Many Native American Flute makers use routers or boring equipment and the NAFlutomat software program to determine many design aspects of the flute. They then use wood lathes to produce perfectly round flutes. However, I have chosen to use sculpting gouges to hand carve each half of the flute bore and then glue them together. After hand shaping with a bench sander, the exit and true sound holes are created and finger holes are burned in with steel "burning rods."
There is aso a major diffenrence in the philosophy of flutemaking. A majority of the flutemakers see themselves as making concert quality instruments. Some make them out of multiple types of wood glued together, and almost all of them take great pride in the carving they do for the block, or "bird" that covers the channel between the exit hole and the true sound hole. My flutes, however, are very simple; with no emphasis on carvings or multiple types of wood. In other words, I am not trying to make an art piece, but rather a simple flute. And if requested, I do some inlay work with crushed stone - but only on custom-ordered flutes.
