I posted this in the arrows category a couple months ago.
I find that my DIY vanes stay on better then any that come with the arrows.
My procedure is:
1-remove all previous glue
2-wipe shaft with alcohol (70% alcohol or greater) Don't use the whiskey, that's for drinking!! After cleaning, besure not to touch the area after cleaning, the oils from your skin are enough to affect the bonding. If you want to use a wrap, apply after cleaning shaft.
3-Place your arrow into the fletching jig (Bitzenburger is still the best) and select your vane placement (right, left or straight helical)
4-Determine the distance you want the vane from your nock. Place your vane into the clamp at the desired position. Do not place the bottom of the vane directly against the bottom of the clamp. Leave about a 1/16th of an inch gap from the bottom of the clamp to the bottom of the vane. Some may suggest cleaning the bottom of the vane with alcohol. I would personally recommend not to.
4-Use a good high quality glue. (Fletch-tite platinum, Carbon Express express bond glue, etc.). Place small bead of glue on the bottom of the of the vane.
5-Place the vane clamp into the jig and place the vane against the arrow, starting from the back or nock side of the vane first and working toward the front to ensure good vane to arrow contact.
6- Follow recommended drying time. Some glues will set enough in 1 minute to remove clamp and move to next vane.
7-Adjust arrow for next vane and repeat from step 3 to 7 until complete.
8-After all vanes on arrow, place a drop of glue on the front and back of each vane were it contacts the arrow.
9-Repeat steps to finish your dozen arrows.!!
Also, to make sure the arrows fly well with fixed blade broadheads, make certain both ends of the arrows are square. G5's ASR (arrow squaring device) works great for this.
Good Luck building!!
