Pivotball for ballnock
Regular price €7,50| The plastic ball that has been on the market since the early 1990s was the basic idea for the pivot ball. In terms of the idea, it could actually only be improved through the material. The slippage of the plastic ball was not satisfactory. In the course of the tests, the realization also developed that the arrow needs additional lateral control, i.e. guidance in the cam bed, to prevent the arrow from twisting and to optimize the power transmission from the string to the arrow. Strong twisting of the string hits the nock, especially with finger release. This is all the more the case with string walking (blank bow) because the angle of force changes constantly due to the different gripping on the string and the bow is more or less trimmed as a result. The inner shape of the ball cam is the ideal complement to the pivot ball. The advantages of this combination are: Absolute axial shaft acceleration Constant power transmission through the pivoting, tilting moment-free interaction of nock and pivot ball. Slip finding entity on 360°, ie absolutely the same release resistance even with different twisting of the string in the draw Absolutely symmetrical shape, so no loss of "static balance" Clearance angle of over 80°, which means the nock is also ideal for compound shooting with release. The nock cannot be deliberately nocked out when the bow is drawn. The short still wings ensure a lightning-fast separation of the string and nock without longer lasting lateral forces of the string (allows an arrow that is one spin value softer or even causes it because the arrow with this combination is much less trimmed laterally. The trunnion ball allows for 16-22 stang fast-flite string. Dimensions see graphic! |

| Wrapping the trunnion ball is very simple, the trunnion ball is unwound before the end of the last eye of the string, using a piece of string yarn that is passed through the trunnion ball. Twist the end of the string together a little beforehand so that it goes over the string more easily. Do not use sharp objects, otherwise a degree could arise that would no longer ensure proper slipping. Now finish the 2nd string eye and screw in the string and stretch it on the bow. Fix the ball with the middle winding according to the graphic on the right. If you have any questions, you can contact me at any time. A small video film is also being prepared, it will then document the individual steps and will be available for download here! | |||||||||||||||||||

| The still point boost is usually slightly higher than its normal setting! Try out!! 1-2mm correction on the finished center winding are always possible. (Push the winding firmly!) | |||||||||||||||||||
| Y ou can obtain the pivot ball and the matching nocks from specialist retailers . The distribution of "this system" is in the hands of " Amboprodukts ". We have been using the pivot ball with the ball cam since 1994 and have not experienced any negative side effects. Positive feedback from home and abroad supports our experience. Our world champion in bare archery, Monika Jentges , has also been using this system for years. | |||||||||||||||||||
