Have been practicing angled dovetails recently. But only single angled. That is, two boards are vertical, 2 slanted. Interested in making a doughbox or sea chest with sides and ends angled outwards. I watched Chad Stanton do it on youtube. He cuts the boards on a tablesaw. I read that Roy Underhill describes the technique of compound dovetails in one of his books. If so, I would buy the book. Wondering if anyone can comment on a good reference for this or their personal experience.
