How to Twist a Compound Bow String
- 1). Place the jig on a flat surface in front of you. Position the jig so that the main bar is horizontal on the surface. Loosen the nuts on the post platforms on both ends. Turn the platforms until both platforms are perpendicular to the main bar. Tighten the nuts to hold the platforms in place.
- 2). Cut the old bow string in a damaged area with scissors to release it from the frame.
- 3). Untwist the old string until it is completely straight. Tie one end of the old string onto the bottom right post. This is called the start post. Loop the string around the outside of the other posts in a counterclockwise motion. Attach the free end to the start post.
- 4). Unscrew the bolts that hold the sliding arm of the jig and pull the sliding arm to the left until the old string is taunt on the jig. Tighten the bolt to hold the sliding arm in the new position. Remove the old string.
- 5). Multiply the bow draw weight by 4 and divide the resulting calculation by 10. Divide this calculation by 2. This is the number of loops you should make during string creation.
- 6). Tie one end of a piece of thread to the start post. Wind the thread around the start post until it reaches the top of the post. Loop the thread around the outside of the other posts in a counterclockwise motion until you have made the number of loops calculated. On the final loop, wind the string down the top of the upper right post. This is called the finish post. Cut the thread and secure the free end to the start post.
- 7). Loosen the nuts on the post platforms and turn each platform to the right 90 degrees. Tighten the nuts.
- 8). Measure the loop on the old bow string with the measuring tape. The loop should be measured from the point where it joins the string, around the outside of the loop and back to the point where it joins the string again.
- 9). Measure 1/2 inch from the post on the right. Lay 1 inch of the serving against the thread in that area. Start wrapping the serving around the thread and serving end. Wrap the serving towards the post in a clockwise motion for a length of 1/2 inches. Tie off the serving and measure a distance around the post that is the same length as the loop. Lay 1 inch of the serving against the thread after the loop area measurement. Start wrapping the serving around the thread and serving end in a clockwise motion for a length of 3/4 inches.

Lay 1 inch of the serving against the thread in the 1/2-inch served area. Start wrapping the serving around the thread and serving end of the top to combine the threads on both sides of the post. Wrap the serving in a clockwise motion for a length of 3 3/4 inches. - 11
Cut a piece of thread that is 6 inches long. Loop the thread in half and lay the thread loop against the jigged thread so that the ends are toward the loop. Wrap the serving around the jigged thread and thread piece for 1/4 inch. - 12
Pull 3 inches from the serving spool. Run the end of the serving through the looped thread and pull gently on the looped thread to pull the served edge through the wraps and secure it to the thread on the jig. - 13
Form another loop on the opposite side of the jig. - 14
Remove the bow string from the jig and twist the string 15 times in a counterclockwise direction. String your bow. Measure the drawing surface of your string and locate the center point. This center point is your nock area. Measure 1.5 inches above the nock and 3 inches below the nock. - 15
Lay 1 inch of the serving against the thread. Start wrapping the serving around the thread and serving end starting 1.5 inches above your nock and wrap downwards in a counterclockwise direction for 1/2 inches. - 16
Cut a piece of thread that is 6 inches long. Loop the thread in half and lay the thread loop against the drawing surface so that the ends are 1 inch above the nock point. Continue wrapping the serving around the thread piece and string for an additional 3 inches. - 17
Pull 3 inches from the serving spool. Run the end of the serving through the looped thread. Pull the looped thread to pull the served edge through the wraps and secure it to the string.
