Title: Tired of replacing wood bows!
Post by: botech on December 15, 2010, 10:16:00 AM
This past fall I buried my 4th bow in three years.
Rather than wondering why and finding few good answers, I have decided (if possible) to just look for a non-wood model.
I am at a loss as to where to look though.
Any suggestions?.

I would add Hoyt Excel to the above mentioned.

What is your preferred overall bow length?

What is your draw length?

Can you tell me exacly what you mean by 'buried'?

Are you breaking bows?...if so, are these bows you have made or someone elses?

Remind me not to offer you a loaner...lol

I'm curious as to the kind of wood bows that are breaking on you?

I'm not asking the bowyers names but the kind of wood that makes up the bow.

Are they self bows? laminated? any glass in the bows?

"Inquiring minds want to know!"....lol

Thanks in advance!
God bless,Mudd

I agree with ferret.I've built bows for 20 years and have many and sold and built for fiends bows that are shot 10;s of thousands of times and are some have been in use hunting for years.
I personaly am shooting a 60"s 56 #'s @26"s that I build 2 for a guy and his wife and he only took his.Her bow was hideing in my bow shop for 12 years in 06 I had 2 strokes and had to go down from 61#'s.I dug it out And I'VE SHOT AND HUNTED WITH IT SENCE 07.
  Not wanting to step on anyones toe's but it sounds like your bows wer'nt built and tillered to well.

26" inch.
I am looking for a bow with no wood in it at all.
Not that this isnt a heavy enough order, I really want to try and stay around 54-56" and have 70#

first was a mamba that blew the top limb.
Next was a bear 48Mag that blew the top limb.
Next was a mamba that split the top and bottom limb and last was a 48Mag that blew apart...de-laminated totally.
(Bear said that the 14 month bow was out of warranty and left it at that!)
All bows shooting alaskan shafts with 250 grain heads.

All my bows have 2 sets of beaver balls and double nocks attached.
all bows are shot 10grn.+
I generally dont walk the string but have on occasion.
I have use Dacron (15 strand) on two bows and Flemish (18) on the other two.
One bow (most recent blow up) was used in a few heavy rains but there was no openings in the finish...until it opened itself up.

Yes, 10,000 and maybe more but I really dont see that being too many.   :confused:  

I store everything in about 40-45% humidity in a home that is forced air.
I have wall hangers for all my bows that allow the bow to be stored horizonally.
I unstring my bows daily after shooting and I rarely ever do this without a stringer.
I have had bows blow that I have only used stringers on and others where I have used my body as the brace.
That said...I have never failed a bow in short order after self bracing to string it.

70# 10,000 shots..maybe more if you're talking with each bow. I guess that's only 27 shots a day for a year.
Dang..
You must have arms of steel.

After blowing out three bows and having the mamba no longer offered in 70#...I was very careful not to over shoot the last one.
I can easily shoot over 70# (follow H.H. approach) but I cant find any recurve bow that I will trust anymore when it can be made that heavy.
I am really depressed on this last point   :(

I had thought that Black Swan made a total graphite bow but I dont see anything devoid of wood on the site.
I really would rather have a wood riser but the wood in the limbs just has to go...if I can find the perfect combo

I am currently shooting a 2 bear bows.  one is from 1972 and I have killed 2 deer with it and the other is a new one that has one deer.  I have only been shooting bows for 2 years so I practice a lot and I mean a lot...in early season I was shoot 100 to 200 arrows atleast twice a week and now I normally shoot around 50 arrows twice a week... Sometimes less sometimes more.  I really like to shoot so I really have to make myself stop shooting...

Anyway I did not mean to ramble on, but I am hard on my equipment and I have to say my bows shoot like they are brand new.  Both of my bows are 52"  

with a 26 inch draw length I would think you can draw any bow on the markey without blowing them
up.

How do you keep having to replace bows?  

Oh Oh I got it!!!!!! You replace the bows because when you miss a deer you slam them against the tree or ground...I would recommend not doing that!!!!!
Title: Re: Tired of replacing wood bows!
Post by: vermonster13 on December 15, 2010, 01:58:00 PM
Black swan takedowns have no wood in them unless ordered that way. Aluminum riser, carbon and foam core limbs with phenolic wedges.
Title: Re: Tired of replacing wood bows!
Post by: Zradix on December 15, 2010, 02:01:00 PM
Aren't there a lot of bowyers that'll make a carbon/foam/carbon limb.
Morisson, shrew, trad tech to name a few I THINK do.

