In the past I have glued and pinned (micro-pin nailer) molding pieces to a cherry or oak veneered plywood case.  I did this for pieces I have made for my family and friends. It seems to have held well in those situations (my personal pieces are still doing well after 7 -10 years and no one else has called to complain). But now I am retired and preparing to do some small custom work for customers and I worry about the relationship of the stable case to the expanding and contracting (albeit hopefully only to a small degree) solid wood molding (usually less than 3″ in width). My thought is, that to be safer, perhaps I should just glue a narrow center line down the length of the molding and pin it rather than gluing up the entire width of the molding along its length inorder to allow for the minor expansion and contraction. Am I overworrying this just because I want to be paid for something rather than giving it away for free? Expert advice is welcome!
