tuning/tillering question

[howie1968]

i  have  some  questions concering tillering  that concern me   this  is  my  first solo cam bow  it is  a  pse bruin 36  axle to axle 29 inch draw   60 lbs.  i  am  shooting 31 inch  carbon wolverines  with  a  whisker bisquit rest  no  peep but  am  using pin sights  my  questions  are    when  i bottom out  the  limbs  my  top tiller  is  plus 1/4 when  adjusting  to   try  and  get zero tiller or even tiller  one  of  the  limbs  is  backed  out  farther  than  the  other  by  a  good  margine, shooting  fingers  through  a  whisker  busquit  where  do  i  begin  with a  nocling point?  i  started  at  1/8  this  morning  and  was  shooting  ok  i  have  not  paper  tuned  and  to  be  honest  i  do  not  even  have  nock  pliers  right  now  i  think  i  have  gotten  my  bow  so  far  out  of  whack  that  my  nock  point  is  actually  low,  where do  i  go  from here?  do  i  bottom  the  limbs  out  reduce  to  my  draw  weight  then  start  over?  i  dobnt  have  the  benefit  of  a  tuning rack  or  even  bare shafts  at  this  point  i  guess  i  should  have  left  it  alone   but  i  read  an  article  that  said  if  it  aint  broke  fix it anyways

howie1968,

Don't even think about using a ruler or measuring tiller to the bowstring. its not worth doing.

If the bow came through with evenly matched limbs you can get real close to even tiller by just backing both limb bolts ot the same number of turns each.

I reccomend setting an even tiller first, then checking the ATA, BH, verifying the timing, and then setting the nock point above the arrow so that the arrow is 90degrees to the bowsting.

You really have to grouptune at different yardages to set the windage for the rest. Different combinations of draw weight and arrow spine may mean the rest will be left or right of center for the bow to be able to stack arrows on the same vertical line at different distances.

You can leave the arrow nocked at 90degrees to the bowstring.

 If the arrow hits nock high you correct the tiller of the bow by tightening the lower limb bolt till the arrow hits level.

If the arrow hits nock low you correct the tiller by tightening the upper limb bolt till the arrow hits level.


Most bows will shoot a level arrow from the 90degree point on the bowstring if they are set at an even tiller.

Good luck hunting! >>>------------>

Bottom your bow out (i.e. crank it up as much as it can go) and then back out N turns on each limb to get to the desired weight.

If you are doing this and coming out with uneven tiller, then either your limbs are not matched properly or you are not bottoming out your bow completely.  When it is bottomed out, you should not be able to turn the limb bolts at all, as the limbs will be flush against the limb pocket.

Beyond that, it sounds like you have quite a few issues with your bow and do not have the tools to tune it properly.  I'd highly recommend taking it to an archery pro shop to be serviced and watch what they do if you want to learn.

Good luck

Howdy Howie,

 Arrow mentioned a possible "timing" problem..I think you mentioned you had a single cam bow so that Is not a concern as there is only ONE cam. The rest he said is also correct if you can understand it. Dont know how much experiance you have and he is quite technical..Its basicly simple.. If you are having tiller problems and you are SURE you have your limb bolts bottomed out then you need to take it back to where you got it as your limbs were not properly matched. Ive heard of this happening though not often with mass produced bows. TRIPLE check to make sure you are bottoming out the bolts then check to see that bothe limbs are solid against the riser. Now after that is done you will need a straight rule not a tape measure and a short level. First take 2 peices of masking tape about 6 inches long.. Put them on the inside of each limb from the tip down.. Now measure 4 inches from the tip and put a mark..Do this on both sides.. A bow vise would be perfect for this next part but if you dont have access to one the just do your best...Level your bow as close to level as you can..Now take the straight rule and level and put one side of the rule on one of the marks on the tape..Put the level on the rule and level the rule..Now measure to your string...Repeat for the other side..If same the you have no tiller prob..This is the proper method for checking tiller..Now as far as your nock point..Some like to set it to where your nock is 1/8 inch higher than your arrow rest..I, Like arroman, Try to keep mine a centered and level as possible..Some bows will not allow this because of the nock travel cuasing your arrow to either tail up ot tail down..I personally do not use or like the wisker bisquet so I cant really tell you the best alighnment for it as I dont reccomend it to my archery students. Some like them and have goos success with them so they could help you more than I on that...My best advise to you though would be to take it to your local pro shop and have them check the til and tune it up for you..PAPER tuning is a must though in my own opinion..Best tuning tool in the world as it will show you exactly what your arrow is doing as it leaves your bow..Good luck and may the biggun be in that wonderful 20 yard range...Lynn
