I have been assuming the oscillation would be forward and backward because of the direction the string is moving when in fact the string could be oscillating right and left as well. This would seem to be able to spin an arrow right or lefts as the oscillation cycles move up and down the string...
So it seems it has to be oscillation! When the bow is fired the limbs begin to move outward pulling the string back toward its at rest location. Because of the amount of force that is placed on the string it actually moves past its at rest position, when this happens it sends shock waves (for...
Dave, I used a mechanical release that put no influence on the string and I shot with fingers, two completely different types of releasing of the string and the arrow shafts still rotated left on its own axis.
Compound bows come with a number of setups, one is a wheel on top and a cam on the bottom. They typically fall off to about 20% or the draw weight when you are at full draw. The draw curve is different than a recurve, as you draw a recurve the draw weight increases and on release it falls off...
I took bare unfletched shafts and placed a dot on the arrow near the nock end at 12:00. I stood just in front of a target and shot the arrows into the target. The arrow rotated on its own axis to the left slightly, the further I moved back the more they rotated. We test various bows and on some...
Some friends and I have been having some discussions about why an unfletched arrow will spin right when shot from some bows and left when shot from other bows. We have taken bows and shot a series of different arrows and every arrow out of that bow went in the same direction.
So I gues I...
