Adjusting Peep Rotation
By Mike (Javi…) Cooper
When installing a new string, I recommend shooting approximately 100 shots through the bow before installing the peep.
After installing the peep, make a note of which way the peep is facing, you will use this as your guide. Nock an arrow, point it safely at the target butt and shoot; notice that the peep has rotated from its earlier position.
The string will creep and settle for the first few shots. Once the string has settled, you’ll notice the peep will be in exactly the same position after the shot.
It could take as little as twenty shots or as many as a few hundred, depending on the quality of the manufacturing processes and the material used in making the string.
Once the string has settled you can tune the peep, make sure that it is set to the correct height and begin by nocking an arrow and drawing the bow slowly, watch how the peep moves as the string goes through the draw cycle. This is will tell you what to do with the peep.
If your peep rotates from left to right, press the bow and twist the string a ½ twist in the same direction. I recommend that you twist from the bottom cam end. Now shoot the bow several times to settle the peep. If it still does not roll into the proper position, repeat the process. Always shoot the bow several times to settle the peep before checking for position. If the peep settles exactly opposite, then just flip the peep to face you.
Relax the string in the press only enough to be able to get the peep out and turn it a half turn. Remember that each time the bow is in the press you must shoot the bow several times to settle the string. Occasionally the peep will settle just a little off no matter what you do. At this point any adjustment moves the peep too far; it is the time to flip strands.
Relax the string again. Look carefully at the direction of the string twist. For example, if the normal twist of the string is clockwise, and your peep must move to the left a ¼ of a turn, take two strands from the top left side and flip them to the bottom right side. Then take two strands (make
sure they aren’t the same two strands) from the bottom right side and flip them to the top left side. This will pull the peep over to the direction you want.
If you want to move it the other way, just do the same steps in the opposite direction. Note: more strands will mean more movement.
Shoot the bow to re-settle the string and repeat as necessary…
If you have the patience this will work…
Something to help you when you install a peep sight that has no rubber tubing attached to it. Good luck.
