D97 strands per lb chart

[kybowman]

This question is for all the D97 skinny string experts. Anyone have a chart showing the strands per pound of draw weight? What is considered nominal, not pushing the envelope?   :confused:  

thanks

I have been making and shooting 8 strand D97 for bows up to 58#@28 so far without any problems.They are quieter then my 12 strand D97,I've going to try 6 strand for a 45#@28 bow I have.But 8 strand has been working great on my bows from 45# up to 58#,and I do pad my loop ends to make the ends a larger diameter to better fill the string grooves.

6 strands to 50#
8 strands to 60#
10 strands to 70#
etc...

these numbers are imho very safe, conservative.  some will tell you that you could get away with more, and you can. this is what i consider not pushing the envelope.

with proper care how long will these strings last

What is the breaking strength of one strand of D97?

Thanks guys!!!

Dynaflight is rated at 125# test per strand, or used to be when BCY published this data.  It can vary though.  Pretty sure they won't put out a "tiny string" chart due to liability concerns.

I personally am not comfortable with "just enough".  Tiny strings are more susceptable to getting cut, wear, etc.  I don't like to go with less than 8-10 strands, even on light draw weights.

CJC's chart is good.  However, I have been using 6 strands of DF97 with loops padded to 16 on several bows in the 52-54 lb range and have had no problems whatsoever with either creep or outright failure.  On my 57 - 60# bows I use 8 strands. Some of these strings have been in use for a year or so. I actually don't know that there would be a detectible difference from 6 to 8, so when I rebuild new strings I will likely just go with 8 strand for all of my strings for the sake of uniformity.  I have to admit to being a little apprehensive when I first began using the skinny strings, but I am sold on the idea now after a lengthy trial period. I do wax and inspect my strings regularly, but I don't see the need to replace them any more often than  12 strand with proper care.  If one strand frays or gets cut I replace the string anyway, whether 6, 8 or 12.

The issue with low strand count dyneema based strings is not so much the strength but with the creep. Low to no creep materials such as BCY450+ or Ultra Cam are in my opinion better suited to low strand count strings not so much because of a strength advantage but because of the lack of stretch and creep in the material. I shoot an eight strand Ultra Cam string on a BW PAX 60#@28" that has been rock solid for over 1000 shots and I may go to six.

are those numbers for 28 inch draw?  if so what does a shorter or longer draw due to the chart.  It seems like powerstroke should have an effect.

Would six strands of D97 hold up to 60#@28"???????  :eek:

[CJC]

thats  pushing the envelope.  why chance it?   8 is way more sensible!

[Oliverstacy]

An 8-strand D-97 is skinny...an 8-strand 8125 is even smaller (noticeably)...how small must one go?

I had a 12-strand D-97 sent to me for an actual measurement the other day...it had two strands cut, one of each color/bundle!  You cut one strand each on an 8 strand string and your down to 6...and so on...be careful!

I wouldn't try it, it would likely never stop creeping. That's why I switched to 450+ and then to Ultra Cam. For a good stable and therefore safe skinny string you have to be able to eliminate the creep.
