Title: Skinny Strings
Post by: JamesKerr on January 25, 2012, 04:58:00 PM
I just got off the phone with Art at 3Rivers Archery and he did not recommend using a skinny string for my Tomahawk or any bow as it transfers more vibration to the bow than a standard 14-18 strand fast flight string. This vibration he said is very akin to shooting too light of an arrow and can cause limb failure. I was just wondering if any of you bowyers recommend skinny strings or do you think that Art was right in that it creates too much shock.

My bows have left here with 8 strand 450+ for a long time now. No problems at all.

I shoot the same stings on my self bows too.

With all the skinny string rage going on over the last couple years that's the first I've heard of that. I shoot 8 strand and 10 strand strings with padded loops in a 54# and 62# bow, no failures yet but that doesn't mean much either.

I haven't heard that,I've been shooting 8 strand D97 and 6 strand 450+ of my bows 60# and under for the last several years.Haven't had any problems at all,my bows are quieter and perform just great as always.I'll use more strands on my heavier bows.

I shoot 8-strand SBDs on all my FF compatible bows. No problems.

I think he has it exactly backwards! I get less shock (vibration) by far using a skinny string. The analogy of the light arrow is incorrect as well since more of the energy is transferred TO the arrow, thus away from the bow.

To clarify Art said that it probably would not cause damage but that there might be a problem in the long run. I took mine off as I did notice more vibration than with my 14 strand string, and I feel it is always better to be on the side of caution.

If 3Rivers sold them his story would be different is my guess. Skinny strings are not new. Ron Leclair has been sending them out with his bows for maybe 15 years?

Yeah Ron That skinny string did make quite a bit of difference. Working on saving up some $ for a new Abbott, but will not be letting this one go!!!
This was for an Abbott longbow that I sold. I have very arthritic wrists and elbows and the bow definitely had a lot of hand shock. My theory is that the extremely heavy string was flying far forward due to inertia, and oscillating causing the limb tips to vibrate. Cliff's skinny string seems to have helped.

Every bow seems to like a certain string better and that is exactly why we offer both the skinny and standard string configurations.  I own a Shrew CH and it came with a "skinny" string.  When I put a more standard string on it, I get some hand shock that wasn't noticible with the skinny string.  I also have a Dwyer Dauntless that came with a "fast flight flemish twist" string and when I switched to one of our FTS Super (continuous loop) strings, it gained an average of 2 fps in speed and it was even quieter than the original string was.  Interestingly, the speed difference was likely due to the cat whiskers that Dave puts in his strings.  (Our FTS Super string does not come with whiskers installed.)  Thinking that maybe I could get my Shrew even quieter, I tried the same thing but I didn't really notice any difference in sound and I didn't measure any difference in speed.  

Now it is very important to note that some bows should not have the "skinny" strings on them at all as it could damage them.  This is particularly with the older bows.  Following the advice of the bowyer is always the best policy (if you can)!  We have often been asked if it's ok to use one of our FTS performance bowstrings on a certain makers bow and we always recommend that they follow the advice of the bowyer!

You have to go with your own experience.  There are few if any "one size fits all" answers in this sport.

It's also a good idea to follow the advice of the bowyer/dealer, in case you have a problem down the road.

I'm sure if they wanted to, 3 Rivers could sell "skinny" strings.  I won't go as low in strand count as some offer--not because I can't, but because I'm not comfortable with them.  I won't sell something that I won't use myself.

It's just different experiences and different opinions--like a lot of other things in this sport.

A question here, When does a string cease to be skinny and become just a regular string?  At how many strands?
Title: Re: Skinny Strings
Post by: LBR on January 25, 2012, 08:34:00 PM
"At how many strands?"

Depends.  10 strands of 8125 is going to be smaller in diameter than 8 strands of 450+.  12 strands of the new 8190 is a very small diameter string--as small or smaller than 10 strands of 8125.

I've never measured actual diameter--I just look at it and know if it's "skinny" or not.

