could i make a board out of just some very thin balsa and a thin sheet of plastic on top and bottom and epoxy them together. that seems like thats how my hana crew board is made. what would i use for rails i have almost no experience building boards. post pics if you have made one like this.
You have just described the construction method of many top boards !
But,you must be more specific.
Plastic is not just "plastic"
Your materials must be compatable.
