Adil,

Try these steps...

1. Make sure you have proper arrow to bow match.
2. Make sure your brace height is within the acceptable range for your
bow's length.
3. Make sure you button tension is at medium for starting out.
4. Make sure that the center of the arrow is touching the center of
the button. If the arrow sits too high or too low, it will cause the
plunger head to wear unevenly. Which effects the horizontal
positioning of the arrow. This adjustment is normally made by
adjusting the arrow rest's vertical position. Some bows allow for
vertical plunger movement, but I would rather you set it at center,
then adjust the arrow rest.
5. Make sure that the horizontal position of the button is correct,
and that your arrow rest arm does not extent past the outside diameter
of your arrows.
6. Make sure your nock height is within the acceptable initial range.
7. Test for best nock/vane position. Shooting a group of three arrows,
make a slight adjustment in vane positioning (the same for all three
arrows) and powder test the vanes for clearance problems.

Here's a lengthy way to determine your nock/vane positioning. If you
are pretty consistent, then try this from 30m:

A. Measure and mark the nock/vane position, then write the nock/vane
position on a paper plate, then shoot one group of three powder tested
arrows, all with the same nock/vane position.
B. Note on the paper plate if you observed any clearance problems with
the powder test. Then set aside the paper plate.
C. Start a new paper plate, rotate the nock/vane position about 3mm on
all three arrows. Mark the paper plate with the new nock/vane position.
D. Shoot again, one end of the three arrows. Write the powder test
results on the paper plate.
E. Follow the above steps, rotating the nock/vane position 3mm at a
time until you have covered essentially 1/3 of the arrow's circumference.
F. Once complete line up all of the paper plates. Remove all the
plates that you have marked with negative results for the powder test.
G. Evaluate the remaining plates. Find the one with the best group,
that's the nock/vane position that I would set all of my arrows to.

You can get by with just a few powder tests, but the above method will
help to reduce even the slightest contact, by defining the best
nock/vane position.

I think if you follow all of the above you will correct any clearance
problems you might be experiencing. If you are still having problems,
then I would say it is more an issue of the "user," than it is the
equipment.

Let me know how that helps you… Also, refer to the Easton tuning guide
which is available online and in our files section of our group website.

Hope that helps,

-Daniel Perez
