Rotating peep sight

[moley101]

Recently got a compound as a respite to shooting recurve, however, my peep site rotates occasionally, it does so quite slowly and as I'm at full draw... what causes it, how do you fix it?

[geoffretired]

I think the reason is,the twists already in the string, cause uneven tensions as the poundage changes. There are two ways that I have seen used. One is to off set the peep at the start so it slowly reaches the correct alignment at full draw. The other is to use a peep that is pulled into alignment by a cord or tubing attached to the peep and the limb.

A peep sight should rotate - as long as it rotates to the same point, it's not a problem.

One thing that caught me out at first - the peep will rotate to a different point depending on whether you draw with fingers, with a release and D-loop, or with a rope release. Wen setting up your peep, you must draw it by the same method as you'll use when shooting.

On a properly made string the peep SHOULD NOT rotate.

Don't use the type of peep that is pulled straight by a piece of silicone tubing. These have been discussed on this forum before and they are worse that useless (IMO).

If your peep is rotating, it's probably because it's not in the centre of the string. By swaping strands from one side of the peep to the other, you should be able to cure the problem. This is easiest to do with the bow in a press, but you can manage without. Just be careful not to nick the strands as yoiu move them.

If you are shooting off your fingers, I would be surprised if your peep didn't rotate at first. You will just have to get used to it until you develop a better hold/loose technique. These things are much more critical on a compound than a recurve.

If you shoot with a release your peep should not rotate. Full stop!

If it does something is wrong and you shouldn't shoot until you've found it and fixed it. Most likely you just need a decent string, but just possibly the problem might be more serious - broken or loose servings, broken strands or even cam or limb issues. As I said, find the problem and fix it.

Shooting with a realease aid.
Will take it down the bow place where they know about such things and get them to look at it

You might have a problem stopping the peep rotating if the bow has the standard string fitted.Shooting in different temperatures can have an effect on rotation.
A good custom string and cable set made from 452x will be a lot better.

Depends on how the string is made and the fit too.

I have TS Plus custom strings made by Greg Hill, he does them as "zebra" method- i.e. two bundles twisted in opposite directions so the final string although striped (if two colours) has no twist in it. So when you draw it back it does not rotate so the peep does not. However, for this to work, the string has to be just the right length- after stretching in. Greg makes his end-loops without serving- that allows fine tuning of the string after it has settled as the loops can be twisted to get the length correct to a mm or so without the main string being twisted.

Some commercial strings use proprietary pre-stretch systems, but even they will stretch a little. The Matthews "Zebra" strings apparently do not move or rotate but I have not used them so cannot really comment. Winners Choice do not serve the end loops- so you can twist the loops up. So, if you have a string made correctly and fitted spot on so you don't have to introduce any twists you will not have a peep rotation problem.

If your string is the classic Dacron or twisted up type, you can install the peep and get it to come around to the correct orientation with your eye at full draw by putting it into the centre of the bundles, and moving pairs of single strands to get rotation right. Takes a while though (unless you get lucky) and you have the bow on and off the press... and it never stays the same for long. Although if you have to twist the string I have heard it said that less than 5 twists or more than 20 twists and rotation will be consistent but I have never tried this.

Well both James and I took our bows to be looked at regarding the rotating peeps. Mine was straightforward and just pointed the wrong way. A few strands moved, and it's always correct now (no rotation). James has a two-tone string, and now has one colour on each side of the peep and that has stopped his rotating, so all is sorted :-)
