Update on corner repair. I used a dado blade to make a rabbet around the outside edge of the box to remove the dent. Then inlaid with walnut to match existing inlay. Did this 4 times as there are 4 similar boxes. All is well.
This post is a great example of the strength of Craftisian. After a "situation" (and we all have those project oops that occur), brainstorming on solutions with others is so helpful. I've had so many similar situations (feels like too many!).
