    Overloading limbs ?

    Hello all ,

    First post here ,
    I did do a search but couldn't find anything on this subject.
    I started doing archery about a year ago , enjoying it, and trying to learn as much as possible
    about bow set up and tuning
    I am shooting a recurve bow, 25" WNS riser 68" WNS limbs
    My limbs are 30# . Recently I have been mucking arouund wth tiller bolt settings etc, to
    get a set up that works.
    I went to 30 # limbs , because I am 61 years old, and thought that would be my limit for a while.
    but this morning I rigged up a jig and scale system, and noticed that the actual pondage at the fingers
    is about 36 # at full draw ( 29.9 " draw length )
    This really surprised me !
    My question is this : Am I overstreching my limbs, or is this nothing to worry about ?

    Thanks in advance

    Thumbs up

    They should be fine. It depends how the bow/limb manufacturer rates their limbs - is it full wound out/in or half way, and it usually assumes a 28 inch draw. A draw length under 30 should be no problem. My barebow limbs are 40 lbs off the fingers on 36lb rated limb.

    If you are measuring draw length to the button or throat of the grip you must 1.75", to give the AMO draw length. That's what the manufacturing organisation says is your correct draw length.
    Your poundage isn't a problem, more it's how far you are drawing your limbs. If your actual draw length is 29.9" you are just about ok for most limbs making a 68" bow. If it's really 29.9+1.75=31.65" you are probably over drawing and risking a breakage.

    It's always worth remembering that some modern manufacturers state that you will void their warranty if you exceed their draw length recommendations.

    Thanks guys,

    I measured the poundage with the arrow.
    Pulling back untill the clicker went off. To me that seems the most representative for the
    real situation.
    The arrow is 29.9 inches from groove bottom to front of the tip, so I consider that my draw length.
    Maybe for my next limbs I should get long ones ( 70 " bow) ?
