What is stack??

[Budog56]

Hey guys always heard people talking about getting stack in their bow etc..What exactly is it?

[vermonster13]

When a bow increases in poundage quickly or at a heavier rate in the draw curve. A bow may go 3# an inch from 25-28 then jump to 4, 5 or 6 from 28" on and that is what is percieved as stack.

That only needed to be said once. lol

[Budog56]

How can you tell if your bow has it is it just a feel thing or ?? im sorry for some reason the brain isnt registering all this still kinda confused.

[vermonster13]

The bow will get much harder to draw at some point or feel like it hits a wall.

The way to tell it draw it on a scale and write the weight down every inch to 30".Watch for that big gain compared the gain the bow was developing .
 
Often people say a bow stacks, but in reality they ran out of muscle.

Thanks guys I got it now.. for some reason it was to easy for me to understand

It's the special at the IHOP, LOL!

All bows stack eventually. Stacking comes right before the cracking!!!!!!!!!

String angle at the tips is THE factor for stacking.  After shooting ILF limbs on my DAS that gain @2" per inch the last few inches of my draw, I notice a bow stacking pretty easily.  LOL!!!

I heard someone explaing it like this once,  it's when the limbs stop moving more rearward and starts moving more downward.  I don't know if that makes any sense at all but to my mind it fits.

Seth, If we lived a little closer together I'd show you what stack is. I just built a bow that gives new meaning to stack, I can only pull it about 3" with everything I've got! musta put the uni-weft in the wrong place, took me 3 times just to string the thing and it's like pulling on an Iron bar, it will be destroyed today before someone else gets hurt...........Steve

Don't worry about the questions you ask,  none of us knew anything until someone else taught us.
So ask away.

Wow I thought it was when you put one hotcake on top of another!     <><

Aha, I was also wondering what it meant when people said these bows are not stacking - it's another way of saying that the bow is smooth to draw. As someone said all bows will start stacking at a certain point of draw length. So the important thing must be that the bow is not stacking in the range of the shooters draw length plus 5" for example - and that the bow for example up to 5" after draw length has a smooth draw curve - gains less than 2# per inch, as less as possible.

I've always thought of it like this: It's when the string stops pulling the limbs back and starts pulling against the nocks. OR, when the string stops pulling the limbs back and starts an attempt to stretch them like rubber bands on a slingshot( which will never happen )

Well - I did an experiment yesterday with my Atletic - 25 years old French bow. Because it feels very hard to draw. I measured in a manuel way with an draw length arrow indicator from Easton and with a draw weight puller, from 22" to 28" draw. In the range 23"-24,5" it gains 1# per 1", in the range 24,5" - 27" it gains 1,9# per 1", and in the range 27" to 28" it gains 3,0# per 1".

I also while looking in the mirror saw that at my draw length (25,75"), the tip of the limbs are not vertical but have an angle against me. So at this point the bow is beginning to be drawn shorter - wich could explain the jump from 1,9# to 3,0# per 1", that occurs at 27" draw.

This makes me think that my bow is best for one with a short draw length of about 24".
