The cables are attached to the cam on one side (they are not perfectly centered). If you twist one it will shorten. When you shorten the cable it puts more tension on the cam and rotates it. Doing this is used for timing the bow so that the draw stops hit at the same time.

 

Thank you for the clarification.

Is it fair to say that in the above configuration that the two cables are applying the opposing force against the string?

Is there a point where you could not shorten the cable without first lengthening the string?

Or could not shorten the string without first lengthening the cables?

Or does it not work that way?

 

Yes the cables act in opposition to the string, but most adjustments are made through the cables. The cables also act in opposition to each other because of how they attach to opposing cams. As far as having to lengthen the string, I suppose In theory there could be a point like that, but that would take a lot of twisting in the cables or string.

 

Thank you for taking the time to explain.

Greatly appreciated.

 

Twisting up cables lengthens the bows draw length...when the cables are shortened they rotate the cams in the opposite direction as when you draw the bow. So as far as the string goes, if you add enough twists to the cables, your draw length may be longer than you want so you would have to add twists to the string to get it back to where you want it. By twisting one cable and untwisting the other as the person in the other post suggested; the DL wouldn't be affected as much (or at all) as making all the twists on one cable. The reason twisted cables changes cam rotation is because on one end, the cable is connected basically to the axle. On the other end it is connected pretty close to the edge of the cam. When you shorten the cable it pulls on the edge of the cam and forces it to rotate on that end. If you shorten the string, it causes both cams to rotate evenly, as opposed to just one. Hope this helps.

Greatly appreciated.

I hope I was able to help some. It can be difficult to explain this kind of stuff over a written post.

 

keep this in mind...twisting cables on a dual cam bow increases draw length and poundage. untwisting does the opposite. as for the string is opposite of the cam cables. twisting shortens and untwisting lengthens. the only time I fool with the string is if I had to twist or untwist a lot then I would twist or untwist the string one or two twist. if I have to twist or untwist the cables a lot, then I need new cables and string.
