Which way should my arrows spin?
Webster's dictionary defines the word helix as ' to turn round ' or ' something spiral in form ' like an ordinary screw thread . Screw threads turned to the right in a clockwise direction are a right helix. (0059.jpg ) If the screw threads were a left helix we would have to turn the screw to the left in a counter clockwise direction to install it into a material .
When building arrows , we can install our feathers with right or left helix or with no helix at all, as in ''straight fletch ''. This helical fletching helps spins out any imbalances in the arrowhead or in the arrow shaft and stabilizes the tail of the arrow, while the arrow follows through on it's trajectory . If you mistakenly mix them on the same arrow you could possibly be the first archer in your neighborhood , to shoot around a corner or around a tree.
A left spiral or helical fletch will spin or torque the arrow counter clockwise and away from the bow , if the bow is held in the left hand . (0088.jpg ) A right wing fletch will torque or spiral the tail of the arrow towards the bow when the bow is held in the left hand. ( 0082.jpg ) Consider the opposite if you hold your bow in your right hand . Releasing an arrow with feathers that spins to the left when the bow is held in the left hand , will have less contact with the bow ,than an arrow with feathers that spin to the right........ This is physics . My archery supply store here in western Canada sells only right wing feathers and right wing fletching jigs although the left ones can be ordered in. A large arrow manufacturer recently appeared as an article in P.A. advising us they manufacture mostly left wing spiral fletching on their arrows . This is probably due to extensive testing by such archery greats as Fred Bear , Ben Pearson , their own testing labs , and others. If you hold your bow in your left hand when shooting there is probably good reason to have your arrows spin to the left . If you hold your bow in your right hand when shooting , there is probably good reason to have your arrows spin to the right............again it's physics. This would certainly apply if you are shooting other than a center shot bow. If you are shooting a center shot bow , the spin is not so critical , but is still a factor. (0093.jpg )
