I fletch Blazers on Beman MFX 400's. I had to do some adjusting but after a couple dry runs w/ no glue on the vane I got it pretty good.

One tip that may help....I don't put the base of the vane up tight in the clamp. I let the vane sit about 1/16" from the jig jaws so it will give a little and bend around the shaft when you put pressure on it.
