Hey fellas,
i have heard alot about staking bows? just wondering what that means :oops:
thanks michael
when you draw the bow back and it stacks on the poundage too much near the end of the draw

whats it do ??
it gets harder to pull it back, and is not a smooth draw.
it might be smooth up to a certain point and then gets real hard real quick
like lifting weights and someone puts a 20 kilo weight on top all of a sudden.not that extreme obviously but hopefully you get the idea
a good quality recurve bow should draw back smoothly all the way without feeling too hard all of a sudden near the end of the draw :D
And to add to what Jeffro said a bow that stacks is inefficient. Any good bow recurve or longbow will not stack, a bow that stacks is not storing energy. You can try it for yourself, get a set of scales and measure the weight at every inch to your draw length and mark it of graph paper. All of the area under the line is stored energy, a graph that shows a nice fat curve or convex is storing a lot of energy or shows how efficient a bow is, a concave graph where the graph goes up sharply towards the end of of the draw is inefficient because it is not storing the energy. That's a simplistic over view but a good to test your bow for yourself...Glenn...
from personal experience I can tell you that you get little return from your effort by taking a bow out to a draw length where it stacks. And of heavier bows it can feel more solid than a brick wall. I have a 92@28 woomera longbow that stops me dead at about 31 inches most days, about one day in three do I manage to repeat shots at full draw of 32. The string angles are right on 90 degrees so the limbs are pushing up as much as forwards which doesn't help arrow speed much.
And all that is only if you don't blow the bow up! Bows are generally not tillered to be used to a draw where they stack, so you are taking a risk with the limb integrity too.
Fellas do a little experiment were you make a bow from a stick [ no self bow jokes] and draw it until the string angles approach 90 degrees as measured from between the string and belly of the bow.
As the string angle approaches 90 degrees the make shift bow will stack and then the string will pull off the nocks above 90 degrees. If the bow breaks this is not an indication that stacking means a bow is overstrained just that the bow was overstrained. Stacking is all about string angle. Reduse string angle wih correct tiller and alonger bow , this equals more energy transferred to the arrow.
