Wood Laminations and Springback

I'm working on the center section for a Hatz. The trailing edge of the
center section is a recurved lamination that provides better access to the
front cockpit.

I've steamed and clamped the strips into a form, and they have taken on some
of the curve, but when I unclamp 'em after they dry, I get significant
springback. The question is whether I need to allow for this in the
finished lamination, or whether the springback will go away when I glue up
the assembly?

FYI, the lamination starts as four 3" x 1/4" strips.

Thanks in advance,

Kyle Boatright

Never mind.

This was supposed to go to R.A. Homebuilt...

Just did my first laminations a few months ago. They didn't spring at
all once they were glued up.

Just curious, to see how your experience stacks up with laminations I have
done.

What was the minimum radius for your laminations, approximately?
