TUNING & QUIETING YOUR BOW


Send your detailed tips and we will post them WebConnections

Limb Alignment

Problem: Bow string does not stay in limb groove.

Diagnosis: Limb Alignment - important for center shot.

Solution: 
1. Loosen saddle screw(1/8")at butt of outboard limb 3 turns.
2. Place bow flat on table, string facing upward.
3. Grasp limb at tip & twist in direction needed while holding down bow at the hinge area. It is best to over compensate at this point. The string should have the effect of laying on the opposite side of the string groove.
4. Tighten saddle screw.
5. Draw bow.
6. Check alignment.
7. Repeat procedure if necessary. What we are trying to do is shift the yoke cable through the saddle. The yoke cable holds the left/right alignment of your limb and has a memory that needs resetting. If limb still looks twisted after a few attempts:
8. Change the yoke cable. The cable is color coded on the tips of the swedges tucked in the cam. Be sure to locate the
proper color codes on each end of the cable. If you are unsure of the cable size, we can help you by knowing the bow
serial number or draw length and model.

NOTE: This process can be done without a bow press and
without relaxing the poundage weight.

Stealth model: Loosen the two saddle screws on outboard and
follow same procedure.


QUIETING YOUR ONEIDA EAGLE BOW

Check the obvious.

Check for:
Brace Height Too Low : Raise the brace height to be in your bow model specs by twisting the string to bring brace height up to specs.
Loose Accessories : Such as sights pins, pin guard, arrow rest, quiver, etc.
Timing : Loose timing system.
Hinge : Check and oil hinges.
Check : Saddle screws and hinge screws and tighten ( loose screws will cause clicking sound )


OTHER TIPS
Install Silencers :
Install puff silencers on string tight against outboard limb.
Add : Mole skin or fleece on outboard limb where string makes contact to dampen string noise.
String : The use of B-50 Dacron string will quiet your bow tremendously. This string material has elasticity and is forgiving, however it will slow bow speed 12 - 15 fps. When going from a omni flight material to B-50 make the string length 3/4" shorter to allow for the stretch that the B-50 has.

I found that when setting up an Oneida bow with a peep in the string, I like to use the true peep from Fletcher Products. What I do first is take the string off and rotate it the same way it rolls when pulling it back. This is the opposite of when the bow arrives in the box. If you rotate the string until it flattens out or straight, Keeping track how many rotations you have made, keep rotating the string the same amount of rotations it took to flatten the string. What this does is less rotation in pulling the string back and still retaining brace height. You might have to go an extra turn or two, and that is o.k. as long as it  is in the recommended brace height.
Contact me if you have any questions.

TUNING THE STEALTH

Stealth_1.jpg (38108 bytes) To time this bow you must understand it was developed to work as close to a regular wheel bow so that no extra timing procedure was needed unlike all Oneida’s with the slotted adjustable system. Most thought they could just reset at any point with weight on and the bow would be in time top and bottom. Disaster was the result in most cases. The thing to realize is that timing or synchronizing must have a starting point or a relationship to the straight line of the bow. If you draw a center line through the side of a stealth riser and in reality it already has one (the timing channel) we can use this to determine cam rotation and synchronizing of movement.

There are three points (Fig. 1) we can use at each have exactly the same relation to the center line of the bow: 
1. The axle on which the cam is placed.
2. The idler wheel.
3. The slot holes that are cut into the cam.
Stealth2.jpg (31438 bytes) Method of Timing

If your bow has limbs on the best way to start the first time is to take them off;
1. Back off limb bolts until string is limp and cables are loose.
2. Take off string by pushing on outboards.
3. Take all cables out of cam slots.
4. Remove limb bolts and limb assembly.

Now that you have the riser with just the cams, loosen the timing hub set screw and it should relieve tension on timing cable.

Note: On right hand bows timing hub is located on top cam assembly and on the bottom of left hand bow.

Note: You need to acquire from Oneida or Bowtech Unlimited two custom made pins to use for cam timing location. These pins are a specific diameter that will set cams at exactly the position in relation to the riser center line for my specifications for the bow.

Place each of these pins (fig.2) into the cam location holes at both ends of the bow and rotate cams to the rest position as they would sit if the bow was completely assembled. The pins will go all the way through both right and left cams at the same point and will touch on the idler wheel and the timing wheel cable as shown in (fig.3).
Stealth_3.jpg (32013 bytes)
Once you have pins and cams located in rest position you can hold them in place and have someone else retighten the timing cable take-up spool or use two elastic bands to hold pins against idler wheel and timing wheels at either ends of the bow. When you have done this correctly there should only be 1/8 of deflection on the timing cable at either end and cams should be an equal distance from the centerline of the bow at any point in there rotation.

Key Points: 

1. Timing cable should be tight with 1/8 deflection at idler wheels.
2. Pins have to be at equal points through RT. and LT. Cams.
3. Check relation to center line of bow.

After timing procedure is complete reassemble the bow. DO NOT loosen the timing system again; it should stay perfectly in time without retiming at weight adjustments as long as you follow these rules:
1. During assembly keep weight bolts at same increments from riser.

