If you have a fairly good band saw, this is a simple thing to do with a circle cutting jig. You can cut the circle on the table saw, but not the concave curve for the straight boards.
Google or search circle jig for bandsaw and you will see how simple it is. Joning the boards is no big deal, you would break the wood before you break the glue line with modern glues.
