1) when you measured tiller, did you use the bow string or a string stretched between the axles? Setting an even tiller with the bow string on a single cam bow will yield a bow that is significantly out of tune.
We might be having one of those north/south language barrier blocks going on here.... As I understand it (and it might be me calling a "Pop" a "Coke", tiller is the distance between the limb pocket and the string. It just makes certain that the bows limbs are let out the same amount when adjusting the poundage. As it was...this bow was cranked down all the way (set at 60.1#s....and it was a 60# bow). The distances I measured were the same....though I don't recall exactly what they were anymore. That is my understanding of tiller. Now, what you have described...I call axel to axel. Probably just a term mix up on my part...but nobody knows everything...my intelligence is certainly not insulted...I'm always up for learning more...thats why I'm here.
2) Did you change the rest to something like a prong rest to see if it would tune with that? I have never used the QAD rest, however I have had a couple of bows that simply did not like a particular rest. They would tune fine with just about anything else.
Actually we did not. I did change the prongs themselves, as the QAD comes with two sets, one is an 1/8" higher than the stock one, to allow for bows that have low nock set or low travel or something to that effect. It didn't make any difference. I honestly thought it was a clearance thing...but I'm still not sure...especially after shooting feathers with it. I did have a QAD that bounced back on my Iron Mace...but that same rest is now on my Mathews LX and it works like a charm. I'm vexed.
