What would be the advantanges of using 452X for my cables and 8125 for my strings be ? Would you have less timing issues by using the 452X for your cables but still gaining a little speed with the 8125 for the string? How many of you switch up with two different materials and what benefits do you feel you've gained if any ?

What nobody out there does this come on guys how about some feedback

Eric Griggs is currently building me a set of Ultracam cables and a TS1 string for a spiral cam experiment I am building. The reason for this is the huge amount of stress spirals put on the cables. The UltraCam will resist the stretch more readily than TS1. I am going to TS1 for the string for it's well know ability to add speed.

Send Eric an email and I'm sure he will explain it better than I.

Have heard of alot of people doing this. I myself am putting on a string made of TS1 and a cable made of 452.

Me Too!!

Eric built my cables and string the same way. Ultracam and TS-1. I've used them for a couple months with no problems. TS-1 defintely helped the speed. 3DFEVR

All the cables that I build for myself, friends and for the shop I shoot for are made from UltraCam. It is a great material for cables - no creep, no stretch and as stable as can be. The strings that I build are either TS-1 or D-75 Thin. These are also great materials, but I think they are suited for strings and not cables. Now, you can build a string from UltraCam, but it most likely will be slower than TS-1 or D-75 Thin. You can also build cables from TS-1 and D-75 Thin, but they may move on you.

The products I mention above are Brownell products, but you can substitue BCY 450X for UltraCam and BCY 8125 for TS-1 and get the same results.

I do not think it matters what combinations are used or not used, although there is a little velocity advantage with dyneema (8125, D75, etc).

Not being concerned with a small velocity change, they all seem to function fine for me, however I prefer 452X because it has a higher percentage of dyneema than the other blends.

10xring, why would you think dyneema cables would move on you if you don't think a dyneema string moves on you?

 

[JAVI]

BCY 452X is 33% Vectran and 66% Dyneema which is very stable, and I think makes for a better platform for those interested in accuracy; especially outdoors. I have experimented with various combinations and always return to the 452X.

I have heard good things about the Brownell TS1, and in my tests it held up well, but certainly no better than the 452X.

As for making the strings and cables from different materials, I see no reason to pursue that avenue; but I see no real negatives either.

My question would be; is 3 to 5 feet per second worth the headache of creep and stretch associated with the straight Dyneema or blends with a very high count of the material.

There are many other ways to gain a little speed if in fact you are part of the club that thinks speed is the cure all…

Here is how it was explained to me. The cables are under a huge amount of stress all the time, much more than the strings. Using a lower stretch material there will be better. It has been told to me that a spiral cam during the draw cylcle can see forces beyond 300lbs. You are wasting energy when you are using a more elastic material because the cable's job is to compress the limbs through the pulley system.

The string on the other hand does not see this amount of stress except right at the time the arrow is released from the string and the cam system snaps into the "at rest" position. Using a more "elastic" string like 8125 or TS1 will "soften" the shot and build a little more speed. Just because it is more elastic does not mean that it will stay that length...stretch to me refers to a permanent condition. 8125 and TS1 have proven to be elastic, but not stretch excessively over time.

Great explanation Doug!

I was wondering why we went away from steel cables then, is it cost, speed, adustability, or other? It would seem that a steel cable would be most consistent over time and different temperature conditions and with the proper length from the factory, you would never have to time your 2-cam again!

Just curious if anyone has thoughts.

Put my new string and cable on my bow, installed peep and nockloop. Getting 3fps faster than my all 452 set-up which is not bad considering that I used a full 20 strands of the TS-1 instead of only 18 strands like I used with the 452. Also shooting 2lbs less on the draw weight. Not bad, I'm happy so far. Next test is stretch which should be minimal seeing as I hung 2 50lb feed bags (******* stringstrecher) from the string for 1 week before I put it on the bow.

Fs560.....

It is mostly my opinion that I feel that an extremely stable material such as UltraCam or 452X is better suited for cables than TS-1, D75 Thin or 8125. I like having UltraCam cables and not even thinking twice about my cam timing. I do know that UltraCam will not stretch as much as TS-1, D75 Thin or 8125 (I have not used 452X) and it will seat much quicker also.

Also, I believe that the way a product is manufactured also affects its performance - % of components, twisting, etc. Thus, I like the UltraCam for the cables and TS-1 / D75 Thin for strings.

I have made string out of fast flight D-75 450 452 and 8125 I like 8125 for all it true 450 and 452 are a little slower by about 2 to 5 FPS that is nothing you can get that speed back by using a smaller serving like if you use .026 you can go to .025 or a .021 or .018 and the loss of 2 or 5 feet per second in not that big of a deal it mostly in our head Blake
