I use two Bohning helical jigs and it works great. You'll need a couple of things a vegetable peeler (the best thing in the world for stripping old fletchings and glue off, acetone, green scrubby pad and glue (I use Loctite Super Glue Ultra Control Gel for plain shaft and for my crested shafts I use Gorilla Glue Impact Liquid�don't use the archery glues....they are expensive and inferior in most cases).
First take the nock off and strip off as much old flecthing and glue residue as you can with the peeler. Then place the end of the arrow to be fletched in the acetone can for a few minutes to loosen/remove the remaining residue and wipe with a paper towel. Once shaft is clean, take green scrubby pad and scuff up the area to be fletched for best adhesion, then wipoff off excess dust and dip back into the acetone quickly and wipe excess off with a acetone damped paper towel. Put fletching in the holder and run a very thin bead of the gel down the middle and place on the jig for a couple of minutes, then rotate the arrow and repeat. After all fletchings are in place, set them aside and let them dry. As soon as your done with all the arrows put a small dot of glue on each end of the fletching where it meets the shaft for added protection with pass-thrus. Let the arrows "cure" for 3-4 hours before using.
It also will help stability if you screw the fletching jig down on a small piece of wood like a 6"X12". You can also take a 2"X4" about 18" long and drill a series of holes in it the size of your arrows, so you can put the arrows in there to dry.
