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.

I disagree. It should not be more than 10 turns per side though.

Can you explain why, Simon :)

There is no need to limit the revolutions to just one. As the barrel nut will turn inside the riser and the limbs are sitting in the limb cup on a ball the limb can handle also more revolution.

I chose 10 full revolution because it is possible that the limb is relaxing a little bit too much. I might not hurt at all but it is something noone needs to try out.

That's a good point! You're right, but i just prefer some extra security when i work on a bow for which i've given 520 euros :D And i always try to give equal number of turns on something with more then 1 bolt - a lesson from my grandfather :)

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.

There is no need to limit the relevations to just one. As the barrel nut will turn inside the riser and the limbs are sitting in the limb cup on a ball the limb can handle also more relevations.

Simon, you do pretty well most of the time. You goofed this one only in that your spelling is off a bit. You do not mean relevations. It's revolutions. Other than that you're spot-on.

Oops. You are right. Better check words next time before using them.

Oh guys, wish me luck. Going to the next exam in 30 minutes. Interested in the topic? It is
'Sensorische Informationsverarbeitung und Verhaltenskontrolle' meaning something like 'sensory information processing and behavioral control'

Is first-grade enough? :)
Among our system of marks between 1.0 (best) and 4.0 (worst) i got a 1.0 :)

Congrats :) Your system is quite strange for me - ours is 2 - worst, 6 - excellent.

Good grades like that mean you either are studying hard or just have a natural sense of the subject. In either case I applaud you on your acheivement. So when do you get the time to shoot a bow?

I have a small competition at August 29th. I hope i will be able to shoot at least two times to setup my sight before that date. :D

Thank you guys!
