Silencing a speed bow.
 

I shoot a 2008 82nd Airborne, but it sounds like a shotgun in the range. I'll admit that the range has bad acoustics, but it is by far the loudest bow in the place. I have just about every bowjax product on that thing. The only thing I have left to do is get MeanV2 to make my a string suppressor to replace the stock one. I need to make it quieter. Any suggestions.

RE: Silencing a speed bow.
 

Shoot a heavier arrow. Speed bows are loud(er) than bows that shoot a little slower... the more stored energy... the more wasted energy.... wasted energy is either noise, vibration or both... but it has to go somewhere.

The other possibility is that something is out of whack... which depending on how much you mess with your bow and your level of expertise is either exactly the problem or just a possiblity.

RE: Silencing a speed bow.
 

X2!!! Put that wasted energy to good use rather than blowing it off into the cosmos.

RE: Silencing a speed bow.
 

I mess with it a ton. I use it to test every product I recommend because I know that it will test the products to the max. Now, I think that something is out of whack because it was not this loud before, and all I did was add products that should silence it. I gave it the once over and did not notice anything. Got any ideas?

Also, to add credibility to my statement that something is wrong with the bow, there was a guy shooting a 360 fps x-force that was not as quiet at my 82nd before, but was silent compared to mine this time.

RE: Silencing a speed bow.
 

Something has come loose or one of those products messed with the harmonics and put them into some sort of resonance amplification (really reaching here:eek:). Try taking them off one at a time and see what happens.

RE: Silencing a speed bow.
 

The only things that I put on were those bowjax that go on the end of the stabilizer. Something else is wrong.

RE: Silencing a speed bow.
 

Try using cat whiskers....I heard that Bowtech actually put out a study showing that their silencers were the least effective and cat whiskers were the most effective.

RE: Silencing a speed bow.
 

I tried those whiskers and the thing that they do best is slow the bow down. Not worth it. I'd just get a heavier arrow that would penetrate better.

RE: Silencing a speed bow.
 

I need ideas of what to look for that might have come loose.

RE: Silencing a speed bow.
 

worked for my brother....but he shoots a diamond and it is not a real speed bow.

RE: Silencing a speed bow.
 

It did make it quieter, but I think that is because they also slow it down and, like I said, a heavier arrow would do the same thing.

RE: Silencing a speed bow.
 

Well it could be one of a couple of things stick...

First off.... is the noise a vibration noise or a smack/crack noise.

If its a vibration noise.... 90% chance its in the sight.... damn near ALWAYS the sight. Now, with an HHA... those odds drop a bit.... but guys shooting G5s.. Vipers... Tru Glos..... SIGHT.... ALWAYS! Occasionally on a Mathews it will be a loose grip (I'm going down the list here... I know you are working on bows now.... don't know how long you've been at it.... but you can spend a lot of time chasing your tail on stuff like this). BTs sometimes will have the set screws on the underside of the limbs pockets get a little loose too.

If you have a cracking noise.... then you got a whole different animal.

The first thing I would do is bottom the bow out to max poundage and back it off again to wherever you had/want it. Recheck the specs... make sure your cams aren't leaning... axels aren't bent... limbs aren't cracked. Look to see if a rest or something is smacking the riser somewhere. Make sure everything is lubed. Make sure everything is tight.

What kind of release are you shooting? Nothing like a Chappy Boss to make your bow sound three times as loud as it is....

RE: Silencing a speed bow.
 

With all the vibration dampening rubber on that bow, you can't feel a thing. It's great. So, I can say with confidence that it is not a vibration issue.

It is with out question, the loudest cracking sound I have ever heard a bow make and I have shot some noisy bows. My first thought was that I had a cracked limb, but that is not it. I know that it cannot be the rest because it is not only way too loud to be that, but every where the rest could hit is covered with felt for that very reason. I just took a closer look at the cams and there are no cracks. However, the bottom axle is way out of place and looks like it is about .5" to the outside of the limb. Not normal! The bottom cam is also off. No point in doing the poundage check because it is already maxed out at 73#. I don't have a press at my house yet, so I'll have to wait until tomorrow to put it back into place.

I shoot a Tru Fire Hurricane Glove release that works very well. I need something to grab onto because I was a longtime finger shooter and it just doesn't feel right to have all that weight on my wrist.

Any ideas as to how this might have happened???

RE: Silencing a speed bow.
 

