I've been playing with using a release to give my arthritis a break. In setting up the bow, I'm using Discovery R1 mediums on a 19" Atlas riser. I initially set the nock points at about 3/8" high. I left the tiller bolts alone. The D loop is tied on the outside of the nock points. After getting used to the release, I started attempting to shoot for accuracy. The arrows were impacting about ten inches high and to the right. I'm not worried about the windage just yet so I decided to play with the tiller to pull the impacts down. I decided to try negative tiller first and turned out the bottom tiller bolt two turns more than the top bolt setting. That actually pulled the impact down to where I wanted it, but the bow wasn't happy at all. I reset the tiller to neutral, shot a few arrows, and the arrows were back to impacting quite high. The bow was still noisy so I bumped the brace height up to 8 3/4". That helped with the noise level and the impact came down a couple of inches. Now I have a bounce off the shelf, so the impact point doesn't really mean anything. I moved the nock point up some more, but I'm about a hundred arrows in for the day and the temperature is in the mid nineties, so I haven't shot that setting yet.
All the while I'm playing with this I'm thinking about the old Bear bows from the mid fifties that had so much positive tiller that the bow looks like the top limb is about to give up the ghost. I never quite wrapped my head around why they did that. I'm trying to think through what putting a D loop on the bow does to the impact in relation to how arrows impact using three under or split finger. If I'm thinking correctly, a D loop would be similar to two finger split, which should bring the impact up a bit. So I'll finally get to my question: if I weaken one end of the bow, does the impact move away from the weaker limb or move with the weaker limb?
