RE: Porposing? No Resolution?
If you have one in the shop put on a QAD LD(which stands for Lock Down). When the rest is triggered it falls and locks level with the shelf of the bow eliminating bounce back. I have this rest and have not had clearence issues. If bounce back is what your thinking is the problem then i would try that rest. Good Luck with whatever you do.

RE: Porposing? No Resolution?
Tiller is a relative measurement of the preload on the top as compared to the bottom limb. On a true dual cam bow (not a hybrid and not a single cam) the tiller is measured from the limb pocket to the actual bow string, however on a Hybrid or a single cam, there exists the possiblity that the idler and the cam are not the same diameter (like on the Matthews Apex). For those bows, a string is stretched between the axles on the top and bottom cam and tiller is measured from that reference. When you do this, you may notice that the string does not run parallel to the actual bow string.
The axle to axle (ATA) is the measured length between the centerline of the axles. I can't speak for the Fred Bear bows, but on most single cams, the tiller is rarely equal when measured to the bow string. |

RE: Porposing? No Resolution?
Just as a quick check, draw the bow while watching the sights. If it's out of tiller, it'll pull the sights one way or the other. Really, other than just checking to see if it's relatively close to begin with, I don't even bother measuring tiller any more. I simply adjust the limb bolts until I can draw straight back without the bow pulling the sights off target.
If the sights pull up, the top limb bolt needs backed off, or the bottom tightened, or both. If the sights pull down, loosen the bottom limb bolt or tighten the top one, or both. After you've got it pulling straight and even, when you've got the bow's limb tension balanced in other words, readjust the nock point and procede with your usual tuning techniques. |