No clue as to how it could have happened[:@]

my experience with noise and vibration is very good to say the least. my bt general was always doing something odd, + i was a tech. at an automotive dealership, so my earsand feel are keen. what i will do, isstart eliminating things one by one. start with your bolts and tighten everything down. everyone on the whole bow. then, by process of elimination, start removing stuff one at a time, testing to see if the noise is different after removing. it helps alot, andalot of times it will be something totally random. my string tamer caused me an hours grief one day on my general, b/c i thought there was no way that could be it.

sucks to hear that you axle is pushed out and cam is off! make sure you check the axle before you put it back together b/c shooting it while not positioned "could have" caused it to bend.

as far as quieting the speed bows down, the 82nd and 101st arent quiet at all imo. ive been around tons of airbornes even before i had mine and theywere all loud to me. i just got used to it. the make up for the stealth shot in speed is the way i look at it. if my arrow is projected at a deer at 300 fps, than im willing to bet he wont have time to move due to noise. i killed two deer withmy loud 101st this year, adn neither jumped the string and one wasfully alert. the way i see it is, in hunting speed and noise cancel eachother out at a certain point.

RE: Silencing a speed bow.
 

IDK, I wouldn't be suprised to see a deer jump my shot because I like to go for the longer shots (60 yards). It's more fun that way and I can actually see the arrow hit at longer distances.

I will probably take it to my proshop and have them ask BT about it. I hope it is under warranty because the piece that holds the axle in place (I don't know what it is called) on the one side is gone.

Also, I think that the stock string suppressor has something to do with it because it is quieter when I don't use it, but I get more vibration.

I'd bet THIS right here is your problem. I thought these things were the LOUDEST rests I've ever heard. Beyond that, YOU don't really want to do the things that would really help, so I don't see any need to waste my fingers energy on the rest of what WOULD work.

RE: Silencing a speed bow.
 

The heavy arrow thing just ain't gonna happen. I understand the reasoning behind it, but I like the speed too much.

RE: Silencing a speed bow.
 

I know, that's why I said I wouldn'twaste the space.........:D

You'll grow out of that when you decide you want to HUNT!!! ;)

RE: Silencing a speed bow.
 

Maybe. For now, I think it is more fun the way it is. Besides, I'm sure that I would have been successful if I put more time into scouting. I only saw one deer and he saw me first. As you know, a fast bow does not mean the the hunt will fail. It is the Indian not the arrow. I'm a pretty bad Indian.

RE: Silencing a speed bow.
 

Now, can someone give me some ideas as to how my axle got out of place. No more about me wanting to shoot fast. I'm not the only one. Please!

RE: Silencing a speed bow.
 

You're still young....

Try a different rest and see if it makes any difference. I HONESTLY thought the Limb-Driver Rests were LOUD, to say the least. Might add a little extra felt to the shelf where the rest hits, etc.

RE: Silencing a speed bow.
 

If your eclip came out on the axle somehow, that could have let your axle slip through. eclips also get loose and make noise so maybe that was where your noise that you first heard came from. Your cam bearing could have also wore out/broke somehow causing the friction from shooting to create noise, and further, bend/move your axle. These are all just theories of course but you have to start somewhere. It will be easier to tell once you know if anything is really damaged or not.
Derek

RE: Silencing a speed bow.
 

Doug-- Thanks, I'll try that. I'm always testing out new products. I am going to try to tie in my QAD HD and see if that is any better after I get my axle fixed.

Anyone know how that might have happened???

RE: Silencing a speed bow.
 

That's what they call those things. eclips. I'm going to the shop on Saturday. Thanks for the help.

RE: Silencing a speed bow.
 

My LD is by no means loud at all. I actually have foam under mine so there is no noise. I went from a WB to the LD and have had a nap QT4000 so I know what a loud or quiet rest sounds like. Maybe there are some loud Ld's but not mine. Im the only one I know personally with one so I cant say that there arent any.
Derek

RE: Silencing a speed bow.
 

I know that the LD makes noise, but no more than the bow when it is shooting like it is supposed to.

Drock-- take some pics of how you set that foam up. I'd like to see that.

RE: Silencing a speed bow.
 

Black,have you ever even looked at ballistics of an arrow.Compared slow arrows to fast arrow drop differences.


OR,do you just look at a chrony and pin gaps?

RE: Silencing a speed bow.
 

The second one.

I know that I will get more momentum and therefore better penetration with a heavier arrow.

I am always looking to learn something new, so please tell me what I should expect when shooting a heavier arrow. This would be very helpful because one of my favorite things to do is to shoot out at 100 yards. I want to go out further, but my HHA won't go down any further. If a heavier arrow drops less that might get me to switch to a heavier arrow.

RE: Silencing a speed bow.
 

Well,a heavier arrow will hold it's speed longer than the light arrow.That really isn't what I am talking about but the olympians use recurves at 90 meters.;)



I had a target bow that was slow by all accounts that I used for 3-d.I shot it at 260 fps,if I were to lighten up my arrow to get 280 fps.On a 40 yard shot,misjudged by 3 yards(37 yards) would impact 1/2" lower with the slow arrow verses the faster arrow.


Probably much closer than you would expect,now,equate that into hunting.Dead deer either way.

It might mean more on the 3-d course BUT,if you are misjudging by 3 yards,you aren't winning anyway.;) atleast not in open class.

RE: Silencing a speed bow.
 

