Title: Draw weight same as holding weight?
Post by: orangputihkgu on September 16, 2012, 03:43:43 pm
Hello there warbow archers and bowyers!!

That maybe a folly question but: is the weight you have to hold against with your bow hand the same as the weight you pull with your draw hand?
I think it should be less because of the energy stored in the bow limbs but I am not certain.
Do you have an answer?

And if the weight is different, how much different?

Thanks a lot....CHRIS

im pretty sure the energy is being stored in the limbs, but that doesn't take away from the weight you are drawing with you hands, because it is the force you are applying to the bow that is creating the energy that is being stored in the limbs( if that makes sense)

I have put the handle of a bow on the scale and pulled the string to get the draw weight.  I have also slung the string over a hook on the scale and pulled the same bow.  Same reading on the scale.  The resistance of the bow in your hand is equal to the resistance of the string against your fingers.

In archery, the 'draw weight' is the equivalent amount of weight you are holding at full draw. In other words, my 100#@30" draw weight warbow is equivalent to holding back 100 #s of weight at it's full draw. Draw weight is really only a scale of reference in determining the amount of force (weight) in pounds it requires to draw a particular bow.

Yes ! It is a folly question.
The tension on either end of a spring/rope/steel bar etc is by definition the same.
The pressure on you hand will feel less as it is spread over a larger area.
It's a bit like asking if a 1 yard rule is the same length measured from either end ;D (yes it is)

In fairness, he may be slightly confused with wheelie bow experience, where the draw weight is less than the holding force at full draw.  Mechanical advantage and all that jazz.  The force on the bow hand would still equal the holding weight, but I am not sure why this is relevant, except for the fact that this is what the OP asked about.

Since you are not supposed to be holding for more than a fraction of a second, the question is irrelevant.

??? Even if you're only holding for a fraction of a second, you're still holding the draw weight of the bow. 100#s is 100#s, regardless.

Hello there,

thanks for answering my folly question with patient and humor!  ;D

@JW_Halverson: thx for measuring the bow from both "ends". Your reply cleared my question immediately.

cheers...chris

If you have drawn i00 pounds, an additional fraction of a second is irrevelant.

No problem!  Glad I helped in some small way. 

Do you build or want to build war bows?  Or just interested in shooting them?
