I noticed on Sat evening my bottom limb on my Zipper was twsited badly. Like, the string was tracking 1/2 way between the string groove and the edge of the limb :(
The top limb too was twisted, in the same direction the bottom was, just less severe.
Baffling how, I always use a stringer, I take great care in storing it .... the only thing I hunted THU in heavy rain, and I had limb skin things on my limbs and they got SOAKED - like you could ring a cup of water out of them and when I put the bow up that night, I hung it from a the antlers of a mount and left it a couple of days before shooting it.
Thats when I noticed the twists ---- could leaving those wet skins on there have done it?
Using the hot water method I straighted both limbs, and the string tracks right now, but the lower still has a twist after shooting it some yesterday.
3 days from my big Kansas hunt and I got this ... great :( i did buy a backup Zipper and am having it shipping to where I'll be in KS but I want to know HOW my limbs twisted to begin with you know?
