When it's hot, or when I'm gluing a complex assembly, yellow glue is hard to use, because it sets up too fast. To slow the drying, I just dampen the wood before I apply the glue. I admit I didn't try this technique until I called a glue company for advice. The company rep said the joints will be plenty strong as long as I don't saturate the wood. A little water goes a long way! Even if the dampened wood appears dry by the time the glue is applied, enough moisture remains to keep the glue moist.
