I'm building a fin set for my Saturn IB rocket that goes from quite thick to a knife edge. I plan on using a birch plywood core, with balsa on either side sanded to shape, and finally covered with a layer of carbon fiber. It is a high power model, but I have quite a large margin for fin flutter, so that's really not a concern.
So my question is this. Is there any advantage to using epoxy over wood glue for attaching the balsa to the plywood core? Wouldn't the wood glue be lighter (a concern) and adequate to the task? The outer carbon fiber layer would of course be using epoxy.
