I use an Arizona ez fletch to fletch my arrows and this past week tried to fletch some with feathers. About 1 in 3 have the same problem: the rear of the feather(nock side)must slide out while compressing the clamp, because it's curved at an angle (the feathers are RW, so they curve to the left, if looking from the rear). Anyway, they look bad. I think they do it because the barbs of the feathers are so short, they don't hold the feather stem in the clamp, and the natural curve of the feather pulls it out. How do I fix it? Thanks.
