In Response To: Hollow shaft (Nick Schade - Guillemot Kayaks)

Do you think making a square hollow and coring it with polystyrene foam would be a viable option? Would the foam provide enough structural support to prevent failure in a diagonally (diagonal to the 4 sides of the "box" shaft) loaded situation?

Just trying to figure out an option besides buying a router!