I'd be worried you'd run in to the same problem though.
Title: Re: Tired of replacing wood bows!
Post by: thewal2 on December 15, 2010, 02:02:00 PM
Hey,

Question...could it be that he had 2 bows that were 48amo that blew up because short bows cant handle that much poundage?  

I have heard of the mag48 blowing up on 29 inch draws but a 26?  Weird...maybe you are measuring your draw length from the wrong place?  an arrow rest in 2.3 to 3 inches long if you measured from the back and not the front you would lose 3 inches... 29 inch draw on a mag48 blowing up makes more sence.

Maybe I am wrong I dont know...?????
Title: Re: Tired of replacing wood bows!
Post by: chanumpa on December 15, 2010, 02:12:00 PM
My first idea after reading all of this was bows are too short for your draw length.I too am surprized that they did that as yours is only26".Back to the grindstone I guess.Youll find one that willnot blow up on you.Especially,if you go to a lil; longer bow.Best of luck.
Title: Re: Tired of replacing wood bows!
Post by: Don Stokes on December 15, 2010, 02:13:00 PM
I asked about three under because that changes the stresses on the limbs, and the effect would be magnified on those short bows. I recommend you go longer if you want to keep shooting that way.

I don't think wood is the problem.

How many winners have you had out of your last 5 lottery tickets?  If you say "0" then I would chalk it up to bad luck!

I hope you figure it out and good luck with your new bow.
Title: Re: Tired of replacing wood bows!
Post by: bornagainbowhunter on December 15, 2010, 02:51:00 PM
I shoot longer bows, but draw 29".  I can't imagine the weight being a problem, I shoot 67#@28" so I am pulling about 70#.  27 arrows a day is not very many really.  Even if you only shoot 3 or 4 times a week that is 75 to 100 shots a session.  

Not sure what the problem is, but I know I sure don't want any of it.   :dunno:

If you are breaking laminated wood bows, you are doing something seriously wrong.  There are laminated wood bows seeing daily service that are pushing 60 years old.

I'm not taking shots at you, just pointing out that the wood isn't the problem, and leaving wood behind probably isn't going to fix the issue.
Title: Re: Tired of replacing wood bows!
Post by: TDHunter on December 15, 2010, 04:17:00 PM
Most of those (ie mamba) are production bows and aren't the quality of most custom bows. I watched my brother blow up a mamba as well. Try a good quality custom bow it will last longer then graphite. I've put 10's of thousands of rounds through my checkmate recurve and they keep going. I've shot my go-to checkmate for over 15 years, and Ishoot all spring, summer and fall and a bit in the winter.
Title: Re: Tired of replacing wood bows!
Post by: Jeff Strubberg on December 15, 2010, 04:22:00 PM
I bet there are Bear production recurves out there with a million arrows or more through them.

This is either phenomenally bad luck or something odd being done to these bows.  To have one break in a lifetime of shooting is bad luck.  Four is just unheard of.

I may be completely wrong but, if you are shooting that much and unstringing your bow daily, I could see where that would be putting stress on the limb tips. I think if you are shooting daily, maybe it would be better to leave the bow strung.  :dunno:
Title: Re: Tired of replacing wood bows!
Post by: Benny Nganabbarru on December 15, 2010, 05:56:00 PM
Yeah, the weight of those recurves is definitely not an issue. Many blokes shoot heavy recurves without a problem. I even dry-fired mine once, and it is fine.
Title: Re: Tired of replacing wood bows!
Post by: hunt it on December 15, 2010, 06:13:00 PM
I'm with two arrows, if your stringing and unstringing daily that is alot of extra stress. Most of my bows up to 80# never get unstrung unless I'm flying someplace.
Title: Re: Tired of replacing wood bows!
Post by: Cyclic-Rivers on December 15, 2010, 06:13:00 PM
I dont know what the problem might be but I do think there is a striking coincidence that the bows all seem to break on the upper limb.

Suggestion; find the source of the problem. Wood bows are as beautiful as utilitarian. Breaking bows doesn't happen without some effort or misuse. Not to say you're misusing your equipment; but, a well made bow should pass a quarter million (+/-) arrows minimum before faltering.

