I glue the through tenons. Wood movement affects the tops more than the base, but I leave my mortises just a little over just in case. The walnut beauty stretchers are not glued. If you go to my projects, you will see many slats going one way or another. None of these are glued. Captured in the framework, where would they go? It lets the wood move on its own and hopefully lends a long life to my furniture. I joined Lumberjocks not too long ago and it was a great move to a great woodworking community. I have not set up a blog and don't know if I will, spending too much time online keeps me away from my shop, but send me a message to my homepage for any info or etc.
