I picked up .030" thick clear peta, no not the PETA you are thinking of, a thermoplastic from advanced extrusion to begin testing on achieving a shell of a torso. after a few tests I see my issues are not enough vacuum pressure, (likely need 30-60 inches per mercury), need uniform heat applied to the plastic sheet, and a lower temperature, i.e. a tempurature near tg but not too high to degrade. this i can obtain from the advanced extrusion company, but the other issues likely require access to a vacuum drapeforming machine. For this it seems my only option is to return to Hennepin Technical College and enlist the help of instructor Dan Ralph along with his plastics department. I was able to produce two front shells which are viewable on my facebook page the end results were excellent mixed media pieces I'm really pleased with.