I agree leave them strung up if your shooting daily. But something or someone is causing them to blow up man! I've had strings on old bear bows break and friends dry fire them and they are still shooting fine. Makes you wonder though with that kind of bad luck. I would find someone close, archery range,pro shooter,  that has shot alot and have them watch you shoot and look at your equipment and see if anything sticks out to them, you might just be overlooking something. Good Luck.( Post a U-Tube video of your shooting for all to view ) !!

I leave my shooters strung all the time. I called the Widow folks about this (only one of mine is a widow) and they've left bows strung for more than 20 years with zero impact on the bow. Stringing and unstringing event with a bowstringer (the only way) is far more risky than leaving the bow strung.

If I thought I could only shoot my recurves 27 times per day -- I'd run from traditional equipment as fast as I could (with great regret) and call up the fellow who bought my compound.  I can't imagine it matters at all, within a person's physical limits, how many times they shoot these bows.
Title: Re: Tired of replacing wood bows!
Post by: Orion on December 16, 2010, 10:16:00 AM
I've been stringing and unstringing my bow(s) almost daily for nearly 50 years.  Haven't had one break yet.

Botech:  Were the limbs on your bows beat up to start, perhaps some split glass, good size dents in the edges, etc?  That sort of thing can lead to breakage relatively quickly.
Title: Re: Tired of replacing wood bows!
Post by: Hookeye on December 16, 2010, 02:05:00 PM
Orion: using a stringer correctly and using a stringer can be very different things  ;)  

Also, some stringers may be more error prone in usage than others.

I like tip to tip types, but once my strings get shot in I pretty much leave my bows strung all the time.

Whether the bow is filled with foam or wood it will break-or not. This has nothing to do with the 'filler' there is something else going on. IMO

Botech...

Is there a vent pretty close to where you keep your top limb tips in the rack?

Just grabbing straws here...maybe a chem room? cleaning solutions that may be venting. Or maybe pool chems...?

Could be he is twisting the bow when he draws, either right hand or left, will the throw the bow off track.  The only thing that would cause this, other than physical pressure, would be exposure to extreme temps.  I have bows that have been in use for 60 years and have only had one break and that was another person twisting on it.  This fellow needs a reverse handled Howard Hill Tembo or Big Five, with a straight grip, 64" to more than match his 26" draw, and pay close attention to getting the bow into the hand without torquing and make certain that the release fingers are equal pressure on the string during the straight back part of the draw with a split finger standard draw.  He says he is trying to use Hill form, it works best with a Hill bow.  i have been known to torque up a grip on recurves shooting Hill style to the point of lifting the arrow off the shelf.

Chris I have a 60# set of limbs on my Gamemaster2 you can have that bow for a while.......if you happen to blow up those limbs I have another set, so no worries! It's 58" long

I have never been able to figure out why your bows blow up, you always have plenty of weight for arrows and I've never noticed any torque when you shoot. i was thinking that maybe the nocks don't fit right? I have no idea.....

Question...could it be that he had 2 bows that were 48amo that blew up because short bows cant handle that much poundage?  

I have heard of the mag48 blowing up on 29 inch draws but a 26?  Weird...maybe you are measuring your draw length from the wrong place?  an arrow rest in 2.3 to 3 inches long if you measured from the back and not the front you would lose 3 inches... 29 inch draw on a mag48 blowing up makes more sence.

Maybe I am wrong I dont know...?????
Thanks for thinking it through like that but no...I am a true 26"

If I thought I could only shoot my recurves 27 times per day -- I'd run from traditional equipment as fast as I could (with great regret) and call up the fellow who bought my compound.  I can't imagine it matters at all, within a person's physical limits, how many times they shoot these bows.
This is a helpful bit of information for me and I believe that I will (in the future) leave them strung

Hey lads, I must strongly disagree with some of you here, regarding the daily unstringing of bows being a cause of limb failure. I always unstring my bows after each use, and haven't had a problem. Using a good stringer correctly, I do not believe that unstringing regularly can present a problem.

There may well be a scientific reason why your bows are dying, and I hope the puzzle gets solved.

However remote the probabilities, you may just be experiencing exceptionally poor luck.

I'd be interested to see how a Hill or Black Widow (or similar) would fare for you. Although not indestructable, they are quite tough.

Maybe you can find someone who can make you an Osage bow 66" to 68" in your weight range backed with bamboo or sinew.

The size of a piece of hedge that would be needed to build such a bow could be used as a pry pole for moving boulders.

