Center shot string method

I used a piece of string to tie a line from one limb bolt to the other abs create a vertical line in the direct center of the limb and then cut an arrow off so that it would barely reach that string and then look at the bow from the target side of the bow to line the string up in the direct center of the arrow. Any reason why this would not be a fool proof way of finding the precise center shot of a bow?

Centershot isn't always center of the limb bolts. Depends on the cam system. Many have the string set to the off side of the cables, the cables pull to the cable guard, that's why you often run a biased deflection on the limbs.

Easiest thing is setting rest to the manufacturer suggested center shot, then tune to find exactly where it needs to go.

And to clarify tuning doesn't always mean moving the rest, I might move the rest slightly left/right but if it needs to go more than a 1/16 I'm definitely twisting yokes or shimming. Usually I'll just set rest to spec and shim/twist to tune.

Ya I have always set it to manufacturers recommendations and then tuned it in, just saw a video of this method and tried it on my prime centergy and it ended up being exactly 7/8” anyways.

If you need a visual way the easiest fool proof method is to hold a bare shaft against the inside of the riser and ensure your nocked arrow and this arrow are running parallel. Like previously mentioned this will only get you close, depending on a ton of other factors you’ll likely need to give it some love one direction or another by 1/32. I get a rough tune at 20 and then line tune at 50 for my intended point weight. It always falls within the range set by the mfg.

The string isn't in the center of the bow. Set your rest to 13/16, move the cams or the rest to get a bullet hole so you know the string is pushing straight behind the arrow, then go tune the bow.

Do you mean in general or for a prime centergy?

In general, YouTube search Horizontal Nock travel and you’ll see some good videos that will give you some good stuff to think over. Most bows made today are much better than the bows of old in regard to this.

Most cams are offset because of the buss cable side, centergy looks to be centered from what I could see on the net. You still have a cable guard and will have some lateral nock travel but your string method will get you close.

Ok thanks. Ya there is a guy that does a bunch of nock travel testing and centergy was always towards the top of his lift for minimum nock travel.
