    Eh

    Not to sound like a know-it-all but I'm pretty sure that won't work. Here is the reason. A head bolt is torqued to a certain value. That value stretches the bolt and retains the "grip" on the threads which is why it doesn't back out. Don't torque it enough and it will back out. If I ran full poundage on my bow it very well could work. But once I back it off a turn or two the stretch is gone and I don't "think" it would make any difference from what I have now.

    What gets me is I am the only one with this situation and I don't understand why?

    Would be worth a try, that or Nylon Tipped Socket Set Screws. My old PSE Mojo had them and man was it needed, the worst hand shocking vibration making bow ever made!

    But I don't shoot maxed out so it is really not a good solution. Just as the set screws are a band-aid fix. I want to know why I am the only one of the hundreds on this forum that is experiencing this oddity?

    More likely just a manufacturing issue, like my shadowcat limbs.

    Just a suggestion, but check cam timing. If they aren't perfectly synced it causes extra vibration.

    I'm no expert but I think the timing is as good as it can be. I have it set that I can't get it any closer, a half twist is too much at this point. The bow doesn't seem to vibrate or have any shock to me.

    With the exception of the riser, cables and string everything else on this bow has been replaced by Martin.

    OK, so we can rule that out. Being a humorous guy I was thinking it just can't handle the heat down your way. Those are some nasty temperatures.

    I don't know how much you play around changing draw weight. But I wonder if some #242 Loctite would work. It seems you've tried about everything else.

    I think 242 would work but that doesn't get me to the root of the problem. I really want to figure this out. I honestly think there are more people with it but they don't mark there bolts and watch them.

    I don't know if the heat affects the bow but it sure as shell affects me!
