We suggest squeezing the arms in the center which will insure even alignment of the fletching arms along the arrow shaft. At this point before replacing the top cap, check the feather at the top of the arm to make sure they are still in place. Sometimes the very end of the feather rolls out of the slot. Glue set time will vary because of climate conditions and also the amount of glue used. You can do a few test runs to establish the set time needed for your arrows.
Feathers require substantially more set time than plastic vanes.
This is the secret to making a 4 fletched arrow. Before starting the fletching process, please insert an arrow shaft with a glued nock into the E-Z Fletch. Make sure it is seated firmly down and on the nock receiver. Now gently rotate the arrow counter clockwise. Count the clicks and you will find there are 16.