Mike, a regular string on some bows are "skinny" strings!  It's really up to the various bowyers isn't it?
Title: Re: Skinny Strings
Post by: Overspined on January 25, 2012, 10:22:00 PM
Some bows just don't respond enough to where it matters. I happen to absolutely prefer skinny strings w/ padded loops on my Hill bows.
Title: Re: Skinny Strings
Post by: M60gunner on January 25, 2012, 10:24:00 PM
I am confussed (not new for me) what is the issue? The string not strong enough or the string cutting into the limb tips. I have a couple of bows with "skinny" strings. I had them made by a fellow club member. He padded the loops and so far no issues. My newer SK is quieter and seems to preform better.Thanks, Tom M

Been shooting either 6, 8, or 10 strand D-10s, with padded loops, on my bows, in the high 40's to low 50#s with no problems. Probably won't order any more 6 strand strings, not that there is anything wrong with them...they just don't look right.
I think some companys won't sell lower strand count strings on account of having to mess with serving/nock fit and loop padding issues. It's much easier for them to twist up a 14-16 strand string and send it down the road busting bugs.
Title: Re: Skinny Strings
Post by: SlowBowinMO on January 25, 2012, 10:32:00 PM
Most skinny strings are simply not needlessly overbuilt.  All my FF compatible bows wear 8 strands, and 8 strand D-97 and D-10 has been original equipment on our Fireflies for several years.  They simply shoot better, at least on our bows.

Quote...what is the issue?
Not so much an "issue" as a "trade-off". Everything had trade-offs.

 
QuoteI think some companys won't sell lower strand count strings on account of having to mess with serving/nock fit and loop padding issues.
I can only speak for myself--for me, it's a liability concern.  Look at BCY and Brownell's sites--see what they recommend for strand counts.  I pad the loops on all my HMPE strings unless asked not to, and doing a serving and a half might add 2-3 minutes to the build.


Like I said before, it's a personal call.  If they work for you, shoot 'em.  If they don't, don't feel like it's the end of the world.  There's been a few folks down the line that have done pretty well with dacron, even linen, silk, etc.  

Ever watch any old Ben Pearson, Fred Bear, Howard Hill, etc. videos?  Their strings often looked like they stole a clothes line, but they managed to get the job done, on targets and critters.  Even earlier on the archery scene were these guys by the name of Saxton Pope and Art Young...maybe you have heard of them...  :archer:

So if I used 8 stands of B-55 and an extra 2 in the serving area so the snock would grab, on a 43# bow is it considered skinny?
Title: Re: Skinny Strings

I'm reading that JamesKerr was told that skinny strings given some time will lead to limb failure due to added vibration. That's a charge that if true some proof ought to be provided to substantiated it. Either it's true (give examples) or not true, or is this just an unfounded opionion.
Title: Re: Skinny Strings
Post by: Steelhead on January 26, 2012, 02:55:00 AM
I cant see limb vibration being a problem with a well built skinny string and good silencing.In general the limbs and string seem to dampen out faster and the bows seem to shoot quieter to my ear and you increase the effeciency of your bow to a small degree.Thier can be less felt handshock and handshock is the result of vibration.I am not buying the more vibration theory from my personaell experience with shooting alot of skinny strings for quite a few years of many different materials.All had built up loops and were well made.Most were 6,8 and 10 strand strings.Differnt materials will give you different circumfirances as mentioned by LBR.

All bows are not the same though and each bow will have a material,strand count and silencer placement,brace hieght and arrow weight that it performs best at as far as vibration,efficiency,quietness and shooting comfort.

Nothing wrong ar all with using a fatter string.They are very durable,last longer and will withstand more abuse from abrasion and work just fine.Thier is some peace of mind using a fatter string.

I think you should replace a skinny string sooner than you would a thicker string when it starts showing signs of wear that concern you to be on the safe side.

I am not sure if I would use a 8 strand B-50 Mike?Maybe 10 to be safer.I like 12 and have used that alot on Vintage Bears of around 50#s draw.
Title: Re: Skinny Strings
Post by: Rob DiStefano on January 26, 2012, 07:18:00 AM
low strand count, or "skinny" bowstrings will Never be a problem for any stick bow provided the bowtring strand material is a form of hmpe (i.e. - ff, df'97, d10. etc - "dyneema", "spectra", "vectran", etc) and the string loops are padded for some measure of cushioning thickness.  read that again.  that's all there is to "skinny strings". done right they're perfectly safe for ALL stick bows that are built for modern string materials.      :readit:    

the average hmpe fiber has a tensile strength of over 100# per strand.  let's do the math ...

the typical bow/bowstring tensile strength ratio is 10:1, which means that a 600# tensile strength string is good for a 60# stick bow.  

a 60# stick bow with a 14 strand hmpe bowstring will have a breaking strength in excess of 1400#.  think about it.  that's overkill in the tensile strength department and a bow holding weight to bowstring tensile strength ratio of 23 to 1.  drop the strand count down to 8 and that 800+ pounds of tensile strength now has a strength ratio of over 13:1. hmmmmm.       :saywhat:      

change the hmpe (polyethylene) to dacron (polyester), with its 50# per strand (actually, less) and it takes a 12 strand dacron string to equal that 10:1 standard.  add in 2 strands for a 12:1 ratio if that makes ya feel more comfy.

