    Default limb bolt length

    i have a martin lynx magnum compound bow. I would like to know how long the bolts are to the limbs? The full length of the bolts not just thread length. Any info would be great..

    Don't know sorry but why if you don't mind me asking? Did you loose a bolt or are you wondering if you can disassemble the bow without a bow press?

    well, neither. The bow should be able to be set at a 45 lb. draw weight. I've loosened the bolts to decrease the poundage, but it only helps slightly. I was just wondering how far i could loosen the bolts and still be safe. I just wanted to know how long the bolt actually is.

    Should get about 3-4 lbs drop each turn. What is the peak weight?

    peak weight is 60. It should go down to 45 but i don't know how far to go out with the bolt. I need it to be 45 so I can shoot.

    5 full turns of the limb bolts should make 15# less. You must make 1 turn on each bolt one after another.

    What difference does it make how long the bolts are?

    I can tell you that they are long enough to completely relax the string, without backing all the way through the barrel nuts.

    Just because there are still threads engaged, doesn't mean that it is safe to shoot the bow that way!

    Back the bolts out one full turn, and measure the draw weight. Repeat that and adjust to fractions of a turn as you get it close.

    If your string is stretched a lot, your draw weight and draw length, are already higher than you might think. If that is the case, you need to take the bow in to a shop for a new string.