2. Only two full turns on each weight bolt at a time alternating between the two.

3. Most limbs were not a matched set so tiller should be close but can differ but should be within 3/16. Note: C.P. Oneida now match sets all limbs.

4. Bow is set up properly when equal amounts of deflection are measured at both ends of timing cable (1/8). If one end is tight and the other is loose then it is not set up properly. To adjust the rule is tighten weight bolt a 1/4 of a turn at the same end the timing cable is tight and this should relieve and equalize the tension. This also increases final weight by a bit. If you adjust at weight bolt that is at the same end as the loose end of timing cable you must back out limb bolt and this will decrease the bow weight. 

With practice you will be able to set up and maintain a Stealth Eagle’s timing system in minutes and be confident of the stability and performance of this bow.

THE CATFISH LOOP
By Tom Johnson ( AKA CATFISH )

#1 - Put two small finishing nails in a board about one and three-quarters of an inch apart.
Wrap the Loop string (like BCY's #62 Braid) around the nails four times.  Tie a square knot and leave one tag end one inch long and the other eighteen inches long.


Untitled-2.jpg (30328 bytes) #2 - Slip the coiled loop off the nails and place the coil under the bowstring in the area  you intend to place the loop.

Untitled-3.jpg (29505 bytes) #3 - Take the top and bottom of the coiled loop - the four strands above and the four strands below the bowstring - and pull them towards you over the bowstring.  At this point you could lift up on the bowstring with the eight strands of the loop.

Untitled-4.jpg (29498 bytes) #4 - Begin wrapping the eight strands of the loop with the eighteen-inch tag end, and wrap over the one-inch tag which lays along the loop.  The knot in the original coil should be next to the bowstring on the shooter side.  Wrap the first time between the knot and bowstring, and continue to wrap tightly over the knot and around the loop. At no time should any of the Loop wrapping go over the bowstring itself.

Untitled-5.jpg (30224 bytes) #5 - When you have wrapped about three-quarters of the way around the loop, take a waxed piece of string (dentil floss will do) about twelve inches long, fold it in half, and place the loop of the floss over the remaining strands of the Catfish Loop with part of the floss loop protruding past the bowstring.

Untitled-6.jpg (27726 bytes) #6 - Continue wrapping over the Catfish Loop and the floss until you have wrapped snugly up to the bowstring.   Holding the wrapping snugly, take the end of the string you have been wrapping with (the eighteen-inch tag end), and run it through the loop of the floss.  Leaving a bit of slack in the tag end that runs through the floss loop, grab the other end of the floss (sticking up through the Catfish Loop near the center) and pull the tag end through (under the ten or so wraps of the Catfish Loop).
Be careful not to run this last wrap over the bowstring - only the Loop.

Untitled-72.jpg (28059 bytes) #7 - You should now have a served loop on the bowstring with a small tag end (the one you pulled through) sticking up through the loop serving.  Cut this tag end off as close to the Loop as possible.

Untitled-8-2.jpg (29064 bytes) #8 - Voila!!  You now have a Catfish Loop on your bowstring!  It should turn, with some pressure, on the bowstring.  All you need to do now is crimp or tie two nocking points inside the loop and adjust them up or down to fine tune your bow.  To adjust the size of the loop you will need to change the spacing of the nails in step #1.

Some folks put the nocking points outside the string-loop instead of inside. I like them inside because it makes a wider loop for attaching the release. Here’s an example of using string nocking points on the outside:

http://www.thebowman.com/tbropenock.html

Like everything else, it’s most complicated when you first do it, then it’s amazingly easy. It’s also good to know because in emergencies you can make a nocking point in the field.

Brass nocking points are really quite heavy, and can slow arrow flight. String nocking points weigh almost nothing, and work really well.

 80% Let-Off Bows

    In 1993 Oneida Eagle was the first to introduce 80% Let-Off in the X-80 series of bows. The Oneida 80% Let-Off is the only True 80% meaning that the let-off is 80% meaning that the let-off is consistently 80% at all points not just at the anchor as with many bows. The 80% Let-Off, in combination with the Oneida PDC (perfect draw control), gives a smooth draw with a gradual valley making it remarkable bow to draw. The response to the introduction was tremendous and continues today in the Oneida bow series.

    The 80% Let-Off feature on an Oneida bow will enable the shooter to draw about 10# heavier in bow weight than a standard compound. The Oneida design incorporates a very smooth draw curve which lets off early and gradual, making the bow shooter friendly.

I.        BENEFITS
          A. Allows archer to maintain full draw longer
          B. Allows archer to hold more poundage and hold less
          C. Archer can maintain a comfortable anchor point
          EXAMPLE: Draw 70# peak-holding 14# 

II.       YOUNG ARCHERS
           A. Easier for youth to draw
           A. Eliminates stress fatigue after shooting

III.      KEEPS PEOPLE SHOOTING
           A. After injuries: shoulder, neck
           B. After heart attacks, arthritis
           C. Smooth draw enables them to continue shooting
           D. And amputees using thier mouths to pull string, only Oneida enables this.
