How to Adjust a Compound Bow
Arm bolts are large circular knobs near the center of the bow that connect the bow’s arms to the riser and must be manipulated to adjust the draw weight, or the amount of tension placed on the bow string as it is pulled. The draw weight of the bow should be determined by your level of upper body strength. An excessively heavy draw weight can wear you out and throw you off.
Choosing a weight that feels comfortable in your hands is important; don’t let ego tempt you into using something that isn’t right for you. Draw the bow with your feet off the ground and hold it in position just before the “wall.”
Can you adjust bow draw weight at home?
To adjust the draw weight, tighten or loosen the limb bolts to unload or load more stress (flex) on the limbs. To raise the draw weight to maximum poundage, tighten the limb bolts (clockwise) until both limbs are tight against the riser.
Does changing draw weight change draw length?
It doesn’t change the draw length, but it does change the brace height due to a slight change in the geometry of the limbs as you crank down the pockets – the bases of the limbs are twisted more vertically, causing the limbs to bend more, lowering the BH.
