is there anyway to take the stack out of a bow
Sometimes if the limbs are left paralell up until the last 6" or so on a short recurve it may stack more noticably. If you taper them in from the fades and gradually to the tips it won't stack as bad. It also depends on if you used tapered laminations or not, and what the rate of taper is. I've noticed less stacking when I use serveral thin laminations around .050 thick and none of them tapered. I just taper the limb profile for the entire length of the limbs.
Stacking is the result of string angle at the nock hitting 90Deg at full draw. Beyond that the bow bends very little if any so you don't get the "spring" effect. Flipping the tips(recurving) will decrease the string angle and allow more tip movement and less stack.
are you getting ready to build one or is this a bow you have?

String angle is one factor but if the bow is so short the string angle causes the stacking effect then nothing can be done. there are many other causes besides just string angle, the biggest being limb profile. With longbows and self bows it's different story. I've seen longbows over 68" long that you can feel it stack at about 26" inches, in most cases they were whip ended (bending mostly at the tips) the stacking on those could be corrected by re tillering. I've seen laminated longbows stack as well if the limbs were constructed out of all tapered laminations and they were a bit whip ended too. I stated in my first post about tapering the width from the tips down to the fades and that will lessen the effects of stacking.
