This is about finetuning (Cam-Timing)
of 2-cam bows using"Creep-Tuning". Follow our guidelines please.
- As preparation, adjust the cam-timing turning the limb-bolts as exactly as possible. You can give more power to the lower limb - not really necessary (1/8 to 3/16 inch).
- Now, adjust your sight to 20 Yards.
- Mark a horizontal line with adhesive tape on the butt.
- Draw the bow hard into the wall - this is our reference. Shoot 4 or 5 arrows on the line. Let the arrows stick on the line!
- Now it becomes more difficult! Creep a little into the valley before you release the arrow and shoot 4 or 5 arrows on the line. Only "good shots" count. Eliminate bad shots or release mistakes.
- Is the bow adjusted perfectly, all shot are sticking on the line. All is perfect and nothing to change.
- What is to do, if the "Creep-Shots" hit above or underneath the tape?
NOTE: Twinsting in has a more progressive effect than untwisting. In other words, twisting in shortens more than untwisting extends the cable! Hitting above the line:
Shorten the cables connected to the lower cam by twisting in.
Or extend the cable connected to the upper cam by twisting out.Hitting underneath the line:
Shorten the cables connected to the upper cam by twisting in.
Or extend the cables connected to the lower cam by twisting out.- NOTE: Only small steps - half or one full twist. Note down your changes to record the way back. Shoot again 4 or 5 arrows to verify the changings.
- If you need a "Super-Fine-Tuning", repeat the procedure at 45 Yards.
IMPORTANT: Control the cables for correct positioning BEFORE drawing the bow!
