limb tillering for sound

[harry 62]

60" rd longbow glass 48 lbs when going from split finger to three under the bow got much louder is there any timing,balancing or tillering that would help with the noise bow shoots and bare shafts good 500 gr carbons.

Often times just elevating your rest and moving the string nock up a 1/4" or so will make a difference.....or ......just put some cat whisker silencers on it. Just be sure and offset the string silencers too. for example... 7-8" down from the top tip notch, and 9-10" up from the bottom. This makes a big difference.     Kirk

What Kirk just said . I’ve also heard a tip protector changing things .

I completely understand why you say that now that you have Kirk, but could you give the long short of it and your experience with moving the silencers so it can really stick in my head? Id like to get it right the right reasons hah

If the limbs are balanced properly, both tips come forward at the same time, and stop at the same time. After the arrow has left the string..... The string occelates, and the weight of the center serving increases that occelation..... by locating your string silencers in different positions it throws that occelation out of balance having the weight of the cat whiskers in different locations and slows that ocelation down quicker.

Typically there is slightly more pressure put on the lower portion of the string during the draw cycle, which can be increased with a 3 under finger location. so raising the string knock, and the location of  the bottom string silencer will help quiet the bow string.

Check out these slow motion videos and see how much that string, and limb  moves after the shot. Keep in mind that some of these limb designs have a very high preload and stops completely much quicker than many other limb designs.

The second clip here has some paradox arrows first, but then shows the Static tip RC limbs in slow motion....  I took these high speed videos myself in the shop.

thank you very much i was right there with ya until the unbalanced silencers decreasing a more centralized/balanced oscillation. which peters out faster  by taking its energy away. if im hearin ya right.

thanks I will move my strimg leeches and put something on shelf and raise my nock point and see what happens I will let you know

The thing to remember is... Elvis has already left the building before that string starts oscillating, so its not taking away any energy that transfers to the arrow shaft.... But... adding weight to the string in the form of string silencers does slow it down a touch...maybe 2-3 fps...

I moved my silencers on the bottom up a bit around three inches did seem to help a little thanks for the help
