After two tries, I would move on to someone else. I have had quick replies & service from Norwood on several occasions and there are several others to pick from who can do custom cut stems as well.
You can take a pre-formed stem and re-work it to smoke as well as a custom cut stem, but it won't "LOOK" as nice. If you value your own time, then a custom cut stem is the way to go IMHO because you will be money ahead with a better looking stem.
Now if you want to get real creative, Steve Norse has some cumberland blanks he got in a couple weeks ago. All you need to do is either add a delrin tenon or cut a tenon, fit & sand. They are pre-drilled & shaped @ only $15 each.