I'm not saying it can't or won't break but if I were a betting man, I'd put my money on the "sage"..lol

Good luck with your future bows.

Post by: wulf on December 18, 2010, 01:18:00 AM
I'm no novice but in the last 25 years I've had 3 custom bows "blow" their top limb at the fadeout.  The first, a 60 inch recurve, was replaced as it was only a week old.  The second, a 62 inch recurve made by another bowyer from the same state broke in exactly the same place but only after thousands of shots. These two bows broke many years ago.  

My draw length is 29 inches, I shoot split finger and I've always used arrows in the 10 gpp range or heavier.  This past summer the third bow I had blow was a hybrid longbow 58 inches long and it too was a top limb at the fadeout that gave way.  By the way these bows all pulled about 55 to 60 pounds at my draw length.  I stored them unstrung, and in what would be considered a normal atmosphere for inside the home.

Although it wasn't 4 bows in 3 years it was enough to make me wonder if that was real unlucky or par for the course considering how much I shoot my bows.  

By the way not all bow stringers are alike either.  I always use a stringer that utilizes the limb tips to string the bow.  That type utilizes the entire working limb to string as opposed to those types that set a pad on the back of the limb which forces that limb to bend unevenly and in my opinion too much to string the bow.  I wouldn't use that kind of stringer.

Post by: 684Kevin on December 18, 2010, 08:57:00 AM
Just a thought here, not sure if matters. Could preloading the limb tips/limbs from twisting the string too much resulting in "too long" of a brace height cause the limb tips and the fadeout be stressed?  I've lengthened my brace to quiet/stop vibration in recurve bows but have noticed there is a big difference in how the limb tips react after the shot.  On a short brace height, the limb tips move back and forth resulting in typically a louder/more felt vibration recurve bow.  This movement of the recurve tips after the shot seems to give the bow some give/cusion from the result of the bows energy being released.  On another extreme, a real long brace height results in the limb tips stopping their after shot movement immediately or very soon after the shot.  Could this abrupt stopping of limb tips/limb cause undue stress on the limbs/limbs laminations?  Not saying this is what is happening here but I'm with many others on this 8/9 page post that there is something causing these limbs to fail and it seems to me that they are all failing in the working area of the recurve limb/limb tip.  I shoot both recurves and longbows. The longbows vibrations and limb tip oscillations don't seem to be affected as much by changes in brace as do my recurves.

I recently picked up a recurve made in England, A Marksan TS4. The bow was made in the early 70's and it literally is in brand new condition. The white glass is in amazing condition, not yellowing at all. When I first saw it I thought someone was remaking Hoyt recurves. So it proves to me, if the bow is made well, it will last.

G'day Botech
Got a note from Don, Don't know if I can help. Having broken many bows does not necessarily equate to being any wiser as to why, tho the experience does set u on a path of satisfaction in knowledge, as now one deems to have rectified the problem.
I appreciate u'r situation may appear exasperating as u want to definitively know why but there r probably always a combination of factors at work.  Murphy has a lot to answer.
I found the following to be true. None would intentionally steer u wrong and tho many have fine experiences with particular bows, so will obviously recommend them to u in the hope u may distinguish similar experience. It may not be the case in the heavyweight version.
Regardless of the best intentions of what others perceive shoulda, coulda, woulda and what works for them on the matter, does not make it so in anothers reality. On reflexion u are probably not doing anything much wrong and misuse is subjective. Yet again there are some base principles bought out already that obviously apply and u have made the logical reduction in checks. Here's that thread from when my breaks became intolerable. U might gleam some from it.
    http://tradgang.com/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=1;t=087740;p=3    

However I do not imagine u will find finer bows than the laminated wood n boo ones out there so perhaps in retrospect an time u may reconsider relinquishing sound trad values of a well tuned natural instrument of pursuit in the unsatisfying hope of better alternatives. I try only to raise some lateral awareness in hope.

It appears u are likewise hard on bows, so u might be relieved to know I can't kill the ones I use now having tried since, happily in vain. From that run of breaks I gleamed much from a couple PM's sent me from some willing wise with regards durable heavy weights and quality of craftsmanship and materials used. I have acquired a couple of proof recurves and was thankfully provided with a longbow proper and find preference now in these. A real learning curve and acquired delight in progress made more so as that gentleman has maintained some consideration in dragging me through despite some ignorance.
So too perhaps some bowyers are still learning and antithetical issues are compounded somewhat in heavy weights. Even though it's a series of lams an glass there are many factors that must be got just right in the process, everyone has an off day, mixed batch of resin etc.. U might be an unwitting recipient.

