Title: BCY D97 Flemish Twist question
Post by: Bongos on January 24, 2013, 01:06:00 PM
I started making my own string with D97, I really love the string material.. most of my recurve bows range from 40#-55#.  After much research here and other sites, I decided to make 8 strand strings with padding (12 strands on the end loops).. well, I just got of the phone with Hummingbird Bows because I had a question on the brace height for his Kingfisher.. we ended up talking about number of strands and he recommends 12 to 14 strands for his bow, this is for my 48# recurve...  I made one but your thoughts and comments are appreciated as I've made a couple of 8 strand strings already for my other 45# bows.. are these safe to shoot?

Safe.  Probably.  It scares me to look at anything under 10 strands.  I generally build 12 strand D-97 strings, padded to 16 in the loops, for my 50-55# plus bows.  Probably more than I need, but I don't see a worthwhile advantage to going lower than that.  Even at 8 strands, I'd recommend padding the loops to 14 to 16 strands.

I usually make mine 14 strand for my 55# BW PLAX.  If I make them less, then I have to build up the serving to have a snug fit at the arrow knock.

I just got off the phone with Black Widow and they said all of their bows use D97 and 14 strands.. no padding..
Thanks Gents for your comments, please keep it coming as I am absorbing it like a sponge...
I've taken all of my 8 strand strings and put them away lowere poundage bows..(30#-35#).. guess I got some strings to make

I have made either 8125 or D10 strings for 6  bows.  The bows are all 66" and either Hill or R/D style 48 to 60 lbs. All the strings I have made for these bows are 8 strand with loops padded to 16.  At least three of the bows have thousands of shots without one problem.  I did have one 44 lb. bow that I made a 6 strand for and it too worked fine.  If you look at the strength of the individual strands, 8 strands are plenty strong for your bows.  Also, look at the custom string makers and what they are offering. If I'm not mistaken, Pierre @ Silent But Deadly offers 6 or 8 strand strings.  The only issue I have had with skinny strings is getting the proper nock fit - beyond that, I love them.

Sorry to get a bit off topic but i have been dwelling on making my own string for my ron pittsley predator classic 60# bow. Can somone point me in the direction to make my own d97 strings, and reccomendation for my bow and poundage? i have tried the search but i dig myself a hole and i get lost honestly. Sorry again, and thanks for the help in advance.

I make a 8 strand D97 for my bows under 55#,a 12 strand D97 is strong enough for upto a 100# bow.I shot a 12 strand D97 on my 73# 21st Century and a 83# Bamboo longhunter I had.

This is the jig I built, the drawings of this jis is located here in Tradgang (you have ot look in the archives).  The pegs are AMO lengh of the bow, not the lenght of the string

There are great pointers from this one as well

You are welcome, total cost of Jig buying components (wood, nails) from Home Depot about $9

Initially I bought B50 dacron but have since migrated to D97 (apparently one of the best strings for recurves)as a beginner,D97 is inexpensive compared to others and D97 string come up often in the Classifieds here at a discount. I'll just save the dacron for older bows... Good Luck

Ive shot 8 strands on 60 - 70 pound bows for the past two years without a problems, 6 strands on lighter bows.  Build the loops and center area up with extra strands to distribute the force and so nocks fit.

The only negative about an 8 strand D97 string is that they will continue to stretch. I much prefer to use 10 strands with D97. If you want a skinny string, you will be better off using Ultra Cam or XS2 (I use 10 strands of XS2 because it's a thinner strand material)

for building the loops can you just wrap the loops with yarn? for example like the hush puppies?

I shoot 8 strands of D97 on bows up to and little over 55#.  The longbow strings seem to creep very little.  The recurve seems to creep a lot more.  Maybe it is a matter of preload on the limbs, I am not sure.  

Fishburglar, I would use D97 or dacron to build up the loops.  You are protecting your limb tips by building up the size of the string.  Yarn may not be stout enough.

