Did anyone catch the episode of "How It's Made" where they went into the Dunhill factory (you don't find out until the end of the segment) and showed how they make their pipes? On my TV it's on one of the SciFi channels (but I can't imagine why) and I happened to DVR it last week. It was pretty interesting. The staining part was really neat, they coat it with an alcohol based stain and basically flash it in place so it dries instantly when the alcohol burns off, then they do another coat, and another, and another. If you haven't seen it, it's worth looking into checking it out.
