I have been a garage tuner for many years and am a fan of the “Winners Choice” products.Â
I recently put on a new string and cable and for the first time (with Winnerâ€™s Choice)Â noticed that my cam timing was not correct.Â
I am shooting a switchback with the cobra cam, using the two small holes to measure timing(make two small holes parallel to string)
My tuning procedures focus on ATA, Idler wheel tilt, cam timing, max poundage.Â If I set these to the recommended specs and set up for center shot (nock 1/16-1.8 high I generally get a good paper tear and broad head flight.
My method of tuning consists of a lot of trial and error. I am looking for some more detail.
I measured my ATA and found it to be 1/8″ too long and my inner alignment hole was tilted up toward the string.Â I adjusted the cable to get proper ATA then I had to adjust string until timing was correct, followed by wheel tilt.Â After setting up the rest for center shot(nock high 1/8â€ťth) I got a great paper tear.
What is the proper order of string / cable adjustment to correct these two problems?
Can I generalize the steps by saying something like adjust the cable to achieve the right ATA and the string to correct the timing, or is it more complicated?Â My question is basically did I do the right adjustments or is there a better method?
Here is how I do it. I always make sure my idler lean is good first. Then I get my cam rotation correct,Â and adjust the ata. Once the rotation is on you can add or take away equal amount of twists in the cable and both string ends to acquire the correct ata without losing your cam rotation.
All three would work. Lets say your ata isÂ on and your rotation is over rotated on your cam.Â You wouldÂ take outÂ oneÂ in theÂ cable andÂ add one toÂ each end of string. That keeps ata the same but adjusts the cam rotation. Or ata is long just add to the string, if ata is short take out ofÂ cable.
