Bingo!!! I talked to the bowshop and got some excellent advice. I did the fishing string method and my tiller has just barely a 1/16" difference. So it's fine... I wasn't measuring accurately at first. My fault....[:-]

Onto the other thing about the vane clearance. You are absolutely correct. I sighted everything all over and even had my wife help me too. The nock point is fine, the centershot is fine too. The bow is properly setup and is fine. BUT... I had the tension on the Quiktune 1000 very light so it was just enough to hold up the arrow. What apparently happens is that, upon release, the Beman ICS Hunter pushes down on the prongs of the Quiktune 1000 which causes the cock vane to make contact. I tightened up the tension so now there is no more clearance problems.

Live and learn.... [:-][&o]
