Mine did a similar thing as I would think most
do. I was asking an old, long-time A&P who
still rebuilds and flies J-3's about it (he's also
our EAA tech counselor). He told me to just
wet the longerons down in the jig and let dry.
I used some wet rags to soak the longerons,
placed some aluminum foil over them to retard
drying and kept them that way until the next
evening. I then allowed a couple of days for
them to dry out and it was done.
The boat was then easily removed from or returned
to the jig without any problems. I then skinned it
with the plywood sides in the normal fashion.
