Anyway, I have been using Dar's dies and some of Lee's rubber with good results on my experiments.  My background is comercial metal work using punch presses etc. I have been examining all available literature I can get my hands on and still believe that the best source is Susan's book and the stuff you guys share with us.

I have run accross a 1990 or so Boeing Engineer training manual (16 pages) that has some interesting "hydroforming" techniques using a press with a trapped rubber blanket. (about 2 pages with drawings)  The metal being formed is cut to size and placed on a fixture / form?.  The press / blanket forces the metal down over the fixture. There is a note about flange length development and under cutting the fixture to allow for metal spring back.  If there is interest, I will send Lee a copy and he can translate the jargon into artist speak.  --- SAN