After shooting at a certain distance, a heavier arrow would surpass a lighter arrow in distance traveled b/c the weight of the lighter arrow enables the air resistance to slow it down at a more rapid pace. The heavier arrow will continue to hold momentum, thus, it will continue to travel at a greater distance. So essentially at a distance of say...70-80 yds, an arrow with 30gr. moreweight, might actually have less drop for that ten yards than the lighter arrow.I could probably figureall of this out butI already have enough math to do everyday:D All of this is subjective to everything of course but physics says, what i explained is right;)

If shooting distance is your thing though, there is no need for anymore of our conviction for you to try and shoot a heavier arrow. Shooting targets is your thing, as mine, so you are more concerned with speed and trajectory 99% of the time. Hunting season though, i will have a totally different opinion b/c a small diameter heavy arrow will penetrate better. Thats all there is to it.
Hope your bow is easily repaired and back to normal soon,
Derek

RE: Silencing a speed bow.
 

I knew that the heavier arrow would keep it's speed longer, but what I am interested in finding out is at what distance the lighter arrow has actually fallen more than a heavy arrow. I'll slap a 500 grain fatty together and see what happens at 50, 60 70, 80, 90, and 100 yards. If it is higher, I will be switching. Based upon my findings, I may or may not switch. As a science guy, this is kinda my thing. I just have never tried it. I will probably shoot my light arrows for 3D because it is a little more forgiving if I misjudge distance. At least on the shots less than 40 yards, which is most of them.

RE: Silencing a speed bow.
 

If a recurve can go 90, then an 82nd should be able to do a lot more than 100. I'd like to get out to 120, and if a heavier arrow will get me there, then I am all for it. I'll just need someone with OT2 to help me find one that is spined correctly. I have a mac, so I can't get it.

RE: Silencing a speed bow.
 

Science is my thing as well to say the least. Engineering here! I think the arrow weights will have to be relatively close for you to have a usable outcome b/c if you put a 500gr. arrow on vs your 360ish the effect of the heavier wouldnt come into play untila much further distance.

RE: Silencing a speed bow.
 

Biology for me.

Ok, a 400 grain arrow. I need to have some one with OT2 spine me for that. Which shaft?

RE: Silencing a speed bow.
 

Re: Why the E Clip came off.....

The reason your eclip came off is the same reason your bow is loud.... your arrow is probably too light. If your axel was sticking out an extra .5" from your limb... it may not have been in the limb at all.... which probably means that your axel is bent... bearings are shot..... cam is bent.... or all three. Infact, I'm kinda suprised it didn't break the limb or just blow up in your face all together.

Vibration will do terrible things to a bow man. It should be covered under warranty.... make sure you take the cam out and lay it on a flat surface and check it over to make sure its still straight... otherwise your bow will NEVER shoot right. Roll the axel too.

RE: Silencing a speed bow.
 

Will do.

My arrow is more than 5 gpp, so why is that too light? If I need to shoot a heavier arrow, BT should have told me that. They say 5 gpp and I shoot 5.027 - 5.062 gpp. I understand that it is close, but... dang it. I was planning to own at techno hunt this weekend. That won't be happening.

RE: Silencing a speed bow.
 

My 70 lb Black Ice is shooting in the 280s with a 419 gr arrow and is shooting really quit. The string rubber broke off and the doesn't make any more nose that it did beforewhen they were on.If your bow that nosy I would say you have some thing loose are a bow really out of tune. Heaver arrows is every ones answer and is not always the right answer.

RE: Silencing a speed bow.
 

What is your arrow weight?

Think about it like this.... 5gpp is the gold standard.... its the same pretty much for your soft shooting Parkers and Fred Bears as it is for you super hard draw wrist rockets like your 82nd. Which one do you think is storing more energy and has more vibration?????

See... my HCA Iron Mace is warrantied down to 3.5gpp..... you don't know nothing about speed black stick....;).....try 370s on for size..... and she is still covered under warranty.

RE: Silencing a speed bow.
 

367-369.5 grains. I always weigh all my arrows. I am considering using wraps and 5" feathers instead of 4" feathers to both give the arrow more weight and help stabilize it at longer distances.

I know that there is a lot more vibration in a super bow than smooth bow. They have a lot more KE and like you said, that energy has to go somewhere and unfortunately not all of it makes it to the arrow.[:@]

I've shot 370 out of a super-tuned x-force at IBO specs. I just thought that was way to much speed. Speed is cool to a certain point. I have to admit that those Barnsdale limbs are pretty impressive, but I still like the feel of my 82nd the best. My 82nd is right where I like it and that is why I bought it. I know speed, and I know what I like.

What I would like to see is a super-tuned HCA Speed Pro with a 3.5 gpp arrow. That would be impressive. Maybe 380???

RE: Silencing a speed bow.
 

take a picture of the backside of your cams. just a threory after looking at mine and making a few adjustments.
