We have all these joints specifically designed to avoid end grain glue joints. I can’t think of how many times I’ve heard that glue joints with end grain are horribly weak and worthless. Almost like there’s not even any point in putting glue there. And when an end grain joint is necessary, you are supposed to add glue blocks that are long grain to long grain to support the joint. I’m trying for the life of me to figure out what this guy is overlooking. Or maybe (as he proposes) the conventional wisdom about glue and end grain is just plain wrong?
