My daughter has asked me to build a bookcase for her baby's nursery. She saw
something on-line that she likes. It has a curved top. I think I will build
the bookcase out of birch as it will be painted and I am thinking of
laminating 3 1/4" pieces of birch plywood to do the curved top.

Here is my question. I know you have to build the lamination on a form with
a tighter radius than you want to end up with as the wood with spring back a
bit when you remove the clamps after gluing up the lamination. Is there some
guidance people can give me on how to figure out that tighter radius??

TIA.

There are many factors depending on how you go about it, the radius,
the number of laminations, and the wood. As a guideline I'd use 4% of
the radius.
