Gray Beard,

I have been reading the expression "light ply" for a long time.
I am still wondering what people consider "light ply".

My understandng is that "light ply" is laminated balsa of some degree of hardness (weight per volume) and my understanding of "hard ply is plywood made of bass, pine, spruce or birch.

Am I correct ?

Thanks for your knowledge on this subject.
