1 PAGE nary Bow Setup .. 14 MAINTENANCE AND ASSEMBLY .. 15 AACC.. 272 Arrow Tuning and Maintenance GuideINTRODUCTIONS uccessful tuning can only be achieved by using a prop-erly spined arrow shaft. Start with a shaft recommendedon easton s Arrow Shaft selection chart , available on theEaston web site at , in the EastonTarget and Bowhunting catalogs, and on the easton ShaftSelector Plus software program. Final verification isachieved during the tuning process. Problems caused byan improperly spined shaft will become evident duringtuning.

2 Before tuning, be sure that shafts are straight,properly fletched, and have perfectly aligned Your Shooting procedures for the three most popular shootingsetups are described and abbreviated throughout thisguide as follows:urecurve bows, using finger release (RF)ucompound bows, using finger release (CF)ucompound bows, using a release aid (CR)Some of the techniques of bow tuning apply to all types ofbow setups and others apply to just one or two separate tuning procedures are required for specificsetups, find your setup within the topic and follow thosespecialized All AccessoriesBefore starting any bow tuning, be sure to install on yourbow all the items you intend to use when shooting.

3 Thisincludes the correct bowstring, bow sight, stabilizers,arrow rest, cushion plunger, bow quiver, etc. Any adjust-ments made to the bow or changes in bow components canaffect the tune of your equipment. Remember, when tuning,it is very important to change only one variable at a time!The first phase in achieving well tuned equipment is goodpreliminary equipment setup. If the initial setup is donecorrectly, bow tuning can be an easy process. By followingthe bow setup guidelines in the initial preparation of yourequipment, you can eliminate most or all of the possibledisturbances that cause tuning problems, including falsetuning indicators.

4 An example of a false tuning indicatorwould be having a high nocking point indication when theproblem is actually poor the Nocking PointInstall a moveable nocking point on the bowstring. Clamp-on types are ideal. Initially, position the nocking point onthe bowstring about 1/2" ( cm) above square for RF andCF and approximately 1/4" above square ( cm) for Fig. limbBow limbTapeTapeWheelWheelBalancedlimb center(left mark)Measured 3/16"from actualcenterActuallimb center(right mark)Compound BowBalanced LimbCenter the Limb CentersIn order to have a reference point from which to adjust thearrow's left/right position on the bow, it is necessary to findand mark the exact center of the limbs on a recurve bow,or what is termed the balanced limb center on a com-pound bow, as defined BowsTo find the limb center for recurve bows, place apiece of masking tape across the inside of each limbnear the riser.

5 Measure the width of the limbs, andmake a small vertical mark on the tape in the exactcenter of each BowsTo find the balanced limb center location for thepreliminary setup of your compound bow, place apiece of masking tape across the inside of each limbnear the riser. Measure the width of the limbs, andmake a small vertical mark on the tape in the exact centerof each limb. Next, measure 3/16" ( mm) to the left of themark (for right-handed archers) and make a larger verticalmark on the tape. (Left-handed archers place a larger mark3/16" ( mm) to the right of the limb center mark.)

6 Thissecond mark will be used for arrow centering. (See Fig. 2.)This procedure is done to compensate for the amount theeccentric wheel or cam is offset from the actual center ofthe limb. The 3/16" ( mm) measurement is an average offset difference for most compound bows and does notneed to be a precise measurement in the preliminary setupstage, as you will locate the true balanced limb centerwhen performing the fine-tuning procedures. Centering the ArrowThe objective of arrow centering is to have the arrow leavethe theoretical or balanced limb center of the bow.

7 Inactuality, it is the two nodes (Fig. 3) of the arrow shaft thatshould leave the center of the bow in direct alignment tothe target. Releasing the string with fingers creates ahorizontal bending motion within the arrow. Releasingthe string with a release aid causes a slight up/downbending motion. Because of this, the arrows must bepositioned differently for each style of release. Adjust thehorizontal (in/out) position of the cushion plunger orarrow rest assembly so that the tip (center) of the arrowpoint is correctly aligned with the type of equipment youshoot.

Thearrow tip is placed slightly outside the string to providecompensation for the amount the cushion plunger or sideloading device compresses into the bow when the arrow isreleased.

9 See Fig. a finger release, the arrow bends horizontally, firstbending in toward the bow, then bending away from thebow, which causes the arrow shaft to leave the arrow the next bending sequence, the arrow nock disengagesfrom the bowstring. The arrow is then on its way, freelyoscillating all the way to the target. The amount of oscillationdecreases as the arrow travels farther from the Release (CR)Align the tip of the arrow point down thecenter of the bowstring. See Fig. 5. The centerline (axis) of the arrow must start out in a directline with the bowstring when the bowstring is aligned tothe balanced limb center.

10 See Fig. using a release, the arrow most often bends vertically,rather than horizontally. Therefore, there is no need for aninward compression device such as a cushion the bow tuning methods in the Fine Tuning andMicro Tuning sections on pages 12-14 to find the bestin/out position for your arrow shaft, which allows thearrow nodes to be in direct alignment to the diagrams in Fig. 7 indicate the correct in/out arrowposition for your shooting Bow SetupArrowTip Out1/16"-1/8"ArrowTip inlinewithbowstringRecurve BowFinger ReleaseCompound BowFinger ReleaseCompoundBowMechanicalRelease AidBowstringalignedwith limb centerBowstring aligned withbalanced limb centerArrow Nodes - As the arrow oscillates, the nodesremain in direct alignment to the target.
