Hello, I have only been creating sawdust for about a year so experience wise, lets say I am a beginner. I created a solid wood stove topper for my parents completely out of maple. After gluing up the boards for the top, I then made the box with mitered corners and then cut a rabbet on the inside of the box so the table top could sit flush (wanted to avoided end grain showing). I attached the top to the box with wood glue and some finish nails. At this point, wood movement wasn't something I was accounting for. I was really happy with how it came out but about a year later the seems on the mitered corners started to open. When the stove topper isn't being used, they hang it from a shelf. The did this by screwing a board into a wall and then they just put the stove topper on that board so all of the wait is on one of the sides of the box. I believe the mitered corners came apart because of wood movement and the way they hang the topper. Placing the topper on a self instead of hanging is an easy solution for one of the problems but I'm not sure how to fix the other (attaching the top to the box). I still don't want end grain to show so it has to sit flat inside the box. Any ideas is greatly appreciated.
