I need some help. I just got mine in yesterday. I got it out and was going to fletch some up. Oh yea I have never done this either. Pretty simple, Right? I'am having problem getting it centered. How do I do thisand what line does the base need to be on, top,middle or bottom? Would someone who has a right hecoil and shoot 2 inch vanes let me know which line you use on the clamp. If i sound like a dum ***** I know I'am . Just trying to learn. Thanks guys.
