BASIC TUNING / TIMING - 101

Always check your bow is free from defects prior to commencing this process. This is what I Do and by no means is the only or the best way to time / begin to tune a bow, but it works for me. No responsibility for any injury or breakages will be accepted by Pats Archery or any of its employee's as a result of following how Pat tunes his bow.

None of this will work if your strings are incorrect in size, worn, or just need replacing. 

I use Scout Bowstrings for my compounds, as we make them here ourselves, I know that they are correct in size and can be relied upon if tough situations.

1.  Check Manufacturers safety recommendations and follow them!! THEY TAKE FIRST PRIORITY
2.  Print information from the relevant bow manufacturers website for A2A and brace height.
3.  Write down your settings prior to starting include
   
   • Axle to Axle (A2A)
   • Brace Height
   • Nocking point height
   • Poundage
   • D Loop Size
   • Any other measurements you may need to get the bow how you like it
4. Wind Bow up to Maximum poundage (This can be done on a HOYT but Mathews do not recommend this so remember to read YOUR bow manual)
5. Check tiller is even, if not adjust tiller to even
6. Is draw length as per the Cam setting ?
7. Check poundage, is it what it should be ?  Yes then goto step if No goto step
8. Was the Draw length too long or too short ?
9. Was the poundage to high or low ?
10. Variables - If the draw length was Correct and the Poundage correct do nothing
11. Variables - If the draw length was too long and the poundage to high - Increase the amount of twists in the string
12. Variables - If the draw length was too short and the poundage to high - decrease the amount of twists in the cables (evenly)
13. Variables - If the draw length was too long and the poundage to low - increase the amount of twist in the cables
14. This hopefully has put the bow back to where it should be when it leaves the shop you bought it from.
15. Now after all that if you need to change the poundage, put a paint pen mark on the adjustment bolt and then move them equally to the desired poundage, be aware that this may change the draw length.
16. This is a work in progress and I type when I have time, so this may not yet be finished.

Other things to consider.

What is your nocking point doing at full draw? Is it moving up or down as you pull harder or does it travel straight. Jim Park mentioned this to me and checking it has certainly helped.
