The Centerboard has been roughed out to its approximate final shape and I have become a tad obsessive compulsive regarding the final shape. The photo shows the NACA 0008 shape as it seemed to fit the final shape of the tip of the foil the best. the NACA 0009 might be better. My plan is to set a dado router bit to the depth indicated by the template and then set a guide for the router to follow. I will set the guides as expanded lines up the foil at several stations as the template can be expanded to fit the width at each point. I used the plotter at http://airfoiltools.com/plotter/index be sure to select "no margins" on the printer or things get compressed. I can generate a NACA foil for several points along the board and then connect the points to expand the lines through the taper. The router would then follow the lines to cut the lines to be planed to.
Area that will be inside the trunk is clearly marked. router will be used to go vertically up and strike marks to plane to.
I have no idea how I will shape the tip, other than just rounding it off.
