Thoughts on cutting foam I agree Andy, I too work for an aviation company and have used a Skandia pin saw for 12 years now. They are awesome tools for cutting profiles in large foam cushions. To build one really wouldn't be that big of a task if you are handy with a welder. They are basically 4 pulleys that have a groove in them for the wire and an electric motor to turn the pulleys. Aside from a framework and table top, that's really all there is to them.
