Stacking?

[Scattergun2570]

Can someone explain what it means when a bow "STACKS"?

[Rob DiStefano]

during the draw, the point at which the holding weight jumps radically higher than the average of 2-3#/inch.

Rob hit the nail on the head.

As you draw your bow the weight goes up in increments, usually 2 or 3 lbs per inch.

In a bow that stacks those poundage increments will will increase the further you get toward your anchor.

If it were on a line graph you would see it easily as that line showing the poundage at specific inches would start to climb at a very steep rate.

If you every pull one that stacks badly, you will understand the concept immediately.

Merry Christmas and God bless,Mudd

Would stacking after say 29" be a sign that the limbs are near their failure (breaking) point? Or it's it mostly just in the design of the bow?

not failure, limb design - or lack thereof.

Lots of guys will confuse being over bowed with stacking.These are two completely seperate issues.

Here is a theoretical FD curve showing a bow beginning to stack.



Here is an FD curve of an actual bow that does not show any stack.

Every bow will stack eventually when it is drawn far enough.  The best case is to have a bow that will not stack at your draw length.

I agree with what Bill at Zipper Bows said. There is a big difference between the draw of my 2 recurves. My old Pearson cougar is 40# @ 28 and stacks like a bugger. However, my new 55@28 super grizzly draws smooth back to my 30" draw. I never expected that out of a 58" bow at that draw. Loving it!
