I am wanting to make a board in the 8 1/2-9’range. My thought is to use extruded foam in strips with stringers between through the width,like every 2-3 inches. I am looking for a idea of what the weight should be? So I can figure how the stringers can be placed. Also does anyone know the est. weight of the glass? The idea is to strengthen against shear and control gassing effects. Also I think it will look good.
I am not sure what kind of measurements should be used.length,width,thickness?
thanks
