Milling the "Beadboard" for the Hatch

The inside of the hatch will be exposed - that is, the ribs will be covered on the outside but not the inside, leaving the ribs visible.  The outer covering will consist of 3/8" thick by about 3/4" wide tongue-and-groove boards with quarter round noses.  Originally it was to be traditional beadboard, but since the board width needed to be narrow in order to conform to the curve of the hatch, the additional grove was eliminated.  On top of the beadboard we will add a layer of 1/8" Baltic Birch plywood.

We started with 8/4 white oak nominally dressed to 1-13/16".

From this we sliced 3/8" pieces that were subsequently ripped in half.  The first milling step was to create the groove and nose on that side, followed by milling the tongue side.

Here is the setup on the router table creating the tongue side:
