The ulimate connection between string and arrow.

The Zapfenkugel

The basic idea for the Zapfenkugel was the plasticball which was on the market since the beginning of the 90-ties. The idea was to improve the material. The slip of the plasticball was not satisfactorily. During the tests I found out that the arrow needs an additional lateral steering, so to speak a guidance in the Nockenbett, in order to prevent the arrow from rotating and to otimize transmission from string to arrow. Specially with the finger release strong torsions from the string are transmitted to the Nocke. This is even more the case with string walking (Barebow), because through the different grips on the string the vector changes permanently and the bow is submitted to more or less trimming. The inner shape of the Kugelnocke is the ideal supplement to the Zapfenkugel.

Advantage of this combination:

Absolute axial acceleration of the shaft.

Constant transmission of power through articulary as well as tippng free inter-action of Nock and Zapfenkugel.

Even if the string is submitted to different torsions a slipping guarantee of 360 degrees is to be achieved as well as absolute even release resistance.
Complete symmetrical shape, therefore no loss of “static balance”, free angle of more than 80 degrees, which means the Nocke is ideal for compound shooting with release. The Nock can not be released voluntarily when the bow is stressed.
A separate distance keeper is to be recommended.
The short Nockwing are responsible for an extremely fast release of string and Nock without long lasting torsion powers of the string, thus permitting a softer arrow with less spinning results. This actually is necessary as such, since the arrow is subject to considerably less lateral trimming with this combination.

Many archers change from their traditional Nockpoint to the Zapfenkugel without adapting their equipment accordingly, which does not lead to satisfactorily results. Each change on the existing equipment requires meticular adaptations on all components of equipment.

The Zapfenkugel requires a 16.22 fast-flite string. Measures see graph.

The wrapping of the Zapfenkugel is easy. With a piece of stringfilament which has to be put through the Zapfenkugel the beed is to be mounted before the last Stringeye ends. In order to put the beed easier over the string, the end of the string has to be twisted. Do not use pointy tools in order to avoid burrs which can harm the slip. (A special tool will bee available soon) So that there are no problems for 20 or 22 String users. Now the second Stringeye has to be finished and the string has to be twisted and fixed at the bow. The beed has to be fixed in the middle according to the graph.

Please contact me if you have any questions.

The Nockpointplacement normally is higher than its normal adjusment. You have to try. A one to 2 mm correction on the finished Middlewinding is always tolerated. (push strongly the Winding.)

You can order the Zapfenkugel directly with me or buy it in archery stores In case your salesman does not dispose about the beed within shortly you can load down more adresses. We use the Zapfenkugel since 1994 and did not note any negative side effects. Positive feed back from all over the world supports our good experience.
Also the Worldchampion Women Bare-Bow Monika Jentges Germany, is using this system over years!

Please contact me in case one or the other archer among you has problems with this combination. I’m ready to help.
Time permitting, I will extend these sides and convey my 25 year long archery experience to you. The Barebow-archery will have priority. That’s the discipline I’m most familiar with and where my heart beats.
