Hi all,
I've noticed, on some of my longer bows, not really hand shock, but more of a residual twang or string vibration after the arrow is on its way. It's not loud, by any means. I have plenty of brace height, no wrist slap to speak of (only if I release badly). Could this be because;
1) I hear every creak and tick and rub, and am paranoid
2) Arrows that are too light or heavy (I believe they are spined within five pounds of the bow)
3) Something else altogether
Just curious,
Frode

Frode , i would think with too light of arrows . other than that might be string material . although if your like me could be a whole lot of #1 im always lookin for probs with my bows , like driving your truck u can feel when somethings wrong
-
Sounds like your arrows are physically light. How much do they weigh and how does that compare with the draw weight? Heavier arrows absorbe more of the energy from the bow so you feel less in your hand.

Are you plucking the string? Jawge

I agree with george see if you fingers on the string are paralell to it when you draw or if you are trying to twist the string the opposite way. This hand position will make the shot feel wierd and give you more noise. I do however usally find that my bows shoot arrows better when they are splined about 5 lbs heavier than the bow.
-
what is your string material? you might need something heavier with less memory or maybe something lighter with more. you sure dont want your bow to sound like a harp! let us know when you figure it out. jason

@bucksbuoy; All my strings so far have been B-50, at least 14 strands.
@Jawge and twcbow; I wondered about that, too. last time I was out I had someone spot me, and apparently my form is OK (which is odd, as I'm the sort who falls down the stairs while going up, and still manages to end up sitting on the floor at the top :-\).
@PatB and ken75; My scale is not the best, but it shows just a hair under an ounce, so 400 grains, maybe? They're 5/16" sitka spruce shafts with 100 grain field points.

Your brace height might be too low. Light arrows, and plucking the string will also cause twang.

I don't understand this "plucking the string"
And I do draw with my fingers parallel to the string..but one HAS to for a cherokee pinch release. I've also seen many pictures of natives drawing with fingers parallel. It feels natural for me.

Well it would be similar to holding your bow on your lap and strumming it. When you are shoooting the string should roll easily off your fingers. Jawge

Plucking the string means you're trying to open your hand quickly, and let go of the string. Impossible. Your hand isn't fast enough. Instead, you have to come to full draw, and then relax your hand and pull through the string, allowing it to slip out of your grasp.
Don't let go of the string... let the string go. Mmmm... takes much plactiss glasshoppa.

Odds areit's too lite of arrow. Think of it this way. Compound shooters in some of the upper classes of 3D comp (ASA and local shoots) push the limits on the grains per pound on arrows. At 60#, I was shooting 156 grain arrow 26.5 draw and got allot of "twang" Put some puff balls (string silencers) and increase the arrow weight to 12 or 13 gpp and I think you'll find a big diff. in the sound.
-
Well, I think I'll try making some heavier arrows. I'm needing to make some anyway, and I usually put it off until I absolutely have to. What do you recommend for weighing, something like a small postal scale?
Thanks,
Frode

That's what I use. Weighs ozs and grams.

I use a digital ounce/gram scale I bouught at Wally World for about $15. Then I go to this website to convert from grams to grains.

437.5 grains to the ounce!
