I am looking for opinions on how to attach the finished top of my Kreg bookshelf to the rest of the bookshelf. The best i can think of right now is to glue and brad nail from the underside inside the shelf. I just don't think this will be sturdy enough. The first thing people grab when they go to move furniture is the top. To me this joint should be able to support the full weight of the shelf and I don't see brads and glue doing the job. Any suggestions would be great?
