I use it occassionally but have never had fletchings come off.Before I take the backing strip off,I' ll run my finger along the base of the quill(while in the clamp) to make sure I have contact the whole length of the feather.After I fletch,then I' ll run my finger over the feather with pressure to make sure I have good contact on the shaft.Then I' ll put a drop of super glue on each end of the fletch.
