Following on what wvpiper siad, I would suggest also investigating a wood other than ABW (African Blackwood) or rosewood. From what I've read, the use of the darker woods for pipes didn't really take off until the turn of the 20th century.

Perhaps walnut, cherry, or oak? Any good furniture-grade wood would probably work. You'd want something that's relatively stable when cut in short (18 inch) sections. You'd need to discuss with an instrument maker to be sure.
