RE: Fletching your own arrows
I have a Arizona EZ fletcher too. Fast and accurate fletching tool. It just does not have any adjustment that can be made. For my purposes it workd great.
One bit of advice for you that I have learned the hard way and I now need a new one.
Make sure that you do not use a glue that will run down the vane and get into the pivot point ot the fletching arms. It will glue the arm closed before you know it. Make sure that you use a gel type glue that will stay put when you apply it to the fletching.
Another note: If you use Bohning vanes do not clean them before glueing to the shaft. They have a chemical applied to the base of the vane for better adhesion.