these are the facts when it comes to bowstring strand counts.  do with it what you like.  some folks just don't like the idea of an 8 strand bowstring, and feel there's a margin of durability missing.  some talk about string noise and others are concerned about arrow speed.  there are LOTS of other likes/dislikes about bowstring materials and strand counts.  pick whatever makes you happiest and go kill something, 'cause that's what they all will do regardless of what you, i, and others think.  it's all good, just do what you want.  but do it safely and with the facts.     ;)

If a bowyer guarentees their bow with a 16 strand string and at least 9 gr/in arrow, then you shoot it with either a less than 9 gr/in arrow OR a less than 16 strand string, then I'd say the bowyer would be off the hook should the bow blow up on you.  I most cases, we're either shooting arrows that weigh more than the minimum and/or added weight to our strings with silencers and the point becomes mute.  "Skinny" strings are nothing more than a simple bowstring made of modern hmpe material that is not grossly overbuilt.
In my opinion, those overbuilt 16 strand hmpe strings have so little stretch in them that they put more stress on a bow than a 6 or 8 strand hmpe string that "gives" a little bit like the old dacron strings did; which I suspect is a part of why they tend to be quieter.
Title: Re: Skinny Strings
Post by: Swamp Yankee on January 26, 2012, 07:45:00 AM
Oh yeah, string to nock fit is more a function of the serving than the number of strands in a string.  In the case of "skinny" strings, I consider padding to be just part of the serving as it adds nothing to the basic strength of the string.
Title: Re: Skinny Strings
Post by: Mike Mecredy on January 26, 2012, 10:53:00 AM
With the bows I build and sell, I provide a B-55 string,  (B-55 is a little thicker than B-50) the ones up to 45# I use 8 strands, for 50# - 55# I use 10 strands, for 60# I use 12 strands. Sometimes for one between 45# and 50# I'll make a 3 bundle 9 strand.  I haven't had a problem.   To me there's not much worse than an over built string.  But if you do this, make certain the tips are reinforced and the string grooves are radiused around the back of the bow to give the string loop smooth continuous bearing surface.  That will keep the tips from spliting, and the string will last longer.

Agreed. I hear this all the time too, but have never seen evidence. Has anyone actually had a modern bow "blow-up" as a result of using a skinny string? If so, let's hear about it.
Title: Re: Skinny Strings
Post by: Mike Mecredy on January 26, 2012, 11:42:00 AM
Not exactly modern, but I repaired a few Damon howett hunters that had the tips split about 2" up from using thin low stretch materials.  But had the tips been reinforced and fashoined for low stretch string they wouldn't have.

Also, vibration can be dampened with the use of limbsavers or string silencers.  If you can feel it or hear it it's there, if you can't it's reduced.

Post by: JamesKerr on January 26, 2012, 11:54:00 AM
I switched back to my 14 strand string as when I shot my 8 strand on my tomahawk it was a little louder and did add a little more vibration to the shot. That being said I am a hunter and want as quiet of a setup as possible. The extra 5 or 6 fps wasn't worth it to me.

What do you consider "overbuilt", and why are they so bad?
Title: Re: Skinny Strings
Post by: Bladepeek on January 26, 2012, 12:59:00 PM
Not related, but in a way it is. When homogenous steel barrels were introduced in shotguns, many shooters rejected them because they considered them unsafe and they caused a bad "ringing" which was painful to the ears of the shooter.

I have a 42# D type longbow that the maker puts a 15 strand B-50 string on because "it's quieter". He does not recommend a FF string. I am going to try a heavily padded 10-strand FF string and see what effect it has on vibration and noise. If it improves things, I think I will grind off the tip reinforcement and put some micarta and horn on the tips. I really think this bow is being held back by that heavy string.
Title: Re: Skinny Strings
Post by: Mike Mecredy on January 26, 2012, 01:10:00 PM
LBR It's a waste of materials.  That doesn't bother most the way it does me.  

I use the amount of strands required on my bows.  If someone wants a bows string from me, and I only know the length of the bow, I have never seen it before, I use more strands to be safe, but on my own bow designs, and string nocks I made, I know what they are capable of.

I just always like less mass in the moving parts too.  I like the smallest fletching I can get by with, the narrowest limbs, skinny 5/16" arrows, and thin strings.
Title: Re: Skinny Strings
Post by: Rob DiStefano on January 26, 2012, 01:46:00 PM
keep in mind that as long as a bowstring is well made, has sufficient strands for the bow's holding weight, is of a proper string material and build for the bow in question, nothing else matters.  that's where personal subjectivity enters the equation.  do whatever makes you happiest.
