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??

The other option is to take your best guess on the radius, create the bent
laminated parts and then, if your resulting dimensions are off a bit, adjust
the dimensions of the rest of the bookcase to work with the laminated
pieces.
