How quiet can I expect an ILF bow to be? I have been shooting longbows mostly for years and I think I got used to them being almost silent with a heavy arrow. I recently got a Samick 17 in. machined aluminum riser with long carbon and wood limbs. I moved the brace height around from 7 3/4 to 8 1/2 and it's not really loud but noticeable. I padded the string groove and put a little Velcro in the limb pocket. Is it just the nature of ILF to hum on release or should I try limbsavers? Thanks
It's a new bow from Samick called a Discovery. 17 in. aluminum riser, 45@28 long limbs carbon and wood. I am using NAP center rest and I draw 29.5 in. Arrow flight is good with 400 Axis Full Metal Jacket and 125 gr. point and 2 in. Vanes cut 31 3/4 bop.Bare shafts group with fletched. The bow didn't come with a manual. The only tuning I did was brace height. May be hum was the wrong word. I will try the limb bolts. Thanks
Oldbowyer hit the nail on the head. Everytime i shoot my recurve limbs i shake my head and go back to my longbow limbs. Guess im just a ilf longbow guy these days. My recurve was quite, but my longbow limbs are silent.
I screwed the limb bolts in 3 turns and that seemed to help. The draw weight went up 4 lb. so I'll have to tune the arrows again. I suppose if I want to shoot a recurve I'll have to get used to some noise. Thanks to all.
If your a hunter you might want to look at Lancaster wood/glass limbs. I've been finding that if there is carbon in the limbs there is that hum you described, its a unique sound to my ears that comes from a carbon limb. I put limbsavers on all my ILF limbs and they do help. I also end up on the high end of the brace height. I dont think its one thing that makes em quiet but a combination of things. Even silencer placement can effect things. I shot with a buddy a couple weeks ago who shot a Titan III with wood/glass limbs and couldnt get over how quiet it was.
I've had good luck with limb savers, farther out from the fades the better. Good hardware helps too!!! Dryad makes a machined brass piece that screws onto the limb bolt, can't remember what that piece is called, but it's tolerances are a lot tighter, so it doesn't vibrate on the shot like a lot of the cheaper ones do! But don't expect it to be as quiet as your longbows. I played with the ilf for a while and still own a couple, but basically just use them for loaner and lesson bows. I think they really shine if you're going to string walk etc, but if you're just going to shoot them split and standard tiller, why bother!
Even full length, I have a hard time believing that 400s tune from a 45# bow. If turning the limb bolts in helped, that supports my theory. And when I said something is loose, that meant anything that can be tightened has to be checked.
In my experience, you can expect them to be as quiet as any other TD recurve.
Your question intrigued me to the point where I decided to do a little experiment on this rainy Saturday morning.
In the first video, I am shooting a vintage 1968 one piece Bear Grizzly, 46# @ 28", Dacron string w/cat whiskers and brush buttons. The arrow is a Beman ICS Bowhunter 500, cut to 29" with a 125 grain tip. (365 grains total weight, about 8gpp)
My daughter is holding the camera literally 3 feet from the bow. If you listen, you can easily hear me clicking the nock on the string. Sorry about the TV, we forgot to turn it off for this video. :)
In this video I am shooting a TradTech Titan riser with Uukha XO Evo2 limbs, 42# @ 28", fast flight string with yarn puffs and yarn wrapped around the string loop ends, Limbsavers on limbs. There is no silencing material in or around the limb bolt or ILF connection. Same arrows. (about 8.5 gpp)
Your opinion may differ but to my almost 57 year old ears, there's not a lot of difference.
The experiment would have been better if we weren't so close to the target where you hear the impact of the arrow, but you get what you get.
Viper : At the previous settings the 400 shaft at 31.75 bare shaft was nock end left a little in flight but grouped with vane shafts (right hand shot). I have my Center Rest all the way in against the riser. If I hold the bow at arms length and sight down the string the shafts tip is just a hair to the outside. With the limb bolts turned in I'm now drawing 54.5 at 29.5. so I'll see what happens with the shaft. BTW fast flight string. Love your book!
OK, at 54#, with an arrow that long, your getting in a better neighborhood, spine wise.
Just for giggles, since sound is an issue, if you have a Dacron string, I'd give it a go. At 20 yards you won't notice much of change in flight with fletched arrows, but yes, bare shafts will act weak.
My Jennings Black Lightning warfed (ILF) riser with TradTech 2.0 wood/glass limbs, 44#, shooting a FF Plus string with one set of cat whiskers, shooting a 9.7 gpp arrow, is the quietest recurve I've ever owned or shot. I set the brace at just where the string lifts off the very ends of the string grooves of the limbs while strung. Amazingly quiet. And excellent speed/cast too.
Rattles and buzzes are usually caused by loose screws on metal ILF bows. I normally wrap plumbers tape on bolts or use the light thread sealant on small screws.
Some limbs perform and sound best at a certain preload or tiller. I have a set of limbs that buzzes when set at max preload, no buzz two turns out. For a competition bow the buzz doesn't matter but for hunting it can. Tuning ILF adds the variable of fine- tuning the limbs as well as the arrows. I tune the bow first, arrows second.
And arrow spine can be very individual, especially with different limbs. I shoot 31" .400 spine with 120 gr. tips and my rig is about 41-42# at 27". Another ILF setup I own, same draw weight shoots a 30" .600 spine with the same tips.
But, when tuned well an ILF bow should be quiet and well behaved. Probably won't be as quiet as a long bow (What recurve actually is?) but quiet enough for hunting.
I've had the same issue with most recurves compared to my Longbows. I've got two ILF set ups now and one is whisper quiet and the other had quite a hum. I had padded both limb pockets, both were carbon TT limbs, but my quiet one had a set of limb-savers on. I bought a second set and now I have two Whisper quiet ILF bows. They work really well on recurves , just a couple inches above the fade-outs.