My preferred material for "skinny" strings is 8190.  Small strands, so you don't have to go low in strand count to get a small diameter string, and very strong.  14-18 strands is still a small diameter string.  452X and Trophy are also good--small diameter strands, very low stretch/creep.

That's the bows I shoot, using D97 with carbon I use 16 strands and crown .026 serving. With wood I use 14 strand and .025 braided or .030 braided. I like to pad to 16 with the 14 strand but rarely do it.

I'd go with 12 strands, loops padded to 16-18, with .025 62XS or .024 Halo for center serving.

No.  Padding the loops is quick and simple.

We have a couple of videos out that covers making a string start to finish, including padding the loops:  "Doin' the Twist" and "How to Build a Great Bowstring".

DTT focuses mainly on Flemish strings, but covers building an endless.  It also contains plans for making a string board and string stretching jig.

BGB covers flemish, but also goes into more detail with endless.  The camera work is better with BGB.

They both contain information and instruction not found in the other, but both cover making strings start to finish.  No shortcuts, nothing left out, no mystique or smoke and mirrors.

I LOVE THIS SITE! THANK YOU GUYS SO MUCH. I JUST WANT O MAKE MY OWN STRINGS AS I WANT TO EXPERIMENT WITH DIFFERENT STRANDS AND SILENCERS. PLUS SOMETHING TO ADD TO MY KNOWLEDGE. FOR MY PREDATOR I KNOW IT CAME WITH A D97 BUT IS THERE A MATERIAL BETTER RECOMMENDED FOR PREDATOR RECURVE?

WHY WOULD YOU USE MORE STRANDS WITH CARBON AND LESS WITH WOOD? I WOULD EXPECT IT TO GO THE OTHER WAY AROUND.

8190 is a higher grade of Dyneema (SK90 vs SK75), but Dynaflight '97 is a great material when used properly.

Just for nock fit, I don't think a 2 strand difference does much. As you can tell, not a skinny string guy

Nahh--just don't try to use 6 strands on a 50# bow, because it will stretch and creep a lot--especially in higher temps.

 
QuoteAs you can tell, not a skinny string guy  
Me either--or at least I'm not a low strand count guy.  With 8190 you can still get a smaller diameter string without going minimal in strand count.

well, just an update, I've settled on 14 strands for 45-60# bows, with no padding needed and .026 serving, it provides the perfect nock point and very little creep, I just leave the bow strung for a day, I check it everyday and shoot about 50-60 times and the creeping stopped (usually about a couple of days.. I unstring.. picked it up a week or two later and the brace height was the same). I find 12 strands takes a little longer but I'm sure I'm losing 3-5 fps in going with a higher strand count..it's not a big deal to me on the speed

I'm certainly no expert with regard to string making, but I am a "if it's not broke don't fix it" kind of guy.

I've been building my own strings with D97 for the past 12 or 13 years. Originally I used 12 strands, no loop padding, .025 braided center serving, bows ranging from 50lb to 60lb.  Nock fit for GT and CE required a slight bit of sanding with an emery board.

 About 3 or 4 years ago, when the "skinny string" posts were rampant, I tried a couple of 6 strand strings for the lower poundage bows and 8 strand for the 55 - 60 pounders.  After experimenting with various center servings and shooting the skinny strings for a awhile, I finally settled on 8 strands for everything, loops padded with 4 extra strands and center served with .021 braided, double-served in the nock-tab area.

Nock fit with GT's is perfect without any sanding and durability is excellent.  I usually build a new string once a year for the bows I shoot the most, even though they look good and show no signs of wear.

I shoot mostly HH bows around 55# and I shoot almost every day year-round 40 - 60 arrows. I leave the new string on the bow overnight to stretch it when I first make it, but after that I never have to adjust brace height - it just doesn't stretch or creep.

There may be better materials out there, but for me the D97 8 strand is quiet, no stretch, fast and durable, so I'll keep using it.
