Back to Earth, Part 2. Now we know that there are no full-carbon arrows and certainly no 100% full carbon arrows. There is another illusion : Carbon arrows cannot bend (?) True, 100% full carbon arrows will not bend because do not exist. But in « reality », carbon-composit shaft can bend. Do not leave them in the car when outside temperatures are high. Your expensive 100% full carbon arrows ( ) do not like that and potentially punish you by giving-up their eventual straightness. Also a/c-composit shafts do not favour such conditions. Not very important but good to know as one small step back to reality. More important is the equalty of the spine over the length of the shaft. Most arrow shafts are made from Pre-peg carbon clothing.It is an illusion to believe that the carbon-fibers are nicely and equally spread in the Pre-peg material.The lower the carbon-fiber content, the less control. Add to that the accumulating tolerances. Has the Wall-thickness of the core of an a/c-composit shaft a nominal tolerance all over the length and/or periphery ? Rather not. Result is that the average spine might be X in the center of the shaft. But…….. what about the spine at other places of same shaft ? How will the spine vary over the length of the shaft ? A snake or a delphin ? The spline….? Might be fine in the centre of the shaft. But what about the rest of the shaft ? 360° equal spine ? This was just one more reason to develop SkyArt « The Arrow » and SkyArt « Emotion » More to follow in Part 3.
