I've noticed that when I’m shooting in hot conditions, my peep over rotates. I adjust my loop to get the peep to line up and the problem is solved. However when I shoot indoors where it is cooler, the peep under rotates causing me to have to make adjustments to my loop to get the peep to line up. My string is made out of 452X. Is this just the natural of the 452X string material? Is there a string material that isn't "heat sensitive"? Or is the construction of the string to blame?

Thanks for your help in this matter.

Is your peep rotating when drawing the bow or before you draw the bow it has already rotated. Sounds like the string may be imbalanced, if it is rotating during the draw cycle the string is imbalanced meaning on side of the string is tighter than the other.

I am not sure there is one that is not heat sensitive? Heat and cold effect strings 452 and 452X maybe the least effected compared to 8125.
Not sure bout the Brownell product line?

 

[JAVI]

Try this...

 

[mtboho]

Great question, and great literature javi, I have one question to add to this. What about black strings? do they move more than a light colored string in heat or sunlight? I overheard some shooters talking about string color and effects in heat. didn't catch it all and they left before I had a chance to ask them any thoughts on this?

String turning>

I also have found the string material 8124 and 450 both turn the peep in hot and cold weather changes.

I still shoot one of my bows, ( PSE INfinity ), that has the dacron string and steel cables on it.

The string on this bow does not turn the peep at all during any type of weather.

Dacron was given up because it is not as fast as the fast flight strings being made now, but they do not turn in any type weather.:wink:

 

[crazy horse]

Dacron strings do not twist because they are conected to metal cables that are not heat sensitive. Hot weather (tempetures) are going to affect most strings to some degree. As long as your adjustments does not affect you accuracy its not that big of a problem, usually your peep is just going to rotate a little, nothing to be to concerned about.

Vaportrail and WC strings are nearly un-phased by temperature from my experience.

I use to run into the temp. problems as well, especially since my "archery corner" is right near the strongest A/C vent. I switched to Vaportrail VTX strings a few months back and found them to be FAR less temperature sensitive than any of the customs I've tried. The peep remains aligned whether I'm shooting indoor at 55 degrees or outside in 100+ weather. Not so much 100+ as of this week since thankfully, the sun decided to take a break.

A friend of mine, who I shoot with often, uses WC strings and I've noticed he doesn't have any peep rotation problems either in cold or hot environments.

As far as I understand, VT and WC strings are constructed of pretty much the same stuff as anyone else out there... which leads me to believe that there's something in the construction process or perhaps an additive that gives those strings such excellent temperature resistance.

 

[RobertM]

To clarify just a little, the peep is rotating before the bow is drawn. If the temperature remains the same, I can get the peep to line correctly everytime. However if the temperature changes the peep will not be the same. This is causing me to have right and left misses and when there is a huge difference between what the temperature is when I set the peep alignment and the temperature of the area I'm shooting, I can't see through the peep.

I made the string without pre-stretching it. I just laid out the string, served the end loops, then put the string on the bow and let it sit for a little while before serving the center. My previous string was a WC and I didn’t have this issue with it. Any suggestions?

How long ago did you build it..?? More than likely it just need to settle a bit more..

Yep, had that same problem with every aftermarket string I tried up until Vaportrails. I already knew WC would've keep my peep inline as that friend I mentioned has used WC since forever. Always trying to get me to switch over too. I think that's why I never did go with WC, cause he kept nagging me about it. In retrospect, I spent waaaayyy more money trying the others than had I just gone with WC in the first place.

I found with some of the custom strings, that after exposing them to REALLY cool temps and twisting nearly 1/2 around that they wouldn't recover back to normal after returning to room temperature. I'd have to shoot them in again before the peep would roll back inline. And sometimes, that meant 100+ shots which was phenomenally irritating.

If you do happen to figure out how to remedy this problem, I'd be interested. I have about 7-8 sets of different aftermarket strings sitting around collecting dust as backups.

 

[JAVI]

Usually it is a product of how the string is laid out and served.. Most of the time a little twisting and thread swapping will fix it...

 

[CoppertoneSPF15]

Yea... I tried the twisting and the thread swapping via your guide. That would align the peep straight and true and keep it from rotating through the draw but in real cold or hot environments, that peep would flip out. Not so much during the draw but at rest. The peep would rotate nearly half way around just from being near the A/C vent for an hour. I'd rotate the dloop to pull it around to align properly at draw but that was what I wanted to avoid to begin with. Any ideas?

 

[CoppertoneSPF15]

For reference, some of the customs I tried were Bowmans, H&M, Bucknasty, Stonemountain. They were all pretty darn good strings. From a visual standpoint, they looked great. After setting up and shooting in, the servings held good... stayed nice and tight for many shots thereafter. But when these strings toed up with my A/C, the problems began. Ran into the same problems under a hot sun, the peep would just twist in the opposite direction at rest. Frustrated the crap outta me.

This is the exact issue I'm having.

JAVI, I built the string about 2 months ago, so I'm pretty sure it has settled. I use your method to get the peep to line up and if the temperture remains the same, the peep will line up. However, if the temperture changes (hotter or colder) then the peep will not line up. But if temperture returns to the initial temperture, then if peep will once again line up. This becomes very frustrating.

Did the string twist any at all when you served it..

All string material will react to heat and cold by temporally elongating or contracting. 452X is roughly 30% Vectran a material known for its stability in varying extremes, but even steel will shrink in cold and grow in heat. The real problem is the twisting and I suspect that the string twisted during the serving process or the extra twists have not settled under the servings completely.

 

[boojo35]

You said you maid the string without prestretching it. That probably is the problem. You need to stabilize a string and tension it before doing any loops or end servings or you end up with unequal strand lengths in the string. I make custom strings and I use both 8125 and 452x and dont have any problems with either of it.

 

[RobertM]

What's the best process for prestretching a string? Like I said before, I took the string off the jig and put it on the bow. I thought that the bow would prestretch the string. Is more tension needed to prestretch the than what the bow can provide?

JAVI, I thought that the twist unde the center serving might have been the problem. So I removed the center serving and re-served it. However I still had issues when shooting in hot and cold conditions.

Thank all of y'all for your help.

 

[Deezlin]

Is your peep rotating when drawing the bow or before you draw the bow it has already rotated. Sounds like the string may be imbalanced, if it is rotating during the draw cycle the string is imbalanced meaning on side of the string is tighter than the other.

Of all the materials for bow strings, I think UotraCam is the most stable for peep sight rotation. Especially in cold weather. The only problem with it is, it is a little slower too.

pblawler is right. If you are going to shoot in these types of weather condidtions I would have the string setup for it. In cold weather, I would leave the bow in the vehicle or someplace where it would be at the hunting temperature.

Then, I would press the bow and move one of the strands from one side to the other of the peep. It that didn't stop the rotation, I would move another. Eventually, the rotation stops. Now you may have to move several more, equal numbered strands from one side of the peep to the other until the peep properly orientated.

However, generally, a well made string doesn't have theses problems.

What about the end servings?
