I was reading that page a bit last night. I'm thinking of expanding on the ideas there, making a frame to hold the platic frame level and stead and possibly an electric grill instead of the oven. then there would be no need to move the plastic around.
Raise the frame with platic, turn on electric grill, plastic sags, drop onto mold turn on vacuum and blam hopefully i have a new jp and gauntlets.
Am thinking about attempting possibly a paper mache' JP as my first test subject, we'll see how it goes. Wish I hadn't thrown away my old shop vac now... Gotta wait til payday to start much of this project.
