It should work bettter as a kerf removes material so that there is less tension on the convex side.

Still cracked. I am going to go with bending birch plywood and epoxy.

I visited Boulter today to buy bending birch as they are near the daughter for whom I am making the book case. I note that the bend puts the finish side on the inside of the curve. I need to have a finish side on both sides of the curved top of the bookcase. Can I bend the bending birch the other way without it cracking? I can of course just try it out but I'd like to get some advance knowledge before I waste some material.
TIA.

Or do as Mr Miller suggested and cover it with Birch veneer. Probably the birch bending plywood is cheaper, but keep the veneer in mind in case the grain is not to your liking.

You can't???!?!?!
Read the directions on the polyurethane glue.
Might be an eye-opener.

I just re-read the directions on the glue. I am using Gorilla Glue by the way. It says dampen one wood surface and apply the glue to the second surface. The moisture activates the glue.

Nope.
Or again you could take Mr Miller's suggestion and use Birch veneer. If you look around you can find it backed with hot-melt glue. Otherwise you can use hide-glue just like they did before vaccuum methods were developed.
Possibly you could use shellac as a hot-melt glue too. I've been meaning to try that.
