His needs for flatness were not all that demanding so I don't know how flat it was or if it warped at all, but there was no obvious warpage, at least not to the extent that I noticed it. I don't know much about exactly which types of ply, glue, or foam he used so this is probably not super useful info. It was very light and quite sturdy though.
Thanks Pete- good to know if nothing else it’s a durable building method.
