Mortise and tenon wide board
I am in the process of making side tables and have a question about joining the sides and backs with the 4 corner posts. The sides are going to be 12" wide and the the corner posts are 1-1/4" square. I am thinking of using mortise and tenon joinery, but am concerned about wood movement on such large side boards. I am considering using three smaller tenons on each end which should reduce the tension somewhat. If I were to go with three tenons, should I glue all of them?
Any other advice would be greatly appreciated.
