Fine Tuning of 2 Cam Rollover (Wheel Timing) by "Creep Tuning"

1. Set the Timing as close as you can by eye with the limb tiller already set ( I like one eighth to three sixteenths of an inch shorter measurement to the string on the bottom limb but it is not critical).

2. Sight in at 20 yards.

3. Put a horizontal line on your target butt. (masking tape is good or use the top edge of a target face.)

4. Pull your bow into the "wall" (or stops) as hard as you can and shoot a couple of arrows at the line. Then "creep" forward to the front of the "valley" and shoot a couple of arrows. In all cases you only use your good shots so you may have to shoot more arrows to get some good ones.

5. If your bow is in perfect time all your good shots will hit the line , if not here is how to tune it. If the "creep" shot hits high, tighten or shorten the cable or cables that connects to the bottom cam.

If the "creep" shot hits low, tighten or shorten the cable or cables that connects to the top cam.

Those of you with the " Wedel Cam" and "Quadra Cables" can do this without a bow press by pulling one cable towards the limb enough to allow removal of the other one on the same axle to adjust. You must of course be sure all cables are mounted on the axles properly before pulling the bow but this allows "Creep Tuning" your bow very quickly at the practice range.

Make small adjustments and test to see that you are improving the tune and when you are done at 20 yards you can follow the same procedure at 40 yards to "Super Fine Tune" your bow.

When you have completed this procedure your bow will be Timed to perfection and if all your other accessories are adjusted properly , your bow will be as accurate and forgiving as possible.

I hope this will add to your scores and would like input as to your results .
