I'm planning on making some boxes for birthday presents in late January.
The profile for the box sides is shown he

My plan is to make a single piece about 48" long for each box, then cut it
into four pieces for the sides. Wood will be walnut, mahogany, or some
other hardwood. What are the options for generating the profile shown in
figure A? The only important dimension is the 4" width, everything else is
approximate. Profile B would be acceptable as long as it can be made
uniform over the 48" length. If someone out there has made a jig or fixture
that will solve this problem and is willing to share the plan, it would be
really appreciated. BTW, I have the usual complement of stationary,
bench, and hand power tools.
