
Thanks for sharing the details; I need to try this someday.
