Title: I can't quiet my Dorado!!
Post by: INstickbowguy on November 26, 2012, 02:52:00 AM
Ok ive tried everything. May be the nature of the beast. I have a 44# Dorado @ 28" with medium wood/glass ilf limbs. I have homemade wool silencers and wool string ends. 450 gr 35/55 arrows tuned perfectly. Bow seems to perforn best with a brace of 6 7/8, I get the least noise and vibration. It does not like anything over 7". I find this weird because everyone ive seen shoots the bow with a 8" +  BH. Im shooting an Oliver D10 string..not sure of strand count. I also have felt inbetween riser and limbs. Tried adjusting silencer position.... its a lot quiter than it was ..but still getting some vibration and not a clean sound at release. Any ideas???

Wax very well your bowstring.
Try an heavy arrow.

Might try a stiffer spined arrow. You can then add some weight to the front end to break the spine down. Heavy arrows tend to require more brace height and they are usually quieter. Just an idea.

With your BH that low, you'll probably never get it quiet, too much string/limb contact. Why is your BH so low? IMHO, a few fps performance aren't worth all the noise and trouble.  My two 62 inch ILF bows have BH's of 8 inches, my 64 inch ILF bow has BH of 8 1/4 inches.  All are dead quiet with only a couple wool/acrylic puffs.
My advice, set your BH at 7 3/4-8 inches and see how it shoots, I bet it quiets down and will still shoot good for you, plenty fast too.

I'm sure I don't have a good answer for you but some individual bows may be affected by a change in string material.You might try experimenting with that.You may have already but I would also take a hard look at tiller and maybe experiment with that.Maybe start with even tiller and work up.See what the bow likes.Good luck with it.

What kind of sound is it making?  Klack (arrow), Snap (limbs), Twang (string) or Pow (ultra low-stretch string)?

Trouble is, it's a trade-off.  Most things you do to quiet a bow will effect performance.  But a quiet bow is worth it.  A one-piece bow is usually easier to quiet down.

Wool puffs 1/4 of the way down the strings are great.  I trim mine to 2" and make sure they are good and full.  Start with a bundle of 20 strands of 4" long yarn pieces.  Then pluck the string a few inches several times and trim into balls.

You won't like it, but a Flemish tied B-50 or B-55 string is the quietest (IMHO).  

Increase brace height.  S/B 1/8th of AMO length to start.

What is your rest?  A rounded shelf with a fur rug (seal if you can get it) I find to be very quiet.  Also make sure the nock point is at the proper height over perpendicular to the rest.

Heavy arrows (wood & glue on points are usually quiet).

My bow is louder and vibrates more with a brace over 7". The sound is more of a vibration sound ....like sonething is loose. I checked everything though.

I watched a utube video of a gal shooting a Dorado hers was very noisy. I would try a B50 string like stumpkiller suggests. If that does not work or if you don't like that try a SBD 6 strand string with their wool silencers, you may need a heavier arrow-perhaps you could cut a little off your current arrows and increase weight with heavier inserts and points. The suggested BH is 7-8" have you tried going all the way up? What makes you think your current arrows are perfectly tuned? Just a question-no disrespect.   :archer:

I tried 7" -8.5"....loud. I bare shaft tuned these arrows

Check the knock fit. If it is too tight that may cause a problem. Also on one of the MBB videos Ken Beck explains tuning. He says that sometimes a shooter puts too much downward pressure on the arrow when shooting split finger unkowingly. Long story short he recommends a elevated rest.

Recommmended brace height from Hoyt is 7"-8".

Ditch the wool felt between the limbs and riser.  Get yourself a bicycle inner tube and cut a section to fit the same area.  The inner tube pad,catwiskers,a BH of 8", and an arrow of around 9-10gpp make my dorado VERY quiet.

Cat whiskers better than yarn puffs?

X2 on all this, plus I use a skinny string it might help....

Depend the string material,cat whiskers work with D97 and D10 but totaly inefficiency with astroflight material,only natural wool work well with this one.

Having worked for a Hoyt dealer for 3 years I would start your brace height at 7.75'' and work up from there. IT may even be as high as 8.25-8.5''.. Just my past experience. Good luck finding what works for you.

also mole skin under the limb pockets and cat whiskers (2 on bottom, 1 on top) worked very very well.

I replaced my factory string with a skinny string and it made a world of difference.

For pure silencing wool is much better than cat whiskers. Cat whiskers only real advantage is they are relatively inexpensive and won't hold scent or water but in my experience wool is the best. I don't like fur silencers at all.

I chased obnoxious noise on my first home brew recurve for the first three months after building it. I hung more crap off the limbs than a Christmas tree. And in all that time, I ignored peoples advice about nock fit. Actually, I didn't ignore direct advice, just comments found via the search function. One day I decided to try my hand at twisting a flemish string. So, I ordered the materials, built a jig from specs found on this site, and took a guess at strand count.

My first thought was, "oh crap, my nocks are way too loose.". But, I figured I might as well try shooting it. To my surprise, the bow was dead quiet.

Remembering the notations about nock fit I set out to determine if the difference was the superior quality of my first string, or nock fit. I loosened one nock substantially and tried it on my old string. Sure enough, dead quiet...

I have now removed all of the limb ornaments and it is still dead quiet.  So, I would try a looser nock    :)  

Coming from compound shooting, this revalation was a BIG surprise to me.

Lots of good advice here....dang that brace height seems low.

Divide your string length by 3....put one silencer at 1/3, and one at 2/3.

I have been playing with homemade silencers that are part wool yarn, part cat whisker. I had a troublesome recurve that this method "fixed".

Not to get off topic, but a thing or two to note about silencers...especially cat whiskers.

WHERE you install them matters--and silencers can be tuned, just like brace height.  Some bows don't follow the "rules", so you may have to tinker to find the "sweet spot".  I saw one bow where the silencers worked best about 5" or 6" from the ends--doesn't make sense, but that did the trick.

HOW you install them matters.  I tie mine on around the string so they can be moved up or down for tuning.

Along with this, one big mistake I've seen with cat whiskers is leaving them way too long.  More is not always better.  Leave them too long, they will make their own slapping noise.  Fold the silencer in half and put it on.  You'll have 1/2 the length but it will be twice as thick--then trim it down so it makes a little ball.

I haven't run across a bow yet that I couldn't quieten (pending there wasn't something inherently wrong with tiller, etc.).  Cat whiskers, but properly installed, work as well or better than anything I've used.  Took me a while to figure out that how and where they were applied made the difference.

I put a skinny string on mine and it eliminated all vibration!!!   Dead quiet!!
