I don't recall if it was Chad or someone else that was mentioned lite ply in 4X8 sheets. The name given was something I have never heard of before. When I went to my wood supply outlet they haden't heard of it. I was going to bring a piece of lite ply with me to show them but forgot the piece. This is not a hardware store but a high end wood supply. I'm sure I can find something in big sheets that would be the same as lite ply.
Be nice to have a laser cutter but it's a bit much for the home modeler. Lightening holes are a pain to cut .
