Most people I know use the Bitzenberger jig. Either straight or helical clamps can be used, depending upon your preference. It's easy to use, and does a great job. It only applies one fletch at a time, but can be used for either feathers or vanes. It is a little pricey for some folks. For something a little cheaper, try the Arizona E-Z Fletch. It does all three vanes / feathers at the same time.
