I can try to find video - picture shows the basics of the machine... I really want one of these in house. Cool bit of tech, as anyone who has done lay ups knows, getting the material to have the fiber orientation, thickness, and saturation you want can be tricky. The process we utilize the positive plug gets destroyed on every part (rarely they are removed without destruction) Since the internal dimensions mirror loaded soft tissue, the rigid plaster plug usually just gets chiseled out with a pneumatic hammer leaving the laminated bit. We laminate exclusively over PVA bags, which are preformed, we dampen them, stretch them over our models, and let them dry a bit with a heat gun, gets everything to lay smoothly.