Have u tried a little longer bows? R all the faults with the top tips/fade always breaking down or top limb invariably?
I found a longer bow to be comparatively conducive to 70# weight. Then again @ 26"draw would ya reckon otherwise?
I did find that less than a 70# bow, for me at least, was a somewhat futile exercise within particular  feel & function processes and believe this may have been a criteria to failure in lesser ones but as to the heavier ones of good report I'm still a bit miffed and again I find difficulty in reconciling them. Indeed they were not on my end list of durables. A new set of limbs requires accessing for one broke bow, tho the limb length reckoned to be the problem, has been repeated in this remake!

How many shots are u putting through these limbs/session and is there a period of this when u fire in quick succession?
I still off 80+ odd shots/session approx average 4 days/wk and it may be the bows that broke did not like the quickness of succession that was sometimes applied in the latter stages of longer sessions. Energy = Heat etc. Is integrity loss compounded to existing condition?
How long are u holding u'r draw for?
A thought was, perhaps I sometimes held the draw too long, both as an exercise an discipline in fatigue after many shots, 150+, consequently this combined with the previous mentioned rapid shooting may have been an issue. Still my present bows remain unaffected by this activity but on advice I believe now the cast of the arrow may be altered, thus more consideration is given to smooth draw anchor and release.
Hysteresis = lag in effect, the delayed response by a object to the changes in the forces acting upon it. One can imagine how the fibers in the limbs under torsion might be affected by holding the draw longer, the instant springy recoil must be distorted some by holding fibers at stress longer. I had wondered about this but did not know there was a name for it.

I tried 3 under but also found this untenable in heavier weights and no use, for my part, on a longbow. Perhaps this is not so for u & others but It wasn't my cup a tea. The stress a fore mentioned by Don merits if it's the same break.
De-stringing & stringing may not cause any problems as care is taken with seating in the string grooves. I note from recent contributors, emphasis on proper stringer. In our high humidity I will not leave a bow strung if it is not being used within 7 days. Just a precaution.
Then of course **** happens sometimes.
The thoughts expressed here are my own imperfect opinion drawn from limited comparable experience than most, except perhaps in breaking bows and am happy to be corrected by views of wiser and voice of more experienced reason.
Along with everyone else an unlike the stones, I hope u get some satisfaction.

Indeed they were not on my end list of durables. A new set of limbs requires accessing for one broke bow, tho the limb length reckoned to be the problem, has been repeated in this remake!

How many shots are u putting through these limbs/session and is there a period of this when u fire in quick succession?
I still off 80+ odd shots/session approx average 4 days/wk and it may be the bows that broke did not like the quickness of succession that was sometimes applied in the latter stages of longer sessions. Energy = Heat etc. Is integrity loss compounded to existing condition?
How long are u holding u'r draw for?
A thought was, perhaps I sometimes held the draw too long, both as an exercise an discipline in fatigue after many shots, 150+, consequently this combined with the previous mentioned rapid shooting may have been an issue. Still my present bows remain unaffected by this activity but on advice I believe now the cast of the arrow may be altered, thus more consideration is given to smooth draw anchor and release.
Hysteresis = lag in effect, the delayed response by a object to the changes in the forces acting upon it. One can imagine how the fibers in the limbs under torsion might be affected by holding the draw longer, the instant springy recoil must be distorted some by holding fibers at stress longer. I had wondered about this but did not know there was a name for it.

I tried 3 under but also found this untenable in heavier weights and no use, for my part, on a longbow. Perhaps this is not so for u & others but It wasn't my cup a tea. The stress a fore mentioned by Don merits if it's the same break.
De-stringing & stringing may not cause any problems as care is taken with seating in the string grooves. I note from recent contributors, emphasis on proper stringer. In our high humidity I will not leave a bow strung if it is not being used within 7 days. Just a precaution.
Then of course **** happens sometimes.
The thoughts expressed here are my own imperfect opinion drawn from limited comparable experience than most, except perhaps in breaking bows and am happy to be corrected by views of wiser and voice of more experienced reason.
Along with everyone else an unlike the stones, I hope u get some satisfaction.

"unlike the stones, I hope u get some satisfaction." That one took me a minute...   :)
