RE: Doin it on my own
One problem with the Arizona EZ fletch is that you have to put glue on all 3 vanes before you close it. By the time you get the proper bead of glue on the 3rd vane the 1st vane may have dried a little if you use a fast drying glue.
The Bitzenburger can be purchased with 1 of 3 clamps, a left helical, a straight and a right helical. If you are only getting one clamp I would suggest the right helical or straight.
Whether you get a Bitzenburger or not I would suggest you get a fletcher that does one fletch at a time. If the arrow shafts are already prepped it only takes a few minutes to do each arrow if you use a fast drying glue. Put the vane/feather in the clamp, run a bead of glue, put it on the shaft, wait 1 minute and remove the clamp and go on to the next fletch.
You really should not be in a hurry when building arrows though. Take your time and craft your ammunition well.
