I tested the second method described by
tedsander. Using a brush, I coated the balsa with Titebond and then let it dry. The balsa bowed up but slowly returned to its original form as the glue dried. I was able to iron the two sheets together and the final result was pleasing.
Is it normal for the balsa to become bowed after the glue is applied? I'm worried about it warping down the road.
Thanks,
Josh
