I use to have a homemade feather burner. It tended to char the edges of the feathers, that brittle edge always made noise. I had some four inch four fletch arrows make noise this year, with those , it was the blunt lead edge of the quill. A bit of shaping with a diamond fingernail file and a drop of glue worked. I use to also have a feather book and sanded my quills to a minimum, I have gotten lazier about feathers, but that old stuff worked. "Arrows whislte in flight, afternoon delight" sorry, I will get back to work now.
