Probably too long string

[Jan Poslusny]

I am proud owner of HEX5-H Mark II 38# 70" limbs since May 28. Today I raced the last competition using my prior common limbs. Subsequently, I start to set the Borders up on my Helix riser.

I bought 8125 string, 16 strands, 67.5" long with twists (67" recommended by riser's manufacturer), and I had to add 20x 360 degrees (I am sorry, I do not know if twist is 180 degrees or 360 degrees, so I use degrees) to get some acceptable BH. There are actual parameters:

string: 360 degrees on every 3cm, not curly, but near
pockets: mostly loosened (perhaps 360 degrees to allowed minimum)
BH: 8 1/4" (8 3/4 - 9 1/2 recommended by manufacturer)
tiller: 1/8", can be set from 0 to 3/8" (as recommended by manuf.)

I am afraid of string is too long. Is it wise to work on basic setup with such string? Is not it too much twisted? I would like to tune BH (but cannot add nothing), tiller, nocking point and button this weekend, to try luckily borrowed ACE shafts, if their stiffness is optimal...

One turn = 360º.

20 turns is not very much. Mine has 30+ turns. According to BCY one turn per inch would be fine. Assuming the string is brand new you will most certanly increase the twist count as the string tends to creep. It will take something like 300+ shots for it to happen. Or you may leave the bow strung for 48 hours to expedite the process (I have done so) though you will need to add some turns after a while till the string settles.

How is the bow shooting?

Thanks for information. It seems that I can add a few turns...
I prepared for a race last week, so I had not time enough for Borders. Additionally, I had not proper arrows. I still do not know, how it shoots :>)
