Thanks. Good observation, and question. I'll have more to say on this in an upcoming post. The general plan is to only glue the bottom tenon on these panels. That's because I need the bottom to remain fixed so shrinkage does not separate it from the trim around the base. The top third of the panel will only be attached via the pins. These will be inserted into elongated holes to allow some movement.Question, on that wide panel will you glue all three tenons or just one to allow for movement?
