That's a great site.
If you want to spread out a little just do a Google using the obvious terms... 'smoking pipe rustication' or 'how to stain a smoking pipe' etc. You'll find all kinds of valuable information here and there. That's how I do it and it always works.
Also, be sure to check out links at the sires you visit. Also, I think there's a list of links on this site somewhere. Do a search on this site and you might be surprised at what you come up with.
Good luck.
