I completely forgot about those two. [Balsa wood and foam-in=place
urethane foam]
I have a good local hobby shop
with large pieces of balsa wood but I suspect it would be more
expensive than good quality expanded polystyrene bead sheet. I will
have to check out foam board next time. Both would be more difficult
to cut without a hot wire knife.
Balsa wood cuts very easily with a sharp knife, glues very well with
carpenters' glue, and will not degrade over time.
