Spline Roadbed Construction

I onetime used a material called crazy wood to construct a large section of roadbed that had to be self supporting. It was supplied by a member of the club that I belonged to at the time who worked in a furniture shop. It was 5 ply plywood that when cut into cross grain strips 1.5" wide (the wood was 1/4" thick) was extremely flexible and easy to work with. After gluing it into a 60" radius triple track spline of about 300 degrees curvature it was strong enough for some one to stand on and stiff enough radially to stay in shape for the pass 20 years with minimal support. I wish I knew where to get this material because I have lost track of that club member and need to do lots of unsupported track work again and desire to use that material, what ever the cost.
