Thank you all for your replies and suggestions.
Gary, I have two external edge coves and two internal as I gave in the dado example. I omitted the external ones in my description. Sorry for the confusion.
Thank you Paul, I like the rasp and fence idea as I don’t have any hollows & rounds. I have followed your rounding over edges with a plane technique on practice wood with success, so using that as a sanding block will work well.
Best to all and thanks again. -Jeff
