I called and asked what glue would work best on bare aluminum. I got two tubes. I cleaned them with acitone until they squeaked. Made a six batch of four fletch four inch and put on herters four blade heads for turkey hunting. I went down to a place where i had seen strutting years before, nothing. coming back up the hill i noticed that someone had the same feathers as me and lost one. It looked almost new so i put it in my pocket. LaterI was sitting in a cedar cluster, looked at the ground and dang that guy who was losing feathers was here there were two more feathers on the ground. Finally, the bell went off. I could have gotten a littering ticket, so many feathers I was missing. I use the tape, I put on three dabs of super glue, front, back and middle, I push the quill to seat the feather tight, and have not had a feather come lose since. If your aluminum shafts are clean they stay, if you use three dabs of glue they do not come loose or get soft and move on a hot day. The tape works.
