string questions

[adowns99]

i currently have a 45 lb gamemaster 2. thinking of going with 50 lb limbs. do i use the same string or do i get another one for the heavier limbs? i bought the bow used and dont know anything about the strings on these things. i got the stocj hoyt string and a second one with silencers. here is a pic of it, let me know what you think and who made the second string. thanks.

also will my 2018's with the 125 grain heads work? or will i need to put back on the 145's?

From #45 to #50, this should not make a difference for the string if both set of limbs are the same length, whatever point weight you are using, if you make or buy another string, just make sure you have enough strands on your string, for #45 or #50, a 12 strands (or 14, modern string materials do not weight much) string will do, be it in fast/dynaflight or B50 dacron.

If memory serves me b50 dacron has a breaking strengh of 75 lbs per strand so in theory 14 x 75 = 1050 lbs breakage weight , this is not gospel ... I`m sure someone else will have some figures as well .... :darkbeer:

adowns -

The string should be fine for either set of limbs, but unless you're arrow length is over 31", 2018s are too stiff (and too heavy IMHO) for either. If you're around 29", 1916s would be a better choice - yes, for both limbs.

BTW - just be careful, a lot of GM limbs are mislabled and they might be heavier than you think.

Viper1 out.

Depending on who you ask, dacron (B-50 and B-500) is 45-50# test. Every other material I know if is stronger.

The string you have should be fine for the new limbs--if it's a "factory" string, it's probably overbuilt.

It would help to know what the material is, and how many strands are in it.

I've bought two Hoyt recurves resently and don't think much of the standard strings.
For hunting their to loud and in general they use a lot more wax to stop them going fluffy real fast.
I've no idea what their made of but I've had both replaced with FF endless type strings.
The standard Flemish twist that came with my Dorado was by far the worst.
20 years ago I shot 2018's @28 1/2 from a round wheel compound,,,,their much to stiff for a 45-50lb string bow,,,and 145g just won't make that much difference.

well as you can see i'm very new to this. the 2018's are what the dealer sold me. any and all advise is appreciated here guys. thanks.

Errrr, to me B50 means that the STATIC breaking strenght is 50lbs, now don't you ever apply any dynamic strength to your string? simply put, don't you ever fire your bow :confused:? I'm sure you do :wink:
It is considered that in most cases the dynamic breaking strength for a rope made of this kind of material is about 12 times the static breaking strength, so if you draw #50, you need 12 strands.

As a rule of thumb for the bowstrings, consider that you need 1 strand for each 4lbs of poundage.

adowns, IMHO for an quiet efficient bow as a GM (if it gives back most of the energy that it stores when you fire it), I would say that the 2018 with the 125gr points "should" be ok if you really draw at least #50 (with the #50 limbs), though those 2018 are far too stiff for the #45 for sure. Now you need to test whatever works best for you, depending on what you want, so for example with the #50 limbs:
- if you want to shoot light to have the straighter flight(3D, field target), 1916 with Nibb points will be best,
- if you want to shoot heavy to have more break-through power (hunting, short distance<20 yards), 2018 with 175gr broadheads will be best,
- trade-off would be 2016 with 125gr points...

Personally, with my bow (Great plains carbon/bamboo longbow)) at my draw length I have about #45 (+/- 1lbs let say), I shoot 2016 with 145gr points, and I get a perfect flight up to 50 yards before it starts dropping fast...

thats some great info there. thanks. i've been thinking about trying the gt traditionals also. any advice from those of you who have shot them?
