Rest / string / sight not aligned but sighted??

BowyerNADE · 07-17-2005, 06:18 PM

My sight pins and rest are not aligned but the damn bow shoots to point of aim what gives? The rest looks to be centered but the sight pins are right of this center yet the arrows still hit to point of aim. the pins cannot be moved anymore to the left do i adjust the rest? i will try to get a picture so you can see what i mean.

mine never lined up until i started shooting a pure bt release. some people will say its a spine issue. i wish mine didn't now that they do. i can't shoot my no-peep now because i can't see my pins thru the string. i really hate my peep.

It is common for the arrow/rest/string to be centered and the pins to be left of center. Mine are and I shoot fine out to 50 yards which is the farthest I have sighted my bow for.

you can move your rest over, the best thing to do is get a center tool there fairly cheap around $15, will center your string with your rest, also going to a drop away will make a lot of difference,, also if you are shooting with your fingers you could be torquing the string over causing it to do that,, also might try paper tuning, it will tell you how your arrow if flying and adjust it from there

I would agree. In my opinion this is not some major problem with the bow and/or your setup. Many of my setups have yielded this type of issue...without a single problem related to tuning or accuracy. Some folks would also suggest it is induced by torquing the riser slightly at full draw or even possibly the torque caused by the cable guard. I do not know if either is the case but I seem to have found a correlation with draw length. I won't elaborate further until I get a better handle on it.

Myself, I'd never accept a setup that had the pins grossly misaligned with the arrow. That tells me the bow is torquing at full draw, but not at brace, so it's obviously torquing during the shot. I'd do something to fix it.

Thinking about PABowhntr's hypothesis.... Sounds like you're talking about cable guard torque, Frank. That's a function of short bows and the cable guard pulling the cables over at a severe angle to get adequate clearance. Maybe it's also a function of the bow length to draw length ratio. (?)

After installing the Wind Stalker and floating yoke on my '04 Pro40 dually.. I had to move the sights in much closer to the centerline of the arrow/rest.. they used to sit further out . I believe this is at least partly due to the cable guard induced torque.. Now my bow just falls straight away... does not totque to one side or the other like it used to.

As you draw the bow.. the force is transferred from the string to the cables... and w/ all the tension on the cables the cable guard forces the bow to torque to the right.

I believe the cable guard induced torque is more prevalent the shorter you make the bow... also the shorter the bow.. the easier it is for grip torque to affect the bow.

I do see the bow torque somewhat when drawing and the cable guard could be the cause of the "misalignment" but as i said before the accuracy and point of impact aren't an issue.

Thanks guys for the reassurance and possible fixes!

It could be Arthur. I am definitely not ruling it out. However, I have noticed that tinkering with draw length, at least in my case, can affect this alignment between string, arrow and sight pins. As I said I haven't really looked into it in any great detail which is why I am apprehensive to comment further.

You can change where the pin/string relationship is, by simply changing your anchor position. It's pretty easy to get the pins to line up where you want, but that anchor point may not be exactly what you prefer. You can test this by having the string bisect your nose on one shot and then move it so it just touches the right side of your nose on the next.

Differing grip pressure (torque) will also change this relationship very easily. Just experiment and see how easily the string moves. Some bows are easier to torque than others. This is why any torque that's applied, must be applied consistantly, shot to shot. Of course, you're better off if you can keep this to a minimum.
