These instruments are constructed of hardwood. The wood is first cut into 12 angled strips. They are called "staved" because these strips are similar in concept to the staves used to make barrels. The strips are trimmed to a compound miter to create the upper straight bore, and the tapered bell. The pieces are formed into two separate halves, glued and clamped. After the glue sets, the clamps are removed and the halves separated. The inside is sculpted and the halves are glued and clamped back together. Once the glue sets, the outside gets it's final shape and is sanded. The inside and outside are coated with epoxy.
I can attribute their playing ability to the termites in Australia, but the actual construction technique and design I use for them was presented to me in a dream. The bores of all of my hardwood instruments have been "sculpted" based on characteristics of many of the best instruments I have played over the years.
Info on individual instruments coming soon, please call for details.
