sure, anywhere from 0 to 3/8” of tiller is going to yield a bow
which aims easily without “pulling” high or low, and which
shoots more quietly. Measure the tiller as shown in the dia-
gram to the right. If you wish to increase tiller without affecting
bow weight, unstring the bow (See page 15) and add turns
to the bottom limb tiller bolt, then subtract the exact same
number of turns from the top limb tiller bolt. After re-locking
the bolts and set screws, restring the bow. Do the opposite
to decrease tiller. You can increase both tiller and bow weight
by adjusting the bottom limb only.
ADJUSTING CENTER SHOT
The final step of tuning is to position your center
shot. To start, position the arrow slightly outside
of the center of the bowstring. To do that, begin
by nocking an arrow and placing it on the arrow
rest. Do not draw the bow, but position yourself
behind the string side of the bow, looking down
the arrow. Align the string down the center of
the limbs and riser and check to see the position
of the arrow tip relative to this line. Adjust the
plunger or arrow rest until the inside edge of the
arrow shaft aligns with this line.
