what affect does changing the tiller on the bow
At the momment my top limb pocket is closer to the string than the bottom.
what is the correct setting

For a compound I use equal tiller (easiest to remember).
For a recurve, the manufacturer will generally have a recommendation. The top tiller should be a little more than the bottom tiller (1/4" typically).

thanks jim i read that in your book but what effect will it have if it is not set to zero

For a compound: changing the tiller simply changes the angle of the riser.
It also changes the cam timing (for a twin cam bow), so once you have the tiller set to what you want, it is then necessary to adjust the cam timing.
The concept of "tiller tuning" was used when steel cables were used. Then you needed to adjust the tiller to adjust the cam timing. Now, with cables we can twist to adjust the timing, it is possible to simply set the tiller to some desired setting, and then adjust the timing independently. Hence, I simply adjust them to both be the same because it is the easiest to remember.

For a recurve, the tiller is there for the purpose of 3 finger hooking, more specifically tailored for the fourth finger (or ring finger). Suppose an archer chooses to shoot with only 2 fingers, then the tiller height is not required.

I think......Actually Mr Kim said so.

recurve: I was under the impression that a positive tiller was the rule on recurves to overcome the below-center pivot point?? However, I know that at least one well known recurve coach advocates zero tiller. I hate being confused:-)

Hmm......Actually I might have quoted inaccurately, but he also did mention the below centre pivot point.

Zero tiller? He must be using FX limbs. heheheheh

Oh, what I think, and I guess some of you guys might have had this same idea, that the objective of the tiller is to do this: Have the arrow travel in a straight line while still nocked on the string. What I gather as a very good, yet unconventional way of verifying this, is to pivot the handle at the grip, put the whole setup on a background with measurement scales, draw the bow mechanically with an arrow nocked in, draw it in a manner that it follow the arrow in a straight line, and observe any change in the angle of the handle. If there is none, then the tiller should be correct and exact.

Then again, it's just my theory. I shall not be held liable for any injuries or embarrassment thus sustained on the shooting line using this method.

I thought Tiller tuning Compounds had the effect of changing the ease of holding on target?
I have been playing with my draw weight and it seems some settings hold real well while others just seem to have me shaking over half the tartget..
