Adjust the limb alignment: Adjust the limb alignment by adjusting the limb bolts. Turn the limb bolts clockwise to increase the limb tension, which will decrease the bow’s draw weight and increase the bow’s speed. Turn the limb bolts counterclockwise to decrease the limb tension, which will increase the bow’s draw weight and decrease the bow’s speed.
All arrows irrespective of their material, length, diameter or spine grouped around the point sighted whether shot with three-finger, pinch or mechanical release, with a glove or with bare fingers.
With the type of arrows rests used on “C” and “D” bows, the arrows were free to move to the left (bow held in left hand) without obstruction and the arrows had an opportunity to readjust themselves after receiving the side push caused by the string going around the finger tips, and they there fore grouped around the point aimed at.
With the pinch release or its equivalent in a mechanical releasing device, all four sets of arrows shot from all four bows grouped around the point sighted on, the sight being kept in the vertical middle of the bow at all times and adjusted vertically to take care of the different weights of the arrows in the different sets.
If matching target arrows for spine to a fine degree is as difficult and important as many archers appear to believe, then the center shot bow of proper design has an advantage over other types, in that arrows of greatly different spines will group together on the target without any allowance being made for differences in spine.
The center shot bow also has the advantage that very light arrows may be shot with heavy bows giving flatter trajectories than are possible with bows that force the arrow to bend in order to go around it.
The 28″-7/32″ diameter 290 grain “Z” arrows performed very well when shot with a 45 lb. “D” type bow. This “Z” arrow has so little spine it became permanently bent when shot just once with a 45 lb. bow of conventional design.
No doubt hundreds of center shot bows have been made and shot but it is seldom that one is seen in use. However, as indicated above, properly designed center shot bows have certain inherent advantages which, when more generally recognized, should increase their use considerably, and may become the favorite type with many archers.
最初に取り上げた迷訳は”So angular motion can be thought of as continually changing linear direction, as long as the continually changing linear directions follow the path of a curve.”という英語ですが、「つまり、回転(角)運動は連続的に曲線の経路をたどり、絶えず方向を変えていく直線の向きだと考えることができます。」と私は訳しますが、理解していただけるだろうか。
自分はそのままローディングと訳しました。写真上の赤い矢印(押し手から引き手の肩まで)を”銃身”とみなし、そこに矢を装填する(矢を”銃身”を同一直線上に置く)という動作となります。同一直線上に置く以上、これ以上、LAN2が回転してしまうと、ズレてしまうので、2次元的な回転運動はここまで。ここからは微小な回転運動に「移行」し、瞬間的な直線運動(instantaneous linear motion)になり、クリッカーを落とし、リリースに繋がります。
