How to Install a String Leech

A string leech is a small piece of rubber that attaches to the bow string. The rubber absorbs the shock of the string and silences the sound created by the vibrations. Installing a string leech requires two small sections of string that serve to hold the leech on the string. The installation process is easy and the bow does not require pressing. The string leech is a valuable hunting tool and prevents game from hearing the shot before the arrow reaches the impact point.

Instructions

    • 1

      Measure the distance between the nocking loop and the axle on the bowstring. Measure the top portion of the string and bottom portion of the string. Divide each measurement in half to determine the installation point for the leeches.

      Use a string separator to split the top section of the bowstring in half. Place one leech between the sections and remove the separator. Adjust the position of the leech until it is on the measured point. Also adjust the position until the string sits on the groove on each side of the leech.

      Cut 2 feet of nylon serving thread. Loop the thread around the string above the leech. Tie an overhand knot to connect the thread to the string. Tie a second overhand knot on the opposite side of the thread. Continue tying alternating knots until you have 10 total knots.

      Complete the string of knots with a double overhand knot. Add a small drop of instant glue to the final knot. Use a paper towel to prevent the glue from spilling on the bowstring. Trim the excess serving thread with scissors.

      Add an addition section of serving below the leech to secure the leech on the string. Install the second leech on the bottom half of the bowstring with the same process.
